Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil loosening devices, and in particular to a soil loosening device for improving farmland soil fertility. Background Technology
[0002] In modern agricultural production, soil fertilization is a crucial step in improving crop yield and quality. After long-term cultivation, soil is prone to compaction and poor aeration, hindering crop root growth and nutrient absorption. Soil loosening devices can break up compacted layers, increase soil porosity, and promote the penetration and diffusion of air, water, and fertilizers, creating a favorable soil environment for crop growth. Therefore, soil loosening devices play a vital role in farmland soil fertilization.
[0003] Currently, most common farmland soil loosening devices on the market adopt a roller structure, which breaks and loosens the soil through the teeth on the roller. However, during the loosening process, soil will adhere to the teeth on the outer wall of the loosening roller. As the soil accumulates, it will not only reduce the rotation efficiency of the loosening roller, but also affect the quality of loosening, resulting in uneven soil loosening. In view of this technical problem, this application proposes a loosening device for farmland soil fertilization. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a soil loosening device for farmland soil improvement. During soil loosening operations, the insert teeth effectively remove soil adhering to the teeth of the loosening roller, preventing soil accumulation. Through continuous cleaning, the loosening roller teeth are kept clean, allowing it to fully perform its loosening function, ensuring uniform and thorough soil loosening, and effectively improving the quality and efficiency of soil loosening operations. When the insert teeth are worn and require maintenance or replacement, simply push the pull rod upwards. The pull rod drives the top plate, which in turn pushes the two limiting plates to both sides of the insertion block, allowing the insert teeth to be quickly removed from the fixed seat. When installing a new insert tooth, align its front insertion groove with the insertion block. During installation, the insertion block automatically pushes open the limiting plates and compresses the spring. When the top of the limiting plate moves into the recesses on both sides of the insertion block, the spring pushes out the limiting plate, thus facilitating the maintenance and replacement of the insert teeth by the workers.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A soil loosening device for improving farmland soil fertility includes a mounting plate. A fixed frame is rotatably connected to the bottom front end of the mounting plate. An electric telescopic rod is rotatably connected to the top front end of the fixed frame.

[0008] Furthermore, the limiting component includes a insertion groove located at the front end of the insert tooth, a limiting plate rotatably connected to the inner wall of the insertion groove, a spring provided on the outer wall of the limiting plate, one end of the spring being connected to the outer wall of the limiting plate, and the other end of the spring being connected to the inner wall of the insertion groove of the insert tooth.
[0009] Furthermore, support blocks are fixedly connected to both ends of the rotating rod, and the bottom front end of the fixing frame is fixedly connected to the support blocks. A housing is fixedly connected to the opposite side of the two support blocks. A spring is provided on the inner wall of the housing. One end of the spring is connected to the rotating rod, and the other end of the spring is connected to the inner wall of the housing.
[0010] Furthermore, a limit block is provided on the inner wall of the rotating ring at the right end.
[0011] Furthermore, protrusions are fixedly connected to the outer walls of the left and right ends of the rotating rod and to the adjacent side of the two support blocks.
[0012] Furthermore, the soil loosening roller has an installation groove in the middle that matches the size of the insertion rod.

The other end of the electric telescopic rod 2 is rotatably connected to the top front end of the mounting plate 1. The angle of the fixing frame 3 can be adjusted by the electric telescopic rod 2, thereby adjusting the position of the loosening roller 5. A connecting block 4 is fixedly connected to the bottom end of the fixing frame 3, and a rotating ring is rotatably connected to the inner wall of the bottom end of the connecting block 4. An insertion rod 8 is provided on the adjacent side of the two connecting blocks 4, and the loosening roller 5 is sleeved on the outer wall of the insertion rod 8. The loosening roller 5 can be installed by inserting the insertion rod 8 into the mounting groove in the middle of the rotating ring and the loosening roller 5. A rotating rod 9 is provided at the bottom front end of the fixing frame 3, and a fixing rod 9 is fixedly connected to the outer wall of the rotating rod 9. The base 10 is fixedly connected to the rear end of the fixed base 10 and the plug block 15. The plug block 15 has recesses on both sides. By rotating the top of the limiting plate 13 into the recess, the plug tooth 11 can be limited. The bottom end of the plug block 15 is slidably connected to the pull rod 16. The top end of the pull rod 16 is fixedly connected to the top plate 17. By pulling the pull rod 16, the top plate 17 can be moved. When the top plate 17 moves upward, it can push the two limiting plates 13 to both sides of the plug block 15, thereby disassembling the plug tooth 11. The front end of the plug tooth 11 has a plug groove. The inner wall of the plug groove is rotatably connected to the limiting plate 13. The outer wall of the limiting plate 13 is provided with a spring 14. One end of the spring 14 is connected to the outer wall of the limiting plate 13, and the other end of the spring 14 is connected to the inner wall of the plug groove of the plug tooth 11. The spring 14 can push the limiting plate 13 into the recesses on both sides of the plug block 15.
[0026] Reference Figures 4-6 The rotating rod 9 has support blocks fixedly connected to both ends. These support blocks are fixedly connected to the bottom front end of the fixing frame 3. A housing 6 is fixedly connected to the opposite side of each support block. A spring 12 is installed on the inner wall of the housing 6. One end of the spring 12 is connected to the rotating rod 9, and the other end is connected to the inner wall of the housing 6. The spring 12 allows the rear end of the insert tooth 11 to contact the outer wall of the loosening roller 5, thus shoveling the soil adhering between the teeth of the loosening roller 5. A limit block 7 is installed on the inner wall of the right rotating ring, and the inner wall of the right rotating ring and the outer wall of the limit block 7 are provided with matching threads. Protrusions are fixedly connected to the outer walls of both ends of the rotating rod 9 and the adjacent sides of the two support blocks. These protrusions limit the rotation angle of the rotating rod 9, preventing excessive rotation of the insert tooth 11.

The limiting block 7 is then screwed into the rotating ring to limit the position of the insert rod 8, thus ensuring the stability of the loosening roller 5. During the loosening process, when soil adheres between the teeth of the loosening roller 5, the insert teeth 11 can scoop away the soil, preventing it from adhering to the teeth and ensuring the quality of loosening. When maintenance or replacement of the insert teeth 11 is required, the pull rod 16 is pushed upwards, allowing the top plate 17 to move towards... The top plate 17 pushes the two limiting plates 13 towards the sides of the insertion block 15, thereby allowing the insertion teeth 11 to be removed from the fixed seat 10. When installing the insertion teeth 11, the insertion groove at the front end of the insertion teeth 11 is installed onto the insertion block 15. During the installation process, the insertion block 15 first pushes the limiting plates 13 towards the sides of the insertion block 15 and compresses the spring 14. When the top of the limiting plate 13 moves into the recesses on both sides of the insertion block 15, the spring 14 can push the limiting plate 13 out of the recesses on both sides of the insertion block 15, thereby stably connecting the insertion teeth 11 with the fixed seat 10 and preventing the insertion teeth 11 from loosening during operation.
