う構成されている。 That is, large diameter portions 8a, 8a are provided at the ends of both support shafts 8, 8.
At the same time, by fitting the large diameter portions 8a, 8a onto the gear case 10, grains are prevented from entering between the support shaft 8 and the gear case 10, and the end of the spiral body 9 on the gear case side By forming a notch 9a in the outer part of the spiral body 9 and making it possible to rotate on the outer side of the spiral body 9 without interfering with the gear case 10,
The outer part of the gear case 10 is also configured to feed grains.

However, even if the conveyance structure of the bent part is configured as described above, the notch cannot be made very large due to strength problems. In this case, the distance between the overlapping spirals on the outside of the gear case is limited, so the conveyance capacity on the outside of the gear case may be reduced, and furthermore, the flow of grains at the stepped portion formed in the large diameter portion is limited. There is room for improvement as this hinders
本考案の目的は合理的な改造で、屈曲部が形成
された搬送系において、該屈曲部での穀粒の搬送
だけ良好に行われる構造を得る点にある。 An object of the present invention is to obtain, by rational modification, a structure in which grains are transported only at the bent portions in a conveying system in which bent portions are formed.

果は次の通りである。
The feature of the present invention is that in the grain conveying device having the above configuration, the outer diameter of the gear case is set smaller than the outer diameter of both support shafts, and the ends of both support shafts are fitted onto the gear case. The gear case side end portions of the spiral body are placed close to each other, and their functions and effects are as follows.

Therefore, by setting the relative size relationship between the gear case and the support shaft, the ends of both spiral bodies can be placed close to each other without forming a notch in the spiral body, and grain transportation at the bending part is facilitated. A structure was obtained in which the process was carried out well.
