Abstract

The invention relates to an air-suction seed-metering device for seeding in a community. The seed-metering device comprises a seed-metering device shell, a guide groove plate fixing device, a drivingplate, a guide groove plate, an air suction plate, a forced discharge plate and a seed storage shell; the seed storage shell and the seed-metering device shell are connected to form an inside closed space; the seed-metering device shell is provided with an air suction port; the forced discharge plate, the air suction plate, the guide groove plate, the guide groove plate fixing device, the drivingplate and a rolling bearing are arranged between the seed storage shell and the seed-metering device shell in sequence. In the seed-metering device, discharge guide groove holes are designed for different seeds, each discharge guide groove hole can suck only one seed, the plant distance uniformity is guranateed, and re-seeding and miss-seeding are avoided; meanwhile, under the action of positive pressure and negative pressure, seed clearing is thorough, no seed remains, and no seed is damaged.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an air-suction type plot sowing and metering device. Background technique [0002] With the breeding industry's higher requirements for breeding technology and breeding equipment, the existing breeding machinery is complicated to operate, the precision of the seed metering device is not high, the cleaning of seeds is not thorough, and the problem of seed damage during cleaning is serious. Most of the seed metering devices now use mechanical seeding, which is easy to cause damage to the seeds, and the seeding accuracy is not high. The existing pneumatic seed metering device is mainly used for field sowing, and there is a lack of a seed metering device for clearing and frequent seeding when sowing in plots. The invention adopts an air-suction seed metering device, which can meet the needs of seeds with different particle sizes, and is convenient and efficient for seed cleaning. Content...
