Efficient fine polyurethane self-cleaning sieve plate

The utility model provides an efficient subdivision polyurethane self-cleaning sieve plate which comprises a polyurethane frame, a mounting groove is formed in the top of the polyurethane frame, a supporting framework is movably connected to an inner cavity of the mounting groove, and a bent steel wire is fixedly connected to the upper end of an inner cavity of the supporting framework. Five supporting plates are fixedly connected to the lower end of an inner cavity of the supporting framework. The polyurethane frame and the mounting groove are used for containing the supporting framework, the supporting framework is arranged, the effect of fixing the bent steel wires is achieved, the stability of the bent steel wires in the using process is improved, and the problem that in the actual using process, a large number of sheet-shaped long-strip materials mixed in screened materials are prone to being embedded into gaps of the screening plate, and the screening effect is affected is solved. And the problems that
