Description

The invention relates to the mining industry and is intended for the sorting of the HOROLM and the preparation. its transportation in mining conditions. .

The purpose of the invention is the expansion of technological capabilities by providing a change in the direction of product dropping in cramped, mining conditions.

FIG. 1 shows a device for sorting rock mass, general view; in fig. 2 is a view A of FIG. one; in fig. 3 - the device, view from the drive side.

The device for sorting the rock mass consists of the grate 1, on which the drive frame 2 is installed on the opposite side of the load. The drive of the device consists of a power cylinder 3, a lever 4, a connecting link 5 and a pusher 6. The lever 4 is pivotally connected to the drive frame 2, the middle part to the cylinder 3, and the lower end to the connecting link 5, which is pivotally connected pusher 6. The latter on the opposite side is rigidly connected to the comb 7, which is pivotally mounted in the slider 8, which is supported on the guides 9. The switching unit is made in the form of two stops mounted on the slider. Each stop has two positions, in one of which it contacts with the pusher, restricting its rotation, and in, the other does not limit.

A device for sorting rock mass works as follows.

After mounting the device, the stop 10, located on the side into which the shear product is to be dropped, is inserted into the slider hole

8, and the opposite stop is withdrawn. When the lever 4 moves under the action of the cylinder 3, the lower end of the lever 4 pushes the connecting link 5, the pusher 6, which abuts against the inserted stop 10, pushes the slider 8 with the ridge 7, which drop the sheath product. During the movement of the rod 4 in the opposite direction, the pusher 6 rotates and thereby rotates

comb 7 before you remove her teeth under the grate 1, since there are no stops for Yu in the slider 8 on this side. With this, dropping the oversize product does not occur. Control

hydraulic cylinder 3 is performed by the automation system of the whole complex of machines. Then the whole cycle is repeated.

Introduction to the technological chain of the proposed device for sorting rock mass eliminates the cost of manual sampling of oversized pieces and eliminates the loss of productivity of the equipment complex due to the shutdown of the pneumatic conveying installation.

The possibility of placing the device in the place of removal from the loading body of the combine to the drift conveyor .. allows it to be used without increasing the cross sections of the mine workings carried out by the combine and without building additional niches. The presence of a switching device allows you to quickly change the direction of dropping when the position of the bottom is changed.
