[0017] In a specific embodiment of the present invention, the rotating rod 1 serves as the rotation center of the entire tool, and is driven to rotate by an external driving device during actual operation. A threaded rack 2 is fixedly connected to the circumferential surface of the rotating rod 1, and the threaded rack 2 is used to support the spiral loosening blade 3 and keep rotating synchronously with it. The spiral loosening blade 3 is arranged at the upper end of the threaded rack 2 and rotates together with the rotating rod 1 to achieve soil loosening and powder ridge operations. A serrated cutting blade 4 is provided on the spiral outer surface of the spiral loosening blade 3. The serrated cutting blade 4 has a serrated structure distributed along the spiral direction, which can enhance the blade's ability to cut hard objects. In order to ensure the cutting and crushing ability of hard or compacted soil, a screw fixing groove 5 is provided at the upper end of the serrated cutting blade 4, and is connected with a fixed screw 6. The fixed screw 6 is fixedly connected to the upper end of the threaded frame 2. The serrated cutting blade 4 cooperates with the fixed screw 6 through the screw fixing groove 5 to achieve a fixed connection with the spiral loosening blade 3, thereby ensuring the structural stability and safety of the tool during high-speed rotation. The combined use of the spiral loosening blade 3 and the serrated cutting blade 4 improves the loosening efficiency and powder ridge quality, which is suitable for the needs of modern agricultural automated deep plowing and loosening operations.

[0018] For details, please refer to Figure 1-Figure 3 One side end of the spiral loosening blade 3 is fixedly connected with a soil breaking cone head 7.

[0019] In this embodiment, one side end of the spiral loosening blade 3 is fixedly connected with a soil-breaking cone head 7, which is located at the front end of the tool. Before entering the soil, it can penetrate and preliminarily break the soil layer, reducing the initial resistance, improving the soil entry efficiency and operation smoothness, and is especially suitable for hard surface or severely compacted land environment. For details, please refer to Figure 1-Figure 3 The upper end of the threaded frame 2 is fixedly connected to a rotating soil retaining belt 8 through a fixed screw 6. The rotating soil retaining belt 8 is arranged above the soil layer during loosening and tillage work.

[0020] In this embodiment: the upper end of the threaded frame 2 is fixedly connected to a rotating soil retaining belt 8 through a fixed screw 6. The rotating soil retaining belt 8 is arranged above the soil layer during loosening and tillage operation, and rotates synchronously with the tool to prevent soil from splashing onto other parts of the equipment or the surrounding environment during the loosening and tillage process, thereby improving the cleanliness and safety of the operation, and at the same time helping to maintain a clear field of vision in the working area, facilitating precise control of the tillage depth and travel route.

[0021] For details, please refer to Figure 1-Figure 3 The inclination angle of the raised portion of the serrated cutting blade 4 is 30°.

[0022] In this embodiment: the inclination angle of the raised part of the serrated cutting blade 4 is 30°, which can effectively reduce the resistance of the tool in the process of cutting into the soil while ensuring sufficient cutting strength, improve crushing efficiency and energy utilization, and make it easier for the tool to cut into hard or compacted soil layers during rotation, thereby enhancing its cutting performance, reducing wear, and extending the service life of the tool. It is suitable for loosening and powder ridge operations in a variety of complex soil environments.

[0023] For details, please refer to Figure 1-Figure 3 The pitches of the threaded frame 2 and the spiral loosening blade 3 are both thirty centimeters, and the number of thread turns of the spiral loosening blade 3 is one turn.

[0024] In this embodiment: the structural design enables the spiral loosening blade 3 to plow the soil evenly during rotation, achieving a good powder ridge effect. By setting the threaded frame 2 and the spiral loosening blade 3 to the same pitch, the coordination between the two during rotation is ensured, avoiding stress concentration or unstable transmission problems caused by pitch mismatch, and improving the overall running stability and operating efficiency of the tool. At the same time, the spiral loosening blade 3 adopts a single-turn thread structure, which is convenient for processing, manufacturing, installation and maintenance, and is also conducive to controlling the tillage depth, preventing the tool from being too deeply embedded in the soil and causing excessive power loss, and is suitable for efficient deep plowing and deep loosening operations in large areas of farmland.

[0025] For details, please refer to Figure 1-Figure 3 The lower end of the rotating rod 1 is fixedly connected to a mounting bracket 9, and the mounting bracket 9 is connected to an external device mechanism.

[0026] In this embodiment: the lower end of the rotating rod 1 is fixedly connected to a mounting bracket 9, which is used to fix the entire tool device to the power output shaft or connecting mechanism of the external agricultural machinery and equipment to achieve a stable assembly between the tool and the equipment. The mounting bracket 9 can be adapted and installed according to different models of agricultural machinery, and has good interchangeability and versatility.

[0027] The working principle and use process of the present invention are as follows: the rotating rod 1 serves as the rotation center of the entire tool, and is driven to rotate by an external driving device during the actual operation process. A threaded frame 2 is fixedly connected to the circumferential surface of the rotating rod 1, and the threaded frame 2 is used to support the spiral loosening blade 3 and keep rotating synchronously with it. The spiral loosening blade 3 is arranged at the upper end of the threaded frame 2 and rotates together with the rotating rod 1 to realize the loosening and powder ridge operation of the soil. A serrated cutting blade 4 is provided on the spiral outer surface of the spiral loosening blade 3. The serrated cutting blade 4 has a serrated structure distributed along the spiral direction, which can enhance the blade's effect on the soil. In order to ensure the cutting and crushing ability of hard or compacted soil, a screw fixing groove 5 is opened at the upper end of the serrated cutting blade 4, and is connected with the fixed screw 6. The fixed screw 6 is fixedly connected to the upper end of the threaded frame 2. The serrated cutting blade 4 cooperates with the fixed screw 6 through the screw fixing groove 5 to achieve a fixed connection with the spiral loosening blade 3, thereby ensuring the structural stability and safety of the tool during high-speed rotation. The combined use of the spiral loosening blade 3 and the serrated cutting blade 4 improves the loosening efficiency and powder ridge quality, which is suitable for the needs of modern agricultural automated deep plowing and loosening operations.
