PROBLEM TO BE SOLVED: To provide a thresher allowing easy setting of an initial rotating position of each of the dust feeding guides, and individual rotating of each of a plurality of dust feeding guides according to a load from a material to be treated.SOLUTION: The thresher includes: the plurality of freely rotatable dust feeding guides 27 installed for guiding the material which is to be treated and flows in the interior of a threshing chamber 13 on the upper side of the threshing chamber 13 elastic members 29 provided for elastically urging each of the dust feeding guides 27 into the initial rotating position and a setting mechanism 31 installed for setting the initial rotating position of each of the dust feeding guides 27. In the thresher, the setting mechanism 31 is provided with a movable member 28 which can be moved in operative connection with a change in setting of the initial rotating position of each of the dust feeding guides 27, and contact parts 39a, 57, and 59 are installed for contacting the side of the dust feeding guides 27, and regulating the rotation of the dust feeding guides 27 to the side urged with the elastic members 29 individually for each of the dust feeding guides 27 in the movable member 28. Thereby, the initial rotating position of each of the dust feeding guides 27 is defined by contact of the dust feeding guides 27 with the contact parts 39a, 57, and 59.COPYRIGHT: (C)2012,JPO&INPIT【課題】送塵ガイドの初期回動位置を容易に設定することができるとともに、各複数の送塵ガイドが、それぞれが処理物からの負荷に応じて個々に回動する脱穀装置を提供することを課題としている。【解決手段】扱室13内を流動する処理物を案内する送塵ガイド27を、扱室13の上方側に回動自在に複数備え、各送塵ガイド27を初期回動位置に弾性的に付勢する弾性部材29と、送塵ガイド27の初期回動位置を設定する設定機構31とを設けた脱穀装置において、設定機構31が、送塵ガイド27の初期回動位置の設定変更に連動して可動する可動部材28を備え、送塵ガイド27側と接当して弾性部材29が付勢する側への該送塵ガイド27の回動を規制する接当部39a,57,59を、送塵ガイド27毎に各別に可動部材28に設け、送塵ガイド27と接当部39a,57,59との接当によって、該送塵ガイド27の初期回動位置が定められる【選択図】図3
