[Problem to be Solved by the Invention] In the conventional technique, the receiving hopper is provided outside the upper and lower widths of the housing in which the sorting cylinder is provided, so that the receiving hopper protrudes from the outer surface of the housing, thereby simplifying the outer shape of the body and reducing the size of the housing. It is not possible to easily achieve this, and since the polished rice is directly poured into the polished rice tank from the top of the grading cylinder, the mounting heights of the grading cylinder and the polished rice tank are limited to each other, and the grading cylinder is mounted at a lower position. It is not easy to improve the workability of packing and weighing brown rice by lowering the overall height of the housing or mounting the brown rice tank at a high position, especially improving the work efficiency by shortening the vertical width of the sorting cylinder However, there is a problem that the above-mentioned problem is likely to occur due to the above. Further, as shown in Japanese Patent Application Laid-Open No. 61-64374, a receiving hopper is provided on the upper surface of a housing in which a sorting cylinder is provided, and a frying conveyor for unregulated brown rice is erected along one side of the housing. There is also a technique of providing a browning rice tank on the side of the upper end of the lifting conveyor on the side opposite to the receiving hopper, but a rectangular conveyor in plan view is fixed on the side of the casing having a circular shape in plan view, and the conveyor has a flat surface. Since the side of the round rice pad is fixed, the connection structure between the housing and the conveyor and the connection structure between the conveyor and the brown rice tank cannot be easily simplified. There is a problem that reduction or the like cannot be easily achieved. `` Means for solving the problem '' However, the present invention provides a receiving hopper for charging brown rice, a vertical sorting cylinder for separating scrap rice, and a regular rice tank for receiving the uniform rice extracted from the sorting cylinder, In a grain sorting device that separates input brown rice into regular brown rice and scrap rice and takes out the same, a receiving hopper is provided on an upper surface of a housing in which the sorting cylinder is provided,
The receiving hopper is formed in a substantially square shape in plan view, and an unregulated rice-frying conveyor is erected along one side of the housing. A rice-regulating rice tank is provided, the contour of the rice-regulating rice tank in a plan view is formed into a substantially rectangular shape, and a communication pipe for connecting the inside of the rice-regulating rice tank to the upper surface of the receiving hopper is disposed below the fry inlet of the rice-regulating rice frying conveyor.

A uniform rice-conveying room in which a brown rice-frying conveyor is installed, and a waste rice-conveyor room in which a waste-frying conveyor is installed, and the communication pipe is attached to the upper space of the waste-rice conveyor room. I do. [Operation] Therefore, since the receiving hopper and the rice tanning rice tank having a square shape in plan view are connected to both sides of the rice hulling conveyor, the simplification of the connection structure between the housing, the rice hulling conveyor and the rice tanning tank is easy. In addition to easily improving the connection strength of each part and reducing the manufacturing cost, etc., it is also possible to attach a scraped rice frying conveyor using one side of a regular brown rice frying conveyor, The connecting pipe can be attached using the upper part, and the conveyor and the communicating pipe can be compactly incorporated in the width between the receiving hopper and the brown rice tank to easily improve the sorting workability and the handling operability.
