Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a shell liner in which materials to be crushed such as various kinds of waste inputted from the upper opening of a cylindrical shell are fixed inside the shell, a breaker liner provided on the outside of the rotating shaft, The present invention relates to a crusher that crushes particles using a grinder.

In the above crusher, the grinder is attached to a rotor plate attached to a rotating shaft via a link mechanism. In addition, this link mechanism consists of a pair of links for each grinder, and the end of one link is attached to a ring rotor rotatably attached to a rotor plate, and this rotor is rotated by a hydraulic jack or the like. This mechanism operates the link mechanism to move the grinder forward and backward in the radial direction.

In such a conventional adjustment device, a large hydraulic jack is provided on the rotor, resulting in an increase in the size of the rotor. Therefore, when installed in a small crusher, the problem arises that the rotor portion becomes large and the crushing chamber becomes small.

The purpose of this invention is to solve the problems of conventional crushers as described above, and the radial position of the grinder can be adjusted by adjusting the link mechanism without increasing the rotor size. It is.

That is, this invention has a breaker liner attached to a rotating shaft provided at the center of a cylindrical shell with a shell liner fixed inside.
In a crusher that has a grinder that is attached to the grinder so that it can move forward and backward using a link mechanism, one link of the link mechanism that supports the breaker liner is made telescopic using a screw jack mechanism, and since the link itself is telescopic, another link rotor or Since there is no need for a hydraulic jack or the like to drive this, the crushing chamber does not become smaller even when installed in a small crusher.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The adjustment device of the present invention will be described in detail below based on an embodiment shown in the accompanying drawings.

In the figure, 1 is a cylindrical lower shell, 2 is an upper shell fixed to the upper part, and this shell 2 has a shallow tapered shape with a wider upper part and an opening at the upper end as an input port. Further, a large number of shell liners 3.4 are fixed inside these shells 12, and these shell liners 3.
．． 4 is made by arranging thick and thin pieces in an appropriate order to create unevenness.

Reference numeral 5 denotes a vertical rotation shaft provided at the center, which is rotated by a drive device provided at the bottom, although not shown.

A rotor 6 is fixed to the upper end of the rotating shaft 5, and a plurality of pairs of upper and lower breaker joints 7 are connected to the shaft 8 above and below the rotor 6.
A breaker liner 9 is rotatably attached between the outer ends of each joint 7.

A pair of upper and lower disc-shaped rotors 10.11 are fixed to the upper and lower ends of the rotating shaft 5, a rotor ring 12 is fixed to the outer periphery of the rotor 10, and a rotor liner 13 is fixed to the outer periphery of the rotor 11.

Reference numeral 14 denotes a plurality of shafts fixed between the upper and lower rotors 10 and 11, and to this shaft 14, one telescopic link 15 having a screw jack mechanism and the other link 16 are rotatably attached. be.

The link 15 has a female thread 18 formed inside a main body 17 which is rotatably attached to a shaft 14 as shown in FIG. A male thread 21 on the outside of the reciprocating member 20 is screwed into a female thread on the inside of this screw tube 19. A ring 22 is fixed to the outer end of the screw 19, and a plurality of notches are provided on the outside of this ring 22. The screw tube 19 is rotated by engaging the locking piece of the wrench.

The thread directions of the female thread 18 and the male thread 21 are opposite to each other, and the upper and lower annular portions of the joint 24 are rotatably fitted above and below the shaft 23 fitted into the shaft hole at the outer end of the reciprocating member 20. A grinder 25 is fixed to 24 with a plurality of pins. Also, the link 16 is made up of two upper and lower links.
The outer end of 6 is also rotatably attached above and below the shaft 23.

The crusher having the adjustment device of the present invention has the above-mentioned configuration, and the material to be crushed is thrown into the shell 2 from the input port at the upper end and is blown away by the breaker liner 9 that rotates together with the rotating shaft 5 to the inside of the shell 1. It collides with the liner 4, is crushed, moves downward, and is further finely crushed by the grinder 25 and the liner 3.

Therefore, by adjusting the gap between the grinder 25 and the liner 3, the size of the crushed material changes.
By engaging the retaining piece of the spanner with the notch of
4. The distance between the grinder 25 and the liner 3 is adjusted by changing the distance between the grinder 25 and the liner 3. As described above, the link 15 that supports the grinder 25 is made of a screw jack type telescoping type, so it is not necessary to It is much smaller than the one that uses a separate hydraulic jack, and there is no risk of reducing the capacity of the crushing chamber even if it is installed in a small crusher.

In the embodiment, a screw tube 19 having internal and external screws is screwed between the main body 17 and the retractable member 2o to increase the amount of movement of the retractable member 2o due to the rotation of the screw 19. A male screw may be screwed into the advancing/retracting member 20 so that the female screw is rotatable and moves forward and backward together. Further, the link 16 may also be made of a screw jack type that can be expanded and contracted.
