Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a garbage collection vehicle in which the collected garbage can be discharged from the rear opening of the body by rearward operation of a discharge plate installed in the body for storing sacred garbage.

Generally, in garbage collection vehicles that use a discharge plate to forcibly discharge the garbage stored in the body, the rail member that guides the movement of the discharge plate is provided on the side wall of the body that is higher than the floor surface of the body. .

Therefore, the center of gravity of the body becomes high, and since the rail member is provided separately, there is a drawback that the number of parts increases. The present invention improves running stability by reducing the number of parts by using a part of the floorboard that forms the body floor, and by lowering the rail part and lowering the position of the center of gravity of the body. be.

Embodiments of the present invention will be described below with reference to the drawings.
2 is a chassis frame, 2 is a garbage storage body mounted on the chassis frame 1 and 1, and 3 is a garbage pushing device that is pivoted 4 at the upper rear end of the body 2 so that it can rotate upward. 3 has a pushing plate (not shown) internally driven as appropriate, and the garbage thrown into the garbage pushing device 3 is accommodated in the body 2 through the opening at the rear end of the body 2 by the pushing plate.

A discharge plate 5 for forcibly discharging the stored garbage is provided in the pod 2 so as to be movable back and forth by a hydraulic cylinder 6.

Next, the garbage storage body 2 will be explained with reference to FIGS. 2 and 3. The body floor surface 7 has a central floor plate 8 that is large enough to span between the left and right chassis frames 1, 1 in the longitudinal direction of the center of the body.
and left and right side floor plates 9, 9 with the central floor plate 8 in between, and the central floor surface 8' is located at a lower position than the side floor surface 9', and the central floor plate 8 is also to form a wastewater groove 10, which extends from the front end to the rear end of the body 2,
The bottom surface of the sewage ditch 10 is gently sloped backward and downward.

The left and right side floor plates 9, 9 are located above the left and right rear wheels and are gently inclined downward toward the central sewage ditch 10, and the inner ends of the side floor plates 9, 9 are shown in FIG. As shown in FIG. The protruding parts 11, 11 overlap the lower surfaces of the parts 11, 11, and the projecting parts 11, 11 serve as rails 13, 13 on which the discharge plate 5 moves back and forth. The discharge plate 5 and the rail 13
, 13 will be explained with reference to FIG. 4.
At the lower part of the side, a shoe case 16 is fixed to which an upper shoe 14 and a lower shoe 15 that slide on the upper and lower surfaces of the overhang 11 are attached. When the upper surface of the upper horizontal surface 14 is pressed, an inner vertical surface 19 connects the upper horizontal surface 18 and the upper and lower horizontal surfaces 18, 17 and stops the upper and lower shoes 14, 15 from moving inward; They each form an outer vertical surface 20 that stops the outward movement of.

The lower shoe 15 is provided with a pressing means 21 that always connects the outer surface of the shoe 15 to the vertical surface 8'' of the central floor plate 8 forming the wastewater groove 9, and the pressing means 21 is attached to the inner surface of the lower shoe 15. Pressing piece 22 and shoe case 1 to be joined
The bolt 23 is screwed into the inner vertical surface 19 of the bolt 6 and has its tip brought into contact with the pressing piece 22.

With the above configuration of the present invention, during garbage collection work, the garbage thrown into the pushing device 3 is accommodated in the body 2 by the operation of the pushing plate provided in the pushing device 3.

Next, the garbage contained in the body 2 will be transported to a disposal site, but during the transport, the sewage in the garbage will drip onto the side floor plates 9, 9 due to the vibrations during driving, and this floor surface 9.
, 9 is guided along the inclined floor surfaces 9, 9 to the central wastewater groove 10, and the wastewater in the wastewater groove 10 is further guided to the garbage pushing device 3 side along the backwardly inclined wastewater groove 10. .

At the disposal site, the garbage pushing device 3 is rotated to the position shown by the two-dot chain line in FIG. 1 to open the rear end of the body 2.
Thereafter, when the hydraulic cylinder 6 is actuated to move the discharge plate 5 backward along the -rails 13, j3, the dust inside the body 2 is forcibly discharged by the discharge plate 5. By the way, by moving the discharge plate back and forth, the lower shoes 15, 1, which are in contact with the vertical surfaces 8'', 8'' of the central floor plate 8, especially
When the outer surfaces of the lower shoes 15, 15 are worn, a gap is created between the side surfaces of the lower shoes 15, 15 and the vertical surfaces 8'', 8'' of the central floor plate 8, which causes the discharge plate 5 to sway horizontally, causing the discharge plate 5 to It is no longer possible to smoothly move back and forth.

Once the above condition is reached, adjust the screwing amount of the tightening bolt 21 and press the lower shoe 15 via the pressing plate 22 toward the vertical surface 8'' side of the central floor plate 8 forming the sewage groove 10. The horizontal vibration of the discharge plate 5 is eliminated, and the forward and backward movement of the discharge plate 5 can be made smooth. A sewage groove is formed by the central floor plate so that the central floor surface is lower than the side floor plate, and a projecting portion extends over the sewage groove at the inner end of the side floor plate. By forming this projecting part as a rail that guides the back and forth movement of the discharge plate, the rail is also formed by a part of the floor plate, which reduces the number of parts and makes it cheaper. Because of this, the center of gravity of the body is lowered,
Driving stability will also improve.

Furthermore, since the wastewater groove is formed in the center of the body, the wastewater can be guided to a predetermined location, making it easy to drain the wastewater.
