Description

扱胴handle
　本発明は、扱胴に関する。 The present invention relates to a handling cylinder.
　特許文献１に示されるように、扱胴には、収穫された作物の全体が投入される扱室に扱室の前後方向に沿う姿勢で回転可能に設けられる扱胴支軸（回転支軸）と、扱胴支軸の前部に支持され、投入された作物を扱室の後方に向けて掻き込む掻込み部と、扱胴支軸のうちの掻込み部よりも後側の部分に支持され、掻込み部によって掻き込まれた作物を扱き処理する扱き処理部と、が備えられたものがある。また、この種の扱胴には、掻込み部に、基台部と、基台部の外周部に設けられた螺旋羽根と、が備えられ、扱き処理部に、扱胴支軸に沿った状態、かつ、扱き処理部の周方向に間隔を空けた状態で扱胴支軸に支持された複数の棒状の扱歯支持部材と、複数の扱歯支持部材それぞれにおいて、扱歯支持部材から扱き処理部の径方向外側に向けて突出する状態、かつ、扱胴支軸に沿った方向に間隔を空けた状態で扱歯支持部材に支持された複数の棒状の扱歯と、が備えられたものがある。 As shown in Patent Document 1, a baling drum support shaft (rotational shaft) is rotatably provided in a baling chamber into which the whole harvested crops are put, in a posture along the front-rear direction of the baling chamber. a raking portion supported by the front portion of the sling drum support shaft and raking the thrown crop toward the rear of the threshing chamber; and a shaving section for shaving the crops that have been raked by the raking section. Further, in this type of squeezing cylinder, the scraping portion is provided with a base portion and a spiral blade provided on the outer peripheral portion of the base portion. and a plurality of rod-shaped bristle tooth support members supported by the shaving drum support shaft in a state spaced apart in the circumferential direction of the shaving portion, and each of the plurality of bristle tooth support members. a plurality of rod-shaped cusps supported by the cusp supporting member in a state of protruding radially outwardly of the processing portion and spaced apart in a direction along the threshing cylinder support shaft. there is something

　上記した扱胴にあっては、掻込み部よりも後側において複数の扱歯支持部材が扱き処理部の周方向に間隔を空けて並んでいるので、掻込み部によって扱き処理部の前端部に掻き込まれた作物が扱歯支持部材どうしの間の隙間に入り込んでしまうと、扱き処理部による脱穀処理物である作物の受け継ぎがうまくいかず、扱き処理部における脱穀処理物の流れが悪くなる。 In the above-described shaving cylinder, since a plurality of tooth servicing support members are arranged at intervals in the circumferential direction of the shaving portion on the rear side of the scraping portion, the front end portion of the shaving portion is moved by the scraping portion. If the crops that have been raked into the threshing tooth support members enter the gaps between the threshing support members, the threshing material will not be transferred to the threshing part, and the flow of the threshed material in the threshing part will be poor. Become.
　本発明は、掻込み部によって扱き処理部に掻き込まれた作物を扱き処理部にスムーズに受け継がせることができる扱胴を提供する。 The present invention provides a squeezing cylinder that can smoothly transfer the crops that have been scrambled into the scouring processing unit by the scouring unit.
