It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1

[0025] Please refer to Figures 1-5, the present utility model provides a technical solution: a segmenting device for rural road construction, including a vehicle body 1. A handle 14 is fixedly installed on the side of the vehicle body 1. The handle 14 is made of PP plastic, and this material is widely used due to its light weight, corrosion resistance and low cost. In addition to PP plastic, the handle 14 can also be made of ABS plastic or aluminum alloy, and these materials also have good durability and corrosion resistance, and can adapt to various environmental conditions. Moving wheels 2 are installed on the bottom surface of the vehicle body 1, and the number of the moving wheels 2 is four groups. The four groups of moving wheels 2 are evenly distributed at the four corners of the bottom surface of the moving wheels 2, providing stable support and flexible moving ability. The moving wheels 2 are made of polyurethane material, and this material is wear-resistant and will not damage the road surface. At the same time, wheels made of rubber or nylon materials can also be used to adapt to different usage environments. A cylinder 3 is fixedly installed on the top surface of the vehicle body 1, and an output rod 4 is installed at the output end of the cylinder 3. A connecting frame 5 is fixedly installed at the bottom end of the output rod 4. The cylinder 3 drives the output rod 4 to move downward through air pressure, and this driving method is both efficient and reliable. The connection between the output rod 4 and the connecting frame 5 can adopt a threaded connection or a pin connection method, and these connection methods are both convenient for installation and disassembly and ensure the structural stability. A motor 6 is fixedly installed on the side of the connecting frame 5, and a cutting knife 7 is installed at the output end of the motor 6. The motor 6 provides power and drives the cutting knife 7 to rotate to cut the road surface into segments. The connection between the motor 6 and the cutting knife 7 can adopt a coupling connection, and this connection method can effectively transmit torque and also has a certain ability to compensate for deviation, ensuring the accuracy of cutting. A bent frame 8 is fixedly installed on the top surface of the vehicle body 1, and a scale 9 is provided on the surface of the bent frame 8. By observing the scale 9 on the surface of the bent frame 8, the current cutting depth can be accurately known. This design is both convenient and practical, ensuring the consistency and accuracy of the cutting depth, which is crucial for maintaining the road cutting quality. The bent frame 8 can be made of stainless steel to ensure that the scale 9 can still be clearly readable after long-term use.

[0026] Please refer to Figures 1-5, a mounting frame 10 is fixedly installed on the top surface of the vehicle body 1. The mounting frame 10 is of an "L" - shaped structure. A threaded rod 11 is penetratively arranged on the top surface of the mounting frame 10. Threads are provided inside the mounting frame 10 and are meshed with the threaded rod 11. A stop block 12 is fixedly installed at the bottom end of the threaded rod 11. By turning the threaded rod 11, the position of the stop block 12 can be adjusted, thereby adjusting the maximum cutting depth. This design allows the staff to flexibly adjust the cutting depth according to different road conditions, increasing the adaptability and practicality of the equipment. The threaded meshing design between the threaded rod 11 and the mounting frame 10 ensures the smoothness and accuracy of the adjustment process. A top block 13 is fixedly installed on the top surface of the bent frame 8. The stop block 12 can also block the top block 13. At this time, the maximum cutting depth can be mechanically limited, thereby ensuring the segmentation quality. The provided baffle 17 can block the front and rear of the cutting blade 7, which can avoid the dust thrown during cutting from rising, and thus protect the physical health of the staff. After the baffle 17 is damaged, the staff only needs to pull the baffle 17 downward. The baffle 17 then drives the cylinder 16 to move, and the cylinder 16 then drives the rubber ring 19 to move until the rubber ring 19 disengages from the annular groove 18. At this time, the baffle 17 can be removed. When installing the baffle 17, only need to align the cylinder 16 on the baffle 17 with the circular groove 15 and insert it until the cylinder 16 drives the rubber ring 19 to snap into the annular groove 18. At this time, the baffle 17 can be limited. This quick loading and unloading design not only facilitates maintenance and replacement, but also increases the flexibility and efficiency of the operation. The assembly method of combining the cylinder 16 and the rubber ring 19 is both simple and reliable, ensuring the stability of the baffle 17 during operation and being easy for the operator to replace quickly.

[0027] Embodiment Two

[0028] Please refer to Figures 4-5 , the splash - proof mechanism includes a circular groove 15, and the circular groove 15 is opened on the bottom surface of the vehicle body 1. In this structure, the circular groove 15 can be formed on the bottom surface of the vehicle body 1 through casting or welding technology. Casting provides integral strength, while welding facilitates the later installation on the existing vehicle body 1. The inner wall of the circular groove 15 is provided with a cylinder 16, and a baffle 17 is fixedly installed at the bottom end of the cylinder 16. The connection between the cylinder 16 and the baffle 17 can be fixed by bolts or welded. Bolt fixation is convenient for disassembly and replacement, while welding enhances the structural stability. An annular groove 18 is opened on the inner wall of the circular groove 15, and a rubber ring 19 is fixedly installed on the surface of the cylinder 16. The annular groove 18 and the rubber ring 19 are of the same size. This configuration enables the baffle 17 to be accurately positioned during assembly, and the rubber ring 19 provides good sealing and buffering properties, reducing vibration and noise.

[0029] Working principle: The cylinder 3 can drive the output rod 4 to move downward. Subsequently, the output rod 4 drives the connecting frame 5 to move, and the connecting frame 5 then drives the cutting knife 7 to move downward. Then, the motor 6 drives the cutting knife 7 to rotate. At this time, the road surface can be cut and segmented by the cutting knife 7. When the cutting knife 7 moves downward, the set output rod 4 can synchronously drive the bending frame 8 to move downward. At this time, by observing the scale 9 on the surface of the bending frame 8, the current cutting depth can be accurately known. This can facilitate the staff to check the cutting depth. And because it is a pure mechanical method, the reliability is relatively high, and the data is not easy to make mistakes. At the same time, the set stop block 12 can block the top block 13. At this time, the maximum cutting depth can be limited mechanically, so as to ensure the segmentation quality. At the same time, the maximum cutting depth can also be adjusted. The staff only needs to turn the threaded rod 11. At this time, because there is a thread in the mounting frame 10, the threaded rod 11 moves in the mounting frame 10 at this time, and the threaded rod 11 then drives the stop block 12 to move. By controlling the position of the stop block 12, the maximum cutting depth can be adjusted. Through the way of driving the output rod 4 and the connecting frame 5, combined with the bending frame 8 indicated by the scale 9, the operator can intuitively and accurately control and know the cutting depth. This design is both convenient and practical, ensuring the consistency and accuracy of the cutting depth, which is crucial for maintaining the road cutting quality. And by mechanically limiting the maximum cutting depth, it prevents potential safety problems or road structure damage caused by over-deep cutting, protecting the safety of the operator and the road. The set baffle 17 can block the front and rear of the cutting knife 7, so as to avoid the dust thrown during cutting from rising, thereby protecting the physical health of the staff. At the same time, after the baffle 17 is damaged, the staff only needs to pull the baffle 17 downward. Subsequently, the baffle 17 drives the cylinder 16 to move, and the cylinder 16 then drives the rubber ring 19 to move until the rubber ring 19 disengages from the annular groove 18. At this time, the baffle 17 can be removed. When installing the baffle 17, only need to insert the cylinder 16 on the baffle 17 into the circular groove 15 until the cylinder 16 drives the rubber ring 19 to snap into the annular groove 18. At this time, the baffle 17 can be limited. By the baffle 17 blocking the front and rear of the cutting knife 7, the utility model effectively prevents the dust thrown during cutting from rising, reduces the harm of dust to the respiratory system of the staff, and improves the safety of the working environment. And by using the method of inserting the cylinder 16 and the rubber ring 19 into the annular groove 18 to fix the baffle 17, not only makes the installation and disassembly of the baffle 17 simple, but also increases the connection stability, ensuring the stability of the baffle 17 during work.
