Vibrating screening device

Abstract

The invention discloses a vibrating screening device. The vibrating screening device is characterized in that raw grains are vibrated and screened through a screening plate obliquely arranged in a screening bin, so that the purpose of removing impurities in the raw grains is achieved; particularly, in order to avoid the phenomena that the raw grains are caked and accumulated in the screening process and the impurity cleaning effect is poor, a spreading and cleaning mechanism is arranged in cooperation with the screening plate; after the raw grains are spread and pushed on the screening plate through the spreading and cleaning mechanism, the screening plate can quickly screen and remove the impurities through vibration; and the spreading and cleaning mechanism is used for cleaning the impurities (rice, wheat or oat and other raw grains are easily clamped in sieve holes to block the sieve holes) clamped on the sieve holes, and therefore, the purposes of improving the cleaning effect and the screening efficiency are achieved.

Description

technical field [0001] The invention relates to screening and cleaning equipment, in particular to a vibrating screening device. Background technique [0002] In grain and oil processing industries such as milling, feed or oil extraction, it is necessary to vibrate and sieve raw grains to effectively separate dust and light impurity particles in granular materials such as wheat, corn, rice or oil. Existing screening and cleaning equipment mostly use round cage sieves and double-layer vibrating screens for screening. Among them, the cleaning speed of round cage sieves is slow and the cleaning effect is poor. It is mostly used for vibrating screening of corn kernels, while the double-layer Although the cleaning speed of the vibrating screen is fast, it is necessary to replace the sieve plates of different sizes for different materials in order to be able to clean and screen normally. Work cannot be carried out smoothly. Contents of the invention [0003] The present invent...
