CLEANER OF THE PLANE SCREENS Russian patent published in 2007 - IPC B07B1/50 

FIELD: agricultural machinery industry; production of the grain-cleaning machines.

SUBSTANCE: the invention is pertaining to the agricultural machinery industry, in particular to production of the grain-cleaning machines for cleaning and grading of seeds of crops. The cleaner of the plane screens includes the frame located in the screen boot between the screen and the supporting grate divided by the slats into the square or rectangular cells with the located in them cleaning components, and the installed with the possibility of vibration together with the screen boot and the free reciprocating motion with respect to the screen boot. The stop components are made out of the elastic material. The stop components are consolidated on the butt walls of the screen boot, the supporting grate is made out of the bars and the cells of the frame are formed by the longitudinal and transversal slats. At that the longitudinal slats are made with the height exceeding the height of the transversal slats and rest on the bars of the supporting grate with the possibility of the free relocation of the frame concerning the screen boot from one supporting component to anther by the value of no less than the half of the diameter of the cleaning components made in the form of the hollow flexible cylinders or beads. At that the diagonal size of the cylinders or the diameter of the beads is made smaller, than the gap of the under-screen space. The technical result of the invention is the increased efficiency of the screens cleaning and simplification of the screen cleaner design.

EFFECT: the invention ensures the increased efficiency of the screens cleaning and simplification of the screen cleaner design.
