This embodiment also includes an electric motor connected to the main shaft 16 through a fluid coupling.

The working principle is as follows: when the material crusher is used, materials enter a crushing cavity from a feeding hole, a motor drives a main shaft 16 to rotate at a high speed through a hydraulic coupler, the materials flying into the crushing cavity from the right upper side of a machine shell are impacted at a high speed by a hammer head 6 rotating along with the main shaft 16, the materials are impacted and crushed, kinetic energy is simultaneously obtained to impact a counterattack plate or an equalizing plate located on one side of the feeding hole at a high speed, and the materials are repeatedly crushed into qualified particle sizes in the crushing cavity under the actions of hammering, shearing, grinding, extrusion among the materials and the like and are finally discharged from a discharging hole.

Because the top impact plate 1 has a smooth impact surface, when the hammer 6 impacts materials and the materials rebound to the top impact plate 1, the materials are only impacted, namely the materials are only impacted and broken into small particles in the top impact plate assembly stage; the middle impact plate 4 is provided with crushing teeth, and materials are further ground under the shearing, extrusion and grinding actions among the crushing teeth on the hammer 6 and the middle impact plate 4 and the mutual impact action among other materials when in the middle impact plate assembly stage; when the plate assembly is leveled down, the material is beaten and crushed again, and finally the particle size required by discharging is discharged. Compared with the crusher which has the double functions of striking by the hammer 6 and shearing and grinding the crushing teeth when materials enter the crushing cavity in the prior art, the utility model firstly strikes and crushes the materials into small particles in the stage of pushing the counterattack plate, thereby greatly improving the crushing effect of the middle counterattack plate 4 on the materials; and because the stroke of material in broken intracavity is shorter, in order to guarantee ejection of compact granularity and qualification rate, set up lower levelling plate 5 again and strike the breakage once more to the material.

The utility model discloses in, main shaft 16 can be to two orientations rotation of turning over, and the both sides of feed inlet all are equipped with top counterattack board subassembly, well counterattack board subassembly 2 and lower average board subassembly 3, consequently can regularly change main shaft 16's direction of rotation to guarantee that the degree of wear of tup 6 both sides is unanimous, be favorable to improving the life of tup 6, reduce the frequency of maintenance, change spare part, thereby alleviate artifical intensity of labour greatly.

The utility model has a crushing ratio of 20-25, and when in use, different linear velocities (generally 50-62 m/s) can be selected according to different material and discharging particle sizes; the materials in the crushing cavity do not need to be cleaned manually, and the blockage of the materials can not be caused.

While embodiments of the invention have been described above, the above description is illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the illustrated embodiments.
