Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reversing device for a garbage truck, which inverts a dust container and throws the dust in the dust container into a dust throwing box.

[0002]

2. Description of the Related Art In recent years, a method has been practiced in which a dedicated garbage container is installed in a factory or a home in advance, and the entire trash container is carried out to a garbage station. And
Garbage collection workers circulate each garbage station with a garbage truck and invert the accumulated garbage containers while lifting them upward by the reversing device of the garbage truck, so that the garbage in the garbage container is put into the input port of the garbage throwing box. We throw it in and collect garbage.

Here, in order to throw dust into the throwing port of the dust throwing box, it is necessary to fix the dust container to the reversing device, but in Japanese Patent Publication No. 55-11562, the dust truck is parallel to the ground and behind the dust truck. There has been proposed a method of tying up and reversing a garbage container with a container receiver protruding to the upper side and an upper jaw protruding above the reversing device.

[0004]

However, the above-mentioned conventional reversing device has the following problems.

Since the upper jaw located at the upper end of the reversing device is hooked on the engaging portion near the upper surface flange of the dust container, the reversing device projects above the position of the input port of the garbage truck. Therefore, when the worker throws in the dust by hand throwing without using the reversing device, the dust thrown by the hand is caught by the protruding portion of the reversing device, which causes a decrease in workability.

Further, in the reversing device, since the container receiver projects rearward of the dust truck, the entire length of the dust truck becomes longer by this amount. Therefore, in order to conform the entire length of the garbage truck to the overhang safety standard, it is necessary to shorten the length of the garbage truck itself, and as a result, the volume of the dust truck to store the dust becomes small. There is.

Further, in the above-mentioned reversing device, an out-bar type waste container, which is the most popular among large-sized waste containers, cannot be used, and there is a demand for a highly versatile device capable of using an out-bar type waste container. .
