[0002] Municipal garden roads refer to roads in cities that incorporate landscaping elements. These roads not only have basic transportation functions, but also enhance the city's ecological environment and the quality of life for residents through greening and beautification.

[0003] Curbstones are often laid along the sides of municipal and garden roads. When the road has a certain curvature, the curbstones need to be cut at the corners. Currently, most workers cut the corners of the curbstones manually using a handheld cutting machine. This method is not only difficult to control the cutting angle, but the dust generated can also harm the health of the workers. Therefore, we urgently need a curbstone corner cutting device for municipal and garden roads. Utility Model Content

[0016] Beneficial effects

[0017] This utility model provides a corner-cutting device for curb stones in municipal garden roads, which has the following beneficial effects:

[0018] 1. By setting a curbstone limiting plate and locking mechanism, along with angle scale lines, the curbstone can be placed and limited at a certain angle. Then, the cutting mechanism and the curbstone pressing mechanism are moved down by the telescopic push rod, so that the curbstone can be fixed and cut. Compared with handheld cutting machines, not only can the cutting angle be controlled, but the operation process is also safer.

[0019] 2. By incorporating a water tank, horizontal water pipe, atomizing nozzle, water supply pipe, and telescopic airbag, when the telescopic push rod extends and drives the cutting mechanism to cut the curbstone, the movable rod and sleeve will move relative to each other.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figure 1-4This utility model provides a curbstone cutting device for municipal garden roads, including a transport cart 1. A gantry frame 2 is fixedly connected to the surface of the transport cart 1. Angle scale lines 3 are provided on the surface of the transport cart 1. A telescopic push rod 4 is fixedly connected to the lower surface of the gantry frame 2. The telescopic push rod 4 can be any of an electric push rod, hydraulic cylinder, or pneumatic cylinder. A cutting mechanism 5 is fixedly connected to the movable end of the telescopic push rod 4. The cutting mechanism 5 includes a cutting tool and a drive motor for driving the cutting tool. In this embodiment, the drive motor is a servo motor to facilitate precise control of speed and torque. The saw disc is a diamond saw disc suitable for stone cutting, and the diamond saw disc is fixedly connected to the output end of the servo motor. The upper end surface of the transport cart 1 is respectively provided with a lower cutting groove 6 and an arc-shaped through groove 7, and the lower cutting groove 6 corresponds to the cutting mechanism 5. A curbstone limiting plate 8 is also placed on the upper end surface of the transport cart 1. The curbstone limiting plate 8 is as follows: Figure 1 and Figure 2 As shown, a receiving groove for placing curb stones is provided on one side. A locking mechanism 9 for fixing the curb stone limiting plate 8 is provided in the arc-shaped through groove 7. The movable end of the telescopic push rod 4 is connected to the adjusting plate 10 with damping rotation. The movable end of the telescopic push rod 4 is provided with a friction damper. The adjusting plate 10 and the movable end of the telescopic push rod 4 are connected with damping rotation through the friction damper. The surface of the adjusting plate 10 is provided with a curb stone pressing mechanism 11. By setting the curb stone limiting plate 8 and the locking mechanism 9, and with the help of the angle scale line 3, the curb stone can be placed and limited at a certain angle. Then, the telescopic push rod 4 drives the cutting mechanism 5 and the curb stone pressing mechanism 11 to move down, thereby fixing and cutting the curb stone. Compared with cutting with a handheld cutting machine, not only can the cutting angle be controlled, but the operation process is also safer.

[0028] A protective cover 12 is provided on the outside of the cutting mechanism 5 and is fixedly connected to the gantry frame 2. By providing the protective cover 12, the operator can be effectively prevented from accidentally touching the cutting mechanism 5, thereby improving the safety of the device during operation.

[0029] The locking mechanism 9 includes a bottom baffle 13, a threaded post 14, and a wing nut 15. The bottom baffle 13 is fixedly connected to the lower end of the threaded post 14. The threaded post 14 passes through the arc-shaped through groove 7 and is threadedly connected to the curbstone limiting plate 8. The wing nut 15 is threadedly connected to the outside of the threaded post 14. By setting the locking mechanism 9 and tightening the wing nut 15, the bottom baffle 13 and the wing nut 15 can press against each other from above and below to fix the curbstone limiting plate 8.

[0030] The bottom baffle 13 has several anti-slip strips 16 arranged in a ring array on its surface. By setting the anti-slip strips 16, the friction between the bottom baffle 13 and the lower surface of the transport cart 1 can be increased, thereby improving the fixing effect of the curbstone limiting plate 8.

[0031] The curbstone pressing mechanism 11 includes a pressing plate 17, a sleeve 18, a movable rod 19, a baffle plate 20, and a spring 21. The sleeve 18 is fixedly connected to the surface of the steering plate 10. The upper end of the movable rod 19 is slidably connected to the inner wall of the sleeve 18. The pressing plate 17 is fixedly connected to the lower end of the movable rod 19. The baffle plate 20 is fixedly connected to the inner wall of the sleeve 18. The spring 21 is fixedly connected between the movable rod 19 and the baffle plate 20. When the telescopic push rod 4 moves the curbstone pressing mechanism 11 downward, the pressing plate 17 will move downward along with it. The spring 21 applies elastic force to the movable rod 19, which can make the pressing plate 17 press down on the curbstone. With the help of the curbstone limiting plate 8, the curbstone can be fixed.

[0032] Example 2

[0033] Please see Figure 1-4 Including Embodiment 1, and based on Embodiment 1, this utility model provides a technical solution: a water tank 22 is fixedly connected to the top of the gantry frame 2, and a horizontal water pipe 23 is fixedly connected to the inner side of the protective cover 12. The horizontal water pipe 23 is located directly above the cutting mechanism 5, and multiple atomizing nozzles 24 are equidistantly arranged on its lower surface. A water supply pipe 25 is connected between the lower end of the water tank 22 and the horizontal water pipe 23. The water tank 22 is a sealed cavity, and a water filling pipe 26 is connected to its upper end. A pipe plug is provided at the inlet of the water filling pipe 26. By setting the water filling pipe 26 and the pipe plug, water can be conveniently added to the water tank 22.

[0034] A telescopic airbag 27 is fixedly connected between the baffle plate 20 and the movable rod 19. An air inlet pipe 28 and an exhaust pipe 29 are respectively provided on the upper end of the sleeve 18, with the upper end of the exhaust pipe 29 extending to the upper part of the water tank 22. More preferably, it can be positioned above the water surface in the water tank 22. The lower ends of both the air inlet pipe 28 and the exhaust pipe 29 are interconnected with the telescopic airbag 27, and both the air inlet pipe 28 and the exhaust pipe 29 are equipped with one-way valves. This is achieved by configuring the water tank 22, the horizontal water pipe 23, the atomizing nozzle 24, and the water delivery pipe. 25. Telescopic airbag 27, etc. When the telescopic push rod 4 extends and drives the cutting mechanism 5 to cut the curbstone, the movable rod 19 and the sleeve 18 will move relative to each other. By using the movable rod 19 to squeeze the telescopic airbag 27, the air in the telescopic airbag 27 can be discharged from the exhaust pipe 29 into the water tank 22. By increasing the air pressure in the water tank 22, the water in the water tank 22 can be sprayed from the water supply pipe 25 through the horizontal water pipe 23 and finally from the atomizing nozzle 24, thereby reducing the dust generated during the cutting process.

[0035] After the gas inside the telescopic airbag 27 is expelled, it needs to be replenished. Therefore, by retracting the telescopic push rod 4, the sleeve 18 will move upward. After the lower pressure plate 17 is no longer in contact with the curbstone, the movable rod 19 will extend under the elastic force of the spring 21. At this time, the telescopic airbag 27 will expand and reset, so that outside air can be drawn into the telescopic airbag 27 through the air intake pipe 28.

[0036] It should be noted that in this embodiment, the exhaust pipe 29 is a flexible hose, which allows it to adapt to the up-and-down movement of the sleeve 18. Moreover, both the air inlet pipe 28 and the exhaust pipe 29 are equipped with one-way valves to ensure the uniqueness of the airflow direction. The air inlet pipe 28 can only perform the function of air intake, and the exhaust pipe 29 can only perform the function of air exhaust, thus preventing air from being drawn into the water tank 22 when the telescopic push rod 4 moves down. In addition, to ensure an effective atomization effect, the effective compression volume of the telescopic airbag 27 is matched with the reserved air volume at the top of the water tank 22. During one pressing stroke, the air discharged by the telescopic airbag 27 is sufficient to significantly increase the air pressure in the water tank 22 from the unpressurized state to the preset working pressure (e.g., an increase of 0.5-1.0 bar). This pressure is sufficient to drive the water flow through the water supply pipe 25 and the horizontal water pipe 23, and spray it out from multiple atomizing nozzles 24 to form a water mist that can effectively suppress dust.

[0037] The working principle of this device is as follows:

[0038] Preparation stage: According to the cutting angle requirements, loosen the wing nut 15 of the locking mechanism 9, move the curbstone limiting plate along the arc groove 7, align it with the angle scale line 3, tighten the wing nut 15 to lock it, place the curbstone to be cut on the transport trolley 1, so that one end of the curbstone is placed in the receiving groove of the curbstone limiting plate 8.

[0039] Cutting and dust removal stage: Start the servo motor of the cutting mechanism 5, and then start the telescopic push rod 4 to extend and descend;

[0040] a. Pressing down: As the telescopic push rod 4 moves downward, the pressing plate 17 of the curbstone pressing mechanism 11 first contacts and presses down on the curbstone;

[0041] b. Pressurization and spraying: During the pressing process, the movable rod 19 moves upward relative to the sleeve 18, thereby compressing the telescopic airbag 27 between the two. Under pressure, the air in the airbag is forced into the sealed space at the top of the water tank 22 through the one-way valve on the exhaust pipe 29, causing the air pressure in the water tank to rise. The increased air pressure forces the water in the water tank through the water supply pipe 25 and the horizontal water pipe 23, and finally sprays it out from the atomizing nozzle 24 in the form of water mist to pre-wet and reduce dust in the area to be cut.

[0042] c. Cutting: The servo motor drives the diamond saw disc of the cutting mechanism 5 to cut the firmly pressed and positioned curbstone along a predetermined path. The entire cutting process is accompanied by continuous dust suppression spray.

[0043] Reset phase: After the cutting is completed, the telescopic push rod 4 retracts and moves upward, the lower pressure plate 17 disengages from the curbstone, and under the action of the spring 21, the movable rod 19 resets, causing the compressed telescopic airbag 27 to expand. At this time, outside air is drawn into the airbag through the one-way valve on the air intake pipe 28, preparing for the next pressurization.

[0044] Compared to handheld cutting machines, this device not only allows for control of the cutting angle but also ensures safer operation. When the lower pressure plate 17 presses down to fix the curbstone, the movable rod 19 compresses the telescopic airbag 27, allowing air inside the airbag 27 to be discharged into the water tank 22 through the exhaust pipe 29. By increasing the air pressure inside the water tank 22, water inside the tank is sprayed from the water supply pipe 25 through the horizontal water pipe 23 and finally out of the atomizing nozzle 24. This effectively reduces dust generated during the cutting process, which is beneficial to the health of workers. Furthermore, the atomizing nozzle 24 does not require electricity to operate, making the entire device more energy-efficient and environmentally friendly.

[0045] The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0046] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
