Abstract

PURPOSE:To provide a thresher so designed that the width of a lattice member as a receiving net of a thresher is set based on specific conditions, thereby making deviated wear on the filter surface of the receiving net resistant to be developed even by use for a long period. CONSTITUTION:Many rectangular openings are formed with many longitudinal lattice members 24... arranged along the rotating direction of a handling drum 2 and many transverse lattice members 25... arranged along the direction of the rotational shaft core P of said drum 2, thus constituting a receiving net N with the width of the members 24 D24 smaller than that of the members 25 D25; and said receiving net N is integrally formed using a resinous material of high wear resistance and high water repellency.
