Description

Technical Field

[0001] This invention relates to the field of seeding and fertilizing machine technology, specifically a high-precision seeding and fertilizing machine based on wheel position self-adjustment. Background Technology

[0002] With the development of modern agricultural technology, improving agricultural production efficiency and quality has become one of the core goals of agricultural modernization. Sowing and fertilization, as crucial links in agricultural production, directly affect crop growth and final yield. Traditional sowing and fertilization methods often rely on manual operation or simple mechanical devices, resulting in inconsistent sowing depths. This not only affects crop emergence rate and growth speed but may also lead to fertilizer waste and environmental pollution. Summary of the Invention

[0003] This invention addresses the problems in existing technologies by providing a high-precision seeding and fertilizing machine based on wheel position self-adjustment. The specific technical solution 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 rotating drive wheels and a drive belt connected between the two drive wheels. A number of floating elements are evenly distributed along the track of the drive belt to form a closed linear base.

[0006] The wheel section is positioned between the ground and the linear substrate, and when the wheel section moves, it can generate a terrain path on the linear substrate based on the ground.

[0007] The feeding section includes a vertically movable feeding pipe, which 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 matrix 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 limiting block arranged on the linear base circulation path, the limiting block having an inclined surface facing the linear base, so that the generated terrain path is restored to the linear base.

[0010] As a further technical solution of the present invention, the wheel part contacts the outer surface of the linear matrix, and the feeding part contacts the inner surface of the linear matrix.

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

[0012] As a further technical solution of the present invention, a base plate is installed on the frame, and the wheel is vertically arranged on the base plate and slidably connected thereto. The wheel 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 substrate.

[0013] As a further technical solution of the present invention, the feeding part further includes a hopper, a conveying pipe and an identification roller. The hopper and the conveying pipe are both mounted on the frame. The feeding pipe is slidably arranged below the conveying pipe. The identification roller is rotatably arranged on the feeding pipe and contacts the linear substrate.

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

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

[0016] (2) In this application, the movement speed of the linear base is 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. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] Figure 1 A schematic diagram of a high-precision seeder and fertilizer applicator based on wheel position self-adjustment is shown. Figure 2 A schematic diagram of the internal structure of a high-precision seeder and fertilizer applicator based on wheel position self-adjustment is shown. Figure 1 and Figure 2 The high-precision seeder and fertilizer based on wheel self-adjustment includes a frame 100, on which a feeding section 200 and a wheel section 300 are arranged sequentially along the direction of travel. The feeding section 200 is used to sow and fertilize the soil, and the wheel section 300 is used to measure the terrain on the travel path and adjust the sowing and fertilization depth of the feeding section 200 accordingly. Since the wheel section 300 is located in front of the feeding section 200 in the direction of travel, the wheel section 300 will observe the terrain of the path that the feeding section 200 will pass through before the feeding section 200, so as to adjust the sowing depth of the feeding section 200 in real time.

[0024] See also Figure 2 The feeding section 200 includes a hopper 210, a conveying pipe 220, and a feeding pipe 230 arranged sequentially from top to bottom. The feeding pipe 230 is slidably connected to the conveying pipe 220, and the sowing depth is adjusted by moving up and down. The hopper 210 and the conveying pipe 220 are both mounted on the frame 100 and form an integral part with the frame 100 for stable feeding. The feeding pipe 230 can move up and down relative to the integral part to adjust the sowing depth. The seeds are stored in the hopper 210 and are sown quantitatively through the conveying pipe 220 and the feeding pipe 230 during movement.

[0025] See also Figure 2The wheel section 300 includes a vertically movable support 320. A ground wheel 330 is rotatably mounted at the bottom of the support 320, and a pressing roller 340 is rotatably connected to the top of the support 320. A base plate 310 is mounted on the frame 100, and the base plate 310 is slidably connected to the wheel section 300. That is, the wheel section 300 is slidably connected to the frame 100 via the base plate 310 to move vertically. The base plate 310 is a mounting component that supports the wheel section 300 and is connected to the frame 100. The support 320, the ground wheel 330, and the pressing roller 340 are an integral structure that can move vertically relative to the base plate 310. The ground wheel 330 contacts the soil and travels along its surface, and can drive the support 320, the ground wheel 330, and the pressing roller 340 to move vertically as a whole according to the terrain.

[0026] Figure 3 A schematic diagram of the rotating part 400 is shown; Figure 3In the process, the rotating part 400 is mounted on the frame 100 and includes two rotatably mounted drive wheels 410 and a drive belt 420 connected between the two drive wheels 410. A plurality of floating elements 430 are evenly distributed along the track of the drive belt 420 to form a closed linear base. When the wheel part 300 moves, it presses against this linear base and generates a terrain path. A recognition roller 240 is rotatably mounted on the feed pipe 230. The recognition roller 240 can recognize the terrain path to drive the feed pipe 230 to move vertically to adjust the depth; the plurality of floating elements 430... A closed linear substrate is formed by closely arranged elements along the shape path of the drive belt 420. This linear substrate can circulate when the drive wheel 410 rotates, thus coordinating with the continuous movement of the seeder. During this circulatory motion, the linear substrate sequentially contacts the squeezing roller 340 and the recognition roller 240. The squeezing roller 340, supported by the ground, reflects the terrain onto the linear substrate in real time, thus forming a terrain path generated based on the ground. When the recognition roller 240 subsequently contacts the linear substrate, it can identify the terrain path and use it for vertical orientation. The movement of the linear substrate adjusts the sowing depth, ensuring that the depth of the feed pipe 230 inserted into the soil remains constant, i.e., the sowing depth remains constant; the conveying speed of the linear substrate is the same as the traveling speed of the frame 100; that is, when the extrusion roller 340 contacts the linear substrate, it marks a corresponding mark on the ground, and when the recognition roller 240 reads the mark, it moves accordingly to the location of the ground, eliminating the distance difference between the two and ensuring the accuracy of the terrain path; the rotating part 400 also includes a limiter set on the circulation path of the linear substrate. Block 440, the limiting block 440 has an inclined surface facing the linear substrate so that the generated terrain path will be restored to the linear substrate; the limiting block 440 is mounted on the frame 100, which enables the linear substrate to be used repeatedly and realizes automatic circulation; the extrusion roller 340 contacts the outer surface of the linear substrate, and the recognition roller 240 contacts the inner surface of the linear substrate; the extrusion roller 340 is supported by the ground and can apply an upward pressure to generate the terrain path, while the recognition roller 240 falls freely and is supported by the linear substrate and can move up and down to recognize the terrain path.

[0027] Figure 4 A structural schematic diagram of the floating component 430 is shown; Figure 4In this structure, the floating component 430 includes a support plate 431, a slide rail 432 extending along the trajectory of the support plate 431, a slider 433 slidably disposed within the slide rail 432, and a floating roller 434 rotatably connected to the free end of the slider 433. Several sets of floating rollers 434 form a linear base. Several sets of floating rollers 434 are closely arranged to form a linear base, and the floating rollers 434 can slide relative to the support plate 431 to satisfy the undulation of the linear base. The slider 433 and the slide rail 432 are connected by a damped sliding connection. That is to say, when the floating roller 434 moves to a certain position, it will stop at the current position, thereby generating a terrain path. The floating roller 434, the squeezing roller 340, and the identification roller 240 are all rotatably disposed, which can reduce the resistance when they come into contact with each other and change sliding into rolling.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
