Design and Experimental Study on Seed Metering Device of Peanut Plot Seeder

The seed metering device is the key working part of the peanut planter and is placed above the bottom of the seed box or above the opener. The essence of the seed metering process is the eff ect of the seed meter on the seed, converting the seed from the population into an individual, and converting it into a uniform seed stream or a continuous single seed. The seeding method and quality of the seeding machine depend mainly on the seed metering device. Aiming at the shortage of re-broadcasting rate and missed-out rate during sowing, the diff erent parameters of the air-suction metering device were analyzed, and the seeding performance of the seeding device was tested to obtain the primary and secondary factors aff ecting the performance of the seeding device, and the quality of seeding was improved.
