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 scope of protection of the present utility model.

[0027] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0028] This application discloses a three-degree-of-freedom suspension mechanism for tractor-mounted agricultural implements. (Refer to...) Figure 1-5 A three-degree-of-freedom agricultural implement suspension mechanism for a tractor includes a rotating chamber 2. The rotating chamber 2 is equipped with a disassembly / removal latch 1. The disassembly / removal latch 1 includes a latch post 11. A circular limiting plate 12 is fixedly connected to the left side of the latch post 11. A cylinder 13 is fixedly connected to the side of the circular limiting plate 12 away from the latch post 11. A spring 14 is fixedly connected to the outer side of the cylinder 13 around the side of the circular limiting plate 12 away from the latch post 11. A handle 15 is fixedly connected to the side of the cylinder 13 away from the circular limiting plate 12. The rotating chamber 2 includes a first rotating block 21. A square block 22 is fixedly connected below the first rotating block 21. A T-shaped sliding groove 23 is formed in front of the square block 22. A T-shaped circular groove 24 is formed on the lower left side of the inner wall of the T-shaped sliding groove 23. A circular hole 25 is provided on the left side of the inner wall. The inner wall of the T-shaped circular groove 24 is slidably connected to the outer wall of the locking post 11 and the circular limiting plate 12. The left side of the inner wall of the T-shaped circular groove 24 is fixedly connected to the other end of the spring 14. The inner wall of the circular hole 25 is slidably connected to the outer wall of the cylinder 13. A first plowing implement 3 is slidably connected to the inner wall of the T-shaped sliding groove 23. The first plowing implement 3 includes a second plowing implement 31. A connecting block 32 is fixedly connected to the middle of the upper part of the second plowing implement 31. A T-shaped sliding block 33 is fixedly connected to the upper part of the connecting block 32. A circular insertion hole 34 is provided on the left side of the T-shaped sliding block 33 at the position corresponding to the locking post 11. The outer wall of the T-shaped sliding block 33 is slidably connected to the inner wall of the T-shaped sliding groove 23. The inner wall of the circular insertion hole 34 is slidably connected to the outer wall of the locking post 11.

[0029] The disassembly and assembly buckle 1, in conjunction with the rotating chamber 2, allows for quick disassembly and assembly of the No. 1 plowing implement 3. During use, pulling the handle 15 causes the cylinder 13 to slide, moving the circular limiting plate 12. The circular limiting plate 12 then slides, moving the locking post 11. The locking post 11 slides and disengages from the circular insertion hole 34, placing it within the inner wall of the T-shaped groove 24. Then, moving the No. 2 plowing implement 31 forward causes the T-shaped sliding block 33 to slide and disengage from the T-shaped sliding groove 23, thus completing disassembly. During assembly, pulling the handle 15 causes the locking post 11 to slide into the T-shaped groove 24. In the inner wall of the circular groove 24, the T-shaped sliding block 33 is aligned with the T-shaped sliding groove 23 and inserted. Then, the handle 15 is released so that the spring 14 pushes the circular limiting plate 12 through elastic force. The circular limiting plate 12 slides and pushes the locking post 11. The locking post 11 slides into the circular insertion hole 34 to complete the installation. The above operations only require pulling the handle 15, which is simple and convenient. The design of the disassembly and assembly buckle 1 can greatly shorten the time for changing agricultural implements, reduce downtime, increase the amount of work per unit time, and thus improve the overall work efficiency.

[0030] Reference Figure 6 and Figure 7A first angle adjustment mechanism 4 is rotatably connected to the left and right sides of the first rotating block 21. The first angle adjustment mechanism 4 includes a second rotating block 41. A first frame 42 is fixedly connected to the lower part of the second rotating block 41. A first motor 43 is fixedly connected to the left side of the first frame 42. The inner walls of the left and right sides of the first frame 42 are rotatably connected to the left and right sides of the first rotating block 21. The output end of the first motor 43 is fixedly connected to the left side of the first rotating block 21. A second angle adjustment mechanism 5 is rotatably connected to the front and rear sides of the second rotating block 41. The second angle adjustment mechanism 5 includes a second frame 51. The front of the second frame 51 is fixedly connected to the second angle adjustment mechanism 5. A second motor 52 is connected. The inner walls of the front and rear sides of the second frame 51 are rotatably connected to the front sides of the second rotating block 41. The output end of the second motor 52 is fixedly connected to the front of the second rotating block 41. A third angle adjustment mechanism 6 is fixedly connected above the second frame 51. The third angle adjustment mechanism 6 includes a support arm 61. The left and right sides of the upper rear of the support arm 61 are rotatably connected to the third frame 62. A third motor 63 is fixedly connected to the right side of the third frame 62. A mounting plate 64 is fixedly connected to the rear of the third frame 62. The side of the support arm 61 away from the mounting plate 64 is fixedly connected to the top of the second frame 51.

[0031] The No. 1 angle adjustment mechanism 4, the No. 2 angle adjustment mechanism 5, and the No. 3 angle adjustment mechanism 6 work together to allow the No. 1 plowing implement 3 to be adjusted at multiple angles. In use, the No. 1 motor 43 drives the No. 1 rotating block 21 to rotate, which allows the No. 1 plowing implement 3 to tilt forward and backward. The No. 2 motor 52 drives the No. 2 rotating block 41 to rotate, which allows the No. 1 plowing implement 3 to tilt left and right. The No. 3 motor 63 drives the support arm 61 to rotate, which allows the No. 1 plowing implement 3 to lift up and down. Through the three-degree-of-freedom control of the No. 1 angle adjustment mechanism 4, the No. 2 angle adjustment mechanism 5, and the No. 3 angle adjustment mechanism 6, the height, pitch, and tilt angles of the plowing implement can be dynamically adjusted in real time, so that it always maintains the best working state with the ground, effectively avoiding problems such as missed plowing, double plowing, or inconsistent plowing depth.

[0032] Working principle: The disassembly and assembly buckle 1, in conjunction with the rotating chamber 2, allows for quick disassembly and assembly of the No. 1 plowing implement 3. During use, pulling the handle 15 causes the cylinder 13 to slide, moving the circular limiting plate 12. The circular limiting plate 12 then slides, moving the locking post 11. The locking post 11 slides and disengages from the circular insertion hole 34, placing it within the inner wall of the T-shaped groove 24. Then, moving the No. 2 plowing implement 31 forward causes the T-shaped sliding block 33 to slide and disengage from the T-shaped sliding groove 23, completing the disassembly. During installation, pulling the handle 15 causes the locking post 11 to slide and disengage. The T-shaped sliding block 33 is inserted into the T-shaped sliding groove 23 within the inner wall of the T-shaped groove 24. Then, the handle 15 is released so that the spring 14 pushes the circular limiting plate 12 through its elastic force. The circular limiting plate 12 slides and pushes the locking post 11. The locking post 11 slides into the circular insertion hole 34 to complete the installation. The above operations only require pulling the handle 15, which is simple and convenient. The design of the disassembly and assembly buckle 1 can greatly shorten the time for changing agricultural implements, reduce downtime, and increase the amount of work per unit time, thereby improving the overall work efficiency.

[0033] The No. 1 angle adjustment mechanism 4, the No. 2 angle adjustment mechanism 5, and the No. 3 angle adjustment mechanism 6 work together to allow the No. 1 plowing implement 3 to be adjusted at multiple angles. In use, the No. 1 motor 43 drives the No. 1 rotating block 21 to rotate, which allows the No. 1 plowing implement 3 to tilt forward and backward. The No. 2 motor 52 drives the No. 2 rotating block 41 to rotate, which allows the No. 1 plowing implement 3 to tilt left and right. The No. 3 motor 63 drives the support arm 61 to rotate, which allows the No. 1 plowing implement 3 to lift up and down. Through the three-degree-of-freedom control of the No. 1 angle adjustment mechanism 4, the No. 2 angle adjustment mechanism 5, and the No. 3 angle adjustment mechanism 6, the height, pitch, and tilt angles of the plowing implement can be dynamically adjusted in real time, so that it always maintains the best working state with the ground, effectively avoiding problems such as missed plowing, double plowing, or inconsistent plowing depth.
