Receiving net structure of thresher

Abstract

PURPOSE: To increase the effective sieving area and improve the filtration efficiency by using a pair of unit nets to be placed adjacent to each other in circumferential direction and mutually intruding the opposite circumferential frame parts of the nets into the opposite frame part in the circumferential direction of the threshing drum. CONSTITUTION: The receiving net 2 has a dividable structure consisting of a pair of unit nets 5,5 integrally molded with a plastic material and connected in the circumferential direction of a threshing drum 1. The circumferential frame parts 6,6 of the unit nets 5,5 placed opposite to each other in the circumferential direction are intruded with each other into the opposite frame in the circumferential direction of the threshing drum 1 to form a fitting structure. The intrusion parts 7,7 of the frame parts 6,6 are attached to the supporting frame 9 of a threshing chamber 8 for attaching the receiving net. Since the opposite circumferential frame parts are intruded into the opposite member, the length of both circumferential frame parts in the circumferential direction of the threshing drum can be shortened compared with conventional net consisting of a simple butt arrangement of the circumferential frame parts.
