Further, described raised item 11 cross section is trapezoidal shape, and raised item 11 is greater than the width of raised item 11 near one end of main connecting plate 10 away from the width of one end of main connecting plate 10.
Further, described groove 21 cross section is trapezoidal shape, and raised item 11 sleeve is in groove 21.
Further, in 45 ° to 60 ° angles between the two side of described toothed projections bar 22.
Further, described impingement plate 20 is made up of cubic boron nitride material.
Further, elastomer block 40 is clamped with between the bottom surface of described secondary toothed projections bar 30 and the sidewall of toothed projections bar 23.
Further, the top of described toothed projections bar 23 has curved portions, and the top of secondary toothed projections bar 30 has curved portions.
Further, in 60 ° to 120 ° angles between the two side of described secondary toothed projections bar 30; Described spring 52 is butterfly spring.
Jaw crusher in mine, building materials, the department such as capital construction be mainly used as boulder crusher and intermediate crusher.Be divided into three kinds, large, medium and small type according to charging aperture width size, what charging aperture width was greater than 600MM is heavy-duty machines, and charging aperture width is medium-sized machine 300-600MM's, and what charging aperture width was less than 300MM is minicomputer.Jaw crusher structure is simple, easy to manufacture, reliable operation.The working portion of jaw crusher is two pieces of jaws, one is fixed jaw (determining jaw), vertically (or upper end slightly flare) is fixed on body antetheca, another is sewing jaw (dynamic jaw), inclined position, forms up big and down small crusher chamber (working chamber) with fixed jaw.Sewing jaw does periodic reciprocating motion facing to fixed jaw, time and separate, time and close.Time separately, material enters crusher chamber, and finished product draws off from bottom; Near time, the material be contained between two pieces of jaws is squeezed, bending and slabbing action and broken.Jaw crusher is different according to the swing mode of sewing jaw, can be divided into simple swing type jaw crusher (simple pendular jaw crusher).Toggle-type jaw crusher (single toggle jaw crusher) and comprehensive swing type jaw crusher three kinds.
And jaw crusher tooth plate is the vitals of jaw crusher.
In the present embodiment, main connecting plate 10 has raised item 11, the back side of impingement plate 20 has groove 21, and raised item 11 sleeve, in groove 21, adopts and connects with upper type, thus when facilitating impingement plate 20 to damage, directly impingement plate 20 is upwards shifted out from main connecting plate 10, without the need to main connecting plate 10 is therefrom unloaded during its maintenance maintenance, effective, convenient disassembly, improves the efficiency of maintenance maintenance greatly.
And the end face of raised item 11 is fixed with Elastic Block 50, the middle part of Elastic Block 50 has elongate recesses 51, multiple spring 52 sleeve is in elongate recesses 51, Elastic Block 50 and spring 52 are clamped between the end face of raised item 11 and the end face of groove 21, make, when impingement plate 20 collides with rubble, there is buffering effect, reduce and damage.
And the front of impingement plate 20 forms toothed projections face 22, toothed projections face 22 is evenly equipped with multiple toothed projections bar 23, the both sides of toothed projections bar 23 are fixed with secondary toothed projections bar 30, adopt the double action of toothed projections bar 23 and secondary toothed projections bar 30, by rubble fragmentation more at the bottom of plus side, crushing effect can be improved.
Because secondary toothed projections bar 30 is bolted to connection on toothed projections bar 23, like this when secondary toothed projections bar 30 damages, directly unloading secondary toothed projections bar 30 can change, thus less maintenance cost.
Meanwhile, the height of the secondary toothed projections bar 30 that the side on described toothed projections bar 23 is fixed with is higher than the height of the secondary toothed projections bar 30 of opposite side.Described raised item 11 cross section is trapezoidal shape, and raised item 11 is greater than the width of raised item 11 near one end of main connecting plate 10 away from the width of one end of main connecting plate 10.Described groove 21 cross section is trapezoidal shape, and raised item 11 sleeve is in groove 21.Adopt the structure of trapezoidal shape to connect, ensure that the effect of connection, meanwhile, also for convenience detach.
In 45 ° to 60 ° angles between the two side of described toothed projections bar 22.This angle makes the height of toothed projections bar 22 increase, and meanwhile, angle reduces and toothed projections bar 22 can be made more sharp-pointed, thus improves broken effect, makes fragmentation more at the bottom of plus side.
And described impingement plate 20 is made up of cubic boron nitride material.Cubic boron nitride is synthesized at high temperature under high pressure by hexagonal boron nitride and catalyst, is another the novel new high-tech product occurred after diamond comes out.It has very high hardness, heat endurance and chemical inertness, and the excellent properties such as good saturating infrared shape and wider energy gap, its hardness is only second to diamond, but heat endurance is far above diamond, and to Ferrious material, unit have larger chemical stability.The grinding performance of CBN is very excellent, can not only be competent at the processing of difficult grind material, boost productivity, and effectively can also improve the grinding quality of workpiece.Therefore greatly improve its crushing effect, substantially can not damage.
And be clamped with elastomer block 40 between the bottom surface of secondary toothed projections bar 30 and the sidewall of toothed projections bar 23.Elastomer block 40 mainly plays flexible effect, reduces damaged possibility when ensureing that secondary toothed projections bar 30 is pressed.
The top of described toothed projections bar 23 has curved portions.Damaged effect to toothed projections bar 23 when curved portions effectively can prevent rubble direct collision toothed projections bar 23, improves its service life.
In 60 ° to 120 ° angles between the two side of described secondary toothed projections bar 30.Secondary toothed projections bar 30 adopts 60 ° to 120 ° angles, increases its intensity, thus improves its service life.And, because secondary toothed projections bar 30 is fixed on the sidewall of toothed projections bar 23, thus make the secondary toothed projections bar 30 adopting this angle can better broken rubble.
Finally; above embodiment is only for illustration of the utility model technology; and the restriction not to the utility model technology; the those of ordinary skill of relevant technical field; when not departing from the spirit and scope of the utility model technology; can also make a variety of changes and modification, therefore all equivalent technical schemes also belong to the category of the utility model technology, and the scope of patent protection of the utility model technology should be defined by the claims.
