Definitions
- the invention relates to a street sweeper with a suction fan, a suction nozzle and a refuse container, which has a refuse inlet connected to the suction nozzle and an outlet for the suction air, the suction opening of the suction fan being mounted upward in the upper part of the refuse container.
- a known solution according to EP-B1 0 327 483 provides a suction device for a self-propelled street sweeper with a chassis, a suction turbine and a collecting container for the suctioned rubbish.
- the suction turbine is mounted on a movable cover with a vertical axis above the collecting container. This lid is connected to a wall of the collecting container via an elastic member.
- CH-A5 678 342 (Konrad Peter), the state of the art also includes a street sweeper with at least one suction nozzle, a waste container, a suction device and a liquid line for guiding liquid from the waste container into the area of the suction nozzle and binding the dust to obtain the liquid.
- a closing element is arranged in the liquid line, which opens only when there is a suction air stream.
- This object was achieved in such a vehicle with a collecting container arranged on the chassis and having a swing-open rear wall, a throw-in tube guided into the container on the bottom and in a corner area on the cab, a fan located in front of the container and connected to the container via a suction shaft, and an intermediate fan
- the filter arrangement provided in the suction shaft end and container interior is solved in that the container interior is divided into a throw-in area and a settling and air extraction area by a partial partition wall which extends in the longitudinal direction of the container and downwards from the corner of the container, such that the throw-in tube is inclined against the container ceiling provided with a baffle plate arrangement is directed in the throw-in area, and that the filter arrangement has a large area and is attached to the container ceiling from the throw-in area and is shielded by the partial partition.
- the object of the present invention is to provide a street sweeper which has an improved separation of the sweepings from the suction air.
- this is achieved in a street sweeper of the type mentioned at the outset in that the suction opening of the suction fan is mounted centrally in the upper part of the refuse container with respect to length and width.
- the invention is advantageously carried out in such a way that in the upper part of the refuse container, in the area of a cross section of the suction air flow that is substantially larger than the suction opening of the suction fan, a separating grid for the refuse is attached and below the suction fan and the collected waste whose motor is mounted.
- the advantages achieved by the invention are that blocking of the suction opening of the suction fan by the rubbish is very difficult, that part of the exhaust air can be reused by recycling and that good noise reduction is achieved.
- the street sweeper 1 shown comprises a chassis 2, a driver's cab 3, a waste bin 4 mounted on the chassis 2 and a suction device 5 which is mounted in a lid 6 of the waste bin 4.
- the waste bin 4 can be tipped backwards for emptying by means of a bearing 7.
- the garbage is collected by means of rotating brushes 8 in front of a suction nozzle 9 on the bottom 28 and from there reaches the garbage container 4 by means of a pipe 10, where it is directed towards the bottom of the container by means of a deflection plate 11.
- the rubbish bin 4 has a bottom 12 in which the rubbish 13 coming from the pipe 10 collects.
- the lid 6 of the refuse container 4 can be opened on hinges 14.
- the suction device 5 comprises a suction fan 15 which is mounted in the cover 6 approximately in the middle thereof.
- the suction opening 16 of the suction fan 15 is turned away from the garbage inlet 17 of the pipe 10 and from the garbage 18 collected in the floor 12 and is directed upwards.
- the suction fan 15 can suck in the air from the waste container 4 from all sides and therefore has an optimal effect.
- the cross section of the suction air flow, which comes from the refuse container 4 from below around the suction fan 15 to the suction opening 16, is thus in the upper part of the refuse container 4 and before reaching the suction opening 16, it is substantially larger than the cross section of the suction opening 16.
- FIGS. 2 and 3 show that at the level of the suction opening 16 of the suction blower 15 and around this suction opening, a separating grille 19 is mounted to retain the waste. In the area of this large suction air cross section, the entrainment of garbage is reduced due to the lower air speed, so that blocking of the separating grid 19 is less likely.
- the suction air flow has a homogeneous speed distribution around the suction fan 15, speed peaks which could cause sweeping do not occur here.
- a drive motor 20 of the suction fan 15 is mounted below it and inside the waste container 4. This means that no installation space is required above the waste bin 4, and the waste bin 4 together with the waste collected therein result in a substantially improved noise reduction.
- Fig. 4 shows an advantageous embodiment of the air supply and discharge to the refuse container 4 by means of the tube 10.
- a knee tube 22 is connected, in which a movable flap 23 is mounted.
- This flap 23 is adjustably mounted on an axis 24 and causes an outlet of the exhaust air of preferably between 25% and 100% via an opening 25 in the elbow 22.
- the remaining part of the exhaust air between 75% and 0% is led via a discharge pipe 26 to a unit 27 on the floor 28 comprising the suction nozzle 9 (see FIG. 1).
- This portion of the exhaust air which is returned through the discharge pipe 26 is used in the assembly 27 in order to determine the absorption effect for the waste, e.g. in the form of dust.
- the opening 25 in the knee tube 22 is opened completely by means of the flap 23. No air is now returned and the suction nozzle 9 can be lifted up without scattering the waste, as e.g. when large amounts of leaves are ingested.

Description
Die Erfindung betrifft eine Strassenkehrmaschine mit einem Sauggebläse, einer Saugdüse sowie einem Kehrichtbehälter, welcher einen mit der Saugdüse verbundenen Kehrichteinlass und einen Auslass für die Saugluft aufweist, wobei die Ansaugöffnung des Sauggebläses im oberen Teil des Kehrichtbehälters nach oben gerichtet montiert ist.The invention relates to a street sweeper with a suction fan, a suction nozzle and a refuse container, which has a refuse inlet connected to the suction nozzle and an outlet for the suction air, the suction opening of the suction fan being mounted upward in the upper part of the refuse container.
Bei Strassenkehrmaschinen dieses Typs ist das Problem bekannt, dass die Trennung des angesaugten Kehrichts von der wieder ausgestossenen Saugluft ungenügend ist. Auch ist die Lärmabschirmung von Gebläse und Motor bisher unbefriedigend. Eine bekannte Lösung gemäss EP-B1 0 327 483 (Mathieu Sofraflor) bringt eine Saugeinrichtung für eine selbstfahrende Strassenkehrmaschine mit einem Chassis, einer Saugturbine und einem Sammelbehälter für den angesaugten Kehricht. Dabei ist die Saugturbine mit einer vertikalen Achse oberhalb des Sammelbehälters an einem beweglichen Deckel montiert. Dieser Deckel ist mit einer Wand des Sammelbehälters über ein elastisches Glied verbunden.In street sweepers of this type, the problem is known that the separation of the suctioned refuse from the suction air that is expelled again is insufficient. The noise shielding of the blower and motor has also been unsatisfactory to date. A known solution according to EP-B1 0 327 483 (Mathieu Sofraflor) provides a suction device for a self-propelled street sweeper with a chassis, a suction turbine and a collecting container for the suctioned rubbish. The suction turbine is mounted on a movable cover with a vertical axis above the collecting container. This lid is connected to a wall of the collecting container via an elastic member.
Zum Stand der Technik gehört ferner gemäss CH-A5 678 342 (Konrad Peter) eine Strassenkehrmaschine mit mindestens einer Saugdüse, einem Kehrichtbehälter, einer Saugvorrichtung sowie einer Flüssigkeitsleitung, um Flüssigkeit aus dem Kehrichtbehälter in den Bereich der Saugdüse zu leiten und ein Binden des Staubes an die Flüssigkeit zu erwirken. In der Flüssigkeitsleitung ist ein Schliessorgan angeordnet, welches nur bei vorhandenem Saugluftstrom öffnet.According to CH-A5 678 342 (Konrad Peter), the state of the art also includes a street sweeper with at least one suction nozzle, a waste container, a suction device and a liquid line for guiding liquid from the waste container into the area of the suction nozzle and binding the dust to obtain the liquid. A closing element is arranged in the liquid line, which opens only when there is a suction air stream.
Weiterhin wurde gemäss DE-29 08 008 A1 (Kibo) vorgeschlagen, ein Fahrzeug der eingangs genannter Art zum Reinigen von Strassen, Verkehrsflächen und dergleichen so auszubilden, dass weitgehend unabhängig von der Form eines Sammelbehälters und mit einem Minimum an baulichem Aufwand eine einwandfreie und wirksame Trennung von Luft- und Schmutzteilchen erfolgt. Diese Aufgabe wurde bei einem derartigen Fahrzeug mit einem auf dem Fahrgestell angeordneten, eine aufschwenkbare Rückwand besitzenden Sammelbehälter, einem bodenseitig und in einem führerhausseitigen Eckbereich in den Behälter geführten Einwurfrohr, einem vor dem Behälter gelegenen und über einen Saugschacht mit dem Behälter verbundenen Gebläse sowie einer zwischen Saugschachtende und Behälterinnenraum vorgesehenen Filteranordnung dadurch gelöst, dass der Behälterinnenraum durch eine sich in Längsrichtung des Behälters und von der Behälterecke nach unten erstreckende Teiltrennwand in einen Einwurfbereich und in einen Absetz- und Luftabzugsbereich unterteilt ist, dass das Einwurfrohr schräg gegen die mit einer Prallblechanordnung versehene Behälterdecke im Einwurfbereich gerichtet ist, und dass die Filteranordnung grossflächig ausgebildet und an der Behälterdecke vom Einwurfbereich durch die Teiltrennwand abgeschirmt angebracht ist.Furthermore, according to DE-29 08 008 A1 (Kibo), it was proposed to design a vehicle of the type mentioned at the outset for cleaning roads, traffic areas and the like in such a way that it is largely independent of the shape of a collecting container and with a minimum of structural complexity and is flawless and effective Air and dirt particles are separated. This object was achieved in such a vehicle with a collecting container arranged on the chassis and having a swing-open rear wall, a throw-in tube guided into the container on the bottom and in a corner area on the cab, a fan located in front of the container and connected to the container via a suction shaft, and an intermediate fan The filter arrangement provided in the suction shaft end and container interior is solved in that the container interior is divided into a throw-in area and a settling and air extraction area by a partial partition wall which extends in the longitudinal direction of the container and downwards from the corner of the container, such that the throw-in tube is inclined against the container ceiling provided with a baffle plate arrangement is directed in the throw-in area, and that the filter arrangement has a large area and is attached to the container ceiling from the throw-in area and is shielded by the partial partition.
Aufgabe der vorliegenden Erfindung ist es, eine Strassenkehrmaschine zu schaffen, welche eine verbesserte Trennung des Kehrgutes von der Saugluft aufweist.The object of the present invention is to provide a street sweeper which has an improved separation of the sweepings from the suction air.
Gemäss der Erfindung wird dies bei einer Strassenkehrmaschine der eingangs genannten Art dadurch erreicht, dass die Ansaugöffnung des Sauggebläses im oberen Teil des Kehrichtbehälters mittig in Bezug auf Länge und Breite montiert ist.According to the invention, this is achieved in a street sweeper of the type mentioned at the outset in that the suction opening of the suction fan is mounted centrally in the upper part of the refuse container with respect to length and width.
Die Erfindung wird mit Vorteil so ausgeführt, dass im oberen Teil des Kehrichtbehälters im Bereich eines gegenüber der Ansaugöffnung des Sauggebläses wesentlich grösseren Querschnittes des Saugluftstromes ein Trenngitter für den Kehricht angebracht und unterhalb des Sauggebläses und dem gesammelten Kehricht zugewendet dessen Motor montiert ist.The invention is advantageously carried out in such a way that in the upper part of the refuse container, in the area of a cross section of the suction air flow that is substantially larger than the suction opening of the suction fan, a separating grid for the refuse is attached and below the suction fan and the collected waste whose motor is mounted.
Die mit der Erfindung erzielten Vorteile bestehen darin, dass eine Blockierung der Ansaugöffnung des Sauggebläses durch den Kehricht sehr erschwert ist, dass ein Teil der Abluft durch Rückführung wieder verwertbar ist und dass eine gute Lärmdämpfung erreicht wird.The advantages achieved by the invention are that blocking of the suction opening of the suction fan by the rubbish is very difficult, that part of the exhaust air can be reused by recycling and that good noise reduction is achieved.

Wie die Figur 1 zeigt, umfasst die dargestellte Strassenkehrmaschine 1 ein Fahrgestell 2, eine Fahrerkabine 3, einen auf dem Fahrgestell 2 gelagerten Kehrichtbehälter 4 und eine Saugeinrichtung 5, welche in einem Deckel 6 des Kehrichtbehälters 4 montiert ist. Der Kehrichtbehälter 4 kann zur Entleerung mittels eines Lagers 7 nach hinten abgekippt werden. Der Kehricht wird mittels rotierender Bürsten 8 vor einer Saugdüse 9 am Boden 28 gesammelt und gelangt von dort mittels eines Rohres 10 in den Kehrichtbehälter 4, wo er mittels eines Umlenkbleches 11 zum Behälterboden hin gerichtet wird.As shown in FIG. 1, the
Wie die Fig. 2 zeigt, besitzt der Kehrichtbehälter 4 einen Boden 12, in welchem sich der vom Rohr 10 her kommende Kehricht 13 sammelt. Der Deckel 6 des Kehrichtbehälters 4 ist an Scharnieren 14 aufklappbar. Die Saugeinrichtung 5 umfasst ein Sauggebläse 15, welches im Deckel 6 etwa in dessen Mitte montiert ist. Die Ansaugöffnung 16 des Sauggebläses 15 ist vom Kehrichteinlass 17 des Rohres 10 und vom im Boden 12 gesammelten Kehricht 18 abgewendet und nach oben gerichtet.As shown in FIG. 2, the
Diese Anordnung der Ansaugöffnung 16 hat wesentliche Vorteile. Das Sauggebläse 15 kann die Luft aus dem Kehrichtbehälter 4 von allen Seiten her ansaugen und hat daher eine optimale Wirkung. Der Querschnitt des Saugluftstromes, welcher aus dem Kehrichtbehälter 4 von unten um das Sauggebläse 15 herum zur Ansaugöffnung 16 gelangt, ist also im oberen Teil des Kehrichtbehälters 4 und vor Erreichen der Ansaugöffnung 16 wesentlich grösser, als der Querschnitt der Ansaugöffnung 16.This arrangement of the suction opening 16 has significant advantages. The
Die Draufsicht gemäss Figuren 2 und 3 zeigt, dass in Höhe der Ansaugöffnung 16 des Sauggebläses 15 und um diese Ansaugöffnung herum ein Trenngitter 19 zum Zurückhalten des Kehrichts montiert ist. Im Bereich dieses grossen Saugluftquerschnittes ist infolge der geringeren Luftgeschwindigkeit das Mitreissen von Kehricht reduziert, sodass eine Blockierung des Trenngitters 19 wenig wahrscheinlich ist. Der Saugluftstrom weist um das Sauggebläse 15 herum eine homogene Geschwindigkeits-Verteilung auf, Geschwindigkeits- Spitzen, welche ein Mitreissen von Kehricht bewirken könnten, treten hier nicht auf.The top view according to FIGS. 2 and 3 shows that at the level of the suction opening 16 of the
Ausserdem ist infolge der Anordnung des Trenngitters 19 oberhalb des Sauggebläses 15 der Weg bis zum Kehricht 13 lang, sodass leichtes Material wie Papier, Blätter usw. nicht bis zum Trenngitter 19 aufsteigen. Wie aus Fig. 2 ersichtlich, ist ein Antriebsmotor 20 des Sauggebläses 15 unterhalb desselben und innerhalb des Kehrichtbehälters 4 montiert. Damit wird oberhalb des Kehrichtbehälters 4 kein Montageraum benötigt, und der Kehrichtbehälter 4 nebst dem darin angesammelten Kehricht bewirken eine wesentlich verbesserte Lärmdämpfung.In addition, due to the arrangement of the separating
Fig. 4 zeigt eine vorteilhafte Ausgestaltung der Luft- Zu- und Abführung zum Kehrichtbehälter 4 mittels des Rohres 10. Am Auslass 21 des Sauggebläses 15 ist ein Knierohr 22 angeschlossen, in welchem eine bewegliche Klappe 23 montiert ist. Diese Klappe 23 ist auf einer Achse 24 einstellbar gelagert und bewirkt über eine Öffnung 25 im Knierohr 22 einen Auslass der Abluft von vorzugsweise zwischen 25 % und 100 %. Der restliche Teil der Abluft zwischen 75 % und 0 % ist über ein Abführrohr 26 zu einer die Saugdüse 9 (vgl. Fig. 1) umfassenden Baueinheit 27 am Boden 28 geführt.Fig. 4 shows an advantageous embodiment of the air supply and discharge to the
Dieser durch das Abführrohr 26 rückgeführte Abluft- Anteil wird in der Baueinheit 27 verwendet, um die Aufnahmewirkung für den Kehricht, z.B. in Form von Staub, zu verbessern. Bei der Aufnahme leichten Materiales, wie Papier, Blätter usw. wird mittels der Klappe 23 die Öffnung 25 im Knierohr 22 ganz geöffnet. Es wird nun keine Luft rückgeführt, und die Saugdüse 9 kann angehoben werden, ohne den Kehricht zu zerstreuen, wie es z.B. bei Aufnahme grosser Mengen von Blättern erforderlich ist.This portion of the exhaust air which is returned through the discharge pipe 26 is used in the
