Gattungsgemäße Vorrichtungen besitzen eine rotierende Bürste, die aus dem Kunstrasenplatz beziehungsweise Kunststoffrasenplatz das Füllgut, zum Beispiel Sand und/oder Gummigranulat auskehrt und dabei auch auf dem Platz aufliegenden Schmutz wie Blätter, Papier und so weiter abkehrt.Generic devices have a rotating brush, which sweeps out of the artificial turf pitch or plastic turf the contents, for example, sand and / or rubber granules and thereby turns away on the square resting dirt such as leaves, paper and so on.

Mit Hilfe der in der Vorrichtung vorgesehenen Trenneinheit werden diese Partikel von dem Füllgut getrennt und hernach das Füllgut wieder auf den Kunstrasenplatz in geeigneter Weise ausgebracht.
Im Stand der Technik ist es bekannt, als Trenneinheit ein Sieb vorzusehen, wobei das Füllgut durch das Sieb fällt und die Schmutzpartikel so getrennt werden. Der anfallende Schmutz und andere Partikel werden dann in einem Sammelbehälter aufgefangen.
With the help of the separation unit provided in the device, these particles are separated from the contents and afterwards the contents are again applied to the artificial turf pitch in a suitable manner.
In the prior art, it is known to provide a sieve as a separation unit, wherein the contents fall through the sieve and the dirt particles are separated. The resulting dirt and other particles are then collected in a collection container.

Im Stand der Technik ist es bekannt, das Sieb als Schublade zu realisieren und daher eine Vielzahl von Schubladen vorzusehen, die sich jeweils durch eine unterschiedlich aussiebbare Korngröße unterscheiden. Dies ist zum einen aufwendig und zum anderen unflexibel.In the prior art, it is known to realize the screen as a drawer and therefore to provide a plurality of drawers, which differ in each case by a different ausiebbare grain size. This is on the one hand consuming and on the other inflexible.

Das Dokument DE 41 36 517 A1 zeigt eine Kehrmaschine für sandverfüllte Kunstrasenflächen, wobei ein Sammelbehälter der Kehrmaschine in seinem Bodenbereich zur Rückführung von aufgenommenem Füllmmaterial ein Sieb aufweist, dessen Siebgröße an die Korngröße des Füllsandes angepasst ist. Eine verwendete Kehrwalze kann in einer Art Teilverzahnung gegensinnig ausgerichtete, V-förmig angeordnete Kehrleisten aufweisen, wobei die mittlere Spitze in Umlaufrichtung nachläuft und die Randbereiche voreilen.The document DE 41 36 517 A1 shows a sweeper for sand-filled artificial turf surfaces, wherein a collecting container of the sweeper in its bottom region for the return of recorded Füllmmaterial has a sieve whose sieve size is adapted to the grain size of the filling sand. A used sweeping roller may have in a kind of partial toothing oppositely oriented, V-shaped arranged sweeping strips, wherein the middle peak travels in the direction of rotation and lead the edge regions.

Das Dokument EP 13 48 49 5 A2 zeigt eine Siebvorrichtung mit aufeinandergepressten Siebelementen, wobei die Siebelemente jeweils eine im Wesentlichen glatte, von einer Mehrzahl von Sieblöchern durchbrochene Oberfläche aufweisen und mit ihren Oberflächen gegeneinander verschiebbar aufeinanderliegen. Die Siebvorrichtung wird dabei so ausgebildet, dass die einander zugewandten Oberflächen der Siebelemente durch zumindest ein Spannelement im Wesentlichen spaltfrei aufeinandergepresst gehalten sind.The document EP 13 48 49 5 A2 shows a screening device with sieve elements pressed onto one another, wherein the sieve elements each have a substantially smooth surface which is perforated by a plurality of sieve holes and with their surfaces lie on one another so as to be displaceable relative to one another.

Es ist Aufgabe der vorliegenden Erfindung eine Vorrichtung wie eingangs beschrieben vorzuschlagen, die vielseitiger einsetzbar sein soll.It is an object of the present invention to propose a device as described above, which should be more versatile.

Zur Lösung dieser Aufgabe geht die Erfindung aus von einer fahrbaren Vorrichtung wie eingangs beschrieben und schlägt vor, dass ein stufenlos veränderliches Trennmaß für das Trennen der Partikel von dem Füllgut vorgesehen ist. Mit der fahrbaren Vorrichtung mitfahrend ist eine entsprechende Anordnung vorgesehen, durch die das Trennmaß, welches in der Trenneinheit zum Einsatz kommt und zum Trennen der Partikel von dem Füllgut (also Schmutz vom eingestreuten Sand oder Gummigranulat) dient, jederzeit veränderbar ist. Hierdurch wird erreicht, dass während des Einsatzes der fahrbaren erfindungsgemäßen Vorrichtung das Trennmaß veränderlich ist, um zum Beispiel den speziellen Gegebenheiten des zu wartenden und zu reinigenden Kunstrasenplatzes kurzfristig zu entsprechen. Daneben ist das Trennmaß auch anhand der physikalischen Partikelbeschaffenheit veränderlich ausgeführt. Dies bedeutet, dass eine Anpassung des Trennmaßes und damit der Trennleistung der Trenneinrichtung in Abhängigkeit davon erfolgt, ob es sich bei den Partikeln um Schmutz handelt, der von dem Füllgut, das nach dem Trennvorgang wieder auf einem Kunstrasenplatz ausgebracht werden soll, getrennt wird oder aber, ob die Trennung der Partikel des Füllgutes, wie dies beispielsweise bei der Aufbereitung eines Kunstrasenplatzes der Fall ist, vorgesehen ist. Insbesondere in den Fällen, in denen eine Windsichtung des durch die Vorrichtung aufgenommenen Partikelgemisches vorgesehen ist, ist das Trennmaß anhand der Partikelmasse veränderlich ausgebildet. Hierbei wird über das veränderliche Trennmaß die Beaufschlagung des Partikelgemisches mit einem Luftstrom geregelt, der bewirkt, dass nur die Partikel in einem definierten Massebereich aussortiert werden.To achieve this object, the invention is based on a mobile device as described above and proposes that a continuously variable separation measure for the separation of the particles is provided by the contents. With the mobile device traveling along a corresponding arrangement is provided, by which the separation measure, which is used in the separation unit and used to separate the particles of the contents (ie dirt from the interspersed sand or rubber granules), is changeable at any time. This ensures that during the use of the mobile device according to the invention, the separation measure is variable, for example, to meet the specific conditions of the waiting and to be cleaned artificial turf pitch in the short term. In addition, the size is also made variable based on the physical particle nature. This means that an adaptation of the separation size and thus the separation efficiency of the separator takes place depending on whether it is the particles are dirt that is separated from the contents, which is to be applied after the separation process again on an artificial turf field, or whether the separation of the particles of the filling material, as is the case for example in the preparation of an artificial turf pitch, is provided. In particular, in the cases in which an air classification of the particle mixture accommodated by the device is provided, the separation dimension is variable based on the particle mass. In this case, the admission of the particle mixture with an air flow is controlled via the variable separation measure, which causes only the particles are sorted out in a defined mass range.

Des Weiteren wird durch den erfindungsgemäßen Vorschlag erheblicher Aufwand eingespart. Im Stand der Technik ist es bekannt, für die einzelnen festen, diskreten Trennmaße separate Trenneinheiten in Form von entsprechenden Sieben mit entsprechenden Siebgrößen vorzuhalten. Dies führt zu einem entsprechenden Aufwand für die Bereitstellung der Siebe und, wie ausgeführt, zu einer entsprechenden Unflexibilität im Einsatz. Da letztendlich alle verfügbaren Trennmaße an der fahrbaren Vorrichtung mitfahrend ausgebildet sind, kann dieser zusätzliche Aufwand an Geräten eingespart werden und insbesondere können auch Rüstzeiten gespart werden, da die Einstellung des entsprechenden Trennmaßes im Einsatz unmittelbar erfolgt.Furthermore, considerable savings are saved by the proposal according to the invention. In the prior art it is known for to provide the individual solid, discrete separation dimensions separate separation units in the form of corresponding sieves with corresponding sieve sizes. This leads to a corresponding expense for the provision of the sieves and, as stated, to a corresponding inflexibility in use. Since ultimately all available separation dimensions are designed to ride on the mobile device, this additional cost of equipment can be saved and in particular can also be saved set-up times, since the setting of the appropriate separation measure in use is immediate.

Durch die insbesondere stufenlose Veränderbarkeit des Trennmaßes ist es auch möglich, die erfindungsgemäße fahrbare Vorrichtung nicht nur für Reinigungsaufgaben, sondern zum Beispiel auch für Wartungszwecke einzusetzen. Oftmals besteht das Füllgut aus zwei verschiedenen Partikelsorten, zum Beispiel Sand und Granulat mit jeweils unterschiedlicher Korngröße. Da sich die Korngrößen unter Umständen nur um wenige 1/10 mm unterscheiden, kann mit Hilfe des erfindungsgemäßen Vorschlages auch eine Separierung des Füllgutes in die verschiedenen beiden Partikelsorten vorgenommen werden, das heißt, die Erfindung ist auf die Reinigungsaufgabe eines entsprechenden Kunstrasenplatzes nicht beschränkt. Neben einer erheblichen Erhöhung der Flexibilität der Erfindung und höherer Verfügbarkeit der Maschine, da die Rüstzeiten für das Wechseln der Siebe entfallen, ist es mit der erfindungsgemäßen Vorrichtung möglich, neben den bekannten Reinigungsaufgaben des Kunstrasenplatzes die erfindungsgemäße Vorrichtung noch zusätzlich auch für Wartungsaufgaben zu verwenden, wenn zum Beispiel das Füllgut entsprechend zu wechseln oder zu bearbeiten ist.Due to the particular stepless variability of the separation measure, it is also possible to use the mobile device according to the invention not only for cleaning tasks, but also, for example, for maintenance purposes. Often, the contents of two different types of particles, for example, sand and granules, each with different grain size. Since the grain sizes may differ only by a few 1/10 mm under certain circumstances, with the help of the proposal according to the invention, a separation of the contents in the different two types of particles can be made, that is, the invention is not limited to the cleaning task of a corresponding artificial turf pitch. In addition to a considerable increase in the flexibility of the invention and higher availability of the machine, since the set-up times for changing the sieves omitted, it is possible with the device according to the invention, in addition to the known cleaning tasks of the artificial turf field, the device according to the invention additionally to use for maintenance tasks, if For example, the contents to change or edit accordingly.

In einer Ausgestaltung der Erfindung ist vorgesehen, dass eine Trenneinheit für die Trennung und teilweise Rückführung der Partikel oder des Füllgutes auf den Kunstrasenplatz vorgesehen ist, wobei die Rückführung unmittelbar aus der Trenneinheit erfolgt. Vorteilhaft an dieser Ausführung ist es, dass nach der Aufnahme des Füllgutes des Kunstrasenplatzes oder jeden sonstigen Sportplatzes eine direkte Rückführung eines Teiles des Füllgutes auf den Kunstrasenplatz innerhalb eines Arbeitsganges erfolgen kann. Das Füllgut beziehungsweise ein durch die Trenneinheit beziehungsweise die Einstellung der Trenneinheit definierte Fraktion des aufgenommenen Füllgutes wird dabei unmittelbar aus der Trenneinheit rückgeführt. Diese Rückführung erfolgt unmittelbar, das heißt in der Trenneinheit wird eine Größenselektion des Füllgutes durchgeführt und der gesamte Anteil des Füllgutes mit einer vorher definierten beziehungsweise durch das Trennmaß vorgegebenen Größe umgehend wieder auf den Kunstrasenplatz zurückgeführt. Eine zusätzliche Verringerung der rückgeführten Menge, die das Vorhandensein eines weiteren, störanfälligen Trennmaßes beziehungsweise einer zusätzlichen, entsprechend ausgeführten Trennvorrichtung notwendig machen würde, erfolgt nicht. Aufgrund des Fehlens einer weiteren Trenneinheit kommt es hier nicht zur Ansammlung von Partikeln, die zu einer Verstopfung der zweiten, unter Umständen fehlerhaft eingestellten Trenneinheit führen kann.In one embodiment of the invention, it is provided that a separation unit for the separation and partial recycling of the particles or the filling material is provided on the artificial turf pitch, wherein the return takes place directly from the separation unit. Advantageous in this embodiment, it is possible that after receiving the contents of the artificial grass pitch or any other sports field direct return of a part of the contents of the artificial turf field can be done within a single operation. The filling material or a fraction of the received filling material defined by the separating unit or the setting of the separating unit is thereby returned directly from the separating unit. This feedback is carried out directly, that is, in the separation unit, a size selection of the contents is performed and the entire proportion of the contents with a previously defined or predetermined by the Trennmaß size immediately returned to the artificial turf pitch. An additional reduction of the recirculated amount, which would necessitate the presence of a further, interference-prone separation measure or an additional, appropriately designed separator, does not occur. Due to the lack of a further separation unit, it does not come to the accumulation of particles, which can lead to a blockage of the second, possibly incorrectly set separation unit.

Die erfindungsgemäße Vorrichtung kann auch so ausgestaltet sein, dass die Trenneinheit einen veränderlichen, insbesondere stufenlos veränderlichen Bereich aufweist und die Trennung der Partikel von dem Füllgut in diesem veränderlichen Bereich der Trenneinheit erfolgt. Des Weiteren ist vorgesehen, dass die Trenneinheit auch aufgrund der Ausführung mit mehreren Bereichen, wovon ein einzelner Bereich veränderlich ausgebildet ist, auch nach einem Verändern des Trennmaßes in der Lage ist, fortlaufend, insbesondere unterbrechungsfrei Partikel von dem Füllgut zu trennen. Eine weitere Ausgestaltung der Erfindung sieht vor, dass die fahrbare Vorrichtung gemäß der Erfindung nicht nur einen veränderlichen Bereich, sondern mehrere veränderliche Bereiche aufweist, die hintereinander angeordnet sind. Die Anordnung hintereinander bedeutet im vorliegenden Fall, dass die Bereiche sowohl prozessual als auch räumlich hintereinander angeordnet sein können. Erfindungsgemäß ist jedoch vorgesehen, dass der Bereich ebenso wie die Bereiche bezüglich des Trennmaßes veränderbar ausgebildet ist beziehungsweise sind.The device according to the invention can also be designed so that the separation unit has a variable, in particular continuously variable range, and the particles are separated from the contents in this variable region of the separation unit. Furthermore, it is provided that the separation unit is also due to the design with multiple areas, of which a single area is changeable, even after changing the separation dimension is able to continuously, in particular interruption-free particles to be separated from the contents. A further embodiment of the invention provides that the mobile device according to the invention not only has a variable range, but a plurality of variable regions, which are arranged one behind the other. The arrangement in succession in the present case means that the areas both processual and spatial can be arranged one behind the other. According to the invention, however, it is provided that the area as well as the areas with respect to the separation dimension is or are changeable.

Gemäß der Erfindung ist dabei vorgesehen, dass auch die einzelnen Bestandteile des Füllgutes als Partikel von dem übrigen Füllgut durch die Erfindung trennbar ist.According to the invention, it is provided that the individual constituents of the filling material as a particle of the remaining contents can be separated by the invention.

In einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die Trenneinheit eine Vielzahl von Öffnungen für das Hindurchtreten des Füllgutes aufweist und so die Trenneinheit die Partikel von dem Füllgut trennt und die Öffnungsweite veränderlich, insbesondere stufenlos veränderlich ist. Nach diesem Vorschlag der Erfindung wird als Trennmaß die Öffnungsweite der Öffnungen der Trenneinheit, wie sie zum Beispiel bei einem Sieb Verwendung findet, eingesetzt. Hierauf ist die Erfindung aber nicht beschränkt, es können in gleicher Weise auch andere Varianten einer Trenneinheit erfindungsgemäß verwendet werden. Hier wäre zum Beispiel an eine Windsichtung zu denken, bei welcher mit einem entsprechenden Sog, dessen Stärke wiederum das Trennmaß darstellt, die Trenneigenschaften einer so ausgestatteten Trenneinheit festgelegt werden.In a preferred embodiment of the invention it is provided that the separation unit has a plurality of openings for the passage of the contents and so the separation unit separates the particles from the contents and the opening width is variable, in particular continuously variable. According to this proposal of the invention is used as a separation measure the opening width of the openings of the separation unit, as used for example in a sieve, used. However, the invention is not limited to this, and other variants of a separation unit can likewise be used according to the invention in the same way. Here, for example, to think of an air classification, in which with a corresponding suction, the strength of which again represents the separation measure, the separation properties of a separation unit so equipped are set.

Weist die Trenneinheit jedoch Öffnungen auf, so sind diese günstigerweise in einer Ebene angeordnet. Aufgrund dieser Anordnung werden Partikelstauungen in der Trenneinheit vermieden, da nur ein einziger Trennvorgang erfolgt.However, if the separation unit has openings, these are conveniently arranged in one plane. Due to this arrangement, particle blockages in the separation unit are avoided since only a single separation process takes place.

Von großem Vorteil ist, dass an der fahrbaren Vorrichtung eine Einstellvorrichtung für das Trennmaß vorgesehen ist. Hierdurch ist es möglich, die fahrbare Vorrichtung den jeweiligen Gegebenenheiten auf dem Kunstrasenplatz unmittelbar und kurzfristig anzupassen, da die Einstellvorrichtung immer an der Vorrichtung verfügbar ist, weil sie mit dieser mitfährt.It is of great advantage that an adjustment device for the separation dimension is provided on the mobile device. This makes it possible to adapt the mobile device the respective circumstances on the artificial turf pitch immediately and at short notice, because the adjuster is always available on the device because it moves with it.

In einer erfindungsgemäßen Variante ist vorgesehen, dass als Abtragvorrichtung eine um eine Achse rotierende Bürste vorgesehen ist. Alternativ zu einer Bürste ist als Abtragvorrichtung zum Beispiel auch eine entsprechende Absauganlage einsetzbar, die auf dem Kunstrasenplatz aufliegende Partikel und Füllgut, ähnlich einem Staubsauger, absaugt. Der Einsatz einer rotierenden Bürste ist aber unter Umständen effektiver, da ein größerer Anteil von Füllgut aus dem Kunstrasen herausarbeitbar ist. Die Bürste besitzt dabei zum Beispiel Borsten, die aufgrund der rotierenden Bewegung zwischen den Halmen des Kunstrasen eingreifen und so das Füllgut samt Partikeln herauskehren. Die Rotationsachse ist dabei bevorzugt parallel zur Ebene des Kunstrasens, in der Regel horizontal orientiert.In a variant according to the invention, provision is made for a brush rotating about an axis to be provided as the removal device. As an alternative to a brush, for example, a corresponding extraction system can also be used as the removal device, which sucks particles and contents resting on the artificial turf area, similar to a vacuum cleaner. However, the use of a rotating brush is possibly more effective, since a larger proportion of contents from the artificial turf can be worked out. The brush has, for example bristles, which intervene due to the rotating movement between the blades of the artificial turf and thus sweep the contents including particles. The axis of rotation is preferably parallel to the plane of the artificial turf, usually oriented horizontally.

Neben der Realisierung einer Bürste mit Borsten ist aber auch eine Variante erfindungsgemäß vorgesehen, nach welcher an der Bürste auch entsprechend einzelne massive Zinken angeordnet sind, die gegebenenfalls auch in Kombination mit einer Borstenbürste zusammenwirken. Die Zinken können dabei gegebenenfalls eine etwas größere Länge aufweisen und somit tiefer in das in den Kunstrasen eingestreute Füllgut eingreifen und dieses entsprechend auflockern. Es wird dann gegebenenfalls ein geringerer Teil auch mit herausgekehrt, es erfolgt aber auch eine Auflockerung des eingestreutes Füllgutes im Kunstrasen.In addition to the realization of a brush with bristles but also a variant is provided according to the invention, according to which on the brush according to individual massive tines are arranged, which optionally cooperate in combination with a bristle brush. The tines may optionally have a slightly greater length and thus engage more deeply in the interspersed in the artificial turf product and this loosen up accordingly. It is then possibly a lesser part with also turned out, but there is also a loosening of the interspersed filling in artificial turf.

Erfindungsgemäß wird dadurch mit einem Bearbeitungsvorgang, das heißt, mit einmal Abfahren des gesamten Rasens, mehrere Arbeitsgänge ausgeführt, nämlich ein Entfernen von Schmutzpartikeln und anderen Partikeln, also eine Reinigung des Platzes, gegebenenfalls auch eine Reinigung des ausgekehrten Füllgutes, verbunden mit einer Auflockerung des nicht ausgekehrten Füllgutes und gleichzeitig ein Aufrichten der Halme des Kunstrasens.According to the invention, a number of operations are carried out with one machining operation, that is to say once the entire lawn has been driven off, namely a removal of dirt particles and other particles, ie a cleaning of the space, optionally also a cleaning of the swept filling material, connected with a Loosening of the non-swept filling and at the same time raising the blades of the artificial turf.

Es ist gefunden worden, dass sich unter Umständen ein besseres Arbeitsergebnis ergibt, wenn die Bewegungskomponente der Bürste im Bereich des Kunstrasens in Richtung der Fahrtrichtung ist. Gegebenenfalls besteht hierzu aber auch eine andere Variante, nämlich dass die Bewegungskomponente der Bürste im Bereich des Kunstrasens zur Fahrtrichtung entgegengerichtet ist.It has been found that under some circumstances a better working result results if the movement component of the brush in the area of the synthetic turf is in the direction of travel. Optionally, however, there is also another variant, namely that the movement component of the brush is directed in the region of the synthetic turf to the direction of travel.

Geschickterweise ist erfindungsgemäß eine Höhenverstellbarkeit der Abtragvorrichtung vorgesehen, wodurch sich der Wirksamkeitsbereich der Abtragvorrichtung einstellen läßt. Die Höhenverstellbarkeit wirkt in der Regel rechtwinklig zum Kunstrasenplatz und bestimmt letztendlich die Eindringtiefe der Abtragvorrichtung, zum Beispiel bei der Ausgestaltung der Abtragvorrichtung als rotierende Bürste (gegebenenfalls auch mit Zinken), bis auf welches Höhenniveau die Borsten der Bürste Partikel und Füllgut aus dem Rasen herauskehren.Cleverly, a height adjustment of the removal device is provided according to the invention, whereby the effectiveness range of the removal device can be adjusted. The height adjustment usually acts at right angles to the artificial turf pitch and ultimately determines the penetration depth of the removal device, for example, in the embodiment of the removal device as a rotating brush (possibly also with tines), up to which level the bristles of the brush particles and contents from the lawn.

In einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die Trenneinheit als Doppelsieb ausgebildet ist, mit einem ersten und einem hierzu parallel angeordneten, zum ersten relativ verschiebbaren zweiten Sieb, wobei die Siebe jeweils eine Vielzahl von Sieböffnungen aufweisen und die übereinander angeordneten Sieböffnungen die Öffnungen der Trenneinheit bilden. Vorteilhafterweise sind die beiden zum Einsatz kommenden Siebe im Doppelsieb identisch ausgestaltet und um ein gewisses Maß zueinander relativ beweglich, zum Beispiel durch die Einstellvorrichtung.In a preferred embodiment of the invention it is provided that the separation unit is designed as a double screen, with a first and a second arranged parallel thereto, the first relatively movable second sieve, wherein the sieves each having a plurality of sieve openings and the sieve openings arranged one above the other openings of the Form separation unit. Advantageously, the two screens used in the twin-wire are designed identically and to a certain extent relative to each other relatively movable, for example by the adjustment.

Für die Ausgestaltung der beiden Siebe bestehen zwei Varianten. Bei einer ersten Variante wird das erste Sieb an der erfindungsgemäßen Vorrichtung ortsfest angeordnet und das zweite Sieb ist hierzu beweglich. In der zweiten Variante sind beide Siebe zum Beispiel gegensinnig zueinander bewegbar. Geschickterweise sind beide Siebe zueinander parallel orientiert, wobei dies nicht eine Anordnung ausschließt, bei welcher diese beiden Siebe auch einen kleinen Winkel zueinander einschließen. Auch dies sei noch von dem Begriff "parallel" umfaßt. Geschickterweise wird dabei eine möglichst parallele Anordnung gewählt, um ein Verklemmen des zu siebenden Füllgutes aufgrund der Abwinkelung zwischen den beiden Sieben zu vermeiden.There are two variants for the design of the two screens. In a first variant, the first sieve is fixedly arranged on the device according to the invention and the second sieve is movable for this purpose. In the second variant, both screens are for Example in opposite directions to each other movable. Cleverly, both screens are oriented parallel to each other, this does not exclude an arrangement in which these two screens also include a small angle to each other. This too is still covered by the term "parallel". Cleverly a possible parallel arrangement is chosen to avoid jamming of the contents to be screened due to the bending between the two screens.

Ein Vorteil dieser Ausgestaltung mit den Sieben nach der Erfindung liegt insbesondere darin, dass diese sehr einfach zu lösen und ausgesprochen effektiv ist. Alternativ hierzu ist erfindungsgemäß vorgesehen, die Trenneinheit zum Beispiel durch eine Luftsichtungsanordnung zu realisieren.An advantage of this embodiment with the screens according to the invention lies in the fact that it is very easy to solve and extremely effective. Alternatively, it is provided according to the invention, to realize the separation unit, for example by an air seal arrangement.

Geschickterweise werden gleichartige Sieböffnungen in den beiden Sieben verwendet. Das heißt, dass die beiden Siebe gleichartig ausgebildete Sieböffnungen besitzen und auch die Stege, die zwischen den Sieböffnungen vorgesehen sind, jeweils gleichartig sind. So ergibt es sich, dass in einer Stellung der beiden Siebe des Doppelsiebes zueinander eigentlich nur ein Sieb wirksam ist, da das zweite Sieb vollständig von dem ersten Sieb verdeckt ist. Diese Stellung entspricht dann auch gleichzeitig der Anordnung mit dem größten Trennmaß beziehungsweise Siebmaß, da hier die Öffnungen mit dem weitesten Abmessungen zur Verfügung stehen.Cleverly, similar sieve openings are used in the two sieves. This means that the two screens have identically formed screen openings and also the webs, which are provided between the screen openings, are similar in each case. Thus, it turns out that in a position of the two wires of the twin wire to each other actually only one sieve is effective, since the second sieve is completely covered by the first sieve. This position then also corresponds to the arrangement with the largest separation size or Siebmaß, since here are the openings with the largest dimensions available.

In einer bevorzugten Variante der Erfindung ist vorgesehen, dass die Sieböffnungen rechteckig oder quadratisch sind und die Verschiebebewegung zwischen den beiden Sieben diagonal hierzu ist. Bevorzugt wird eine quadratische Ausgestaltung der Sieböffnung, die sich in vielfacher Weise auf den jeweiligen Sieben befindet, angestrebt, da dadurch in einfacher Weise, wie vorgeschlagen, die Kantenlänge der Sieböffnung in beide Richtungen gleichartig verringert oder verändert werden kann. Erfolgt die Verschiebebewegung, wie beschrieben, in diagonaler Richtung eines Quadrates, so taucht in anteilig gleicher Weise das zweite Sieb unter dem ersten Sieb hervor und die Stege des zweiten Siebes verringern gleichartig die Sieböffnung des ersten Siebes zu einer resultierenden Öffnung der Trenneinheit. Eine solche Anordnung gewährleistet daher eine gleichartige Verstellbarkeit der Trenneinheit bei hoher Güte des Trennergebnisses.In a preferred variant of the invention it is provided that the screen openings are rectangular or square and the sliding movement between the two screens is diagonal thereto. Preferably, a square configuration of the sieve opening, which is located in many ways on the respective sieves, sought, since in a simple manner, as proposed, the edge length of the sieve opening can be reduced or changed in both directions similar. If the displacement movement, As described, in the diagonal direction of a square, the second sieve under the first sieve emerges in a proportionately similar manner and the webs of the second sieve similarly reduce the sieve opening of the first sieve to a resulting opening of the separation unit. Such an arrangement therefore ensures a similar adjustability of the separation unit with high quality of the separation result.

Erfindungsgemäß ist vorgesehen, an Stelle von quadratisch aus gebildeten Sieböffnungen auch rechteckig ausgestaltete Sieböffnungen einzusetzen. Dabei ist zu beachten, dass die Erfindung auch bei mehreckig ausgebildeten Sieböffnungen grundsätzlich verwendbar ist. Auch runde Sieböffnungen und so weiter sind einsetzbar, wobei bei solchen Formen der Sieböffnung eine Verringerung des Trennmaßes unter Umständen keine gleichmäßige Verringerung wie bei einer quadratischen Ausgestaltung der Sieböffnung resultiert.According to the invention, it is provided to use rectangular sieve openings instead of square sieve openings formed. It should be noted that the invention is basically usable even with polygonal screen openings. Also round screen openings and so on are used, with such forms of screen opening a reduction in the size of the separation may not result in a uniform reduction as in a square configuration of the screen opening.

In einer einfachen Ausgestaltung der Erfindung, die aber sehr wirkungsvoll und einfach zu bedienen ist, ist vorgesehen, dass als Einstellvorrichtung ein Schieber oder ein Stellrad vorgesehen ist, dessen Betätigung auf die Relativposition der beiden Siebe wirkt. Dabei besitzt die Einstellvorrichtung gegebenenfalls eine entsprechende Feststellung des Schiebers oder Stellrades, damit sich das einmal ausgewählte Trennmaß nicht selbstständig wieder verändert. Die Anordnung ist dabei problemlos so zu realisieren, dass eine stufenlose, sogar eine möglichst feinfühlige und auch gut reproduzierbare Einstellung des Trennmaßes durch die erfindungsgemäß vorgeschlagene Einstellvorrichtung möglich ist. In geeigneter Weise ist dabei die Einstellvorrichtung auch mit einer entsprechenden Anzeige ausgestattet, um das gerade verwendet Trennmaß dem Benutzer anzuzeigen. Dies kann in einfacher Weise durch entsprechend mechanisch bewegte Zeiger und dergleichen erfolgen.In a simple embodiment of the invention, which is very effective and easy to use, it is provided that a slider or a thumbwheel is provided as an adjustment, the operation of which acts on the relative position of the two screens. In this case, the adjustment device optionally has a corresponding determination of the slider or setting wheel, so that once selected separation size does not change automatically again. The arrangement is to be realized without any problem so that a stepless, even as sensitive and well reproducible adjustment of the size of the separation by the inventively proposed adjustment is possible. Suitably, the adjustment device is also equipped with a corresponding display in order to display the currently used degree of separation to the user. This can be done in a simple manner by appropriately mechanically moving hands and the like.

Sowohl die Abtragvorrichtung, wie auch die Trenneinheit erstrecken sich geschickterweise über die gesamte Breite der fahrbaren Vorrichtung, um einen möglichst hohen Abdeckgrad zu erreichen und so eine möglichst große Bearbeitungsbreite zur Verfügung zu stellen. Hieraus resultiert, dass unter Umständen ein verhältnismäßig hoher Strom von ausgebautem Füllgut an der Trenneinheit angelangt, der über die sich in Fahrtrichtung ein gewisses Stück erstreckende Trenneinheit zu führen ist. Es ist daher erfindungsgemäß vorgesehen, dass die Trenneinheit eine Transportanordnung für das Füllgut aufweist, um innerhalb der erfindungsgemäßen Vorrichtung für einen entsprechenden Weitertransport des Füllgutes zu sorgen. Dabei wird angestrebt, dass die Transportanordnung so realisiert ist, dass das an der in Fahrtrichtung vorne angeordneten Abtragvorrichtung ausgebaute Füllgut an der in Fahrtrichtung nachfolgenden Trenneinheit entsprechend aufbereitet wird und nach der Trenneinheit wieder sofort in den Platz eingebaut wird und zwar möglichst an der Stelle, an der es ausgebaut wurde. Es ist daher geschickterweise gegebenenfalls eine Regelung oder Steuerung für die Geschwindigkeit des Füllgutes durch die Transportanordnung in der Trenneinheit vorgesehen.Both the removal device, as well as the separation unit extend skillfully over the entire width of the mobile device in order to achieve the highest possible degree of coverage and thus to provide the largest possible processing width available. The result of this is that, under certain circumstances, a relatively high flow of expanded product has reached the separating unit, which has to be guided over the separating unit extending in the direction of travel. It is therefore provided according to the invention that the separation unit has a transport arrangement for the contents to provide within the device according to the invention for a corresponding further transport of the contents. In this case, it is desirable that the transport arrangement is realized in such a way that the filling material removed at the removal device arranged in front in the direction of travel is treated accordingly on the separation unit following in the direction of travel and is immediately re-installed into the space after the separation unit, if possible at the location it was expanded. It is therefore cleverly provided, if appropriate, a control or control for the speed of the filling material by the transport arrangement in the separation unit.

Für die Ausgestaltung der Transportanordnung sind mehrere Varianten nach der Erfindung denkbar. Zunächst ist auf das Prinzip eine Schüttel- oder Schwingrinne abzustellen, wie dies noch weiter beschrieben werden wird. Aber auch der Einsatz eines Luftstromes kann als Transportmittel für das Füllgut in der Trenneinheit dienen, wie dies zum Beispiel bei einer Windsichtung realisierbar ist.For the design of the transport arrangement, several variants according to the invention are conceivable. First, the principle of a shaking or vibrating trough off, as will be described further. But even the use of an air flow can serve as a means of transport for the contents in the separation unit, as can be realized, for example, in an air classification.

In einer weiteren Ausgestaltung der Erfindung ist vorzugsweise vorgesehen, daß das Doppelsieb spitzwinklig geneigt ist, derart, daß der in Fahrtrichtung vorne liegende Auffangbereich höher als der Endbereich des Doppelsiebes. Es ergibt sich so und in einfaeher Weise eine Transportanordnung für das Füllgut, da dieses auf der sich ausbildenden schrägen Ebene abläuft.In a further embodiment of the invention, it is preferably provided that the twin wire is inclined at an acute angle, such that the collecting area located in front in the direction of travel is higher than the end area of the twin wire. It results in such a way and in einfaeher Way a transport arrangement for the contents, since this runs on the forming inclined plane.

Vorzugsweise wird dabei ein Neigungswinkel gegenüber der Horizontalen von ca. 1° bis 15°, insbesondere ca. 3° bis 9° vorgesehen. In dem in den Zeichnungen gezeigten Ausführungsbeispiel ist beispielsweise ein Neigungswinkel von ca 5° gewählt. Des weiteren hilft die geneigte Anordnung des Doppelsiebes aber auch, daß auf dem Sieb anlaufende Füllgut möglichst gleichmäßig der Breite nach, aber auch in Fahrtrichtung zu verteilen. Hierdurch wird insbesondere erreicht, daß ein möglichst gleichmäßiger Einbau des zuvor ausgebauten und dann gereinigten Füllgutes erreicht wird.Preferably, an angle of inclination relative to the horizontal of approximately 1 ° to 15 °, in particular approximately 3 ° to 9 ° is provided. In the embodiment shown in the drawings, for example, an inclination angle of about 5 ° is selected. Furthermore, the inclined arrangement of the twin wire but also helps that on the screen approaching product as evenly as possible to distribute the width, but also in the direction of travel. In this way, in particular, it is achieved that the most uniform possible installation of the previously removed and then cleaned filling material is achieved.

Erfindungsgemäß ist vorgesehen (gegebenenfalls zusammen mit einem spitzwinklig geneigten Doppelsieb), daß die Transportanordnung durch ein als Schüttelsieb ausgebildetes Doppelsieb realisiert ist. Durch ein Schütteln beziehungsweise Vibrieren des Doppelsiebes wird bereits ein Transportieren erreicht, wenn diese vertikale Bewegung nämlich mit einem geneigten Doppelsieb erfolgt. Das als Schüttgut ausgestaltete Füllgut (Sand, Gummigranulat oder andere schüttbaren Güter) tanzen dann regelrecht auf dem Doppelsieb und werden aufgrund der geneigten Stellung von dem höheren zu dem niedrigeren Bereich transportiert. Teilweise fällt natürlich das Füllgut nach und nach durch die Öffnungen des Siebes, die herauszufilternden Partikel allerdings werden durch die Schüttelbewegung in den niedriger gelegenen Endbereich der Trenneinheit transportiert.According to the invention is provided (optionally together with an acute angle inclined twin wire) that the transport arrangement is realized by a trained as a vibrating screen twin wire. By shaking or vibrating the twin wire transporting is already achieved when this vertical movement is done namely with an inclined double screen. The configured as bulk material (sand, rubber granules or other pourable goods) then dance downright on the twin wire and are transported due to the inclined position of the higher to the lower area. Partly, of course, the contents gradually falls through the openings of the screen, but the particles to be filtered out are transported by the shaking movement in the lower end of the separation unit.

In einer bevorzugten Ausgestaltung der Erfindung ist für das Schüttelsieb ein Exzenterantrieb vorgesehen. Durch den Exzenterantrieb wird nicht nur ein Hochschleudern (ausschließlich eine vertikale Bewegung) des Füllgutes erreicht, sondern die Exzenterbewegung beinhaltet auch eine horizontale Bewegungskomponente. Es ergibt sich somit ein Hoch- und Nach-Hinten-Bewegen des zu trennenden Füllgut-Partikel-Gemisches.In a preferred embodiment of the invention, an eccentric drive is provided for the shaker screen. Due to the eccentric drive not only a high spin (only a vertical movement) of the contents is achieved, but the eccentric movement also includes a horizontal component of movement. It thus results in a high and back-to-move the product-to-be-separated mixture to be separated.

Dabei ist die Anordnung so gewählt, daß im Endbereich des Siebes, also am niedrigsten Punkt des Siebes, tatsächlich nur noch eine vertikale Bewegung zu beobachten ist. Hier ist auch eine weitere Transportbewegung in der Regel nicht mehr notwendig, da hier dann andere Mechanismen greifen.The arrangement is chosen so that in the end of the screen, so at the lowest point of the screen, actually only a vertical movement is observed. Here is another transport movement usually no longer necessary, since then other mechanisms take effect.

Erfindungsgemäß ist vorgesehen, daß in der Trenneinheit die Partikel entsprechend des eingestellten Trennmaßes, zum Beispiel des Kornmaßes oder des Siebmaßes, von dem Füllgut getrennt werden. Das Füllgut fällt zum Beispiel durch das erfindungsgemäß vorgesehene Doppelsieb nach unten durch und wird sogleich wieder in den Kunstrasen eingebaut, indem es durch das unten offene Doppelsieb direkt auf den Boden fällt. Die Erfindung ist nicht darauf beschränkt, daß das Füllgut nach der Trenneinheit gleich wieder in den Kunstrasenplatz fällt, wie das in einer ersten erfindungsgemäßen Variante vorgesehen ist, es ist vielmehr auch möglich, das so aufbereitete (weil getrennte) Füllgut in einen solchen Behälter abzuführen oder erst zu einem späteren Zeitpunkt wieder einzubauen.According to the invention it is provided that in the separation unit, the particles are separated from the contents according to the set separation size, for example, the grain size or the Siebmaßes. The contents fall through, for example, by the inventively provided double screen down and is immediately reinstalled in the artificial turf by falling through the bottom open double screen directly on the floor. The invention is not limited to the fact that the contents after the separation unit immediately falls back into the artificial turf pitch, as provided in a first variant of the invention, but it is also possible to dissipate the so treated (because separate) contents in such a container or to reinstall at a later date.

Nach der Trenneinheit ist auch für die von dem Füllgut getrennten Partikel eine entsprechende Fördermöglichkeit vorzusehen. Erfindungsgemäß werden hierzu ein oder mehrere Fördereinheiten vorgesehen, die die Partikel nach der Trenneinheit insbesondere in einen Sammelbereich fördern. Die Partikel, in der Regel entsprechende Schmutzpartikel, Papierchen, Tüten, aber auch Laub usw., eben all das, was auf einem Sportplatz beziehungsweise Kunstrasenplatz aufliegen kann, werden in einem Sammelbereich entsprechend aufgefangen.After the separation unit, a corresponding delivery option must also be provided for the particles separated from the contents. According to the invention, one or more conveying units are provided for this purpose, which convey the particles after the separating unit, in particular into a collecting area. The particles, usually corresponding dirt particles, paper, bags, but also leaves, etc., just what can rest on a sports field or artificial turf are collected accordingly in a collection area.

Hierfür sind erfindungsgemäß auch mehrere unterschiedliche Fördereinheiten nach der Erfindung vorgesehen.For this purpose, the invention also provides several different conveyor units according to the invention.

Gängigerweise ist der Sammelbereich als eine Schmutzwanne ausgeführt.Usually the collecting area is designed as a dirt trough.

In einer weiteren erfindungsgemäßen Variante ist vorgesehen, daß der Sammelbereich an der Vorrichtung vorgesehen ist, das heißt, die Schmutzwanne zum Beispiel als entleerbare Schublade an der fahrbaren Vorrichtung vorgesehen ist. Es ist auch möglich, daß sich der Sammelbereich gemäß der Erfindung an dem die fahrbare Vorrichtung bewegenden Schleppfahrzeug oder einem hiervon getrennten anderen Fahrzeug, welches mit der fahrbaren Vorrichtung mitfährt, befindet. Hierdurch sind gegebenenfalls deutlich größere Sammelbereiche realisierbar.In a further variant of the invention it is provided that the collecting area is provided on the device, that is, the dirt pan is provided, for example, as an emptying drawer on the mobile device. It is also possible for the collecting area according to the invention to be located on the towing vehicle which is moving the mobile device or of a separate vehicle which is traveling with the mobile device. As a result, if necessary, significantly larger collection areas can be realized.

Als Fördereinrichtung für die Partikel sind mehrere Varianten nach der Erfindung vorgesehen. Zunächst ist zum Beispiel ein Querförderer vorgesehen. Durch einen Querförderer, zum Beispiel eine rotierende Förderschnecke mit gegensinnig angeordneten Schnecken, ist es möglich, den Schmutz, der sich zum Beispiel im Seitenbereich der fahrbaren Vorrichtung ansammelt, in einem mittleren Bereich zu sammeln und dort zum Beispiel zentral abzusaugen. Durch eine solche Anordnung wird daher erreicht, daß der Schmutz oder die Partikel zuverlässig aus der Vorrichtung abgeführt werden.As a conveying device for the particles, several variants are provided according to the invention. First, for example, a cross conveyor is provided. By means of a transverse conveyor, for example a rotating conveyor worm with screws arranged in opposite directions, it is possible to collect the dirt accumulating, for example, in the side area of the mobile device, in a central area and to extract it centrally there, for example. By such an arrangement is therefore achieved that the dirt or particles are reliably removed from the device.

Gängigerweise ist als Fördereinrichtung nach der Erfindung aber auch eine Absauganlage vorgesehen, die, ähnlich wie ein Staubsauger, die Schmutzpartikel usw. in einen großen Sammelbehälter absaugt. Erfindungsgemäß ist durchaus vorgesehen, daß beide Gruppen von Fördereinrichtungen miteinander kombiniert werden und zum Beispiel zuerst eine Querförderung (quer zur Fahrtrichtung der verfahrbaren Vorrichtung) und hernach eine entsprechende Absaugung kombiniert werden.Normally, as a conveyor according to the invention but also an extraction system is provided, which sucks, like a vacuum cleaner, the dirt particles, etc. in a large sump. According to the invention, it is certainly provided that both groups of conveyors are combined with each other and, for example, first a transverse conveying (transverse to the direction of travel of the movable device) and afterwards a corresponding suction are combined.

In einer bevorzugten Variante der Erfindung ist vorgesehen, daß eine Füllstandsanzeige von in der Trenneinheit vorliegendem Füllgut vorgesehen ist. Eine solche Füllstandsanzeige wird bevorzugt zum Beispiel am Ende des Doppelsiebes angeordnet, um somit anzuzeigen, wenn sich in der fahrbaren Vorrichtung zuviel Füllgut ansammelt. In einer solchen Situation ist nämlich dann die Fahrgeschwindigkeit der Vorrichtung gegenüber dem Boden zu hoch und daher zu reduzieren, um dem zu reinigenden Füllgut ausreichend Zeit zu lassen, durch das Doppelsieb wieder auf den Boden zu fallen. Letztendlich ist die Anordnung so zu betreiben, daß der Strom von durch die Abtragvorrichtung aufgenommenem Füllgut und der Strom von durch die Trenneinheit gesäubertem Füllgut gleich ist.In a preferred variant of the invention it is provided that a level indicator is provided by present in the separation unit filling material. Such a fill level indicator is preferably arranged, for example, at the end of the twin-wire, so as to indicate when too much filling material accumulates in the mobile device. In such a situation, the speed of travel of the device relative to the ground is then too high and therefore to be reduced in order to allow sufficient time for the product to be cleaned to fall back to the ground through the twin-wire screen. Ultimately, the arrangement is to be operated so that the flow of material picked up by the removal device and the flow of product cleaned by the separation unit are the same.

In einer bevorzugten Variante der Erfindung ist ein Zentralantrieb für die Rotation der Bürste, der Fördereinrichtung und/ oder der Transportanordnung vorgesehen. Üblicherweise, so sieht es auch eine erfindungsgemäße Variante vor, wird die fahrbare Vorrichtung von einem separaten Fahrzeug, zum Beispiel einem Schleppfahrzeug, einem Traktor oder ähnlichem, geschleppt. Solche Schleppfahrzeuge besitzen in der Regel einen ausreichend starken Motor, da die Anordnung in der Regel so dimensioniert ist, daß mit diesem Motor auch weitere mechanische Teile angetrieben werden können. Hierzu ist eine entsprechende Zapfaufnahme zur Übertragung des Drehmomentes genormt vorhanden und der Zentralantrieb gemäß der Erfindung besitzt eine Kupplungsstelle, um diesen an den Antrieb eines die Vorrichtung bewegenden Schleppfahrzeuges anzuschließen.In a preferred variant of the invention, a central drive for the rotation of the brush, the conveyor and / or the transport arrangement is provided. Usually, as it also provides a variant according to the invention, the mobile device is towed by a separate vehicle, for example a towing vehicle, a tractor or the like. Such tractors usually have a sufficiently strong engine, since the arrangement is usually dimensioned so that with this engine, other mechanical parts can be driven. For this purpose, a corresponding Zapfaufnahme for transmitting the torque is standardized and the central drive according to the invention has a coupling point to connect them to the drive of the device moving towing vehicle.

Die Anordnung eines Zentralantriebes schließt aber nach der Erfindung in keinster Weise aus, daß die einzelnen Elemente, die Bürste und die Fördereinrichtung beziehungsweise die Transportanordnung, eigenständige Antriebe besitzen. In einer dritten Variante ist auf der Vorrichtung mitfahrend ein eigener, als Zentralantrieb dienender Motor vorgesehen. Dies kann zum Beispiel ein Elektromotor oder auch ein Verbrennungsmotor sein. Von diesem zentral angeordneten Motor wird dann in geeigneter Weise über entsprechende Getriebe oder Wellen usw. das Drehmoment auf die jeweils vorgesehenen Elemente übertragen.However, the arrangement of a central drive does not exclude according to the invention in any way that the individual elements, the brush and the conveyor or the transport arrangement, have independent drives. In a third variant, a separate, serving as a central drive motor is provided on the device along. This can be for example an electric motor or an internal combustion engine. From this centrally located Motor is then suitably transmitted via appropriate gear or shafts, etc., the torque to the respective intended elements.

Gemäß der Erfindung ist die fahrbare Vorrichtung als geschleppte Vorrichtung, zum Beispiel mit Hilfe eines Schleppfahrzeuges, oder als selbstfahrende Vorrichtung, zum Beispiel in einem entsprechenden Fahrzeug, realisierbar.According to the invention, the mobile device as a towed device, for example by means of a towing vehicle, or as a self-propelled device, for example in a corresponding vehicle, feasible.

Das hier vorgestellte erfindungsgemäße Konzept wird üblicherweise für eine Bearbeitungsbreite von ca. 900 mm ausgelegt.The inventive concept presented here is usually designed for a processing width of about 900 mm.

Durch die ebenfalls zur Erfindung zählende fahrbare Trennvorrichtung, welche aus mindestens zwei nebeneinander angeordneten, fahrbaren Vorrichtungen - wie beschrieben - besteht, werden die vorgenannten Vorteile übernommen, aber gleichzeitig die Bearbeitungsbreite entsprechend vervielfacht. Die Effizienz beziehungsweise die Bearbeitungsgeschwindigkeit mit Hilfe einer solchen erfindungsgemäßen Trennvorrichtung steigt erheblich.By counting also to the invention mobile separation device, which consists of at least two juxtaposed, mobile devices - as described - consists, the aforementioned advantages are taken over, but at the same time multiplies the processing width accordingly. The efficiency or the processing speed with the aid of such a separating device according to the invention increases considerably.

Geschickterweise wird in einer erfindungsgemäßen Variante der fahrbaren Trennvorrichtung vorgesehen, daß der Aufbau der einzelnen Vorrichtungen zueinander symmetrisch ist, wodurch sich zum Beispiel in der Mitte, zum Beispiel bei der ersten Vorrichtung links oder bei der zweiten Vorrichtung rechts der Absaugkanal anordnet, der zentral für beide Vorrichtungen an dem Schleppfahrzeug angeordnet ist.Cleverly provided in a variant of the invention of the movable separating device that the structure of the individual devices is symmetrical to each other, which, for example, in the middle, for example, in the first device on the left or in the second device on the right of the suction arranges, the central for both Devices is arranged on the towing vehicle.

Dabei muß die Anordnung der beiden Vorrichtungen nicht auf gleicher Höhe nebeneinander sein, sie können bezüglich der Fahrtrichtung auch etwas versetzt nebeneinander gemäß der Erfindung sein.In this case, the arrangement of the two devices must not be at the same height next to each other, they may also be slightly offset side by side with respect to the direction of travel according to the invention.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel schematisch dargestellt.In the drawing, the invention is shown schematically in one embodiment.

In Fig. 1 ist die erfindungsgemäße fahrbare Vorrichtung 2 schematisch dargestellt. Sie besteht aus einem verhältnismäßig langen, aber kompakten, niedrigbauenden Gehäuse, welches über Vorderräder 21 und Hinterräder 22 auf dem Kunstrasen verfahrbar ist. Die bevorzugte Fahrtrichtung ist mit dem Pfeil 20 (hier nach links gezeichnet) vorgegeben. Im hinteren Bereich 25 ist eine entsprechende Anschlußanordnung, zum Beispiel für ein Schleppfahrzeug, vorgesehen, da das hier gezeigte Ausführungsbeispiel als geschleppte fahrbare Vorrichtung 2 realisiert ist.In Fig. 1 the mobile device 2 according to the invention is shown schematically. It consists of a relatively long but compact, low-housing, which is movable over front wheels 21 and rear wheels 22 on the artificial turf. The preferred direction of travel is given by the arrow 20 (drawn here to the left). In the rear region 25, a corresponding connection arrangement, for example for a towing vehicle, is provided, since the embodiment shown here is implemented as a towed mobile device 2.

Für eine leichtere Steuerung der gesamten Vorrichtung 2 sind die Vorderräder 21 um eine vertikale Drehachse drehbar und daher die ganze Anordnung auch in Kurven fahrbar.For easier control of the entire device 2, the front wheels 21 are rotatable about a vertical axis of rotation and therefore the entire arrangement can also be driven in curves.

Die Anordnung ist so getroffen, daß die wesentlichen Elemente der Vorrichtung 2 in einem Gehäuse 23 angeordnet sind und die Höhenlage dieses Gehäuses 23 mit seinen Einbauteilen gegenüber den Vorderrädern 21 durch die Höhenverstellung 12 veränderbar ist. Es resultiert hieraus eine vertikale Einstellbarkeit, die durch den Doppelpfeil 13 angedeutet ist. Die Höhenverstellung 12 ist hier zum Beispiel als Handkurbelrad realisiert. Es kann auch ein motorischer Antrieb sein.The arrangement is such that the essential elements of the device 2 are arranged in a housing 23 and the height position of this housing 23 with its built-in parts relative to the front wheels 21 by the height adjustment 12 is variable. This results in a vertical adjustability, which is indicated by the double arrow 13. The height adjustment 12 is realized here, for example, as a handwheel. It can also be a motor drive.

In Fahrtrichtung 20 nach den Vorderrädern 21 schließt sich in dem Gehäuse 23, gleich nach der Höhenverstellung 12, zunächst eine Abtragvorrichtung 1 an. Diese Abtragvorrichtung 1 ist in dem hier gezeigten Ausführungsbeispiel als rotierende Bürste 10 realisiert, die um die horizontale Achse 11 rotiert. Der hierfür notwendige Antrieb ist zur Erhöhung der Übersichtlichkeit nicht gezeigt. Der Flugkreis der Bürste 10 steht gegenüber der durch die Verbindungen der Reifen 21, 22 gekennzeichneten Rasenoberfläche etwas vor. Dieser Eingriff der Bürste 10 in den Kunstrasen erlaubt es, entsprechend dort ausgebrachtes Füllgut aus ihm herauszukehren. Durch die Einstellbarkeit der Höhenlage mit Hilfe der Höhenverstellung 12 kann dies variiert werden.In the direction of travel 20 after the front wheels 21 closes in the housing 23, immediately after the height adjustment 12, first a removal device 1 at. This removal device 1 is realized in the embodiment shown here as a rotating brush 10 which rotates about the horizontal axis 11. The necessary drive is not shown for clarity. The circle of the brush 10 is slightly opposite the turf surface characterized by the connections of the tires 21,22. This engagement of the brush 10 in the artificial turf makes it possible to sweep out correspondingly discharged there from him contents. Due to the adjustability of the altitude by means of the height adjustment 12, this can be varied.

Die Rotationsrichtung der Bürste 10 ist zum Beispiel hier in Uhrzeigerrichtung, wodurch sich ergibt, daß der untere Bereich der Bürste, der in den Kunstrasen eingreift, in der gleichen Richtung ist, wie die Fahrtrichtung 20. Aus dem Kunstrasen ausgekehrtes Füllgut mit Partikeln wird von der Bürste in den oberen Bereich des Gehäuses 23 transportiert und in den Auffangbereich 33 einer in Fahrtrichtung 20 der Abtragvorrichtung 1 nachfolgenden Trenneinheit gefördert.The direction of rotation of the brush 10 is, for example, here in the clockwise direction, whereby it follows that the lower portion of the brush, which engages in the artificial turf, in the same direction as the direction of travel 20. Filled out of the artificial turf with particulate particles is from the Brush transported in the upper region of the housing 23 and conveyed into the collecting area 33 of a downstream in the direction of travel 20 of the removal device 1 separation unit.

In dem hier gezeigten Ausführungsbeispiel besteht die Trenneinheit 3 aus einem geneigt angeordneten Doppelsieb 30, dessen vorderes Fünftel ungefähr als Auffangbereich 33 vorgesehen ist.In the embodiment shown here, the separation unit 3 consists of a tilted double screen 30, the front fifth is provided approximately as a collecting area 33.

Es ist eine Einstellklappe 34 oberhalb des Doppelsiebes 30 vorgesehen. Diese Einstellklappe 34 ist um eine horizontale Achse schwenkbar und erstreckt sich über die gesamte Breite des Gehäuses 23 beziehungsweise der fahrbaren Vorrichtung 2. Es ergibt sich so die Möglichkeit, die Größe des Auffangbereiches (das heißt, dessen Längserstreckung in Fahrtrichtung gesehen) einzustellen. Die Stellung der Einstellklappe 34 bestimmt damit letztendlich den Aufprallpunkt des von der Bürste 10 in die Trenneinheit 3 geförderten Füllgutes. Diese Stellklappe steuert somit die Abgabe des gereinigten Füllgutes mit dem Ziel, einen möglichst homogenen, gleichmäßigen Einbau des gereinigten Gutes zu erreichen.There is an adjustment flap 34 above the twin wire 30 is provided. This adjustment flap 34 is pivotable about a horizontal axis and extends over the entire width of the housing 23 or the movable device 2. This results in the possibility to adjust the size of the collecting area (that is, the longitudinal extent seen in the direction of travel). The position of the adjustment flap 34 thus ultimately determines the point of impact of the product conveyed by the brush 10 into the separation unit 3. This flap thus controls the delivery of the purified contents with the aim to achieve the most homogeneous, uniform installation of the cleaned material.

Das Doppelsieb 30 ist geneigt angeordnet, derart, daß der Auffangbereich 33 höher liegt als der Endbereich 301.The twin wire 30 is disposed inclined so that the catching portion 33 is higher than the end portion 301.

Des weiteren ist das Doppelsieb 30 durch den Exzenterantrieb 300 derart in Vibration versetzbar, daß sich so eine Transportanordnung für das Füllgut in der Trenneinheit 3 ergibt. Dabei erzeugt der Exzenterantrieb nicht nur eine Auf- und Abbewegung, sondern auch eine horizontale Bewegungskomponente, wodurch das auf dem Doppelsieb 30 aufliegende Füllgut nach oben und nach hinten gestoßen wird. Es ergibt sich somit natürlich eine homogene Verteilung des Füllgutes auf dem Doppelsieb 30.Furthermore, the twin-wire 30 can be set in vibration by the eccentric drive 300 in such a way that a transport arrangement for the filling material in the separation unit 3 results. In this case, the eccentric drive generates not only an up and down movement, but also a horizontal component of movement, whereby the resting on the double screen 30 filling material is pushed upwards and backwards. It follows, therefore, of course, a homogeneous distribution of the contents on the twin wire 30th

Der genaue Aufbau des Doppelsiebes 30 ergibt sich insbesondere aus Fig. 4a bis 4c. Die Anordnung ist so gewählt, daß das Füllgut durch das Doppelsieb 30, wenn die Öffnungsweite des Siebes entsprechend passend ist, hindurchzufallen vermag und somit gleich wieder in den Kunstrasen eingebaut ist. Auf der Oberseite des Doppelsiebes 30 bleiben dann entsprechende Partikel, zum Beispiel Schmutz, Papier, Laub oder andere Gegenstände, deren Durchmesser größer ist als das Trennmaß beziehungsweise der Siebdurchmesser, zurück. Um dieses von dem Füllgut separierte Material abzuführen dient eine Fördereinrichtung 5, die erfindungsgemäß sehr variabel ausgebildet ist.The exact structure of the twin screen 30 results in particular Fig. 4a to 4c , The arrangement is chosen so that the contents through the twin wire 30, if the opening width of the screen is correspondingly suitable to fall through and thus is immediately installed again in the artificial turf. On top of the twin wire 30 then appropriate particles, such as dirt, paper, leaves or other objects, whose diameter is greater than the separation size or the screen diameter, then remain. To dissipate this separated material from the material serves a conveyor 5, which is inventively designed very variable.

In dem in Fig. 1, 2 gezeigten Ausführungsbeispiel ist als Fördereinrichtung 5 eine Absauganlage 50 angedeutet. Tatsächlich ist der Ventilator der Turbine der Absauganlage 50 hier nicht gezeigt. Er befindet sich zum Beispiel auf einem die fahrbare Vorrichtung 2 schleppenden Schleppfahrzeug. Daher umfaßt die Absauganlage 50 hier nur den Absaugkanal 52, der von dem Gehäuse 51 umgeben ist. An dem Gehäuse 51 ist ein entsprechender Absaugschlauch, der zu dem Ventilator beziehungsweise der Turbine führt, anschließbar. Ein Ventilator ist natürlich alternativ auch auf der Vorrichtung anbringbar.In the in Fig. 1, 2 shown embodiment, a suction device 50 is indicated as a conveyor 5. In fact, the fan of the turbine of the exhaust system 50 is not shown here. It is located, for example, on a towing device 2 trailing vehicle. Therefore, the exhaust system 50 here only includes the suction channel 52 which is surrounded by the housing 51. On the housing 51, a corresponding suction hose, which leads to the fan or the turbine, can be connected. Of course, a fan can also be attached to the device as an alternative.

Das Gehäuse 51, und somit der Absaugkanal 52, weiten sich, in Fahrtrichtung gesehen, trichterartig auf. Über die Öffnungen 24 in dem Gehäuse 23 (auf der Oberseite) der fahrbaren Vorrichtung 2 sowie durch die Öffnungen 31 des Doppelsiebes 30 wird damit Luft in den Absaugkanal 52 angesaugt und Partikel, die auf dem Doppelsieb 30 liegen, nach hinten, entgegen der Fahrtrichtung 20, transportiert. Nicht dargestellt ist der Sammelbehälter, der diese Partikel, Schmutz, Unrat, Laub usw., sammelt.The housing 51, and thus the suction channel 52, expand, seen in the direction of travel, funnel-like. Through the openings 24 in the housing 23 (on top) of the mobile device 2 and through the openings 31 of the twin wire 30 so that air is sucked into the suction channel 52 and particles that lie on the twin wire 30, backwards, against the direction of travel 20th , transported. Not shown is the sump that collects these particles, dirt, debris, leaves, etc.

Alternativ könnte eine solche Schmutzwanne aber auch im Bereich des trichterförmigen Gehäuses 51 angeordnet sein.Alternatively, however, such a dirt trough could also be arranged in the region of the funnel-shaped housing 51.

In Fig. 3 ist in einem Ausführungsbeispiel die Trenneinheit 3 schematisch dargestellt. Die Trenneinheit 3 ist hier als Doppelsieb 30 realisiert. Das Doppelsieb 30 besteht aus zwei übereinander angeordneten Sieben 37, 38, die in gewisser Weise relativ zueinander beweglich sind, diese Relativ- beziehungsweise Verschiebebewegung ist mit dem Doppelpfeil 32 angedeutet.
Es ist gut zu erkennen, daß die Öffnungen 31 der Trenneinheit 3 quadratisch ausgebildet sind und die Richtung der Relativ- beziehungsweise Verschiebebewegung 32 der beiden Siebe 37, 38 zueinander parallel zu einer Diagonale dieser quadratischen Öffnungen 31 ist.
In Fig. 3 In one embodiment, the separation unit 3 is shown schematically. The separation unit 3 is realized here as a double screen 30. The double screen 30 consists of two superimposed screens 37, 38, which are movable in a certain manner relative to each other, this relative or displacement movement is indicated by the double arrow 32.
It is good to see that the openings 31 of the separation unit 3 are square and the direction of the relative or Displacement movement 32 of the two screens 37, 38 parallel to each other to a diagonal of these square openings 31 is.

In Fig. 4a, 4b und 4c sind drei verschiedene Stellungen des Doppelsiebes 30 angedeutet, die zu verschiedenen Trennmaßen, wie in Fig. 5a, 5b und 5c gezeigt, führen.In Fig. 4a, 4b and 4c are three different positions of the twin wire 30 indicated that the different separation dimensions, as in Fig. 5a, 5b and 5c shown, lead.

In Fig. 4a ist eine Einstellung gewählt, die das größte Trennmaß (hier zum Beispiel Kantenlänge des Quadrates 10 mm) ergibt.In Fig. 4a a setting is selected which gives the largest separation dimension (here, for example, edge length of the square 10 mm).

Ein erstes Sieb 37 ist feststehend unterhalb dem zweiten Sieb 38 angeordnet. Das erste Sieb 37 und das zweite Sieb 38 sind weitgehend identisch, inbesondere weisen sie die gleiche Ausgestaltung der jeweiligen Sieböffnungen 39 sowie deren Stege 302 auf. Das heißt, die Länge und die Breite der Stege 302 ist jeweils gleich. Bei der in Fig. 4a und Fig. 5a gezeigten Variante verdeckt daher das zweite Sieb 38 das darunter liegende erste Sieb 37 vollständig.A first screen 37 is fixedly disposed below the second screen 38. The first sieve 37 and the second sieve 38 are largely identical, in particular they have the same configuration of the respective sieve openings 39 and their webs 302. That is, the length and width of the lands 302 are the same. At the in Fig. 4a and Fig. 5a Therefore, the second screen 38 completely covers the underlying first screen 37.

Erfindungsgemäß ist an der fahrbaren Vorrichtung eine Einstellvorrichtung 4 vorgesehen, das ist hier zum Beispiel eine entsprechende Einstellschraube oder ein Schiebeklemmverschluß.According to the invention an adjusting device 4 is provided on the mobile device, which is here for example a corresponding adjusting screw or a sliding clamp closure.

In Fig. 4b ist die Wirkung der Einstellvorrichtung 4 angedeutet. Das zweite Sieb 38 ist entlang des Pfeiles 32 leicht nach links versetzt und es tritt darunter das erste Sieb 37, zur deutlicheren Erkennung mit schwarz ausgefüllt, hervor.In Fig. 4b the effect of the adjusting device 4 is indicated. The second screen 38 is slightly offset to the left along the arrow 32 and it emerges below the first sieve 37, filled out for clearer identification with black out.

Deutlich ist zu erkennen, daß die Öffnung 31 der Trenneinheit 3, die in Fig. 5a ja durch die lichte Sieböffnung 39 definiert gewesen ist, jetzt in Fig. 5b reduziert ist auf eine Kantenlänge von 7 mm, vgl. Öffnung 31'.It can be clearly seen that the opening 31 of the separation unit 3, which in Fig. 5a yes has been defined by the clear sieve opening 39, now in Fig. 5b reduced to an edge length of 7 mm, cf. Opening 31 '.

In Fig. 4a, 5c ist nochmals mit Hilfe der Einstellvorrichtung das Trennmaß beziehungsweise die hieraus resultierende Öffnung 31" reduziert worden. Die ursprünglich von dem zweiten Sieb 38 definierte Sieböffnung 39 wird jetzt vollständig aufgeteilt in vier, verhältnismäßig kleine einelne Öffnungen 31", ein Stegkreuz 303 des ersten Siebes 37 liegt vollständig in der quadratischen Sieböffnung 39 des zweiten Siebes 38.In Fig. 4a, 5c Once again, with the aid of the setting device, the separation dimension or the opening 31 "resulting therefrom has been reduced. The sieve opening 39 originally defined by the second sieve 38 is now completely divided into four, relatively small individual openings 31", a web cross 303 of the first sieve 37 completely in the square screen opening 39 of the second screen 38.
