The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] The embodiment of the present invention provides a road surface finishing device suitable for road construction, such as Figure 1-10 As shown, the pavement finishing device suitable for road construction includes: a support plate 1 and a U-shaped plate 2 fixedly mounted on one side of the support plate 1; a connecting plate 3 rotatably mounted on the U-shaped plate 2; a cutter 6 for cutting the pavement provided below the connecting plate 3; an angle adjustment mechanism provided on the output rods of the U-shaped plate 2 and the connecting plate 3 for driving the connecting plate 3 to rotate and adjust the cutting angle of the cutter 6; and a drainage pipe 18 provided on one side of the connecting plate 3 for reducing dust when the pavement is cut.

[0034] In this embodiment, when cutting the broken road surface, firstly, the support plate 39 is connected to the external driving device, and then the driving device drives the device to move, so that the device moves to the specified position, and then the servo motor 10 is started, so that the output shaft of the servo motor 10 drives the first sprocket 13 to rotate, so that the first sprocket 13 drives the first chain 14 and the rectangular seat 12 to rotate, so that the rectangular seat 12 drives the cutter 6 to rotate synchronously, and then the cutter 6 slides down to contact the road surface, and the road surface is cut. When cutting, the drain pipe 18 drains water, and dust reduction is performed on the dust generated during cutting. At the same time, when it is necessary to adjust the cutting direction, the angle adjustment mechanism is first started, so that the angle adjustment mechanism drives the connecting plate 3 to rotate, so that the connecting plate 3 drives the cutter 6 to rotate synchronously. The cutting angle of the cutter 6 is adjusted. When the angle of the cutter 6 is adjusted, the cutting line of the cutter 6 is arc-shaped, so that the cutting direction can be flexibly adjusted according to the shape and size of different road damage, thereby improving the adaptability and efficiency of the repair operation. Through the angle adjustment mechanism, the cutter 6 can flexibly adjust the cutting angle to adapt to road damage of different shapes and sizes, thereby improving the adaptability and flexibility of the road repair operation. The flexible adjustment of the cutting direction of the cutter 6 makes the repair operation more accurate and efficient, reduces unnecessary material waste and repetitive labor, and improves work efficiency. Through the setting of the drain pipe 18, the dust generated by the cutting operation is effectively reduced, the working environment is improved, the health of the construction workers is protected, and the pollution of the dust to the surrounding environment is also reduced.

[0035] In a further preferred embodiment of the present invention, a fixing plate 4 is provided below the connecting plate 3, a mounting frame 5 is installed at the bottom of the fixing plate 4, the mounting frame 5 is adapted to the cutter 6, a group of rectangular seats 12 are provided in the mounting frame 5, an output rod of any rectangular seat 12 is rotatably connected to the mounting frame 5, and a group of rectangular seats 12 are all slidably connected to the output rod of the cutter 6.

[0036] In this embodiment, the rectangular seat 12 and the output rod of the cutter 6 are slidably connected, so that the cutter 6 can be quickly replaced, and the operation is relatively convenient. At the same time, the installation, replacement and maintenance of the cutter 6 are more convenient and quick, reducing the maintenance cost and time.

[0037] In a further preferred embodiment of the present invention, preferably, the angle adjustment mechanism includes: a gear 7 fixedly mounted on the output rod of the connecting plate 3; a first electric telescopic rod 8 fixedly mounted on the top of the U-shaped plate 2; and a rack 9 mounted on the output rod of the first electric telescopic rod 8, wherein the rack 9 is meshed with the gear 7.

[0038] In this embodiment, when it is necessary to repair the road surface, the control system will send an instruction to the first electric telescopic rod 8 to make it extend and retract according to a predetermined stroke. As the first electric telescopic rod 8 is extended and retracted, the rack 9 will move in a straight line direction. Since the rack 9 is meshed with the gear 7, the movement of the rack 9 will drive the gear 7 to rotate, and the gear 7 is fixedly sleeved on the output rod of the connecting plate 3, so the rotation of the gear 7 will drive the connecting plate 3 (and the fixed plate 4, the mounting frame 5 and the cutter 6 thereunder) to rotate, thereby adjusting the cutting angle. The rack 9 is driven to move by the first electric telescopic rod 8, and then the gear 7 is driven to rotate, thereby realizing precise control of the rotation angle of the connecting plate 3 and the cutter 6, making the adjustment of the cutting angle more accurate and reliable. The entire angle adjustment process is automatically completed by the first electric telescopic rod 8 without manual intervention, thereby improving the automation and efficiency of the operation. The design of the gear 7 and the rack 9 makes the structure of the angle adjustment mechanism more compact and reasonable, reduces the occupied space, and makes the entire device more beautiful and tidy. Since the structure of the angle adjustment mechanism is relatively simple and clear, it is also more convenient and quick to maintain and overhaul.

[0039] In a further preferred embodiment of the present invention, a servo motor 10 and a mounting block 11 are fixedly installed on the top of the fixed plate 4, and a first sprocket 13 is fixedly sleeved on the output rod of the mounting block 11 and the rectangular seat 12, and a first chain 14 is sleeved on a group of the first sprockets 13, and the first chain 14 is meshed with a group of first sprockets 13 and passes through the fixed plate 4.

[0040] In this embodiment, when the road surface cutting operation is performed, the servo motor 10 starts and drives the output rod of the first sprocket 13 to rotate, and then transmits power to the first sprocket 13 on the rectangular seat 12 through the first chain 14. The rectangular seat 12 starts to rotate after receiving the power, and drives the cutter 6 thereon to rotate at a high speed. The cutter 6 contacts the road surface during the rotation process, and applies a cutting force to cut the road surface material into a desired shape and size. The servo motor 10 drives the first sprocket 13 and the first chain 14 to transmit power to the rectangular seat 12 and the cutter 6, so that the high-speed rotation and cutting of the cutter 6 are achieved. Cutting operation, this power transmission method makes the cutting operation more efficient and faster, the design of the mounting block 11 and the rectangular seat 12 ensures the stability and reliability of the cutter 6 during the rotation process, and at the same time, the close engagement of the first sprocket 13 and the first chain 14 also reduces the energy loss and vibration during the power transmission process, and improves the stability and reliability of the entire cutting system. By adjusting the parameters such as the speed and torque of the servo motor 10, it can adapt to the cutting requirements of road surfaces of different materials and thicknesses. In addition, the design of the rectangular seat 12 and the cutter 6 can also be replaced and adjusted according to different cutting requirements.

[0041] In a further preferred embodiment of the present invention, a connecting plate 15 is fixedly installed on the top of the fixed plate 4, and the connecting plate 15 is arranged in an L shape. A first hydraulic cylinder 16 is installed on the connecting plate 3, and the output rod of the first hydraulic cylinder 16 is fixedly connected to the connecting plate 15. A guide rod 17 is installed on the top of the connecting plate 15, and the guide rod 17 slides through the connecting plate 3.

[0042] In this embodiment, when performing road finishing operations, when it is necessary to adjust the height of the cutter 6 (i.e., the upper and lower positions of the connecting plate 3), the control system will start the first hydraulic cylinder 16, and the output rod of the first hydraulic cylinder 16 will be extended and retracted, thereby pushing or pulling the connecting plate 15 to move up and down. At the same time, the guide rod 17 slides in the connecting plate 3 to ensure the stability and directionality of the connecting plate 15 during the movement. Through the cooperation of the first hydraulic cylinder 16 and the guide rod 17, the height adjustment function of the connecting plate 15 and the cutter 6 is realized. This design enables the cutter 6 to be adjusted in height according to different road conditions or finishing requirements, thereby improving the flexibility and adaptability of the operation. The design of the guide rod 17 ensures the stability and linearity of the connecting plate 15 during the up and down movement, thereby avoiding cutting errors or equipment damage caused by unstable movement. The height adjustment process is automatically completed by the first hydraulic cylinder 16 without manual intervention, thereby improving the degree of automation and efficiency of the operation.

[0043] In a further preferred embodiment of the present invention, a fixing block 19 is fixedly installed on one side of the mounting frame 5, and a second electric telescopic rod 20 is installed on one side of the fixing block 19. The output rod of the second electric telescopic rod 20 extends into the mounting frame 5 and is rotatably connected to the rectangular seat 12 away from the first sprocket 13.

[0044] In this embodiment, when the cutter 6 needs to be replaced, the cutter 6 can be replaced by controlling the extension and retraction of the second electric telescopic rod 20 so that its output rod drives the rectangular seat 12 away from the output rod of the cutter 6. The replacement is relatively quick. During this process, the servo motor 10 and the first sprocket 13 and other components remain stationary to ensure the safety and convenience of the replacement operation. The introduction of the second electric telescopic rod 20 makes the replacement of the cutter 6 quick and easy. The operator only needs to control the second electric telescopic rod 20 to easily remove the cutter 6 from the mounting frame 5, which greatly improves the replacement efficiency. Traditional replacement of the cutter 6 often requires manual disassembly of multiple parts, which is labor-intensive and time-consuming. The design of the present invention greatly simplifies the replacement process and reduces the labor intensity of the operator. The quick replacement of the cutter 6 means that the equipment can be restored to a working state more quickly, thereby improving the efficiency and continuity of the entire road cutting operation.

[0045] In a further preferred embodiment of the present invention, a fan-shaped plate 21 is fixedly installed on the U-shaped plate 2, and the fan-shaped plate 21 is located below the connecting plate 3. An arc groove 22 is opened on the top of the fan-shaped plate 21, and a support wheel 23 is installed on the bottom of the connecting plate 3, and the support wheel 23 is in contact with the arc groove 22.

[0046] The angle adjustment mechanism is used to adjust the rotation angle of the connecting plate 3 (and the cutter 6). The control system starts the angle adjustment mechanism, and the connecting plate 3 rotates around the rotation center of the U-shaped plate 2 under the action of the angle adjustment mechanism. At this time, the supporting wheel 23 rolls in the arc groove 22 to provide stable support and guidance for the rotation of the connecting plate 3. Since the shape of the arc groove 22 matches the supporting wheel 23, the rotation of the connecting plate 3 remains stable and accurate. The rolling contact design between the supporting wheel 23 and the arc groove 22 reduces friction and wear, making the connecting plate 3 more stable and smooth during rotation. The shape of the arc groove 22 limits the rolling trajectory of the supporting wheel 23, thereby ensuring the positioning accuracy of the connecting plate 3 during rotation. The design of the fan-shaped plate 21 and the supporting wheel 23 makes the entire rotating support mechanism compact and reasonable, reduces the occupied space, and makes the entire device more beautiful and tidy. Since the rolling contact design between the supporting wheel 23 and the arc groove 22 reduces wear, the maintenance cost of the entire rotating support mechanism is also relatively low.

[0047] In a further preferred embodiment of the present invention, a water tank 24 is fixedly installed on the top of the support plate 1, a water pump 25 is fixedly installed on one side of the inner wall of the water tank 24, a connecting pipe 26 is installed on the drainage end of the water pump 25, and the connecting pipe 26 extends out of the water tank 24 and is connected to the drainage pipe 18.

[0048] In this embodiment, when water spraying is required to reduce dust during road repair operations, the control system will start the water pump 25, which will draw out the liquid in the water tank 24 and send it into the connecting pipe 26 after pressurization. The connecting pipe 26 will transport the pressurized liquid to the drain pipe 18, so that the drain pipe 18 will spray the liquid in the form of mist to cover the repair operation area, thereby achieving the purpose of dust reduction and cleaning. The water spraying and dust reduction function can effectively reduce the impact of dust and debris generated during the repair process on the environment and workers, improve the cleanliness and safety of the working environment, and water spraying and dust reduction can reduce the adhesion of dust to equipment and tools, reduce the frequency of cleaning and maintenance, and thus improve work efficiency.

[0049] In a further preferred embodiment of the present invention, a U-shaped rod 27 is rotatably installed on the top of the U-shaped plate 2, and a plurality of straps 28 are provided on the U-shaped rod 27, and the plurality of straps 28 are all wound around the connecting tube 26. A bellows 29 is installed on one side of the U-shaped rod 27, and the connecting tube 26 passes through the bellows 29. A bracket 32 ​​is fixedly installed on the top of the U-shaped plate 2, and the bracket 32 ​​is rotatably connected to the U-shaped rod 27.

[0050] In this embodiment, during operation, when the connecting plate 3 is adjusting its angle, the U-shaped rod 27 rotates synchronously, so that the U-shaped rod 27 and the connecting plate 3 rotate synchronously, thereby ensuring that the connecting pipe 26 is always connected to the drain pipe 18. At the same time, the strap 28 firmly fixes the connecting pipe 26 on the U-shaped rod 27 to prevent it from falling off or shaking during rotation. The design of the bellows 29 enables the connecting pipe 26 to maintain a certain degree of flexibility during rotation and swinging. Through the design of the U-shaped rod 27 and the bracket 32, the flexibility of the connecting pipe 26 during operation is achieved. Adjustment, this design allows the connection 26 to rotate and swing according to actual needs to adapt to different working scenarios and angle requirements. The design of the strap 28 ensures the stability of the connecting pipe 26 during rotation and swinging. The strap 28 firmly fixes the connecting pipe 26 on the U-shaped rod 27 to prevent it from unnecessary movement or shaking, thereby ensuring the normal function of the water spray and dust reduction function. The design of the bellows provides effective dust protection for the connecting pipe. The design of the bellows 29 allows the connecting pipe 26 to maintain a certain flexibility when rotating and swinging.

[0051] In a further preferred embodiment of the present invention, a second sprocket 30 is fixedly mounted on the output rod of the connecting plate 3 and the U-shaped rod 27, a second chain 31 is mounted on a group of the second sprockets 30, the second chain 31 is meshed with a group of second sprockets 30, and a guide block is installed on the top of the U-shaped plate 2, and the guide block is slidably connected to the rack 9.

[0052] In this embodiment, when it is necessary to achieve synchronous rotation between the connecting plate 3 and the U-shaped rod 27, the control system will start the servo motor 10 to drive the connecting plate 3 to rotate. This rotational motion is transmitted to the second chain 31 through the second sprocket 30, and then transmitted to another second sprocket 30 by the second chain 31, thereby achieving synchronous rotation between the connecting plate 3 and the U-shaped rod 27. Through the transmission mechanism of the second sprocket 30 and the second chain 31, high-precision synchronous rotation between the connecting plate 3 and the U-shaped rod 27 is achieved. This synchronization mechanism reduces the synchronization deviation caused by mechanical errors and wear, and improves the operating accuracy and stability of the entire device. The design of the second sprocket 30 and the second chain 31 is compact and reasonable, which reduces the occupied space and makes the entire device more beautiful and tidy. At the same time, this compact structure is also convenient for maintenance and overhaul work. The second sprocket 30 and the second chain 31 have a high transmission efficiency, which can reduce energy loss and friction wear, and improve the transmission efficiency and service life of the entire device.

[0053] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0054] In another embodiment of the present invention, a support frame 33 is installed at the bottom of the support plate 1, a second hydraulic cylinder 34 is installed at the bottom of the support frame 33, and a crushing head 35 for crushing the road surface is provided below the second hydraulic cylinder 34.

[0055] In this embodiment, when the road surface needs to be crushed during the road surface finishing operation, the control system will start the second hydraulic cylinder 34, and the piston rod of the second hydraulic cylinder 34 will extend downward to push the crushing head 35 to move downward until it contacts the road surface. Subsequently, the second hydraulic cylinder 34 will continue to apply pressure to make the crushing head 35 apply a crushing force on the road surface. Under the crushing force of the crushing head 35, the road surface material is crushed into small pieces or particles, thereby realizing the crushing operation of the road surface. By introducing structures such as the crushing head 35, the present invention realizes the crushing operation function of the road surface finishing device on the road surface. The addition of this function enables the device to more comprehensively cope with different types of road surface finishing. The design of the crushing head 35 enables it to crush road materials efficiently. By adjusting the pressure parameters of the second hydraulic cylinder 34, it can realize fast and effective crushing of road materials of different hardness and thickness. Since the material and structural design of the crushing head 35 have certain flexibility, it can adapt to different types of road materials (such as asphalt, cement, etc.) and different crushing requirements (such as crushing depth, crushing particle size, etc.), which makes the device more adaptable and extensive in practical applications. The entire crushing operation process is automatically controlled by the control system without manual intervention or manual operation. This not only reduces the difficulty of operation and labor intensity, but also improves the safety and reliability of the operation.

[0056] In another embodiment of the present invention, a limit plate 36 is installed on the output rod of the second hydraulic cylinder 34, a T-shaped plate 37 is slidably installed on the bottom of the limit plate 36, the T-shaped plate 37 is fixedly connected to the crushing head 35, a connecting bolt 38 is threadedly installed on the limit plate 36, the connecting bolt 38 is threadedly connected to the T-shaped plate 37, a support plate 39 is installed on one side of the support plate 1, and the support plate 39 is connected to an external driving device.

[0057] In this embodiment, when performing a road crushing operation, the second hydraulic cylinder 34 drives its output rod to extend downward, pushing the limit plate 36 and the T-shaped plate 37 to descend together. The T-shaped plate 37 descends steadily under the guidance of the limit plate 36, and drives the crushing head 35 to contact the road surface. At this time, the external driving device drives the device to move through the support plate 39. During the movement, the second hydraulic cylinder 34 applies a crushing force to crush the road surface material into small pieces or particles. After the crushing operation is completed, the second hydraulic cylinder 34 drives its output rod to retract upward, driving the limit plate 36 and the T-shaped plate 37 to rise together, so that the crushing head 35 is separated from the road surface. By introducing structures such as the limit plate 36, the T-shaped plate 37 and the connecting bolts 38, a stable connection and lifting control between the crushing head 35 and the second hydraulic cylinder 34 are achieved. This connection method not only improves the stability and safety of the device, but also helps to extend the service life of the device. It is also convenient for disassembling and replacing the crushing head 35, which helps to reduce the maintenance cost and difficulty of the device and improves the reliability and availability of the device.
