Description

Technical Field

[0001] The utility model relates to the field of rice sample screening, in particular to a rice sample screening device. Background Art

[0002] Rice is a finished product made from rice grains after cleaning, husking, milling, and finishing. Rice contains nearly 64% of the nutrients in rice and more than 90% of the nutrients required by the human body. Rice contains about 75% carbohydrates, 7%-8% protein, 1.3%-1.8% fat, and rich B vitamins. The process of separating bulk materials into different particle sizes through one or more layers of screens is called screening. The screening device is a vibration screening mechanical equipment that uses the relative movement of bulk materials and the screen surface to allow some particles to pass through the screen holes, and separates materials such as sand, gravel, and crushed stone into different levels according to particle size.

[0033] Two discharge ports 401 are arranged on the inner bottom surface of the diverter box 4 .

[0034] Through the above technical solution, under the action of the two discharge ports 401, the rice inside can be diverted by the diverter plate 402 and discharged from the discharge port 401 to the inner side of the sieve barrel 504, so that the rice can enter the shell 1 in a quantitative manner and avoid rice accumulation.
