Since it is constrained to set the floor height of the hopper for inputting the grain from below into a predetermined height, the grain release of the grain release machine such as a threshing machine or a rice milling machine where the floor height of the grain discharge port is set low. There was a problem that the grains discharged from the outlet could not be dropped by gravity into the hopper of the vertical grain sorter.

That is, the conventional vertical grain sorter described above is
Since the bottom surface of the shell is closed by the bottom wall, when assembling or removing the two-output gear motor to or from the support plate, it must be put in or taken out of the space S ₀ below the support plate from the side of the shell. The output shaft of the dual output gear motor has a structure that protrudes from the upper surface of the support plate toward the upper side of the shell, so that there is enough height to move the dual output gear motor in the vertical direction in the figure when installing or removing the dual output gear motor. It is necessary to design the space S ₀ , and the floor heights of the supply cylinder and the hopper are accordingly increased.

The present invention has been made in view of the problems of the above-mentioned conventional technique, and the assembling or disassembling work can be easily performed, and the floor height of the hopper is compared with that of the above-mentioned conventional example. The purpose of the present invention is to realize a vertical grain sorter that can be set to a low value.

In the vertical grain sorter, the bottom plate of the shell is provided with a fried helix cylinder, and a rotation drive means for rotating the induction cylinder and the selection net at low speed and rotating the fried helix cylinder at high speed. For inserting and removing the rotary drive means There are opened, the supply cylinder is characterized in that it is constituted by freely bind decompose a pair of semi-barrel freely separation barrel in the radial direction.

Further, the storage tank is provided with a bumper-like handle and support member for protecting the tip end surface of the storage tank, and a machine stand for supporting the shell is provided, and the storage tank under the machine stand is provided. It is effective to dispose a wheel on that side and a horizontal adjustment member for adjusting the horizontal posture on the opposite side.

[0012]

When the assembling or disassembling work is performed, the rotation driving means can be put in and taken out through the hole for putting in and out the rotation driving means provided in the bottom plate of the shell body, so that the rotation on the bottom plate of the shell body It is sufficient for the height of the space for accommodating the drive means to be such that the lower end of the rotation drive means does not project downward from the hole. As a result, the height of the space can be set lower than that of the conventional example, and the height of the floor of the hopper can be set lower.

Further, since the body portion of the guide tube is composed of a pair of half body portions which are separable in the radial direction, the side wall of the shell body 1 is removed and the bottom portion is fixed in the shell body.
