Technical Field
[0001] This utility model relates to the field of agricultural technology, specifically to an energy-saving vibratory deep tillage machine. Background Technology
[0002] Vibratory subsoilers are key equipment in the agricultural field used to break up the plow pan and improve soil aeration and water retention capacity. Their performance is closely related to their core connection structure and vibration adaptability.
[0003] However, in the connection structure between the subsoil shovel and the main frame, traditional equipment mostly adopts a single thread connection. Since the subsoiler will generate high-frequency vibration during operation, long-term vibration can easily lead to the attenuation of friction between threads and wear of thread profiles, resulting in loose connection problems. Therefore, an energy-saving vibratory subsoiler is proposed to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an energy-saving vibratory deep loosening machine that can counteract the impact of vibration on the connection. This solves the problem that long-term vibration can easily lead to attenuation of friction between threads, wear of thread profiles, and consequently, loosening of the connection.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving vibratory deep loosening machine, including a support rod, a threaded hole at the top of the support rod, a connecting block fixedly connected to the outside of the support rod, a support block inside the connecting block, a circular groove inside the support block, and a shock-absorbing and fixing structure inside the circular groove; The shock-absorbing and fixing structure includes an outer cylinder that contacts a circular groove.

[0009] Preferably, the support block has a fixing groove inside, which is adapted to the ball bearing, and a baffle is fixedly connected inside the fixing hole, which is adapted to the ball bearing.
[0010] Preferably, a first spring is fixedly connected inside the connecting block, the first spring is fixedly connected to the support block, a limit block is fixedly connected to the outside of the support block, a limit groove is formed inside the connecting block, and the limit block is engaged inside the limit groove.
[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects: This energy-saving vibratory subsoiler features an outer cylinder that penetrates the top of the subsoil shovel and extends into the circular groove of the support block, achieving precise positioning between the shovel and the support block and preventing lateral displacement of the shovel during vibration operation. A threaded connection between the rotating rod and the outer cylinder, a bearing on the bottom wall of the outer cylinder, and a second spring and locking block connected to the bottom of the rotating rod ensure precise transmission of driving force and axial directional movement of the locking block, providing a stable power foundation for subsequent fixing.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-4 An energy-saving vibratory deep loosening machine in this embodiment includes a support rod 1, a threaded hole 2 at the top of the support rod 1, a connecting block 3 fixedly connected to the outside of the support rod 1, a support block 7 inside the connecting block 3, a circular groove 701 inside the support block 7, and a shock-absorbing fixing structure 9 inside the circular groove 701. The shock-absorbing and fixing structure 9 includes an outer cylinder 901, which is in contact with a circular groove 701. A rotating rod 902 is provided inside the outer cylinder 901. A second spring 903 is fixedly connected to the bottom of the rotating rod 902. A locking block 904 is fixedly connected to the bottom of the second spring 903. A fixing hole 907 is provided inside the outer cylinder 901. A ball bearing 906 is provided inside the fixing hole 907.
[0016] A deep loosening shovel 8 is provided on the outside of the support block 7. A round hole is opened at the top of the deep loosening shovel 8, and the outer cylinder 901 extends through this hole into the circular groove 701, which builds a stable connection bridge between the deep loosening shovel 8 and the support block 7. By the outer cylinder 901 passing through the round hole at the top of the deep loosening shovel 8 and extending into the circular groove 701 of the support block 7, the deep loosening shovel 8 can be accurately positioned outside the support block 7, avoiding lateral displacement of the deep loosening shovel 8 during vibration operation. At the same time, it lays the foundation for the subsequent use of the shock-absorbing fixing structure 9 to achieve stable fixation and shock absorption of the deep loosening shovel 8, ensuring that the deep loosening shovel 8 always maintains the correct working posture during soil tillage.
[0017] The rotating rod 902 has an external thread, and the inner wall of the outer cylinder 901 has an internal thread. The rotating rod 902 and the outer cylinder 901 are connected by threads. The inner bottom wall of the outer cylinder 901 is fixedly connected to a bearing 905. The bottom of the locking block 904 is fixedly connected to the inner ring of the bearing 905, providing an adjustable driving force transmission path for the vibration damping and fixing structure 9. Through the threaded connection between the rotating rod 902 and the outer cylinder 901, the axial movement of the rotating rod 902 within the outer cylinder 901 can be precisely controlled when rotating. Then, the locking block 904 is pushed by the second spring 903. The bearing 905 prevents the locking block 904 from rotating synchronously with the rotating rod 902, ensuring that the locking block 904 can only move axially, preparing for the subsequent pushing of the ball 906 to achieve fixation. At the same time, the threaded connection design also provides a foundation for the initial fixation of the structure, working together with subsequent components to cope with the vibration environment.
[0018] The bottom of the locking block 904 is trapezoidal, narrow at the bottom and wide at the top. The locking block 904 contacts the ball 906, optimizing the force transmission of the locking block 904 to the ball 906. When the trapezoidal locking block 904 moves axially with the rotating rod 902, it can apply radial thrust to the ball 906 smoothly and evenly using the inclined surface. This avoids the situation where the ball 906 is stuck or damaged due to uneven force caused by the unreasonable shape of the bottom of the locking block 904. It ensures that the ball 906 can smoothly pop out from the fixing hole 907 and lock into the fixing groove 702, providing a key force transmission guarantee for the stable fixation of the vibration damping fixing structure 9 and helping to solve the fixation problem in the vibration environment.
[0019] The support block 7 has a fixing groove 702 inside, which is adapted to the ball 906. A baffle 908 is fixedly connected inside the fixing hole 907, which is adapted to the ball 906, providing a precise fixed position and movement restriction for the ball 906. The fixing groove 702 can engage and limit the ball 906 after it is pushed out, so that the outer cylinder 901 and the support block 7 form a stable connection, thereby fixing the deep loosening shovel 8. The baffle 908 can prevent the ball 906 from falling out of the fixing hole 907 when it is not pushed, and at the same time, it plays a guiding role when the ball 906 is pushed and moves, ensuring that the ball 906 can accurately enter the fixing groove 702. Together with other components, it forms a reliable fixing structure, enhances the stability of the shock-absorbing fixing structure 9 in the vibration environment, and avoids loosening of the connection.
[0020] A first spring 6 is fixedly connected inside the connecting block 3. The first spring 6 is fixedly connected to the support block 7. A limit block 5 is fixedly connected to the outside of the support block 7. A limit groove 4 is opened inside the connecting block 3. The limit block 5 is engaged inside the limit groove 4, providing buffering, shock absorption and movement limitation for the support block 7. The first spring 6 can absorb part of the vibration energy transmitted to the support block 7 when the deep tillage machine is vibrating, reducing the rigid collision between the support block 7 and the connecting block 3 and reducing vibration damage to the overall structure. The engagement of the limit block 5 and the limit groove 4 can limit the movement range of the support block 7 within the connecting block 3, preventing the support block 7 from being excessively displaced due to vibration and affecting the working position of the deep tillage shovel 8. At the same time, it works in synergy with the first spring 6 to further improve the stability of the entire device in a vibration environment and help the shock absorption and fixing structure 9 to better solve the problem of loose threads.
[0021] When implementing this procedure, please follow these steps: 1) First, fix the support rod 1 to the main frame of the deep tillage machine through the threaded hole 2 at the top. Then, align the support block 7 with the limiting groove 4 inside the connecting block 3 through the external limiting block 5, so that the support block 7 and the first spring 6 inside the connecting block 3 form a fixed connection, and complete the assembly of the basic frame of the device. 2) Then align the deep loosening shovel 8 with the outer position of the support block 7, so that the round hole at the top of the deep loosening shovel 8 is aligned with the round groove 701 of the support block 7. Then, insert the outer cylinder 901 of the shock-absorbing fixing structure 9 through the round hole of the deep loosening shovel 8 and into the round groove 701 to initially achieve the positioning of the deep loosening shovel 8 and the support block 7. 3) Rotate the rotating rod 902 of the shock-absorbing fixing structure 9 again. Utilize the threaded connection between the rotating rod 902 and the outer cylinder 901 to push the second spring 903 and the locking block 904 at the bottom of the rotating rod 902 to move the bearing 905 axially. Ensure that the locking block 904 does not rotate with the rotating rod 902. This allows the trapezoidal locking block 904 to apply radial thrust to the ball 906, pushing the ball 906 through the fixing hole 907 and locking it into the fixing groove 702 of the support block 7, thus completing the stable fixing of the deep loosening shovel 8. 4) Finally, start the subsoiler. During the vibration operation, the first spring 6 absorbs part of the vibration energy, the limit block 5 and the limit groove 4 limit the offset of the support block 7, and the shock absorption and fixing structure 9 prevents the connection from loosening through a combination of thread, mechanical engagement and spring buffer, ensuring that the subsoiler shovel 8 maintains the correct working posture and completes the soil subsoil operation. After the operation is completed, rotate the rotating rod 902 in the opposite direction to reset the locking block 904 and disengage the ball 906 from the fixing groove 702, so that the subsoiler shovel 8 can be disassembled for maintenance or replacement.
[0022] In summary, this energy-saving vibratory subsoiler achieves precise positioning of the subsoiler 8 and the support block 7 by setting an outer cylinder 901 that penetrates the top circular hole of the subsoiler 8 and extends into the circular groove 701 of the support block 7, thus preventing lateral displacement of the subsoiler 8 during vibration operation. The threaded connection between the rotating rod 902 and the outer cylinder 901, the bearing 905 on the inner bottom wall of the outer cylinder 901, and the second spring 903 and locking block 904 connected to the bottom of the rotating rod 902 ensure precise transmission of driving force and axial directional movement of the locking block 904, providing a stable power foundation for subsequent fixing. The trapezoidal locking block 904 at its bottom engages with the ball bearing 906, providing uniform radial thrust to the ball bearing 906 and ensuring smooth engagement of the ball bearing 906. The fixing groove 702 of the support block 7 further enhances its performance. The baffle 908 inside the fixing hole 907 ensures precise fixing and prevents the ball bearing 906 from falling off, enhancing the vibration stability of the shock-absorbing fixing structure 9. By setting the first spring 6 inside the connecting block 3, the limiting block 5 outside the support block 7, and the limiting groove 4 of the connecting block 3, the support block 7 achieves buffering and shock absorption and movement limitation, reducing vibration damage. Finally, the shock-absorbing fixing structure 9, composed of the outer cylinder 901, rotating rod 902, second spring 903, locking block 904, bearing 905, ball bearing 906, fixing hole 907, and baffle 908, effectively solves the problem of traditional threaded fixing being prone to loosening in a vibrating environment, ensuring the stability of the connection structure during long-term vibration operation of the subsoiler, while ensuring that the subsoil shovel 8 always maintains the correct working posture, improving soil tillage efficiency and quality.
