Abstract

The utility model relates to the technical field of a crushing system for a hammer-type crusher underground a coal mine, and in particular relates to an anti-falling hammer body component for a crusher. The hammer body component is composed of a hammer body, a hammer head and a connecting bolt, and is characterized in that the hammer head is in bolt-type connection with the hammer body; the hammer body is used for limiting the hammer head, so as to reduce the vibration amplitude of the hammer head in actual work; meanwhile, the hammer head and the hammer body are connected and fixed through the connecting bolt, and bolt pre-tightening force forms an included angle with an acting direction of the hammer head, so as to alleviate adverse effect of vibration on bolt connection. The anti-falling hammer body component correspondingly solves a problem of hammer head falling through two measures, and according to the size of a crushing cavity, the volume of the hammer body is properly increased and the revolving impact force of the hammer body can be correspondingly increased, thus rotation blocking problem of a hammer shaft can be solved. The anti-falling hammer body component is reasonable in structure, and not only is the revolving impact force of the hammer head component increased, but also a problem that a firm piece becomes loose is well solved.

Description

Disconnecting preventing hammer body assembly for disintegrating machine

Technical field

The utility model relates to the technical field of hammer mill crushing system under coal mine, specifically disconnecting preventing hammer assembly for a kind of disintegrating machine.

Background technology

Along with the modernization of coal industry, there is major transformation in coal winning technology, and caving coal technology has obtained the application and development of science.But Sub-Level Caving very easily forms blocks, when working face runs into tomography, block rock mass increases.Lumped coal and block rock mass all can produce the destruction of forms such as touching, hit, pound to transporting equipment, therefore need crushing mechanism to carry out fragmentation to blocks.Hammer body assembly is the chief component of underground crusher, for broken block.Easily there is tup obscission in existing hammer body modular construction, and hammer body revolution impulsive force is not enough in long-term work, and when running into solid rock, being prone to cannot broken situation, causes normal production of hammer axle stall phenomenon impact.

Summary of the invention

The purpose of this utility model is to provide a kind of disconnecting preventing hammer body assembly, to overcome existing hammer body assembly, tup easily occurs comes off, hammers into shape the problems such as axle stall.

The technical scheme that the utility model adopts is: tup adopts bolt-type to connect with hammer body, and hammer body, to the effect of tup limited location, reduces the Oscillation Amplitude of tup in real work; Use attachment bolt that tup and hammer body are connected and fixed, bolt pretightening and tup acting direction form angle, have reduced the illeffects of vibration to bolt-connection simultaneously.By above-mentioned two kinds of measures, the tup problem of coming off has obtained corresponding solution.According to the size of crushing chamber of crusher, suitably increase the volume of hammer body, hammer body revolution impulsive force increases thereupon, and hammer axle stall problem is solved.The utility model is rational in infrastructure, has both increased Hammer head assembly revolution impulsive force, has well solved again firm loosening problem.

The utility model has the advantages that: crushing effect is good, simple in structure, it is firm, applied widely to connect.

Accompanying drawing explanation

Below in conjunction with accompanying drawing and specific embodiments, the utility model is described in further detail:

Fig. 1 is front view of the present utility model;

Fig. 2 is default view of the present utility model.

In figure: 1, tup, 2, attachment bolt, 3, hammer body.

The specific embodiment

As shown in Fig. 1～2, disconnecting preventing hammer body assembly is comprised of tup 1, attachment bolt 2, hammer body 3.

In actual use, tup 1 adopts bolt-type to connect with hammer body 3, and the 1 limited location effect of 3 pairs of tups of hammer body reduces the Oscillation Amplitude of tup 1 in real work; Use attachment bolt 2 that tup 1 and hammer body 3 are connected and fixed, bolt pretightening and tup 1 acting direction form angle, have reduced the illeffects of vibration to bolt-connection simultaneously.According to the size of crushing chamber of crusher, suitably increase the volume of hammer body 3, hammer body 3 revolution impulsive forces increase thereupon, and hammer axle stall problem is solved.

Claims

1. a disconnecting preventing hammer body assembly for disintegrating machine, is characterized in that: tup (1) adopts bolt-type to connect with hammer body (3), and hammer body (3), to tup (1) limited location effect, reduces the Oscillation Amplitude of tup (1) in real work; Use attachment bolt (2) that tup (1) and hammer body (3) are connected and fixed, bolt pretightening and tup (1) acting direction forms angle, reduces vibration to bolted illeffects simultaneously.
