Description

Efficient single toggle jaw crusher

Technical field

The utility model belongs to the crushing mechanism technical field, especially belongs to efficient single toggle jaw crusher.

Background technology

The shortcoming that traditional jaw crusher ubiquity blanking is slow, yield poorly, fracture failure easily takes place for eccentric shaft, moving gnathosoma, bracket in the main member, at these shortcomings, the utility model has designed efficient single toggle jaw crusher, compare concrete crushing efficiency height through practical proof with traditional disintegrating machine of the same type, the parts long service life, advantages such as specific energy consumption is low, user's consistent favorable comment.

Summary of the invention

The purpose of this utility model is low at traditional disintegrating machine production efficiency, the flimsy defective design of main parts size, a kind of efficient single toggle jaw crusher is provided, its main structural components comprises: the main frame wheel, eccentric shaft, moving gnathosoma, frame, flywheel, sewing jaw, fixed jaw, bracket, the bracket seat, regulate screw mandrel, the spring pull bar, formations such as spring, the main frame wheel is connected with eccentric shaft one end by flat key gives eccentric shaft with transmission of power, the other end of eccentric shaft is connected with flywheel, eccentric shaft is assembled into one by one group of bearing and moving gnathosoma, be connected with frame by another group bearing simultaneously, moving gnathosoma rear lower is supported on the bracket seat by bracket.Eccentric shaft, moving gnathosoma, bracket, bracket seat and crank and rocker mechanism of the common composition of frame.

Fixed jaw is fixed on the frame front end, sewing jaw is fixed on the moving gnathosoma and constitutes a jaw that is similar to animal with fixed jaw, do open and close movement by the moving gnathosoma of rotation drive of eccentric shaft and will treat broken material crushing, the driven gnathosoma bottom discharge of the crushed back of material.

Regulate screw mandrel be located at the bracket seat after bring in and regulate the discharge gate size, spring pull bar one end is fixed on the lower end of moving gnathosoma, the other end is fixed on the pedestal by spring, utilizes the strength of spring to make bracket and bracket seat closely connect and compose a reliable hinge-coupled.Bracket base rear end and adjusting screw(rod) are fixed on the frame.

Eccentric shaft structure: traditional similar disintegrating machine product eccentric shaft all adopts the 45# steel, and eccentric throw is made as 10-12mm.The design's eccentric shaft adopts the modified HB240-280 material of 40Cr, strengthened eccentric throw, eccentric throw is 13.5-17.8mm, can guarantee that the stressed strength degree that is no more than of eccentric shaft causes fracture, can guarantee fully that again the radial motion distance of sewing jaw meets the needs of material crushing, wherein the optimum value of eccentric throw is made as 15mm.Adopt this eccentric shaft scheme both to increase the crushing efficiency of 5%-18%, increased the service life of eccentric shaft again.

Moving gnathosoma structure: because when feed gap dimension is identical, the length of moving gnathosoma will determine the angle of charging aperture fixed jaw and sewing jaw, this corner dimension plays an important role to effective crushing force, and when having only horizontal component when crushing force much larger than vertical stress component, crushing efficiency could improve.Therefore, this angle should be got 20 ° of-30 ° of angles, under the situation of overall structure and the permission of stressed part strength, dwindles the angle angle.The value of similar this angle of disintegrating machine of tradition is greater than 30 °, so the broken motor-driven gnathosoma of the design is than the long 10-20% of the motor-driven gnathosoma of traditional fragmentation of the same type, to guarantee the value requirement of this angle.

The bracket structure: the bracket of other similar disintegrating machine is a linear pattern, but jaw crusher often runs into the situation of instantaneous overload at work, and the design is designed to S shape with bracket, bracket deformation failure during with the assurance overload, thus protect other stressed part can not damage.

The bracket horizontal sextant angle: bracket is connected back bracket and horizontal line formation with the bracket seat angle is the bracket horizontal sextant angle, the horizontal movement of the moving gnathosoma of horizontal sextant angle decision of bracket is apart from size, horizontal movement is apart from the height of decision crushing efficiency and the effect of material fragmentation, should increase the horizontal movement distance as far as possible during actual the use, reduce the distance that moves both vertically, according to practice, it is 20 ° of-35 ° of angles that this angle is answered value, and optimum value is 30 °.Other this angle of similar disintegrating machine though bigger angle is favourable to fragmentation, is considered the strength degree value of stressed part less than 20 ° of angles, and this angle should not surpass 35 °, otherwise easily causes the damage of stressed part.

Adopt the beneficial effect of the technical program: improved crushing efficiency, prolonged the service life of parts, specific energy consumption is reduced, bracket has other stressed part of protection to avoid damaging function during overload.
