[0024] 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.

[0025] like Figures 1 to 6As shown, this utility model proposes a sweeping and dust-blowing device for a road marking robot, including a moving mechanism 1. The moving mechanism 1 includes a chassis 11, on which a sweeping and dust-blowing mechanism 2 is mounted. The sweeping and dust-blowing mechanism 2 includes a sweeping mechanism 21 and a dust-blowing mechanism 22. The sweeping mechanism 21 is used to sweep the road surface, and the dust-blowing mechanism 22 is used to blow away particles from the road. The sweeping mechanism includes a connecting frame 211. A hinge rod 212 is mounted on one side of the connecting frame 211. One end of the hinge rod 212 is hinged to the connecting frame 211, and the other end of the hinge rod 212 is mounted with a motor 215. The motor 215 is a brushless geared motor, and a disc-type sweeping brush 216 is mounted on the rotor of the motor 215. A push-pull member 213, which is a cylinder, is hinged to one side of the hinge rod 212. One end of the push-pull member 213 is hinged to the connecting frame 211. The dust-blowing mechanism 22 includes a blower 221, with a baffle 222 fixedly connected to one side of the blower 221. A support frame 13 is provided on one side of the chassis 11, and the baffle 222 is mounted on the support frame 13. The moving mechanism 1 is the foundation of the entire device. It supports the entire sweeping and dust-blowing mechanism 2 through the chassis 11 and enables the device to move autonomously on the road. When the moving mechanism brings the sweeping and dust-blowing device to the designated position, the sweeping mechanism 21 starts to operate. The motor 215 drives the disc brush 216 to rotate and begin sweeping large particles of debris on the road. At the same time, the push-pull component 213 can adjust the angle of the brush and the ground pressure according to actual needs. If a greater sweeping force is required, the pitch angle can be increased to make the brush fit more closely to the ground, thereby increasing the friction between the brush and the ground; conversely, if the sweeping force is reduced, the pitch angle can be decreased to reduce the pressure of the brush on the ground. Following the sweeping, the blower 221 starts, generating a strong airflow to blow away fine particles and dust from the road surface, ensuring a clean and tidy surface. The blower 221 can adjust its speed in multiple levels to match the optimal airflow according to real-time needs. After completing the cleaning of a certain distance, the moving mechanism continues to move forward, repeating the above process until the cleaning task of the entire predetermined area is completed.

[0026] Furthermore, as a preferred embodiment of this utility model and not a limitation, a sleeve 12 is installed on one side of the chassis 11, and one end of the connecting frame 211 is fitted inside the sleeve 12. The sleeve 12 and the connecting frame 211 are slidably connected, and a first positioning pin for limiting the connecting frame 211 is provided on one side of the sleeve 12. The installation and disassembly of the connecting frame 211 and the sleeve 12 are simple and convenient. Specifically, the connecting frame 211 can be easily inserted into or pulled out of the sleeve 12 without complicated tools or steps, greatly simplifying the installation and disassembly process of the cleaning mechanism 21. The first positioning pin is inserted into the connecting frame 211 and the sleeve 12 to ensure that the connecting frame 211 will not slip out of the sleeve 12 due to vibration or other external forces during operation, thereby preventing the cleaning mechanism 21 from accidentally detaching from the chassis 11 and ensuring the safety and stability of the equipment operation. Even when encountering significant external force or impact during cleaning operations, the first positioning pin can firmly lock the connecting frame 211, ensuring that the cleaning mechanism 21 is securely fixed to the chassis 11 and will not fall off unexpectedly, thus guaranteeing the overall safety and reliability of the equipment.

[0027] Optionally, in some embodiments, a plug rod is installed on one side of the chassis 11, and the connecting frame 211 is provided with a cylinder for fitting the plug rod, and the cylinder is provided with a positioning pin for limiting the plug rod.

[0028] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, an inclined section 2222 is provided on one side of the baffle 222, and the fan 221 is installed on one side of the inclined section 2222. The design of the inclined section 2222 helps to more effectively guide the airflow generated by the fan 221, allowing it to blow onto the road surface at a more suitable angle. This not only enhances the ability to remove fine particles and dust, but also reduces airflow turbulence and improves cleaning efficiency.

[0029] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, a connector 214 is installed on one side of the motor 215. The connector 214 includes an L-shaped block 2141, and a connecting block 2143 on one side of the L-shaped block 2141. The connecting block 2143 has a through groove 2144 and an arc groove 2145. The hinge rod 212 has a through hole 2121 and a first through groove 2122. A rotating shaft 2146 is fitted inside the first through groove 2122. Both ends of the rotating shaft 2146 are located in the second through groove 2144. A second positioning pin is fitted inside the rotating shaft 2146. A bolt 2147 is fitted inside the through hole 2121. Both ends of the bolt 2147 are located in the arc groove 2145. A rotating shaft 2146 is fitted inside the first through groove 2122. The two ends of the rotating shaft are located within the second through groove 2144 of the connecting block 2143, allowing the hinge connector 214 to rotate or swing within a certain range around the rotating shaft 2146, thus adapting to different cleaning angle requirements. Bolts 2147 pass through the through hole 2121 of the hinge rod 212, with both ends located within the arc-shaped groove 2145 of the connecting block 2143. This ensures the hinge rod 212 is fixed while allowing it to move to a limited extent along the arc-shaped groove, thereby adjusting the angle of the disc brush 216. By screwing the corresponding nut into the bolt 2147, pressure is applied to the connecting block 2143, causing it to clamp the hinge rod 212, thus fixing the angle of the connecting block 2143 and ensuring that the disc brush 216 will not loosen due to vibration or other external forces during operation. The design of the second positioning pin effectively prevents the rotating shaft 2146 from sliding accidentally during operation, improving the overall reliability of the system. By removing the second positioning pin, the rotating shaft 2146 can be removed from the first through groove 2122, which makes it convenient for workers to remove the connector 214 and the components installed on it from one end of the hinge rod 212, facilitating maintenance.

[0030] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, support rods 2142 are fixedly connected to both sides of the L-shaped block 2141. The fixed connection to both sides of the L-shaped block 2141 increases the mechanical strength of the entire connector 214.

[0031] Example 1:

[0032] This utility model proposes a cleaning and dust-blowing device for a road marking robot, including a moving mechanism 1. The moving mechanism 1 includes a chassis 11, on which a cleaning and dust-blowing mechanism 2 is mounted.

The blower 221 can adjust its speed in multiple levels to match the optimal airflow according to real-time needs. After completing the cleaning of a certain distance, the moving mechanism continues to move forward, repeating the above process until the cleaning task of the entire predetermined area is completed.

[0033] A sleeve 12 is installed on one side of the chassis 11, and one end of the connecting frame 211 is fitted inside the sleeve 12. The sleeve 12 and the connecting frame 211 are slidably connected. A first positioning pin is provided on one side of the sleeve 12 to limit the connection frame 211. The installation and disassembly of the connecting frame 211 and the sleeve 12 are simple and convenient. Specifically, the connecting frame 211 can be easily inserted into or pulled out of the sleeve 12 without complicated tools or steps, greatly simplifying the installation and disassembly process of the cleaning mechanism 21. The first positioning pin is inserted into the connecting frame 211 and the sleeve 12 to ensure that the connecting frame 211 will not slip out of the sleeve 12 due to vibration or other external forces during operation, thereby preventing the cleaning mechanism 21 from accidentally detaching from the chassis 11 and ensuring the safety and stability of the equipment operation. Even if a large external force or impact is encountered during cleaning operations, the first positioning pin can firmly lock the connecting frame 211, ensuring that the cleaning mechanism 21 is firmly fixed to the chassis 11 and will not fall off accidentally, thus ensuring the overall safety and reliability of the equipment.

[0034] An inclined section 2222 is provided on one side of the baffle 222, and the fan 221 is installed on one side of the inclined section 2222. The design of the inclined section 2222 helps to more effectively guide the airflow generated by the fan 221, allowing it to blow onto the road surface at a more suitable angle. This not only enhances the ability to remove fine particles and dust, but also reduces airflow turbulence and improves cleaning efficiency.

[0035] A connector 214 is mounted on one side of the motor 215. The connector 214 includes an L-shaped block 2141 and a connecting block 2143 on one side of the L-shaped block 2141. The connecting block 2143 has a through groove 2144 and an arc-shaped groove 2145. The hinge rod 212 has a through hole 2121 and a first through groove 2122. A rotating shaft 2146 is fitted inside the first through groove 2122. Both ends of the rotating shaft 2146 are located in the second through groove 2144. A second positioning pin is fitted inside the rotating shaft 2146. A bolt 2147 is fitted inside the through hole 2121. Both ends of the bolt 2147 are located in the arc-shaped groove 2145.

Bolt 2147 passes through the through hole 2121 of hinge rod 212, and both ends are located in the arc groove 2145 of connecting block 2143. This ensures the fixation of hinge rod 212 while allowing it to move to a limited extent along the arc groove, thereby adjusting the angle of disc brush 216. By screwing the corresponding nut into bolt 2147, the connecting block 2143 is compressed, thereby clamping the hinge rod 212 and fixing the angle of connecting block 2143, ensuring that disc brush 216 will not loosen due to vibration or other external forces during operation. The design of the second positioning pin effectively prevents the shaft 2146 from accidentally sliding during operation, improving the overall reliability of the system. By removing the second positioning pin, the shaft 2146 can be removed from the first through groove 2122, making it convenient for workers to remove the connector 214 and the components installed on it from one end of hinge rod 212 for maintenance. Support rods 2142 are fixedly connected to both sides of L-shaped block 2141. Fixed to both sides of the L-shaped block 2141, increasing the mechanical strength of the entire connector 214.

[0036] Specifically, the working principle of this utility model is as follows:

[0037] The sweeping and dust-blowing device is driven autonomously along the road by the moving mechanism 1. Upon reaching the designated location, the motor 215 drives the disc brush 216 to rotate, beginning to sweep away large particles of debris on the road surface. The push-pull component 213 adjusts the angle of the brush and the ground pressure according to actual needs to adapt to different sweeping intensity requirements. This design ensures that the sweeping process is both flexible and efficient, closely adhering to the ground and providing sufficient friction to remove stubborn stains.

[0038] Following the sweeping, the blower 221 starts and generates a strong airflow, which blows fine particles and dust off the road surface through the inclined section 2222 on the baffle 222. The inclined section design allows the airflow to cover the road surface at a more suitable angle, reducing airflow scattering and improving cleaning efficiency. The blower 221 can be adjusted at multiple speeds according to real-time needs to match the optimal airflow and ensure that particles are thoroughly removed, thereby achieving a highly efficient dust blowing effect and ensuring that the road surface is clean and tidy.

[0039] To ensure the safety and stability of the equipment operation, a sleeve 12 is installed on one side of the chassis 11, with the connecting frame 211 slidably connected to it and locked by a first positioning pin to prevent the cleaning mechanism 21 from accidentally detaching from the chassis. Furthermore, the support rods 2142 fixedly connected to both sides of the L-shaped block 2141 enhance the overall mechanical strength. The design of the rotating shaft 2146 and the second positioning pin in the connecting piece 214 not only improves the reliability of the system but also facilitates the disassembly, assembly, and maintenance of components, making daily maintenance simpler and faster.

[0040] In summary, this utility model solves the problems of high dependence on manual labor, unstable cleaning effect and low efficiency of existing road cleaning methods.
