摘要： PURPOSE:To simply and easily perform replacement of a sprocket by mounting a mounting flange externally fitted to a drive shaft in an integrally rotating condition, and bolt-connecting the sprocket to a side surface which is in a machine body right/left direction outer side of the mounting flange. CONSTITUTION:A mounting flange 6A is spline-externally fitted to an axle also mounted by a coming off-stop bolt 27, to connect a sprocket 6B by a bolt 25 to a side surface which is in a machine body right/left direction outer side of the mounting flange 6A, and a drive sprocket 6 of two-part divided structure is formed. In replacing the drive sprocket 6, replacing only the sprocket 6B in the outer side is required, here to stop a crawler belt 26, after the sprocket 6B is removed, hooked to a flange part 6a of the mounting flange 6A. Consequently, work of mounting the sprocket 6B of the next new part in the mounting flange 6A is easily performed by a light operation.

摘要： PROBLEM TO BE SOLVED: To provide a threshing apparatus for a combine harvester sufficiently usable simply by exchanging a broken semielliptic metal with a new one even when only the semielliptic metal is broken. SOLUTION: This threshing apparatus for a combine harvester is obtained by stretching a receiving net 11 composed by attaching a crimped net 16 to a supporting frame 17 along the outer periphery on the lower side of a threshing cylinder 10. Each semielliptic metal 24 is arranged in a posture directed in the peripheral direction of a threshing cylinder 10 on the crimped net 16 and short cylindrical bosses 31 are installed between a net pressing plate 25 integral with the semielliptic metal 24 and a wear plate 26 in which the position is regulated in the shaft center direction of the threshing cylinder 10 in each crosspiece part 17D of the supporting frame 17. The net pressing plate 25 and the wear plate 26 are fastened and fixed in a state thereof regulating the mutual interval constant with the bosses 31 by screw members 27 inserting the bosses 31 therethrough.
