[0019] Figure 4 is a front view of the embodiment 3 of the present application. DETAILED DESCRIPTION
[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.
[0021] In the description of the embodiments of the present application, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship of the product of the present application when it is usually placed, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third" and the like are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.
[0022] In addition, if the terms "horizontal", "vertical", "overhanging" and the like are used, it does not mean that the components must be absolutely horizontal or overhanging, but can be slightly inclined. For example, "horizontal" only means that it is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.
[0023] As shown in the drawings, the agricultural machinery anti-winding blade comprises a blade 100, which comprises an integrally formed blade handle 101 and a blade body 102. The integrally formed design ensures the integrity and stability of the blade structure, reducing the risk of failure caused by loose connection during high-intensity operation.
[0024] The two sides of the blade body 102 are a blade back 103 and a blade edge 104, respectively, and the end of the blade body 102 away from the blade handle 101 is a blade edge 105. The blade back 103 and the blade edge 104 are both curved inwardly to the inside of the blade body 102, and the curvature of the blade back 103 is greater than that of the blade edge 104. The unique curved design of the blade back and the blade edge is one of the key innovations of the present application. When the blade rotates at high speed for cutting, the inwardly curved blade back and blade edge can guide the cut material to slide along the curved surface, rather than winding around the blade body. The blade back with a larger curvature plays a major role in diverting and blocking the winding material, while the blade edge assists in cutting and cooperates with the blade back to prevent winding, and the blade edge 105 at the end ensures omnidirectional cutting effect, so that the blade can maintain high efficiency and be less likely to be wound when facing complex cutting scenarios of crop straw, weeds and the like.
[0025] The blade body 102 is in the shape of an upper roll. The upper roll design of the blade body further optimizes the flow direction of the material during cutting, making it easier for the cut material to be thrown upward, reducing the possibility of accumulation and winding under the blade body, and also enhancing the adaptability of the blade to crops of different heights, whether it is low pasture or higher straw crops, smooth cutting can be achieved.
[0026] The inner side of the blade handle 101 is provided with a notch 106. The notch can reduce the overall weight of the blade, in line with the development trend of lightweight agricultural machinery, and reduce energy consumption. On the other hand, during installation, the notch can better fit the mechanical connection part, enhancing the stability of the installation and preventing displacement of the blade during high-speed operation.
[0027] The blade handle 101 is provided with a mounting hole 107. Through the mounting hole, the blade can be conveniently and quickly fixed to the rotating shaft or cutter disc of the agricultural machinery, and the installation angle and spacing of the blade can be flexibly adjusted according to different mechanical models and operation needs, realizing diversified cutting configuration.
[0028] The cutter comprises three groups of blades 100, which are fixedly connected in a ring array. The ring array combination of multiple groups of blades greatly improves the single cutting area and efficiency, and can quickly complete the task in large-area farmland harvesting or forage processing operation. At the same time, the blades cooperate with each other, the airflow generated during rotary cutting can further blow away the possible entangled sundries, and the complementary cutting tracks can maximize the avoidance of cutting dead angles, thereby ensuring the integrity of the cutting operation.
[0029] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
