2. roll over broken function: (material is on the side band metal fin at regular intervals, and by the fin of the staggered opposite side of face-off it is pushed, and material will produce flexural deformation, when its bending stress reaches transverse modulus of rupture, then by the fragmentation that fractures).In broken wall running, for size near the material of spiral bar bar size when broken, performance be the broken function of folding.
3. squeeze broken function: when material size critical in a side tooth plate the tooth bar spacing or during the aperture, squeeze broken (as squeezing toothpaste out of a tube) and will produce when being subjected to the offside extruding, be extruded after sub-fraction can be stripped from extruded material edge, Here it is squeeze broken.The less material of most of size can be by squeezing broken mode fragmentation in the crusher chamber of the broken wall of helical form.
In a word, the broken function of the broken wall of helical form is effective more than the broken wall of the solid tabula rasa of prior art.
Core technology of the present utility model is: by the helical form rib design to broken wall, substitute the tabular design of solid light of prior art, changed the prior art Cracking Mechanism to squeeze broken and crushing, become the integrated uses of multiple crumbling method such as " split broken, folding is broken, it is broken to frustrate, shred ", greatly improved the crushing efficiency of circular cone machine thus.
As preferably, on the broken wall in the mantle outside and bore surely and be provided with a spiral rib on the inboard broken wall, the rib hand of spiral on the broken wall in the mantle outside is opposite with the rib hand of spiral on boring inboard broken wall surely.
The utility model has scientifically used helical structure to have orientation to send the characteristic of power (when being seen as clockwise direction from top to bottom as the mantle direction of rotation, its hand of spiral is left-handed, otherwise fixed awl is then), thus make the circular cone facility that a kind of discharges material function in broken motion process be arranged.
As preferably, on the broken wall in the described mantle outside and bore the rib that is equipped with the double helix shape of arranged crosswise on the inboard broken wall surely.The grid district that the rib arranged crosswise of described double helix shape forms is a diamond-shaped meshes.
Broken wall surface has cancellated setting, increase from the principle wall roughness, frictional force increases, in fact it frustrate cutter and scissors just as a secondary well combination, have fully and frustrate, break broken function, and then make whole broken pair have big snap-in force function, thereby promoted the whole breaking capacity of jaw crusher effectively.
In the broken wall manufacture process, carry out the quenching heat treatment operation, promptly to red-hot broken wall immersion water, cool off fast, to reach the purpose of quench hardening heating.The utility model is provided with thickly dotted reticulated cell group with broken wall, increases the contact area of quench broken wall and water greatly, greatly helps the quenching degree in the quenching technical, thereby has strengthened hardness, wearability and the service life of broken wall.
