[0002]

2. Description of the Related Art In the above-mentioned waste disposal apparatus, the waste put into a hopper is moved between a plurality of rotary blades provided at the bottom of the hopper by its own weight or by the weight of other waste put later. It is pushed in and crushed and shredded. However, relatively light wastes such as paper cups and PET bottles are not smoothly pushed between the rotary blades even when thrown into the hopper, and the treatment efficiency is reduced. Therefore, in such a case, as a device for efficiently pushing the waste material between the rotary blades, for example, JP-A-8-117628 and JP-A-6-70839 provide a pushing member on the side or above the hopper, There is disclosed an invention and a device for intermittently taking in and out of the hopper toward the bottom of the hopper by a cylinder device, thereby forcibly pushing the waste in the hopper to the bottom and improving the processing efficiency.

[0003]

However, in the above-mentioned inventions and inventions, it is necessary to separately install a cylinder device for operating the pushing member, which leads to an increase in size of the entire device and an increase in cost. In addition, when the hopper is provided on the side of the hopper, the capacity of the hopper is limited. Further, in a configuration in which the pushing member enters and exits from above the hopper, the hopper cannot be covered during the operation of the pushing member, so that there is a possibility that waste may jump out of the hopper when the pushing member rises.

Accordingly, the first aspect of the present invention has a simple structure that does not require the use of an additional structure such as a cylinder device for its operation, even if a pushing member is provided.
It is another object of the present invention to provide an easy-to-use waste disposal apparatus which does not hinder the opening and closing of the hopper lid even during the operation of the pushing member.

[0005]

Means for Solving the Problems In order to achieve the above object, the invention according to claim 1 moves in the hopper at least in the vertical direction in conjunction with the rotation of the rotary blade,
A push member capable of guiding the waste to the rotary blade side is provided. Further, in addition to the object of the first aspect, in order to easily realize the interlocking with the rotation of the rotary blade in the pushing member, the invention according to the second aspect further includes a rotary shaft of the rotary blade in a radial direction thereof. A first link member to be fixed and a second link member connecting the free end of the link member and the pushing member movably supported in the vertical direction.
The third aspect of the present invention provides, in addition to the object of the second aspect,
In order to prevent damage to the push-in member and the like when foreign matter is mixed in the hopper and resistance to the downward movement of the push-in member is established, the connection between the push-in member and the second link member is
The elastic piece provided on the pushing member and the elastic piece are locked by the locked portion provided on the second link member, and the resistance applied when the pushing member moves downward is large. Then, the elastic piece is separated from the locked portion.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall view of a waste treatment apparatus.
The waste treatment apparatus 1 has a hopper 2 provided with an inlet 3 for introducing waste such as empty cans and PET bottles above, and a rotatably supported base 4 at the bottom of the hopper 2. A pair of rotary blades 5, 5; a driving motor 6 for rotating the rotary blades 5, 5;
A lower frame 7 containing a collection box for collecting the shredded waste is provided. Reference numeral 8 denotes a gear box interposed between the driving motor 6 and the rotary blades 5 and 5, and reference numeral 9 denotes a lid that is hinged to the hopper 2 and that can open and close the input port 3.

As shown in FIGS. 2 and 3, in the base 4, one of the rotary shafts 10 of the rotary blades 5 and 5 protrudes forward (left side in FIG. 3) from the base 4 and rotates. One end of a rotating plate 11 as a first link member is radially fixed to the shaft 10, and the other end is rotatably connected to a lower end of a connecting rod 12 as a second link member by a shaft 13. ing. The connecting rod 12 extends upward through the connecting rod guides 14, 14 laid horizontally in front of the base 4.
It is a thing to pass through. Inside the presser bar carriage 15, carriage rollers 16, 16 are disposed on the lower front side and the upper rear side of the connecting rod 12, respectively, and roll the front and rear surfaces of the connecting rod 12. At the same time, a limit spring 17 which is a leaf spring is provided on the upper front side of the presser bar carriage 15, and a locking piece 17 a at the tip thereof is locked in a locking groove 12 a formed in the front surface of the connecting rod 12. In a normal state, the presser bar carriage 15 is hung on the connecting rod 12 at a position where the locking piece 17a engages with the locking groove 12a. On the other hand, on the lower rear side of the presser bar carriage 15, a presser bar 18 as a pressing member is horizontally protruded rearward, and is provided with a pair of presser bar guides 19, 19 which are suspended from the front center of the hopper 2. Through the gap and the slit 20 formed vertically in the center of the front surface of the hopper 2,
It protrudes into the hopper 2. A guide roller 21 having a flange 22 provided in front thereof is loosely fitted to the presser bar 18 and is disposed between the presser bar guides 19, 19, and the presser bar 18 accompanying the vertical movement of the presser bar carriage 15. Guides the operation of.

In the waste disposal apparatus 1 configured as described above, waste such as empty cans and plastic bottles is put into the hopper 2, the lid 9 is closed, and the driving motor 6 is operated.
When the rotary blades 5, 5 are rotated via the gear box 8,
The rotation of the rotating shaft 10 causes the rotating plate 11 to rotate, causing the lower end of the connecting rod 12 axially attached to the tip of the rotating plate 11 to make a circular motion. Above the connecting rod 12, only the vertical movement of the suspended presser bar carriage 15 is allowed by the presser bar guides 19, 19, so that the presser bar carriage 15 corresponds only to the vertical movement amount of the connecting rod 12. Moves up and down, and at the same time, the presser bar 18 moves up and down in the hopper 2.
As the presser bar 18 moves up and down, the waste in the hopper 2 is agitated, and when the presser bar 18 descends, the waste below the presser bar 18 is pressed and pushed between the rotary blades 5 and 5 (FIG. 4). ). As described above, since the agitating action and the pushing action are performed in the hopper 2 by the vertical movement of the presser bar 18, even the light weight waste does not stagnate in the hopper 2, and the rotating blades 5, 5 can be surely reached. Guided, crushing and other processes are performed efficiently in a short time.

According to the above embodiment, the holding rod 18
The processing efficiency is improved by agitation and pushing in the hopper 2 by the above. In particular, the structure in which the presser bar 18 is automatically moved up and down by the rotation of the rotary blades 5 and 5 enables simple and rational addition to the rotary shaft 10 and the like without using a separate pushing device using a cylinder device or the like. The above-described effects can be obtained with a simple configuration, and miniaturization of the entire apparatus and suppression of cost increase can be expected. Further, since there is no need to provide a large pushing device on the side of the hopper 2, there is no limitation on the volume of the hopper 2. Further, since the presser bar 18 always moves up and down in the hopper 2, the hopper 2 can be used with the lid 9, and the problem that the wastes pop out cannot occur. On the other hand, the presser bar 18 is forcibly moved up and down by the rotation of the rotating shaft 10, but may come into contact with a foreign substance or the like in the hopper 2, causing a large resistance to lower the presser bar 18. So this resistance is the limit spring 17
When the locking force between the locking piece 17a of the connecting rod 12 and the locking groove 12a of the connecting rod 12 is exceeded, the limit spring 17 separates from the locking groove 12a due to its elasticity, and the pressing rod carriage 1
Since only the connecting rod 12 is left as it is while leaving 5, the problem that the presser bar carriage 15 is damaged or the presser bar 18 is bent is prevented beforehand. A positioning bolt 23 is screwed onto the back surface of the connecting rod 12 at a position where the presser bar carriage 15 abuts on the lower end of the presser bar carriage 15 in a normal state suspended via the limit spring 17 as shown in FIG. Thus, the lower limit position of the presser bar carriage 15 with respect to the connecting rod 12 is regulated, so that re-locking after the lock of the limit spring 17 is released is also ensured.

In the above embodiment, a crank mechanism for converting the rotation of the rotary blades 5 and 5 into a vertical movement of the presser bar 18 via the connecting rod 12 and the presser bar carriage 15 is employed. 18 is not limited to only vertical movement, for example, FIG.
, The upper end of the connecting rod 12 is axially attached to the eccentric position of the disk 24 rotatably supported in the hopper 2,
8 is provided at the eccentric position of the disk 24 as well.
By rotating the disk 24, the presser bar 18 can be caused to make a circular motion. The stirring and pushing action described above can also be obtained with the presser bar 18 that moves in a circular motion. In addition, a link mechanism or the like is used for the presser bar 18 to impart an oblong or elliptical motion, or a gear is provided on the rotating shaft 10 to apply the above-described motion to the presser bar 18 in combination with a desired reduction mechanism. Is also good. In the above-described embodiment, the connecting rod 12 is connected to one of the pair of rotary blades 5 and 5, and one presser bar 18 is moved. However, the same link mechanism is adopted for each of the plurality of rotary blades. A structure in which two or more presser bars are moved may be used. Further, in the above embodiment, the waste treatment apparatus for crushing and shredding hollow containers such as empty cans and PET bottles has been described. However, the present invention can be applied to other waste treatment apparatuses. is there.
