Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and more specifically, to a plow blade with a drag-reducing structure. Background Technology

[0002] Plow blades are an important component of agricultural machinery, mainly used to cut, crush, and turn the soil during tilling to prepare for sowing or planting. Plow blades are usually made of high-carbon steel, alloy steel, or wear-resistant manganese steel. Some high-end models undergo heat treatment (such as quenching) to enhance hardness and wear resistance. The shape of the blade (straight, curved, L-shaped, etc.) is designed according to the operational requirements, and the cutting edge must be kept sharp to ensure efficiency.

[0003] Existing plow blades cause severe soil adhesion during tillage, leading to increased traction resistance. Traditional methods for reducing resistance include surface polishing and increasing the sharpness of the cutting edge, but these methods suffer from poor wear resistance and high costs. Therefore, we have made improvements and proposed a plow blade with a resistance-reducing structure. Utility Model Content

[0016] 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, not all, of the embodiments of this utility model.

[0017] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0018] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] like Figure 1-4 As shown, this embodiment proposes a plow blade with a drag-reducing structure, including a handle 1, a blade body 2 integrally formed on one side of the handle 1, and a drag-reducing component 3 disposed on the surface of the blade body 2. The drag reduction component 3 includes a gasket 301, a nickel-based alloy coating 302, a groove 303, a carbon fiber coating 304, a pit 305, a flow guide 306, and a wavy profile 307. A washer 301 is disposed at the screw hole of the handle 1. A nickel-based alloy coating 302 is coated on the surface of the blade 2. A groove 303 is disposed at the leading edge of the blade 2. A carbon fiber coating 304 is coated on the surface of the groove 303. A recess 305 is disposed at the middle bearing area of ​​the blade 2. A guide groove 306 is disposed at the trailing edge of the blade 2. A wavy profile 307 is disposed at the edge of the blade 2. By disposing of the washer 301 at the screw hole of the handle 1, when the handle 1 and the blade 2 are mounted on the device, the screw will contact the surface of the washer 301, thus reducing the contact between the screw and the blade. The friction between the handle 1 and the pad 301 can improve the stability of the installation of the handle 1 and the blade 2. By setting a groove 303 with a shark gill-like structure at the front edge of the blade 2, the axis of the groove 303 is arranged at an acute angle with the cutting edge of the blade 2, so that the groove 303 can guide the soil flow. By setting a hemispherical pit 305 at the bearing part in the middle of the blade 2, the pit 305 can form an air film. The nickel-based alloy coating 302 forms a transfer film during cultivation. The soil moisture retained in the pit 305 acts as a natural lubricant to protect the surface of the blade 2. By setting a V-shaped guide groove 306 at the tail edge of the blade 2, and making the opening angle of the guide groove 306 an acute angle, the guide groove 306 can promote soil discharge. The wavy contour 307 is a non-smooth structure, which can reduce the resistance between the blade 2 and the soil during use. Thus, the above structure achieves a multi-zone synergistic drag reduction effect, causing the handle 1 and the blade 2 to generate micro-vibration during tillage, reducing the interface adhesion force. In addition, the surface structure of the blade 2 also has an oil storage function, reducing the wear rate.

[0021] like Figure 2 As shown, the shim 301 is used to improve the stability of the installation of the handle 1 and the blade 2. When the handle 1 and the blade 2 are installed on the device, the screw will contact the surface of the shim 301, thus reducing the friction between the screw and the handle 1, thereby improving the stability of the installation of the handle 1 and the blade 2.

[0022] like Figure 3 As shown, the groove 303 has a shark gill-like structure and is used to guide soil flow. By setting the shark gill-like groove 303 at the leading edge of the blade 2, and arranging the axis of the groove 303 at an acute angle to the cutting edge of the blade 2, the groove 303 can guide soil flow.

[0023] like Figure 2 As shown, the recess 305 has a hemispherical structure and is used to form an air film. By setting the hemispherical recess 305 at the bearing position in the middle of the blade 2, the recess 305 can form an air film, and the soil moisture retained in the recess 305 acts as a natural lubricant.

[0024] like Figure 4 As shown, the guide groove 306 has a V-shaped structure and is used to promote soil discharge. By setting the V-shaped guide groove 306 at the tail edge of the cutter body 2, the opening angle of the guide groove 306 is an acute angle structure, thus promoting soil discharge.

[0025] like Figure 3 As shown, the wavy profile 307 is used to reduce the resistance between the blade 2 and the soil during use. Because the wavy profile 307 is a non-smooth structure, it can reduce the resistance between the blade 2 and the soil during use. This structure achieves a multi-zone synergistic drag reduction effect, causing micro-vibrations between the handle 1 and the blade 2 during tillage, reducing interfacial adhesion. Furthermore, the surface structure of the blade 2 also has an oil-retaining function, reducing wear.

[0026] like Figure 2 As shown, the nickel-based alloy coating 302 is used to protect the surface of the blade 2. During tillage, the nickel-based alloy coating 302 forms a transfer film, and the soil moisture retained in the pits 305 acts as a natural lubricant, further protecting the surface of the blade 2.

[0027] Specifically, when using a plow blade with a drag-reducing structure: First, a washer 301 is placed at the screw hole of the handle 1, so that when the handle 1 and the blade 2 are installed on the device, the screw will contact the surface of the washer 301, thus reducing the friction between the screw and the handle 1. In this way, the washer 301 can improve the stability of the installation of the handle 1 and the blade 2. By setting a shark gill-shaped groove 303 at the leading edge of the blade 2, the axis of the groove 303 is arranged at an acute angle with the cutting edge of the blade 2, thus guiding the soil flow. By setting a hemispherical pit 305 at the bearing part in the middle of the blade 2, the pit 305 can form an air film, and the nickel-based alloy coating 302 forms a transfer film during tillage. The soil moisture retained in the pit 305 acts as a natural lubricant to protect the surface of the blade 2. By setting a V-shaped guide groove 306 at the tail edge of the blade 2, and making the opening angle of the guide groove 306 an acute angle, the guide groove 306 can promote soil discharge. The wavy contour 307 is a non-smooth structure, which can reduce the resistance between the blade 2 and the soil during use. Thus, the above structure achieves a multi-zone synergistic drag reduction effect, causing the handle 1 and the blade 2 to generate micro-vibration during tillage, reducing the interface adhesion force. In addition, the surface structure of the blade 2 also has an oil storage function, reducing the wear rate.

[0028] All technical features in this embodiment can be freely combined according to actual needs.

[0029] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
