The invention provides a precision
seeder capable of realizing the synchronous transmission of conveying and a rotary drum. The precision
seeder comprises a rack, wherein a hole pressing part, a seed clearing part, a seed storage vibration part and a seeding part which are connected to one another through a transmission mechanism are arranged on the rack, a
seedling growing tray is arranged on the transmission mechanism, the hole pressing part comprises a hole pressing shaft arranged on the rack, hole pressing wheels are arranged on the hole pressing shaft, hole pressing lugs on the hole pressing wheels are in contact with the
seedling growing tray, the seed clearing part comprises a seed clearing and air blowing
pipe arranged on the rack, a seed clearing and air blowing
nozzle is arranged on the seed clearing and air blowing
pipe, the seed storage vibration part comprises a seed storage groove and a seeding vibrator which is arranged on the rack, the seed storage groove is formed in the rack, the seeding part comprises a seeding shaft arranged on the rack, the seeding rotary drum is arranged on the seeding shaft, a seeding hole is formed in the seeding rotary drum, the transmission mechanism comprises a conveyer belt arranged on the rack, and the conveyer belt and the seeding shaft are driven by the synchronous transmission mechanism. The precision
seeder is small in size, high in seeding precision, and convenient to install and debug, saves the cost, realizes the synchronous transmission of conveying and seeding and has the good conveying and seeding coordination property.
