Abstract
The invention discloses a pneumatic double-layer roller type seed discharging device which comprises a transmission shaft, an inner roller, an outer roller, a ventilating disc, a seed box, an electromagnetic vibration exciter and a seed guide device. The inner roller is mounted on the transmission shaft, one end of the inner roller is in matched connection with the ventilating disc, and the outer roller is arranged on the inner roller in a sleeving mode and is in butt joint with the seed box in a matched mode. The seed box is connected with the electromagnetic vibration exciter through a connecting plate, and the seed guide device for receiving and guiding seeds is arranged at the lower end of the outer roller. A plurality of ventilating grooves are formed in the inner roller in the axial direction, and a plurality of air pressure holes communicated with the ventilating grooves are formed in the outer surface of the inner roller. The seeds located in a negative pressure area are adsorbed on shaped holes of the outer roller, and when the outer roller rotates to a positive pressure area with the seeds, the seeds are evenly spread out from the shaped holes under gravity and airflow blowing. The advantages of being simple in structure and high in operation efficiency, and reducing the probability of repeated sowing, miss-sowing ad seed damage are achieved.
