Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves shearing and separating the waste at the extrusion port opened in the front of a compact container that is connected to a container to push waste such as garbage into the container, and after the pushing operation is completed. This prevents waste from hanging down or spilling from the extrusion port when the container is separated.
The present invention relates to a waste separation method in a compactor with a simple configuration.

It is already known that the outlet and outlet of a container are connected to the outlet of a compactor, and they are tied together, and the waste such as garbage stored in the compactor is pushed and filled into the container. The compactor has a sufficient clearance between the top surface of its extrusion spout and the pusher ram to prevent waste from becoming trapped between the extrusion spout and the pusher ram during operation.

However, with this configuration, when the container is separated from the compactor after the pushing operation, the waste connected between the compactor and the container hangs down from the extrusion port for a long time or even spills out, which is extremely unsanitary. Not only was there a problem, but there was also a problem that polluted the surrounding area.

Therefore, the present invention separates the waste from the pushing ram by shearing it back and forth and up and down at the extrusion port of the compactor, so that when the container is separated, the waste does not hang down or spill from the extrusion port of the container. In addition to solving the problems of the conventional product, the gap between the extrusion port and the pushing ram is shielded to prevent waste from being seen from the extrusion port of the compact when the container is separated, thereby improving the appearance. The object of the present invention is to provide a method for separating waste in a compactor.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Cp is a compactor fixedly installed on a base, and the compactor main body 1 has an extrusion port 2 on the front side and an input port 3 on the top surface thereof. There is.

A hopper 4 is integrally provided in the input port 3 and extends upward.

A pushing ram 5 is housed in the compact body 1 so as to be slidable back and forth, and the pushing ram 5 has a pushing surface facing the extrusion port 2 on its front surface 6, and its upper surface 7 extends approximately horizontally. , forming a shielding surface capable of shielding the input port 3 of the hopper 4.

・A pushing cylinder 8 is installed between the pushing ram 5 and the compactor body 1.
are connected to each other, and by the expansion and contraction of the pushing cylinder 8, the pushing ram 5 can be slid back and forth, and the pushing surface 6 can push the waste from the hopper 4 to the outside through the extrusion port 2. When the pushing ram 5 is projected, the upper surface 1 of the pushing ram 5 is
3 is closed to prevent waste from falling onto the back surface of the pushing ram 5.

A guide frame 9 extending substantially vertically is provided on both sides of the front part of the compactor main body 1, and an elevating gate 10 having substantially the same width as the pushing ram 5 is engaged with the guide frame 9 so as to be able to rise and fall freely.
The lower ends of lifting cylinders 11 supported by the front wall of the hopper 4 are connected to the upper left and right sides of the lifting gate 10, and the lifting gate g10 can be moved up and down by the expansion and contraction of the lifting cylinders 11.

Then, when the elevator gate 10 ascends, the compact Cp
is stored outside the pushing passage, and when it is lowered, the pushing outlet 2
is protruded into the pushing passage so as to partially block the passage.

The lifting gate 10 has an edge 12 at its lower end,
This edge 12 can cooperate with the front side 6 or top side 7 of the pusher ram 5 to shear the waste, as will be explained in more detail below.

Ct is a container that is integrally connected to the front of Compact Cp via a lashing mechanism (not shown), and when connected,
The entrance/exit 13 opened at one end surface of the container Ct can be aligned with the extrusion opening 2 of the compactor Cp.

Next, the operation of the present invention will be explained mainly with reference to FIG.

First, the case of pushing the waste put into the hopper 4 of the Compact Cp into the container Ct will be described. As shown in FIG. 3A, the 3rd cylinder, which is connected together by the lashing mechanism, is contracted to move the push ram 5 backward, and the waste in the hopper 4 is dropped into the compact body 1. Then, the elevating cylinder 11 is retracted to store the elevating gate 10 above the pushing passage to form a sufficient gap between the upper surface of the extrusion port 2 and the pushing ram 5.

Next, when the pushing cylinder 8 is extended, the pushing ram 5 advances toward the extrusion port 2, as shown in FIG. 3b, and the pushing surface 6 can push the waste into the container Ct.

At this time, since the upper surface 7 of the pushing ram 5 closes the receiving inlet 3 of the hopper 4, there is no fear that the waste will fall onto the back side of the pushing ram 5.

During the pushing operation shown in FIG. 3b, a sufficient gap is formed between the upper surface of the pushing opening 2 and the pushing ram 5.
The operation of the pushing ram 5 will not be hindered by waste material getting caught in the gap.

When the waste is forced into the container Ct by repeating the forward and backward movement of the pushing ram 5, the pushing ram 5 is stopped immediately after the lifting gage g10, as shown in FIG. 3C.

In this case, the gap between the rear side of the lifting gate 10 and the front side 6 of the pusher ram 5 is approximately 10 mm.

Next, when the lifting cylinder 11 is extended and the lifting gate 10 is lowered as shown in FIG. 6, it is possible to shear and separate the waste existing across the extrusion port 2 of the compact container Cp and the entrance/exit port 13 of the container Ct back and forth.

Next, the lifting gate 10 is slightly raised to position its edge 12 directly above the push-in ram 5, as shown in FIG. 3e.

In this case, the gap between the lower surface of the lifting gate 10 and the upper surface 7 of the pusher ram 5 is approximately 10 mm.

Next, when the pushing ram 5 is moved forward as shown in FIG. After vertical shear separation, even if the pushing ram 5 moves forward, the edge 12 of the lifting gate 10 scrapes the separated waste on the pushing ram 5 and stops it in the compactor CP.

Finally, as shown in Fig. 3g, push the push ram 5 into the container C.
The lift gate 10 is stopped at the disengaged position of t, that is, in front of the lift gate 10 where its front surface 6 substantially coincides with the extrusion port 2, and the lift gate 10 is lowered until its edge 12 contacts the upper surface 7 of the pushing ram 5.

As a result, the extrusion port 2 is completely shielded by the pushing ram 5 and the lifting gate 10, so that even if the container Ct is subsequently separated from the compactor Cp, the waste will not hang down or spill from the extrusion port 2, and the compactor The residual waste inside the main body 1 is not visible from the outside.

As described above, according to the present invention, the edge 12 at the lower end of the lifting gate 10 is supported within the compactor body 1 and moves up and down so as to block the upper part of the extrusion port 2, and the edge 12 at the lower end of the lifting gate 10
Immediately after, the waste remaining in the extrusion port 2- is sheared back and forth by the front surface of the pushing ram 5, which is temporarily stopped, and then the elevating gate 10 is temporarily stopped directly above the pushing ram 5, and the Since the waste remaining in the extrusion port 2 is vertically sheared and separated by the edge 12 at the lower end of the lifting gate 10 and the upper surface of the pushing ram 5 that moves forward and backward, the waste remaining in the extrusion port 2 is One common elevator gate 10
Through the cooperation of the lower edge 12 and the pushing ram 5, it is possible to perform shear separation not only in the front-back direction but also in the vertical direction, and by shear separation in these two directions, the residual waste can be reliably removed from the extrusion port 2. Therefore, when the container Ct is separated as in the conventional device, the waste does not hang down or spill for a long time from the extrusion port 2, and an extremely hygienic waste pushing process can be achieved. can.

After the above-mentioned shear separation work, the pushing ram 5 is stopped just before the lifting gate 10, and then the lifting gate 10 is lowered until the lower edge 12 touches the upper surface of the pushing ram 5. Since the extrusion port 2 is shielded by the lift gate 10 and the extrusion gate 10, there is no possibility that the waste inside the compact body 1 can be seen from the outside through the gap between the upper surface of the extrusion port 2 and the pushing ram 5, unlike in the conventional device. Without,
It also has a good appearance.
