Description

ten

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

The purpose of the invention is to increase the compactness and efficiency of the crusher.

FIG. 1 frontally shows the structural scheme of the proposed crusher; in fig. 2 - the same, with local cuts, a plan view.

The crushed cheek 1, made in the form of a massive body, and the crushed cheek 2 are pivotally connected by means of an axis 3 in the form, for example, of a torsion.

The cheek 2 by means of bearings 4 carries an exciter with unbalances 5 at the ends of its shaft. Cheek 1 is driven by the engine 6 vibration exciter with 7 shaft bearings

the centers of unbalance masses are combined into a common plane 10, the trace of which in FIG. 2 is indicated by the axial line. The crusher can be supported by the cheek 1 as a body on the base by means of gaskets 11.

In rational versions, cheek 1 is much more massive than cheek 2, the static unbalance moments of the pathogens are the same, and the axis of swing of the cheek 2 and the axis of rotation of unbalances are in the same vertical plane.

During the operation of the crusher, the raw materials 15 are crushed in the chamber between the crushing cheeks. In a pair of conjugated unbalance unbalance 8, developing a centrifugal force imparted to cheek 1, at the same time serves as a lead for unbalance 5, imparting to it rotation. Due to the latter, oscillations of the cheek 2 are generated as a tick on axis 3.

With the choice of the ratio of the masses of the cheeks, the mobility of the cheek 1 as a cor20

And debapansam 8 on them. The shafts excite 25 ”whiskers are insignificant, i.e. he executors are coaxial, and the unbalance of one takes the function of the anvil. This helps to increase the efficiency of the shock system. Direct coupling of the debalance eliminates the need for 30-socket sleeves and makes the compactness of the component set antiphase with respect to the other.

Conjugated unbalances 5 and 8 are interconnected by radial faces 9, with the plane of rotation.

Claims (2)

1. JAW VIBRATION CRUSHER, containing two crushing cheeks with vibration exciters, the conjugate sector unbalances of which are antiphase mounted on coaxial shafts, characterized in that, in order to increase compactness and efficiency due to the leash connection of the unbalances between themselves, the conjugate unbalances are introduced for interlocking faces with the combination of the planes of rotation of the centers of unbalanced masses. 2. The crusher according to claim 1, with respect to the fact that one of the cheeks is hinged to the other, about which the hinge axis is located in a vertical plane passing through the axis of rotation of the unbalances.
