Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a dust scattering prevention device for a garbage collection vehicle, and is particularly concerned with the prevention of collisions between the mounting bracket of the closing plate provided at the lower end of the pushing plate and the rotating plate. This invention relates to a dust scattering prevention device for a garbage collection vehicle that is prevented from being damaged by.

[Conventional technology]

Conventional garbage collection devices for garbage collection vehicles include a rotary plate for scraping in garbage that is provided at the bottom of the tailgate so as to be rotatable around a horizontal axis, and furthermore, a rotary plate for scraping in garbage is provided at the bottom of the tailgate to push the garbage scraped in by the rotary plate into the garbage collection section. , a type in which a push plate is provided that can be freely swung back and forth is known.

This type of garbage collection vehicle will be explained with reference to FIGS. 4 and 5. In FIG. 4, reference numeral 1 denotes a garbage collection box, behind which a tailgate 2 is provided in a well-known manner, and garbage is fed into the garbage collection storage box 1 through this tailgate.

As shown in FIG. 5, the tailgate 2 has side plates 2a on both sides and a hopper 2b at the bottom, and is further provided with a hopper door 3. A base end of a known rotary plate 5 for picking up dust is supported on a shaft 4 supported by both side plates 2a. The rotating plate 5 is
The leading edge 5a rotates so as to take a trajectory shown by a chain arrow 6, and scoops up the garbage dumped onto the hopper 2b.

The upper end of a garbage pushing plate 8 is supported on a pivot shaft 7 supported by the tailgate side plate 2a at an upper position inside the tailgate 2, and the pushing plate 8 is movable around the pivot shaft 7. It's getting old. When the rotary plate 5 rotates up to the position shown in Figure 5 and scrapes up the garbage, the garbage pushing plate 8 moves from the rear (right side in Figure 5) to the front (left side in Figure 5) as is known. The garbage collection box 1 swings clockwise to push the garbage on the rotary plate 5 into the garbage collection box 1.

When the push plate 8 swings back and forth as described above, the sewage contained in the garbage and the sewage pushed out from the garbage enter the gaps between the left and right edges of the push plate 8 and the tailgate side plate 2a, and It often scatters backwards through the gap between the plate 8 and the rotary plate 5, hitting workers. This is extremely unsanitary.

In order to eliminate this problem, conventionally, a shield plate 10 made of a flexible material is attached to the mounting bracket 1 along the entire lower edge of the push plate 8, which has a substantially rectangular front surface.
1, and furthermore, side bars and closing plates 12 made of the same material as the chopsticks and closing plates 10 are attached to both side edges of the push-in plate 8, and the gaps are closed and sewage etc. is scattered backwards. I was trying not to.

By the way, the driving of the rotary plate 5 and the pushing plate 8 is normally automatically controlled, and after the pushing plate 8 stops at the position shown by the chain line in FIG. 5, the rotating plate 5 moves to the position shown by the solid line. It is designed to rotate clockwise from Therefore, during normal operation,
The tip edge 5a of the rotary plate 5 and the mounting bracket 11 do not collide.

However, during the garbage collection work, the worker may press a manual operation push button (not shown) to drive the rotary plate 5 and the pushing plate 8, and the pushing plate 8 may be inadvertently moved as shown by the chain line in FIG. Before swinging to the indicated position, the rotary plate 5 may be rotated clockwise to cause the tip edge 5a of the rotary plate 5 and the mounting bracket 11 to collide. If the mounting bracket 11 is damaged due to this collision, the function of the shield plate 10 will be lost, and in some cases, the mounting bolts will be damaged, making it impossible to remove the shield plate 10.
It has become a big problem.

[Problem that the invention attempts to solve]

Therefore, the purpose of this invention is to provide a dust scattering prevention device that prevents damage to the mounting bracket of the closing plate even if the leading edge of the rotary plate comes into interference contact with the lower end of the back of the push plate due to incorrect operation. It is about providing.

[Means for solving problems]

In order to achieve the above object, the present invention includes a rotary plate that is rotatable about a horizontal axis above the bottom of the tailgate, and a horizontal axis of the rotary plate. In a garbage collection vehicle equipped with a pushing plate that is supported in a downwardly hanging manner by a horizontal shaft located above and is oscillated back and forth so as to push the garbage scraped in by a rotating plate into a garbage collection section. , a closing plate made of a flexible material is removably attached to the back of the pushing plate using a mounting bracket so as to protrude from the lower edge of the pushing plate;
At least one stopper is integrally formed on the back surface of the push plate, and the back surface of the stopper projects rearward from the rear surface of the mounting bracket,
The present invention is characterized in that the lower end edge of the stopper, which protrudes downward from the lower end edge of the mounting bracket, restricts the leading edge of the rotary plate rotating in the scraping direction.

〔Example〕

An embodiment of the dust scattering prevention device for a garbage collection vehicle according to the present invention will be described below with reference to FIGS. 1 and 2. Note that in FIGS. 1 and 2, the same parts as in FIG. 5 are designated by the same reference numerals. In addition, a loading device built into the tailgate 2, that is, a rotating plate 5
The mounting position and operation of the push-in plate 8 are the same as the conventional one shown in FIG. 5, and therefore their explanation will be omitted.

FIG. 1 is an enlarged perspective view of a part of the lower end of the pusher plate 8, and a comb plate 10 is attached to the lower end of the rear surface of the pusher plate 8. As shown in FIG. The sheath closing plate 10 is made of a flexible material plate such as rubber, plastic, cloth, etc., and is attached so as to protrude downward from the lower end edge 8a of the push plate 8. To install this shutter closing plate 10, use the mounting bracket 11.
It is done through. That is, as is clear from FIG. 1, the sheath closing plate 10 is brought into contact with a predetermined position on the back surface of the pushing plate 8, and the presser plate 12 is applied from above, and the sheath closing plate 10 and the presser plate 12 are each pressed. After aligning the appropriate mounting holes provided in the parts, the parts are screwed and fixed with bolts 14.

According to the present invention, a hard stopper 15 made of metal, for example, is fixed by welding directly to the push plate 8 at a suitable location on the lower end of the back surface of the push plate 8 without using fastening elements such as bolts or nuts. It is formed by This stopper 15 has a lower edge 15a.
protrudes downward from the lower edge of the holding plate 12, and its back surface 15b is connected to the bolt 14.
It is fixed so that it protrudes backward from the end face of the head by a height H.

Next, the action of the above-mentioned stopper 15 will be explained with reference to FIG. 2, which shows the positional relationship between the rotating plate 5 and the pushing plate 8. During normal operation, the rotary plate 5 is
As shown by the solid line in the figure, the pushing plate 8 is stopped at a position where it has fully advanced forward, and the tip edge 5a of the rotary plate 5 is at the height H of the back surface 15b of the stopper 15.
Since it rotates along the outer side, the tip edge 5a and the mounting bracket 11 do not collide. However, when the pushing plate 8 does not reach the most advanced position and rotates to shovel the dust in a positional relationship where the leading edge 5a of the rotary plate 5 and the stopper 15 interfere with each other, the leading edge 5a is As shown by the chain line, the position where it collides with the mounting bracket 11 is rotated. When the leading edge 5a of the rotary plate 5 collides with the lower edge 15a of the stopper 15 in this way, the rotary plate 5 stops at the collision position and is hydraulically driven to prevent further clockwise rotation. The circuit has been devised.

This prevents damage to the presser plate 12 and the bolts 14 that fix it. Also, stopper 1
5 is formed integrally with the pusher plate 8 by welding, so that the rotary plate 5 is attached to this stopper 15.
Even if the impact load at the time of a collision becomes quite large, the stopper 15 is firmly installed and will not fall off. Therefore, this stopper 15 prevents rotation of the rotary plate 5 and reliably protects the holding plate 12 and bolts 14.

Further, FIG. 3 is a perspective view showing the lower end portion of the pushing plate 8 of the dust scattering prevention device according to another embodiment.
On both sides of the lower end of the rear surface of the pushing plate 8, wall portions 16 having an appropriate width are left to function as stoppers 15, and a recess 17 is formed in the center of the lower end. The depth H of this recess 17 is set to a dimension corresponding to the height H of the stopper 15 shown in FIG. A bottom wall 18 corresponding to the bottom of the recess 17 has a shield plate 1 made of flexible plate material.
0 is attached via a mounting bracket 11 similar to that illustrated in FIG. Further, the lower end edge of the presser plate 12 is connected to a wall portion 16 that functions as the stopper 15.
It is mounted so as to be located above the lower edge 16a of the.

Therefore, even if the rotary plate 5 rotates through the position indicated by the chain line in FIG.
6, but does not collide with the presser plate 12 and bolts 14.

Further, since the push plate 8 and the stopper are completely integrated, the solid stopper 15 reliably stops the rotating shaft 5 even if the impact load when the rotating plate 5 collides is large. Moreover, according to this embodiment, since the mounting bracket 11 can be mounted as a single plate in the recess 17, there is an advantage that the replacement work of the shutter closing plate 10 is facilitated.

[Effect of idea]

As is clear from the above description, according to the present invention, at least one stopper is integrally formed on the back surface of the push-in plate, and the back surface of the stopper protrudes rearward from the rear surface of the mounting bracket. At the same time, since the lower edge of the stopper protruding downward from the lower edge of the mounting bracket restricts the leading edge of the rotary plate rotating in the scraping direction, the leading edge of the rotating plate rotates in the scraping direction due to operator error. Even if a large impact load is applied in the event of a collision, the rotating plate will be reliably stopped by the solid stopper, so the mounting bracket will not be damaged and the shutter closing plate can be easily replaced. .
