Rice screening device for removing impurities used in agricultural planting

Abstract

The invention discloses a rice screening device for removing impurities used in agricultural planting. The rice screening device comprises a box body. A feeding funnel is inserted into one side of theouter wall of the top of the box body. A discharge pipe is arranged at the top of one side of the box body. Connecting sleeves are arranged on the top of the inner wall of both sides of the box body.And the same first sieve plate is arranged on one side of the two connecting sleeves away from the box body. Connecting springs distributed in equidistant are arranged on the intermediate position ofboth sides of the first sieve plate. A first vibration motor is arranged on the intermediate position of the bottom of the first sieve plate. A transition funnel is arranged on the top of the inner wall of the box body, and the transition funnel is located on the bottom of the first sieve plate. A through hole is formed in the intermediate position of the inner wall of one side of the box, and ablower is arranged on the inner wall of the through hole. The rice screening device for removing impurities used in agricultural planting can conveniently screen out large particles and small particles of the rice and light-weight impurities, completely remove the impurities, is convenient and easy to operate, is convenient for discharging rice after the screening, and has a drying function.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a rice screening device for agricultural planting which is convenient for removing impurities. Background technique [0002] At present, rice occupies a pivotal position in agricultural planting. After the rice is mature, it needs to be processed into rice for people to eat through multiple processes. The rice processing process is generally divided into cleaning, ridge paddy, rice milling and finished product processing. One of the main processes in processing, cleaning and screening is the key process of rice processing. At present, the structure of the commonly used rice screening device is that two layers of screens arranged up and down are arranged obliquely on the inner wall of the screen box, and the impurities of large particles and small particles are screened out respectively, and the light impurities in the rice cannot be screened. Separated, resulting in incomp...

AI Technical Summary

Problems solved by technology

At present, the structure of the commonly used rice screening device is that two layers of screens arranged up and down are arranged obliquely on the inner wall of the screen box, and the impurities of large particles and small particles are screened out respectively, and the light impurities in the rice cannot be screened. Separation, resulting in incomplete removal of impurities, and the existing rice screening device has a single function when used, and does not have a drying function
