[0002] Curbstones are boundary stones placed at the edge of the road surface, also known as curbs or curbstones. They are used to distinguish the roadway, sidewalk, green space, median strip, and other parts of the road. They can make the edge of the road surface neat, thereby guiding pedestrians and vehicles to move in the direction of paving, thereby ensuring traffic safety and facilitating drainage. Curbstones usually have edges on all four corners to facilitate quick laying on the road surface. After laying the curbstones, the construction party usually grinds or trims the edges of the curbstones to reduce injuries caused by pedestrians or vehicles colliding with the curbstones.

[0003] When using the existing curb chamfering cutting machine, the staff usually holds a small cutting machine to perform chamfering cutting.

When in use, each movable frame 11 slides in the corresponding slide groove 12 by rotating the two screws 14, thereby making the first clamping roller 24 and the second clamping roller 25 on the same side close to each other, thereby clamping both sides of the stone 1. When the first clamping roller 24 and the second clamping roller 25 tightly clamp the stone 1, the two screws 14 are fixed by the locking mechanism, thereby preventing the movable plate 21 from moving in the slide groove 12. At this time, the movable frame 11 is squeezed by stepping on the pressing assembly so that the cutting mechanism is tightly in contact with the side wall of the stone 1, thereby facilitating the cutting of the curb stone. There is no need to hold the cutting mechanism by hand, which increases the stability of the cutting and reduces the workload and difficulty of the staff.

[0026] Specifically, the cutting mechanism includes a fixed frame 23 fixedly arranged between the two movable plates 21, a driving motor 41 is fixedly arranged on the fixed frame 23, and a cutting knife 42 is fixedly arranged at the output end of the driving motor 41; the two movable plates 21 are fixedly connected through the fixed frame 23, and there is an inclination angle between the driving motor 41 and the two movable plates 21, so that the cutting knife 42 can cut the corners of the stone 1, and the cutting knife 42 is driven by the driving motor 41 to rotate to cut the stone 1.

[0027] Specifically, two gears 15 are rotatably provided on one side of the mobile frame 11 away from the fixed frame 23, and the two gears 15 are fixedly connected to the two screws 14 in a one-to-one correspondence, and a toothed belt 16 is provided between the two gears 15; the two screws 14 are rotatably connected to the side wall of the mobile frame 11, and the two screws 14 pass through the side wall of the mobile frame 11 and are fixedly connected to the corresponding gears 15, and the two gears 15 are engaged with the toothed belt 16. When the first clamping roller 24 and the second clamping roller 25 need to clamp the stone 1, one screw 14 is rotated to start, and the two screws 14 can rotate at the same time through the cooperation of the gear 15 and the toothed belt 16, so that it is convenient to control the movement of the two movable plates 21 at the same time, and the stone 1 can be clamped more conveniently.

[0028] Specifically, the locking mechanism includes locking pins 17 fixedly mounted on each gear 15. Each locking pin 17 has several locking holes 171 on its outer circumferential surface. Fixed blocks 18 are fixedly mounted on both sides of the moving frame 11. Each fixed block 18 is threaded with bolts 19. A handle 172 is fixedly mounted on one of the locking pins 17. The handle 172 can rotate one of the locking pins 17, thereby driving the corresponding gear 15 and screw 14 to rotate. This causes the two screws 14 to rotate simultaneously, so that the first clamping rollers 24 and the second clamping rollers 25 move closer to each other and clamp the stone 1 tightly. After the stone 1 is clamped, the bolts 19 are turned to insert into the corresponding locking holes 171, thereby fixing the locking pins 17 and the screws 14.

[0029] Specifically, the pressing component includes limiting rods 37 fixedly mounted on the top of the movable frame 11. A support plate 35 is mounted on the movable frame 11, and a pedal 36 is fixedly mounted on the support plate 35. Each limiting rod 37 is slidably connected to the support plate 35. A cooling component is mounted on the movable frame 11. Each limiting rod 37 is inclined on the movable frame 11, and there is an inclination angle between the pedal 36 and the support plate 35. This allows the user to easily step on the pedal 36 and push it forward with their foot, thereby moving the movable frame 11 forward to facilitate cutting the edge of the stone 1. After the first clamping roller 24 and the second clamping roller 25 clamp the stone 1, stepping on the pedal 36 causes the support plate 35 to slide downward along the limiting rods 37, which allows the support plate 35 to press the cooling component, thus cooling the cutting blade 42 and reducing dust.

[0030] Specifically, the mobile frame 11 has a placement cavity 33. The cooling component includes a water storage bladder 31 disposed within the placement cavity 33. Multiple spray heads 32 are fixedly disposed on the side wall of the placement cavity 33, and each spray head 32 is fixedly connected to the water storage bladder 31. A compression block 34 is slidably disposed on the side of the support plate 35 near the water storage bladder 31. The support plate 35 is limited by each limiting rod 37, so that when the foot pedal 36 is stepped on, all sides of the support plate 35 descend simultaneously. During use, the water storage bladder 31 is filled with water. Insert the support plate 35 onto each limiting rod 37 and lock the squeezing block 34 into the placement cavity 33. At this time, step on the pedal 36 and push the pedal 36 forward. The pedal 36 gives the support plate 35 a downward force and a forward force, thereby causing the support plate 35 to move downward. When the support plate 35 moves downward, it squeezes the water storage bladder 31 through the squeezing block 34. The water in the water storage bladder 31 is sprayed through the spray head 32 onto the contact position between the cutting blade 42 and the stone 1, thereby cooling the cutting blade 42.

[0031] Specifically, a plurality of first rollers 13 are rotatably provided on the side of the movable frame 11 away from the support plate 35, and a second roller 26 is rotatably provided on the side of each movable plate 21 away from the support plate 35; the movable frame 11 abuts against the top of the stone 1 through each first roller 13, and each movable plate 21 abuts against the stone 1 through the second roller 26. The first rollers 13 and the second rollers 26 make it easier for the movable frame 11 and the movable plate 21 to move on the stone 1, thereby facilitating the cutting of the stone 1 by the cutting knife 42.

[0032] Specifically, a handrail 2 is fixedly provided on the movable frame 11; the handrail 2 can maintain the stability of the staff and can also facilitate the movement of the movable frame 11.

At this time, turn the handle 172 to make the locking column 17 drive one of the gears 15 and the screw 14 to rotate, and the two screws 14 are rotated at the same time through the toothed belt 16, so that the mobile plate 21 slides in the slide groove 12, and then the first clamping roller 24 and the second clamping roller 25 are close to each other. When the first clamping roller 24 and the second clamping roller 25 clamp the stone 1, the support plate 35 is inserted into each limit rod 37, and the extrusion block 34 is stuck in the placement cavity 33, and the drive motor 41 is started, and the drive motor 41 drives the cutting knife 42 to rotate The edge of the stone 1 is cut by stepping on the pedal 36 and pushing the pedal 36 forward with the foot. The pedal 36 moves downward to drive the support plate 35 and the squeezing block 34 to move downward. When the squeezing block 34 moves downward, the water storage bag 31 is squeezed so that the liquid in the water storage bag 31 is sprayed on the cutting knife 42 and the stone 1 through the spray head 32, thereby cooling the cutting knife 42 and reducing dust. By pushing the pedal 36 with the foot and coordinating with the rotating first clamping roller 24, the second clamping roller 25, the first roller 13, and the second roller 26, the movable frame 11 and the movable plate 21 can be moved, so as to facilitate the cutting of the stone 1.
