Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a vertical grain sorter that shells grains and sorts the grains with a net rotating around a vertical axis.

``Prior art'' As a conventional vertical grain sorter, for example, the 15th
There is something like the one shown in the figure.

As shown in the figure, a hopper 2 is provided at the back of the outer shell 1 to input unsorted grains, while a hopper 2 is provided at the front for temporarily storing the refined grains, and a bag body (in both cases) is placed on the weighing machine. A storage tank 3 is provided for discharging the water to a tank (not shown).

Conventionally, the storage tank 3 and the hopper 2 have been fixed in their relative positions, such as front and back, or front and side.

``Problem that the invention aims to solve'' However, with conventional vertical grain sorters like this, the relative position of the hopper and storage tank is fixed from the beginning, so the installation location cannot be freely selected. They were often installed in small spaces, reducing work efficiency, or forced into large spaces.

The present invention was made in view of these conventional problems, and aims to provide a vertical grain sorter that can freely change the relative position of the hopper and the storage tank.

"Means for Solving the Problem" The gist of the present invention to achieve this purpose is to include a cylindrical sorting net inside an outer shell erected on a base; A grain lifting spiral fitted inside the sorting net is provided concentrically and rotatably relative to each other, and a storage tank for temporarily storing grains fried by the grain lifting spiral is provided in the outer shell. In a grain sorting machine, the grain sorting machine is provided with a hopper that projects outward from the top of the hopper and charges unsorted grains into the vicinity of the base of the outer shell, the outer shell being placed near the upper edge line of the hopper. It is composed of an upper outer shell body and a lower outer shell body which are divided into two parts at the upper part, and a flange having a circular inner circumference or outer circumference or a circular inner and outer circumference is provided on the upper edge of the lower outer shell body, and A flange or a stopper member is provided near the lower edge to abut the flange of the lower outer shell and to hold the upper outer shell concentrically and rotatably with respect to the lower outer shell; The apparatus is provided with a fixing means that loosens when rotated and fixes during use, and is attached near the lower edge of the interior of the upper shell body, and is used to collect small grains that fall after being sorted by the sorting net. In order to prevent grains from accumulating on the holding part formed by a flange, the vertical grain sorting machine is characterized in that a funnel-like small grain guide that covers the holding part and is open in the lower shell body is provided.

``Operation'' Once the installation location of the vertical grain sorter has been determined, determine the orientation of the hopper and storage tank that is most suitable for the location. Then, loosen the nut at the hem of the upper outer shell and orient the upper shell in the desired direction. Then, tighten and secure the nut.

Even when it is desired to change the above-mentioned relative position, the orientation of the upper outer shell body can be freely changed in the above-described manner.

Since you can freely choose the mutual orientation of the hopper into which a large amount of unsorted grain is fed and the storage tank where the scale is placed below, you can increase work efficiency regardless of the installation location and even if installed in a narrow space. .

"Embodiments" Hereinafter, various embodiments of the present invention will be described based on the drawings.

Next, the turning guide portion 30 for turning and fixing the upper outer shell 13 relative to the lower outer shell 12 will be explained with reference to FIGS. 2 to 6.

A lower flange 31 is provided at the upper edge of the lower outer shell 12.
Further, an upper flange 32 is provided at the lower end edge of the upper outer shell 13. These upper and lower flanges 31, 3
As shown in FIG. 3, in which 2 represents approximately one-fourth of the planar figure, the outer periphery is square in accordance with the inner periphery of each outer shell, and the inner edge is circular.

Further, a center holding ring 33 is welded to the upper surface of the inner edge of the lower flange 31 to prevent it from shifting laterally when the upper outer shell 13 turns.

On the other hand, one fixing member 34 for fixing the upper and lower flanges 31 and 32 is arranged on each surface of the outer shell.

The fixing member 34 has a hook shape as shown in FIG. 5, and a back nut 35 is welded thereto. A through hole 13a for a thumbscrew 36 that is screwed into a back nut 35 of the fixing member 34 is provided near the center of the lower end of each surface of the upper shell 13.

Further, as shown in FIG. 2, a funnel-shaped small grain guide 37 is provided near the inner lower end of the upper shell body 13 to prevent falling small grains from getting caught in the turning guide part 30. .
