[0025] Depend on Figures 1-6 As shown, a curbstone laying machine includes a frame 1. Two grooves are formed on the outer wall of the frame 1. Mounting plates 2 are slidably connected to the inner walls of the two grooves. Two sixth hydraulic cylinders are fixedly connected inside the grooves. The top of the output end of the two sixth hydraulic cylinders is fixedly connected to the bottom of the two mounting plates 2 respectively. The same end plate 3 is fixedly connected to one end of the two mounting plates 2. Forks 4 are fixedly connected to the outer wall of the end plate 3. The forks 4 are lifted by the operation of the sixth hydraulic cylinders. Since the curbstones are generally heavy, pads are placed at the bottom when they are lifted and placed by a crane.

[0026] The top of the frame 1 has a circular groove, and a gear 5 is rotatably connected to the inner wall of the groove. A first motor is fixedly connected inside the groove, and a spur gear 6 is fixedly connected to the top of the output end of the first motor. The spur gear 6 and the gear 5 are meshed. When the first motor runs, the spur gear 6 rotates, and the rotation of the spur gear 6 causes the gear 5 to rotate. A boss 7 is fixedly connected to the top of the gear 5, and the rotation of the gear 5 causes the boss 7 to rotate.

[0027] The top of the boss 7 is fixedly connected to a first hydraulic cylinder 8, and the top of the boss 7 is fixedly connected to two support columns 10. The top of the output end of the first hydraulic cylinder 8 is fixedly connected to a frame 9. The outer wall of the frame 9 has two sliding holes, and the inner walls of the two sliding holes are slidably connected to the outer walls of the two support columns 10 respectively. The two support columns 10 assist the frame 9 in lifting and lowering.

[0028] The top of the frame 9 has a long slot, and the inner wall of the long slot is fixedly connected to a second hydraulic cylinder 11. The outer wall of the output end of the second hydraulic cylinder 11 is fixedly connected to a first T-block 12. The bottom of the frame 9 has an assembly slot, and the inner wall of the assembly slot is slidably connected to the outer wall of the first T-block 12. The bottom of the first T-block 12 is fixedly connected to a mounting frame 13. The operation of the second hydraulic cylinder 11 causes the first T-block 12 to drive the mounting frame 13 to move back and forth. The outer wall of the frame 9 is fixedly connected to two round rods 14. The outer wall of the mounting frame 13 has two round holes, and the inner walls of the two round holes are slidably connected to the outer walls of the two round rods 14 respectively. The mounting frame 13 moves back and forth through the two round rods 14, increasing the stability of the mounting frame 13 when it moves.

[0029] The bottom of the mounting bracket 13 has two T-slots. The inner walls of the two T-slots are slidably connected to second T-blocks 15. The bottom of the second T-blocks 15 is rotatably connected to ball bearings to reduce friction. The bottom of the two second T-blocks 15 is fixedly connected to vertical plates 16. The second T-blocks 15 assist the vertical plates 16 in moving and increase stability. The outer walls of the two vertical plates 16 are rotatably connected to pressing plates 17, which mainly clamp and fix the curbstone.

[0030] Two third hydraulic cylinders 18 are fixedly connected to the bottom of the mounting frame 13. The outer walls of the output ends of the two third hydraulic cylinders 18 are fixedly connected to the outer walls of the two vertical plates 16 respectively. The two third hydraulic cylinders 18 rotate relative to each other, causing the two vertical plates 16 to rotate relative to each other. The mounting frame 13 is equipped with a support mechanism, and a placement frame 23 is fixedly connected to the outer wall of the frame 1.

[0031] A cavity is provided on the right outer wall of the frame 1. A fourth hydraulic cylinder 24 is fixedly connected to the inner wall of the cavity. A through hole is provided on the outer wall of the placement frame 23. The inner wall of the through hole is slidably connected to the outer wall of the output end of the fourth hydraulic cylinder 24. An L-shaped support plate 25 is fixedly connected to the outer wall of the output end of the fourth hydraulic cylinder 24. The operation of the fourth hydraulic cylinder 24 causes the L-shaped support plate 25 to move left and right, conveying the curbstone to one side of the inner wall of the placement frame 23, so that it is located below the two L-shaped clamps 29. The placement frame 23 is equipped with a placement mechanism. A U-shaped hook 30 is provided on the outer wall of the frame 1.

[0032] The supporting mechanism includes a second motor 21. A rectangular groove is provided on the outer wall of the mounting frame 13. Two rotating rods 19 are rotatably connected to the inner wall of the rectangular groove. Transmission gears 20 are fixedly sleeved on the outer walls of the two rotating rods 19. The two transmission gears 20 are meshed with each other. The inner wall of the rectangular groove is fixedly connected to the outer wall of the second motor 21. One end of the output shaft of the second motor 21 is fixedly connected to one end of one of the rotating rods 19. L-shaped rods 22 are fixedly connected to the outer walls of the two rotating rods 19. Two sliding grooves are provided at the bottom of the mounting frame 13. The inner walls of the two sliding grooves are slidably connected to the outer walls of the two L-shaped rods 22 respectively. When the second motor 21 is running, the two rotating rods 19 rotate relative to each other through the meshing of the two transmission gears 20, thereby causing the two L-shaped rods 22 to rotate relative to each other.

[0033] The placement mechanism includes a fifth hydraulic cylinder 26. A fixing plate is fixedly connected to the outer right side of the placement frame 23. The top of the fixing plate is fixedly connected to the bottom of the fifth hydraulic cylinder 26. An I-shaped plate 27 is fixedly connected to the top of the output end of the fifth hydraulic cylinder 26. Two electric push rods 28 are fixedly connected to the top of the I-shaped plate 27. The operation of the fifth hydraulic cylinder 26 causes the I-shaped plate 27 and the two electric push rods 28 to move up and down. An L-shaped clamping plate 29 is fixedly connected to the outer wall of the output end of the two electric push rods 28. Multiple rollers are rotatably connected to the inner wall of the placement frame 23. The multiple rollers are located below the L-shaped clamping plate 29.

[0034] Working principle: In use, the frame 1 is connected to the existing electric tractor and U-shaped hook 30, driving the frame 1 to move. The sixth hydraulic cylinder operates to lift the stacked curb stones with the forks 4. The electric tractor then moves the curb stones to a predetermined position. The first hydraulic cylinder 8 operates to move the frame 9 downward, positioning the two pressing plates 17 on the mounting bracket 13 above the curb stones on both sides. The second hydraulic cylinder 11 operates to move the first T-block 12 back and forth, adjusting the position of the mounting bracket 13 and aligning the two pressing plates 17 with the sides of the curb stones. The second motor 21... The operation causes one of the rotating rods 19 to rotate, while the other rotating rod 19 rotates relative to the other via two transmission gears 20. This relative rotation of the two rotating rods 19 causes the two L-shaped rods 22 to rotate relative to each other, with the L-shaped rods 22 rotating outwards to facilitate the subsequent clamping of the curbstone by the extrusion plate 17. After resetting, the bottoms of the two L-shaped rods 22 are located at the bottom of the curbstone, supporting it and preventing slippage. The operation of the first hydraulic cylinder 8 causes the extrusion plate 17 to move downwards a certain distance, and the operation of the third hydraulic cylinder 18 causes the two vertical plates 16 to move relative to each other. The two extrusion plates 17 clamp the curbstone. The first hydraulic cylinder 8 slowly lifts the frame 9 and mounting bracket 13, suspending the curbstone. The first motor rotates, causing the spur gear 6 to rotate, which in turn rotates the gear disc 5. The gear disc 5 rotates, causing the first hydraulic cylinder 8 and frame 9 to rotate, which in turn rotates the mounting bracket 13 and the curbstone, positioning the curbstone above the placement frame 23. The first hydraulic cylinder 8 then moves the frame 9 and mounting bracket 13 downwards, placing the curbstone on the L-shaped support plate 25. The two third hydraulic cylinders 18 then move outwards via the two vertical plates 16, releasing the extrusion plates 17. In addition to fixing the position of the curbstone, the operation of the fourth hydraulic cylinder 24 causes the L-shaped support plate 25 to deliver the curbstone to the underside of the two L-shaped clamping plates 29. The operation of the fifth hydraulic cylinder 26 causes the I-shaped plate 27 and the two electric push rods 28 to move downwards, so that the bottom of the L-shaped clamping plate 29 fits against the top of the curbstone. The operation of the two electric push rods 28 causes the two L-shaped clamping plates 29 to move to the right to clamp the curbstone, and the side of the curbstone is pressed against the outer wall of the roller. The operation of the fifth hydraulic cylinder 26 drives the I-shaped plate 27 to move downwards, placing the curbstone in the predetermined position for paving. This eliminates the need for manual handling and repositioning, improving efficiency.
