Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and in particular relates to an adjustable plowing device. Background Technology

[0002] A plow is an agricultural implement used for tilling the land. It consists of a heavy blade at the end of a crossbeam and is usually attached to a group of animals or motor vehicles that pull it. Some plows are also driven by human power. Plows can break up clods of soil and create furrows to prepare for sowing. There are several types of plows, including moldboard plows, disc plows, and rotary plows. With the advancement of human technology, the structure of plows has been constantly changing, gradually moving towards greater convenience and better results.

[0003] For example, patent number CN218941678U discloses an angle-adjustable plowing device, including a plowing device and a connecting device. The key feature is that an angle adjustment device is provided between the plowing device and the connecting device. The angle adjustment device includes a connector and an adjusting screw. The bottom of the connector is connected to the plowing device, the middle part is connected to the connecting device, and one side of the connector is movably connected to the plowing device via the adjusting screw. This utility model provides an angle adjustment device between the plowing device and the connecting device, thereby adjusting the plowing angle of the plowing harrow teeth as needed, avoiding phenomena such as seedling crushing and clod formation. Furthermore, this structure promotes soil loosening, allowing crop roots to grow better and more developed.

[0004] In existing technologies, by setting an adjusting screw and connecting device, the angle of plowing can be changed, avoiding the phenomena of crushing seedlings and creating clumps. However, the following problems still exist in the overall use: First, the angle that the plow blades of existing technologies can change is very limited. When cultivating areas with obstacles such as fruit trees or field edges, the plow frame cannot be adjusted, which increases the difficulty of the work and reduces work efficiency. Second, there are buried stones in the cultivated field, which can damage the plow blades during cultivation and affect the plowing effect. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides an adjustable plowing device. By setting an adjustment frame and a rotatable mounting frame, the tilt angle of the plow blade can be changed to avoid obstacles. The distance between the plow blade and the vehicle body can also be adjusted to adapt to the conditions of the cultivated land, thereby improving the flexibility of the device. By setting a cleaning component, stones buried in the soil can be removed to prevent them from damaging the plow blade and extend its service life, thus improving the plowing effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable plowing device, comprising a vehicle body, a connecting frame on one side of the vehicle body, a crossbeam on one side of the connecting frame, and multiple adjusting frames on one side of the crossbeam. Each adjusting frame has a slidably mounted drive block inside. Connecting rods are rotatably mounted on both the upper and lower sides of each drive block. One end of two connecting rods is rotatably mounted with a tilting mounting bracket. A plow handle is rotatably mounted on one end of the mounting bracket, and a plow blade is mounted at the bottom of the plow handle. A cleaning component is rotatably mounted at the bottom of the connecting frame, and a buffer is rotatably mounted on one side of the cleaning component. The cleaning component can detect and clear the soil to be plowed, dislodging stones buried in the soil, making it easier for the subsequent plow blade to plow the land, thereby improving the plowing effect.

[0007] Preferably, the adjusting frame has a threaded rod rotatably mounted inside, and a movable block is provided on the surface of the threaded rod. The movable block is fixedly connected to the driving block. The movable block can drive a connecting rod on one side of the driving block to move, thereby changing the distance between the mounting frame and the crossbeam, causing the mounting frame to tilt and adjust its angle.

[0008] Preferably, two short rods are rotatably connected to each end of the crossbeam and the two connecting rods. By providing short rods, the connecting rods can rotate around the connection points of the short rods, thus providing support for the connecting rods.

[0009] Preferably, a slide rail is provided at the bottom of the threaded rod on the end face of the adjusting frame, and a limit slider is slidably provided on the surface of the slide rail, and the limit slider is fixedly connected to the driving block.

[0010] Preferably, a handle is provided on one side of the threaded rod on the surface of the adjusting frame. The handle allows for manual adjustment of the position of the drive block, facilitating changes to the angle of the mounting frame.

[0011] Preferably, a connector is rotatably mounted on the top of the connecting frame, a fixing rod is rotatably mounted on one end of the connector, and the other end of the fixing rod is rotatably connected to the plow handle. By using the connector, the plow handle can be simultaneously adjusted in angle and distance.

[0012] Preferably, the bottom of the connecting frame is provided with a locking block, the bottom of the locking block is provided with a detachable long strip, and the bottom of the long strip is provided with an inclined block with a slope. The inclined block is fixedly connected to one end of the buffer. The buffer can reduce the vibration of the cleaning component on the connecting frame, making the device operate more stably, and can also prevent the cleaning component from being stuck by large rocks, thereby improving the service life of the cleaning component.

[0013] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0014] (1) By setting an adjustment frame and a rotatable mounting frame, the tilt angle of the plow blade can be changed to avoid obstacles, and the distance between the plow blade and the vehicle body can be adjusted to make changes according to the conditions of the cultivated land, thereby improving the flexibility of the device.

[0015] (2) By setting up a cleaning component, this utility model can remove stones buried in the soil, prevent stones from damaging the plow blade, and improve the service life of the plow blade, thereby improving the plowing effect. By setting up a buffer, it can buffer the connecting component, making the vehicle body run more stably, and can prevent large stones from jamming the cleaning component, effectively improving the service life and practicality of the device.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1:

[0024] refer to Figure 1 and Figure 2An adjustable plowing device includes a vehicle body 1, a connecting frame 2 on one side of the vehicle body 1, a crossbeam 22 on one side of the connecting frame 2, and multiple adjusting frames 3 on one side of the crossbeam 22. A drive block 4 is slidably mounted inside each of the multiple adjusting frames 3. A connecting rod 5 is rotatably mounted on both sides of the drive block 4. A mounting frame 6, which can tilt left and right, is mounted at one end of the connecting rod 5. A plowing rod 7 is rotatably mounted on the end face of the mounting frame 6. A plow blade 8 is mounted at the bottom of the plowing rod 7. The plowing rod 7 is rotatably connected to the mounting frame 6. A cleaning component 9 is rotatably mounted at the bottom of the connecting frame 2, and a buffer 10 is rotatably mounted on one side of the cleaning component 9.

[0025] In this design, the cleaning component 9 is a flat, hook-shaped part, which facilitates breaking the soil. The cleaning component 9 can detect and clear the soil to be cultivated in front, and move the stones buried in the soil, making it easier for the subsequent plow blade 8 to plow the land, thereby improving the plowing effect of the plow blade 8. When the tip of the cleaning component 9 contacts the large stone, the cleaning component 9 will rotate due to the continued pulling of the vehicle body 1, squeezing the buffer 10, and thus passing over the surface of the stone to prevent jamming and ensure normal operation.

[0026] refer to Figure 2 and Figure 3 The adjusting frame 3 has a threaded rod 11 inside for rotation, and a moving block 12 is provided on the surface of the threaded rod 11. The moving block 12 is fixedly connected to the driving block 4.

[0027] In this scheme, when the threaded rod 11 is rotated, the threaded rod 11 will drive the moving block 12 to move to one side. The moving block 12 will drive the driving block 4 at the bottom to move. The driving block 4 can drive one end of the connecting rods 5 on both sides to move, thereby changing the distance between the mounting frame 6 and the crossbeam 22, causing the mounting frame 6 to tilt, thus achieving the purpose of angle adjustment.

[0028] refer to Figure 2 and Figure 4 Short rods 13 are rotatably mounted at both ends of the crossbeam 22. The short rods 13 are rotatably connected between the two connecting rods 5. A connector 17 is rotatably mounted on the top of the connecting frame 2. A fixing rod 18 is rotatably mounted on one end of the connector 17. The other end of the fixing rod 18 is rotatably connected to the plow rod 7. The bottom of the connector 17 is rotatably connected to the connecting frame 2. By setting the connector 17, the fixing rod 18 can be adaptively rotated and its angle changed when the plow rod 7 changes its angle and distance.

[0029] In this design, by setting a short rod 13, when the angle of the connecting rod 5 changes, the connecting rod 5 can rotate around the connection point of the short rod 13, which provides support for the connecting rod 5 and ensures the stable operation of the device.

[0030] refer to Figure 2 and Figure 3The bottom of the threaded rod 11 is provided with a slide rail 14 on the end face of the adjusting frame 3. A limit slider 15 is slidably provided on the surface of the slide rail 14. The limit slider 15 is fixedly connected to the drive block 4. A handle 16 is provided on one side of the threaded rod 11 on the surface of the adjusting frame 3.

[0031] In this case, the limiting slider 15 can restrict the movement direction of the drive block 4 and provide a certain support for the connecting rod 5, reducing the pressure on the threaded rod 11 and thus improving the service life of the threaded rod 11.

[0032] refer to Figure 4 and Figure 5 The bottom of the connecting frame 2 is provided with a locking block 19, the bottom of the locking block 19 is provided with a detachable strip 20, the bottom of the strip 20 is provided with a beveled block 21 with an inclined surface, and the beveled block 21 is fixedly connected to one end of the buffer 10.

[0033] In this solution, the buffer 10 can reduce the vibration of the cleaning component 9 to the connecting frame 2, making the device operate more stably, and also prevent the cleaning component 9 from being stuck by large stones, thus improving the service life of the cleaning component 9. The buffer 10 is existing technology, and its main function is to buffer the vibration brought by the cleaning component 9 during cultivation. The detachable strip 20 facilitates the replacement and maintenance of the cleaning component 9.

[0034] When changing the angle, the operator needs to rotate the handle 16 on one side of the adjustment frame 3. Rotating the handle 16 will drive the threaded rod 11 to rotate, which will drive the moving block 12 on the surface to move to one side. The moving block 12 will drive the driving block 4 at the bottom to move, and the driving block 4 can drive one end of the connecting rods 5 on both sides to move. Since the short rod 13 on one side is supported, the connecting rod 5 rotates around one end of the short rod 13, thereby shortening the distance between one side of the mounting frame 6 and the crossbeam 22, causing the mounting frame 6 to tilt, thus achieving the purpose of angle adjustment. At the same time, rotating both handles 16 can change the angle of the connecting rods 5 on both sides simultaneously, shortening the parallel distance between the mounting frame 6 and the crossbeam 22. The specific adjustment can be made according to the actual situation to improve the flexibility of the equipment.

[0035] When the vehicle body 1 is working, the cleaning component 9 at the bottom of the connecting frame 2 can detect and clean the soil to be tilled in front of the plow blade 8, and move the stones buried in the soil, so that the subsequent plow blade 8 can plow the land more easily, thereby improving the plowing effect of the plow blade 8. When the tip of the cleaning component 9 contacts the large stone, the cleaning component 9 will rotate due to the continued pulling of the vehicle body 1, squeezing the buffer 10, so that it can pass over the surface of the stone to prevent jamming and ensure normal operation.
