Description

"

The invention relates to the crushing and grinding of solid materials, namely, jaw crushers of vibration action, and can be used in the enrichment, processing and production of building and special materials, in the chemical, electrical, metallurgical and other industries.

The purpose of the invention is to increase the compactness of the crusher,

Figure 1 shows the structural design of the proposed crusher, frontally; figure 2 is the same, top view.

The crusher body 1 between the sidewalls 2 is mounted using bearings 3 oscillating cheeks 4 with unbalanced vibration excitators 5. Elastic elements in the form of torsions 6 are each made of two halves (figure 2), which are clamped apart by internal ends in the slots of the corresponding cheeks cheeks PIGIiIMOB

7, and the 1. Outer ends - in the slots of the levers 8. The latter are made

in the form of slotted elastic bück (Fig. 1, bending in a plane) with slots 9 forming elastic plates 10. The sides 2 with the supports 11 5 are connected by means of elastic elements 12 to the trunnions 13 of the ends of the torsions and are supported by soft springs 14 base 15.

 О During the operation of the crusher, the top loading material is crushed between the anti-phase oscillating cheeks 4 and, as it is crushed, is poured down from the bottom to the unloading.

5 The cheeks are swung on torsions, performing the functions of both the swing axes and the torsional elastic elements. At the same time, the levers 8 are elastically deformed, like bending beams, a section with torsions, the function of elastic oscillations.

As a result, it is possible to reduce the length of the torsions with the required overall rigidity and moderate tension in the material of both the levers 8 and torsions 6, which increases the compactness of the crusher.
