Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a foreign matter sorting device such as a grain conditioner, and can be used in a huller, threshing machine, dryer, etc.

Problems to be Solved by the Invention Grain conditioning machines attempt to sort and process supplied grains according to their purpose. In addition, grain is generally fed using a grain frying machine, etc., and when removing foreign matter during the grain frying process or during the process, the dust etc. in the grain is is emitted outside the machine, making the barber feel unhygienic and uncomfortable, as well as being troublesome to remove the foreign matter, making it difficult to work comfortably.

Means for Solving the Problem This invention provides a method for preventing foreign matter from leaking through the net (2) from one end to the other end of the net (2) which receives and leaks grains fed by a grain lifting machine (1). The structure of a foreign matter sorting device such as a grain conditioner is provided with a foreign matter discharge port (4) having an on-off valve (3) that can be opened by the pressure of .

Functions and Effects of the Invention The grain fed from the grain lifting machine (1) is received by the net (2), and the grains are moved by the inertial force of the grain lifting machine (1) and by sliding on the surface of the net (2). The foreign matter that does not leak through the mesh of the net (2) is guided to the upper end discharge port (4). The pressure of the guided foreign matter automatically opens the on-off valve (3) and discharges the guided foreign matter out of the machine to perform foreign matter sorting. When the foreign matter is discharged from the discharge port (4), the on-off valve (3) 3) closes to effectively separate the grains from the net (2), which automatically separates and discharges foreign substances that may be mixed into the grains and interfere with the sorting process in the next process. To enable comfortable continuous work without troubling the operator's hands and without blowing out dust or the like during work.
