Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a garbage loading device for a garbage collection vehicle.

(Prior art) Some conventional garbage collection vehicles have a single pushing plate in the garbage input box, and the garbage is compressed and crushed by reciprocating and rotating operations (for example, Japanese Patent Laid-Open No. 52
−101522).

(Problem to be solved by the invention) In a conventional garbage collection vehicle, after crushing the garbage with the pushing plate, when pushing the garbage into the garbage storage box, there is a gap between the front inclined surface of the flat bottom of the dumping box and the tip of the rising pushing plate. It was easy for flat debris such as cardboard to get stuck in it.

(Means for Solving the Problems) The present invention solves the above-mentioned problems by connecting a garbage disposal box with an open front end face to the rear of a refuse storage box with an open rear end face, and inserting the waste into the refuse disposal box. A pushing plate for storing garbage in a garbage storage box is provided, and a plurality of protrusions extending in the vertical direction are formed on either the bottom surface of the garbage input box or the pushing plate, and the protruding stripes are formed on the other side. This is a garbage loading device for a garbage collection vehicle, which is formed with a groove that fits into the groove.

(Function) Garbage such as cardboard thrown into the garbage input box is compressed as the pushing plate descends, and is further crushed by the forward rotation of the pushing plate. Here, even if there is a flat part left on the cardboard, the push plate will rise due to the engagement of the concave strip at its tip with the convex strip on the front slope of the bottom of the input box, so each fitting portion The flat part of the cardboard is bent around the center and pushed into the garbage storage box without getting caught.

(Example) To explain an example of the present invention below, a garbage storage box 1 with an open rear end is mounted on the frame of a garbage collection vehicle, and a garbage storage box 1 with an open front end is mounted on the rear end of the garbage storage box 1. The garbage input box 2 is arranged in a tiltable manner, and the garbage storage box 1 and the garbage input box 2 are communicated with each other.

An input port 3 is opened at the rear of the garbage input box 2, and a downwardly concave arc-shaped bottom surface 4 is formed at the bottom of the garbage input box 2, and a guide groove slanting backward is formed in the side wall 2a. 6 is formed.

By the way, the garbage loading box 2 houses a garbage loading device 5 that compresses, crushes, and pushes the garbage into the garbage storage box 1.This garbage loading device 5 will be explained below. , slider 8
A roller 7 that can freely roll along a guide groove 6 is pivotally supported on both upper and lower ends of the garbage input box 2.
An elevating cylinder 9 is disposed between the bottom of the outer wall 2a and the slider 8, and by expanding and contracting the elevating cylinder 9, the slider 8 can be moved up and down along the guide groove 6.

Furthermore, a push plate 10 is provided at the lower end of the slider 8.
is rotatably supported on a shaft 11, and a push cylinder 12 is disposed between the slider 8 and the push plate 10, and when the push cylinder 12 is expanded and contracted,
The pushing plate 10 swings back and forth.

A plurality of protruding stripes 13 are fixed in the vertical direction to the front inclined surface of the bottom surface 4 of the garbage disposal box 2, and scattering prevention plates 14 fixed to the tip and tip of the push plate 10 are fixed to the front inclined surface of the bottom surface 4. , recessed portions 15 that fit with the protruding portions 13 are formed at a plurality of locations.

In addition, 16 is a shielding plate fixed to the front surface of the garbage input box 2 to prevent the garbage from returning, and 17 is a projection provided on the pressing surface of the pushing plate 10, which crushes the garbage. In addition to compressing the dust while moving, the protrusion 17 also prevents the dust from returning when the pushing plate is turned over.

That is, the pushing plate 10 in the position shown by the solid line in FIG. 1 is reversed when the pushing cylinder 12 is contracted (dotted chain line in FIG. 1). After that, when the elevating cylinder 9 is contracted, the slider 8 is lowered and the garbage in the garbage input box 2 is compressed by the pushing plate 10.
(Double-dot chain line in FIG. 1), and when the pushing cylinder 12 is further extended, the garbage is crushed (solid line in FIG. 2).

Thereafter, when the lifting cylinder 9 is extended, the slider 8 rises and pushes the garbage into the garbage storage chamber 1, completing one stroke of work.

(Effects of the invention) As described above, according to the invention, since the gap between the bottom surface and the tip of the pushing plate is formed in an uneven pattern, when pushing garbage such as cardboard into the garbage storage box, the cardboard is inserted into the gap. There is no risk of the garbage being caught, and it is possible to prevent malfunctions of the garbage loading device caused by cardboard or the like being caught.
