the tractor respectively transmits power to the swinging vibration driving unit and the conveying seed sowing unit through a gearbox chain wheel, a driving shaft 7 of the swinging vibration driving unit drives a swinging eccentric wheel 9 and a vibration eccentric wheel 32 to rotate, and when the swinging eccentric wheel 9 and the vibration eccentric wheel 32 rotate, the swinging connecting disc 10 and the vibration connecting disc 35 both do reciprocating swinging back and forth along the direction vertical to the axis of the driving shaft 7, so that the swinging plate 15 is driven to swing back and forth and the vibration plate 23 is driven to perform composite vibration in the up-down and back-forth directions.
The miniature potato seeds fall onto the vibrating plate 23 and the conveying belt 26 from the seed falling port of the seed box 1, the conveying belt 26 conveys the miniature potato seeds in the advancing direction of the seeder, single-row sequencing of the miniature potato seed groups on the conveying belt 26 is realized under the forward and backward swinging action of the swinging plate 15 and the combined limiting action of the swinging plate 15 and the seed protecting bulge 40 on the right side edge of the outer surface of the conveying belt 26, redundant and unsorted miniature potato seeds on the conveying belt 26 cross the seed protecting bulge 40 arranged on the right side edge of the outer surface of the conveying belt 26 and move onto the vibrating plate 23, the miniature potato seeds on the vibrating plate 23 return to the corresponding position of the seed falling port of the seed box 1 under the reciprocating vibration action of the vibrating plate 23 and enter the conveying belt 26 again for single-row sequencing, and the miniature potato seeds in single-row sequencing move to the clapboard 34 under the conveying action of the conveying belt 26, The rear part of the left guard plate 4, the upper belt of the inclined section of the conveying belt 26 and the lower belt of the pressure belt 29 form a seed falling channel together. At the moment, the seed pressing belt 29 with the same rotating speed as the conveying belt 26 presses and positions the miniature potato seeds, and the miniature potato seeds are conveyed to the seed discharging port of the seed discharging frame under the combined action of the conveying belt 26 and the seed pressing belt 29 and finally thrown into the seed ditch formed by the ditching unit 2.
