Problems solved by technology
In the practice of production operation, it was found that after the negative pressure of the air flow is cut off, the seeds are sorted by the weight of the seeds, and the phenomenon of seed jams that cannot be discharged often occurs, the rate of missed seeding increases, and the quality of seeding decreases. The number of phenomena will increase, and the rate of missed broadcasts is on the rise

The centrifugal needle air suction seed metering device belongs to agricultural machinery; the seed box is equipped with a drive shaft and a follower shaft, the driving sprockets A and B are fixed on the drive shaft, and the drive shaft is fixed on the drive shaft. Rotate the suit sprocket needle seat, chains A and B respectively connect the driving sprocket A to the sprocket drive sleeve and the driving sprocket B to the sprocket needle seat, the negative pressure air channel is set on the follower shaft, A plurality of seed suction needles are installed on the wheel-type needle base, and a flexible seed protection belt with a gap is arranged on the outer part of the circumference of the seed suction needle. The flexible seed protection belt is supported by belt rollers I, II, III, IV, and V , the belt roller I is the driving roller, and the gas nozzle and the seed guide tube are arranged at the gap of the flexible seed protection belt; Unload it to complete the seeding operation of the air suction seed metering device. It has the characteristics of reliable seeding, low seeding leakage rate, less operation failure, compact and reasonable structure.
Description
technical field [0001] The invention belongs to agricultural machinery, and mainly relates to an air suction seed metering device. Background technique [0002] Most of the current air-suction seed metering devices use negative pressure suction cups to complete the suction and discharge of seeds. This type of air-suction seed metering device not only has the defect of large structural size, especially in the seeding process of cutting off the negative pressure suction of the airflow, it can only rely on the self-weight of the seeds to remove the seeds adsorbed on the air holes of the negative pressure air plate from the sucker. discharge from the hole. In the practice of production operation, it is found that after the negative pressure of the air flow is cut off, the seeds are sorted by the weight of the seeds, and the phenomenon of seed jams that cannot be discharged often occurs, the rate of missed seeding increases, and the quality of seeding decreases. This phenomenon...
