Description

Technical Field

[0001] This utility model relates to the technical field of deep loosening tools, specifically a biomimetic micro-thorn deep loosening shovel. Background Technology

[0002] Deep tillage is a farming technique that combines deep tillage implements with a tractor-powered platform. It's a new type of tillage method that uses tools such as deep tillage shovels, wallless plows, or chisel plows to loosen the soil without turning it over. Deep tillage is a new farming system that combines agricultural machinery and agronomy, and it is one of the main techniques of conservation tillage.

[0003] The deep tillage shovel is a core tool in agricultural tillage for loosening deep soil layers. Its main function is to break up compacted soil layers, deepen the tillage layer, and prevent surface soil overturning, thereby improving soil aeration, water retention, and permeability, creating a favorable environment for crop root growth. The deep tillage shovel typically consists of a handle, a tip, and wings. To reduce resistance when loosening soil, the tip often features a uniquely shaped biomimetic design, mimicking the structure and function of living organisms to solve complex problems in practical applications. For example, the existing technology "A Bionic Deep Tillage Shovel" (publication number: CN111034390A) mimics the surface geometry of soil-dwelling animals and aquatic scallops, featuring wings on both sides of the tip with a corrugated stripe drag-reducing structure on the upper surface; ribs and convex bumps on the upper part of the tip; and a soil guide plate at the front end of the handle. This structure reduces resistance during deep tillage. However, the existing technology still has the following technical problems: 1. Existing wing shovels are equipped with multiple corrugated strips, which are arranged along the direction of movement of the wing shovel during the deep loosening process. The purpose is to guide the soil when the deep loosening shovel moves, thereby reducing the resistance during the movement of the deep loosening shovel. However, during the process of loosening the soil, soil is easily trapped between the corrugated strips, especially in areas with high soil moisture. The accumulated soil blocks the spaces between the corrugated strips, causing the entire corrugated strip to lose its ability to guide the soil, thereby reducing the drag reduction effect of the entire deep loosening shovel.

[0004] 2. The tip of the existing deep loosening shovel is relatively long and pointed. Since the deep loosening shovel needs to be in continuous contact with the soil when it moves, the tip of the shovel is a stress concentration point, which makes it very easy to wear, reducing the service life of the deep loosening shovel and increasing maintenance costs. Utility Model Content

[0005] This invention provides a biomimetic micro-thorn deep loosening shovel, which can solve the problems of existing deep loosening shovels having structural shapes that easily reduce the resistance of the entire deep loosening shovel and are prone to wear.

[0006] This application provides the following technical solution: a biomimetic micro-thorn deep loosening shovel, including a shovel handle and a shovel tip fixed to the end of the shovel handle; the shovel tip includes a connecting part and side wings fixed on both sides of the connecting part; The surface of the connecting part and the side wing is evenly distributed with multiple spherical protrusions, and the outer periphery of the spherical protrusions is provided with micro-barbs, which are arranged in a direction away from the tip of the shovel.

[0007] Beneficial effects: This deep tillage shovel reduces movement resistance, minimizes wear, and extends its service life. The shovel tip includes a connecting section and side wings. The connecting section secures the entire shovel tip to the lower end of the handle, while the side wings loosen the soil. Spherical protrusions on the connecting section and side wings reduce the contact between the shovel tip and soil from a large surface contact to a more dispersed point contact. The spherical surface of the protrusions acts as a guide surface for the soil, improving its smooth movement and reducing resistance during shovel movement. Furthermore, the shape of the spherical protrusions ensures that the soil surface maintains a certain distance from the shovel tip surface as the shovel moves through the soil. The design incorporates gaps to prevent the soil from forming a sealed contact surface with the shovel tip. This reduces soil adhesion to the shovel tip, enhances the shovel's ability to agitate the soil, improves soil loosening, and prevents excessive resistance caused by soil accumulation on the shovel tip. Furthermore, the spherical protrusions are evenly distributed on the shovel tip. Compared to existing deep-loosening shovel structures, this design ensures that soil does not stagnate between the protrusions. The soil is always smoothly guided by the protrusions as the deep-loosening shovel moves, guaranteeing a stable drag reduction effect and reducing the difficulty of loosening soil with the deep-loosening shovel. The outer periphery of the spherical protrusion is equipped with micro-spiks oriented away from the tip of the shovel. Compared to the existing deep tillage shovel structure, the micro-spiks in this design are similar to the spikes on the surface of a living organism. When soil encounters the micro-spiks, they are directionally pushed aside, actively guiding the soil to move along the direction of the micro-spiks. This prevents soil from accumulating on the shovel surface, reduces the resistance of the soil to the shovel tip surface, and reduces the power load on the deep tillage machinery. At the same time, the micro-spiks can disperse the pressure of the soil on the shovel tip surface, reducing the frictional wear of the soil on the shovel tip surface, thereby reducing the wear of the shovel tip surface and extending the service life of the deep tillage shovel.

[0008] Furthermore, a gap is provided between the bottom of the micro-spiky protrusion on the spherical protrusion and the surface of the connecting part and the surface of the side wing.

[0009] Beneficial effects: By setting gaps between the bottom of the spherical protrusions and the surfaces of the connecting parts and the side wings, the soil can preferentially contact the micro-spiks before contacting the shovel tip surface. After the micro-spiks divert and guide the soil, the soil then contacts the shovel tip surface and moves along the direction of the shovel tip surface, which improves the soil guiding effect and prevents the soil from directly accumulating on the shovel tip surface and increasing resistance.

[0010] Furthermore, the side wing has a downward slope relative to the upper surface of the connecting part.

[0011] Beneficial effects: When loosening soil, the reverse compressive force of the soil on the shovel body is the core factor leading to increased resistance in deep loosening shovels. The inclined side wings can disperse soil resistance, allowing the soil to slide more smoothly along the side wings, avoiding the concentration of soil forces on the side wing surface, and preventing stress concentration at the shovel tip from aggravating wear.

[0012] Furthermore, the handle of the shovel is arc-shaped, and the inner side of the handle is provided with arc-shaped ribs.

[0013] Beneficial effects: The shovel handle features a rounded design with curved ribs on its inner side. Firstly, the rounded shape ensures the shovel tip, located below the handle, cuts into the soil at a specific angle during loosening, reducing soil resistance and making deep loosening easier. Secondly, the rounded handle structure resists bending deformation under stress, ensuring the handle's strength. The ribs on the inner side of the handle break through the soil during movement, further reducing soil resistance and improving overall deep loosening efficiency and handle lifespan.

[0014] Furthermore, the edge of the surface of the shovel tip is also provided with sheet-like protrusions, and the edges of the sheet-like protrusions are all provided with micro-barbs that protrude outwards.

[0015] Beneficial effects: The sheet-like protrusions with micro-spiked outer edges on both sides of the shovel tip surface serve several purposes. First, these protrusions reduce direct, large-area friction between the soil and the shovel tip surface, reducing soil adhesion and simultaneously acting as a prying tool to loosen gravel and reduce resistance. Second, the micro-spiked outer edges of these protrusions enhance soil breaking capacity, increase the soil breaking range, and prevent the formation of a soil compaction layer on the edges, unlike traditional shovel tips, further reducing resistance. In addition, the sheet-like protrusions and edge micro-spiked edges form a protective barrier, reducing direct friction and impact from hard objects such as gravel and grass roots on the shovel tip edge. This reduces shovel tip edge wear, extends the shovel tip's service life, and ensures stable breaking and guiding effects during long-term operation, thus guaranteeing the reliability and efficiency of the deep tillage shovel.

[0016] Furthermore, the sheet-like protrusions are hexagonal.

[0017] Beneficial effects: The hexagonal design of the sheet-like protrusions ensures that the six sides of the hexagon are evenly stressed. When the shovel tip cuts into compacted soil, it can distribute the soil impact force to each side. Combined with the shearing action of the micro-sharps on the edges, it can break up soil aggregates more efficiently and is less likely to deform due to excessive local stress, thus enhancing the breaking ability. At the same time, the hexagonal shape also makes it easier to distribute the micro-sharps more evenly on the outer periphery of the sheet-like protrusions, so that each side can be densely covered with multiple micro-sharps to improve the soil breaking ability in that direction and improve the breaking effect.

[0018] Furthermore, the spacing between each row of spherical protrusions is 1 / 5 to 1 / 3 of the diameter of the spherical protrusion.

[0019] Beneficial effects: This spacing range prevents blind spots in the guiding effect between adjacent spherical protrusions due to excessive spacing, preventing soil from directly contacting the shovel surface through the gaps between the protrusions without being guided by them, thus increasing the guiding effect of the spherical protrusions on the soil and improving the drag reduction effect of the subsoiler during movement. At the same time, this spacing range avoids the problem of excessively dense spherical protrusions leading to too small a gap between the soil and the shovel surface, resulting in reduced soil fluidity, thereby ensuring the shovel surface effectively disturbs the soil.

[0024] The following detailed description illustrates the specific implementation method: The markings in the accompanying drawings include: 1. handle, 2. arc-shaped rib, 3. connecting part, 4. side wing, 5. bolt, 6. spherical protrusion, 7. micro-spiky, 8. plate-like protrusion.

[0025] Example 1 like Figures 1 to 4 As shown, a biomimetic micro-thorn deep loosening shovel includes a handle 1 and a shovel tip fixed to the lower end of the handle 1. Figure 1As shown, the upper end of the shovel handle 1 has multiple screw holes for connecting to subsoil machinery. The shaft of the shovel handle 1 is generally arc-shaped, and the inner side of the shaft is provided with an integrally formed arc-shaped rib 2, with the edges of the arc-shaped rib 2 facing the inner arc side of the shovel handle 1. The arc-shaped shaft of the shovel handle 1 ensures that the shovel tip located below the shovel handle 1 cuts into the soil at a certain angle when loosening the soil. This reduces soil resistance when the subsoil shovel moves, reducing the difficulty of subsoiling. At the same time, the arc-shaped shaft structure of the shovel handle 1 can resist bending deformation after the shovel handle 1 is subjected to force, ensuring the strength of the shovel handle 1. The rib located on the inner side of the arc of the shovel handle 1 can break the soil when the subsoil shovel moves, further reducing soil resistance, improving the overall subsoiling efficiency and the service life of the shovel handle 1.

[0026] like Figure 2 As shown, the shovel tip is arrow-shaped and includes a one-piece connecting part 3 and side wings 4 fixed to both sides of the connecting part 3. The connecting part 3 is fixedly connected to the lower end of the shovel handle 1 by bolts 5, as shown. Figure 3 As shown, the side wing 4 has a downward slope relative to the upper surface of the connecting part 3. When loosening soil, the reverse squeezing force of the soil on the shovel body is the core factor that causes the resistance of the deep loosening shovel to increase; while the inclined side wing 4 can disperse the soil resistance, allowing the soil to slide more smoothly along the side wing 4, avoiding the soil force from concentrating on the surface of the side wing 4, and preventing stress concentration at the shovel tip from aggravating wear.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, the surfaces of the connecting part 3 and the side wing 4 are evenly distributed with multiple spherical protrusions 6. The spacing between each row of spherical protrusions 6 is 1 / 5 to 1 / 3 of the diameter of the spherical protrusion 6. The outer periphery of the spherical protrusions 6 is provided with micro-spiks 7. The micro-spiks 7 of the spherical protrusions 6 are arranged in the direction away from the tip of the shovel, that is, the direction of the micro-spiks 7 on the spherical protrusions 6 is opposite to the direction of the entire side wing 4 in the direction of loosening soil movement. There is a gap between the bottom of the micro-spiks 7 on the spherical protrusions 6 and the surface of the connecting part 3 and the surface of the side wing 4. The spherical protrusions 6 on the connecting part 3 and the side wings 4 resemble scales and spikes on the surface of an organism. This allows the contact between the entire shovel tip and the soil to be broken down from a large-area surface contact to a point-like, dispersed contact. The spherical surface of the protrusions 6 forms a guiding surface for the soil, improving the smoothness of soil movement on the protrusions and reducing resistance during the movement of the submersible shovel. Furthermore, the structural shape of the protrusions 6 creates a certain gap between the soil and the surface of the shovel tip when the submersible shovel is inserted into the soil, preventing a sealed contact surface and reducing soil adhesion to the tip surface, thus preventing excessive resistance caused by soil accumulation. The even distribution of the protrusions 6 on the shovel tip prevents soil from accumulating between them. The soil is consistently guided smoothly by the protrusions during the movement of the submersible shovel, ensuring a stable drag-reduction effect and reducing the difficulty of loosening soil. This also reduces the difficulty of moving the submersible shovel. The spherical protrusion 6 has micro-spurs 7 on its outer periphery, oriented away from the tip of the shovel. Similar to the directional structure of spikes on a living organism, soil encountering the micro-spurs 7 is directed and dispersed, actively guiding the soil along the direction of the micro-spurs 7. This prevents soil accumulation on the shovel surface, reduces soil resistance to the shovel tip surface, and lessens the power load on the subsoiler. Simultaneously, the micro-spurs 7 disperse the soil pressure on the shovel tip surface, reducing frictional wear and extending the service life of the subsoiler. Furthermore, gaps are provided between the bottom of the micro-spurs 7 on the spherical protrusion 6 and the surface planes of the connecting part 3 and the side wings 4. This gap allows the soil to first contact the micro-spurs 7 before contacting the shovel tip surface during the subsoiler's loosening process. The micro-spurs 7 first divert and guide the soil before it contacts the shovel tip surface and moves along its direction, improving the soil guidance effect and preventing soil from directly accumulating on the shovel tip surface and increasing resistance.

[0028] like Figure 4As shown, the edge of the shovel tip surface is also provided with plate-shaped protrusions 8. The plate-shaped protrusions 8 are hexagonal and are evenly spaced along both sides of the shovel tip edge. Each edge of the plate-shaped protrusions 8 has micro-spiks 7 protruding outwards. The plate-shaped protrusions 8 with micro-spiks 7 on the outer periphery of the shovel tip surface serve two purposes. First, the plate-shaped protrusions 8 can reduce the direct large-area friction between the soil and the shovel tip surface, reduce soil adhesion, and also have the effect of prying up gravel, reducing resistance. Second, the micro-spiks 7 on the outer periphery of the plate-shaped protrusions 8 can enhance the soil breaking ability, increase the soil breaking range, and prevent the soil compaction layer left on the edge of traditional shovel tips, further reducing resistance. In addition, the plate-shaped protrusions 8 and the edge micro-spiks 7 can also form a protective barrier to reduce the direct friction and impact of hard objects such as gravel and grass roots in the soil on the edge of the shovel tip, thereby reducing the wear of the shovel tip edge, extending the service life of the shovel tip, ensuring the stable breaking and guiding effect of the shovel tip during long-term operation, and providing a guarantee for the reliability and efficiency of deep loosening.

[0029] The method of using this subsoil shovel is as follows: First, the entire shovel handle 1 is connected to the subsoiling machine through the screw hole at the upper end of the handle 1. The shovel tip is inserted into the soil. Under the action of the subsoiling machine, the entire subsoiling shovel will move in the direction pointed by the shovel tip to loosen the soil. During this process, the spherical protrusion 6 guides the soil, and the micro-spiks 7 on the spherical protrusion 6 can guide the soil and prevent the soil from accumulating on the surface of the shovel tip, thereby reducing the resistance of subsoiling. The plate-shaped protrusion 8 located on the edge of the shovel tip and the micro-spiks 7 on the plate-shaped protrusion 8 can enhance the soil breaking ability, increase the soil breaking range, and prevent the soil compaction layer left on the edge of the traditional shovel tip, further reducing resistance. At the same time, it reduces the direct friction and impact of hard objects such as gravel and grass roots in the soil on the edge of the shovel tip, thereby reducing the wear of the shovel tip edge and extending the service life of the shovel tip.
