Description

2, the Crusher according to claim 1, characterized in that it is provided with an autonomous multi-link drive of the striker head and an additional limiter for the movement of the lower cheek to the front. 3. The crusher of On 1, about 1 of t. so that the shock

The invention relates to the crushing of solid materials and rocks, namely, jaw crushers, and can be used in the mining, chemical and other industries of the industry, in the enrichment, processing and production of building and special materials.

The purpose of the invention is to increase the productivity of the crusher.

FIG. 1 and 2, cxeNfa of the proposed crusher is shown in two extreme positions; FIG. 3-6 - crusher options

The proposed crusher (Figures 1 and 2) includes a housing 1 with a fixed crushing cheek, a drive eccentric wap 2., a connecting rod link 3 of the mechanism for driving the upper movable cheek 4. connected to the lower movable cheek 5 by means of a hinge 6, an autonomous multi-link drive of the striker 7 with a mechanism 8 of the crank type and with a follower link in the form of a pin 9. Both the driven pinion link 3 of the drive of the upper cheek and the driven link (lever 9) of the drive of the striker 7 are jointly articulated with the hinge 6,

The lever 9 is elastically connected to the cheek 5 with the help of a pull-out unit 10. The crusher is provided with controllable buffer stops 11 and 12 of the cheek 5, respectively, back and forth. The stops can be pivotally connected to the power cylinders 13 and 14 and to the brackets 15 at the end of the cheek 5.

In the proposed crusher Shat: 7nnoy link 3, can be made in the form of three-arm lever (Fig. 3 and 4),

moreover, the striker 7 is fixed on its lower shoulder. According to FIG. The striker head 7 5 of the cheek 5 is made inside a bracket rigidly connected to the cheek 4, whereas the part opposite to the bracket can be made in the form of a stroke limiter 5 forward. The pin 7 can be attached to the upper cheek 4 (FIG. 6).

In the process of operation, the crushers loaded material from above as a result of the swings of the movable cheeks 4 and 5 are melted sequentially in the upper and lower chambers.

. The cheek 4 is driven by the shaft 2 through the link 3 A self-contained drive (figs, 1 and 2) with mechanism 8 and 9 due to strikes by the striker 7 causes the cheek 5 to oscillate with a higher, higher frequency. In the position of FIG. 1, the lower part of the cheek 5 is paused in a pause on the rear stopper 12, providing a delayed phase of unloading the product through the exit slit .. Then the striker 7 sharply pushes the cheek 5 forward S to the phase of accelerated crushing of the material. Upon completion of the forward stroke, the cheek 5 can continue to move forward by inertia, depending on the characteristics of the crush resistance of the rock. The limit for moving the cheek 5 forward is set by the stopper 11 (FIG. 2). Then the cheek 5 starts to retract back through the spring 10. The position of the stops 11 and 12 is remotely controlled automatically by means of cylinders 13 and 14 depending on the material properties and technological requirements and tasks.

When performing crushers according to FIG. 3 and 4 of the oscillation frequency of the cheeks 4 and 5 are the same. In the crusher (Fig. 6), lightweight start-up modes can be carried out under the obstruction, for which the cylinder rod pushes a maximum.

The operative control of the operating parameters of the junction of the cheek in the mode of the optimal law of its movement makes it possible to increase the productivity of the crusher 5 according to the output required; product.
