The present invention relates to a sewage prevention device for a garbage collection vehicle that can prevent water pollution from occurring.

(Prior Art) Generally, a garbage collection vehicle has a garbage storage box opened at the rear mounted on the vehicle body, and a tailgate having a built-in loading device is attached to the rear opening of the garbage storage box. An inner cylindrical groove-shaped sump is provided below the tailgate to temporarily collect thrown-in garbage. The garbage thrown into this sump is scooped up by a rotating plate that is rotated by a rotating shaft installed laterally, and then by a pushing plate that swings forward about a pivot shaft. It is designed to be pushed into a garbage storage box. With this type of equipment, there are health and safety issues such as sewage scattering when compressing and pushing the garbage into the storage box, or debris scattering outside from the inlet and causing injury to workers. Ta.
In particular, if a glass bottle mixed in the garbage is caught between the tip of the pushing plate and the rotary plate and shattered, the glass fragments will fly backwards, making it even more dangerous.

In order to prevent this, it has conventionally been done to close the gap between the rotary plate and the tip of the pusher plate by fixing a rubber plate to the back surface near the lower end of the pusher plate.

(Problems to be solved by the invention) However, during long-term use, the rubber plate easily gets caught in the tip of the pushing plate and gets damaged, and as a result, the rubber plate has to be replaced frequently. It was hot.

Therefore, the purpose of the present invention is to provide a sewage scattering prevention device for a garbage collection vehicle that can prevent the sewage and debris generated when the pushing plate pushes the garbage from scattering to the outside, and has a long service life. be.

(Means for Solving the Problems) Therefore, in order to achieve the above object, the present invention has a rotating plate that scoops up the garbage thrown into the sump while rotating, and a rotary plate that swings back and forth around the center of swing. In the garbage collection vehicle equipped with a push plate for pushing the garbage scooped up onto the rotary plate into the garbage storage box, one end of the swing link is pivotally supported inside both side plates of the tailgate, and these A scattering prevention plate that can cover the rear of the rotary plate is installed vertically at the free end of the swing link, and a link connects the middle part of the swing link and the back part above the swing center of the push plate. It is characterized by being connected by.

(Function) In synchronization with the pushing plate reciprocating angularly back and forth around the swinging center, the swinging link, which is partially pivoted on the side plate of the tailgate, moves reciprocatingly around the pivot point, and its tip A scattering prevention plate installed vertically covers the rear of the rotary plate to prevent sewage and dust particles from scattering.

(Example) Hereinafter, an example of the sewage scattering prevention device for a garbage collection vehicle according to the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 indicates a part of the garbage storage box, and a tailgate 3 equipped with a garbage inlet 2 is integrally attached to the rear opening of the garbage storage box 1. A sump 4 is provided below the sump 4 for temporarily storing the garbage inputted from the input port 2. This sump 4 has the form of an inner cylindrical receiving groove, and the left edge of the sump 4 in the figure is connected to the floor surface of the garbage storage box 1, while the right edge of the sump 4 in the figure is a garbage inlet. It is connected to a horizontal frame 5 which forms the lower edge of 2.

A rotating shaft 6 is installed in the space above the sump 4 along the lateral direction, and the rotating shaft 6 is rotatably driven by a drive means such as a hydraulic motor (not shown). A rotating plate 7 is fixed to the rotating shaft 6, and a curved scooping surface 8 scoops up dirt accumulated in the sump 4.

On the other hand, a hinge shaft 9 parallel to the rotary shaft 6 is installed in the tailgate 3 above the rotary plate 7, and a push plate 10 is swingably supported on the hinge shaft 9. The tip of the pushing plate 10 extends downward and terminates at a position close to the rake face 8 of the rotary plate 7. The operating end of a piston rod 12 of a one-sided rod type hydraulic cylinder device 11 is connected to the upper end of the pushing plate 10 by a pin 13, while the base end of the hydraulic cylinder device 11 is connected to a bracket 16 of a cross beam 15. It is pivotally connected by a pin 17 to. Therefore, by expanding and contracting the piston rod 12 connected to the piston in the cylinder of the hydraulic cylinder device 11, the push plate 10 can be swung about the hinge shaft 9.

Additionally, a deflector 18 is attached to the bracket 16.
The upper end of the box 1 is fixed by a pin 19 to prevent the trash loaded into the trash storage box 1 from being pushed out backwards.

The tailgate 3 includes a pair of left and right side plates 20, 20, and the upper end of a swing link 21 is pivotally supported inside each side plate 20 via a pivot 22. Left and right axis 22, 22
It is desirable that they be set at the same height and at the same position in the front-back direction. Further, a support shaft 23 is spanned between the free ends of the pair of swing links 21, 21. This support shaft 23
A holder 24 is rotatably supported on the holder 24, and a long piece-shaped anti-scattering plate 25 is fixedly held on the holder 24. This anti-scattering plate 25 may be a single plate spanning the entire width of the tailgate 3, or may be composed of several anti-scattering plates covering the entire width. Moreover, it is preferable that the scattering prevention plate 25 is made of rubber.

On the other hand, a tab 2 is provided on the back side of the push plate 10.
6 and 26 are fixed in a protruding manner, and each tab 26 and the intermediate portion of the swing link 21 are pin-coupled by a connecting link 27. Therefore, the push plate 1
The swing link 21 performs a swing motion in conjunction with the swing motion of the rotation plate 8, and the scattering prevention plate 25 is held at the position immediately behind the rotary plate 8.

Next, the operation of the above-mentioned sewage scattering prevention device for the garbage collection vehicle will be explained.

The garbage to be collected is put into the sump 4 and is temporarily stored therein. When the rotary plate 7 begins to be rotated clockwise by the hydraulic motor from the position shown by the solid line in FIG. Due to the contraction of the piston rod 12 of the cylinder device 11, it moves backward in the counterclockwise direction,
It stops at the retreat position C in FIG. During this time, the rotary plate 7 continues to rotate clockwise, scooping up dust on the way, and stopping again at the push-in position shown by the solid line in FIG. 1.

Next, the piston rod 12 of the hydraulic cylinder device 11 is extended to swing the pushing plate 10 from the retracted position C to the pushing plate A, and the dirt on the rake face 8 of the rotary plate 7 is pushed into the dirt storage chamber. During this time, the swing link 21 swings between the a position and the c position,
Along with this, the scattering prevention plate 25 moves between the a' position and the c' position while maintaining a vertical posture. Therefore, the dust is pushed onto the rake surface 8 of the rotary plate 7 and the plate 10
While pushing forward, the scattering prevention plate 25 is held at position a', and can effectively prevent sewage and dust particles from scattering backward.

[Effect of idea]

As is clear from the above explanation, according to the present invention, the swinging link is driven in conjunction with the swinging movement of the pushing plate between the pushing position and the retreating position, and the scattering prevention plate is suspended from the tip of the swinging link. Since the anti-scattering plate is provided, the anti-scattering plate can be held in a hanging state behind the rotating plate without the anti-scattering plate interfering with the rotating plate. Therefore, when the pushing plate moves on the rake surface of the rotary plate and pushes the garbage into the storage chamber, the sewage and dust particles that are scattered are reliably caught by the scattering prevention plate, effectively preventing them from scattering backwards. can be prevented.
