PROBLEM TO BE SOLVED: To provide a thresher 1 that enables replacement of a worn protrusion 58 and an as-needed increase or decrease in the number of the protrusions 58 by enabling removal of the protrusion 58 attached to a top surface of a perforated plate 54 constituting a receiving net 13.SOLUTION: A receiving net 13 is made of a perforated plate 54 in which a large number of leakage holes 53 are punched. Protrusions 58, which protrude toward a threshing cylinder 12 from the perforated plate 54 and which perform shedding processing by making broken ears and the like collide with one another, are detachably provided on the receiving net 13. Additionally, the protrusions 58 are attached to the back side of the perforated plate 54 by utilizing reinforcing plates 57a-57d.COPYRIGHT: (C)2015,JPO&INPIT【課題】受け網13を構成する多孔板54の上面に付設する突起58を取り外すことができるようにして、摩耗した突起58の交換や突起58の数を必要に応じて増減させることができる、脱穀装置1を提供する。【解決手段】受け網13を、多数の漏下孔53を打ち抜き加工した多孔板54で構成すると共に、多孔板54から扱胴12に向けて突出し、穂切れ等を衝突させて脱粒処理を行う突起58を、受け網13に着脱自在に設ける。また、突起58を補強板57a~57dを利用して多孔板54の裏面に取り付ける。【選択図】図3
