Definitions
- the invention relates to a material feed container for a slurry pump according to the preamble of claim 1.
- a material feed container for thick matter pumps which has an upwardly open container bottom part and a container attachment releasably connected thereto via a flange connection.
- the peripheral upper edge of the container attachment limits the material feed opening.
- an agitator is mounted, the bearings are in an open-edged recess of the container base, so that the agitator is easily replaceable after removal of the container attachment.
- the container attachment forms a hopper for thick matter, such as concrete.
- the filling of the concrete is usually carried out in that a truck mixer approaches the material supply container and fills the concrete via a channel in the material supply container.
- the container attachment must be made of sturdy sheet metal. This requires a high weight, so that the container attachment can not be easily removed by hand.
- Material feed container according to EP 1 076 596 B1 have in the delivery cylinder openings intermediate rings as wearing parts that protect the belonging to the container end wall inner surface of the delivery cylinder opening from wear by flowing concrete. These intermediate rings must be replaced regularly due to wear. Since the intermediate rings are inserted from the delivery cylinder side into the delivery cylinder opening, the delivery cylinder must first be removed from the container end wall for mounting and dismounting. This is expensive.
- a material supply container having the features of the preamble of claim 1 is known. It has a hinged lid for covering the material feed opening.
- a vehicle engine cover which has a hinged hood with a cover part made of a plastic wall.
- a tiltable engine cover for trucks which consists of glass fiber reinforced plastic.
- the engine cowling has glued-on reinforcing ribs on its inside.
- the solution according to the invention is based on the idea that a hinged lid covering the material feed opening and articulated on a container wall is easier to clean than a conventional hinged lid made of sheet metal. Thick material, especially concrete, adheres much less to plastic than to sheet metal.
- the hinged lid is designed as a hollow plastic body with a first plastic shell facing the material feed opening and a second plastic shell which preferably integrally connects to the latter and forms a top side of the lid.
- a plastic hollow body is relatively stable with low weight. This is particularly advantageous when the hinged lid is hinged to the container attachment and must be removed together with the container attachment for maintenance work inside the container.
- the first plastic shell may have a smooth surface facing the material supply opening.
- the second plastic shell has stiffening beads. This gives the hinged lid increased stability.
- the hinged lid is advantageously made in one piece by a Rotationsg tell Kunststoff.
- the hinged lid expediently has handles, which are preferably integrally formed. Furthermore, it expediently has hooks, in which fastened to a container wall closure elements can be hooked. The hooks are preferably integrally formed on the hinged lid.
- the hinged lid is preferably connected by at least one hinge and at least one gas spring with the container end wall. The gas spring facilitates the opening of the lid. Near its side connected to the container end wall, the hinged lid on the first plastic shell expedient attachment means for a rubber apron. This hangs down from the hinged lid into the material feed opening and prevents thick material from flowing into the gap between the hinged lid and the container end wall.
- the advantageous development according to claim 9 is based on the idea that it requires less effort to mount the intermediate rings on the inside of the container and dismantle as over the container outside. This avoids that when replacing the intermediate rings, the delivery cylinder must be disconnected from the material supply container. An intermediate ring is inserted over the container interior into the delivery cylinder opening by the cam is pushed on its outer surface in the bayonet opening and the intermediate ring is then rotated about its longitudinal axis, so that the cam is inserted into the inner groove.
- the mounting of an intermediate ring on the container interior is particularly advantageous when the material feed container, as described above, is formed in two parts. By removing the relatively light container top the inside of the container is easily accessible.
- the advantageous development according to claim 15 is based on the idea to make the interior of the material feed container for maintenance personnel easier to access by having an easily demountable and removable container attachment on the end wall side.
- the container top does not extend to the rear wall which faces the approaching truck mixer.
- the peripheral edge delimiting the material feed opening has, on the rear wall side, an edge part belonging to the container lower part.
- the container attachment is thus protected against damage by the truck mixer. It must therefore not be designed as stable as the container base and can have a relatively low weight.
- Fig. 1 shown in the drive state truck concrete pump has a chassis 10, a front-side cab 12, a mounted on a pivot bracket 14 of the chassis 10 concrete distribution boom 16 and arranged on the chassis 10 two-cylinder slurry pump 18.

- the container lower part 38 has, in addition to a bottom 54 and the rear wall 28, a lower end wall portion 56 and lower side wall portions 58.
- the lower side wall portions 58 drop obliquely from the lower end wall portion 56 and carry a second flange 60 complementary to the first flange 50.
- the two flanges 50, 60 are connected in a simple manner by means of screws 62. Between them, a rubber seal can be arranged so that the container base 38 and container attachment 40 can be assembled in a simple manner to the material supply container 20.
- the material supply container 20 has an upwardly facing material feed opening 64, which is delimited by a peripheral edge 66, 68.
- the peripheral edge is divided into two edge parts 66, 68.
- the first edge portion 66 is formed by the upper edge of the upper end wall portion 44 and the upper side wall portions 46. It is followed by the second edge part 68, which is formed by the upper edge of a rubber apron 70.

Description
Die Erfindung betrifft einen Materialaufgabebehälter für eine Dickstoffpumpe gemäß Oberbegriff des Anspruchs 1.The invention relates to a material feed container for a slurry pump according to the preamble of

Aus der
Es ist Aufgabe der Erfindung, einen Materialaufgabebehälter der eingangs genannten Art derart weiterzubilden, dass er einfacher zu warten ist und dass Verschleißteile einfacher ausgetauscht werden können.It is an object of the invention to develop a material supply container of the type mentioned in such a way that it is easier to maintain and that wearing parts can be replaced easily.
Die Aufgabe wird durch einen Materialaufgabebehälter mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved by a material supply container having the features of
Der erfindungsgemäßen Lösung liegt der Gedanke zugrunde, dass ein die Materialzuführöffnung abdeckender, an einer Behälterwand angelenkter Klappdeckel aus Kunststoff einfacher zu reinigen ist als ein herkömmlicher Klappdeckel aus Blech. Dickstoff, insbesondere Beton, haftet wesentlich schlechter an Kunststoff als an Blech. Der Klappdeckel ist als Kunststoffhohlkörper mit einer der Materialzuführöffnung zugewandten ersten Kunststoffschale und einer mit dieser vorzugsweise einstückig verbundenen, eine Deckeloberseite bildenden zweiten Kunststoffschale ausgebildet. Ein Kunststoffhohlkörper ist bei geringem Gewicht relativ stabil. Dies ist insbesondere dann vorteilhaft, wenn der Klappdeckel am Behälteraufsatz angelenkt ist und für Wartungsarbeiten im Behälterinneren gemeinsam mit dem Behälteraufsatz abgenommen werden muß.The solution according to the invention is based on the idea that a hinged lid covering the material feed opening and articulated on a container wall is easier to clean than a conventional hinged lid made of sheet metal. Thick material, especially concrete, adheres much less to plastic than to sheet metal. The hinged lid is designed as a hollow plastic body with a first plastic shell facing the material feed opening and a second plastic shell which preferably integrally connects to the latter and forms a top side of the lid. A plastic hollow body is relatively stable with low weight. This is particularly advantageous when the hinged lid is hinged to the container attachment and must be removed together with the container attachment for maintenance work inside the container.
Um eine Reinigung zu erleichtern, kann die erste Kunststoffschale eine der Materialzuführöffnung zugewandte glatte Oberfläche aufweisen. Demgegenüber wird bevorzugt, dass die zweite Kunststoffschale Versteifungssicken aufweist. Dies verleiht dem Klappdeckel eine erhöhte Stabilität. Der Klappdeckel ist vorteilhafterweise durch ein Rotationsgießverfahren einstückig hergestellt.To facilitate cleaning, the first plastic shell may have a smooth surface facing the material supply opening. In contrast, it is preferred that the second plastic shell has stiffening beads. This gives the hinged lid increased stability. The hinged lid is advantageously made in one piece by a Rotationsgießverfahren.
Der Klappdeckel weist zweckmäßig Handgriffe auf, die vorzugsweise einstückig angeformt sind. Desweiteren weist er zweckmäßig Haken auf, in die an einer Behälterwand befestigte Verschlusselemente eingehakt werden können. Auch die Haken sind vorzugsweise einstückig am Klappdeckel angeformt. Der Klappdeckel ist vorzugsweise durch mindestens ein Scharnier und mindestens eine Gasfeder mit der Behälterstirnwand verbunden. Die Gasfeder erleichtert das Öffnen des Deckels. Nahe seiner mit der Behälterstirnwand verbundenen Seite weist der Klappdeckel an der ersten Kunststoffschale zweckmäßig Befestigungsmittel für eine Gummischürze auf. Diese hängt vom Klappdeckel herunter in die Materialzuführöffnung hinein und verhindert, dass Dickstoff in den Spalt zwischen dem Klappdeckel und der Behälterstirnwand fließt.The hinged lid expediently has handles, which are preferably integrally formed. Furthermore, it expediently has hooks, in which fastened to a container wall closure elements can be hooked. The hooks are preferably integrally formed on the hinged lid. The hinged lid is preferably connected by at least one hinge and at least one gas spring with the container end wall. The gas spring facilitates the opening of the lid. Near its side connected to the container end wall, the hinged lid on the first plastic shell expedient attachment means for a rubber apron. This hangs down from the hinged lid into the material feed opening and prevents thick material from flowing into the gap between the hinged lid and the container end wall.
Der vorteilhaften Weiterbildung gemäß Anspruch 9 liegt der Gedanke zugrunde, dass es weniger Aufwand erfordert, die Zwischenringe über die Behälterinnenseite zu montieren und zu demontieren als über die Behälteraußenseite. Dadurch wird vermieden, dass bei einem Austausch der Zwischenringe die Förderzylinder vom Materialaufgabebehälter abgekoppelt werden müssen. Ein Zwischenring wird über das Behälterinnere in die Förderzylinderöffnung eingesetzt, indem der Nocken an seiner äußeren Mantelfläche in die Bajonettöffnung geschoben wird und der Zwischenring anschließend um seine Längsachse verdreht wird, so dass der Nocken in die Innennut eingeführt wird. Die Montage eines Zwischenrings über das Behälterinnere ist besonders dann vorteilhaft, wenn der Materialaufgabebehälter, wie oben beschrieben, zweiteilig ausgebildet ist. Durch Entfernen des relativ leichten Behälteraufsatzes ist das Behälterinnere gut zugänglich.The advantageous development according to claim 9 is based on the idea that it requires less effort to mount the intermediate rings on the inside of the container and dismantle as over the container outside. This avoids that when replacing the intermediate rings, the delivery cylinder must be disconnected from the material supply container. An intermediate ring is inserted over the container interior into the delivery cylinder opening by the cam is pushed on its outer surface in the bayonet opening and the intermediate ring is then rotated about its longitudinal axis, so that the cam is inserted into the inner groove. The mounting of an intermediate ring on the container interior is particularly advantageous when the material feed container, as described above, is formed in two parts. By removing the relatively light container top the inside of the container is easily accessible.
Der vorteilhaften Weiterbildung gemäß Anspruch 15 liegt der Gedanke zugrunde, das Innere des Materialaufgabebehälters für Wartungspersonal leichter zugänglich zu machen, indem er stirnwandseitig einen leicht demontierbaren und abnehmbaren Behälteraufsatz aufweist. Der Behälteraufsatz erstreckt sich jedoch nicht auf die Rückwand, die dem anfahrenden Fahrmischer zugewandt ist. So weist der die Materialzuführöffnung begrenzende umlaufende Rand rückwandseitig eine zum Behälterunterteil gehörende Randpartie auf. Der Behälteraufsatz ist so vor Beschädigungen durch den Fahrmischer geschützt. Er muß daher nicht so stabil ausgebildet sein wie das Behälterunterteil und kann ein relativ geringes Gewicht aufweisen.The advantageous development according to claim 15 is based on the idea to make the interior of the material feed container for maintenance personnel easier to access by having an easily demountable and removable container attachment on the end wall side. However, the container top does not extend to the rear wall which faces the approaching truck mixer. Thus, the peripheral edge delimiting the material feed opening has, on the rear wall side, an edge part belonging to the container lower part. The container attachment is thus protected against damage by the truck mixer. It must therefore not be designed as stable as the container base and can have a relatively low weight.

Das Behälterunterteil 38 weist neben einem Boden 54 und der Rückwand 28 eine untere Stirnwandpartie 56 sowie untere Seitenwandpartien 58 auf. Die unteren Seitenwandpartien 58 fallen zur unteren Stirnwandpartie 56 schräg ab und tragen einen zum ersten Flansch 50 komplementären zweiten Flansch 60. Die beiden Flansche 50, 60 sind mittels Schrauben 62 auf einfache Weise verbindbar. Zwischen ihnen kann eine Gummidichtung angeordnet werden, so dass Behälterunterteil 38 und Behälteraufsatz 40 auf einfache Weise zum Materialaufgabebehälter 20 zusammengefügt werden können.The container
Der Materialaufgabebehälter 20 weist eine nach oben weisende Materialzuführöffnung 64 auf, die von einem umlaufenden Rand 66, 68 begrenzt wird. Der umlaufende Rand ist in zwei Randpartien 66, 68 unterteilt. Die erste Randpartie 66 wird durch die Oberkante der oberen Stirnwandpartie 44 und der oberen Seitenwandpartien 46 gebildet. An sie schließt sich die zweite Randpartie 68 an, die von der oberen Kante einer Gummischürze 70 gebildet wird. Diese ist am Behälterunterteil 38 befestigt und ragt über die Rückwand 28 und sich von der Rückwand 28 weg erstreckende Abschnitte der unteren Seitenwandpartien 58 hinaus. Die beiden Randpartien 66, 68 fluchten zueinander.The
Im Behälterunterteil 38 sind in den Seitenwänden 42 Lageröffnungen 72 angeordnet, die der Aufnahme von Lagern eines Rührwerks dienen.

Zum Austauschen des Zwischenrings 86 wird zunächst die Brillenplatte 82 abgeschraubt. Anschließend wird der Zwischenring 86 um seine Längsachse gedreht, bis die Nocken 92 aus den Bajonettöffnungen 95 gezogen werden können. Zu diesem Zweck weist der Zwischenring an seiner Stirnfläche Ausnehmungen 100 zum Einstecken von Haltedornen auf. Zwischen dem Zwischenring 86 und der Stirnwand 22 ist zudem ein umlaufender Hohlraum 102 angeordnet, der über eine Zuführöffnung 104 mit Fett befüllbar ist. Der Hohlraum 102 vergrößert sich beim Herausziehen des Zwischenrings 86 aus der Förderzylinderöffnung 24 in Richtung zum Behälterinneren. Dadurch erleichtert das Einpressen von Fett durch die Zuführöffnung 104 die Entnahme des Zwischenrings 86. Das Fett wirkt zudem als Schmiermittel, das das Drehen des Zwischenrings 86 erleichtert. In der Regel werden die Verschleißteile Brillenplatte 82 und Zwischenring 86 gemeinsam ausgetauscht.To replace the
