[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 An intelligent no-till precision corn planter with adjustable depth includes a frame section 10, a seed section 20, at least one set of seeding sections 30, a body connecting section 40, and several sets of rotary tillage sections 50. The seed section 20 is mounted and fixed to the top of the frame section 10 and is used to hold corn seeds. At least one set of seeding sections 30 is installed below and communicates with the seed section 20, and is used to dispense corn seeds for sowing. Several sets of rotary tillage sections 50 are installed below the frame section 10 and are used for furrowing the ground. The body connecting section 40 connects the body and the frame section 10.

[0023] In this embodiment, the frame section 10 can adopt an existing structure in the prior art, with a vehicle mounted on its side to assist the movement of the device, and a transmission structure can also be provided on its side to cooperate in driving the seed material section 20.

[0024] In this embodiment, the seed section 20 includes a feed hopper 21, at least one spiral feed roller 22, and multiple discharge ports 23. The top of the feed hopper 21 has an opening, and a cover plate is hinged to the opening to close it. Corn seeds can be placed in the feed hopper 21. At least one spiral feed roller 22 is rotatably mounted in the inner cavity of the feed hopper 21 by a motor drive, allowing it to agitate the corn seeds. Multiple discharge ports 23 are formed on the sides of the feed hopper 21 and extend through it, allowing the corn seeds to be agitated and discharged from the discharge ports 23.

[0025] In this embodiment, the sowing section 30 includes a shaft 31, a number of connecting seats 32 equal to the number of discharge ports 23, a rotating seat 33, and a guide tube 34. The shaft 31 is fixedly mounted on the frame section 10. Several connecting seats 32 are spaced apart and mounted on the shaft 31, with the upper end of each connecting seat 32 communicating with the discharge port 23, allowing corn seeds to fall into the connecting seat 32. Each connecting seat 32 has a rotating seat 33 rotatably connected to its inner cavity. The outer side of the rotating seat 33 has multiple grooves, and the length of the rotating seat 33 is adapted to the width of the inner cavity of the connecting seat 32. After the corn seeds accumulate in the grooves, gravity causes the rotating seat 33 to deflect, causing the corn seeds in the corresponding grooves to fall downwards. The lower end of the connecting seat 32 is connected to the upper end of the guide tube 34, and the lower end of the guide tube 34 has an opening that allows a fixed quantity of corn seeds to be intermittently discharged for sowing.

[0026] In this embodiment, the vehicle body connecting part 40 includes a connecting frame 41, a hydraulic push rod 42, a deflection frame 43, and a double connecting frame 44. The front end of the connecting frame 41 is connected to the rear end of the vehicle body. The bottom end of the hydraulic push rod 42 is rotatably connected to the connecting frame 41. The output end of the hydraulic push rod 42 is rotatably connected to the top of the double connecting frame 44. The front end of the deflection frame 43 is rotatably connected to the side of the connecting frame 41. The rear end of the deflection frame 43 and the bottom end of the double connecting frame 44 are both bolted to the frame part 10. The extension and retraction of the output end of the hydraulic push rod 42 can adjust the position of the frame part 10 using the deflection frame 43 and the double connecting frame 44.

[0027] In this embodiment, the rotary tillage unit 50 includes several rotating blades 51, fixed blades 52, soil-pulling rods 53, and elastic supports 54. The elastic supports 54 are installed below the frame unit 10, and each elastic support 54 has a rotating blade 51 rotatably connected to its lower end. Each fixed blade 52 is fixed to the lower end of an adjacent feed pipe 34. The rotating blades 51 and fixed blades 52 are used to create trenches on the ground when the equipment moves. Each soil-pulling rod 53 is fixedly connected to an adjacent elastic support 54, and the lower end of each soil-pulling rod 53 extends behind the adjacent rotating blades 51 and fixed blades 52. During equipment movement, corn seeds can fall into the trenches created by the equipment, and then the soil-pulling rods 53 can push soil particles to bury the seeds.

[0028] In this embodiment, the elastic support 54 includes a vertical movable frame 541, two parallel connecting rods 542, a spring 543, and a spring-loaded lifting rod 544. The two parallel connecting rods 542 are rotatably connected to the frame portion 10, and the vertical movable frame 541 is rotatably connected to both parallel connecting rods 542. The spring-loaded lifting rod 544 is fixedly mounted on one of the parallel connecting rods 542. One end of the spring 543 is connected to the parallel connecting rod 542, and the other end of the spring 543 is connected to the frame portion 10. By utilizing the cooperation between the vertical movable frame 541 and the two parallel connecting rods 542, the rotating blade 51 mounted at the bottom of the vertical movable frame 541 can be adjusted in position according to the unevenness of the road surface. Furthermore, the elastic deformation of the spring 543 ensures that the rotating blade 51 remains in contact with the ground.

[0029] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
