For example, the operation lever 62 can be turned left while being raised. is there.

[0012]

Next, the operation will be described. The present invention is configured as described above, and when the machine body moves forward, the reaping unit 3 cuts and transports the hull and supplies it to the threshing room of the threshing device 3 to thresh. The goods are stored in the Glen tank 7 from the first thing conveyor via the grain frying device 8, and the stored grains are discharged from the Glen tank 7 from the discharge device 10 to the fryer cylinder 12 for external discharge, Deep-frying canister 12
Is fried and supplied to the discharge auger 13, and the discharge auger 1
3 discharges to the tank of the truck stopped near the field. The discharge auger 13 is attached to an external discharge fryer 12, and the upper part of the external discharge fryer 12 is supported by a reinforcing frame 18. 17, the cereal frying device 8, the fryer for external discharge 12, and the vertical support member 15.
Are connected and fixed by a reinforcing frame 18, and are supported by each other as strength members of each other.
Is also performed stably.

The base of the horizontal arm 20 is fixed to the vertical support member 15 at predetermined intervals in the vertical direction.
0 is attached to a mounting member 22 provided on the rear wall 21 of the Glen tank 7 by a shaft 23, and an urging device 24 is provided between the arm 20 and the Glen tank 7; 35 and the upper lock mechanism 41 are released, and the Glen tank 7 is pulled out of the storage position. First, the urging device 24 rotates the shaft 23 around the first rotation center, and then moves the Glen to the predetermined position. When the tank 7 rotates, the stopper stops the rotation about the first rotation center. Next, since the vertical support member 15 is rotatable with respect to the body frame 1 and the upper mounting member 16, the vertical support member 15 is The Glen tank 7 pivots outward about the two pivots to open and performs maintenance. In this case, the Glen tank 7
Is biased by the biasing device 24 so as to rotate outward to a predetermined position about the shaft attachment 23, so that the Glen tank 7 is fixed to the arm 20 and unexpectedly when in the open state. The work safety is ensured by preventing the movement of the work, and the maintenance can be performed easily.

Further, since the Glen tank 7 is rotated about two rotation centers, that is, a first rotation center of the shaft attachment 23 and a second rotation center of the vertical support member 15, the rotation radius is small. And can be pulled out or stored from a narrow space.
Volume can be increased. Furthermore, since it rotates about two rotation centers, it opens widely and maintenance becomes easy. Then, the maintenance is completed and the Glen tank 7
Is pressed toward the storage position, the Glen tank 7 is fixed to the arm 20 by the urging device 24 in the opposite direction, so that the Glen tank 7 is When it rotates inward and reaches a predetermined position, the rotation of the vertical support member 15 stops, and when the Glen tank 7 is further pressed, the Glen tank 7 is attached to the shaft 23 against the urging device 24.
It is stored by rotating inward about the part. In this case, since the Glen tank 7 rotates inward about the shaft attachment 23, the fitting locus of the discharging device 10 on the Glen tank 7 side to the auger metal 11 on the body frame 1 side is always the same, and the storage operation is performed. Is simple, and it is possible to prevent the Glen tank 7 from unexpectedly coming into contact with the body frame 1 side.

[0015]

The present invention provides a grain tank in which a threshing device 3 is provided above a body frame 1 having a traveling device 2 provided therebelow, and grains threshed by the threshing device 3 are stored on the side of the threshing device 3. In the combine provided with the grain tank 7, the Glen tank 7 is provided with a shaft attachment 23 portion provided in the Glen tank 7 as the first tank.
The body frame 1 is configured to be rotatable as a center of rotation.
A second rotation center capable of rotating the shaft mount 23 serving as the first rotation center is provided at an arbitrary position, and the second rotation center is opened from the storage position around the first rotation center and the second rotation center. Since it is configured to be rotatable between the positions and is attached to the combine tank of the combine tank which is biased by the biasing device 24 to rotate outward about the first rotation center,
Since the Glen tank 7 rotates about two rotation centers of the shaft mount 23 and the vertical support member 15, the rotation radius can be reduced, and the Glen tank 7 can be pulled out or stored from a narrow space. Therefore, the volume of the Glen tank 7 can be increased by miniaturizing the whole or effectively using the space. In addition, since it is pivoted about two pivot centers, it is opened widely and maintenance is easy. Also, since the urging device 24 urges the arm 20 to rotate outward about the first center of rotation, the Glen tank 7 is fixed to the arm 20 and suddenly moves in the open state. , The work safety is ensured, the maintenance can be easily performed, and when the Glen tank 7 is stored, the Glen tank 7 is moved by the arm 2 by the urging device 24.
0, the vertical support member 15
The rotation of the vertical support member 15 is stopped when the Glen tank 7 reaches the predetermined position, and when the Glen tank 7 is further pushed, the Glen tank 7 is rotated by the urging device 24.
The inner tank 23 is pivoted inward about the shaft attachment 23 to be stored, and the fitting locus of the discharging device 10 on the Glen tank 7 side to the auger metal 11 on the body frame 1 is always the same, so that the storing operation is performed. Since it is simple and it is possible to prevent the Glen tank 7 from unexpectedly coming into contact with the body frame 1 side, it is possible to prevent the occurrence of damage accident.
