Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hulling and sorting machine having a shedding device, a swinging sorting device, etc., and more particularly relates to a sampling device for grains sorted on a grain selection plate in the swinging sorting device. .

Conventionally, in the seed oscillating sorting device, the amount of grains such as brown rice and paddy that are sorted and flowed down on the grain sorting plate is controlled by the rim, tosui, etc. installed near the grain sorting plate, respectively. Since the structure was such that the height of the grain layer on the grain selection board was detected in two values, high and low, by means of the Therefore, the more advanced grain amount detection means described above cannot detect the exact amount of brown rice, paddy, etc., or the shedding rate. When automatically controlling each process,
The disadvantage is that fine control cannot be performed.

Therefore, the present invention provides two partition plates at the lower end of the grain flow of the grain sorting plate of the oscillating sorting device to separate the grains sorted into brown rice, mixed rice, and paddy and transfer them to the next process. A grain sampling cylinder is provided in each compartment separated by the partition plate and corresponding to the grain flow lower end of the grain selection plate, and the sampled grains are guided to the detector, respectively. It is an object of the present invention to provide a sampling device for grain selection board grains in a hulling and sorting machine, which is capable of sampling the amount of grains accurately proportional to the respective flow rates of brown rice, mixed rice, and paddy flowing down from the grain selection board. This is a book that does.
