The T-shaped block is used for preventing the material from blocking the T-shaped groove in the crushing process and preventing the blockage in the process of adjusting the crushing cutter.

The utility model discloses a T type groove can restrict crushing sword and can only remove about in the installed part, only needs the installation crushing sword that a bolt just can be stable this moment. The utility model discloses an actual length of smashing the sword can select as required, and this is just so feasible the utility model discloses a more nimble, the different crushing sword of optional usefulness. When the length of the crushing knife is fixed, the distance between the crushing knife and the body can be adjusted. The crushing cutter with the fixed length has the advantages that a certain amount of crushing cutters can be produced in batches, and the crushing cutters can be conveniently and timely replaced when being used at ordinary times. And adjust the crushing cutter subassembly with the different distances of body inner wall, the crisscross distribution of length also can make crushing effect better.

The utility model discloses a have access hole and access door on the body, the position of access hole can be so that install and change easily at epaxial crushing sword of smashing. For the installation of the access door, the same applies as usual in the prior art, which for reasons of space is not described here. And the installation of the access door is shown schematically in the drawings. The access door not only conveniently changes crushing sword, can also carry out manual clearance from access door to the sieve.

The utility model has the advantages that:

the utility model has simple structure and convenient operation; the utility model can be easily disassembled from the mounting part, and the disassembly is rapid and rapid, and a new crushing knife can be directly mounted, thereby greatly reducing the time for maintaining and replacing the worn crushing knife; the utility model discloses a smash the crushing sword of the removable different length models of sword, make the utility model discloses use more in a flexible way.
