Precision seed planer structure and principle?
First, the suction suction precision two, the mechanical precision of the amount of suction suction is mainly driven by the tractor after the drive, driven by the suction fan and then, by the mouth of the device on the sucker, suction, seed.
(Apply: corn, sunflower, cotton, playing melon) mechanical mainly by the mouth of the device on the size of the next device to the amount of precision, only for single, the size of the more uniform seed (cotton)
