しかし、従来の搬送終端側から駆動する排藁搬送装置の穂先側搬送装置は、搬送位置によって姿勢が変化する排藁の穂先部を効率的に搬送することができず、搬送中に排藁が排藁搬送装置に詰まる恐れがある。
また、排藁搬送装置の穂先側搬送装置の全長は長く、脱穀装置の後部に該排藁搬送装置を配置する大きな空間が必要となり、扱室の空間が制限され、扱室に長尺な扱胴を設けることが困難となり脱穀能率が低下する恐れがある。 However, the tip side transport device of the conventional waste transport device driven from the transport end side cannot efficiently transport the head portion of the waste whose posture changes depending on the transport position. There is a risk of clogging the waste transport device.
In addition, the total length of the tip-side transfer device of the waste transporting device is long, requiring a large space for arranging the waste transporting device at the rear of the threshing device, limiting the space of the handling room, and handling the long handling space in the handling room. It may be difficult to provide a trunk and the threshing efficiency may be reduced.
