Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and more specifically, to an anti-tangling deep tillage rotary tillage blade. Background Technology

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] A rotary tiller is a farmland tillage implement driven by the power take-off shaft of a tractor. Its core working component is a high-speed rotating cutter shaft. By installing several rotary blades on the cutter shaft, it has been widely used due to its strong soil-breaking ability and the ability to flatten the soil surface after tilling. The rotary tiller rotates under the drive shaft of the implement through the rotation of the rotary blades, while the machine moves forward in a straight line. The rotary blades cut into the soil and throw the cut soil clods. After colliding with the soil retaining plate, the soil is further broken up and dragged to flatten the surface. The rotary tiller has the functions of breaking up the plow pan, restoring the soil structure, improving the soil's water retention capacity, eliminating some weeds, reducing pests and diseases, leveling the surface, and improving the standard of agricultural mechanization operations.

[0004] When traditional rotary tillers are used in fields rich in weeds, straw, or plastic film, the hook-shaped tip of the rotating blade first contacts the weeds or straw. Since traditional rotary tillers are not designed to cut these fibrous materials, the fibers easily get caught on the blade. As the blade continues to rotate, the caught material slides towards the root of the hook, which is the position with the smallest radius of curvature on the rotary tiller. Once the fibrous material reaches the root of the hook, under the combined action of centrifugal force and friction, the fibrous material curls around the mounting arm and blade holder of the blade, while a small amount of soil mixes with the weeds to form a tangled core, eventually forming a mixed tangled mass of fibrous material and soil on the blade shaft.

[0005] When fibrous materials become entangled on the cutter shaft, they significantly increase rotational resistance, leading to a sharp increase in the tractor's power output load and fuel consumption. In severe cases, the entangled material can rub against and jam against the rotary tiller's casing, forcing the rotary tiller to stop frequently and requiring a lot of time and effort for manual cleaning. Utility Model Content

[0006] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide an anti-tangling deep tillage rotary tillage blade, which can reduce the tangling of fibrous materials and reduce the time and labor costs of cleaning the blade.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] An anti-tangling deep tillage rotary tillage tool includes a mounting part, one end of which is fixedly provided with an extension part, and a tillage part is fixedly provided on the side of the extension part away from the mounting part. The extension part is arc-shaped, and the tillage part is straight. The extension direction of the tillage part is adapted to the radial direction of the extension part. The mounting part is horizontally arranged, and the extension direction of the mounting part is adapted to the tangent of the end of the extension part away from the tillage part.

[0009] In some possible embodiments, one end of the tillage section away from the extension is set as a right angle, and the other end is set as a rounded corner.

[0010] In some possible embodiments, a mounting hole is provided on the side of the mounting portion away from the extension portion. The mounting hole is provided through the entire portion. There are two mounting holes, which are respectively located on both sides of the mounting portion along the width direction of the mounting hole.

[0011] In some possible embodiments, the end of the mounting portion away from the extension portion is provided with a mounting ramp, and the inclination angle of the mounting ramp is set to 30°-45°.

[0012] In some possible embodiments, the two mounting holes are located at the upper and lower ends of the mounting ramp, respectively.

[0013] In some possible embodiments, the mounting ramp is configured as a straight surface, and the two ends of the mounting ramp are provided with arc-shaped connecting surfaces.

[0014] In some possible embodiments, the mounting ramp is configured as an arc-shaped surface, with the convex side of the arc-shaped surface facing the mounting hole.

[0015] In some possible embodiments, the end of the mounting portion away from the extension portion is provided with a first connecting slope, a second connecting slope and a third connecting slope. The bottom end of the first connecting slope is connected to the bottom edge of the mounting portion, and the top end is connected to the bottom edge of the mounting slope. The bottom end of the second connecting slope is connected to the top edge of the mounting slope. The top end of the third connecting slope is connected to the top edge of the mounting portion, and the top end of the second connecting slope is connected to the bottom end of the third connecting slope.

[0016] In some possible embodiments, a guide surface is connected between the top end of the second connecting inclined surface and the bottom end of the third connecting inclined surface. The guide surface is arc-shaped, and the angle between the extending directions of the second and third connecting inclined surfaces is acute.

[0017] In summary, the technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0018] 1. By designing the tillage section as a straight plate and smoothly connecting it with the arc-shaped extension section, the hook-like structure that is prone to forming a tangled core at the root of the traditional curved blade is eliminated. The straight plate tillage section can effectively cut rather than hook fibrous materials, while the streamlined overall contour makes it difficult for weeds, straws, etc. to get stuck when in contact and they are quickly thrown off under the action of centrifugal force, which significantly reduces the tangling and accumulation of materials on the cutter shaft, thereby reducing the frequency of downtime for cleaning and power consumption.

[0019] 2. In actual use, the arc-shaped extension is responsible for smoothly lifting the soil, while the straight tillage section cuts into the soil with less resistance and guides the soil clods to the rear. This not only reduces the resistance to soil entry and helps to achieve a deeper tillage depth, but also optimizes the soil throwing trajectory and breaking method, making the soil clods easier to break when they hit the baffle, thereby obtaining a finer and flatter topsoil layer.

[0020] 3. The mounting section is equipped with a mounting bevel at a specific angle and mounting holes distributed on its upper and lower sides. This structure ensures that the tool and the tool holder can be tightly and firmly installed, effectively reducing the loosening and swinging of the tool during operation, and improving the rigidity and stability of the overall structure. Stable installation is a prerequisite for ensuring continuous and efficient farming, and can also reduce premature wear and failure of components caused by vibration and impact.

[0021] 4. The end of the mounting section adopts a composite design of multiple connecting inclined surfaces and guide surfaces. In particular, the combination of the second and third connecting surfaces with acute angles and the arc-shaped guide surface forms a smoothly transitioning wedge-shaped head, which can effectively separate uncultivated soil and weeds when the cutter advances, achieving smooth guidance and diversion. This significantly reduces the resistance of the cutter's advance and the impact load of the initial soil entry, improving operating efficiency and smoothness. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] The following is for reference Figures 1 to 4 The present invention will be described in further detail below.

[0029] Reference Figure 1 An anti-tangling deep-till rotary tillage tool, as one embodiment of this utility model, is made of 65Mn spring steel or similar high-strength, high-wear-resistant alloy steel in all parts of the rotary tillage tool through die forging, heat treatment and surface strengthening processes such as quenching and tempering, to ensure that it has sufficient toughness, hardness and service life.

[0030] Among them, reference Figure 1 As one embodiment of this utility model, the blade includes a mounting part 1, which contains the connection and fixing part between the blade body and the rotary tiller blade holder disc (not shown in the figure).

[0031] Reference Figure 1 and Figure 2 One end of the mounting part 1 is fixedly provided with an extension part 2. A tillage part 3 is fixedly provided on the side of the extension part 2 away from the mounting part 1. The extension part 2 is arc-shaped, and the tillage part 3 is straight. The extension direction of the tillage part 3 is adapted to the radial direction of the extension part 2. The mounting part 1 is horizontally set, and the extension direction of the mounting part 1 is adapted to the tangent of the end of the extension part 2 away from the tillage part 3.

[0032] Reference Figure 2 One corner of the cultivated section 3 on the side away from the extension section 2 is set as a right angle, and the other corner is set as a rounded corner.

[0033] The arc-shaped structure of extension 2 can effectively improve the soil processing efficiency, so that after the tillage section 3 cuts into the soil, the tilled soil can be smoothly lifted along the relatively smooth arc surface of extension 2, thus preparing for the subsequent throwing and breaking of soil. The extension direction of installation section 1 is matched with the tangent of extension 2, which to a certain extent ensures that the force transmission from the installation point to the working point of the entire tool is smoother, and can effectively reduce the structural fatigue of the entire tool.

[0034] Reference Figure 1The mounting part 1 has a mounting hole 11 on the side away from the extension part 2. The mounting hole 11 is through-hole, and there are two mounting holes 11, which are respectively located on both sides of the mounting part 1 along the width direction of the mounting hole 11. The double hole arrangement and bolt cooperation can effectively prevent the tool from rotating circumferentially and moving laterally during operation, providing reliable fixation.

[0035] Reference Figure 1 The mounting part 1 is provided with a mounting inclined surface 12 at the end away from the extension part 2. The inclination angle of the mounting inclined surface 12 is set to 30°-45°. As one embodiment of this utility model, as shown in the figure, the inclination angle of the mounting inclined surface 12 is set to 40°. In actual use, when the tool is mounted on the tool holder disk, the end of the mounting part 1 can form a tight surface contact with the surface of the tool holder disk, thereby effectively enhancing the connection rigidity and impact resistance.

[0036] Among them, reference Figure 1 Two mounting holes 11 are located at the upper and lower ends of the mounting slope 12.

[0037] As one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the mounting inclined surface 12 is set as a straight surface, and arc-shaped connecting surfaces are provided at both ends of the mounting inclined surface 12.

[0038] As another embodiment of this utility model, such as Figure 2 As shown, the mounting slope 12 is set as an arc surface, with the convex side of the arc surface facing the mounting hole 11.

[0039] Reference Figure 1 When the mounting slope 12 is set as a straight surface, the end of the mounting part 1 away from the extension part 2 is provided with a first connecting slope 4, a second connecting slope 5 and a third connecting slope 6. The bottom end of the first connecting slope 4 is connected to the bottom edge of the mounting part 1 and the top end is connected to the bottom edge of the mounting slope 12. The bottom end of the second connecting slope is connected to the top edge of the mounting slope 12. The top end of the third connecting slope is connected to the top edge of the mounting part 1 and the top end of the second connecting slope is connected to the bottom end of the third connecting slope.

[0040] Among them, reference Figure 1 A guide surface 7 is connected between the top of the second connecting slope and the bottom of the third connecting slope. The guide surface 7 is set to be arc-shaped, and the angle between the extension directions of the second connecting slope and the third connecting slope is set to an acute angle. Together with the guide surface 7, they form a smooth wedge-shaped head, which can more quickly separate the uncultivated soil and surface weeds when the cutter moves forward with the cutter shaft, realize the effective diversion and guidance of soil and weeds, and thus effectively reduce the forward resistance and the instantaneous impact load when the cutter enters the soil.

[0041] The implementation principle of the anti-tangling deep-till rotary tillage blade proposed in this embodiment of the utility model is as follows:

[0042] By designing the tillage section 3 as a straight plate and smoothly connecting it with the arc-shaped extension section 2, the hook-like structure that easily forms a tangled core at the root of the traditional curved blade is eliminated. The straight-plate tillage section 3 can effectively cut rather than hook fibrous materials, while the streamlined overall contour makes it difficult for weeds, straws, etc. to get stuck when in contact and they are quickly thrown off under the action of centrifugal force, which significantly reduces the tangling and accumulation of materials on the cutter shaft, thereby reducing the frequency of downtime for cleaning and power consumption.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
