DEVICE FOR SCREEN CLEARANCE Russian patent published in 2008 - IPC B07B1/54 

FIELD: agriculture.

SUBSTANCE: device for mesh clearance includes plate holder section with screen fixed in it, reflective grid and bafflers gimbaled in undergrid space, separating the later on cells with clearing elements. Baffles are gimbaled in the upper part of undergrid space and made as shuttle-type rod-shaped baffles with lower and upper rods with supports located on them. Supports restrict rod-shaped baffles turn while swaying along with screen unit by means of gravity action, inertia and impact force, with ability of space maintenance between screen and upper rod of baffler, as well as between reflective grid and lower baffler rod in marginal positions less than 2/3 of sphere diameter or wedge height of clearing elements.

EFFECT: quality improvement of screen clearing and reliability of clearing elements work.
