[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a disc knife type corn stubble breaking device, including a tractor 1, a fixing frame 2 is fixedly connected to one side of the bottom of the tractor 1, a plurality of motors 6 are fixedly connected to the top of the fixing frame 2, a universal joint 7 is fixedly connected to the output end of the motor 6, a connecting rod 8 is fixedly connected to one side of the universal joint 7, a connecting rod 2 10 is slidably connected to the outer wall of the connecting rod 8, a limiting rod 9 is fixedly connected to the outer wall of the connecting rod 8, the limiting rod 9 is slidably connected to the inside of the connecting rod 2 10, and the connecting rod 2 10 is fixedly connected to the outer wall of the connecting rod 8. The end is fixedly connected with a universal joint 11, one side of the universal joint 11 is fixedly connected with a rotating shaft 17, the outer wall of the rotating shaft 17 is slidably connected with a tool 5, a plurality of gears 14 are rotatably connected inside the fixed frame 2, a plurality of cylinders 15 are fixedly connected inside the fixed frame 2, a rack 16 is fixedly connected to the output end of the cylinder 15, the outer wall of the rack 16 is meshed with the outer wall of the gear 14, a rotating rod 13 is fixedly connected to one side of the gear 14, a movable block 12 is fixedly connected to one side of the rotating rod 13, and the outer wall of the rotating shaft 17 is rotatably connected to the inside of the movable block 12;

[0033] Specifically, when the device is used to break corn stubble, the motor 6 can drive the universal joint 7 to rotate, thereby driving the connecting rod 8 to rotate, and the connecting rod 8 will drive the connecting rod 10 to rotate through the limit rod 9, so that the connecting rod 10 drives the universal joint 11 to rotate, and the universal joint 11 will drive the rotating shaft 17 to rotate, thereby causing the tool 5 to rotate to break the stubble. The universal joint 7 and the universal joint 11 are convenient for the tool 5 to continue to rotate when the angle is deflected, and the connecting rod 8 drives the connecting rod 10 through the limit rod 9 to adapt to the distance change caused by the deflection of the tool 5. When the tool 5 is adjusted in angle, the cylinder 15 can drive the rack 16, and the movement of the rack 16 can drive the gear 14 to rotate, so that the gear 14 drives the movable block 12 to rotate through the rotating rod 13, thereby controlling the angle deflection of the tool 5. This design makes the device more flexible and efficient in the process of breaking corn stubble, and can adapt to different working environments and needs.

[0034] Reference Figure 3 and Figure 4, a left-right symmetrical block 20 is slidably connected inside the rotating shaft 17, and the outer wall of the block 20 is slidably connected inside the tool 5. A column 21 is fixedly connected to one side of the bottom of the block 20, and a rotating disk 25 is rotatably connected inside the rotating shaft 17. An arc groove 22 with a circular array is provided inside the rotating disk 25, and the outer wall of the column 21 is slidably connected inside the arc groove 22. A threaded rod 19 is threadedly connected inside the rotating shaft 17, and a rotating column 23 is fixedly connected to one end of the threaded rod 19. The outer wall of the rotating column 23 is slidably connected to the rotating disk 25, and the other end of the threaded rod 19 is fixedly connected to the driving block 18. A limiting assembly is arranged on the outer wall of the rotating column 23. The limiting assembly is used for the rotating column 23 to drive the rotating disk 25 to rotate and self-lock with the help of the threaded rod 19. The limiting assembly includes a limiting rod 24, one side of the limiting rod 24 is fixedly connected to the inside of the rotating column 23, and the outer wall of the limiting rod 24 is slidably connected to the inside of the rotating disk 25;

[0035] Specifically, when the tool 5 is replaced and installed, the tool 5 can be inserted into the rotating shaft 17. Then, the driving block 18 drives the threaded rod 19 to rotate, and the rotation of the threaded rod 19 drives the rotating column 23 to rotate, and at the same time, the limiting rod 24 on the outer wall of the rotating column 23 drives the rotating disk 25 to rotate. As the arc groove 22 inside the rotating disk 25 rotates, it pushes the column 21 to move. The movement of the column 21 can drive the clamping block 20 to slide out toward the outer wall of the rotating shaft 17 and clamp into the inside of the tool 5, so that the tool 5 can be fixed. This design makes the replacement and installation process of the tool 5 more convenient and efficient, and can quickly complete the replacement and fixation of the tool 5, thereby improving work efficiency.

[0036] Reference Figure 1 A control handle 3 is fixedly connected to one side of the outer wall of the tractor 1, and a seat 4 is fixedly connected to one side of the outer wall of the tractor 1;

[0037] Specifically, the device is provided with a seat 4 and a control handle 3, and a user can sit on the seat 4, so that the user can control the tractor 1 through the control handle 3, which makes it easy to drive the device to perform corn stubble breaking operations.

[0038] Working principle: When the device is used to break corn stubble, the motor 6 can drive the universal joint 7 to rotate, thereby driving the connecting rod 8 to rotate, and the connecting rod 8 will drive the connecting rod 10 to rotate through the limit rod 9, so that the connecting rod 10 drives the universal joint 11 to rotate, and the universal joint 11 will drive the rotating shaft 17 to rotate, so that the tool 5 can rotate to break the stubble. When the angle of the tool 5 is adjusted, the cylinder 15 can drive the rack 16, and the movement of the rack 16 can drive the gear 14 to rotate, so that the gear 14 drives the rotating rod 13 to rotate. When the movable block 12 rotates, the tool 5 can be controlled to deflect at an angle. When the tool 5 is replaced and installed, the tool 5 can be inserted into the rotating shaft 17, and then the driving block 18 drives the threaded rod 19 to rotate. The rotation of the threaded rod 19 can drive the rotating column 23 to rotate, and the rotating disk 25 can be driven to rotate through the limit rod 24 on the outer wall of the rotating column 23. The arc groove 22 inside the rotating disk 25 will rotate accordingly, thereby pushing the column 21, and the column 21 can drive the clamping block 20 to slide out to the outer wall of the rotating shaft 17 and clamp into the inside of the tool 5, thereby fixing the tool 5.
