Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Figure 1-Figure 5 As shown together, the air-assisted precision seed and fertilizer co-seeding device includes a seed and fertilizer box 1, a fertilizer box 2 and a seed box 3 are installed at the bottom of the seed and fertilizer box 1, the fertilizer box 2 is connected to a fertilizer distributor 5 through a fertilizer guide pipe 4, the seed box 3 is connected to a seed distributor 7 through a seed guide pipe 6, and the fertilizer guide pipe 4 and the seed guide pipe 6 are commonly connected to an air-assisted source.

[0028] Among them, a hanging frame 8 is arranged on the rear side of the seed and fertilizer box 1, and several groups of seed and fertilizer co-seeding components are installed on the hanging frame 8, each of which includes a fertilizer opener 9 and two sowing openers 10, and the fertilizer opener 9 is arranged between the two sowing openers 10, each fertilizer opener 9 is connected to the fertilizer distributor 5 through a lower fertilizer pipe 11, and each sowing opener 10 is connected to the seed distributor 7 through a lower seed pipe 12.

[0029] In the present invention, the air blowing assist source is used to provide assistance for the transportation of fertilizers and seeds. The fertilizers and seeds discharged from the fertilizer box 1 are quickly transported under the action of the airflow, and are evenly distributed by the fertilizer distributor 5 and the seed distributor 7, so that the fertilizer is evenly distributed to each fertilizer opener 9, and the seeds are evenly distributed to each sowing opener 10, thereby realizing precise fertilization and sowing operations on the land; and compared with the structure that relies on gravity to plant and fertilize, the present invention adds an air blowing assist structure, which speeds up the transportation speed of fertilizers and seeds, thereby improving the fertilization and sowing efficiency of the present invention.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown in common, the air blowing assist source includes an air blowing machine 13 fixed on the seed and fertilizer box 1, and an air blowing main pipe 14 is fixedly installed on the front wall of the seed and fertilizer box 1. The air blowing main pipe 14 is connected with the air outlet of the air blowing machine 13, and the air blowing main pipe 14 extends along the length direction of the seed and fertilizer box 1. Two air blowing branch pipes 15 are installed on the air blowing main pipe 14, one of the air blowing branch pipes 15 is connected with the fertilizer guide pipe 4, and the other air blowing branch pipe 15 is connected with the seed guide pipe 6.

[0031] like Figure 3 and Figure 4 As shown together, a connecting piece 16 is fixed to the bottom of the fertilizer box 2 and the seed box 3, wherein one air blowing branch pipe 15 and the fertilizer box 2 are connected to the feed end of the fertilizer guide pipe 4 through the connecting piece 16, and the other air blowing branch pipe 15 and the seed box 3 are connected to the feed end of the seed guide pipe 6 through the connecting piece 16.

[0032] like Figure 1 and Figure 2 As shown together, the fertilizer distributor 5 is installed on a fertilizer guide riser 17, the seed distributor 7 is installed on a seed guide riser 18, the fertilizer guide riser 17 and the seed guide riser 18 are both fixed on the suspension frame 8, the lower end of the fertilizer guide riser 17 is connected to the fertilizer guide pipe 4, the fertilizer distributor 5 is installed on the upper end of the fertilizer guide riser 17, the lower end of the seed guide riser 18 is connected to the seed guide pipe 6, and the seed distributor 7 is installed on the upper end of the seed guide riser 18.

[0033] Moreover, the length of the seed guide riser 18 is greater than that of the fertilizer guide riser 17.

Because every two sowing furrow openers 10 correspond to one fertilization furrow opener 9, the number of seed tubes 12 connected to the seed guide riser 18 is relatively large. Therefore, the higher height not only facilitates the arrangement of the seed tubes 12, but also reduces the bending angle of the seed tubes 12, making the seed placement smoother.

A pair of columns 20 are fixedly installed on the crossbeam 19. A vertical plate 21 is fixed on the two side walls of the seed fertilizer box 1, and the position of the vertical plate 21 corresponds to the position of the column 20. The lower end of each column 20 and the lower end of the vertical plate 21 are hingedly connected with a connecting arm 22. A swing arm 23 is arranged above each connecting arm 22. One end of each swing arm 23 is hingedly installed on the corresponding vertical plate 21, and the other end of each swing arm 23 is installed with a screw rod 24. A hinge shaft 25 is hingedly installed on each column 20, and each screw rod 24 passes through the corresponding hinge shaft 25. A limiting nut 26 is arranged on both sides of each hinge shaft 25. Each limiting nut 26 is pressed on the side wall of the hinge shaft 25, and each limiting nut 26 is threadedly installed on the corresponding screw rod 24.

[0035] In the utility model, the user can adjust the height of the suspension frame 8 by adjusting the positions of the two limit nuts 26 on the screw rod 24, thereby driving the swing arm 23 and the connecting arm 22 to rotate. The adjustment of the height of the suspension frame 8 can adjust the soil penetration depth of the sowing furrow opener 10 and the fertilizing furrow opener 9, thereby making the utility model suitable for seed and fertilizer sowing operations in different land environments.

[0036] In addition, a covering wheel 27 is disposed at the rear side of each sowing furrow opener 10 , and each covering wheel 27 is installed together with the corresponding sowing furrow opener 10 .

[0037] In summary, the air-blowing-assisted precision seeding and fertilizer co-seeding device proposed in the utility model adds an air-blowing-assisted structure, which realizes the rapid and precise dropping of fertilizers and seeds, and improves the efficiency of sowing and fertilizing.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
