Patent Document 1: Japanese Patent Publication No. 2004-321061

In the self-harvesting type roll baler of Patent Document 1, since the direction in which the chute feed crop is discharged is the direction in which the feed crop is put in from the upper side with respect to the upper opening of the hopper, the harvester moves up and down depending on the harvest situation of the feed crop. When moving, there was a problem in that the angle of the direction in which the chute was discharged by the chute according to the harvesting season shifted, thereby displacing the position of feeding the fodder into the hopper.

If the feed position of the feed crops into the hopper is misaligned, the feed crops are not put into the optimal area within the hopper to store the feed crops evenly, resulting in a problem that the feed crops cannot be evenly stored in the hopper. .

Particularly, in the case of a hopper having a diffusion part that is spread so that the feed crop is brought into contact and stored evenly inside the hopper, the input feed crop does not come into contact with the diffusion part and does not spread as it is, but does not diffuse and falls into the hopper. Thereby, there is a problem that the feed crops stored in the hopper are largely biased.

When the feed crop is biased and stored in the hopper, the feed crop transferred from the hopper to the conveying conveyor is not evenly loaded on the conveying surface of the conveying conveyor, and is inputted in a biased state relative to the molding chamber from the conveying conveyor. There was a problem in that the density of the roll bale was not uniform, and the deformed roll bale or the roll bale prone to mold collapse was molded.

The present invention is to tackle such a problem as an example of the subject. In other words, even if the angle change in the direction of discharge of the crop of the chute occurs along the shanghai of the harvester, it is possible to equalize the storage of the feed crop inside the feeder, whereby the feed crop is evenly distributed to the molding room. It is an object of the present invention to be able to inject it, and to be able to form a roll bale of a normal shape or a roll bale that is difficult to form collapse.

In order to achieve this object, the self-harvesting roll baler according to the present invention has at least the following configuration.
