A high-efficiency jaw crusher with large bite force

Abstract

The invention discloses a high-efficiency jaw crusher with large bite force, wherein a drive shaft, a crushing pair, a moving jaw and a toggle plate are arranged on a rack; the crushing pair comprises a pair of tooth plates standing opposite each other so as to form a crushing cavity; one tooth plate is fixedly connected on the rack and the other tooth plate is fixedly connected on the moving jaw; the upper end of the moving jaw is pivoted on the drive shaft and the lower end of the moving jaw is pivoted on the toggle plate; a driving wheel is connected on the drive shaft; and the tooth plates are flat plates with reticular mesh structures. According to the invention, a traditional way of setting tooth form on the basis of a conventional technical tooth plate is broke through; a toothless tooth plate is provided; the tooth form design is replaced by a honeycomb reticular mesh design to ensure that the crushing functions of split, breaking and extrusion are strengthened; the most remarkable effect is that a crushing mechanism mainly based on extrusion and squash in the prior art is changed into comprehensive application mainly based on filing and shear and supplementarily based on the split, the breaking and the extrusion; and then, larger crushing bit force are provided and the crushing performance is greatly improved.

Description

technical field [0001] The invention relates to the technical field of jaw crushers, in particular to a high-efficiency jaw crusher with large bite force. Background technique [0002] One of the main mechanisms in the jaw crusher equipment is the crushing chamber, which consists of two tooth plates (also called jaw plates or tooth plates). Jaw crushers in the prior art generally do not use solid flat plates, but toothed tooth plates for two reasons: one is that the contact surface between the toothed tooth plates and the material is small, and the crushing pressure is strong; the other is to use the tooth shape To achieve "splitting, crushing, crushing" and other crushing work methods (when the tooth crest squeezes the material: the way that the material will be split by the pressure along the tip is called splitting; the material is subjected to bending stress The way of being broken is called crushing; the way of material being crushed due to the compressive stress on th...

AI Technical Summary

Problems solved by technology

Although the self-repairing tooth shape can eliminate the sub-plate broken state to a certain extent, due to the existence of the tooth shape, the biting force of the relative cooperation between the tooth valley and the tooth peak is still insufficient (due to the existence of through holes at the tooth valley, there is a biting force , not at the crest)
