Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses a grain sorter that separates brown rice, etc. after hulling into sized grains and immature grains. The present invention relates to a grain selection angle control device.

In general, when the amount of immature grains mixed in with brown rice increases, the product value decreases, while by reducing the amount of immature grains mixed in, grain sorting efficiency decreases and the amount of brown rice (product) taken out decreases. Although there was a problem, conventionally, the grading after grain sorting was determined visually by the operator, so
It is difficult to always obtain a constant judgment standard, and there is a problem that the proportion of immature grains included in grading after grain selection becomes uneven.

The present invention addresses the above-mentioned problems, and is equipped with a grain sorting cylinder that is continuously rotated to separate the sorted grains and immature grains, and the grain sorting cylinder is supported by tilting the grain removal side downward. In the apparatus, a grain sorting angle adjusting member for changing the grain sorting angle of the grain sorting tube and an immature grain sensor for controlling the operation thereof are provided, and a grain selection angle adjusting member for changing the grain sorting angle of the grain sorting tube and an immature grain sensor for controlling the operation thereof are provided, and a grain selection angle adjusting member for changing the grain sorting angle of the grain sorting tube and an immature grain sensor for controlling the operation thereof are provided. It is equipped with a sample grain sorter for extracting immature grains, and the immature grains from this sample grain sorter are detected by the sensor, and a change in the amount of immature grains included in the sorting from the grain sorting cylinder is detected. By automatically changing the grain sorting angle of the grain sorting tube based on the sensor output, immature grains can be efficiently removed without reducing the product value, and the grain sorting work efficiency for obtaining well-sorted grains is improved compared to conventional methods. In addition, by extracting a part of the sorted grains from the grain sorting cylinder to the sample grain sorter, it is possible to properly detect changes in the amount of immature grains included in the sorted grains, and A grain sorting angle control device for a grain sorting machine that can easily set the reference value of the mixed amount of grains, etc., and can quickly respond to the grain sorting control operation during continuous grain sorting operations to obtain extremely accurate grain sorting angle control values. This is what we are trying to provide.
