(イ) 産業上の利用分野
本考案は扱室内で持ち回られる藁を切断する藁
切り鎌の取付装置に関する。[Detailed description of the invention] (a) Industrial application field The present invention relates to a mounting device for a straw cutting sickle for cutting straw that is carried around in a handling room.

号公報等により提案された。(b) Prior art As a straw cutting sickle attachment device in a conventional threshing machine,
A pair of straw-cutting sickles are joined together at a connecting part to form a U-shape in plan view, and the connecting part is screwed to a mounting frame with a bolt in a direction substantially perpendicular to the handling barrel axis. −49383 Publication, Utility Model Publication No. 56-51720
It was proposed in the Publication No.

切り鎌が扱胴の回転方向へ傾動し、藁切り性能が
低下する欠点があり、かつ構造が複雑になつてコ
スト高であつた。(c) Problems to be solved by the invention The above-mentioned method in which the connecting part of the straw-cutting sickle is screwed onto the mounting frame with a bolt that is approximately perpendicular to the axis of the handling barrel requires that only the center of the connecting part be attached to the mounting frame with one bolt. If a large amount of straw waste is generated in the handling chamber, such as when the grain culm is wet, the cutting resistance will cause the straw cutting sickle to tilt in the direction of rotation of the handling barrel, reducing straw cutting performance. However, the structure was complicated and the cost was high.
また、藁切り鎌の連結部の上部に外側方に向か
う１枚の板を延設した方式は連結部の下部が取付

雑になつてコスト高になると共に操作が面倒であ
つた。 In addition, the method in which a single plate extending outward from the top of the connecting part of the straw-cutting sickle is similar to the above method because the lower part of the connecting part fits into the mounting frame and there is no supporting member. The cutting resistance causes the plate to tilt, and the means for fitting the plate into the mounting frame from above and the structure for fixing and supporting it with pins become complicated, resulting in high cost and troublesome operation.

にして前述の問題点を解決した。(d) Means for solving the problem The present invention pivots a handling cylinder in a handling chamber having a receiving net,
In a threshing machine, a feed chain and a pinching rail are provided along the handling opening, a swing sorting body is installed below, and a number of straw cutting sickles are attached to the outer periphery of the handling chamber,
The pair of straw-cutting sickles are integrally connected by a plate-shaped connecting part to form a U-shape in plan view, and a pair of upper and lower straw-cutting sickles are provided at the upper and lower parts of the connecting part, respectively, extending outward. The mounting parts of the straw cutting sickle are overlapped on the upper and lower surfaces of the mounting frame, which is integral with the machine frame formed into a square shape, respectively, and bolts are inserted from above into these upper and lower overlapped parts to tighten them. Although the straw cutting sickle can be obtained at low cost, the connecting part of the straw cutting sickle is firmly supported by the upper and lower parts on the mounting frame, so that it can withstand strong cutting resistance. The above-mentioned problems have been solved by allowing easy installation and removal using bolts that are inserted and removed from above.
