Description

Technical Field

[0001] This utility model relates to the technical field of engineering cutting tools, and in particular to a sickle-shaped double-edged engineering blade. Background Technology

[0002] Currently, most traditional blades used in engineering cutting operations on the market have a rectangular straight-edged structure, which has the following obvious drawbacks: Mechanical design flaws: The rectangular straight blade structure does not conform to the laws of mechanical transmission during cutting operations, lacks the engineering mechanics principle of inclined plane, has high cutting resistance, and the blade and machine body are heavy, requiring the operator to apply a large force to complete the operation; Low operating efficiency: The straight blade design can only achieve effective cutting in one direction, resulting in low blade utilization during equipment operation and making it difficult to improve operating efficiency; Significant material waste: The redundant rectangular structure leads to material waste, and the straight blade is prone to wear, resulting in a short blade lifespan and high overall operating costs.

[0003] Therefore, there is an urgent need for a cutting blade that has been significantly optimized in terms of mechanical properties, operating efficiency, and material utilization to overcome the shortcomings of the aforementioned traditional technologies. Utility Model Content

[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The following description, in conjunction with the accompanying drawings, describes an embodiment of the present invention: a sickle-shaped double-edged engineering blade.

[0022] like Figures 1-3 As shown in the figure, this utility model provides a sickle-shaped double-edged engineering blade.

[0023] Example 1: Structural Details and Material Selection This utility model discloses a sickle-shaped double-edged cutting blade, the blade body 1 of which is made of high-carbon steel through a forging process. The reason for choosing high-carbon steel is that it has high hardness and wear resistance, which can maintain the sharpness of the cutting edge during long-term cutting operations, while withstanding the impact and friction on the blade, meeting the needs of high-intensity working conditions.

[0024] A mounting hole 2 is machined in the middle of the blade body 1. The mounting hole 2 is circular, and its center is precisely located on the center line of the blade body 1. This design is to ensure that the blade maintains good dynamic balance when it is installed on the rotating shaft of equipment such as engineering lawnmowers, engineering harvesters, and garden trimming equipment, so as to avoid vibration and noise during equipment operation caused by the center of gravity shift, and even affect the cutting accuracy and blade life.

[0025] At both ends of the blade body 1, a first cutting edge 3 and a second cutting edge 4 are machined. Both are sickle-shaped arc structures, and the arc curvature of the first cutting edge 3 is exactly the same as that of the second cutting edge 4. This symmetrical arc design serves two purposes: firstly, it ensures that the blade is subjected to uniform force during rotary cutting, avoiding excessive wear in certain areas due to structural asymmetry; secondly, the sickle-shaped arc contour conforms to the mechanical transmission law during vegetation cutting, guiding the blade edge to cut into the vegetation more smoothly and significantly reducing cutting resistance.

[0026] The first cutting edge 3 and the second cutting edge 4 are machined using a double-edged structure. The thickness of the cutting edge gradually decreases from the end near the blade body 1 towards the tip. Specifically, the cutting edge near the blade body 1 is thicker to ensure the structural strength of the connection between the cutting edge and the body; the thickness gradually decreases as it extends towards the tip, ultimately forming a sharp tip for quick cutting into vegetation. This double-edged design allows the blade to effectively cut through vegetation using only one cutting edge, regardless of whether it rotates clockwise or counterclockwise, greatly improving the blade's operating efficiency and time utilization.

[0027] Example 2: Usage Procedure and Operating Principle In practical applications, the operator assembles and fixes the blade of this utility model to the rotating shaft of a construction lawnmower, construction harvester, or garden pruning equipment through the mounting hole 2. After the equipment is started, the rotating shaft drives the blade body 1 to rotate at high speed, at which time the sickle-shaped double-sided cutting edges of the first cutting edge 3 and the second cutting edge 4 make circular motion accordingly.

[0028] When the blade contacts the vegetation, the sickle-like curved structure guides the blade to cut into the vegetation. Because the curved contour matches the direction of force during cutting, the resistance of the vegetation to the blade is greatly dispersed, allowing the operator to complete the cut without applying excessive force, achieving a "labor-saving" technical effect. At the same time, the double-edged design ensures that one side of the blade is always in an effective cutting state, regardless of whether the blade is rotating clockwise or counterclockwise, significantly improving work efficiency compared to traditional straight blades.

[0029] During continuous operation, the wear resistance of high-carbon steel ensures that the cutting edge will not become dull quickly. The double-edged and double-ended cutting edge design (both the first cutting edge 3 and the second cutting edge 4 can participate in cutting) ensures that the wear of the blade is evenly distributed on the four cutting surfaces of the two cutting edges, which greatly extends the overall service life of the blade, reduces material waste, and lowers the user's operating costs.

[0030] Example 3: Comparison of advantages with existing technologies Compared with traditional rectangular straight-blade cutting blades, this invention has the following significant advantages: Labor-saving: The sickle-shaped arc structure can significantly reduce cutting resistance and greatly reduce the physical exertion of operators; Efficiency: The double-edged design with double-ended blades can significantly improve the effective working time and cutting efficiency of the blade; Economic efficiency: The wear resistance of high-carbon steel combined with optimized material utilization can significantly extend the service life of the blade and significantly reduce the overall cost of use; Adaptability: Because its structure conforms to the principles of engineering mechanics, it can be adapted to various cutting scenarios such as lawn mowing, crop harvesting, and shrub clearing, making it highly practical.

[0031] In summary, the sickle-shaped double-edged engineering blade of this utility model significantly reduces cutting resistance and improves efficiency with its sickle-shaped curved blade and double-edged structure; the double-end cutting design extends service life and improves material utilization; the structure conforms to engineering mechanics, is easy to operate and adaptable to various cutting scenarios; and the overall structure is simple, easy to manufacture and install, combining practicality and economy.
