TECHNICAL FIELD The present invention belongs to the technical field of a cereal container used for carrying cereals harvested in a field to a work place, for example.

[0002]

2. Description of the Related Art In a conventional grain container of this kind, a vertical frame and a horizontal frame form a cubic frame having a rectangular planar shape, and one side axis of the cubic frame is provided inside the cubic frame. A hopper having a bottom plate having a V-shaped cross section is provided along with a grain conveying means mounted on a valley of the bottom plate, and an undulating four-sided member connected to each upper side of the cubic frame is connected to each other. It is provided with a detachable hopper consisting of two side plates,
The grain container thus configured is mounted on a carrier bed of a transport vehicle at the time of harvesting, and is used to transport cereals that have been cut and adjusted by a combine or the like from a field to a workplace.

[0003]

In the prior art as described above, it is necessary to assemble side plates on the upper four sides of the cubic frame at the time of harvesting, increase the yield of cereals, and disassemble the side plates at the time of storage. The side plates that make up the additional hopper are generally relatively heavy because they have a size comparable to the width and length of the carrier of the transport vehicle, requiring not only a lot of labor and time for assembling and disassembling work, but also assembling and disassembling. In handling, the side plates may hit each other and damage each other, and it is inconvenient to store them. In addition, the conventional handling of the seed container at the time of storage is performed by detachably attaching support means having casters at four front and rear positions on the right and left outer sides of the grain container, and on the other hand, lifting and lowering provided at the left and right central portions of the grain container Lifter, acting on the upper surface of the carrier of the carrier, and performing the detaching operation of the lifting caster mechanism in a state where the grain container is slightly raised from the carrier surface,
The grain container is mounted on a carrier or unloaded and stored in a predetermined place. According to such a conventional example, not only is there a cumbersome work for loading or unloading the cereal containers on the transport vehicle, but also when storing them when not in use,
There were inconveniences in handling, such as the need for a large space as it is in the plane shape of the cereal container and the inability to pass through narrow places.

[0004] It is an object of the present invention to provide a cereal container that can easily assemble and store an additional hopper and that can greatly reduce the storage space.

[0005]

Means for Solving the Problems The above object is to form a cubic frame having a square planar shape by a vertical cross frame and a horizontal cross frame, and one side axis of the cubic frame inside the cubic frame. A hopper having a bottom plate having a V-shaped cross section along the direction is formed, and cereal conveying means is mounted on a valley of this bottom plate, while, on the upper four sides of the cubic frame, it is possible to undulate respectively. An additional hopper constituted by side plates pivotally supported is provided, and one pair of opposite side plates constituting the additional hopper is folded and stored in a horizontal posture in the upper part of the hopper, and the other pair of opposite side plates is provided. The cubic frame is configured to be foldably supported on an upper horizontal rail that constitutes the cubic frame, and is provided at a lower portion of one side of each of the side plates that is foldably supported on the horizontal rail, when the side plate is in a standing posture. On the outer surface of the upper horizontal rail This is achieved by providing a lock plate that automatically engages and automatically disengages when in the folded position. The object of the present invention is to provide a cubic frame according to claim 1, wherein the upper and lower side frames are folded and supported on an upper horizontal frame, and the upper and lower vertical frames of the side plates are adjacent to each other in a standing posture. This is achieved by providing a connecting means for stopping and establishing the additional hopper attitude, and engaging the upper horizontal rail constituting the cubic frame body in the folded storage attitude of all the side plates to establish the storage attitude. You. The above object is achieved by claim 1 or claim 2, wherein the cubic frame body is folded and supported on one of the side plates forming the hopper, and the cubic frame is cubic when the side plate stands upright. A lock plate is provided which automatically engages with the outer surface of the upper horizontal frame of the frame and automatically releases the engagement when in the folded position. This is achieved by being formed of an elastic material having an automatic return behavior that follows the outer surface of the horizontal cross frame of the cubic frame when pressed into contact with the outer surface of the frame and shifts to the folded position. The above object is achieved by any of claims 1 to 3, wherein a movable support means having a bogie structure is removably pivotally connected to substantially the center of the left and right sides of the cubic frame body, and the cubic frame body is attached to both movable support means. Can be maintained and maintained in two postures, a horizontal posture and a vertical posture,
On the other hand, the two moving supporting means are provided with a base frame provided with casters, a supporting means capable of vertically moving a cubic frame vertically suspended at the upper center of the base frame, and establishing a horizontal and vertical posture of the cubic frame. This is achieved by the configuration with the coupling means.
