Description

[Detailed description of the invention] The present invention relates to a sample extraction device for a rice hulling sorting device.

In conventional hulling and sorting equipment, adjustments such as the roll spacing between a pair of dehulling rolls placed opposite each other in the hulling chamber are performed to control the amount of paddy collected in the mixed grain take-out trough installed in the rice husk wind sorting chamber at the bottom of the hulling chamber. A sample of the mixed grains of brown rice is collected through an inspection window installed in the wind sorting room machine frame to detect and adjust the dehulling ratio, and also to detect the flow distribution state of the mixed grains on the sorting plate of the sorting device. However, once the paddy has passed through the hulling room, it is also dehulled by the impact of the screw conveyor installed in the grain transport process or the rotary wheel of the grain lifting machine. When detecting the dehulling ratio by collecting a sample from the former mixed grain take-out trough installed at the beginning of the grain transport process, WAffJ errors are likely to occur;
In addition, when detecting and adjusting the dehulling ratio from the flow distribution state of mixed grains on the latter sorting plate that moves in an oscillating manner, specialized knowledge is required, and it is difficult for ordinary farmers to accurately detect the ratio. It had the following drawbacks.
