  The waste spike tip chain 40c and the waste root transfer chain 41a are configured to shift by the transmission motor 43, the transmission 43a, and the like, and below the waste root transfer chain 41a, An evacuation pinching rod 44 is provided, and the stocker side of the culling is pinched and transferred between the kerchief excavation root transfer chain 41 a and the excretion pinching rod 44.

  As shown in FIG. 28, the evacuation pinching rods 44 are provided with support rods 44a at predetermined intervals, and each support rod 44a on one side is provided with a spring 44b. A lift amount detection sensor 44c for detecting a downward push-up amount is provided, and the lift amount detection sensor 44c is provided at the transfer start end of the waste root transfer chain 41a. As shown in FIG. 29, the rotational speeds of the waste spike tip chain 40c and the waste root transfer chain 41a are sequentially increased to a high speed, as shown in FIG. The change control is performed by a control device 35d provided in the interior.

  Accordingly, the clogging of the waste can be prevented by changing the rotational speed of the waste spear tip chain 40c and the waste root transfer chain 41a according to the amount of waste to be handed over. In addition, the layer thickness of the waste can be made constant.

  As shown in FIG. 30, the speed change mechanism device 45 that drives and rotates the waste root tip chain 40 c of the waste root transfer device 40 and the waste root source transfer chain 41 a of the waste root transfer device 41 is arranged in the threshing device 5. It is provided on the rear side. The rotational power to the transmission mechanism device 45 is passed over a belt 42b between a pulley 8d provided on the barrel shaft 8b and an exhaust pulley 42a provided on an input shaft 45b of the gear case 45a of the transmission mechanism device 45. The belt 42b is provided with a tension device 46, and the rotational power of the barrel cylinder 8b is input by the belt 42b.

  The input shaft 45b and the output shaft 45c of the gear case 45a are provided so as to support the gears 46a and 46b for shifting, and the rotational speed of the shifting shaft 47 is switched by operating the shifting lever 46c. Yes, it is a configuration for switching the rotational speeds of the culm tip chain 40c and the culm root transfer chain 41a.

Thereby, even when the amount of transport waste is different due to the difference in crop conditions, it can be easily handled. In addition, it is possible to stabilize the transport performance by making the layer thickness of the waste amount substantially constant.
As shown in FIG. 27, FIG. 31, and FIG. 32, a speed increasing switch 44d and a speed reducing switch 44e for switching the rotational speeds of the waste head transfer device 40 and the waste root transfer device 41 are provided on the left side. Is provided at the front of the operating device 35a. The detection and non-detection of the lift amount detection sensor 44c and the "ON"-"OFF" operation of the acceleration / deceleration switches 44d, 44e are input to the control device 35b of the operation device 35a, based on the input to the speed change motor 43. However, the control device 35d controls the start and stop. In addition, each of the switches 44d and 44e can be operated while seated on the cockpit 35b.

  As a result, the gear shifting operation can be performed while the cereal reaping operation is performed, and the operability is improved.
