[0002] With the development of modern agricultural technology, improving agricultural production efficiency and quality has become one of the core goals of agricultural modernization. As a key link in agricultural production, the accuracy of sowing and fertilization directly affects the growth and final yield of crops. Traditional sowing and fertilization methods often rely on manual operation or simple mechanical devices, and there is a problem of inconsistent sowing depth, which not only affects the emergence rate and growth rate of crops, but also may cause fertilizer waste and environmental pollution. Summary of the invention

[0003] In view of the problems in the prior art, the present invention provides a high-precision seeding and fertilizing machine based on wheel position self-adjustment, and the specific technical scheme is as follows:

[0004] A high-precision seeding and fertilizing machine based on wheel position self-adjustment includes a frame, on which are mounted:

[0005] The rotating part includes two rotatably arranged transmission wheels and a transmission belt connected between the two transmission wheels, and a plurality of floating members are evenly arranged on the transmission belt along its track to form a closed linear matrix;

[0006] A wheel portion is arranged between the ground and the linear substrate, and when the wheel portion moves, a terrain path can be generated on the linear substrate based on the ground;

[0007] The feeding part includes a feeding pipe which can move vertically. The feeding part can read the terrain path to drive the feeding pipe to move vertically to adjust the sowing depth.

[0008] As a further technical solution of the present invention, the conveying speed of the linear substrate is the same as the traveling speed of the frame.

[0009] As a further technical solution of the present invention, the rotating part further includes a limit block arranged on the circulation path of the linear substrate, and the limit block has an inclined surface facing the linear substrate so that the generated terrain path is restored to the linear substrate.

[0010] As a further technical solution of the present invention, the wheel portion contacts the outer surface of the linear base, and the blanking portion contacts the inner surface of the linear base.

[0011] As a further technical solution of the present invention, the floating member includes a support plate, a slideway opened along the track of the support plate, a slider slidably arranged in the slideway, and a floating roller rotatably connected to the free end of the slider, and several groups of the floating rollers form a linear matrix.

[0012] As a further technical solution of the present invention, a base plate is installed on the frame, the wheel part is vertically arranged on the base plate and slidably connected thereto, the wheel part includes a bracket, a ground wheel and an extrusion roller, the bottom of the bracket is rotatably provided with a ground wheel that contacts the ground, and the top of the bracket is rotatably connected with an extrusion roller that contacts the linear base.

[0013] As a further technical solution of the present invention, the unloading part also includes a hopper, a feed pipe and an identification roller. The hopper and the feed pipe are both installed on a frame. The unloading pipe is slidably arranged under the feed pipe. The identification roller is rotatably arranged on the unloading pipe and contacts the linear substrate.

[0014] The beneficial effects of the present invention are as follows:

[0015] (1) In the present application, a linear matrix with circular motion is formed by setting a rotating part. When the transmission wheel rotates, the linear matrix can move in a circular motion to cooperate with the continuous movement of the seed drill. At the same time, the linear matrix will contact the squeezing roller and the identification roller in sequence during the circular motion. The squeezing roller is supported by the ground to feed back the terrain in real time on the linear matrix, thereby forming a terrain path generated based on the ground. When the subsequent identification roller contacts the linear matrix, the identification roller can identify the terrain path and make vertical movement to adjust the sowing depth, thereby ensuring that the depth of the feed tube inserted into the soil remains unchanged, that is, the sowing depth remains unchanged.

[0016] (2) In the present application, the movement speed of the linear substrate is made the same as the travel speed of the frame, thereby eliminating the distance difference between the two and ensuring the accuracy of the terrain path. BRIEF DESCRIPTION OF THE DRAWINGS

The feeding part 200 is used for sowing and fertilizing in the soil, and the wheel part 300 is used for measuring the terrain on the traveling path, and adjusting the sowing and fertilizing depth of the feeding part 200 accordingly; because the wheel part 300 is arranged in front of the feeding part 200 in the traveling direction, the wheel part 300 will observe the terrain of the path that the feeding part 200 will pass through before the feeding part 200, so as to adjust the sowing depth of the feeding part 200 in real time.

[0024] Continue to see Figure 2 The feeding part 200 includes a hopper 210, a feeding pipe 220 and a feeding pipe 230 which are arranged in sequence from top to bottom. The feeding pipe 230 is slidably connected to the feeding pipe 220 to adjust the sowing depth by moving up and down. The hopper 210 and the feeding pipe 220 are both installed on the frame 100 to form a whole with the frame 100 for stable feeding, and the feeding pipe 230 can move up and down relative to the whole to adjust the sowing depth. The seeds are stored in the hopper 210 and are sown quantitatively through the feeding pipe 220 and the feeding pipe 230 during walking.

A plurality of floating members 430 are evenly arranged on the transmission belt 420 along its track to form a closed linear matrix. When the wheel part 300 moves, it presses against the linear matrix and generates a terrain path. An identification roller 240 is rotatably arranged on the discharge tube 230. The identification roller 240 can identify the terrain path to drive the discharge tube 230 to move vertically to adjust the depth. The plurality of floating members 430 The shape path of the transmission belt 420 is closely arranged to form a closed linear matrix. When the transmission wheel 410 rotates, the linear matrix can circulate to cooperate with the continuous movement of the planter. At the same time, the linear matrix will contact the squeezing roller 340 and the identification roller 240 in sequence during the cyclic movement. The squeezing roller 340 is supported by the ground to feed back the terrain on the linear matrix in real time, thereby forming a terrain path generated based on the ground.
