PROBLEM TO BE SOLVED: To provide a receiving net made of a metal plate that is superior in strength and can be manufactured relatively inexpensively, and that prevents objects such as dust from adhering to the back of the net when processing moist material, and prevents clogging due to the growth of dust, etc. adhered thereto.SOLUTION: The threshing device 1 includes: a threshing cylinder 4 rotatably disposed in a threshing chamber 2, and for threshing grains from grain culms fed into the threshing chamber 2 and a receiving net 6 disposed along a lower part of the threshing cylinder 4, and for leaking the grains threshed in the threshing chamber 2 to a lower side of the threshing chamber 2. The receiving net 6 is formed of a metal plate having a plurality of leaking holes 6a for leaking the grains. Only the back surface of the net that does not face an outer periphery of the threshing cylinder 4 is applied with water repellent treatment 6b.COPYRIGHT: (C)2013,JPO&INPIT【課題】強度的に優れ、比較的安価に製造可能な金属板製の受網でありながら、湿材の処理に際し、裏面側に対する屑類の付着を抑制すると共に、付着した屑類の成長による目詰まりを防止する。【解決手段】扱室2内に回転自在に配置され、扱室2内に供給される茎稈から穀粒を脱穀する扱胴4と、該扱胴4の下側に沿って配置され、扱室2内で脱穀された穀粒を扱室2の下方に漏下させる受網6とを備える脱穀装置1において、受網6は、穀粒を漏下させる多数の漏下孔6aが形成された金属製の板材からなり、扱胴4の外周と対向しない裏面側のみ撥水処理6bが施される。【選択図】図5
