Abstract
Description
Technical Field

[0002] Rice is a kind of food made from paddy rice after various processes such as milling, husking and screening. It is one of the staple foods in daily life. It contains many nutrients needed by the human body. For example, it can supplement carbohydrates for the human body, provide energy and restore physical strength.
[0003] Most rice screening machines are composed of multiple components such as the screening machine body, screen, vibrator and motor. When in use, rice is put in through the feed port and finally falls onto the screen. The vibration force is transmitted to the screen through the vibrator to screen out the debris and impurities contained in the rice, such as stones, straw, hemp rope, etc.
[0004] The feed port of the common rice screening machine is generally set on the top or one side of the machine body to facilitate operation and material addition. However, the rice tends to lean to that side due to gravity, which can easily cause the rice to accumulate or clog in a certain area of the screen plate, reducing the utilization rate of the screen plate. In order to maintain the screening effect, the vibration amplitude or frequency of the screen plate needs to be increased, which increases the energy consumption of the equipment.
