[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention incorporates a transfer spiral shaft for supplying grains to a diffusion disc, which uniformly supplies the grains to the grain storage chamber for storing the grains by rotating the diffusion disc. The bottom plate of the upper transfer gutter is provided with an adjusting base for adjusting the sliding movement, and a guide gutter having a discharge port at the tip of the adjusting base so as to be rotatable, and displays these adjusting positions. The present invention relates to a grain diffusion supply device provided with a display dial plate.

[0002]

2. Description of the Related Art Grains pumped by a grain raising machine are supplied into an upper transfer door gutter having a transfer spiral shaft therein, transferred by the transfer spiral shaft, and discharged from a supply port provided in a bottom plate to a discharge port. Is supplied to a guide gutter having the same, flows down the guide gutter, is supplied from the discharge port onto a diffusion plate, and is rotationally driven by the diffusion plate to be diffused and supplied into a kernel storage chamber for storing kernels. Is dried by repeated circulation.

[0003]

The guide gutter provided on the bottom plate of the upper transfer door gutter is fixed, and the grain is determined by the degree of moisture of the grain to be dried and the degree of mixing of straw chips, blue rice and pity grains. Although it has occurred that the diffusion plate cannot be evenly diffused into the storage chamber, an adjustment base for mounting a guide gutter is provided, and the adjustment base can be slidably adjusted or the guide gutter can be rotationally adjusted. Is to be adjusted so that it can be adjusted from outside.

[0004]

For this purpose, the present invention relates to a bottom plate 9 of an upper transfer door gutter 6 internally provided with a transfer helical shaft 5 for receiving and transferring grains transported by a grain raising machine 41. The supply port 10, an adjustment base 11, which can be slidably adjusted from the outside, is provided at the supply port 10 of the bottom plate 9, and a discharge port 16, which is rotatable from the outside, is provided at the tip of the adjustment base 11.
