At this time, since the bogie frame has wheels, the weight balance between the front and rear of the main body of the harvester is not lost even if the harvested material is contained in the container on the carrier frame, so that the bogie can be smoothly moved. Thus, the number of replacements of the container can be reduced by using a container having a large capacity, and the work efficiency can be improved.

Further, at the time of carrying out the container in which the harvested product is fully stored, the fixing of the carrier frame is released by the fixing means, and the carrier frame is lifted and pivoted about the shaft supporting portion with the carrier frame. In addition, the carrier frame can be easily inclined in the carry-out direction of the container, and the container can be smoothly carried out from the inclined carrier.

At this time, since the carrier frame can be smoothly carried out by lifting and rotating the carrier frame around the pivotal support portion with respect to the carrier frame, a hydraulic device such as a hydraulic cylinder is used for the rotating means of the carrier frame. The handling operation is easier than the one used, the configuration is simple as a whole, and the cost merit is great.

Further, after the carrying-out of the container, the carrier frame is returned and rotated about the shaft supporting portion with respect to the carrier frame, so that the carrier frame can be easily horizontally supported on the carrier supporting portion of the carrier frame. As well as being ready for the next crop.

According to the second aspect of the present invention, since the container is formed of a flexible bag having an accommodating port, the harvest is sufficiently accommodated in the bag due to the flexibility deformed by the harvest when the harvest is stored. When the harvest is stored, the bag is not damaged by the bag, and when not in use, it is not bulky and easy to handle by folding it when not in use. Compared to a storage container having a shape that retains its shape, the container is not bulky, is easy to handle, and can be obtained at low cost.

Further, since the support is formed of an annular ring which is disposed and fixed above the loading platform and which supports the opening of the storage opening of the bag placed on the loading platform, the support is mounted on the loading platform by this annular ring. The storage opening of the bag to be placed can be easily supported in the open state, and the harvest can be easily stored in the bag until the harvest is filled from the storage opening.

According to the third aspect of the present invention, the loading frame is set at a position slightly behind the vertical axis passing through the center of the annular ring as the pivot point, so that the bag body on the loading frame of the loading frame is formed. Even if the loading frame is released when the crop is stored, the weight of the bag housing the crop can reliably prevent the loading frame from jumping up and turning, and the crop is stored. It is possible to prevent an unexpected situation from occurring when the bag is carried out.

According to the fourth aspect of the present invention, the bogie frame is rotatably supported on the main body of the harvester in the vertical direction. Therefore, when moving between fields, the bogie frame is lifted and rotated. By rotating the entire cart toward the harvester main body, the cart can be easily moved between fields.
