Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to an adjustable-depth no-till fertilization suspension structure. Background Technology

[0002] No-till farming, as a conservation tillage technique, reduces soil disturbance, conserves water and soil, and improves tillage efficiency, and is widely used in modern agriculture. The core of no-till fertilization is to precisely apply fertilizer to the soil by creating fertilization furrows through a furrowing device without tilling the soil. Therefore, the controllability of furrow depth, compatibility with power machinery, and operational stability are key technical indicators. Existing no-till fertilization devices suffer from the following shortcomings: They are cumbersome to connect to power machinery; traditional suspension structures often use fixed bolts, requiring the disassembly of multiple parts to adjust height and angle, which is time-consuming and labor-intensive when adapting to different tractor models, impacting operational efficiency; adjusting furrow depth is inconvenient—some devices adjust depth via mechanical gears, resulting in low precision and complex operation, making it difficult to adapt to the varying fertilization depth requirements of different crops; the furrowing blades are in direct contact with the soil, and impacts from stones or other hard objects can easily deform the blades or blade holders, leading to high maintenance costs and disruption of continuous operation; the furrowing disc is prone to soil adhesion in moist soil, causing furrow edge collapse and irregular shape, affecting fertilizer coverage; and some devices lack an effective mud scraping mechanism, requiring frequent shutdowns for cleaning. Therefore, we propose an adjustable-depth no-till fertilization suspension structure to address these problems. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable-depth no-till fertilization suspension structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-depth no-till fertilization suspension structure, including a no-till ditching blade assembly, a suspension bracket, an adjustable suspension, a quick-adjustable hanging frame, and a mounting frame. The quick-adjustable hanging frame is bolted to one side of the suspension bracket, and the no-till ditching blade assembly is provided on the side of the suspension bracket away from the quick-adjustable hanging frame. The mounting frame is movably connected to the side of the suspension bracket close to the no-till ditching blade assembly, and an adjustable suspension is provided between the mounting frame and the suspension bracket.

[0005] Preferably, the quick-adjustable hanging frame includes a hanging plate, a hook, a quick-release screw, and a mounting plate. The mounting plate is fixedly connected to one side of the hanging bracket, an adjusting rod is fixedly connected to the mounting plate, a quick-release screw is movably connected to the adjusting rod, the hanging plate is movably connected to the mounting plate through the quick-release screw, and a hook is fixedly connected below the scraper.

[0006] Preferably, the no-till ditching knife assembly is composed of a knife holder and a ditching knife. The knife holder is movably connected to one side of the suspension bracket, and the ditching knife is provided on one side of the knife holder. Fixing screws and safety screws are provided between the knife holder and the ditching knife.

[0007] Preferably, the trenching disc assembly is composed of trenching discs, with two sets of trenching discs symmetrically arranged. The trenching discs are fixedly connected to both sides of the mounting frame, and the trenching discs are arranged at an angle to each other.

[0008] Preferably, a scraper assembly is provided on one side of the mounting frame, and the scraper assembly cooperates with the trenching disc.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. The adjustable suspension can be adjusted in length via hydraulic rods, thereby changing the height of the mounting frame relative to the suspension bracket. Since the furrowing disc assembly is fixed on the mounting frame, the height of the no-till furrowing blade assembly is also linked to the relative position of the suspension bracket and the mounting frame. Therefore, changes in the height of the mounting frame will directly change the soil penetration depth of the furrowing blade and the furrowing disc. When the mounting frame is lowered, the furrowing components penetrate deeper into the soil, and when it is raised, they penetrate shallower. Through this adjustment, the fertilization depth requirements of different crops can be adapted.

[0010] 2. The mounting plate is fixed to the suspension bracket. The mounting plate is movably connected to the adjusting rod of the mounting plate via quick-release screws. The hook below the mounting plate directly hooks to the suspension point of the power machinery. Before operation, the height and horizontal position of the hanging plate and hook can be quickly adjusted by adjusting the position of the quick-release screws on the adjusting rod, ensuring that the connection angle and height of the overall structure match the power machinery. The quick-release screws facilitate efficient fixing or loosening. After connection, the traction force of the power machinery is transmitted to the suspension bracket through the quick-adjustable mounting structure, driving the entire structure to move synchronously with the power machinery, providing a power foundation for subsequent trenching operations.

[0011] 3. The tool holder is movably connected to one side of the suspension bracket. As the suspension bracket moves, it completes the initial trenching. When the power machinery moves forward, the trenching blade contacts the soil and breaks up the soil surface to form the initial fertilization trench. The fixing screw between the tool holder and the trenching blade ensures a stable connection between the two during normal operation. When the trenching blade encounters hard objects such as stones, the safety screw breaks first to prevent damage to the trenching blade or tool holder due to severe impact. Afterwards, only the safety screw needs to be replaced to resume operation, reducing maintenance costs.

[0012] 4. The furrowing disc assemblies on both sides of the mounting frame trim the initial furrows created by the no-till furrowing blade assembly to better meet fertilization needs. The two sets of furrowing discs are set at an angle. As the mounting frame moves, they will squeeze and scrape the soil at the edge of the furrow to both sides, further widening the furrow and trimming the furrow walls, making the furrow shape more regular, which facilitates the even distribution and coverage of subsequent fertilizer.

[0013] 5. The scraper assembly works in conjunction with the trenching disc to solve the problem of soil adhesion during trenching disc operation. When the trenching disc is working in moist soil, soil easily adheres to its surface. If not cleaned, this will increase trenching resistance and reduce the trenching effect. The scraper assembly is close to the surface of the trenching disc and can scrape off the soil adhering to its surface in real time as the trenching disc rotates, ensuring that the trenching disc always maintains efficient soil penetration and ensuring continuous operation.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0017] like Figures 1-4 As shown, the present invention proposes an adjustable depth no-till fertilization suspension structure, including a no-till ditching blade assembly 1, a suspension bracket 2, an adjustable suspension 3, a quick-adjustable hanging frame 4, and a mounting frame 7. The quick-adjustable hanging frame 4 is bolted to one side of the suspension bracket 2, and the no-till ditching blade assembly 1 is provided on the side of the suspension bracket 2 away from the quick-adjustable hanging frame 4. The mounting frame 7 is movably connected to the side of the suspension bracket 2 close to the no-till ditching blade assembly 1, and the adjustable suspension 3 is provided between the mounting frame 7 and the suspension bracket 2. The adjustable suspension 3 can be adjusted in length via a hydraulic rod, thereby changing the height of the mounting frame 7 relative to the suspension bracket 2. Since the furrowing disc assembly 6 is fixed on the mounting frame 7, the height of the no-till furrowing blade assembly 1 is also linked with the relative position of the suspension bracket 2 and the mounting frame 7. Therefore, the change in the height of the mounting frame 7 will directly change the soil penetration depth of the furrowing blade 102 and the furrowing disc. When the mounting frame 7 is lowered, the furrowing components penetrate deeper into the soil, and when it is raised, they penetrate shallower into the soil. Through this adjustment, the fertilization depth requirements of different crops can be adapted.

[0018] In an optional embodiment, the quick-adjustable hanging frame 4 includes a hanging plate, a hook 402, a quick-release screw 403, and a mounting plate 404. The mounting plate 404 is fixedly connected to one side of the hanging bracket 2. An adjusting rod is fixedly connected to the mounting plate 404. The quick-release screw 403 is movably connected to the adjusting rod. The hanging plate is movably connected to the mounting plate 404 through the quick-release screw 403. The hook 402 is fixedly connected below the scraper 401. The mounting plate 404 is fixed to the suspension bracket 2. The hanging plate 401 is movably connected to the adjusting rod of the mounting plate 404 via quick-release screws 403. The hook 402 below the hanging plate 401 directly hooks the suspension point of the power machinery. Before operation, the height and horizontal position of the hanging plate 401 and the hook 402 can be quickly adjusted by adjusting the position of the quick-release screws 403 on the adjusting rod to ensure that the connection angle and height of the overall structure and the power machinery are matched. The quick-release screws 403 facilitate efficient fixing or loosening. After connection, the traction force of the power machinery is transmitted to the suspension bracket 2 through the quick-adjustable hanging frame 4, driving the entire structure to move synchronously with the power machinery, providing a power foundation for subsequent trenching operations.

[0019] In an optional embodiment, the no-till ditching knife assembly 1 is composed of a knife holder 101 and a ditching knife 102. The knife holder 101 is movably connected to one side of the suspension bracket 2, and the ditching knife 102 is provided on one side of the knife holder 101. A fixing screw and a safety screw are provided between the knife holder 101 and the ditching knife 102. The ditching cutter 102 is movably connected to one side of the suspension bracket 2 via the cutter holder 101. As the suspension bracket 2 moves, it completes the initial trenching. When the power machinery moves forward, the ditching cutter 102 contacts the soil and breaks the soil surface to form the initial fertilization trench. The fixing screw between the cutter holder 101 and the ditching cutter 102 ensures a stable connection between the two during normal operation. When the ditching cutter 102 encounters hard objects such as stones, the safety screw breaks first to prevent damage to the ditching cutter 102 or the cutter holder 101 due to severe impact. The operation can be resumed by simply replacing the safety screw, thus reducing maintenance costs.

[0020] In an optional embodiment, the trenching disc assembly 6 is composed of trenching discs, with two sets of trenching discs symmetrically arranged. The trenching discs are fixedly connected to both sides of the mounting frame 7, and the trenching discs are arranged at an angle to each other. The furrowing disc assemblies 6 on both sides of the mounting frame 7 trim the initial furrows opened by the no-till furrowing blade assembly 1 to better meet the fertilization requirements. The two sets of furrowing discs are set at an angle. As the mounting frame 7 moves, they will squeeze and scrape the soil at the edge of the furrow to both sides, further widening the furrow and trimming the furrow walls, making the furrow shape more regular, so that the fertilizer can fall evenly and cover it.

[0021] In an optional embodiment, a scraper assembly 5 is provided on one side of the mounting bracket 7, and the scraper assembly 5 cooperates with the trenching disc. The scraper assembly 5 works in conjunction with the trenching disc to solve the problem of soil adhesion during trenching disc operation. When the trenching disc is working in moist soil, soil easily adheres to its surface. If not cleaned, this will lead to increased trenching resistance and poor trenching effect. The scraper assembly 5 is close to the surface of the trenching disc and can scrape off the soil adhering to its surface in real time as the trenching disc rotates, ensuring that the trenching disc always maintains efficient soil penetration and ensuring continuous operation.

[0022] The working principle of this utility model is as follows: When using the device, it is fixed on the suspension bracket 2 by the mounting plate 404. The hanging plate 401 is movably connected to the adjusting rod of the mounting plate 404 by the quick-release screw 403. The hook 402 below the hanging plate 401 directly hooks the suspension point of the power machinery. Before operation, by adjusting the position of the quick-release screw 403 on the adjusting rod, the height and horizontal position of the hanging plate 401 and the hook 402 can be quickly adjusted to ensure that the connection angle and height of the overall structure and the power machinery are matched. The quick-release screw 403 is convenient for efficient fixing or loosening. After connection, the traction force of the power machinery is transmitted to the suspension bracket 2 through the quick-adjustable hanging frame 4, which drives the entire structure to move synchronously with the power machinery, providing a power foundation for subsequent trenching operations. The ditching blade 102 is movably connected to one side of the suspension bracket 2 via the blade holder 101. As the suspension bracket 2 moves, it completes the initial trenching. When the power machinery moves forward, the ditching blade 102 contacts the soil and breaks the soil surface to form the initial fertilization trench. The fixing screw between the blade holder 101 and the ditching blade 102 ensures that the two are firmly connected during normal operation. When the ditching blade 102 encounters hard objects such as stones, the safety screw breaks first to prevent the ditching blade 102 or the blade holder 101 from being damaged by violent impact. Afterwards, only the safety screw needs to be replaced to resume operation, reducing maintenance costs. The furrowing disc assemblies 6 on both sides of the mounting frame 7 trim the initial furrows opened by the no-till furrowing blade assembly 1 to make them more suitable for fertilization. The two sets of furrowing discs are set at an angle. As the mounting frame 7 moves, they will squeeze and scrape the soil at the edge of the furrow to both sides, further widening the furrow and trimming the furrow wall, making the furrow shape more regular, so that the subsequent fertilizer can fall evenly and cover it. The scraper assembly 5 works in conjunction with the trenching disc to solve the problem of soil adhesion during trenching disc operation. When the trenching disc is working in moist soil, soil is easily stuck to the surface. If it is not cleaned, it will lead to increased trenching resistance and poor trenching effect. The scraper assembly 5 is close to the surface of the trenching disc and can scrape off the soil stuck to the surface in real time as the trenching disc rotates, ensuring that the trenching disc always maintains efficient soil penetration and ensuring continuous operation. Meanwhile, the adjustable suspension 3 can adjust its length via a hydraulic rod, thereby changing the height of the mounting frame 7 relative to the suspension bracket 2. Since the furrowing disc assembly 6 is fixed on the mounting frame 7, the height of the no-till furrowing blade assembly 1 is also linked with the relative position of the suspension bracket 2 and the mounting frame 7. Therefore, the change in the height of the mounting frame 7 will directly change the soil penetration depth of the furrowing blade 102 and the furrowing disc. When the mounting frame 7 is lowered, the furrowing components penetrate deeper into the soil, and when it is raised, they penetrate shallower into the soil. Through this adjustment, the fertilization depth requirements of different crops can be adapted.
