Definitions

• 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.
• the generic illustration shows an electrically powered garbage truck.
• the garbage truck has a compaction element driven by a motor.
• 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.
• 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.
• 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, wherein these points are preferably The distance between the upper and lower edges of the pressing element is a maximum of 20%, preferably a maximum of 10%, of its height.
• the pressing element is therefore not designed with a recessed profile, but is supported and guided both at its upper and lower edges, thus significantly reducing bending forces.
• one of the two points prefferably 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• a pressing element 1 in the form of a curved press plate is provided to enable waste or other collectable material to be conveyed from the chute 12 into the collection container 7 and compressed in the process.
• 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.
• the pressing element 1 is guided at points 2 and 3 at both its lower and upper ends.
• the pressing element 1 is rotatably mounted on the rotatable disk 4.
• the pressing element 1 is rotatably connected to a rod 10, which in turn is pivoted at a pivot point 11 on a side wall 5.
• the collection container 7 is stored.
• the rod 10 is shown with a dashed line because it is located behind the side wall 5.
• a circular arc-shaped recess 6 is provided in the side wall 5.
• the compaction element 1 first passes through the first, then the second, and finally the third position.
• the collected material e.g., waste
• the material is emptied into the hopper 12.
• the compaction element 1 then moves from the third position to the first position, thus catching all the collected material.
• This movement from the first to the second position lifts the material into the collection container. Lifting it 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 outward curve of the compaction element 1 increases the container volume of the collection vehicle.
• This arrangement can be driven by an electric motor, for example, which drives disk 4.
• an electric motor for example, which drives disk 4.
• 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.
• Fig. 2 shows the same arrangement as Fig. 1 with the same positions, but from a different perspective.
