Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a soil turning and covering component for a hand-push fertilizer spreader. Background Art

It can realize the integrated operation of soil turning, fertilization and soil covering at the same time.

[0004] However, for some seeds, there are different requirements for the amount of soil covering. For example, large seeds such as corn and beans usually require deeper sowing holes and a moderate thickness of soil covering to ensure the humidity environment required for seed germination, while preventing the influence of bird pecking and wind erosion; while small seeds such as vegetable and flower seeds require shallow sowing and the soil covering should not be too thick, so as not to affect the strength of the seeds to break through the soil, and to prevent the seeds from rotting due to lack of oxygen. Although the existing small agricultural fertilizer spreaders have realized the integrated operation of turning over the soil, fertilizing and covering the soil, they may have limitations in terms of different requirements for different seed types and their different amounts of soil covering, and cannot flexibly adjust the working depth and covering amount of the covering plow. Utility Model Content

[0005] The utility model aims to provide a soil turning and covering component for a hand-push fertilizer spreader, so as to solve the problem of limitations in meeting the differentiated requirements for different seed types and their soil covering amounts.

[0007] A soil turning and covering assembly for a hand-push fertilizer spreader comprises a frame, a soil turning plow and a soil covering plow, wherein the soil turning plow is arranged below the frame and has a plow wall; the soil covering plow is arranged below the frame and at one side of the tail of the plow wall, and the soil covering plow has a first soil covering portion and a second soil covering portion, both of which are movably connected to the soil covering plow, a first bulldozing surface is formed on the first soil covering portion, and a second bulldozing surface is formed on the second soil covering portion; wherein, when the first soil covering portion and / or the second soil covering portion are movable, the first bulldozing surface and / or the second bulldozing surface form an angle with the extended surface of the plow wall.

[0008] Furthermore, the first bulldozing surface and the second bulldozing surface both have an inner side and an outer side, and along the height direction of the plow wall, the inner sides of the first bulldozing surface and the second bulldozing surface are located at a lower side of the outer side.

[0009] Furthermore, along the plowing direction of the plow wall, the first bulldozing surface and the second bulldozing surface gradually converge.

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Embodiment 1:

[0025] like Figure 1-2 As shown, the present embodiment provides a soil turning and covering assembly for a hand-push fertilizer spreader, including a frame 10, a soil turning plow 20 and a soil covering plow 30. The frame 10 serves as the main supporting structure, responsible for carrying and fixing other functional components. The frame 10 is generally made of high-strength steel or other lightweight, wear-resistant and corrosion-resistant materials, such as aluminum alloy or high-strength composite materials, to ensure that it maintains sufficient rigidity and deformation resistance while bearing various soil loads and the weight of mechanical components, thereby maintaining stable operating performance under long-term use and complex field environments.

[0026] The tiller 20 is usually fixed to the bottom of the frame 10 by high-strength bolts to ensure sufficient connection strength and stability between the tiller and the frame 10 during tilling operation. The upper surface of the tiller 20 is the tiller wall 201, which is usually sharp and slightly curved, specifically a V-shaped or U-shaped design that is narrow in front and wide in the back.

[0027] The front edge (plow tip) of the plowboard 201 is finely ground and hardened, sharp and strong, and can be easily inserted into and cut the soil, effectively reducing the resistance to turning over the soil. The arc surface design in the middle of the plowboard 201 allows the turned-up soil to flow smoothly to both sides along the plowboard 201 to avoid blockage. The rear of the plowboard 201 (plow heel) is relatively wide and has a certain height, ensuring that the turned-up soil can be fully turned over and dispersed after plowing, and can also help maintain the stability and guidance of the plow during operation.

[0028] In addition, the surface of the plow wall 201 is also treated with rust prevention and wear resistance to cope with the complex and changeable soil environment and the wear caused by long-term use. The plow wall 201 formed on the plow wall 201 can accurately control the depth and range of soil turning through scientific surface design and angle planning, thereby achieving coordinated work with the subsequent covering plow 30 to achieve an ideal hole fertilization effect and improve fertilization efficiency and crop yield.

[0029] The soil covering plow 30 is fixedly connected to one side of the tail of the plow wall 201 below the frame 10, and is usually fixedly installed using fasteners such as bolts to ensure that the soil covering plow 30 maintains a stable connection with the frame 10 during operation without displacement or loosening.

[0030] A part of the soil covering plow 30, namely the first soil covering part 301 and the second soil covering part 302, is movably connected to the main body of the soil covering plow 30. Specifically, the first soil covering part 301 and the second soil covering part 302 can be connected to the main body of the soil covering plow 30 through mechanical devices such as a pivot, a hydraulic cylinder or a chain. When the operator adjusts these movable connection devices, the angle of the first soil covering part 301 and / or the second soil covering part 302 will change, thereby making the first bulldozing surface 3011 and / or the second bulldozing surface 3021 form different angles with the extended surface of the plow 201 on the plow 201, thereby achieving precise adjustment of the amount of soil covering.

[0031] In actual application, the first soil covering part 301 and the second soil covering part 302 can be connected to the main body of the soil covering plow 30 through an adjustable mechanism such as a threaded rod. The operator only needs to simply screw the threaded rod to adjust the position and inclination angle of the first soil covering part 301 and the second soil covering part 302 relative to the plowboard 201. In this way, the angle formed by the first bulldozing surface 3011 and the second bulldozing surface 3021 and the extended surface of the plowboard 201 changes accordingly, further changing the area and method of their contact with the newly turned soil.

[0032] By adjusting the contact state between the first bulldozing surface 3011 and the second bulldozing surface 3021 and the soil, the thickness and range of the soil covering can be finely controlled, thereby meeting the personalized needs of different crops for the amount of soil covering. For example, for large-grained seed crops that require deeper soil covering, the contact area and strength between the bulldozing surface and the soil can be increased, while for small-grained seed crops that require shallow soil covering, the contact area can be appropriately reduced to ensure that the seeds are properly covered with soil without being too deep or too shallow, thereby optimizing the planting effect and crop growth conditions.

[0033] Embodiment 2:

[0034] like Figure 3 As shown, based on the above embodiment, the first bulldozer surface 3011 and the second bulldozer surface 3021 are designed to be lower inside than outside along the height direction of the plow wall 201. Specifically, the first bulldozer surface 3011 and the second bulldozer surface 3021 can be an inclined surface. The purpose of such structural design is to allow the soil to flow more smoothly to the center of the plow wall 201 after the plow tool turns the soil, thereby achieving good gathering and covering adjustment of the soil.

[0035] For example, when performing hole-fertilization operation on certain crops, the thickness of the covering soil needs to be adjusted to meet the growth requirements of the crop root system. When the thickness of the covering soil needs to be reduced, the installation height of the first and second bulldozer parts on the plow wall 201 can be increased to reduce the depth of their insertion into the turned-over soil, so that the contact area between the first bulldozer surface 3011 and the second bulldozer surface 3021 and the soil will also be reduced accordingly, thereby achieving the purpose of shallow covering soil.

[0036] On the contrary, if the thickness of the soil covering needs to be increased, such as when sowing crops that require deep soil covering, the installation height of the first bulldozer part and the second bulldozer part on the plow wall 201 can be lowered so that they can be inserted deeper into the turned soil. In this way, the contact area between the first bulldozer surface 3011 and the second bulldozer surface 3021 and the soil will be increased, thereby achieving the effect of deep soil covering.

[0037] Embodiment 3:

[0038] On the basis of the above embodiment, along the plowing direction of the plowboard 201, the first bulldozing surface 3011 and the second bulldozing surface 3021 are designed to gradually converge, that is, from the front end (plow tip) to the rear end (plow heel) of the plowboard 201, the distance between the first bulldozing surface 3011 and the second bulldozing surface 3021 gradually decreases, forming a structure similar to a trapezoid or an inverted V. With this design, the contact area with the turned soil can be changed by adjusting the convergence angle of the first bulldozing surface 3011 and the second bulldozing surface 3021, thereby adjusting the thickness and range of the covering soil.

[0039] For example, the first bulldozing surface 3011 and the second bulldozing surface 3021 can be designed as two inclined panels with a certain inclination angle. The width of the two panels is larger at the plow tip, like a pair of open wings. As the plow moves along the plowing direction, the width of the two panels gradually decreases until they are almost attached together when approaching the plow heel. In this way, the retraction angle of the first bulldozing surface 3011 and the second bulldozing surface 3021 can be adjusted as needed, thereby changing their contact area with the turned soil, thereby achieving precise control of the soil cover thickness and coverage range.

[0040] In specific application scenarios, when shallow soil covering is required, the expansion angle of the bulldozer surface can be appropriately increased to make the soil contact area relatively small. On the contrary, if deep soil covering or a larger range of soil covering is required, the expansion angle of the bulldozer surface can be reduced.

[0041] Embodiment 4:

[0042] like Figure 4 As shown, based on the above embodiment, the first bulldozing surface 3011 and the second bulldozing surface 3021 not only gradually converge along the plowing direction of the moldboard 201, but also have a front end and a rear end in their respective structures. A first arc portion 40 is formed between the front end and the rear end. The first arc portion 40 is a curved surface structure, and its center points outward, that is, toward the two sides of the moldboard 201.

[0043] For example, the first bulldozing surface 3011 and the second bulldozing surface 3021 can be inclined surfaces of two wedge-shaped bodies, the front ends of the two wedge-shaped bodies are wider, and the rear ends are gradually narrowed, and where the front ends and the rear ends are connected, an arc-shaped surface convex outward is designed, which is the first arc portion 40. When the plow is working, this arc-shaped structure is like a shovel, which can more smoothly guide and gather the soil turned up by the plow wall 201 to the center of the plow, and because of its outward-facing design, it can also effectively reduce the lateral splashing of the soil, so that the soil can be better concentrated in the direction of the plow, thereby accurately controlling the thickness and range of the covering soil.

[0044] In addition, the design of the first arc portion 40 can also reduce the impact force when the plow contacts the soil, reduce the wear of the plow, and increase its service life. By adjusting the shape and size of the arc portion, the adjustment of the amount of soil covering can be further refined to meet the differences in soil covering requirements of different crops.

[0045] Embodiment 5:

[0046] Based on the above embodiment, the curvature of the first arc portion 40 decreases from the front end to the rear end of the first bulldozer surface 3011 and the second bulldozer surface 3021. The purpose of this design is to complement and coordinate with the mechanism of gradually converging the first bulldozer surface 3011 and the second bulldozer surface 3021, so as to more efficiently regulate the soil flow speed and covering thickness during the covering process.

[0047] For example, when the plow starts to turn the soil, the large curvature design of the front end of the first arc portion 40 can gently and effectively guide and gather the soil turned up by the plow wall 201, avoiding the waste of soil due to high-speed throwing, and preparing for the subsequent covering work. As the plow moves forward, the distance between the first bulldozing surface 3011 and the second bulldozing surface 3021 gradually shrinks, and the decreasing curvature of the first arc portion 40 allows the soil to be squeezed and covered to the fertilization area at a suitable speed and thickness at the rear end of the plow, thereby achieving precise control of the amount of covering.

[0048] Moreover, when planting crops that require shallow soil covering, the expansion angles of the first bulldozer surface 3011 and the second bulldozer surface 3021 can be appropriately increased, so that the contact area between the bulldozer surface and the soil is relatively small, thereby reducing the thickness of the soil turned up by the front end of the plow. At the same time, combined with the curvature design of the first arc portion 40, that is, the curvature of the first arc portion 40 decreases from the front end to the rear end of the first bulldozer surface 3011 and the second bulldozer surface 3021, as the plow plows forward, the contact area between the bulldozer surface and the soil will be further reduced, thereby quickly achieving the adjustment of the amount of soil covering.

[0049] Embodiment 6:

[0050] like Figure 4 Therefore, based on the above embodiment, a second arc portion 50 is formed between the inner side and the outer side of the first bulldozing surface 3011 and the second bulldozing surface 3021. This design is intended to further optimize the distribution and flow of soil during the process of turning over and covering the soil. Specifically, the center of the second arc portion 50 faces the outer side of the plowboard 201, that is, faces both sides of the plow moving direction.

[0051] When the plow is working, the plowboard 201 first turns up the soil and disperses it to both sides. At this time, the second arc portion 50 located between the inner and outer sides of the first bulldozing surface 3011 and the second bulldozing surface 3021 plays an important role. Since the center of the second arc portion 50 points to the outer side of the plowboard 201, it can better guide and evenly disperse the turned-up soil along the plowboard 201 to both sides, avoiding soil accumulation in the center area of ​​the plow, thereby achieving good dispersion and coverage of the soil.

[0052] For example, when planting crops with a small planting distance or requiring shallow covering, the design of the second arc portion 50 helps to quickly and effectively push the soil to both sides, and then gradually close the first bulldozer surface 3011 and the second bulldozer surface 3021 to perform a thin layer of soil covering, thereby ensuring that the soil thickness around the seeds is moderate, which is conducive to seed germination and growth; and when planting crops that require deep covering or a wide covering range, the second arc portion 50 can also work together to ensure that the soil is evenly distributed in the fertilization area to achieve an ideal covering effect.

[0053] Embodiment 7:

[0054] like Figure 5 As shown, based on the above embodiment, a blocking portion 60 is additionally provided on the outer sides of the first bulldozing surface 3011 and the second bulldozing surface 3021. The blocking portion 60 forms a bent structure inwardly compared to the outer edges of the first bulldozing surface 3011 and the second bulldozing surface 3021. The purpose of this design is to optimize the soil control effect during the soil covering process, prevent the soil from being lost too quickly from both sides of the plow, and at the same time, adjust the soil flow direction to ensure that it covers the fertilization area more concentratedly.

[0055] In actual operation, when the soil turning plow 20 of the hand-push fertilizer spreader turns up the soil, the first bulldozing surface 3011 and the second bulldozing surface 3021 will guide the soil to gather toward the center. At this time, the blocking portion 60 disposed on the outside can effectively reduce the splashing or loss of soil along the two sides of the plow due to its inward bending design feature, and enhance the restraint force on the soil, so that the soil can be evenly and accurately pushed into the planting groove according to the preset angle and range, thereby achieving precise soil covering operation.

[0056] Working principle:

[0057] When the equipment is in use, the tiller 20 located below the frame 10 first contacts the soil, and the tiller wall 201 cuts and turns the soil, evenly distributing the soil to both sides, while preparing for subsequent soil covering operations.

[0058] The first soil covering part 301 and the second soil covering part 302 are movably connected to the soil covering plow 30, and the operator can adjust their positions and angles as needed. When the first bulldozing surface 3011 and / or the second bulldozing surface 3021 form a certain angle with the extended surface of the plow wall 201 on the plow wall 201, the contact area of ​​the bulldozing surface with the newly turned soil can be changed, thereby controlling the thickness and range of soil covering.

[0059] Along the height direction of the plowboard 201, the first bulldozing surface 3011 and the second bulldozing surface 3021 are lower inside than outside, and the design of the two gradually closing together helps to guide the soil to gather toward the center. The curvature of the first arc portion 40 decreases from the front end to the rear end, so that the soil is gradually covered to the fertilization area as the plow moves forward.

[0060] The second arc portion 50 ensures that the soil can flow along the designed path, and the blocking portion 60 disposed outside is bent inward to effectively prevent the soil from splashing from the side, thereby ensuring the soil covering effect and adjusting the depth and width of the soil covering according to needs.

[0061] When multiple illustrative embodiments are mentioned in this specification, it means that the specific structure described in conjunction with the embodiment is included in at least one embodiment generally described in this application. The same expression appearing in multiple places in the specification does not necessarily refer to the same embodiment.
