Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a hydraulic contouring and independent suspension frame assembly for a no-till planter. Background Technology

[0002] No-till planters, as key equipment for promoting green and sustainable agricultural development, are core agricultural machinery in the conservation tillage technology system. In the current context of agriculture pursuing cost reduction, efficiency improvement, and reduced ecological damage, they can complete a series of operations—ditching, sowing, fertilizing, and covering—in one continuous operation without prior land preparation. This not only reduces mechanical disturbance during soil cultivation, lowering the risk of soil structure damage, but also effectively suppresses farmland dust and soil erosion, protecting the farmland ecosystem. Furthermore, compared to traditional segmented sowing operations, their integrated operation mode significantly shortens the sowing cycle, substantially improves sowing efficiency, and can flexibly adapt to the large-scale planting needs of various crops such as wheat, corn, and soybeans, providing strong support for modern large-scale and intensive agricultural production.

[0003] With the adjustment of agricultural planting structure and the advancement of high-standard farmland construction, the application scenarios of no-till seeding technology are constantly expanding, gradually extending from flat plots to complex plots such as hilly areas and sloping farmland. These uncultivated plots often have problems such as uneven surface, large differences in soil hardness, and a lot of stubble and weeds, which puts forward higher requirements for the operational adaptability and precision of no-till seeders. In particular, the frame, as the "skeleton" of the whole machine, directly determines the seeding quality and operational stability through its conformity and control performance.

[0004] High-precision no-till planters need to operate on complex and uneven uncultivated land, which places high demands on the contouring function and control capabilities of the frame. However, traditional planter frames are mostly rigid integral structures or only have simple integral contouring functions, resulting in poor stability of the whole machine on transverse slopes, leading to inconsistent sowing depth on both sides. They cannot absorb small protrusions or depressions encountered by individual seed units, causing individual seed units to bounce and affecting local sowing depth. The pressure of the press roller on the ground cannot be adjusted and is unstable, resulting in uneven compaction on undulating ground. To address these issues, a hydraulic contouring and independent suspension frame assembly for no-till planters is proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a hydraulic contouring and independent suspension frame assembly for no-till seeders, which solves the problems of poor lateral slope stability, uneven sowing depth, and poor compaction effect that are common in traditional seeders due to limitations in frame structure and contouring function.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic contouring and independent suspension frame assembly for a no-till planter, comprising: Two first crossbeams and several second crossbeams, with the several second crossbeams arranged in three columns from front to back; The hydraulic linkage contour-following column platform is set on the surface of the first and second crossbeams. It is used to adapt the whole machine platform to the macro terrain by adapting to the left and right undulations of the terrain, while suppressing the lateral tilt of the seeder. The hydraulic linkage contouring column platform includes several contouring floating frames, a tool stabilizing mechanism, several contouring frame front connecting rods, and several tool fixing frames. Several of the tool fixing frames are arranged on the surfaces of two first crossbeams. The tool stabilizing mechanism is arranged on the surface of the first crossbeams. One end of the contouring frame front connecting rod is connected to the tool fixing frame, and the other end of the contouring frame front connecting rod is connected to the second crossbeam. A contouring floating frame is arranged between two adjacent rows of two second crossbeams. An independent elastic suspension mechanism is installed on the surface of the contoured floating frame to provide each seeding unit with independent degrees of freedom of movement, while protecting the core components when the seeding unit encounters obstacles; The compaction pressure control mechanism, located on the surface of the second crossbeam at the rear, is used to regulate the terminal pressure, providing a continuously adjustable downward pressure to the compaction wheel and ensuring a constant compaction force on the soil.

[0016] This invention provides a hydraulic contouring and independent suspension frame assembly for a no-till planter. It offers the following advantages: 1. The no-till seeder of this invention has excellent sowing depth consistency in its frame assembly: thanks to the dual mechanism of macro-hydraulic contouring and micro-elastic contouring, the macro-hydraulic linkage main platform adapts to terrain undulations and suppresses lateral tilting, while the micro-independent elastic suspension allows each sowing unit to float with slight undulations. Moreover, the weight of seeds and fertilizers is borne by the tractor and does not interfere with the sowing components. Even in extremely irregular terrain conditions, the sowing depth of each row can be highly consistent.

[0017] 2. The frame assembly of the no-till seeder of this invention makes the whole machine more stable during operation. The hydraulic interconnected main platform has excellent stability. The closed hydraulic circuit generates anti-torsional resistance, which effectively suppresses lateral tilting. The independent frame is connected to the main frame through the hydraulic cylinder through the elastic joint, which is not affected by unrelated mass. The traveling direction is stable and the posture can be flexibly adjusted. The whole machine operates smoothly and has better traction effect.

[0018] 3. The frame assembly of the no-till seeder of this invention has a controllable compaction effect. The compaction wheel pressure control mechanism is independent of the main contour hydraulic circuit and is controlled by the tractor hydraulic system alone. It can provide continuous and adjustable downward pressure, and the pressure is not affected by terrain undulations. Users can adjust it according to soil moisture and properties to ensure constant compaction pressure and achieve better seedbed preparation.

[0019] 4. The frame assembly of the no-till seeder of this invention has a high degree of integration, integrating macro-shaping, micro-shaping, and compaction control functions into the frame assembly to form a high-quality chassis. The main frame and independent frames are separated, and the independent frames are free from unrelated mass constraints. Each frame is connected to only one seeding unit and does not interfere with each other. It can also be adapted to different soils through a pressure reducing valve, taking into account both integration and flexibility. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides a hydraulic contouring and independent suspension frame assembly for a no-till planter, comprising: Two first crossbeams 17 and several second crossbeams 18 are arranged in three columns from front to back. The spacing between adjacent second crossbeams 18 is designed according to the number of sowing units and the crop row spacing requirements to ensure that the operation of each sowing unit does not interfere with each other. The crossbeams provide an installation frame for other structures on the frame assembly for construction. The hydraulic linkage contouring column platform is set on the surface of the first crossbeam 17 and the second crossbeam 18 to achieve macroscopic contouring and stabilization of the whole machine. By adapting to the left and right undulations of the terrain, the whole machine platform can conform to the macroscopic terrain, such as transverse slopes, gentle hills and other plots. At the same time, it suppresses the lateral tilt of the seeder and improves the stability during operation and transportation. Even when passing through bumpy sections during transportation, it can reduce the shaking of the machine body and protect the components from damage. The hydraulic linkage contouring column platform includes several contouring floating frames 8, a tool stabilizing mechanism 14, several contouring frame front connecting rods 15, and several tool fixing frames 16. The tool fixing frames 16 are set on the surfaces of the two first crossbeams 17, providing a stable connection base for the contouring frame front connecting rods 15 and ensuring the structural stability after subsequent component installation. The tool stabilizing mechanism 14 is set on the surface of the first crossbeams 17 to enhance the overall stability of the frame assembly and work with other components to maintain the overall machine posture during operation. One end of the contouring frame front connecting rod 15 is connected to the tool fixing frame 16, and the other end of the contouring frame front connecting rod 15 is connected to the second crossbeam 18, realizing the effective connection between the tool fixing frame 16 and the second crossbeam 18, making the force transmission smoother. A contouring floating frame 8 is set between two adjacent rows of second crossbeams 18, which can swing flexibly around the hinge point to adapt to terrain changes and provide key moving component support for macroscopic contouring. An independent elastic suspension mechanism is installed on the surface of the contour floating frame 8. It is fixed by welding and bolts to balance connection strength and maintenance convenience. It is used to achieve micro-contouring and overload protection, providing each seeding unit with independent degrees of freedom of movement. The range of movement can be designed according to the range of small undulations on the ground. At the same time, it protects the core components when the seeding unit encounters obstacles. The compaction pressure control mechanism is located on the surface of the second crossbeam 18 at the rear. It is used to realize terminal pressure regulation, provide continuous and adjustable downward pressure to the compaction wheel 6, ensure that the compaction force of the compaction wheel 6 on the soil is constant, and obtain a uniform compaction effect.

[0024] Please see the appendix Figure 1 The independent elastic suspension mechanism includes a ditching, seeding, and fertilization integrated device 7 and an elastic connecting plate 9. The ditching, seeding, and fertilization integrated device 7 is located at the bottom of the contour floating frame 8. The ditching components are made of wear-resistant alloy material to extend their service life. It is used to complete the integrated operation of ditching, seeding, and fertilization, thereby improving the working efficiency of the seeder. An elastic connecting plate 9 is provided between the ditching, seeding, and fertilization integrated device 7 and the contour floating frame 8. It is composed of a spring steel plate hinge mechanism and can provide downward working pressure to the ditching, seeding, and fertilization integrated device 7. The pressure can be adjusted by the specifications of the spring steel plate. It can also deform or rotate when it encounters an obstacle to achieve overload protection.

[0025] Please see the appendix Figure 1 and attached Figure 2The pressing pressure control mechanism includes a hydraulic cylinder connecting plate 3, a pressing hydraulic cylinder 4, a pressing linkage mechanism 5, and a pressing wheel 6. The hydraulic cylinder connecting plate 3 is set on the surface of the second crossbeam 18, providing stable installation support for the pressing hydraulic cylinder 4 and ensuring that the pressing hydraulic cylinder 4 does not shift its position during operation. The pressing linkage mechanism 5 is set on the surface of the hydraulic cylinder connecting plate 3 and adopts a multi-link structure design, which can flexibly adjust the height of the pressing wheel 6. It is used to connect the pressing hydraulic cylinder 4 and the pressing wheel 6 to achieve effective power transmission. The surface of the linkage is treated with anti-corrosion to prevent rust caused by field moisture. The pressing wheel 6 is set at the bottom of the pressing linkage mechanism 5 and is used to press the soil after sowing to ensure good contact between the seeds and the soil. The pressing hydraulic cylinder 4 is set on the surface of the pressing linkage mechanism 5 and is independent of the main contouring platform hydraulic circuit. It is equipped with an independent hydraulic oil pipeline to avoid mutual interference with the main circuit. It can provide downward pressure to the pressing wheel 6 under the control of the tractor hydraulic system.

[0026] Please see the appendix Figure 1 The first crossbeam 17 has a tractor suspension frame 1 in the middle, which is used to connect the frame assembly to the tractor and realize the suspension of the frame assembly. The suspension height can be adjusted by the tractor suspension system to adapt to different operating scenarios. The top of the tractor suspension frame 1 is connected to two implement fixing frames 16, which further enhances the connection stability between the tractor suspension frame 1 and the implement fixing frames 16. At the same time, the weight of seeds, fertilizers, etc. is borne by the tractor, avoiding affecting the sowing element and ensuring that the sowing element always maintains a stable working posture.

[0027] Please see the appendix Figure 1 The top of the tool fixing frame 16 is equipped with a hydraulic cylinder tie rod 2, which is used to connect the tool fixing frame 16 and the hydraulic cylinder connecting plate 3. One end of the hydraulic cylinder tie rod 2 is connected to the hydraulic cylinder connecting plate 3 to ensure reliable connection between the pressing pressure control mechanism and the tool fixing frame 16, ensure the stability of pressure transmission, and avoid loss or fluctuation during pressure transmission.

[0028] Please see the appendix Figure 1 - Appendix Figure 3 A ground wheel 10 is installed on the surface of the second crossbeam 18 at the front. The diameter of the ground wheel 10 is designed according to the looseness of the soil in the working area. It is used to support the frame assembly and allow the independent frame to float freely through the ground wheel 10. A grass cutting linkage mechanism 12 is installed at the bottom of the machine fixing frame 16. The linkage mechanism can realize the lifting and lowering adjustment of the grass cutting wheel 11 to adapt to weeds of different heights and provide a basis for the installation and movement of the grass cutting wheel 11. The grass cutting wheel 11 is installed at the bottom of the grass cutting linkage mechanism 12 to cut the weeds in the field before sowing and clear obstacles for sowing operations. A grass cutting hydraulic cylinder 13 is installed in the middle of the grass cutting linkage mechanism 12 to provide working power to the grass cutting wheel 11 and control the working state of the grass cutting wheel 11. The top of the grass cutting hydraulic cylinder 13 is connected to the machine fixing frame 16 to ensure that the grass cutting hydraulic cylinder 13 is installed firmly and can output power stably.

[0029] Please see the appendix Figure 1 Appendix Figure 4 and attached Figure 5 The front connecting rod 15 of the contouring frame includes several fixed flanges 151, several rubber sleeves 152, a first connecting arm 153 and a second connecting arm 154. One end of the first connecting arm 153 is connected to the second connecting arm 154, and the connection is fastened with bolts and nuts, forming the main structure of the front connecting rod 15 of the contouring frame, realizing the connection between components. The other end of the first connecting arm 153 and both ends of the second connecting arm 154 are provided with fixed flanges 151 for connecting with the tool fixing frame 16 and the second crossbeam 18 to ensure the tightness of the connection. Several fixed flanges 151 are respectively set on the surface of the tool fixing frame 16 and the surface of the second crossbeam 18 to fix the front connecting rod 15 of the contouring frame to other components. Rubber sleeves 152 are provided at the connection points of several fixed flanges 151 with the first connecting arm 153 and the second connecting arm 154, which can reduce vibration and wear at the connection points and improve the service life of the front connecting rod 15 of the contouring frame.

[0030] Please see the appendix Figure 3 The surface of the stabilizing mechanism 14 is equipped with two main hydraulic cylinders 141. The cylinder body and piston rod are respectively hinged to the main frame and the contour floating frame 8. The oil circuits are connected in parallel to form a closed loop. The loop is equipped with a hydraulic lock to prevent hydraulic oil backflow from causing contour failure. It can allow hydraulic oil to flow freely when the terrain is undulating, allowing the contour floating frame 8 to swing. At the same time, it generates anti-torsional resistance to suppress tilting. The anti-torsional resistance can be adjusted according to the operation requirements through the hydraulic system parameters.

[0031] Working principle: The frame assembly of this no-till seeder features a hydraulically linked contouring main platform, which plays a role in macroscopic contouring and stabilization. The contouring floating frame 8 is connected to the main beam through a hinge point. The cylinder bodies of the two main hydraulic cylinders 141 are hinged to the main frame, and their piston rod ends are hinged to the contouring floating frame 8. The oil circuits of the two cylinders are connected in parallel to form a closed hydraulic circuit. When the working terrain undulates from side to side, the hydraulic oil flows freely in the parallel cylinders, allowing the contouring floating frame 8 to swing flexibly around the hinge point, so that the whole machine platform adapts to the macroscopic terrain. This hydraulic interconnection structure can generate huge anti-torsional resistance, suppress the lateral tilt of the seeder, and increase the overall stability of the machine during operation and transportation.

[0032] The frame assembly also features an independent elastic suspension mechanism, which serves as a micro-contouring and overload protection mechanism. The elastic connecting plate 9 is composed of a spring steel plate hinge mechanism, providing each sowing unit with downward working pressure and independent degrees of freedom of movement. Each sowing unit can independently float up and down with slight undulations in the ground, absorbing local vibrations and ensuring the stability of the sowing depth of a single row. When a single sowing unit collides with an invisible obstacle, the elastic connecting plate 9 can deform or rotate around the hinge point, causing the unit to bounce up and protecting the core working components from damage.

[0033] The frame assembly also has a pressing pressure control mechanism, which plays the role of terminal pressure regulation. The cylinder body of the pressing hydraulic cylinder 4 is hinged to the main frame through the hydraulic cylinder connecting plate 3, and its piston rod is connected to the pressing linkage mechanism 5 through the hydraulic cylinder tie rod 2. This cylinder is independent of the hydraulic circuit of the main contouring platform and its pressure is controlled separately by the tractor hydraulic system. By supplying pressurized oil to the rodless chamber of the pressing hydraulic cylinder 4, a continuous and adjustable downward pressure can be provided to the pressing wheel 6. This pressure does not change drastically with the terrain undulation, ensuring that the pressing force of the pressing wheel 6 on the soil is constant and adjustable, thereby obtaining a uniform pressing effect.

[0034] The main frame is attached to and suspended from the tractor. The weight of seeds, fertilizer, hopper (full / empty), etc., is suspended by the tractor, so this does not affect the sowing element. This effectively frees up the frame. The independent frames have no independent mass and can float freely on the front and rear rollers via supports. The independent frames are connected to the main frame via flexible joints (at the front) and hydraulic cylinders (at the rear), so it remains stable on the Y-axis in the direction of travel, but it can rotate around this axis, as well as around the X-axis, and rise and fall around the Z-axis. The hydraulic cylinders are extended by manually adjustable pressure relief valves (but can also be managed and controlled electrically and electronically during operation). In the opposite direction, the cylinders are operated by open / close valves. During operation, a continuous flow of oil is required at the pressure reducing valve, which will initiate the extension of the hydraulic cylinder. At the same time, the open / close valve must remain closed (free / no pressure discharge). However, when the seeder is lifted, the valve will be in the open position until the hydraulic cylinder closes, allowing the frame to move completely freely without fixed points or rotating axes, unaffected by other masses or structures. Each frame can respond and adjust without external influence. In this way, even large machines with multiple frames can rely on each frame being connected to only one unit without being affected by it during operation. Through the adjustment of the pressure reducing valve, the machine can be adjusted according to specific working conditions, enabling it to efficiently adapt to various soil properties. Similarly, the degree of soil compaction by the rear rollers can be appropriately adjusted.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
