The dust that has been sucked out and discharged by the platform auger
(21) is taken back to feeder house (18)
It is without any such problems.

A harvesting switch (40) or a stop switch (42), which is a sensor for turning on and off the suction / discharge fan (26) by starting or ending the operation.
The feeder is controlled by automatically controlling the operation of the suction / discharge fan (26) according to the proper judgment of the harvesting operation status, and restricting and operating the suction / discharge fan (26) only when necessary. The suction and discharge of the house (18) is performed, and when unnecessary, the suction and discharge of the dust is stopped by automatically stopping the suction and discharge fan (26), thereby improving the discharge function of the feeder house (18) and the handling operability. .

Further, by automatically stopping the dust suction and discharge fan (26) when the cutting section (9) is raised, and by raising the cutting section (9) when turning in a field, the fan (26) is automatically stopped. The dust adhering to the suction side falls down by its own weight and is removed, thereby preventing dust clogging such as branch spikes on the suction side of the fan (26) and properly maintaining the suction and discharge efficiency.

Further, a stop switch (42) is provided which is a lift sensor for automatically turning on and off the dust suction and discharge fan (26) upon detecting the lifting and lowering of the cutting unit (9). The fan (26) temporarily stops, and the culm or pod attached to the suction side of the fan (26) falls off and is carried out to the threshing unit (4). (26) automatically operates again, so that the operator does not need to turn the fan (26) on and off when changing directions at the headland on the field, etc., thereby improving the dust discharging function and the handling workability. .

Further, the suction surface of the suction / discharge fan (26) is opposed to the suction port (28), and a dustproof net (29), which is a net body for preventing suction of a culm or the like, is provided in the suction port (28). (18) The suction and discharge fan (2) can form a maximum outer diameter substantially equal to the width of the feeder house (18) on the outer side of the upper surface
6) is installed, the vertical width of the feeder house (18) is formed to the minimum size necessary for transporting the cut grain, and the diameter of the suction / discharge dust fan (26) is increased and the rotation is reduced. ) To reduce the suction pressure of the dust suction port (28), prevent suction of culms or pods, secure the suction power of earth and sand dust, and prevent suction and discharge of grain culms or grains. Improve the dust capacity.
