Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] Please refer to Figures 1-3 A plow frame stretching tractor, comprising a tractor body 1, a fixed frame 21 is fixedly connected to the rear side of the tractor body 1, a stretching assembly is arranged at the rear part of the tractor body 1, and a rotating plate 9 is arranged at the rear side of the tractor body 1, the stretching assembly adjusts the angle of the plow frame through the rotating plate 9; the tractor body 1 is the core carrier of the whole device and provides power and support for subsequent components. The fixed frame 21, as an important connecting and supporting structure, is stably installed at the rear side of the tractor body 1. When the angle of the plow frame needs to be adjusted, the stretching assembly starts to play a role. The stretching assembly is connected with the plow frame through the rotating plate 9, and the rotating plate 9 is driven to rotate by using a motor, a threaded rod and other structures, so that the angle of the plow frame is adjusted.

[0022] A cylinder 2 is fixedly connected to the top of the fixed frame 21, a lifting rod 3 is fixedly connected to the output end of the cylinder 2, and a lifting plate 13 is fixedly connected to the side wall of the lifting rod 3; the cylinder 2 at the top of the fixed frame 21 is the power source for adjusting the height of the plow frame. When the cylinder 2 is started, its output end is extended or retracted, driving the lifting rod 3 fixedly connected thereto to perform lifting movement. The lifting plate 13 fixed to the side wall of the lifting rod 3 also moves up and down, thereby providing a basis for subsequent lifting of the plow frame.

[0023] The lifting plate 13 is slidably connected to the side wall of the fixed frame 21; the lifting plate 13 is driven by the lifting rod 3 to slide along the side wall of the fixed frame 21. This sliding connection mode ensures the stability of the lifting plate 13 during lifting, so that it can smoothly drive the mounting frame 4 and the plow frame connected thereto to lift.

[0024] The stretching assembly further comprises a motor 5, a threaded rod 6, a mounting frame 4, a moving block 7 and a connecting strip 8. The mounting frame 4 is fixedly connected to the outer wall of the lifting plate 13. The motor 5 is fixedly connected to the top of the mounting frame 4. The threaded rod 6 is fixedly connected to the output end of the motor 5 and rotatably connected to the inner wall of the mounting frame 4. The inner wall of the moving block 7 is threadedly connected to the outer wall of the threaded rod 6 and slidably connected to the inner wall of the mounting frame 4. One end of the rotating plate 9 is movably hinged to the side wall of the lifting plate 13. The connecting strip 8 is movably hinged between the side wall of the rotating plate 9 and the moving block 7. When the angle of the plow frame needs to be adjusted, the motor 5 is started, and the output end of the motor 5 drives the threaded rod 6 to rotate. Since the inner wall of the moving block 7 is threadedly connected to the outer wall of the threaded rod 6 and slides on the inner wall of the mounting frame 4, the rotation of the threaded rod 6 drives the moving block 7 to move on the mounting frame 4. During the movement of the moving block 7, the connecting strip 8 pushes the rotating plate 9 to rotate around the hinged point of the rotating plate 9 and the lifting plate 13, so as to freely adjust the angle of the plow frame.

[0025] The side of the rotating plate 9 away from the connecting strip 8 is fixedly connected with a mounting plate 10, and the mounting plate 10 is provided with two groups. The mounting plate 10 is provided with a mounting groove 11. The mounting plate 10 is provided with a threaded hole 12. One end of the plow frame is aligned with the mounting groove 11 on the mounting plate 10, and then the plow frame is stably mounted on the mounting plate 10 by using the threaded hole 12 on the mounting plate 10 and using bolts or other connecting members.

[0026] Structure description: tractor body 1: as the core body of the whole plow frame stretching tractor, it is the key part of power supply and control. It carries the engine, driving control system, etc., provides power support for the running of the tractor and the operation of each component, and is also the installation basis of other structural components, carries components such as fixed frame 21, and ensures the stability and integrity of the whole equipment during field operation.

[0027] Cylinder 2: installed on the top of the fixed frame 21, it is a power device for adjusting the height of the plow frame. Through the movement of the internal piston, the output end of the cylinder 2 can be extended or retracted, thereby driving the lifting rod 3 fixedly connected thereto to move up and down, so as to adjust the height of the plow frame and meet the needs of different plowing depths.

[0028] Lifting rod 3: one end is fixedly connected to the output end of the cylinder 2 and moves up and down under the drive of the cylinder 2. Its side wall is fixedly connected to the lifting plate 13, which drives the lifting plate 13 to move synchronously during the lifting process, thereby providing lifting power for the mounting frame 4 and the plow frame connected thereto, and is a key transmission component for adjusting the height of the plow frame.

[0029] Mounting frame 4: fixedly connected to the outer wall of the lifting plate 13, it provides a mounting base for components such as the motor 5 and the threaded rod 6. It combines these components together to form a whole working structure, ensuring that the adjustment function of the angle of the plow frame can be stably realized when the motor 5 and the threaded rod 6 and other components are operating, and is an important support structure of the stretching assembly.

[0030] Motor 5: fixedly installed on the top of the mounting frame 4, is the power source of the angle adjustment of the plow frame in the stretching assembly. After the motor 5 is started, the output end outputs power, drives the threaded rod 6 fixedly connected thereto to rotate, and through the threaded transmission relationship between the threaded rod 6 and the moving block 7, converts the rotary motion of the motor into the linear motion of the moving block 7, so as to realize the adjustment control of the angle of the plow frame.

[0031] Threaded rod 6: one end is fixedly connected with the output end of the motor 5, and the other end is rotatably connected to the inner wall of the mounting frame 4. Under the drive of the motor 5, the threaded rod 6 rotates, and since it is threadedly connected with the inner wall of the moving block 7, it drives the moving block 7 to move along the axial direction of the threaded rod 6 in the inner wall of the mounting frame 4 when rotating, which is a key transmission component for realizing the angle adjustment of the plow frame, and realizes accurate displacement control through threaded transmission.

[0032] Moving block 7: the inner wall is threadedly connected with the outer wall of the threaded rod 6, and simultaneously slides in the inner wall of the mounting frame 4. When the threaded rod 6 rotates, the moving block 7 moves in the mounting frame 4 along with the rotation of the threaded rod 6, and its movement pushes the rotating plate 9 to rotate around the hinge point with the lifting plate 13, so as to realize the adjustment of the angle of the plow frame, which is a key execution component for realizing the angle adjustment in the stretching assembly.

[0033] Connecting strip 8: both ends are movably hinged between the side wall of the rotating plate 9 and the moving block 7, and plays a role in transmitting force and motion. When the moving block 7 moves in the mounting frame 4, the connecting strip 8 changes the angle along with the movement of the moving block 7, and then pushes the rotating plate 9 to rotate, converts the linear motion of the moving block 7 into the rotation of the rotating plate 9, and realizes the adjustment of the angle of the plow frame.

[0034] Rotating plate 9: one end is movably hinged to the side wall of the lifting plate 13, and the other end is fixedly connected with the mounting plate 10 for mounting the plow frame. Under the pushing of the connecting strip 8, the rotating plate 9 rotates around the hinge point with the lifting plate 13, thereby driving the plow frame mounted thereon to adjust the angle. At the same time, the rotating plate 9 also participates in the adjustment process of the height of the plow frame, and rises and falls along with the lifting plate 13.

[0035] Mounting plate 10: fixedly connected to the side of the rotating plate 9 away from the connecting strip 8, and provided with two groups, mainly used for mounting the plow frame. The mounting groove 11 and the threaded hole 12 provided on the mounting plate 10 provide a positioning and fixing mode for the installation of the plow frame, so that the plow frame can be stably connected with the rotating plate 9 after installation, and will not be loose or displaced during the operation of the tractor.

[0036] Mounting slot 11: Opened on the mounting plate 10, matched with the end of the plow frame. When mounting the plow frame, the end of the plow frame is inserted into the mounting slot 11, which can preliminarily fix the position of the plow frame, providing accurate positioning for subsequent fastening through the threaded hole 12, improving the accuracy and convenience of plow frame installation.

[0037] Threaded hole 12: Located on the mounting plate 10, used to cooperate with connecting components such as bolts. After the end of the plow frame is inserted into the mounting slot 11 for preliminary positioning, the plow frame is firmly fixed on the mounting plate 10 by the bolt passing through the threaded hole 12, ensuring that the plow frame is tightly connected with the rotating plate 9 during the operation of the tractor, and will not loosen, ensuring the smooth progress of the plowing operation.

[0038] Lifting plate 13: The side wall is fixedly connected with the lifting rod 3, and is driven by the lifting rod 3 to slide along the side wall of the fixed frame 21. The lifting plate 13 not only carries the mounting frame 4 and the motor 5, threaded rod 6 and other components on the mounting frame 4, but also connects with the plow frame through the rotating plate 9, realizing the height adjustment of the plow frame. At the same time, it is also the support basis for the rotation of the rotating plate 9, providing a stable platform for the angle adjustment of the plow frame.

[0039] Fixed frame 21: Stably installed on the rear side of the tractor body 1, it is an important supporting component of the entire plow frame adjustment structure. Its top part provides a mounting base for the air cylinder 2, and its side wall provides a sliding track for the lifting plate 13, ensuring the stability of the lifting plate 13 during lifting, and ensuring the smooth progress of the height adjustment and angle adjustment of the plow frame.

[0040] Usage instructions

[0041] Align the end of the plow frame with the mounting slot 11 on the mounting plate 10, then use the threaded hole 12 on the mounting plate 10 and connecting components such as bolts to firmly install the plow frame on the mounting plate 10. When adjusting the angle of the plow frame, start the motor 5, and the output end of the motor 5 drives the threaded rod 6 to rotate. Because the inner wall of the moving block 7 is threadedly connected with the outer wall of the threaded rod 6 and slides in the inner wall of the mounting frame 4, the rotation of the threaded rod 6 drives the moving block 7 to move on the mounting frame 4. During the movement of the moving block 7, the connecting strip 8 pushes the rotating plate 9 to rotate around the hinge point between the rotating plate 9 and the lifting plate 13, thereby realizing the free adjustment of the angle of the plow frame. If you want to lift the height of the plow frame, start the air cylinder 2, and the output end of the air cylinder 2 drives the lifting rod 3 to perform lifting movement. The lifting plate 13 fixed on the side wall of the lifting rod 3 rises along with the lifting rod 3 along the fixed frame 21, and the lifting plate 13 drives the mounting frame 4 to rise, finally making the plow frame installed on the rotating plate 9 realize lifting.
