Description

[Detailed description of the invention] This invention is based on the idea that when garbage is loaded into a garbage collection vehicle, easily breakable garbage such as glass products gets caught between the side plate and push plate of the garbage dumping box, causing damage and the pieces scattering backwards. The present invention relates to a device that prevents this from occurring.

B. Prior art In general, garbage loading work on garbage collection vehicles is the first step.
This is done as shown in the figure. That is, the garbage thrown in from the input port 2 provided at the rear of the garbage input box 1 is
A scraping plate 3 rotatably installed in the garbage input box 1 scrapes up the garbage, and the garbage is stacked in the garbage storage box 5 by a pushing plate 4 swingably installed above the scraping plate 3. let them get involved.

By the way, when the garbage storage box 5 becomes full by repeating the loading operation using the scraping plate 3 and the pushing plate 4, a reaction force is generated that presses the pushing plate 4 against the garbage, and the pushing plate 4 is pushed. When the board 4 swings from the back to the front to load the garbage on the scraping board 3 into the garbage storage box 5, if the trash on the scraping board 3 contains easily broken glass products, etc. In some cases, debris such as glass products was not loaded smoothly and got caught in the gap 6 between the pushing plate 4 and the scraping plate 3. If the pushing plate 4 continues to swing forward in this state, the debris such as glass products that have been caught will break, and the pieces will scatter backwards, causing the operator working behind the garbage input box 1 to Accidents that resulted in injuries occurred and became a serious problem. Therefore, in the past, as shown in FIGS. 1 and 2, a hard shielding plate 8 made of steel plate or the like is attached to the lower part of the rear surface 7 of the pushing plate 4 by means of a pivot 9 so that it can swing freely over the entire width of the pushing plate 4. It is supported by hanging. The length of the shielding plate 8 is set so that the lower end of the shielding plate 8 comes into contact with the upper surface of the scraping plate 3. Therefore, when loading garbage, when the pushing plate 4 swings forward, the shielding plate 8 moves following the pushing plate 4 with its lower end in contact with the upper surface of the scraping plate 3. Even if dust such as glass products gets caught in the gap 6 between the pushing plate 4 and the scraping plate 3 and is damaged, the pieces are blocked by the shielding plate 8 without scattering backwards. Note that since this shielding plate 8 is made of a steel plate or the like having a considerable weight, the shielding plate 8 will not open due to collision with fragments of the glass products or the like.

However, when the pushing force of the pushing plate 4 is increased, for example, when the garbage in the garbage storage box 5 becomes full, glass products, etc. are also deposited in the gap 11 between the side plate 10 of the garbage input box 1 and the pushing plate 4. Debris that is easily damaged gets caught. If the pushing plate 4 continues to swing forward in this state, the debris caught in the gap 11 will be damaged, and the debris will scatter backward. Therefore, in recent years, as shown in FIG. 3, a shielding plate 14 consisting of a rectangular rubber plate 12 having a predetermined thickness and a mounting member 13 fixed to the long side of the rubber plate 12 is inserted on both sides of the rear surface 7 of the plate 4. It is removably attached along the edges 15, 15.
Therefore, when the pushing plate 4 swings forward to load the garbage on the scraping plate 3, the garbage such as glass products is pushed into the gap 1 between the side plate 10 of the garbage input box 1 and the pushing plate 4.
Even if the fragments are bitten and damaged and try to scatter backwards, they are blocked by the shielding plate 14.

However, when the garbage in the garbage storage box 5 becomes full, when the pushing plate 4 swings forward, the garbage such as the bars 16 is forcibly removed by the garbage already loaded in the garbage storage box 5. It may be pushed out from the shielding plate 14. At this time, the rubber plate 12 of the shielding plate 14 is deformed in a curved manner near the bar 16, creating a gap 17, and other debris may scatter backwards from this gap 17, which is extremely dangerous. Ta. In addition, the above-mentioned bar 16 caught in the rubber plate 12 of the shielding plate 14
However, there was a risk that the rubber plate 12 would scatter backward after separating from the shielding plate 14 due to the elastic restoring force of the rubber plate 12.
Therefore, in order to prevent the shielding plate 14 from deforming in a curved manner, the thickness of the shielding plate 14 may be increased, but if the thickness is increased, the flexibility will be inferior to that of a thinner plate, resulting in increased wear. There was a problem that the durability decreased.

B. Purpose of the invention The purpose of the invention is to prevent debris such as glass products from breaking and scattering backwards when they are loaded into the gap between the side plate of the garbage disposal box and both edges of the push plate. The objective is to provide a device that completely prevents this.

C. Structure of the invention The present invention is a garbage scattering prevention device for a garbage collection vehicle in which a shielding member is provided along both edges of the rear rear surface of a push plate that is swingably installed in a garbage input box. The shielding member is constructed by planting a large number of bundled hard hairs in a zigzag pattern at a regular pitch on one end surface of the mounting plate.

D. Example An example of the present invention will be described based on FIGS. 4 to 6. In addition, in Figures 4 to 6,
Components that are the same as those in FIGS. 3 to 3 are designated by the same reference numerals and their explanations will be omitted.

The dust scattering prevention device for a garbage collection vehicle according to the present invention is characterized in that a shielding member 18 is provided along both side edges 15, 15 of the rear surface 7 of the push plate 4, as shown in the figure.

As shown in FIG. 4, the shielding member 18 is made by bundling a large number of hard bristles 21 made of nylon or the like on one end surface 20 of a mounting plate 19 made of plastic having a predetermined thickness, for example. A plurality of mounting holes 22 are bored at a fixed pitch along one side edge of the mounting plate 19. This shielding member 18 is shown in FIGS.
As shown in the figure, the bristles 21 are removably attached and fixed by bolts or the like along both side edges 15, 15 of the rear surface 7 of the pushing plate 4 with the bristles 21 facing outward. At this time, the shielding member 18 is positioned such that the tips of the bristles 21 come into contact with the side plate 10 of the garbage input box 1.

The present invention has the above configuration, and when the garbage storage box becomes full of garbage during garbage loading, the push plate 4
When the bin swings forward, breakable debris such as glass products gets caught in the gap 11 between the side plate 10 of the garbage disposal box 1 and the push-in plate 4, causing damage, and even if the pieces try to scatter backwards, the above-mentioned It is blocked by the shielding member 18. Moreover, as shown in FIG. 6, even if the debris such as the bar 16 is forcibly pushed out from the shielding member 18 by the debris already loaded in the garbage storage box, the shielding member 18 is brush-shaped. Because there is
No gaps are formed near the bar 16, preventing other debris from scattering backwards, and the bar 16
The energy that tends to scatter backward is also absorbed, and after separating from the shielding member 18, the shield member 18 does not scatter backward and immediately falls. Furthermore, since the shielding member 18 is made of hard bristles 21, even if pieces of dust collide with the shielding member 18, they will not penetrate through the shielding member 18 due to the collision force. Further, since the shielding member 18 is brush-shaped, there is no problem even if the pushing plate 4 is reversed from the front to the rear, and it can be replaced if it wears out.

In the above embodiment, the shielding member 18 has approximately the same length as both side edges 15, 15 of the pushing plate 4,
The present invention is not limited to this, but for example, as shown in FIG.
8' may be arranged in a row along both side edges 15, 15 of the pushing plate 4 and fixedly attached.

E. Effects of the invention According to the invention, when garbage is loaded, easily breakable garbage such as glass products gets caught in the gap between the side plate of the garbage input box and both edges of the push plate, and the pieces of debris are thrown backwards. Even if it tries to scatter, it will be blocked by the shielding member. Moreover, even if the garbage such as bars is forcibly pushed out from the shielding member by the garbage already loaded in the garbage storage box, unlike conventional shielding plates made of rubber plates, it will not be able to reach the vicinity of the bars. Since no gap is formed, other pieces of dust will not be scattered backward through the gap. Moreover, since this shielding member is brush-shaped, the bar itself falls immediately after being separated from the shielding member without scattering backward. Therefore, it is possible to completely prevent debris fragments such as glass products and bars from scattering backwards, and the safety of workers working behind the garbage input box is also ensured. Furthermore, since the shielding member according to the present invention is brush-shaped and has flexibility, its durability is greatly improved.
