Abstract

A fine coal crusher relates to a coal crushing device and is designed for solving the problems of short service life, high maintenance cost, great vibration and the like in a traditional fine coal crusher. The fine coal crusher comprises a machine body, wherein a bearing block is arranged on the machine body; a main shaft is mounted on the bearing block through a bearing; a disk is arranged on the main shaft; an annular shaft is mounted in an annular shaft hole of the disk; approximately-arc adjusting frames which correspond to each othere are arranged on two sides of the main shaft and the disk; wave plates are lined inside the adjusting frames; the adjusting frames are mounted on side covers through an upper adjusting frame and a lower adjusting frame; the side covers are fixed on the machine body; upper ports formed by the upper ends of two corresponding adjusting frames are feed openings; lower ports formed by the lower ends of the two corresponding adjusting frames are discharge openings; a hammer head is movably connected with one end of a hammer arm through a small shaft; the other end of the hammer arm is sleeved on the annular shaft; and a limiting lug boss is formed on the hammer arm. The fine coal crusher has the advantages of long service life, low maintenance expenses and small vibration.

Description

A kind of thin coal breaker

Technical field:

The utility model relates to a kind of broken coal device.

Background technology:

Existing thin coal breaker tup and hammerhead jib are one, and hammerhead jib is contained on the annulate shaft, does not have buffering when shortcoming is work, and is easy to wear, and service life is short, need integral replacing after the damage, and maintenance cost is high; Because the tup amplitude of oscillation there is not restriction, and the amplitude of oscillation is excessive, vibration is big in addition.

Summary of the invention:

Tup had cushioning effect when the utility model technical problem to be solved provided a kind of work, and not easy to wear, without integral replacing, maintenance cost is low after the wearing and tearing; And the tup amplitude of oscillation has certain limitation, and the amplitude of oscillation is little during work, vibrates little thin coal breaker.

It is that it also comprises body that above-mentioned purpose is achieved in that identical with prior art, and bearing block is arranged on the body, and main shaft is contained on the bearing block through bearing; Be fixed with several disks on the main shaft, have spacer to separate between the disk, be provided with several annulate shaft holes on the circumference of disk equably; The disk annulate shaft is equipped with annulate shaft on the hole; Be provided with the adjustment rack of the near-sighted arc of mutual correspondence in the both sides of main shaft and disk, adjustment rack the inside is lined with the wave plate, the bigger length with tup of the spacing between wave plate and the disk; Adjustment rack is contained on the side cover through adjusted frame and following adjusting bracket; Side cover is fixed on the body, and the suitable for reading of corresponding two adjustment racks upper end formation is dog-house, and the end opening that the lower end forms is a discharging opening; The one end flexible connection of different is tup passes through little axle and hammerhead jib, the hammerhead jib other end is sleeved on the annulate shaft.

In order to limit the amplitude that radially wobbles of hammerhead jib, reduce vibration, a boss of can on hammerhead jib, limiting.

End with main shaft during use is connected with motor with belt, when tup or glass wave plate one lateral wearing, can rotor reversed.

The utility model has the advantages that: therefore flexible owing to be to flexibly connect between tup and hammerhead jib two parts, cushioning effect is arranged, not easy to wear, and it is just passable only to change tup after the wearing and tearing, thus long service life not only, and maintenance cost is low; Radially wobble amplitude owing to have positive stop lug boss to limit it on the hammerhead jib again, so vibration is reduced.

Description of drawings:

Accompanying drawing is the structural representation of the utility model.

The specific embodiment:

With reference to accompanying drawing, it comprises body 4, and bearing block 11 is arranged on the body 4; Main shaft 12 is contained on the bearing block through bearing, is fixed with several disks 13 on the main shaft, has spacer to separate between the disk; Be provided with several annulate shaft holes on the circumference of disk equably, the disk annulate shaft is equipped with annulate shaft 10 on the hole, is provided with the adjustment rack 3 of the near-sighted arc of mutual correspondence in the both sides of main shaft and disk; The adjustment rack the inside is lined with wave plate 2; The bigger length with tup of spacing between wave plate and the disk, adjustment rack is contained on the side cover 6 through adjusted frame 5 and following adjusting bracket 14, and side cover is fixed on the body; The suitable for reading of corresponding two adjustment racks upper end formation is dog-house 1, and the end opening that the lower end forms is a discharging opening 16; Tup 7 flexibly connects through the end of little axle 8 with hammerhead jib 9, and the hammerhead jib other end is sleeved on the annulate shaft 10.

In order to limit the amplitude that radially wobbles of hammerhead jib, reduce vibration, the boss 15 of can on hammerhead jib, limiting.
