(Embodiment 1) FIG. 1 is a cutaway perspective view showing the internal structure of a crusher according to Embodiment 1 of the present invention.

The crushing device shown is a crushing device for treating kitchen waste as a processed material, for example, a sink 1 provided with a faucet 13.
2 and a cylindrical hopper (hollow structure) 4
At the upper end of the container, there is an inlet 10 into which kitchen garbage to be treated is introduced.
Are formed to open in the sink 12. Note that the hopper 4 only needs to be cylindrical, and does not necessarily need to be cylindrical.

In the upper part of the hopper 4, a crushing chamber 6 for crushing the garbage is formed, and on the lower side, a crushed material inflow chamber 8 into which the crushed garbage flows is formed on the bottom surface 14 so as to be formed. I have. A gap 19 is formed between the bottom surface 14 and the inner wall of the hopper 4, and the crushed material crushed in the crushing chamber 6 flows into the crushed material inflow chamber 8 through the gap 19. Further, a discharge pipe 9 for discharging the pulverized material to the outside of the apparatus is connected to the pulverized material inflow chamber 8.

On the upper surface of the bottom surface 14, a number of convex portions 15 and concave portions 16 are provided. In addition, cutouts 17 are formed at predetermined intervals on the periphery of the bottom surface 14.
Further, the bottom surface 14 is formed with a drain hole 18 which is a through-hole for allowing the crushed material and water of the garbage in the crushing chamber 6 to fall into the crushed material inflow chamber 8.

Below the pulverized material inflow chamber 8, ie, the hopper 4
A motor 1 as a power source is installed at the bottom of the motor.
The motor 1 is provided with a crushed material
Is mounted along the center axis of the hopper 4.

Two rotary blades 3 extending vertically to the vicinity of the inner wall of the hopper 4 are attached to the position of the rotary shaft 2 facing the pulverizing chamber 6, and are rotated by the rotation of the rotary shaft 2. The number of rotary blades 3 is not limited to two shown in the present embodiment.

A first fixed blade 7 is provided on the inner wall of the hopper 4.
Are projected and fixed, and cooperate with the rotary blade 3 to crush the garbage.

Next, the operation of the garbage crusher having such a structure will be described.

In FIG. 1, kitchen waste is introduced from an input port 10 and stored in a crushing chamber 6.

Next, the faucet of the faucet 13 is opened and water is allowed to flow.
Then, the motor 1 is started, and the rotary blade 3 is rotated via the rotary shaft 2.
To the rotating state.

As a result, the garbage in the crushing chamber 6 tries to rotate while being dragged by the rotary blade 3, but the garbage located near the tip of the rotary blade 3 is fixed to the first fixed portion projecting from the inner wall of the cylindrical hopper 4. The blade 7 can stop the rotation. Still rotating blade 3
In order to continue the high-speed rotation, the garbage is cut at the tip of the rotary blade 3.

The finely divided garbage falls to the bottom surface 14. Here, the convex portion 15 and the concave portion 1 provided on the bottom surface 14 are provided.

Then, the finely crushed garbage is discharged into the drain hole 18.
Alternatively, it flows into the pulverized material inflow chamber 8 through the gap 19 and is discharged to the outside through the discharge pipe 9 together with water.

As described above, the garbage put into the crushing chamber 6 is first roughly crushed by the interaction between the first fixed blade 7 and the rotary blade 3. When the rotary blade 3 is finely divided to a certain size, it is finely pulverized by an interaction between the convex portion 15, the concave portion 16 or the notch 17 provided on the bottom surface 14 and the rotary blade 3.

This makes it possible to stably pulverize the garbage that is to be processed.

Here, the convex portion 15 provided on the bottom surface 14,

The rotary blade 3 is easily bent by the reaction force received from the garbage. In particular, the rotary blade 3 is made of a chain member such as a roller chain or a chain, a wire or nylon,
In the case of a flexible body such as a rope, or an elastic body such as rubber or a spring (hereinafter, all of them are referred to as a flexible body in a broad sense), the bending becomes large, and as a result, the flexible body is formed. Garbage tends to accumulate on the bottom surface 14 near the rotation axis 2 of the rotary blade 3. Therefore, if the bottom 14 is formed into a shape (umbrella-shaped) whose central portion is raised, the garbage in the vicinity of the rotating shaft 2 is swept out to the tip of the rotating blade 3 by the rotating blade 3 and finely pulverized as described above. It flows out of the grinding chamber 6.

The shorter the distance between the bottom surface 14 and the lowermost rotary blade 3, the more the rotary blade 3 and the convex portion 15, the concave portion 16,
Since the interaction with the notch 17 is strengthened, the garbage is crushed more finely, and the fiber material and the like are easily cut. If the distance between the rotary blade 3 located at the lowermost stage (when the number of rotary blades is one, the rotary blade becomes the rotary blade located at the lowermost stage) and the bottom surface 14 is 10 mm or less, sufficient pulverization is sufficient. The effect of can be obtained.

Then, as shown in the present embodiment, the concave portion 16 of the bottom surface 14 is formed by superimposing the plate with the notch and the plate without the notch to form the bottom surface 14. Time and cost can be reduced.

In the present invention, the projection 15 and the depression 1
6 and the notch 17 need only be formed in at least one place. In addition, it is not necessary that all of the convex portion 15, the concave portion 16, and the notch 17 are formed, and any one of them may be formed. However, it is preferable that all of these types and a large number of them be formed, since the pulverization efficiency can be greatly improved.

Further, if a gap 19 is formed between the inner wall of the hopper 4 and the bottom surface 14, the drain hole 18 may not be provided. Conversely, if the drain hole 18 is formed, the gap 19 may be formed. It is not necessary.

In the case where the notches 17 are formed at a plurality of locations, the intervals may not be constant.

(Embodiment 2) FIG. 2 is a cutaway perspective view showing the internal structure of a crusher according to Embodiment 2 of the present invention.

In the crushing apparatus of the present embodiment, an annular second fixed blade 20 having irregularities formed inside is provided on the outer periphery of the rotation orbit of the rotary blade 3. Note that, unlike the case shown in the first embodiment, the convex portion 15 and the concave portion 1
6, the notch 17 and the drain hole 18 are not formed.

Next, the operation of the garbage crusher having such a structure will be described.

[0049] Kitchen waste is charged from the charging port 10 and stored in the crushing chamber 6. Next, the faucet of the faucet 13 is opened and water is allowed to flow. Then, the motor 1 is started, and the rotary blade 3 is rotated via the rotary shaft 2.

Then, the garbage in the crushing chamber 6 rotates while being dragged by the rotary blade 3, and the second fixed blade 2 is rotated by centrifugal force.
It is pressed to 0 and rubbed. Nevertheless, the rotary blade 3 is finely pulverized by the interaction between the rotary blade 3 and the second fixed blade 20 in order to continue high-speed rotation.

The finely pulverized kitchen waste flows into the pulverized material inflow chamber 8 through the gap 19 and is discharged to the outside through the discharge pipe 9 together with water.

As described above, according to the present embodiment, the garbage is finely crushed by the interaction between the rotary blade 3 and the second fixed blade 20, so that the garbage to be processed can be finely crushed stably. It is possible to do.

(Embodiment 3) FIG. 3 is a cutaway perspective view showing the internal structure of a crusher according to Embodiment 3 of the present invention.

The crushing apparatus of the present embodiment has a disk 21 attached to the rotating shaft 2 and rotated by the rotation of the rotating shaft 2 instead of the bottom surface 14 (FIGS. 1 and 2) described above. A crushing part 22 rotatably attached is provided. Therefore, the crushing part 22 revolves around the rotation axis 2 by the disk 21,
Due to the centrifugal force due to such revolving motion and the impact received from the inserted garbage, it rotates irregularly.

The second embodiment described in the second embodiment
Fixed blade 20 is provided.

Next, the operation of the kitchen crusher having such a structure will be described.

[0069] Kitchen waste is introduced from the introduction port 10 and stored in the crushing chamber 6. Next, the faucet of the faucet 13 is opened and water is allowed to flow. Then, the motor 1 is started, and the rotary blade 3, the disk 21, and the crushing unit 22 are rotated via the rotary shaft 2.

Then, the garbage in the crushing chamber 6 is cut by the rotating blade 3 rotating at a high speed and roughly crushed. Then, the roughly crushed garbage falls on the rotating disk 21 and is pressed against the second fixed blade 20 by centrifugal force to be rubbed.
Here, since the crushing unit 22 is rotating at high speed on the disk 21, the garbage is gradually shaved by the crushing unit 22 and the second fixed blade 20.

The finely crushed garbage flows into the crushed material inflow chamber 8 from the gap 19 and is discharged to the outside through the discharge pipe 9 together with water.

As described above, according to the present embodiment, the crushing section 22 provided on the disk 21 on which
Is finely pulverized by the interaction with the fixed blade 20, so that it is possible to stably perform fine pulverization of kitchen garbage as a processed material.

(Embodiment 4) FIG. 4 is a cutaway perspective view showing the internal structure of a crusher according to Embodiment 4 of the present invention.

In FIG. 4, the point that the crushing device is not fixed to the sink provided with the faucet is described in FIG.
~ 3.

In the crushing apparatus described in the first to third embodiments, kitchen garbage is treated, but in the present invention,
For example, the present invention can be applied to pulverization in which a material other than kitchen waste such as a foam tray or a plastic bottle is processed.

When crushing other than kitchen garbage, a mechanism for fixing to a sink is of course unnecessary.

Next, the operation of the crusher having such a structure will be described.

In FIG. 4, foamed trays, plastic bottles, and the like, which are pulverized materials, are charged through the charging port 10 and stored in the pulverizing chamber 6.

Next, the motor 1 is started to rotate the rotary blade 3 via the rotary shaft 2.

As a result, the foam tray and the PET bottle in the crushing chamber 6 try to rotate while being dragged by the rotary blade 3, while the foam tray and the PET bottle located near the tip of the rotary blade 3 are cylindrical hoppers. The rotation is stopped by the first fixed blade 7 protruding from the inner wall of the fourth fixed blade 4. Even so, since the rotary blade 3 continues to rotate at a high speed, the foaming tray, the plastic bottle, and the like are cut at the tip of the rotary blade 3.

The finely foamed trays and PET bottles fall to the bottom surface 14. Here, the rotation is stopped by the convex portion 15, the concave portion 16, or the notch 17 provided on the bottom surface 14, and the powder is further pulverized by the rotary blade 3 which continues to rotate at high speed.

Then, the finely pulverized foam tray or PET bottle is sent to the pulverized material inflow chamber 8 through the gap 19.

As described above, the foaming tray, the plastic bottle and the like put into the crushing chamber 6 are first roughly crushed by the interaction between the first fixed blade 7 and the rotary blade 3. Then, when the size is reduced to a certain size, the convex portion 1 provided on the bottom surface 14 is formed.
5, the pulverization is performed by the interaction between the recess 16 or the notch 17 and the rotary blade 3.

As a result, it is possible to stably pulverize the foamed trays and PET bottles to be processed.

Here, the convex portion 15 provided on the bottom surface 14,
If an edge is formed in the concave portion 16 and the notch 17, the convex portion 1 can be formed.
5, the interaction between the concave portion 16 or the notch 17 and the rotary blade 3 becomes stronger, so that the pulverization time is shortened and the pulverization efficiency can be improved.

The recess 16 provided on the bottom surface 14 is
If it is formed so as to spread outward in the radial direction, finely pulverized foam trays, plastic bottles, and the like are easily discharged from the gap 19.

It is to be noted that the first fixed blade 7 is
6 or the cutout 17, the foam tray or the plastic bottle receives the interaction of the rotary blade 3, the first fixed blade 7, the convex portion 15, the concave portion 16 or the cutout 17. As a result, the pulverization efficiency can be further improved.

Here, the rotary blade 3 easily bends due to gravity. Particularly when the rotary blade 3 is a flexible body such as a chain or a wire, the bending is large, and the bottom surface 1 near the rotary shaft 2 is large.
Foam trays, PET bottles, and the like are likely to accumulate on the top 4. Therefore, if the bottom surface 14 is formed into a shape (umbrella shape) in which the center portion is raised, the foaming tray and the plastic bottle near the rotating shaft 2 are swept out to the tip of the rotating blade 3 by the rotating blade 3, and as described above. Is finely ground.

The shorter the distance between the bottom surface 14 and the lowermost rotary blade 3, the more the rotary blade 3 and the convex portion 15, the concave portion 16,
Since the interaction with the notch 17 is strengthened, the foam tray, the PET bottle, and the like are more easily pulverized. In addition, the rotary blade 3 located at the lowermost stage (when the number of rotary blades is one, the rotary blade becomes the rotary blade located at the lowermost stage) and the bottom surface 14
If the distance from the substrate is 10 mm or less, a sufficiently fine pulverizing effect can be obtained.

When the recessed portion 16 of the bottom surface 14 is formed by superimposing the notched plate and the not-formed plate, the time and cost for manufacturing the bottom surface 14 can be reduced. Will be possible.

In the present invention, the projection 15 and the depression 1
6 and the notch 17 need only be formed in at least one place. In addition, it is not necessary that all of the convex portion 15, the concave portion 16, and the notch 17 are formed, and any one of them may be formed. However, it is preferable that all of these types and a large number of them be formed, since the pulverization efficiency can be greatly improved.

If a gap 19 is formed between the inner wall of the hopper 4 and the bottom surface 14, the drainage hole 18 may not be provided. Drainage treatment such as rain when placed is smooth.

In the case where the notches 17 are formed at a plurality of positions, the intervals may not be constant.

The processed material such as the foamed tray and PET bottle is naturally dropped or moved to the crushed material inflow chamber 8 by a blower (not shown) or the like, and is discharged from the discharge pipe 9 to the outside.

[0083]

As described above, according to the present invention, there is obtained an effective effect that it is possible to stably pulverize a processed product.

As a result, an effective effect of preventing the pulverized material from being clogged when discharged from the pulverization chamber can be obtained.

Further, if edges are formed in the convex portions, concave portions and notches, the interaction with the rotary blade is further strengthened, so that the pulverization time can be shortened and the pulverization efficiency can be improved. Effective effects can be obtained.

If the recess is formed so as to spread outward in the radial direction, an effective effect that the finely pulverized processed material is easily discharged from the gap can be obtained.

If the first fixed blade is disposed directly above the convex portion, the concave portion or the notch, the processed object can be rotated by the rotating blade, the first fixed blade and the three members of the convex portion, the concave portion or the notch. Since it is easy to receive the action, an effective effect that it is possible to further improve the pulverization efficiency is obtained.

If the central portion of the bottom plate is formed in a raised shape, the processed material near the rotating shaft is swept to the tip of the rotary blade, so that the processed material hardly accumulates on the bottom plate near the rotating shaft of the rotary blade. Effective effects can be obtained.

If the distance between the bottom plate and the lowermost rotary blade is set to 10 mm or less, the interaction between the rotary blade and the convex portion, the concave portion or the notch is strengthened, so that the processed material can be finely and easily pulverized. An effective effect is obtained that is possible.
