Description

Technical Field

[0001] This invention belongs to the field of precision seeder technology, specifically relating to an intelligent high-speed precision seeder depth limit wheel contouring depth adjustment mechanism. Background Technology

[0002] A precision seeder is a machine that sows seeds into the seedbed at precise rates, row spacing, and depth. It consists of components for precision seed metering, soil covering, and fertilization; some models can also monitor the seed metering process. Precision seeders come in mechanical and pneumatic types. The former has a simpler structure but is more demanding on seed size; the latter is more adaptable to different seed shapes and sizes, and precision seeding can save seeds and increase yield.

[0003] Currently, the two depth-limiting rollers on precision seeders can only perform contouring independently via a contouring mechanism. Because the ground surface is often uneven during sowing, independent contouring may result in uneven ridges. Therefore, in such cases, the contouring mechanism needs to allow both depth-limiting rollers to contour simultaneously to achieve a forced depth limit. If the sowing environment is even more complex, the contouring mechanism needs to allow both depth-limiting rollers to contour separately to achieve the appropriate sowing depth. Therefore, it is essential to develop and design a contouring mechanism that allows the two depth-limiting rollers to freely switch between independent and simultaneous contouring. Summary of the Invention

[0004] In order to solve the problem of unsatisfactory contouring effect of the depth limiting wheel in existing precision seeders, this invention provides an intelligent high-speed precision seeder depth limiting wheel contouring depth adjustment mechanism.

[0005] The technical solution adopted in this invention is:

[0006] The intelligent high-speed precision seeder's depth-limiting wheel contouring depth adjustment mechanism includes a depth-limiting wheel assembly, a contouring frame welding, a depth adjustment component, and two rockers. The front end of the contouring frame welding is mounted on the rear end of the seeding frame body of the seeding unit assembly. The rear ends of the two rockers are respectively rotatably mounted on the left and right sides of the middle of the contouring frame welding. The two depth-limiting wheels of the depth-limiting wheel assembly are respectively mounted on the front ends of the two rockers and move up and down through the rockers. The depth adjustment component is located above the two rockers and is installed in the middle position of the contouring frame welding, used to control the contouring depth of the depth-limiting wheel.

[0007] Compared with the prior art, the present invention has the following advantages:

[0008] This invention enables adjustment of the contouring depth and allows for switching between independent contouring by the two depth-limiting wheels and simultaneous contouring by both sides, resulting in better sowing performance of the individual sowing units. When the ground surface is uneven during sowing, the contouring mechanism allows both depth-limiting wheels to contour simultaneously, effectively limiting the depth and resulting in a smoother ridge after sowing. In more complex sowing environments, the contouring mechanism needs to allow the depth-limiting wheels to contour independently to achieve the appropriate sowing depth. Attached Figure Description

[0014] To better understand the purpose, structure, and function of this invention, the invention will be described in further detail below with reference to the accompanying drawings.

[0015] like Figures 1-4 As shown, the intelligent high-speed precision seeder's depth-limiting wheel contouring depth adjustment mechanism includes a depth-limiting wheel assembly 10, a contouring frame welded 1, a depth adjustment component, and two rockers 7. The front end of the contouring frame welded 1 is mounted on the rear end of the seeding frame body of the seeding unit assembly. The rear ends of the two rockers 7 are respectively rotatably mounted on the left and right sides of the middle of the contouring frame welded 1. The two depth-limiting wheels of the depth-limiting wheel assembly 10 are respectively mounted on the front ends of the two rockers 7 and move up and down through the rockers 7. The depth adjustment component is located above the two rockers 7 and is installed in the middle position of the contouring frame welded 1 to control the contouring depth of the depth-limiting wheel.

[0016] like Figures 1-4As shown, the depth adjustment assembly includes a contour adjustment plate 2, a contour stop 3, a fixed shaft 4, and a contour adjustment bolt 5. The upper middle part of the contour frame welding 1 has an installation gap 11. The vertical plate of the contour adjustment plate 2 is inserted into the installation gap 11. The contour adjustment plate 2 has an inverted T-shaped structure. The lower end of the vertical plate of the contour adjustment plate 2 has a round hole. A bearing 8 is installed in the round hole. The contour adjustment plate 2 is rotatably mounted on the main shaft 6 provided on the contour frame welding 1 via the bearing 8. A groove 21 is opened on the bottom surface of the middle protrusion of the contour adjustment plate 2. The fixed shaft 4 is installed in the groove 21. The upper end of the contour stop 3 is fitted onto the fixed shaft 4. The contour stop 3 spans across the two rocker arms 7. Both the contour stop 3 and the fixed shaft 4 have threaded through holes. The contour adjustment bolt 5 can detachably fix the contour stop 3 and the fixed shaft 4 through the threaded through holes.

[0017] Working principle: The depth-limiting wheel moves up and down following the contour of the ground, which in turn drives the rocker arm 7 to rotate, and then touches the contour stop block 3.

[0018] When the contouring adjustment bolt 5 is not installed, the contouring stop 3 and the fixed shaft 4 can rotate relative to each other. When encountering ground of different heights, the rocker arm 7, which rotates with the up and down movement of the depth limiting wheel, will touch the contouring stop 3. Because the contouring stop 3 can rotate, it will not force the two depth limiting wheels to the same height, thus achieving the purpose of contouring separately.

[0019] When the contouring adjustment bolt 5 is installed, the contouring stop 3 and the fixed shaft 4 are fixed relative to each other. The bottom surface of the contouring stop 3 is at the same height, which causes the two rockers 7 to rotate at the same angle. When the two rockers 7 contact the contouring stop 3, the two rockers 7 simultaneously drive the contouring stop 3 and the contouring adjustment plate 2 to rotate into the installation gap 11.

[0020] The rear ends of the two rocker arms 7 rotate to be mounted on the main shaft 6 of the profile frame welding 1.

[0021] like Figure 3 , Figure 4 As shown, the bearing 8 is an oil-free bearing.

[0022] like Figure 1 , Figure 2 As shown, the lower ends of both sides of the contour block 3 are provided with protrusions, and the contour block 3 contacts the rocker arm 7 through the protrusions.

[0023] like Figure 1 , Figure 2 As shown, a mud removal plate 9 is provided at the rear end of each depth limiting wheel, and both mud removal plates 9 are mounted on the main shaft 6.

[0024] It is understood that the present invention has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention.
