  An example of a combine according to the present invention will be described.

[Overall structure of combine]
1 and 2 are a perspective view of the combine 100 according to the present embodiment as viewed from the left front and a perspective view as viewed from the right front, respectively. In the figure, the front-rear direction, the left-right direction, and the up-down direction of the combine 100 are indicated by arrows.

  The combine 100 is mainly composed of a traveling device 1, a reaping device 2, a threshing device 3, a sorting device 4, and a storage device 5.

  The traveling device 1 is provided below the chassis frame 10. The travel device 1 includes a transmission (not shown) and a pair of left and right crawler devices 11. The transmission transmits the power of the engine 90 (see FIG. 8) to the crawler device 11. The crawler device 11 causes the combine 100 to travel in the front-rear direction, or turns the combine 100 in the left-right direction.

  The reaping device 2 is provided in front of the traveling device 1. The reaping device 2 includes a reel 21, a cutter (cutting blade) 22, an auger (lateral feed screw) 23, and a feeder 24. The reel 21 guides the cereal straw in the field to the cutter 22 by rotating. The cutter 22 cuts the cereal bowl guided by the reel 21. The auger 23 collects the cereals cut by the cutter 22 at a predetermined position. The feeder 24 supplies the cereals harvested by the reaping device 2 to the threshing device 3 via the feeder house 25. The feeder house 25 has a built-in conveyor for conveying the cereals collected by the auger 23 to the rotor.

  The threshing device 3 is provided behind the reaping device 2. The threshing device 3 includes a handling cylinder, a receiving net, and a front rotor. The handling barrel threshs the cereal by rotating. Moreover, the handling cylinder conveys the cereal by rotating. The receiving net supports the cereal bowl conveyed by the handling cylinder and drops the cereal to the sorting device 4. The front rotor feeds the cereal straw that has been conveyed by the feeder 24 to the threshing device 3. Moreover, the front rotor not only conveys the cereal but also has a function of performing preliminary threshing (pre-threshing).

  The sorting device 4 is provided below the threshing device 3. The sorting device 4 includes an oscillating device and a blower device (karasu). The oscillating device sifts through the cereal and sorts the grain. The grain selected by the rocking device is conveyed by the grain conveying device, and is put into the glen tank 51 through the charging port. The blower device assists the selection of the grains by blowing away foreign substances such as sawdust included in the threshing. Contaminants such as sawdust are discharged to the outside from a discharge port (not shown) provided behind the sorting device 4.

  The storage device 5 is provided on the right side of the threshing device 3 and the sorting device 4. Therefore, the threshing device 3 and the sorting device 4 and the storage device 5 are arranged in parallel on the left and right above the chassis frame 10. The storage device 5 includes a Glen tank 51. The Glen tank 51 stores the grains that have been conveyed from the sorting device 4. The discharge auger 52 is used when discharging the grains in the grain tank 51. The discharge auger 52 is configured to be rotated in the vertical and horizontal directions when performing the grain discharging operation, so that the grain can be discharged to an arbitrary place.
