[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-7 As shown, the present invention is a curb stone removal device for the renovation of municipal green belts, including a transport vehicle 1, a mounting frame 2 fixedly connected to the side surface of the transport vehicle 1, a connecting frame 9 fixedly installed on one end surface of the mounting frame 2, a connecting arm 28 rotatably connected to the inner side of the mounting frame 2 near one end edge, and a pad 34 provided on the inner side of the mounting frame 2 near the other end edge.

[0028] A connecting shaft 11 is rotatably connected to the side surface of the connecting frame 9. A first cylinder 12 is sleeved and connected to the surface of the connecting shaft 11. A connecting rod 13 is sleeved and connected to the output end of the first cylinder 12. A movable arm 14 is rotatably connected to the inner side of the connecting frame 9 near a short side. A sleeve 15 is welded and fixed to the inner side of the movable arm 14. Connecting cylinders 16 are symmetrically welded and fixed to the inner side of the movable arm 14 near one short side. The connecting cylinders 16 are sleeved and connected to the connecting rod 13. A cutting blade 20 is provided on the inner side of the movable arm 14 near the bottom end. An insert rod is embedded and connected to the inner side of the connecting frame 9 near a short side. 15 is engaged with the insert rod. When removing curb stones, the cement at the joint of the connected curb stones must first be cut off so that the removal equipment can remove the curb stones one by one. When cutting, the transport vehicle 1 is driven until the cutting blade 20 stops at the joint of two adjacent curb stones. Then the first cylinder 13 is started so that its output end slowly extends. During the process, the movable arm 14 will rotate around the insert rod under the action of the sleeve 15, thereby driving the cutting blade 20 to continuously approach the joint of the curb stones. Then the cutting blade 20 can be started to begin the cutting operation.

[0029] A first mounting plate 3 is fixedly installed on one end surface of the mounting frame 2. A second mounting plate 4 is fixedly installed on the inner side of the mounting frame 2 near one end edge. A bearing plate 5 is fixedly installed on the bottom surface of the mounting frame 2. A transverse rail 6 is symmetrically fixedly installed on the top surface of the inner side of the mounting frame 2. A hanging seat is movably connected to the surface of the transverse rail 6. A longitudinal rail 7 is fixedly installed on the surface of the hanging seat. A hanger 8 is movably connected to the surface of the longitudinal rail 7. A lifting cylinder is fixedly installed on the surface of the hanger 8. A hanging seat is fixedly installed at the output end of the lifting cylinder. This mounting frame 2 assembly is transported by the transport vehicle 1. When removing the curbstone, after the curbstone is clamped and fixed by the pad plate 34 assembly, the lifting cylinder can be activated, causing the hanging seat to lift the pad plate 34 assembly. Then, with the cooperation of the transverse rail 6 and the longitudinal rail 7, the curbstone is piled up in a certain position, and then the next curbstone can be removed and transported.

[0030] A fixed arm 10 is fixedly connected to the bottom surface of the inner side of the connecting frame 9. A dust baffle is welded and fixed to the surface of the fixed arm 10. A baffle 17 is welded and fixed to the inner side of the movable arm 14. A motor 18 is fixedly installed on the surface of the baffle 17.

When performing cutting operations, the motor 18 needs to be started to control the cutting blade 20 to rotate. The retaining sleeve 19 can prevent the dust and impurities from flying everywhere. Together with the dust baffle and the baffle 17, the range of dust and impurities can be further limited, thereby reducing the cleaning workload of workers.

[0031] A baffle 22 is fixedly installed on the bottom surface of the top box 21. A mounting frame 23 is fixedly installed on the inner side of the top box 21. A dust collector bag 24 is fitted and connected to the surface of the mounting frame 23. A fan 25 is fixedly installed on one short side surface of the top box 21. A pulse tube 26 is fixedly installed on one short side surface of the top box 21 on one side of the fan 25. The pulse tube 26 is fixedly connected to an external air pump. A cover 27 is fixedly connected to the top surface of the top box 21. During the cutting operation, when dust and impurities fly and splash between the dust baffle and the baffle 17, larger dust and impurities will fall off after touching the baffle 22, while smaller dust and impurities will adhere to the surface of the dust collector bag 24 under the negative pressure of the fan 25. After the curb stone removal process has been carried out for a period of time, the external air pump can be started to blow off the attached dust and impurities, so that the dust and impurities during the surface operation are controlled to fly away.

[0032] A geared motor is fixed to one end of the second mounting plate 4. A linkage shaft is fixedly mounted on the surface of the geared motor. A linkage frame 29 is fixedly connected to the facing surfaces of the two connecting arms 28. The linkage shaft is fixedly connected to the linkage frame 29. A second cylinder 30 is rotatably connected to the inner side of the connecting arm 28. An arc-shaped frame 31 is rotatably connected to one end of the side surface of the connecting arm 28. The output end of the second cylinder 30 is engaged with the arc-shaped frame 31. A connecting frame 32 is rotatably connected to the side surface of the arc-shaped frame 31. One end of the connecting arm 28 is rotatably connected to... With bucket 33, after the connecting section of the curbstone is cut off, part of its bottom is still buried in the soil. In order to reduce the subsequent demolition workload and speed up the demolition efficiency, the curbstone needs to be scooped from the side to facilitate its easy clamping and transportation. In specific operation, first make the bucket 33 vertically downward. After extending it to the lower part of the curbstone, the second cylinder 30 can be slowly started, so that the bucket 33 begins to rotate with the cooperation of the arc frame 31 and the connecting frame 32 until the bottom of the curbstone is scooped up and shaken.

[0033] A top plate is fixedly connected to the top surface of the pad 34. A dustproof plate 35 is welded and fixed to the bottom surface of the top plate near one short side. A drive box 36 is welded and fixed to the bottom surface of the top plate near another short side. A hanging column 37 is fixedly installed on the top surface of the top plate. A through groove is symmetrically fixedly connected to one end surface of the pad 34.

[0034] A gear frame 38 is symmetrically rotatably connected to one end surface of the pad 34. A docking frame 39 is welded and fixed to the side surface of the gear frame 38. A slant frame 40 is rotatably connected to the surface of the docking frame 39 near one end edge. A clamping frame 41 is fixedly connected to the bottom surface of the slant frame 40. A sleeve frame 42 is rotatably connected to the two short side surfaces of the slant frame 40 near the bottom end. A sleeve shaft 43 is fixedly connected to the surface of the sleeve frame 42. The sleeve shaft 43 engages with the through groove. Before moving the curb stone, it needs to be clamped and fixed. During operation, the drive box 3 needs to be started. 6. Using its internal motor, one set of gear frames 38 is driven to rotate. At the same time, the other set of gear frames 38 will also rotate in opposite directions during the meshing process. During the process of the two sets of docking frames 39 flipping downwards at the same time, the inclined frame 40 connected to it is also affected by the support of the sleeve frame 42. The clamping frame 41 at its bottom always remains vertical during the movement process until the clamping frame 41 is against the surface of the curbstone, thereby completing the clamping and fixing of the curbstone. The drive motor rotates in the opposite direction to complete the placement of the curbstone.

[0035] The working principle of this invention is as follows: When removing curb stones, the cement at the joints of the adjacent curb stones must first be cut away to allow the removal equipment to remove the curb stones one by one. During the cutting operation, the transport vehicle 1 is first driven until the cutting blade 20 stops at the joint of two adjacent curb stones. Then, the first cylinder 13 is activated, causing its output end to slowly extend. During this process, the movable arm 14 rotates around the insert rod under the action of the sleeve 15, thereby driving the cutting blade 20 to continuously approach the curb stone joint. Then, the cutting blade 20 can be activated to begin the cutting operation. During the cutting operation, the motor 18 needs to be started to control the rotation of the cutting blade 20. The setting of the retaining sleeve 19 allows... To prevent dust and impurities from flying everywhere during cutting, the dust baffle and baffle 17 further limit the range of dust and impurities, thereby reducing the workload of workers. During the cutting operation, when dust and impurities fly and splash between the dust baffle and baffle 17, larger dust and impurities will fall off after hitting the baffle mesh 22, while smaller dust and impurities will adhere to the surface of the dust collection bag 24 under the negative pressure suction of the fan 25. After the curb stone removal process has been going on for a while, the external air pump can be started to blow off the adhered dust and impurities. Thus, the dust and impurities during the surface operation are controlled to fly away. After the curb stone connecting section is cut off, part of its bottom is still buried in the soil. To reduce subsequent demolition work and accelerate demolition efficiency, the curbstone needs to be scooped from the side to facilitate easy clamping and handling. Specifically, the bucket 33 is first positioned vertically downwards. After extending towards the lower end of the curbstone, the second cylinder 30 is slowly activated, causing the bucket 33 to rotate with the cooperation of the arc frame 31 and connecting frame 32 until the bottom of the curbstone is lifted and shaken. Before handling the curbstone, it needs to be clamped and secured. During operation, the drive box 36 is activated, using its internal motor to rotate one set of gear frames 38. Simultaneously, the other set of gear frames 38 will rotate in opposite directions during the meshing process. Both sets of connecting frames 39 move simultaneously towards... During the downward flipping process, the inclined frame 40 connected to it is also affected by the support of the sleeve frame 42. The clamping frame 41 at its bottom always remains vertical during the movement until the clamping frame 41 is against the surface of the curbstone, thereby completing the clamping and fixing of the curbstone. The drive motor rotates in the opposite direction to complete the placement of the curbstone. This mounting frame 2 assembly is transported by the transport vehicle 1. When the curbstone is removed, after the curbstone is clamped and fixed by the pad plate 34 assembly, the lifting cylinder can be activated to make the lifting seat drive the pad plate 34 assembly to rise. Then, with the cooperation of the transverse rail 6 and the longitudinal rail 7, the curbstone is piled up in a certain position, and then the next curbstone can be removed and transported.

[0036] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
