Abstract

The invention discloses a grain winnowing vibration screen. According to the structure of the grain winnowing vibration screen, a feeding hopper (1) is arranged on the top of a rack (13), an air closing material evening device (2) is arranged below the feeding hopper (1), a discharging flowing plate (3) is arranged below the air closing material evening device (2), and the lower end of the discharging flowing plate (3) is located at a suction opening of a front suction channel (401) of a winnowing cleaning device (4); a material distributing device (17) is arranged below the discharging flowing plate (3), an upper screen feeding flowing plate (6) and a lower screen feeding flowing plate (7) are arranged below the material distributing device (17), and the lower end of the upper screen feeding flowing plate (6) and the lower end of the lower screen feeding flowing plate (7) are located on an upper screen (8) and a lower screen (9) respectively; and a discharging belt conveyor (16) is arranged below the discharging end of the upper screen (8) and the discharging end of the lower screen (9). The grain winnowing vibration screen can effectively remove dust and all impurities such as light impurities, large impurities and small impurities in grain, and it is guaranteed that the impurity rate of the cleaned grain meets the storage requirement.

Description

technical field [0001] The invention relates to a vibrating screen for air selection of grain. Background technique [0002] Existing grain cleaning sieves include vibrating cleaning sieves or winnowing vibrating sieves. The structure of vibrating cleaning sieves generally includes a vibration generator and a sieve body, and the vibrator drives the sieve body to vibrate, thereby removing impurities. The winnowing vibrating screen is to add a set of fans on the basis of the vibrating cleaning screen to remove dust and small debris. Its weak point of existing these equipments is that effect is poor, and output is little, and environmental protection effect is poor. Contents of the invention [0003] The purpose of the present invention is to provide a vibrating screen for grain air separation with good impurity removal effect and high efficiency for the above-mentioned deficiencies in the prior art. [0004] The technical scheme that the present invention adopts is as foll...
