Description
Technical field
The utility model is mainly concerned with the sample making apparatus field, refers in particular to a kind of jaw crusher.
Background technology
Jaw crusher mainly is made up of support, body, fixed jaw (deciding jaw), sewing jaw (moving jaw), eccentric shaft, movable rod, blocking mechanism, feed hopper and receiving hopper etc.Shattering process is roughly following: behind the motor start-up, drive big flywheel and eccentric shaft rotation through bead apex, under eccentric shaft and the effect of moving jaw plate connecting rod, moving jaw plate is decided the reciprocating motion that jaw is done the cycle relatively.Material is by jaw bump and rubbing and fragmentation between two jaws, and the material after the fragmentation gets into receiving hopper from the jaw end opening, regulates jaw end opening (discharge gate) gap, i.e. the scalable marker size.
Traditional jaw crusher generally be position through regulating moving jaw regulating the spacing between two jaws, and then regulate the granularity of material.Common regulative mode all is to change moving jaw and decide the distance between the jaw through the angle of regulating thrust plate and connecting rod; But there is following problem in this structure: 1, moving jaw links to each other with power-transmitting part; When regulating the position of moving jaw; Often need adjust accordingly power-transmitting part, very loaded down with trivial details, debugging work is also very complicated; 2, regulate spacing between the jaw (gap) by the way after, all need constantly to sieve broken thing, and confirm recently through the percentage of judging oversize whether adjusting qualified with square hole screen.Otherwise just need to continue to regulate the size of opening, and do not accomplish the scale demonstration of jaw spacing and the zeroing compensation after the jaw wearing and tearing.
The utility model content
The technical problem that the utility model will solve just is: to the technical problem that prior art exists, the utility model provides a kind of simple and compact for structure, with low cost, operation is easier, the granularity degree of regulation is higher jaw crusher.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of jaw crusher; Comprise frame and be installed on the frame moving jaw assembly with decide the jaw assembly; Said decide the jaw assembly comprise decide jaw with decide the jaw fixed mount, said top of deciding the jaw fixed mount is articulated on the frame, said bottom of deciding the jaw fixed mount links to each other with a granularity adjusting part; Said granularity adjusting part comprises adjusting nut, screw mandrel and screw mandrel jacking block, and said adjusting nut is installed on the screw mandrel and can only rotates, and said screw mandrel holds out against the bottom of jaw fixed mount through the screw mandrel jacking block.
Further improvement as the utility model:
Said screw mandrel jacking block and decide to be provided with tension spring between the jaw fixed mount.
Said bottom of deciding the jaw fixed mount is provided with pointer, and the scale marker that is provided with on said pointer and the frame cooperates.
Said adjusting nut links to each other with an adjusting handle.
Said screw mandrel is provided with spring guide, is arranged with the compression spring on the screw mandrel between said spring guide and the adjusting nut.
Compared with prior art, the advantage of the utility model is: the utility model jaw crusher, and the mode that adopts accurately driving to decide the jaw motion is adjusted granularity; Operation is very easy, but also can cooperate with pointer, operates more directly perceived; Controllability is better, and degree of regulation is higher.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Marginal data:
1, moving jaw assembly; 2, decide the jaw assembly; 21, decide jaw; 22, decide the jaw fixed mount; 3, frame; 4, adjusting nut; 5, screw mandrel; 6, screw mandrel jacking block; 7, pointer; 8, scale marker; 9, adjusting handle; 10, spring guide; 11, compression spring; 12, tension spring.
The specific embodiment
Below will combine Figure of description and specific embodiment that the utility model is explained further details.
As shown in Figure 1; The jaw crusher of the utility model comprises frame 3 and is installed in moving jaw assembly 1 on the frame 3, decides jaw assembly 2, power-transmitting part or the like; Deciding jaw assembly 2 comprises and decides jaw 21 and decide jaw fixed mount 22; The top of deciding jaw fixed mount 22 is articulated on the frame 3, and the bottom of deciding jaw fixed mount 22 links to each other with a granularity adjusting part; The granularity adjusting part comprises adjusting nut 4, screw mandrel 5 and screw mandrel jacking block 6, and adjusting nut 4 is installed on the screw mandrel 5 and through locating part its axially-movable is limited it can only be rotated, and screw mandrel 5 holds out against the bottom of jaw fixed mount 22 through screw mandrel jacking block 6.Rotation adjusting nut 4, screw mandrel 5 are toward the direction motion of deciding jaw fixed mount 22, and the bottom motion that screw mandrel jacking block 6 is pushing away jaw fixed mount 22 realizes the openings get smaller between two jaws; On the contrary, during opposite spin adjusting nut 4, screw mandrel 5 is toward moving away from the direction of deciding jaw fixed mount 22, and jaw fixed mount 22 toward the direction motion away from moving jaw assembly 1, realizes that the opening change between two jaws is big under the effect of deadweight.
In the present embodiment, screw mandrel jacking block 6 and decide to be provided with between the jaw fixed mount 22 tension spring 12, this tension spring 12 can play to be eliminated screw mandrel jacking block 6 and decides the effect in gap between the jaw fixed mount 22, can also have certain pretightning force.
In the present embodiment, the bottom of deciding jaw fixed mount 22 is provided with pointer 7, and the scale marker 8 that is provided with on pointer 7 and the frame 3 cooperates.When deciding jaw fixed mount 22 motion, pointer 7 can be along with one of which plays motion, and scale marker 8 is that the radius of turn according to pointer 7 configures, and the numerical value change on this scale marker 8 is the mobile and horizontal distance of deciding jaw 21.So just make that whole adjustment process is directly perceived more, controllability is good, degree of regulation is high.If after the jaw noticeable wear, discharging-material size will become greatly, and will be accurate in order to make scale; It is zero regulating the distance decide between jaw 21 and the moving jaw plate, adjusts scale marker 8 residing positions simultaneously, make pointer 7 again the aligned at zero scale get final product; Thereby realize the purpose of zeroing, with the compensate for wear value.
In the present embodiment, adjusting nut 4 links to each other with an adjusting handle 9.Screw mandrel 5 is provided with spring guide 10, is arranged with compression spring 11 on the screw mandrel 5 between spring guide 10 and the adjusting nut 4.When the motion of using 9 pairs of screw mandrels 5 of adjusting handle is adjusted, utilize compression spring 11 can play certain damping, help self-locking.One side of adjusting handle 9 also is provided with holding screw, after having regulated, can also lock once more.
Below only be the preferred implementation of the utility model, the protection domain of the utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to the protection domain of the utility model.Should be pointed out that for those skilled in the art,, should be regarded as the protection domain of the utility model in the some improvement and the retouching that do not break away under the utility model principle prerequisite.
