[0013]

[Explanation of Handling Work] When the grain container C in the stored state is mounted on the loading platform 33 of the transport vehicle 32, the grain container C in the vertical storage posture shown in FIG. 3 is set in the horizontal posture and this posture is locked. Then, as shown in FIG.
Is guided and positioned so as to sandwich the carrier 33 of the carrier 32. Then, while rotating the action shaft 5 by the operation lever 6, the grain container C is lowered and placed on the loading platform 33 as shown in FIG. 1, and when the operation lever 6 is further rotated, it is moved and supported as shown in FIG. The caster 2 of the body A floats above the ground. In this state, by removing the movable support A from the grain container C, the grain container C is mounted and installed on the platform 33.
When all the harvesting work by the combine is completed and the grain container C is stored in the work place or the like, the grain container C on the loading platform 33 is used.
After the movable support A is coupled to the caster 2 so as not to be grounded, the operating shaft 5 is rotated by the operation lever 6 and the elevating and lowering support rod 3 is lowered to ground the caster 2 of the movable support A. When the elevating and lowering support rod 3 is further lowered,
Due to the reaction force, the grain container C floats from the surface of the loading platform 33. In this state, the movable support A is moved to separate from the loading platform 33, or the carrier 32 is moved forward to remove the loading platform 33 from below the grain container C, and then the horizontal grain container C is manually moved. After changing to a vertical posture and locking this posture, it is moved to a predetermined place and stored. Since the moving support A is moved by the casters 2, its traveling direction can be arbitrarily changed, and the side of the grain container C precedes the passage of a narrow place.

[0014]

According to the configuration of the present invention as described above,
The following effects can be obtained. (A) A rectangular grain container is pivotally supported between a pair of left and right moving and supporting means, and can be held in two postures, a horizontal posture and a vertical posture. The lifting and lowering lifter is used for loading and unloading work on a carrier bed. It can be easily performed without the use of special equipment, etc., and since the raising and lowering of the grain container is performed by the rotation operation of the action shaft with the screw part, stepless fine adjustment of elevation can be performed and its action can be performed lightly. Moreover, it can move in a narrow space even in a vertical posture, and the storage space can be greatly reduced. (B) By setting the center of gravity of the grain container on the line connecting the fulcrums of the moving and supporting means, the front and rear balance of the grain container supported between the two moving supports is substantially balanced, and the grain container is floated from the loading platform. The horizontal posture is maintained as it is, and the carrier can be moved to separate the loading platform from the grain container, and the posture can be changed from the horizontal posture to the vertical posture or vice versa with a small force. (C) Further, since the locking means can hold two postures of horizontal and vertical, the grain container can be moved easily and quickly.
