The input end of the reduction motor 5 is electrically connected to the output end of an external power supply. The reduction motor 5 is placed on the outer side of the first seed-rowing half shell 1, which is convenient for the installation and use of the reduction motor 5, and the power output end of the reduction motor 5 is connected to a driving gear 6;

[0027] A second seeding half shell 7 is fixedly installed on one side of the first seeding half shell 1 by bolts, an axle seat 8 is embedded in the middle of the second seeding half shell 7, a seeding disk 9 is rotatably sleeved on the outside of the axle seat 8, an inner gear ring 10 is installed on the inner side of the seeding disk 9, a driving gear 6 is placed on the inner side of the first seeding half shell 1, and the seeding disk 9 is placed on the inner side of the second seeding half shell 7, the driving gear 6 is meshed and connected with the inner gear ring 10, so as to drive the seeding disk 9 to rotate conveniently, a recessed groove 11 is stamped on the edge of the seeding disk 9, an air suction hole 12 is opened at the position of the recessed groove 11 on the edge of the seeding disk 9, a plurality of air suction holes 12 and recessed grooves 11 are provided, and the air suction holes 12 are opened at The edge of the seeding plate 9 corresponds to the position between adjacent concave grooves 11, so that the air suction holes 12 are evenly distributed, so that the seeding is uniform. A plurality of air holes 13 are provided on the outer side of the second seeding half shell 7 near the air suction holes 12. An air pipe seat 14 is installed on the outer side of the second seeding half shell 7. The air pipe seat 14 is a three-quarter circular structure. The air holes 13 are provided on the outer side of the second seeding half shell 7 at the position corresponding to the air pipe seat 14, so as to facilitate the suction of seeds. An air supply pipe 15 is fixedly installed on the outside of the air pipe seat 14 by bolts. A negative pressure connecting pipe 16 is embedded and installed at the bottom of the air supply pipe 15. One end of the negative pressure connecting pipe 16 is connected to a negative pressure fan to form a negative pressure to suck up seeds.

[0028] The bottom of the first seed row half shell 1 is connected with a guide tube 17, the top of the air pipe 15 is sealed, the guide tube 17 is installed at the bottom of the first seed row half shell 1 away from the air pipe 15, the bottom of the conveying channel 3 is laterally aligned with the bottom of the air pipe 15 to facilitate air flow inhalation, and the bottom end of the guide tube 17 is connected with a seed row tube 18.
