According to the present invention, a chute body for guiding a harvested product into a container is provided so as to be rotatable in the vertical direction, facing the discharge end of the loading conveyor, and the harvested product from the loading conveyor is provided. A guide body for guiding the chute body is provided movably in the left-right direction, and an interlocking mechanism for switching the chute body in the left-right direction while rotating the chute body in the up-down direction is provided. An intermediate movement cam for moving the guide body in the left-right direction at the middle part, a right movement cam for moving the guide body in the left-right direction at a position displaced to the right, and a right-left movement cam for moving the guide body to the left. A left-side moving cam to be moved; and a switchable roller selectively engaged with one of these cams to operate the guide with the selected moving cam. Therefore, the chute body is sequentially raised and rotated by selectively engaging the rollers with one of the intermediate movement cam, the right movement cam and the left movement cam according to the loading operation of the crop. At the same time, the guide body can be switched in the left and right direction by the rotation of the selected cam, and the harvested material discharged from the discharge end of the loading conveyor is distributed to the chute body in the left and right direction by the guide body. It can be guided and carried out, and when loading crops in an inclined state, the crops can be guided toward the high side opposite to the inclination direction with respect to the chute body, and these crops are It can be reliably switched to the front, rear, left and right positions in the container with the chute body and can be stored,
Therefore, in both the loading operation of the crop in the flat state and the loading operation of the crop in the inclined state, it is possible to carry out and store the crop in the container in a flat and even state without shifting in the container. Thus, it is possible to continuously perform the loading operation of the crop without the need for the leveling operation of the crop without manual operation, and it is possible to provide a crop loading device that is preferable in terms of work efficiency.
