The material to be crushed M is positioned on the recess 11 so that it straddles the recess 11, and when in that state, it is struck by the striker 4, it is pushed into the recess 11, thereby effectively producing shearing action by the recess peripheral edge 11a to smoothly crush it.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal crusher for efficiently crushing crushed materials such as rocks, minerals and bulky waste.

[0002]

2. Description of the Related Art This type of horizontal crusher (hammer crusher) is described in Japanese Patent Application Laid-Open No. 61-187944 and the like. As shown in FIG. A rotor 3 fitted on the rotating shaft 2,
A plurality of strikers 4 (4
a, 4b) and regular openings 9 in the bottom of the casing 1
A supply port (inlet port) 5 on the side of the casing 1, a chute 6 inclined below the supply port 5, and a lower end of the chute 6 mounted on the receiving table 12. It has an anvil 7 placed.

In this horizontal crusher, the crushed material M supplied from a supply port 5 slides down on a chute 6 and is sent onto an anvil 7 to collide with a striker 4 rotating at high speed. . Then, after being subjected to the crushing action, it is repelled by the striker 4 and collides with the great 8, and further subjected to the crushing action.

[0004] By this crushing action, the crushed material M sufficiently crushed is discharged through the opening 9 of the great 8, and the crushed material M not sufficiently crushed is further struck by the striker 4. In response to the impact crushing action, it is subjected to the shearing action of the striker 4 and the grate 8 and crushed until it becomes fine. In this way, the supplied crushed material M is finely crushed, and the casing 1 is crushed through the opening 9.
It is discharged outside.

[0005]

In the above-mentioned horizontal crusher, the crushed material M is first subjected to the crushing action on the anvil 7, and the superiority of the shear crushing here greatly affects the overall crushing efficiency. Affect. However, the conventional anvil 7
Since the upper surface (the surface facing the rotating striker 4) is flat, a large resistance to the movement of the crushed material M on the upper surface cannot be expected, and the shearing action by the cooperation between the striker 4 and the anvil 7 is insufficient.

Further, in the horizontal crusher described in the above-mentioned publication, the striker 4 has a large striker 4a and a small striker 4a.
6B, the anvil 7 is formed with a cutout portion 20 through which the large striker 4a can pass, as shown in FIG. 6B. For this reason, since the crushed material M straddling the notch 20 of the anvil 7 is sheared and crushed by the large striker 4a, it is considered that the shearing efficiency is extremely high.

However, since the shear efficiency is extremely high, the anvil 7 is severely deformed and damaged, and the notch 2
The edge of 0 is immediately rounded and the shearing efficiency decreases, and furthermore, since the protrusions 21 at both ends of the notch 20 protrude from the cradle 12, the protrusions 21 easily drop down and the shearing efficiency decreases. In addition, there is a problem that the life of the anvil 7 is short. In addition, since the anvil 7 described in this publication has cutouts 20 on both sides thereof (left and right in FIG. 6B), if the shearing efficiency is reduced, the left and right sides are reversed and the other cutout 20 is used. This can extend the life, but the limit is to double the life. In addition, the instantaneous load at the time of shearing may be too large and the motor may stop.

[0008] It is an object of the present invention to improve the shearing action of a crushed material between a striker and an anvil.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is designed to increase the resistance of a crushed object on an anvil to movement. If the movement resistance increases, the crushed material of the shearing action between the striker and the anvil is difficult to move,
Its action is improved. Next, the present invention causes a phenomenon that the crushed material straddles the space even on the upper surface of the anvil,
This is to improve the shearing action.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As one embodiment of the present invention, a rotor is provided in a casing into which crushed material is put, and a striker is swingably mounted on the outer periphery of the rotor, and the rotating striker is used to rotate the striker. Shock crushing the crushed material, providing a great around the rotor through the anvil from the inlet of the crushed material, and crushing the initial of the crushed material by the anvil and the striker, and by the great and striker In a horizontal crusher that crushes the subsequent crushed material and discharges the crushed crushed material from the opening of the great, a configuration in which unevenness is formed on a surface (upper surface) of the anvil facing the rotating striker is provided. It was done.

If the surface of the anvil is uneven, the resistance to movement of the crushed material on the surface increases, and if the crushed material is located between the convex portions, it will straddle the convex portion.

If the above-mentioned irregularities reach the front surface of the anvil and have an edge formed by the edges of the upper surface and the front surface of the irregularities, the movement resistance is reduced, but the shearing action is caused by the edge edge (blade). improves. Irregularities are projections, protrusions, grooves,
It is formed by a recess or the like.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The horizontal crusher of this embodiment
As shown in FIG. 1, a rotating shaft 2 horizontally laid in a casing 1, a rotor 3 fitted on the rotating shaft 2, and a plurality of strikers 4 swingably mounted on the rotor 3. And a great 8 having a regular opening 9 at the bottom of the casing 1
And a supply port 5 on the side of the casing 1, a chute 6 arranged obliquely below the supply port 5, and an anvil 7 mounted on a receiving table 12 at the lower end of the chute 6. Things. The striker 4 has both a ring type shown in this figure and a hammer type not shown, but the circle drawn by the outermost end of the striker 4 is all designed to have the same radius.

The chute 6 has a concave portion 10 at its lower end, and the anvil 7 has concave portions 11 on both sides thereof (see FIG. 2). The recess 11 allows the anvil 7
Is formed on the surface, and the peripheral edge of the concave portion 11 becomes an edge 11a, so that the shearing action is performed smoothly. The recesses 11 are formed on both sides (left and right edges in FIG. 1) of the anvil 7, and are used upside down when the inside of the casing 1 is worn.

As shown in FIG. 1, the great 8 has a plurality of great bars 13 (13a, 13b, 13c) arranged in a circular arc around the rotor 3, and has a blockage which does not have an opening at first. It comprises a great bar 13a, a great bar 13b for forming the opening 9, and finally 13c without an opening. As shown in FIG. 3, the great bar 13 includes a long horizontal bar 14, a front projection 15 and a rear projection 16 which protrude in a comb-tooth shape in a direction perpendicular to the front and rear of the horizontal bar 14.
And blocks 17 located at both ends of the horizontal bar 14. By arranging these great bars 13a, 13b, 13c along the rotation direction of the rotor 3 with the projections 15 and 16 abutting on each other, a great 8 having openings 9 around the periphery is formed. The great bar 13 is arranged so that a predetermined gap, for example, a gap of 20 mm to 30 mm is formed between the great bar 13 and the striker 4 whose upper surface rotates.

This embodiment has the above configuration.
Explaining the operation, the crushed material M supplied (input) from the supply port 5 slides down on the chute 6 and the anvil 7
And subjected to the shearing and crushing action of the striker 4 and the anvil 7 rotating at high speed.

At this time, as shown in FIG. 4, the crushed material M is pressed against the concave portion 10 of the chute 6 and the concave portion 11 of the anvil 7 and is subjected to a shearing action. Further, since the crushed material M is pressed while straddling both the upper surface of the anvil 7 and the concave portion 11 thereof, the crushed material M is crushed on the upper surface, and further pressed downward in the concave portion 11,
The crushed material M is sheared (divided) by the edge 11a. Further, of the crushed material M, the portion crushed on the upper surface remains at that position, and the portion pressed downward by the concave portion 11 tends to move together with the striker 4, so that the edge 11a shears the crushed material M ( The dividing) operation is performed efficiently. Since the edge 11a is located around the concave portion 11, it receives more shearing action, and the shearing direction (left-right direction and front-back direction) is different, so that more efficient shearing action is performed.

By these shearing actions, crushed material M having relatively low strength, such as wood, is reliably sheared. In addition, it is difficult to say that the crushed material M having a relatively large strength such as a metal is surely sheared, but it is at least damaged.

Incidentally, as compared with the case where the concave portion 11 is not provided (flat), the crushed material M enters the concave portion 11, so that the pressing force (surface pressure) on the upper surface is increased,
It can be said that the shearing action of the crushed material M by the edge 11a is considerably large.

In the case where the crushed material M is oversized garbage, the oversized garbage is crushed in order to reuse resources, and metal garbage (for example, an iron plate or a motor outside a refrigerator) and soft garbage ( It is necessary to categorize the plastic inside the refrigerator, the vinyl sheet of the simple costume case) and the wooden waste (such as a chest of drawers).

For this purpose, it is necessary to finely crush the oversized refuse so that the refuse can be classified for each refuse. However, as in the case of refrigerators, it is difficult to smoothly classify both large garbage in which a foamed resin for heat insulation is adhered to an outer iron plate.

However, in this embodiment, as described above,
Due to the presence of the recess 11, the pressing force (surface pressure) on the upper surface of the anvil 7 is large, so that the iron plate to which the foamed resin is bonded is bitten into the anvil 7 (recess 11), and the material on the side other than the bitten material , For example, if the foam resin bites,
Only the iron plate moves easily together with the striker 4, and the iron plate and the foamed resin are easily removed.

The crushed material M subjected to the shearing action in the anvil 7 is repelled backward by the striker 4 and crushed by colliding with the great bar 13. Further, the crushed material M on the great 8 is caused by a collision with the striker 4, a collision with the great 8 after being repelled by the striker 4, and a shear between the striker 4 and the great 8. Crushed.

The crushed material M sufficiently crushed by these crushing actions is discharged through the opening 9 of the great 8, and the crushed material M not sufficiently crushed is
Furthermore, it is hit by the striker 4 and crushed until it becomes fine. In this way, the supplied crushed material M is finely crushed and discharged out of the casing 1 through the opening 9.

The recess 11 on the anvil 7 passes through the lower end of the chute 6 and leads to the recess 11 on the opposite side as shown in FIG. 5A, or does not pass as shown by the chain line in FIG. Alternatively, as shown in FIG. 7B, it can be formed not only on both sides of the anvil 7 but also at the center, and conversely, it can be formed only at the center. The unevenness on the anvil 7 is not limited to the one formed by the concave portion 11 but may be formed by the protrusion 18 as shown in FIG. 3C. In this case, as shown in FIG. Can also.

In the embodiment, the anvil 7 is not made to protrude from the cradle 12, but it may be made to protrude as shown in the above-mentioned publication (FIG. 6), and in this case, the notch 20 can be formed similarly. . Also, the striker 4 shown in FIG.
a, 4b, or the large striker 4a is the notch 2
Even those that fall into 0 can have irregularities formed on the upper surface of the anvil 7.

[0027]

As described above, the present invention increases the resistance of the crushed material to move on the anvil and causes a phenomenon in which the crushed material straddles the space on the anvil. It is possible to improve the initial crushing action that greatly affects the crushing efficiency of the entire crusher.
