Description

Technical Field

[0002] Grain sucker is a kind of material handling machinery, which can transport materials in all directions, such as paddy, rice, wheat, corn, sorghum, peanuts, plastic and granular materials, horizontally, inclined and vertically. Grain sucker is mainly composed of high-pressure fan, separation cylinder, air lock, connecting pipeline, suction nozzle and conveying pipe. Its working principle is that the negative pressure airflow generated by the high-pressure fan sucks the grain through the suction nozzle and hose, and the air and materials are separated through the elbow and separation cylinder. The materials rotate and fall down to the air lock, and then to the outlet of the fan, and are pressed to the required place by the positive pressure airflow through the conveying pipeline.
