Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 As shown, the air-suction seed-fertilizer simultaneous seed and fertilizer application hole planter mainly consists of a retaining ring 1 (1), a seed inlet cover 2, a seed guide plate 3, a negative pressure seed suction plate 4, a bearing end cover 1 (5), a bearing 1 (6) with sealing rings at both ends, a negative pressure air intake shaft 7, a layered double-cavity duckbill 8, a turntable 9, a guide groove 10, a compression spring 11, a bearing 2 (12) with sealing rings at both ends, a bearing end cover 2 (13), a fertilizer inlet cover 14, and a retaining ring 2 (15). Among them, the negative pressure air intake shaft 7 is installed in the center hole of the turntable 9 in the order shown in the figure through the bearing 1 with sealing rings at both ends, the bearing 2 (12) with sealing rings at both ends, the bearing end cover 1 (5), and the bearing end cover 2 (13).

[0026] Reference Figure 2 , 3 As shown in Figure 4, the negative pressure seed suction plate 4 has 10 negative pressure seed suction holes 24 evenly opened. The outer edge boss and the center hole of the negative pressure seed suction plate 4 are designed with grooves for installing large sealing ring 16 and small sealing ring 17. One end of the negative pressure air intake shaft 7 has a negative pressure air intake port 18. Three negative pressure holes 20 and a keyway 19 for circumferential positioning are evenly opened on the shaft shoulder. The negative pressure seed suction plate 4, the bearing end cover 1 (5), and the bearing 1 (6) with sealing rings at both ends are installed on the seed-taking side of the turntable 9 by bolts. The negative pressure seed suction plate 4, the turntable 9 and the negative pressure air intake shaft 7 cooperate to form a negative pressure cavity.

[0027] Reference Figure 5 As shown, the seed inlet cover 2 has an observation window 27, a seed inlet 26 and a seed feeding hole 29, and a seed filling space baffle 25 and a seed cleaning plate 28 are welded below.

[0028] Reference Figure 6 As shown, the fertilizer inlet cover 14 has a fertilizer inlet hole 30 and a fertilizer dispensing hole 31.

[0029] Reference Figure 7 , 8 As shown, the bearing end cap 2 (13) is installed at the center hole on the fertilizer side of the turntable 9, and the fertilizer spoon 32 is evenly installed on the turntable 9, corresponding one-to-one with the guide groove 10.

[0030] The working process of the above-mentioned air-suction seed-mechanical fertilizer application hole-seeder is as follows:

[0031] S1: During operation, the negative pressure air intake shaft 7, seed inlet cover 2, and fertilizer inlet cover 14 do not rotate. The retaining ring 1 (1), seed guide plate 3, negative pressure seed suction plate 4, bearing end cover 1 (5), bearing end cover 2 (13), and retaining ring 2 (15) rotate synchronously with the turntable 9. When the turntable 9 rotates, a seed is adsorbed on the negative pressure seed suction hole 24 on the negative pressure seed suction plate 4 that is in contact with the seed, and there is a certain amount of fertilizer in the fertilizer scoop 32 filled with fertilizer.

[0032] S2: When the seeds and fertilizer are rotated to the seed inlet 29 and fertilizer inlet 31 under the influence of the negative pressure seed suction plate 4 and fertilizer spoon 32, the seeds enter the corresponding guide groove 10 through the seed inlet 29 under the action of the seed cleaning plate 28, centrifugal force and their own gravity. The fertilizer enters the corresponding guide groove 10 through the fertilizer inlet 31 under the action of centrifugal force and their own gravity. Then the seeds and fertilizer fall into the bottom of the seed cavity and fertilizer cavity of the layered double-cavity duckbill 8, respectively.

[0033] S3: When the layered double-cavity duckbill 8 is inserted into the soil, the moving duckbill 35 of the layered double-cavity duckbill 8 opens, and the fertilizer and seeds fall into different positions in the soil, completing one planting cycle. As the turntable 9 rotates, the duckbill 8 leaves the ground and closes under the action of the compression spring.

[0034] The above description only outlines the basic principles and preferred embodiments of this utility model. Those skilled in the art can make many changes and improvements based on the above description, and these changes and improvements should fall within the protection scope of this utility model.
