Abstract
The utility model provides a jaw crusher for an underground coal mine. The existing jaw crusher for the underground coal mine is poor in continuous crushing performance; coal is easy to be accumulated at a crusher coal inlet and over-crushing is easy to form; quick-wear part costs are increased, crushing amount is reduced, and the utilization of the crusher is influenced due to frequent halt and maintenance. The jaw crusher for the underground coal mine comprises a crushing chamber body; one side inside the crushing chamber body is provided with a fixed crushing plate. The jaw crusher for the underground coal mine is characterized in that the other side of the crushing chamber body is provided with a striking hammer which moves along the vertical direction of the fixed crushing plate; the striking hammer is connected with a driving device. The jaw crusher for the underground coal mine has the advantages of crushing large block coal, being good in continuous crushing performance, enabling crushed products to be uniform in particle size, avoiding over-crushing and being convenient to integral dismounting and conveying.
Description
Technical field:
The utility model relates to a kind of coal mine equipment, is specifically related to a kind of underground mine use jaw crusher.
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.When the hardness f2 of coal, the intensity of coal is difficult for destroyed, Sub-Level Caving very easily forms bulk, when working face runs into tomography, biotite gneiss increases, lumped coal and biotite gneiss are all difficult for by elevating conveyor or transfer point, and transporting equipment are produced to the destruction of forms such as touching, hit, pound, and to downhole safety, transportation brings difficulty.Disintegrating machine is exactly that lumped coal and biotite gneiss is fully broken, makes it smoothly by elevating conveyor or transfer point, guarantees downhole safety transportation and produces.At present, the disintegrating machine using under coal mine, because working condition, the production capacity in each ore deposit are different, the type of disintegrating machine is different.Wherein using maximum is jaw crusher and hammer mill, although these disintegrating machines have been brought into play good fragmentation, in use also has some problems: (1), although jaw crusher can broken larger lump coal, continuous crushing is poor; Although hammer mill continuous crushing is better, the lumpiness size of broken coal has certain limitation, and disintegrating machine coal-in port place easily forms long-pending coal, and easily forms pulverizing.(2) 2 of jaw crusher crusher jaw plate intensity are large, not fragile, but lining plate replacing is frequent; hammer head of hammer crusher is fragile, changes inconvenience, has brought thus and has shut down frequently and keep in repair; cause consumable accessory expense to increase and crushing minimizing, affect disintegrating machine service efficiency.(3) supplementary structure of disintegrating machine is more complicated, to installation and maintenance, brings inconvenience, and when dismounting is transported, parts are easily lost.
Summary of the invention:
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of underground mine use jaw crusher, can broken larger lump coal, continuous crushing is good, broken after the epigranular of product, avoided pulverizing, and integral disassembly, assembly convenient transportation.
Above-mentioned object realizes by following technical scheme:
Underground mine use jaw crusher, comprise broken cavity, one side of described broken cavity the inside is installed stationary crushing plate, and the opposite side of described broken cavity is provided with the strike tup along stationary crushing plate movement in vertical direction, described strike tup connecting drive device.
Described underground mine use jaw crusher, described drive unit comprises drive motors, described drive motors connects flywheel by reductor, and the edge of described flywheel connects connecting rod by bearing pin, and described connecting rod is connected with described strike tup through fixed guide.
Described underground mine use jaw crusher, the inside of described fixed guide is provided with one group of ball.
Described underground mine use jaw crusher, is provided with liner plate on described stationary crushing plate.
Beneficial effect:
1. the utility model hits lumped coal and biotite gneiss by hitting tup, makes its fragmentation, and the flexible amplitude of hitting tup is large, can broken larger lump coal, and the generation of simultaneously avoiding disintegrating machine coal-in port place easily to form long-pending coal and cross the phenomenons such as pulverizing.
2. the utility model, for common jaw crusher, be only provided with a liner plate, so maintain and replace cost greatly reduces.
3. the inside of fixed guide of the present utility model is provided with one group of ball, when connecting rod moves in fixed guide, rubs little, and resistance is little, moves smooth and easy.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
In figure: 1, broken cavity, 2, stationary crushing plate, 3, hit tup, 4, drive motors; 5, flywheel; 6, bearing pin; 7, connecting rod; 8, fixed guide; 9, ball; 10, liner plate.
The specific embodiment:
As shown in Figure 1: the underground mine use jaw crusher of the present embodiment, comprise broken cavity 1, one side of described broken cavity the inside is installed stationary crushing plate 2, the opposite side of described broken cavity is provided with the strike tup 3 along stationary crushing plate movement in vertical direction, described strike tup connecting drive device.After the lump coal of large grain enters broken cavity, broken under the effect of hitting tup, carry again after being crushed to suitable granularity, avoid transporting equipment to produce the destruction of forms such as touching, hit, pound, to downhole safety, transportation brings convenience.
Described underground mine use jaw crusher, described drive unit comprises drive motors 4, described drive motors connects flywheel 5 by reductor, and the edge of described flywheel connects connecting rod 7 by bearing pin 6, and described connecting rod is connected with described strike tup through fixed guide 8.Thereby when drive motors rotates, drive reductor flywheel driven to rotate, the motion of flywheel drivening rod, due to the effect of fixed guide, makes connecting rod drive hit tup and moves reciprocatingly, and to entering the material of broken cavity, hits.
Described underground mine use jaw crusher, the inside of described fixed guide is provided with one group of ball 9.Ball be arranged so that connecting rod moves in fixed guide time frictional resistance little, move smooth and easy.
Described underground mine use jaw crusher, is provided with liner plate 10 on described stationary crushing plate.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-described embodiment, also comprises by above technical characterictic and is equal to arbitrarily the technical scheme that replacement forms.Unaccomplished matter of the present utility model, belongs to those skilled in the art's common practise.
