  The rotational power of the engine 14 is such that an engine pulley 14b pivotally supported on the engine shaft 14a and a transmission case 34 provided on one side of the threshing machine 5 are provided with a transmission mechanism 34a provided on one side thereof. The input pulley 34c pivotally supported by the input transmission shaft 34b is stretched over a belt 14c to input engine rotational power to the transmission case 34. As shown in FIG. 7, the transmission case 34 is provided so as to be mounted above the inlet funnel 16j, and is provided so as to be positioned on the right side of the dust removal cylinder 33b, so that the handling cylinder 16a, the dust collection cylinder 33b, and the like are driven to rotate. It is.

  The output transmission shaft 34d of the transmission mechanism 34a of the transmission case 34 is provided with a two-stage grooved output pulley 34e, which is pivotally supported to the inner groove of the output pulley 34e and the shaft end of the dust removal shaft 33a. A belt 33e is stretched around the dust removal pulley 33d, and the dust removal drum 33b is rotationally driven.

  A belt 16h is spanned between the outer groove of the output pulley 34e of the output transmission shaft 34d of the transmission case 34 and the handling pulley 16f pivotally supported on one end of the handling shaft 16a. It is the structure which rotates.

  As a result, the transmission configuration is simple and the cost is reduced. Conventionally, since the dust removal shaft 33a is directly transmitted by the bevel gear type transmission mechanism 34a of the transmission case 34, it is weak against impact, but this can be solved.

  As shown in FIG. 6, a belt 16h for rotationally driving the handling cylinder 16b in the transmission mechanism diagram may be provided so as to be located on the inner side of the belt 33e for rotationally driving the dust collecting cylinder 33b as shown in FIG.

  As a result, the handling cylinder safety cover that covers the belt 16h of the handling cylinder 16c can be reduced in size.
