Abstract
The utility model relates to a new jaw crusher which belongs to the technical field of the crushing machinery. The jaw crusher comprises a crusher body, a fixed jaw plate, a moving jaw plate, a moving jaw, an eccentric shaft, a knee plate, a tension mechanism of the moving jaw, a regulating mechanism for the space between two jaw plates, and a driving wheel, wherein, the fixed jaw plate and the moving jaw plate are relatively sloped, and the fixed jaw plate and the vertical direction form an included angle with 9 to 10 DEG; the back face of the moving jaw plate is provided with a convex block which is connected with a groove in the relevant position of the moving jaw, and the upper part of the moving jaw is provided with the eccentric shaft which is connected with the driving wheel; the wall face on the lower part of the moving jaw is provided with a bearing groove which is fundamentally vertically contacted with a knee plate, and the other end of the knee plate is contacted with the bearing groove on a supporting seat. The jaw crusher has the advantages of simple structure and long service life.
Description
The utility model relates to a kind of ore crusher, belongs to the crushing mechanism technical field.
Lump ore is carried out fragmentation be absolutely necessary in industries such as building materials, metallurgy, the ore reduction common apparatus is a jaw crusher.Existing jaw crusher mainly contains vertical fixing jaw, sewing jaw and drives the moving jaw of sewing jaw and eccentric shaft, the formations such as bracket that play supporting role, because fixed jaw vertically is provided with, sewing jaw needs to tilt for 24 ° with the fixed head angle, certainly will make eccentric shaft stressed bigger like this, except needs drive the eccentric shaft with driving wheel, also to increase the inertia of eccentric shaft with another flying wheel, make the complete machine structure complexity like this; In addition, the bracket that moving jaw below is play supporting role is to acutangulate with the sewing jaw direction to be obliquely installed, and like this, the fulcrum place is bigger to the force direction angle of sewing jaw to the active force and the eccentric shaft place of sewing jaw, it makes a concerted effort then little, and is also little to the active force of ore.In addition, the jaw tooth on two jaws is to be covered with the plate face substantially, and two plate lower end average headways are bigger, and the granularity of discharging ore is bigger, and is comparatively serious to the wearing and tearing of moving jaw lower end.
The purpose of this utility model is, overcomes the shortcoming of prior art, provides a kind of little efficient of wearing and tearing high new type jaw crusher simple in structure.
The utility model is the improvement project that proposes on existing jaw crusher, and housing construction, power transmissioning part divide except that specifying all same as the prior art; Its main feature is: fixed jaw and sewing jaw relative tilt are provided with, 22-25 ° at two plate holder angles, and fixed jaw and vertical direction angle are 9-10 °, are a wedge shape space between two plates; Sewing jaw up and down two sides is inclined-plane, 10 ° of left and right sides, and sewing jaw back side upper and lower respectively has the groove of relevant position on a projection and the moving jaw to be connected; Moving jaw top is eccentric shaft, and eccentric shaft only is connected with a driving wheel; Moving jaw below has a spill pressure tank to contact with bracket, and the bracket other end contacts with spill pressure tank on the supporting base, and bracket does not all fix with supporting base with moving jaw and is connected; Compared with prior art, the utility model bracket is the reverse caster setting, and promptly bracket is basically perpendicular to moving jaw wall, as shown in Figure 1; Like this, the bracket place to the force direction of sewing jaw and eccentric shaft place to sewing jaw force direction basically identical, thereby improved the extruding force of sewing jaw to ore; Bracket has the rubber backplate facility that prevents dust outward, and this point is same as the prior art.The same with prior art, link on the moving jaw wall and connect a spring tensioning mechanism, different is the top that this mechanism is located at bracket, can reduce wearing and tearing like this, can reduce the volume of complete machine again.
The guiding mechanism of being made up of bolt and regulating block at the bracket supporting base opposite side relative with bracket is to regulate the spacing of fixed jaw and sewing jaw lower end; After the push bolt, adding regulating block between supporting base and body wall can be with corresponding the turning down of two jaw lower end spacings, otherwise it is big that above-mentioned spacing is transferred.Along with the wearing and tearing of jaw, in order to guarantee to grind the granularity of ore, generally need above-mentioned spacing is turned down, there has been above-mentioned guiding mechanism just to make this operation very easy.
The length of above-mentioned sewing jaw is suitably increased, make it be longer than fixed jaw, and exceed charging aperture to avoid ore to the wearing and tearing of sewing jaw top with the fixed connecting piece of moving jaw, connector herein is hold-down bolt and compresses voussoir.
Fixed jaw and sewing jaw two ends interchangeable up and down use.Jaw tooth on the two jaw flour millings reduces near two the time gradually, and leaves one section no jaw flank of tooth near the distance edges of boards, to reduce the average headway of two jaw lower ends, the granularity of discharging ore is reduced.
The said fixing jaw was fixed with being connected with taper of body; Also fix between eccentric shaft supporting flap and the body with voussoir; When this fixed form can be avoided with nut fixedly in motion process loosening between each parts.
Ore enters disintegrating machine from material inlet, and as shown in Figure 2, after motor started, driving wheel drove eccentric shaft and rotates, and makes sewing jaw do the motion of crank rocking bar, is squeezed in the ore between fixed jaw and the sewing jaw, and broken ore is outside discharging opening discharge machine.
The utility model is described in further detail below in conjunction with description of drawings and embodiment.
Fig. 1 is the utility model internal structure cutaway view, wherein, and 1. body, 2. fixed jaw, 3. sewing jaw, 4. projection 5. moves jaw, 6. groove, 7. eccentric shaft, 8. pressure tank, 9. bracket, 10. supporting base, 11. dustproof backplates, 12. collude, 13. spring tensioning mechanisms, 14. bolt, 15. regulating blocks, 16. hold-down bolts, 17. compress voussoir, 18. taper, 19. jaw teeth, 20. supporting flaps, 21. tension pieces, 22. tightening wedge, 23. rolling bearings, 24. limit backplates, 25. discharging openings.
Fig. 2 is the utility model external structure schematic diagram, wherein, and 26. limit backplates, the same Fig. 1 of all the other labels.
Embodiment. structure such as Fig. 1 are shown in Figure 2; 24 ° of two jaw angles, 9 ° of fixed jaw and vertical direction angles, two jaw lower end spacings are adjustable in the 8-40mm scope.
The utility model has changed the direction that is provided with of fixed jaw and bracket, thereby has improved the ore force structure, and the jaw force-bearing situation is improved, and has reduced the use of a flying wheel, has simplified complete machine structure; Also prolonged the service life of two jaws and moving jaw in addition.
