Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a compactor for preventing dust and the like from spilling from the upper side end of a pushing ram that is reciprocably housed in the compactor body. This invention relates to a device for preventing spillage of dust, etc. from a compactor, which allows the compactor to operate smoothly.

(Prior art) A pushing ram is fitted into a compactor body that has an input opening on the top and an extrusion opening on the front so that it can reciprocate back and forth, and when the pushing plate operates, the material is thrown into the compactor body from the input opening. In a compactor that extrudes waste such as garbage through an extrusion port and pushes it into a container such as a container, in order to ensure smooth operation of the pushing ram, the upper surface of the pushing ram and the top of the extrusion port of the compactor body are A relatively wide gap of 100 to 200 mm is formed between the wall surfaces, and a slight gap is formed between the side surface of the pushing ram and the inside surface of the compactor body.

(Problem to be Solved by the Invention) For this reason, during the operation of the pushing ram, dirt or the like may get stuck in the gap and cause frictional resistance, or some of the stuck dirt may enter the compactor body from the upper side of the pushing ram. It spills and accumulates, causing the pushing ram to float and promoting the above-mentioned jamming, resulting in wear and deformation of the pushing ram, and furthermore, making it difficult to align the front surface of the pushing ram with the lid of the container that engages and disengages. There were flaws.

To explain these drawbacks in more detail with reference to the drawings, A is a compactor, the box-shaped compactor main body 1 has an extrusion port 2 in its front face and an input port 3 in the front part of its upper wall. A hopper 4 is formed integrally with the compactor body 1 on the compactor body 1 . A pushing ram 5 is housed in the compactor body 1 so as to be able to reciprocate back and forth, and this pushing ram 5 has a pushing surface 6 facing the extrusion port 2 formed on its front surface, and an upper surface thereof. An opening/closing surface 7 is formed on the opening/closing surface 7 for opening/closing the input port 3. A telescopic cylinder 8 extending in the longitudinal direction of the compactor body 1 is connected between the back surface of the pushing ram 5 and the rear wall of the compactor body 1 .

Further, a plurality of skill rollers 10 supported by legs 9 are installed inside the pushing ram 5.
Pushing ram 5 by the telescopic operation of the telescopic cylinder 8
The front and rear sliding movement is made stable.

Reference numeral B designates a container into which waste such as garbage extruded by the compactor main body 1 is packed, and an inlet 11 larger than the extrusion port 2 of the compactor A is opened in one end wall of the container.

The compactor body 1 and the container B are connected together by a securing mechanism (not shown).

Incidentally, the dust spilling from the side end of the pushing ram through the gap C between the opening/closing surface of the pushing ram 5 and the inner surface of the upper wall of the compactor body has been conventionally prevented by a spillage prevention device shown in FIG. That is, hoppa 4
At the lower end of the support bracket 12 fixed to the inner wall,
A stopper 13 is provided to extend along the inner wall 1a of the compactor main body 1 at the front and rear thereof, and a pusher ram 5 is provided.
A plate member 7a forming the opening/closing surface 7 is fixed by welding to the upper surface thereof, and the upper surface of the plate member 7a is positioned so as to be substantially in contact with the lower surface of the stopper 13.

However, fine particles such as glass fragments and dust move on the upper surface of the plate material 7a and fall down from the side edges of the plate material 7a, and especially when the side edges of the material 7a are worn down due to biting of dust, the spillage is prevented. This became noticeable, and the above-mentioned drawbacks could not be overcome.

(Means for Solving the Problems) In order to solve the above-mentioned drawbacks, the present invention provides a compactor body having an input port connected to the hopper at the front of the upper surface and an extrusion port facing the extrusion port at the front surface. A pushing ram having a pushing surface and an opening/closing surface capable of opening and closing the input port is housed so as to be able to reciprocate back and forth,
In a compactor in which waste such as garbage thrown into the compactor body from the input port can be pushed out from the extrusion port by forced reciprocating operation of the push plate, a stopper is provided at the upper part of the inner surface of the compactor main body. At the same time, a guide rail is removably extended to the upper surface side end of the plate material forming the opening/closing surface, and the lower surface of the stopper and the upper surface of the guide rail are arranged so as to be substantially in contact with each other. Furthermore, spillage is reduced as much as possible to enable smooth and light operation of the compactor with a small amount of power, and there is no hindrance to automatic engagement and disengagement with the container side lid.

(Embodiment) Next, an embodiment of the present invention will be described with reference to drawings (the general structure of the compactor and container is the same as that of the conventional Fig. 1, so the explanation will be omitted). Fig. 3 is the conventional Fig. 2. This is a spill prevention device compatible with
A slight gap is formed between the upper surface of the a-side end and the lower surface of the stopper 13, and a guide rail 15 is installed at the end of the plate 7a using the bolt 14 so as to close the gap with the stopper 13. This will be extended. Therefore, since the fine dust on the plate material 7a is once prevented from further lateral movement by the guide rail 15, the dust that falls beyond the guide rail 15 into the compactor body 1 from the side edge is significantly reduced. Decrease. Incidentally, if the guide rail 15 becomes worn due to some of the above-mentioned dust, it is sufficient to loosen the bolt 14, remove it, and replace it.

Further, even if the plate material 7a becomes worn or deformed due to long-term use, it can be replaced, and in particular, it can be used more effectively if the upper and lower surfaces are reversed.

(Effects of the Invention) As described above, according to the present invention, the guide rail is removably extended to the upper side end of the plate material that forms the opening/closing surface of the pushing ram, and the upper surface is attached to the upper part of the inner surface of the compactor main body. By arranging the stopper so as to be substantially in contact with the lower surface of the extended stopper, it is possible to reduce the amount of dust spilling from the side edge of the plate as much as possible and maintain smooth operation of the pushing ram.
