Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a driven traction strip seedbed electro-hydraulic control preparation unit and its operating implement. Background Technology

[0002] Tillage is one of the most basic operational steps in agricultural production. Its main purpose is to loosen and break up the soil through soil-contacting components, thereby improving the structure of the topsoil, promoting the coordination of water, fertilizer, air, and heat in the soil, and burying the compacted topsoil, along with weeds, stubble, insect eggs, grass seeds, green manure, or farmyard manure, at the bottom of the furrow. This process loosens the soil, eliminates weeds and pests, and improves soil fertility, creating favorable soil conditions for crop growth and development.

[0003] Strip farming is a tillage method that divides a field into long, narrow strips and alternates between them in a crop rotation system. It is used when slopes are too steep or when no other methods are available to prevent soil erosion. So-called "strip tillage," a technique that alternates between seedbed strips and straw mulch strips, is a major conservation tillage technique for black soils. By choosing strip tillage instead of no-till methods, the soil benefits from minimal machine intervention and faster warming of the strips, helping plants establish a growing environment. This results in deeper root systems, thus enhancing crop resistance to lodging. Yields can also be increased compared to no-till methods because the strips provide the ability to accurately place seeds and fertilizers. Strip tillage systems fall between conventional tillage and no-till. It offers agronomic benefits and reduces machinery costs. Strip tillers can be used for most soil types, such as corn, sunflower, canola (OSR), soybeans, and sugar beets. It is best suited for crops requiring precision planting. In response to the problems of traditional tillage causing significant disturbance to the soil surface, severe soil moisture loss, and damage to soil structure, as well as the inaccurate placement of seeds and fertilizers and high fuel consumption of no-till machinery, there is an urgent need for strip tillage machinery that meets the requirements of conservation tillage and is also highly efficient and energy-saving.

[0004] Chinese patent application CN118216244A discloses a strip tillage machine. It features a second connecting rod on an upper frame, with the bottom of the upper frame connected to a lower frame via a shock-absorbing mechanism. Tillers are evenly distributed on a second rotating shaft. A fertilizer bin and a continuous feeding and fertilizing mechanism are mounted on the upper frame. Multiple turntables and support frames are radially arranged around the outer circumference of a third connecting shaft, with the turntables and support frames spaced apart. A soil-breaking frame is movably installed between adjacent turntables. This strip tillage machine is an integrated workpiece, not individually adjustable, and requires power input to operate. Lacking an electro-hydraulic control system, it relies on mechanical structure adjustments and cannot meet diverse operational requirements.

[0005] Chinese patent application CN 109247089 A discloses a multi-functional corn planter for seedling strip management, including a traction frame, a suspension frame, a machine frame, a drive shaft, a gearbox, a stubble-removing mechanism, a rotary tillage mechanism, a deep loosening and fertilization mechanism, a sowing, furrowing, and compaction mechanism, and a soil-covering mechanism. The drive shaft is connected to the machine frame via the gearbox, and the traction frame and suspension frame are both connected to the machine frame. The stubble-removing mechanism includes a stubble-removing shaft, a connecting piece on the stubble-removing shaft, and a left and right blade connecting the connecting piece. The rotary tillage mechanism includes a rotary tillage shaft and rotary tillage teeth on the rotary tillage shaft. This implement is a combined land preparation and sowing machine, with a stubble-removing device at the front, driven by tractor power input, and adapted to lower operating speeds.

[0006] Chinese patent application CN112243622A discloses a beet strip tillage and deep fertilization integrated machine. This integrated machine has several fertilizer boxes mounted above the front frame and several deep tillage and fertilization plows below. Fertilizer discharge drives and depth limiting wheels are mounted on both sides of the front. Each fertilizer box has several fertilizer discharge trays at its lower part, and each fertilizer discharge tray is connected to a fertilizer discharge pipe, which is connected to the fertilizer pipe. A deep tillage shovel is mounted at the bottom of the deep tillage and fertilization plows. A transmission box is mounted on the rear frame, and a rotary tiller shaft is mounted at the lower rear of the rear frame. Several rotary tiller blades are evenly distributed around the rotary tiller shaft. A soil retaining cover is mounted below the rear frame and above the rotary tiller shaft. A press wheel is mounted at the rear end of the rear frame. The implement described in this patent still performs full-width rotary tillage. The strip tillage it refers to is achieved through several rotary tiller blade shafts, requiring power input from the tractor's power shaft. It cannot achieve land preparation solely through traction, and it lacks a single-group contouring function, so the work quality is affected by the flatness of the ground. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a driven traction strip seedbed electro-hydraulic control preparation unit and its operating equipment. Its structure is simple and reliable, and its functional layout is reasonably designed. It allows the soil to benefit from minimal machine intervention and faster heating of the strips, which helps plants grow faster, resulting in deeper root systems and thus enhancing the crop's resistance to lodging.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A driven traction strip seedbed electro-hydraulic control preparation unit and its operating implement include a frame. A depth-limiting opening component, a weed-removing component, a deep-loosening component, and a compaction component are sequentially installed on the frame from front to back. All components are individually attached to the ground. The depth-limiting opening component and the weed-removing component are connected to the frame via impact buffer springs. The upper front end of the frame is connected to a fixed frame via a first parallelogram linkage mechanism. The deep-loosening component is connected to the frame via a second parallelogram linkage mechanism. The compaction component is connected to the frame via a third parallelogram linkage mechanism. Electro-hydraulic rods are installed on the diagonals of the first, second, and third parallelogram linkage mechanisms; an electrical control box for controlling the electro-hydraulic rods is installed in the gap of the main frame.

[0009] The frame is an irregularly shaped sheet structure.

[0010] The depth limiting aperture assembly includes depth limiting wheels and an aperture disc respectively installed on both sides of the frame. The depth limiting wheels are fixedly installed on the frame, and the aperture disc is connected to the frame through an impact buffer spring.

[0011] The grass-removing assembly includes two grass-removing wheels, which are mounted on a grass-removing wheel frame. The upper end of the grass-removing wheel frame is mounted on the machine frame via an impact buffer spring.

[0012] The two grass-removing wheels are installed at a certain angle, asymmetrically distributed, and the working axes of the two grass-removing wheels are on the same straight line as the working strips of the front and rear components.

[0013] The subsoil assembly includes a subsoil shovel and guide vanes located on both sides of the subsoil shovel. The two guide vanes are symmetrically installed on the guide vane frame, and the upper end of the guide vane frame is fixed to the frame. The subsoil shovel is connected to the frame through a second parallelogram linkage mechanism.

[0014] A mudguard plate, which is installed on the frame, is provided on the rear side of the upper end of the guide vane frame.

[0015] The pressing assembly includes a pressing support wheel, which is installed at the end of the support wheel frame. The front end of the support wheel frame is connected to the frame through a third parallelogram linkage mechanism.

[0016] The electrical control box is designed as a covered structure, with its wide side fixedly covering the frame, and it features a side-opening door design.

[0017] The upper part of the frame is reserved with space for seed boxes and / or fertilizer boxes.

[0018] The beneficial effects of this invention are as follows: This invention utilizes pre-set damping parameters and a hydraulic structure design, employing diagonally placed hydraulic rods to achieve closed-loop control of the electro-hydraulic parallelogram mechanism, keeping the machinery in dynamic balance and ensuring smooth operation during tillage. The depth-limiting wheel and weed-removing wheel utilize pressure springs and connecting rods to allow for vertical floating, preventing overload. The stubble-clearing assembly uses a strip arrangement of depth-limiting wheels, opening discs, weed-removing wheels, deep loosening shovels, guide vanes, and support wheels to adjust the tillage sequence and achieve strip tillage. Each independent wheel in the working unit is a non-powered wheel, achieving independent transmission through contact force and friction with the ground, without interference. This invention allows the soil to benefit from minimal machine intervention and faster warming of the strips, helping plants grow faster, resulting in deeper root systems, thus enhancing crop lodging resistance, increasing yield, and reducing machinery costs.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0022] like Figure 1 As shown, a driven traction strip seedbed electro-hydraulic control preparation unit and its operating implements are disclosed. This implement can perform strip-shaped tillage on cultivated land. It mainly includes various operating implements, electro-hydraulic rods, and a quadrilateral linkage mechanism. The operating implements, electro-hydraulic rods, and quadrilateral linkage mechanism are all mounted on a frame 1. The frame 1 has an irregularly shaped sheet structure.

[0023] like Figure 2As shown, a depth-limiting wheel 3, an open-face disc 4, and a weeding wheel 6 are mounted on the frame 1. In this embodiment, the open-face disc 4 is connected to the frame 1 via a disc impact buffer spring 2, and the weeding wheel 6 is connected to the frame 1 via a weeding wheel impact buffer spring 5. The depth-limiting wheel 3 restricts the trenching depth of the open-face disc 4, which cuts through the surface layer of the cultivated land and cuts through plant debris, or uses a corrugated disc to provide better line expansion. The weeding wheel 6 clears weeds and clumps of soil from the cultivated strips. When encountering obstacles, the impact buffer springs can cause the open-face disc 4 and the weeding wheel 6 to float, buffering the impact force to prevent damage to the machinery from the impact of stones and soil clods. A spring with an appropriate spring coefficient is selected based on calibration to provide impact protection.

[0024] Both the optical disc impact buffer spring 2 and the grass-repelling wheel impact buffer spring 5 include a pressure spring and a telescopic rod, with the pressure spring sleeved on the telescopic rod. The cooperation between the pressure spring and the telescopic rod, as well as their cooperation with the open optical disc 4 and the grass-repelling wheel 6, is existing technology, similar to the elastic shock absorption systems of existing electric bicycles and motorcycles, and will not be elaborated further. The spring's deformation parameters are designed so that it can float up and down when subjected to hard objects such as stones during operation, preventing overload damage.

[0025] like Figure 3 As shown, a deep loosening shovel 8 is installed in the middle of the frame 1 via a second parallelogram linkage mechanism 16, and guide vanes 9 are symmetrically installed on both sides of the deep loosening shovel 8. The two guide vanes 9 are symmetrically installed on the guide vane frame 15, and the upper end of the guide vane frame 15 is fixed to the frame 1. A mudguard 14 installed on the frame 1 is provided on the rear side of the upper end of the guide vane frame 15.

[0026] The subsoil shovel 8 features a pointed tooth design with keyless adjustment. It cracks and loosens seedling lines, with the pointed teeth at an angle of approximately 30 degrees to the ground. The working depth can be adjusted from 7 cm to 30 cm, providing quick and precise results. The subsoil shovel 8 works in conjunction with the guide vanes 9. While breaking up the soil, the guide vanes 9 on both sides guide the soil flow as it is being formed, creating fine soil.

[0027] The rear of frame 1 is equipped with compaction support wheels 10, which work in conjunction with the stubble clearing assembly to support the entire machine. The compaction support wheels 10 are a symmetrically distributed, cross-shaped wheel system, which better creates fine backfill soil and provides a good environment for the seedbed. The compaction support wheels 10 are responsible for supporting the seedbed, breaking up soil clods, providing fine backfill soil, and preventing voids in the future planting area; they also consolidate the backfill soil at depth while avoiding compaction at the surface. The purpose is to break up soil clods to promote water penetration while retaining soil moisture. The pressure is adjustable, and different support heights are used for different seasons.

[0028] In this invention, the wheel systems of each stubble-clearing assembly are individually attached to the ground and can function independently. The depth-limiting wheel 3, the opening disc 4, the weed-removing wheel 6, the guide vane 9, and the compaction support wheel 10 are all non-powered components. During operation, they achieve independent, non-powered movement through the contact friction between each component and the soil, saving energy. The overall machine is propelled forward by a suspended traction mechanism, and the working strips can be extended from one row to multiple rows as needed. The opening disc 4 and guide vane 9 of this invention can be selected as either a disc or a curved disc depending on the geological conditions and soil type. It separates the soil to form the bottom of strips or channels. The disc produces a cleaner cut, while the curved disc provides a finer floor. The two weed-removing wheels 6 are installed at a certain angle, not symmetrically distributed, but it is necessary to ensure that the working axis of the weed-removing wheels is aligned with the working strips of the preceding and following components after installation.

[0029] like Figure 4 As shown, the frame 1 and the fixed frame 21 are connected by a first parallelogram linkage mechanism 19. A first electro-hydraulic rod 20 is installed on the diagonal of the first parallelogram linkage mechanism 19. Due to the special nature of the parallelogram, the overall up-down and back-and-forth movement can be achieved by controlling the extension and retraction of the first electro-hydraulic rod 20.

[0030] A second parallelogram linkage mechanism 16 is installed between the frame 1 and the deep tillage shovel 8. The frame 1 is used as one side of the second parallelogram linkage mechanism 16. A second electro-hydraulic rod 17 is installed on the diagonal. By controlling the extension and retraction length of the second electro-hydraulic rod 17, the tillage angle and depth of the deep tillage shovel 8 can be controlled simultaneously.

[0031] At the rear of the frame 1, a third parallelogram linkage mechanism 12 is formed by the support wheel frame 11. A third electro-hydraulic rod 13 is added on the diagonal. By controlling the extension and retraction of the third electro-hydraulic rod 13, the height adjustment of the pressing support wheel 10 can be realized.

[0032] like Figure 5 As shown, a control center box 18 for the electro-hydraulic rods is installed in the gap of the frame 1. The control box 18 realizes closed-loop control of the three electro-hydraulic rods on the frame 1. By analyzing the data measured in the pre-test, different thresholds are set for the three hydraulic rods in the control box 18. The computer in the control box calculates the operating threshold of the machine. Through the pressure sensor installed on the parallel four-bar linkage, the control of the electro-hydraulic rods is controlled to realize closed-loop control of pressure, ensuring the smooth operation of the machine and preventing excessive jumping and sinking.

[0033] In this embodiment, the three electro-hydraulic rods operate independently without affecting each other. The first electro-hydraulic rod 20 is responsible for adjusting the overall operating mode of the machine; the second electro-hydraulic rod 17 is responsible for adjusting the working mode of the deep tillage shovel 8 between 7-30 cm; and the third electro-hydraulic rod 13 is responsible for adjusting the height of the compaction support wheel 10, cooperating with the depth limiting wheel 3. The components of the machine work together to achieve strip tillage. Each electro-hydraulic rod is connected to the control box 18 through the first electro-hydraulic line 23, the second electro-hydraulic line 24, and the third electro-hydraulic line 23, respectively, to achieve closed-loop control. By setting an appropriate threshold, the resistance of each hydraulic rod is kept in a relatively balanced position. When encountering uneven land or ditches, the machine can operate smoothly without sudden up-and-down fluctuations, ensuring the integrity of the seedbed.

[0034] In this invention, the electrical control box 18 is installed in the gap of the frame 1, which makes reasonable use of space and facilitates installation. For ease of installation, the electrical control box 18 is designed as a cover structure, which only requires the wide side to be covered on the main frame and fixed with four fixing bolts 22. The electrical control box 18 adopts a side-opening door design, which not only conforms to the overall frame but also facilitates the setting of the hydraulic threshold. Sufficient space is left above the frame 1 to add a seed box or fertilizer box for integrated operation.

[0035] In actual use, through the combined action of the depth limiting wheel 3, the opening disc 4, the weeding wheel 6, the deep loosening shovel 8, the guide plate 9, the pressing support wheel 10, and the corresponding electro-hydraulic quadrilateral linkage mechanism and control box, the tractor-driven machinery can achieve unpowered strip tillage operations.

[0036] The frame 1 is provided with mounting holes and limit holes, and the maximum angle for dynamic adjustment is set. Through stress verification and constraint design, the electro-hydraulic rod, spring structure and parallelogram linkage mechanism are installed and fixed at the corresponding positions on the frame 1.

[0037] This machine offers excellent adaptability to various application conditions: liquid, solid, or slurry fertilization, different row widths, a variety of working parts and equipment options, and multiple frame options: 3m, 3.50m, 4.40m, and 6m.

[0038] The complete set of machinery can be equipped with stubble clearing and working components to support 4-12 rows as needed. During operation, the advantages of direct sowing can be utilized by maintaining a stubble cover. This facilitates the heating of seedlings for rapid plant initiation and helps retain organic matter and moisture between rows.

[0039] The operation process of the above-mentioned driven traction strip seedbed electro-hydraulic control preparation unit and its operating tools is as follows: Before operating machinery, conduct a thorough inspection of the soil, especially for analyzing soil composition (texture, mineral elements) and inspecting any compacted areas. Also, pay attention to the site's vegetation: areas where weeds can grow and areas with high pest incidence. The local climate should also be considered. During operation, after the machine is debugged, a tractor provides traction, connecting to the fixed frame 21 to drive the mechanical equipment forward. Based on the land conditions, the control system is adjusted, damping parameters are set, and the hydraulic rod extension distance is adjusted, causing the parallelogram mechanism to deform, thereby adjusting the depth of the depth-limiting wheel 3. The opening disc 4 cooperates with the depth-limiting wheel 3, achieving unpowered rotation through friction with the land, thus cutting plant fragments and providing expansion lines. Subsequently, the grass-removing wheel 6 removes the shredded grass from the disc, clears away stones and other residues, and breaks up small and medium-sized clods of soil.

[0040] The deep loosening shovel 8 works in conjunction with the guide plate 9. The sharp teeth of the deep loosening shovel 8 crack and loosen the seedling line. The loosened soil is guided by the guide plate 9 and forms fine soil to ensure the neatness between rows. Finally, the compaction support wheel 10 supports the seedbed, breaks up large soil clods, and forms backfill soil.

[0041] To prevent large stubble and stones in the soil from causing significant impact on the machinery, corresponding stress springs are installed between the grass-removing wheel 6 and the frame 1, and between the depth-limiting wheel 3 and the frame 1, to reduce stress and prevent the machinery from bearing excessive load.

[0042] Electro-hydraulic rods were installed on the trenching teeth of the opening disc 4, the compaction support wheel 10, and the deep loosening shovel 8. These mechanisms enable closed-loop control based on land conditions under varying environmental circumstances, automatically adjusting the machine's stability. This prevents the machine from fluctuating in elevation when the land is uneven, ensuring a level and uniform surface after tillage. At this point, all the machine's work is complete.

[0043] The left and right weeding wheels 6 are set at a suitable angle, and their spacing line is aligned with the strip tillage belt. The deep loosening shovel 8 is controlled by an electronic four-link system, with an adjustment range of 7-30 cm depending on the geological conditions. The entire machine is supported by the coordinated action of the various working wheels, and each component achieves unpowered movement without external power input through contact with the ground.

[0044] The three electro-hydraulic rods work independently without affecting each other. The first electro-hydraulic rod 20 is responsible for adjusting the overall operating mode of the machine. The second electro-hydraulic rod 17 is responsible for adjusting the working mode of the deep tillage shovel 8 between 7-30 cm. The third electro-hydraulic rod 13 is responsible for adjusting the height of the compaction support wheel 10 and cooperating with the depth limiting wheel. The components of the whole machine work together to achieve strip tillage. Each electro-hydraulic rod is controlled in a closed loop by the control box. By setting an appropriate threshold, the resistance of each hydraulic rod is kept in a relatively balanced position. When encountering uneven land or ditches, the machine can be guaranteed to run smoothly without sudden up and down fluctuations, thus ensuring the integrity of the seedbed.

[0045] This invention allows the soil to benefit from minimal machine intervention and faster warming of the strips, helping plants grow faster, which in turn produces deeper root systems, thereby enhancing crop lodging resistance, increasing yield, and reducing machinery costs.

[0046] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
