Abstract

The utility model relates to a crusher for making bricks with coal slack and breaking the coal, in particular to a centrifugal crank arm hammer piece crusher, which comprises a feed port 1, a machine box 2, a sieve plate 3, a crank arm 6 and a discharging port 7. A serrate plate 4 is positioned at interval in the inner side of the sieve plate 3; a serrate hammer piece 5 corresponding to the serrate plate 4 is positioned at the end section of crank arm 6; the sieve plate 3 and serrate plate 4 are fixed on the round ring 10. The beneficial effects of the utility model are: simple structure, low operational cost, large crushing rate and excellent crushing effect.

Description

The centrifugal tooth-like hammer leaf disintegrating machine of cranking arm

Technical field

The utility model relates to the disintegrating machine that is used for making coal gangue brick and coal crushing, particularly a kind of centrifugal tooth-like hammer leaf disintegrating machine of cranking arm.

Background technology

Making coal gangue brick is the environmental protection and energy-conservation industry that country helps.The method that at present mostly adopts a two-stage crushing to combine, one-level adopts hammer broken, secondary adopts roll-type or cage fragmentation, the broken operating cost height of these forms, crushing system accounts for 40% of production cost, easily overload, vibration equipment is big, and these crumbling methods all are the tangential directions of rotation to the active force of material, just can not fragmentation when material is not on the percussion face of rotation, and can stop up discharging channel simultaneously and influence crushing effect.

Summary of the invention

The technical problems to be solved in the utility model is to overcome the shortcoming that exists in the prior art, and a kind of rational in infrastructure, operating cost is low, the ratio of reduction is big, crushing effect is good centrifugal tooth-like hammer leaf disintegrating machine of cranking arm is provided.

The utility model is achieved in that a kind of centrifugal tooth-like hammer leaf disintegrating machine of cranking arm for this reason, it comprises charging aperture, cabinet, sieve plate, cranks arm, discharging opening, clear width at sieve plate is provided with castellated plates, be provided with and the corresponding profile of tooth hammer leaf of castellated plates in the end of cranking arm, sieve plate and castellated plates are fixed on the ring.The rotating shaft disc rotated, under action of centrifugal force, crank arm, the tangential direction extruding percussion in material in this point of hammer leaf, crank pin mating reaction is to castellated plates, the hammer leaf inclination angle increases, the area of hammer leaf percussion face increases, avoided raw material to rotate, can the material of coarsegrain repeatedly have been acted on simultaneously with hammer leaf.The interval of castellated plates and sieve plate is arranged, spilt the material that reaches granularity timely, effectively reduced obstruction, under action of centrifugal force, raw material material spilling hole to sieve plate in broken passage gathers, so just increased the impulsive force of hammer leaf to material, thereby improved the ratio of reduction of material, the structure of cranking arm is in operation and can swings, and has avoided the impact of bulk materials to transmission mechanism, cushioned the infringement of load, reduced vibrations machine.

The beneficial effects of the utility model are: rational in infrastructure, operating cost is low, the ratio of reduction is big, crushing effect is good.

The specific embodiment

With reference to the accompanying drawings, a kind of centrifugal tooth-like hammer leaf disintegrating machine of cranking arm, it comprises charging aperture 1, cabinet 2, sieve plate 3, cranks arm 6, discharging opening 7, clear width at sieve plate 3 is provided with castellated plates 4, be provided with and castellated plates 4 corresponding profile of tooth hammer leaves 5 in 6 the end of cranking arm, sieve plate 3 and castellated plates 4 are fixed on the ring 10.Rotating shaft 11 drives disks 9 and rotates, and under action of centrifugal force, cranks arm 6, hammer leaf 5, the tangential direction extruding percussion of crank pin 8 mating reactions in material in this point be to castellated plates.

Claims

A kind of centrifugal tooth-like hammer leaf disintegrating machine of cranking arm, it comprises charging aperture (1), cabinet (2), sieve plate (3), crank arm (6), discharging opening (7), it is characterized in that: the clear width at sieve plate (3) is provided with castellated plates (4), end in crank arm (6) is provided with and the corresponding profile of tooth hammer leaf of castellated plates (4) (5), and sieve plate (3) and castellated plates (4) are fixed on the ring (10).
