Description

Technical field

[0001] The present invention relates to a collection vehicle, in particular a waste collection vehicle, comprising an electric power source, a collection container, a loading unit, a pressing element and an electric motor that drives the pressing element. State of the art

[0002] The generic illustration shows an electrically powered garbage truck. The garbage truck has a compaction element driven by a motor. For this purpose, an articulated quadrilateral is provided, the crossbar of which is attached to the collection vehicle and from which one arm can perform full rotations. This arm is driven by the motor. The compaction element is positioned as an extension of the connecting rod, thus having a free end, which results in very high bending forces when the garbage is compacted. This is likely why the compaction element is relatively low compared to the height of the waste container; the garbage is pushed diagonally upwards into the waste container by the compaction element in a channel. Due to the arrangement of the compaction element, the waste container is relatively small and could be made larger with a more efficient design. Furthermore, the arrangement results in a relatively high loading edge, a relatively wide overhang, and protruding levers. Brief description of the invention

[0003] The aim of the present invention is to provide a collection vehicle whose pressing mechanism allows for a larger loading space, a lower loading edge, a smaller overhang and smooth walls, and whose pressing element is more stably attached.

[0004] According to the invention, this is achieved by a collecting vehicle of the type mentioned above in that the pressing element is guided and mounted at two points on both sides, these points preferably being located a maximum of 20%, and more preferably a maximum of 10%, of the height of the pressing element from its upper and lower edges, respectively. Thus, according to the invention, the pressing element is not designed to be recessed, but is guided and mounted both in the region of its upper edge and in the region of its lower edge, so that the bending forces are significantly reduced.

[0005] It is advantageous for one of the two points to be rotatably mounted on a disc driven by the electric motor. The disc guides the pressing element without the material being collected (e.g., waste) becoming jammed in the guide.

[0006] A preferred embodiment consists of the pressing element being guided along a track on a side wall at the other point. Guiding the second end of the pressing element in the side wall also prevents material from becoming jammed between the lever and the side wall. Furthermore, a track guide based on a freely selectable profile is enabled, as long as it can be implemented in the side wall. This makes it possible to trace significantly more complex profiles than just a circular arc.

[0007] Another preferred embodiment consists in the pressing element being rotatably connected at the other point to a rod that is rotatably attached to the collection vehicle at a pivot point. The rod thus guides the pressing element at its second end along a circular arc. This represents a cost-effective arrangement.

[0008] It is preferred that the pivot point is located below the other point and offset towards the collection vehicle. This arrangement allows the pressing element to be positioned so that the collection container can hold a large amount of collected material and be pressed essentially horizontally over a large area.

[0009] A particularly preferred embodiment consists in the height of the pressing element being at least 30%, preferably at least 50%, of the maximum height of the collection container of the collection vehicle. Using the entire pressing element for pressing allows for a large pressing area; this is explained in more detail in the description of the figures.

[0010] Another particularly preferred embodiment consists in the pressing element being curved. A tall / large, curved pressing element allows waste to be compressed over a large area, so that a large volume can be gained through compression in a single pressing motion. Brief description of the drawing figures

[0011] The present invention is explained in more detail with reference to the accompanying drawings. They show: Fig. 1 a side view of a pressing element of a collection vehicle in various positions; and Fig. 2 an isometric view of the pressing element from Fig. 1 in various positions. Description of the execution types

[0012] The collection vehicle has a collection container 7, in front of which (behind it in the direction of travel) is a chute 12, the loading edge 8 of which is relatively low. The chute 12 is approximately cylindrical, and on one side of it is a disc 4, which is rotatable by a motor. The axis of the disc 4 is approximately aligned with the axis of the cylindrical chute 12. To enable waste or other collectable material to be conveyed from the chute 12 into the collection container 7 and compressed in the process, a pressing element 1 in the form of a curved press plate is provided. Fig. 1 and 2 The press element 1 can be seen in three different positions; one position is shown with a solid line, the other two positions are indicated with dashed lines.

[0013] According to the invention, the pressing element 1 is guided at points 2 and 3 at both its lower and upper ends. At point 2, the pressing element 1 is rotatably mounted on the rotatable disk 4. At point 3, the pressing element 1 is rotatably connected to a rod 10, which in turn is mounted at a pivot point 11 on a side wall 5 of the collection container 7. The rod 10 is shown with dashed lines because it is located behind the side wall 5. A circular arc-shaped recess 6 is provided in the side wall 5 to allow the rod 10 to connect to the pressing element 1.

[0014] In a first position (right dashed line), point 2 of the pressing element 1 is located near the lowest point of the disk 4, and point 3 of the pressing element is at the lower end of the recess 6. In a second position (solid line), point 2 of the pressing element 1 is at mid-height, having moved towards the collecting vehicle, and point 3 of the pressing element 1 is located approximately in the middle of the recess 6. In the third position (left dashed line), point 2 of the pressing element 1 is located near the highest point of the disk 4, and point 3 of the pressing element 1 is located at the top of the recess 6. In each position, the pressing element 1 is overlaid by a cover 9.

[0015] During the compaction process, the compaction element 1 first passes through the first, then the second, and finally the third position. When the compaction element 1 is in the third position, the collected material (e.g., waste) can be loaded into the collection vehicle. The material is then emptied into the hopper 12. The compaction element 1 then moves from the third position to the first position, thus collecting all the material. This movement from the first to the second position lifts the material into the collection container. Lifting from a lower position to a higher container results in a low loading edge 8, which is particularly convenient for manual loading. The movement from the second to the third position then compresses the material through a motion that occurs primarily from back to front (front being towards the collection vehicle) and involves only a slight rotation.The outwardly curved press element 1 increases the container volume of the collection vehicle.

[0016] This arrangement can be driven by an electric motor, for example, which drives disc 4. This is particularly advantageous in an electric collection vehicle because it virtually eliminates the transmission losses that are typically present when using hydraulic cylinders.

[0017] The arrangement including disc 4 and the movement along the side wall 5 provides significantly smoother side walls than arm-guided pressing elements, thus reducing the risk of collecting material snagging / jamming on the side wall or on existing arms.

[0018] Fig. 2 shows the same arrangement as Fig. 1 with the same positions, but from a different perspective. List of reference symbols
