As is well known in the art, a configuration in which the rotating barrel 6 can be pivoted outward from the vehicle body 2 with the pivot 6 as a pivot point (this configuration is referred to as a “glen tank open”) is used. In addition, since the above-mentioned first grain bin 8 is attached to the threshing device 3 at the base and the tip is freely inserted into and removed from the upper portion of the Glen tank 4, the Glen tank 4 is opened when the above-mentioned Glen tank is opened. It is configured to be easily detachable.

The discharge spiral shaft 5 has a start end protruding outside the Glen tank 4 so as to be freely engaged with and disengaged from the transmission shaft 15. And the transmission shaft 15 is
It extends to the front side and has an end bearing on a gear box 17 containing bevel gears 16 and 16 '. The gear box 17 is configured to be transmitted by an output shaft 19 of a motor 18 by belt transmission.

Next, as shown in FIG. 4, the lock device 7 is pivotally mounted on the front side plate 20 of the Glen tank 4 by pivotally attaching the operation lever 21 to a lower portion so that a series of operations can be performed. Rod 2
2 is provided so as to rotate, and a lock portion 23 is pivotally mounted on the upper portion. And the connecting rod 24 is the lower swinging rod 22.
And the upper lock portion 23 are connected so as to be interlockable. The swinging rod 22 pivotally connects the intermediate portion a to the front side plate 20, and the lock portion 23 pivotally connects the distal end portion b to the side plate 20.
