In the field of garbage crushing, the crusher mainly comprises a horizontal double-roller multi-cutter shearing crusher, a horizontal single-roller multi-cutter cutting crusher and a vertical shaft multi-chain hammer crusher. The principle of the horizontal double-roller multi-cutter shearing crusher is that a string of cutter heads with certain thickness are arranged on the double rollers, the cutter heads on the two rollers are mutually staggered, the cutter heads form a mutually meshed shearing state, notched material cutting spaces are distributed on the circumference of each cutter head at equal intervals, when the two cutter rollers roll oppositely, materials can be crushed or cut off and extruded into the material cutting spaces distributed on the cutter heads at equal intervals, and under the continuous rolling of the double rollers, the materials can downwards pass through the lower parts of the double rollers from the upper parts of the double rollers and then are thrown out, so that the crushing is finished. The principle of the horizontal single-roller multi-cutter cut-off crusher is that a series of cutter heads are arranged on a single roller, each cutter head is provided with a material cutting space with notches distributed at equal intervals, the cutter heads are staggered by a certain angle, the cutter heads are movable cutters, fixed cutters are arranged in the horizontal single-roller multi-cutter cut-off crusher, the movable cutters are meshed with the fixed cutters to play a shearing role when rotating, and materials are cut off and crushed when rotating through the movable cutters. Because the crushing knives of the crusher are integrated, the replacement and maintenance are not easy. The equipment can also cause more serious wearing and tearing and damage to the cutter head cutter tooth when long-term operation, just need demolish the equipment whole this moment, and a piece of cutter head is demolishd out, changes or restores and even scrap, causes very big maintenance and maintenance cost. The utility model discloses effectively solve breaker cutter head wearing and tearing and change and greatly reduced maintenance cost's problem.

As shown in fig. 1, the utility model provides a cutter head device is broken to cutter, cutter head device install in breaker box 3, wherein, cutter head device is broken to the cutter includes:

the tool apron 7, the appearance and centre hole of which adopt the multilateral shape, is installed on the forward rotation driving shaft 1 and the reverse rotation driving shaft 2;

the cutter teeth 8 and the cutter head crushing device of the shearing machine need to be assembled by a plurality of cutter teeth 8, and each cutter tooth 8 independently exists and can be detached;

fastening hardware for assembling the holder 7 with the cutter teeth 8.

In an alternative embodiment, the forward rotation drive shaft 1 and the reverse rotation drive shaft 2 are polygonal in shape so that the tool holder 7 is mounted on the forward rotation drive shaft 1 and the reverse rotation drive shaft 2.

A broken blade disc device of cutter installs on corotation drive shaft 1 and reversal drive shaft 2, and blade holder 7, sword tooth 8 are installed with components of a whole that can function independently assembly form, and corotation drive shaft 1 and reversal drive shaft 2 are installed in box 3. When the equipment runs for a long time and causes serious abrasion and damage to the cutter head, the whole disassembly is not needed, only individual abraded cutter teeth are required to be disassembled, the abrasion and the replacement of the cutter head of the crusher can be more convenient, and the maintenance cost can be reduced. The shearing type crusher can be understood that the power of the shearing type crusher drives the transmission shaft, and the transmission shaft drives the crushing cutter head on the shaft to rotate; the material that gets into broken storehouse by the feed inlet receives the adjacent knife face blade of moving sword or stationary knife to form the shearing, moves the sword knife tip and forms the shearing with spacer cylinder face or stationary knife, thereby the impact that the torsion or the speed difference of arbor formed reaches crushing effect with tearing, utilizes the impact and the shearing force of broken blade disc sword tooth to break into the particle size of great particle diameter material.

In an alternative embodiment, the knife holder 7 is mounted on a counter-rotating drive shaft with a knife spacer 6 between each knife device in each row.

In an alternative embodiment, the cutter spacer 6 is adjacent to the stationary knife 5, so that the cutter device 4 is fixed in position.

In an alternative embodiment, the fixed blade 5 is connected to the box 3.

A broken blade disc device of cutter is equipped with blade disc spacer 6 and stationary knife 5 between blade disc and the blade disc, and stationary knife 5 is connected with box 3, can make every blade disc device 4's rigidity.

In an optional embodiment, the tool apron 7 and the tool teeth 8 are positioned by adopting a key slot or a mortise and tenon structure.

In an alternative embodiment, the fastening hardware is a bolt, so that the tool holder 7 is fastened to the tool tooth 8.

In an alternative embodiment, the insert seat 7 and the cutter teeth 8 are made of a metal alloy steel.

In the description provided herein, numerous specific details are set forth. It is understood, however, that embodiments of the invention may be practiced without these specific details.
