Description

I

The invention can be applied in the mining, coal, non-metallic industries and other branches of the national economy.

Chain screens are known that contain chains, a frame, driving and trailing sprockets, a drive and a tension device.

The purpose of the invention is to increase the efficiency and reliability of operation, as well as the ability to give the chain movement the desired direction.

This is achieved by the fact that each chain is placed in a rigid case and provided with shoes pivotally connected to it, with guide rails for the shoes in the upper part of the case, and guide rails for the chain in the upper part of the case.

FIG. 1 schematically depicts the described screen, a general view; in fig. 2 is a cross section along LL in FIG. one.

The chain screen contains chains (1) placed in a rigid casing (2), bashmaks (3), clamped pivotally in chains, upper guides 4, along which the bows move, and lower guides 5, along which the chain moves. The screen is driven by the electric motor 6 through the gearbox 7. The drive shafts 8 are connected through the couplings 9. There are a tensioning device 10 and a drive sprocket //.

Blatodar that the values of the rumble are placed in a rigid case and move along the guides, you can set the desired movement path of the penalties. The movements in the upper guides of the base box are the supporting elements and. hang on load, with a chain of shoes on the shoes.

When moving along the lower guides, the bashmaks freely hang on the chain. The hinge connection of the shoes with a chain provides the possibility of turning around the longitudinal axis of the value, therefore, when they hit the tower, stones are deflected and thus do not prevent the material from passing between two parallel chains. As a result, the clogging of the groin-shaped cracks is eliminated.

Chain ratchet containing chains, frame, driving and driven sprockets, drive and tension construction, characterized in that, in order to increase the efficiency and reliability of work, as well as the possibility of imparting chains to the route. Each stump is placed in a rigid case and is equipped with shoes connected to it, and in the upper part of the Cornus, the guides for the shoes are mounted, and in the lower part, 1-direction for ncni.
