For achieving the above object, the technical scheme of the utility model is: a kind of pulverizer comprises the housing of scroll casing shape; Rotating shaft, motor, base, said housing and motor are fixed on the base, and said lower part of frame is provided with discharge nozzle; Said housing rear side is provided with a centre bore, and rotating shaft is contained on the centre bore of said housing rear side, and an end of rotating shaft stretches in the housing; The other end of rotating shaft is connected with motor through transmission mechanism, and said housing front side is provided with opening, and end cap is housed on the opening; One side and the described housing of end cap are articulated, and the opposite side of end cap and described housing fix through bolt, and it is charging hole that end cap is provided with a centre bore; The cutterhead that the interior end of housing is equipped with a circle is stretched in rotating shaft; Be fixed with a plurality of rotation cutting knifes that along the circumferential direction are spaced and parallel with shaft centerline on the cutterhead, end cap be provided with cutterhead on rotate the fixed cutting tool that cutting knife matches, the outside of cutterhead is provided with a screen pack; The two ends of screen pack are stuck between said housing and the end cap, the external communications discharge nozzle of screen pack.

Further, the outward flange of said housing front openings is equipped with sealing ring, strengthens the sealing between end cap and the housing.

Further, the middle part of said rotating shaft is provided with axle bed, and rotating shaft is connected through bearing with the centre bore of axle bed with said housing rear side, and the rear portion of rotating shaft is connected with the output shaft of motor with belt gear through belt pulley, and the running of rotating shaft is more steady like this.

Further, described rotation cutting knife rear portion is provided with screw thread, and cutterhead is provided with installing hole, and the installing hole that the rotation cutting knife passes cutterhead is fixed on the cutterhead with nut, the replacing of the feasible rotation of this structure cutting knife and easy to maintenance.

Further, described fixed cutting tool rear portion is provided with screw thread, and end cap is provided with installing hole, and the installing hole that fixed cutting tool passes end cap is fixed on the end cap with nut, and this structure makes the replacing of fixed cutting tool and easy to maintenance.

The utility model is located on the end cap owing to charging hole; Lower part of frame is provided with discharge nozzle; Just shear each other and can pulverize graininess or block potato powder through rotation cutting knife on the cutterhead in the housing and the fixed cutting tool on the end cap; So compact conformation, owing to cutterhead quick rotation under motor and transmission mechanism drive, crush efficiency is very high simultaneously.

On the other hand, a side and the housing of end cap are articulated, and the opposite side and the housing of end cap fix through bolt, unclamp bolt and just can be easy to open end cap, open behind the end cap the cleaning of each part in the cleaning of material in the housing and the housing just very convenient.
