(Problem to be Solved by the Invention) However, according to the above structure, the feeding position at which the feeding roll is rotated is a position through which the feeding recess passes, and is always the same in the axial direction of the feeding roll. It was passing through the location. Therefore, if the seeds do not fall smoothly from the top, they may not be accommodated in the recesses, leading to the possibility of grain loss.

During such work, when the feed roll 18 is rotated in the circumferential direction by the drive shaft 19, the feed roll 18 is rotated and reciprocated in the axial direction.
Since the concave portion 26 of 8 is reciprocated within the width of the feeding passage 17 while rotating in the circumferential direction, it is possible to effectively scoop and feed out the seeds within the width of the feeding passage 17, thereby preventing missing grains. It can be prevented. Furthermore, compared to the conventional structure in which seeds are scooped up at a fixed position in the feeding passage 17, since the seeds are scooped within the reciprocating range, that is, approximately across the length 11 of the feeding passage 17, the occurrence of bridging is effectively prevented. In addition, the occurrence of blisters can be prevented due to vibrations caused by the reciprocating movement of the feed roll 18, and from this also, missing grains can be effectively prevented. Therefore,
Stable seed feeding can be performed.

A compression spring 36 is interposed on the other support cylinder 28 side, and is configured to elastically bias the cam surface 34 and the engagement shaft 35 toward one side so that they come into contact with each other. Further, a transfer roller may be provided at the end of the engagement shaft 35 so that relative sliding with the cam surface 34 can be made smoother.
