SIEVE ASSEMBLY FOR SEPARATING GRAINS FROM PLANT RESIDUAL MATERIAL

Abstract: a sieve assembly includes planar components including sieves, supported by rocking arms configured to actuate a fore-aft rocking movement to the components. at least one of the rocking arms is connected to one of the components by a conical connection having a first and second connection piece having matching conical surfaces. the conical connection can be secured and released from the side of the rocking arm. the first connection piece is rotatably mounted in an opening of the rocking arm, and a securing bolt passes through the opening and through the first connection piece, and is screwed into the second connection piece. the first connection piece has a threaded portion at the side of the rocking arm, enabling to insert a pin into the first connection piece, and screw an auxiliary bolt into the threaded portion after the removal of the securing bolt, to thereby force the conical surfaces apart.
