Description

A kind of hammer crusher

Technical field:

The present invention relates to a kind of hammer crusher.

Background technology:

Hammer mill mainly relies on percussion to crush building stones, shattering process is, its building stones enter in disintegrating machine, it is subjected to the impact of the tup that high speed is turned round and crushes, breaked building stones obtain kinetic energy at tup, rush at the counterpunch board in broken casing at a high speed, meanwhile building stones mutually clash into, repeatedly crushed, building stones less than broken casing discharging opening gap, discharge from discharging opening, indivedual bigger building stones, again through the impact of tup in broken casing, extrude and be broken, building stones are extruded in tup gap, thus obtain the product of desired particle size.

Operationally, the impact force of counterpunch board is easily made broken casing produce vibrations, long-term aggravation counterpunch board and the damage of broken casing in the past to existing hammer mill by building stones.

Rotor structure in existing hammer mill generally includes main shaft, end plate, hammer dish and tup, end plate, between hammer dish and tup by integrally welded structure, after tup is lost, need the whole rotor of integral replacing, replacement cost is high, and waste of material is serious.

Therefore, necessary prior art improves to solve the deficiency of prior art.

Summary of the invention:

The present invention is in order to solve the problem of above-mentioned prior art existence and to provide a kind of hammer crusher.

The technical solution adopted in the present invention has: a kind of hammer crusher, including the broken casing with rubble chamber, also include counterpunch board, pull bar, damping spring, clamp nut, draw-bar seat and rotor, three described draw-bar seats are fixedly connected on the lateral wall of broken casing, three counterpunch boards are all hinged on the sidewall in broken casing rubble chamber, pull bar one end is articulated with on counterpunch board, the other end passes on the sidewall of broken casing and is arranged on draw-bar seat, clamp nut is threaded on pull bar, damping spring is sheathed on pull bar and one end is connected on broken casing, the other end is connected on draw-bar seat, rotor rotates and is located in broken casing；

Described rotor includes rotating shaft, connecting tube, hammer dish, end plate, bar, tup and bearing pin, described connecting tube is connected in rotating shaft, two end plates are fixed on the two ends of connecting tube, some hammer dishes mutually being fixed in connecting tube and between two end plates the most across a certain distance, bar and bearing pin are all connected on described end plate and hammer dish along the axial direction of rotating shaft, some tups are sheathed on bearing pin mutually across a certain distance, and each tup is respectively positioned between adjacent two hammer dishes.

Further, described end plate is provided with the first slot, and hammer dish is provided with the second slot connected with described first slot, and bar is connected on end plate and hammer dish by first and second slot.

Further, the sidewall of described second slot is provided with positioning boss, and bar sidewall is provided with the detent suitable with described positioning boss.

Further, on described end plate sidewall and be positioned at the first slot-side and be provided with latch segment.

Further, described end plate is provided with the first pin shaft hole, and hammer dish is provided with the second pin shaft hole connected with described first pin shaft hole, and bearing pin is connected on end plate and hammer dish by first and second pin shaft hole.
