First, after the Kakiage Itakame 4 has descended, the link Dentomi is descended.
Next, move the raking board Gunkame upward to scrape up the garbage, and then move the push board electric 5 backwards and move the link wealth 6 upward, and then move forward with the push board fugitive. One pushing operation is completed by pushing the garbage into the main body 4. When the above-mentioned scraping plate Tomi-kame is rotated upward, the chain 28 comes into contact with the inner surface of the rear door body. It deforms and rises according to the shape of the garbage (therefore, scattering of the garbage, etc. is prevented).The above operation is controlled by a control circuit including a timer relay, a limit switch, etc.

In addition, it is also possible to apply a chain link.Example 2 As shown in Figure 2, this example differs from Example 1 only in the garbage pushing device; Since it is the same aircraft as No. 1, the same reference numerals will be used for the same components and detailed explanations will be omitted.

24G is a rear door body, and a guide groove 25 inclined downward toward the rear of the rear door body 241 is provided.
A sliding plate 26 extending to the full width is housed in the information plate 4, and sliding members 27 are fixed to both side edges of the information plate 26 so as to be slidably connected to the guide groove 25.

Between the driving member 27 and the lower part of the rear corpse 24, a first telescopic cylinder 2 provided on the outside of the rear door body 24 is connected along the diagonal direction of the guide groove 25 to the first telescopic cylinder 28. The sliding plate 26 moves up and down along the guide groove 25 by the expansion and contraction of the sliding plate 26.Furthermore, at the lower end of the sliding plate 26,
A pushing plate tortoise 5 that extends completely in the lateral direction of the rear corpse 24 is pivoted on a support shaft 29 so as to be able to swing back and forth, and a space between a protruding piece 38 protruding from the back surface of the pushing plate 15 and the upper part of the sliding plate 26 is provided. A third second telescopic cylinder 31 is connected to the second telescopic cylinder 31, and the pushing plate 15 is swung back and forth around the support shaft 29 by the telescopic operation of the second telescopic cylinder 31.

A chain member similar to that in the first embodiment is suspended from the green portion at the lower end of the pushing plate turtle 5. Next, to explain the operation of the above device, FIG. 2 shows the end of the garbage pushing stroke, in which the first telescopic cylinder 28 is extended and the sliding plate 26 is raised together with the pushing plate turtle 5. The second telescopic cylinder 31 is in an extended state.

First, when the sliding plate 26 reaches the upper end, the second telescoping cylinder 31 is shortened and the pushing plate 15 is rotated backwards (during this time, the garbage is thrown into the storage tank 12 from the loading mechanism).
When the pushing plate i5 rotates backward and reaches the limit position,
The first telescopic cylinder 28 is shortened to move the sliding plate 26 downward, and the thrown garbage is crushed by the pushing plate tendon 5. When the sliding plate 26 descends and reaches the limit position,
The second telescopic cylinder 31 is extended and the pushing plate 15 is rolled forward to secondarily compress the crushed garbage. Furthermore, when the push plate 15 rotates forward and reaches the limit position,
The first telescopic cylinder 28 is extended to move the sliding plate 2 upward, and the compressed garbage is pushed into the main body 4 as the pushing plate 18 rises. When the pushing plate 15 is rotated and raised, the chain 23 is always in contact with the inside of the rear door body 24, so that scattering of dust, sewage, etc. is prevented. When the pushing plate 15 rises, it returns to its original state and completes the cycle of loading, crushing, and compressing garbage.

Embodiment 3 This example is applied to a rotary type garbage pushing device in which the scraping plate rotates as shown in FIG.

The garbage pushing device includes a scraping plate 14 that rotates clockwise by rotating means (not shown) and a pushing plate 15 that can push the garbage scraped up by the scraping plate 1.4 into the main body 4. (the rotating means is not shown), and a chain 23 similar to that in the first embodiment is suspended from the green end portion of the pushing plate 15.

In this example, the chain is provided at the tip end twill portion of the pushing plate 15, but it is of course possible to provide it at the tip edge portion of the scraping plate 14. Next, to explain the operation of the above device, the pushing plate 15 starts to operate from the forward position and the scraping plate i4 from the raised position to push the garbage in the storage tank 2 into the main body 4.

First, the raking plate 14 is lowered in a clockwise direction, and then the raking plate 14 is rotated upward to scrape up the dirt, and the pushing plate 15 is rotated backward.The raking plate 14 reaches a predetermined position. Then, the pushing plate 15 is rotated forward to push the garbage into the main body 4, and one pushing operation is completed.
When rotating forward, the chain 23 moves forward while contacting the surface of the raking plate 14 and preventing dust etc. from scattering.
The above operation is controlled by a control circuit consisting of a timer relay, limit switch, etc.
According to the present invention, since a deformable chain member such as a chain is provided in the pushing means, it is possible to prevent sewage and damaged objects from scattering to workers during garbage loading.

Further, if the chain member is made of a metal chain, the durability is significantly improved compared to the conventional chain member made of synthetic rubber or the like.
