Description
Technical field
The utility model relates to a kind of industrial and mineral industry technology field, and more particularly, it relates to a kind of jaw crusher.
Background technology
Jaw crusher, is called for short Hubei Province and breaks, and is mainly used in the medium size of various ore and bulk materials broken, is widely used in the industries such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry.Jaw crusher is when broken material, its operation principle drives belt and belt pulley by motor, by eccentric shaft, jaw is moved up and down, when dynamic jaw rises, between bracket and dynamic jaw, angle becomes large, thus it is close to fixed jaw to promote moving jaw plate, meanwhile material is crushed or split broken, reaches broken object; When dynamic jaw is descending, between bracket and dynamic jaw, angle diminishes, and moving jaw plate, under the effect of pull bar, spring, leaves fixed jaw, and now broken material is discharged from crusher chamber end opening.Along with motor rotates and broken motor-driven jaw periodically crushes and drain material continuously, realize batch production.Jaw crusher is used mainly slightly to break raw material, for two-stage crushing is prepared.
Jaw crusher is suitable for the raw material of broken hard material or middle hardness, and be not suitable for the raw material of broken soft durometer, should be not more than 10% to the water content requirement of material, raw aqueous rate is too high, and on jaw, easy sizing, affects crushing efficiency.
Should be noted when using jaw crusher: before material enters disintegrating machine, in advance the powder in material should be sifted out, this has very large meaning to the utilization ratio of disintegrating machine ability, because these powders can clog the groove between jaw rib, the effective depth of rib is reduced, like that, material between jaw just to only rely on by means of pressure fragmentation, cause jaw pressure to increase, cause apparatus to damage, operating efficiency reduces and service life reduces.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of jaw crusher, and on jaw after sizing or the blocking of jaw groove, small size reduction only occurs crushing efficiency, extension device service life.
For achieving the above object, the utility model provides following technical scheme: a kind of jaw crusher, comprises
Dynamic jaw and fixed jaw, described fixed jaw is fixed with jaw, and described jaw is compressive plane towards the one side of dynamic jaw, and described compressive plane is fixed with projection, and described projection interval is arranged;
Housing, described fixed jaw is fixed on housing.
Preferably, described projection is truncated rectangular pyramids shape.
Preferably, the projection bottom surface of described truncated rectangular pyramids shape and the angle of side are 40 ° ~ 60 °.
Preferably, described projection is distributed in bottom fixed jaw to 2/3 At The Height.
Preferably, described compressive plane is obliquely installed.
Compared with prior art, the utility model has the advantage of: the projection on fixed jaw can increase ore extruding force, make large-scale ore more easily broken; Secondly, projection adds the height of jaw, and projection is not easily by material institute adhesion that hardness is lower, therefore, when material matter is soft or there is powder grain material, after the dead slot between the jaw of fixed jaw and dynamic jaw is clogged by material, projection still can give prominence to certain height, material is made to be easy to broken, the situation avoiding the material between dynamic jaw and fixed jaw to only rely on by means of pressure breaking occurs, and reduces disintegrating machine working resistance, extends its service life.

Detailed description of the invention
Referring to figs. 1 through Fig. 4, the utility model jaw crusher embodiment is described further.
Jaw crusher is when broken material, its operation principle drives belt and belt pulley by motor, by eccentric shaft, jaw 22 is moved up and down, when dynamic jaw 22 rises, between bracket and dynamic jaw 22, angle becomes large, thus it is close to fixed jaw 11 to promote dynamic jaw 22, meanwhile material is crushed or split broken, reaches broken object; When dynamic jaw 22 is descending, between bracket and dynamic jaw 22, angle diminishes, and dynamic jaw 22 is under the effect of pull bar, spring, and leave fixed jaw 11, now broken material is discharged from crusher chamber end opening.Along with motor rotates and broken motor-driven jaw 22 periodically crushes and drain material continuously, realize batch production.
As shown in Figures 1 to 4, a kind of jaw crusher, comprise dynamic jaw 2, fixed jaw 1 and housing, described fixed jaw 1 is fixed on housing, described fixed jaw 1 is fixed with jaw 11, and described jaw 11 is fixed with the projection 12 of truncated rectangular pyramids shape in the one side of dynamic jaw 2, and projection 12 interval is arranged, the angle of projection 12 bottom surface and side is 40 °, and projection 12 is highly 30mm.
Because projection 12 is little with the contact area of ore, therefore projection 12 is larger to the jaw 11 of the relative lath-shaped of surface pressure of contact ore, and therefore projection 12 can increase the extruding force of jaw 11 pairs of ores, makes ore more easily broken;
Projection 12 is truncated rectangular pyramids shape, and projection 12 top is less, and has 4 cusps, and the pressure produced ore is larger; Secondly, the powder produced during projection 12 pairs of ore grindings of truncated rectangular pyramids shape does not have delay effect, makes it more easily drop, fixed jaw 1 not easily clog by powder material.
The bottom surface of the projection 12 of truncated rectangular pyramids shape and side angle are 40 °, dynamic jaw 2 is about 70 ° with the angle of inclination of horizontal plane, when dynamic jaw 2 extrudes ore, dynamic jaw 2 enables ore contact the lower seamed edge of truncated rectangular pyramids, and ore is squeezed between two adjacent place's boss during extruding, dynamic jaw 2 upwarps in process and ore is broken on the downside of projection 12, increases the efficiency of ore grinding;
When the ore dampness pulverized is comparatively large and powder is more, after dead slot between jaw 11 is clogged completely, projection 12 height 30mm, jaw 11 is made to extend the height of 30mm, the situation avoiding the material between dynamic jaw 2 and fixed jaw 1 to only rely on by means of pressure breaking occurs, reduce disintegrating machine working resistance, extend jaw crusher service life.
Wherein, described projection 12 is distributed in bottom fixed jaw 1 to 2/3 At The Height.
Jaw crusher is when powder ore, groundwork position is to 2/3 height bottom fixed jaw 1, and without ore grinding in remaining 1/3 height and position, therefore projection 12 is arranged at this position, projection 12 can be made more accurately to be distributed in working position, save cost, improve disintegrating machine crush efficiency simultaneously.
Wherein, jaw 11 is compressive plane 11A towards the one side of dynamic jaw 2, and described compressive plane 11A is obliquely installed, compressive plane 11A opposed vertical face tilt 7 ° (tilting 7 ° towards dynamic jaw 2 above compressive plane 11A).
Fixed jaw 1 tilts after certain angle, and projection 12 first can be made to produce the inclination of respective angles, and the lower rib of projection 12 is just to dynamic jaw 2, and dynamic jaw 2 produces maximum extruding force when upwarping extruding, add the operating efficiency of jaw crusher;
Secondly, the fixed jaw 1 of inclination can prevent from the harder ore of quality from producing when fragmentation bursting apart, prevent stone from jumping out outside jaw crusher.Angle of inclination is larger, more can prevent stone from jumping out, but the opening of fixed jaw 1 lower end is larger, the particle produced after broken is larger, cause crushing effect to reduce, and when angle of inclination is greater than 10 °, the breaking capacity produced obviously reduce, therefore get 7 °, its angle of inclination, stone can be reduced and splash out while guarantee breaking capacity.
The above makes preferred embodiment of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
