Grain winnowing device with floating shedding plate

Abstract

The invention discloses a grain winnowing device with a floating shedding plate. The grain winnowing device with the floating shedding plate comprises a feed cylinder, and the shedding plate and an air-intake box which are positioned below the feed cylinder in sequence, a winnowing box is arranged in the side direction of the feed cylinder, the air-intake box is communicated with the winnowing box, a feed port is formed in a side wall of the winnowing box, the end part of the shedding plate is opposite to the feed port, the grain winnowing device is characterized in that a mounting seat is arranged inside the air-intake box, the upper part of the mounting seat is hinged to an air-intake adjusting plate, the air-intake adjusting plate is positioned at the communicating part of the air-intake box and the winnowing box, an air-intake hole is formed in the air-intake adjusting plate, the upper end of the air-intake adjusting plate is hinged to a rotating shaft, one side, close to the winnowing box, of the shedding plate is hinged to the rotating shaft, the upper part of the side, close to the winnowing box, of the shedding plate is fixed together with the lower end of a tension spring, the upper end of the tension spring is fixed on a mounting rod, the mounting rod comprises a vertical rod and a cross rod, a mounting plate is arranged in the lateral direction of the winnowing box, a strip-type groove is formed in the mounting plate, a plurality of clamping grooves are formed in the side wall of the strip-type groove, and the cross rod is positioned in the strip-type groove and can be clamped in the clamping grooves.

Description

technical field The invention relates to a grain air separation technology, in particular to a grain air separation device with a floating drip plate. Background technique According to the difference in the aerodynamic properties of grain and impurities, the method of separating by air flow is called winnowing. Wind separation equipment used for grain cleaning is divided into external suction type and circulation type according to the treatment method of dusty air, blowing type and suction type according to gas pressure, and vertical type and horizontal type according to the direction of airflow movement. There is an existing vertical suction air separation device, its main structure includes a feeding cylinder, an inclined dripping plate located below the feeding barrel, a motor that drives the vibration of the dripping plate, and an air separation channel located on the side of the feeding hopper. When working, The vibrating motor drives the dripping plate to vibrate in t...

AI Technical Summary

Problems solved by technology

The problems that exist in the above-mentioned vertical suction winnowing device are: 1. The adjustment of the air volume entering the winnowing channel is realized by an additional regulating valve (such as a butterfly valve), which has a complex structure and high cost; 2. The inclination of the dripping plate The angle cannot be adjusted, and it is impossible to adjust the amount of material entering the wind separation channel according to the wind separation requirements of different materials
