Description

[Detailed Description of the Invention] 1. Field of Industrial Application The present invention is equipped with an endless sorting belt with a large number of horizontal grooves formed on its surface, and the belt is stretched with appropriate inclinations in front, back, left, and right, and the belt is stretched. The present invention relates to a device that sorts soybeans, adzuki beans, etc. by rotating in one direction, and separates unsorted grains such as soybeans into regular grains and waste grains by rolling the upper surface of the belt.

1. Conventional technology Conventionally, as shown in, for example, Japanese Utility Model Application Publication No. 54-99868, a sorting body is provided which is tilted forward and backward and left and right, and a flow regulating member is placed facing the particle size adjustment outlet of the sorting body. There was a technology to adjust the amount taken out.

Problems that the invention aims to solve: The above-mentioned conventional technology lowers the sorting efficiency by increasing the sorting surface of the sorting body to improve efficiency, and also reduces the sorting surface of the sorting body to improve efficiency. This has the problem of reducing sorting efficiency, and while installing a large number of appropriately sized sorting bodies in parallel increases the installation space, it is difficult to maintain the sorting performance of each sorting body uniformly. There is a problem in that it is not easy to improve efficiency and sorting efficiency and simplify handling operations.

Means for Solving Problem 1 Accordingly, in the present invention, a plurality of sorting bodies are arranged close to each other in multiple stages vertically, and a plurality of flow regulating members respectively disposed on each sorting body are connected integrally to control the flow. It is connected and fixed to an adjustment lever, and is configured to be able to simultaneously change the grain size removal width of a plurality of sorting bodies based on the sorting status of the uppermost sorting body.

Therefore, multiple sorting bodies can be installed compactly in one action, and the sorting efficiency and sorting efficiency can be easily improved compared to conventional methods. By keeping the sorting performance of the sorting bodies uniform, it is easy to obtain particles of a constant quality, and because the sorting is adjusted based on the sorting status of the topmost sorting body, handling operations such as operating the flow control lever can be made easier. Simplification can be achieved easily, and the sorting work time can be easily shortened with a simpler work procedure than in the past.
