Abstract

The utility model discloses fine crushing hammer type grinder rotor assembly which comprises a driving wheel, bearings, a main shaft, turnplates and a hammer head. The bearings which are arranged at both ends of the main shaft are big clearance bearings, and hammer shafts are arranged on the turnplates. The hammer head is arranged between two adjacent turnplates and rotate along the hammer shafts. An isolation cover is arranged on the main shaft among the turnplates. Rotors of the utility model are stable and no vibration when in high speed rotation, and a plurality of turnplates are arranged on the main shaft, which increases the effective length of the rotors and improves the working efficiency by 50 percent. The hammer heads can rotate along the hammer shafts, which have the advantages of strong withdrawing capability when in operation, long service life and easy replacement.

Description

Beater grinder rotor assembly in small, broken bits

Technical field

The utility model belongs to materials crusher tool technical field, especially relates to a kind of beater grinder rotor.

Background technology

Beater grinder is widely used in material grinding such as shale, gangue, existing its rotor of beater grinder in small, broken bits is easy to generate vibrations when running up, cause body to damage and noise pollution, so the speed of this beater grinder operation in small, broken bits can not be too high, inefficiency, and pulverizer hammer is to be fixed on the rotating disk, can only can not freely rotate with dial rotation, damage easily, service life is short, changes inconvenient.

Summary of the invention

The beater grinder rotor assembly in small, broken bits that the technical problems to be solved in the utility model provides and a kind ofly runs up, fault rate is low.

For solving the problems of the technologies described above, the utility model comprises drive, bearing, main shaft, rotating disk and tup, the bearing that its design feature is provided in a side of the main shaft two ends is big play bearing, rotating disk is provided with hammer shaft, tup is located between adjacent two rotating disks and can rotates along hammer shaft, and the main shaft between rotating disk is provided with separation sleeve.

As to improvement of the present utility model, be provided with 3 hammer shafts on the rotating disk at least.

As to further improvement of the utility model, be provided with 8 rotating disks on the main shaft at least, the 1-1.8 that this rotating disk group length is a disk diameter is doubly.

The beneficial effects of the utility model are: the utility model main shaft two ends are provided with big play bearing, be provided with separation sleeve between rotating disk, rotor is steady and shockproof when running up, a plurality of rotating disks are installed on the main shaft, have increased the effective length of rotor, can increase work efficiency 50%, tup can rotate along hammer shaft, deformability is strong during operation, the long service life of tup, and change easily.
