Description

[Detailed description of the invention] This invention relates to a garbage loading device for a garbage collection vehicle.

In general, various kinds of garbage piled up in built-up areas such as urban areas are collected in cleaning containers or garbage containers, and then a worker lifts the cleaning container and dumps only the garbage from the input port of a garbage truck into a box. Alternatively, as shown in FIG. 1, the cleaning container or garbage container 1 is lifted by a crane truck 2 and transferred to a dump truck or garbage collection truck 3 for transportation. However, in recent years, the amount of such garbage has been increasing more and more, and the cleaning container 1 that accommodates it has naturally become larger in size so that it can accommodate a large amount of garbage. Therefore, the weight of the cleaning container 1 that accommodates such a large amount of garbage becomes excessive, which is dangerous, and since the garbage stored in the cleaning container 1 is of various types, the garbage collection vehicle 3, etc. It was very difficult to handle and the workers involved were extremely fatigued. or,
When transferring trash, the trash scatters onto the road, seriously impeding the surrounding environmental hygiene, making it impossible to carry out smooth loading operations, and requiring excessive effort.

Furthermore, there is currently known a garbage loading device for a garbage truck, as shown in FIG. 2, in which a crane 6 is directly mounted on the main frame 5 at the front of the garbage storage box 4 of the garbage truck 3. That is, this type of garbage loading device for a garbage collection vehicle operates the operating lever 6a of the crane 6 when transferring the cleaning container 1 shown in FIG. Clean the hook part 6b with the wire 1a of the container 1.
At the same time, the boom section 6c of the crane 6 is rotated to remove the rear loading box 7.
The cleaning container 1 is stopped above and lowered to the vicinity of the input port 7a of the garbage input box 7, and at the same time the garbage potper 8 is opened to input the garbage. Therefore, due to the presence of the crane 6 that directly loads the garbage loaded into the cleaning container 1 onto the garbage collection vehicle 3, the cleaning container 1 can be lifted and transferred as appropriate, thereby saving the labor involved. , it is possible to carry out smooth loading work, which leads to improvement of work efficiency, but since the crane 6 is mounted on the front part of the garbage storage box 4 of the garbage collection vehicle 3, the garbage dumper 8 of the garbage input box 7 is The boom portion 6b of the crane 6 must be extended to an appropriate position, resulting in a long stroke, making the device bulky and heavy, which is disadvantageous in terms of load weight limitations. In addition, the above conventional garbage collection vehicle
As described above, since the crane 6 is mounted on the main frame 5 at the front of the storage box 4, the installation space of the garbage storage box 4 is limited and the garbage loading capacity is reduced, and the crane 6 is The operating lever 6a is also connected to the crane 6 on the front side of the storage box 4.
Since the crane 6 is installed integrally with the crane 6, it is extremely difficult for the operator operating the crane 6 to operate the crane 6 while checking the work situation at the rear during the work. This was undesirable because it led to the danger of injury and decreased work efficiency.

Therefore, this invention is an improvement on the conventional garbage loading device of the garbage collection vehicle in view of the above-mentioned drawbacks, and a lightweight and compact garbage loading device is installed near the garbage potper of the garbage collection vehicle. Another object of the present invention is to provide a garbage loading device for a garbage collection vehicle that can appropriately accommodate a large amount of garbage and improve work safety and work efficiency.

The cylinder 22 is a stopper provided at a predetermined position of the garbage disposal box 15. That is, the rotary plate 17 scrapes up the garbage thrown in from the input port 15a of the garbage input box 15, and at the same time, the cylinder 20 is moved to expand and contract, and the garbage scraped up by the rotary plate 17 is pushed into the plate. Garbage storage box 1 by 18
It is configured so that it can be pushed into the Then, when discharging garbage, etc., the cylinder 20 is extended,
When the upper end of the push plate 18 is brought into contact with the stopper 22 and the cylinder 20 is further extended, the garbage input box 15 is opened using the shaft 16a of the bracket 16 as a fulcrum. On the other hand, a drive cylinder 23 is pivotally mounted and held in front of the bottom surface of the garbage storage box 13, and a push-out plate 24 is attached to the tip of the piston rod 23a of the drive cylinder 23, and is held slidably in the front-rear direction. I'm letting you do it. This extrusion plate 24 is made up of a vertical piece 24a that also serves as the front wall of the garbage storage box 13, and a scooping piece 24b extending diagonally downward from the vertical piece 24a. is being discharged. The above points are similar to the configuration of conventional garbage collection vehicles.
