Description

  The present invention relates to a general-purpose combine that throws all of the harvested cereals into a threshing apparatus and performs a threshing process.

The general-purpose combiner has a configuration in which cereals harvested by a harvesting device are collected together by an auger and supplied to a threshing device by a feeder for threshing treatment.
During the harvesting operation using this general-purpose combiner, there is a problem that dust rolls up from the cereal and the front view of the aircraft from the cockpit becomes worse and the efficiency of the harvesting operation is reduced. In order to prevent this, for example, Patent Document 1 discloses a technique in which dust is sucked from the mowing device side and discharged to the rear of the machine body by a dust exhaust fan provided on the side surface of the feeder case surrounding the feeder.
