[0016] When working, the air inlet pipe 9 and the air inlet pipe 10 are connected to the fan, and the air flow enters the inner chamber through the air inlet 8 and the seed conveying port 13. Since the opening direction of the seed conveying port 13 arranged in multiple rows is opposite to the center line of the circular arc surface of the circular edge arc shell 4, and the opening direction of the seed conveying port 13 and the air inlet pipe 10 is inclined to the rotary channel inlet 2, the seed has a suspension force in the air suction type electric seed sowing disc suction port and the rotary channel inlet 2 in this interval. Under the action of the forward air flow entering from the air inlet 8, the seed moves along the center circular arc line direction of the air suction type electric seed sowing disc suction port. The air flow enters the rotary channel 1 from the rotary channel inlet 2, and the air flow is divided into two paths at the end of the vertical circular edge arc shell 4 section of the rotary channel 1. One path continues to send the seed to the rotary seed inlet 12 along the rotary channel 1 at a certain speed, and the seed reenters the seed inlet 11 before other seeds reenter the seed inlet 11. The other path enters the seed conveying air channel 5 through the mesh-shaped arc surface of the interface between the rotary channel 1 and the seed conveying air channel 5, and sends the seed captured by the seed conveying pipe outer edge 6 and the air conveying seed guide pipe 7 to the soil under the action of the seed conveying air channel 5.

Under the action of the air force, the seed that is not adsorbed enters the rotary channel 1 from the rotary channel inlet 2. The seed reenters the inner chamber from the seed inlet 11 after entering the rotary channel 1 from the rotary seed inlet 12 at the end of the seed tank guide pipe 3, and further completes the circular reciprocating motion.

The seed reenters the inner chamber from the seed inlet 11 after entering the rotary channel 1 from the rotary seed inlet 12 at the end of the seed tank guide pipe 3, and further completes the circular reciprocating motion.

[0019] When working, the air flow speed entering the air inlet pipe 9 and the air inlet pipe 10 is regulated by the control system, so that the suspension motion speed of the seed matches the linear speed of the seed sowing disc suction port.
