DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the utility model are clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Example 1
[0027] Please see attached Figure 1-6 , the present embodiment is a highway marking removal device: comprising a driving vehicle 1, a debris collector 2 is rotatably connected to the bottom of the driving vehicle 1, a rotating frame 3 is provided on the side of the debris collector 2, a rotating shaft 4 is fixedly connected to the rotating frame 3, the rotating shaft 4 is rotatably connected to the driving vehicle 1, a liquid inlet pipe 5 is provided in the middle of the rotating shaft 4, a plurality of high-pressure nozzles 6 connected to the liquid inlet pipe 5 are provided at the bottom of the rotating frame 3, a first scraper 7 is fixedly connected to the rotating frame 3, a second scraper 8 is provided on the other side of the rotating frame 3, the second scraper 8 is fixedly connected to the driving vehicle 1, a cutting saw blade 9 is slidably connected to the second scraper 8, and a synchronization mechanism 10 for driving the rotating frame 3 and the cutting saw blade 9 to move synchronously is provided on the driving vehicle 1; the debris collector 2 comprises two symmetrically distributed rotating blocks 201, both of which are rotatably connected to the driving vehicle 1, and a plurality of elastic connecting rods 202 distributed at equal angles are fixedly connected between the two rotating blocks 201.
[0028] The debris collector 2 is located at the front side of the driving vehicle 1. The elastic connecting rod 202 is fixed on a circle of the rotating block 201. The elastic connecting rod 202 and the connecting block form an elliptical spherical structure. The elastic connecting rod 202 at the lower end of the debris collector 2 is in contact with the ground. When the debris collector 2 encounters gravel or stones as the driving vehicle 1 moves forward, the stones contact the elastic connecting rod 202. The reaction force of the stones on the elastic connecting rod 202 pushes the elastic connecting rod 202 to change direction, and the elastic connecting rod 202 is in contact with the ground. After the rod 202 is deformed, the space between the two elastic connecting rods 202 becomes larger, and the stone can enter the interior of the debris collector 2 from this gap. After the stone enters the interior of the debris collector 2, the elastic connecting rod 202 loses its function and returns to its initial state, preventing the stone in the debris collector 2 from rolling out, thereby cleaning the debris on the road surface and preventing the first scraper 7 and the second scraper 8 from colliding with the debris and causing the blade to curl. The rotating frame 3 is located at the rear side of the debris collector 2. After the device 2 cleans the gravel on the marking line, the rotating frame 3 processes the cleaned marking line. The bottom end of the first scraper 7 is lower than the lowest point of the rotating frame 3. The bottom ends of the first scraper 7 and the second scraper 8 are kept flush with the bottom end of the debris collector 2. The rotating shaft 4 can only rotate in one direction. The rotation of the rotating shaft 4 drives the rotating frame 3 to rotate in one direction. When the rotating frame 3 rotates in one direction, the high-pressure nozzle 6 at the bottom of the rotating frame 3 first cleans the marking line on the road. A part of the marking line will be directly cleaned under the action of the high-pressure water gun, and the part that cannot be cleaned will be scraped off by the first scraper 7. When the rotating frame 3 rotates, the driving vehicle 1 is in a forward state. In order to avoid that some marking lines cannot be cleaned, a second scraper 8 is also provided on the rear side of the driving vehicle 1. The second scraper 8 is slidably connected with a cutting saw blade. The cutting saw blade slides back and forth at high speed. The front side of the cutting saw blade is serrated. The second scraper 8 and the cutting saw blade are used to remove particularly stubborn marking lines to ensure the cleanliness of the marking line removal and reduce the damage to the road surface.
[0029] The front roller 11 and the rear roller 12 of the driving vehicle 1 can reduce the friction between the driving vehicle 1 and the ground, so as to facilitate the forward movement of the driving vehicle 1. The front roller 11 of the driving vehicle 1 can be vertically adjusted with the driving vehicle 1 through the slider 13. Under the action of the spring 15, the slider 13 is located at the lowest point of the slide groove. When the driving vehicle 1 is placed horizontally, the spring 15 ensures that the debris collector 2 can fit closely with the ground, thereby ensuring the debris collector 2 to collect gravel on the road surface. The guide rod 14 guides the vertical movement of the slider 13, and prevents the spring 15 from detaching from the upper end of the slider 13.
[0030] The protective cover 16 is located on the periphery of the rotating frame 3. A cushion layer is provided at the bottom of the protective cover 16. The cushion layer can increase the close contact between the protective cover 16 and the ground. The liquid extraction port on the upper side of the protective cover 16 is connected to a negative pressure pump. The water tank 17 and the booster pump 18 on the driving vehicle 1 pressurize the liquid and then spray it out through the connecting pipe 19 and the high-pressure nozzle 6. In order to avoid residual liquid and residues from marking cleaning on the road surface, sewage can be extracted through the negative pressure pump and the liquid extraction port to ensure the cleanliness of the road surface after cleaning.
[0031] The size of the first pulley 1001 is larger than that of the second pulley 1002. A driving motor is connected to the first pulley 1001, which is driven by the driving motor to rotate the first pulley 1001, and the first pulley 1001 drives the rotating shaft 4 and the rotating frame 3 to rotate synchronously. The rotation of the first pulley 1001 drives the second pulley 1002 to accelerate the rotation under the action of the connecting belt 1003, and the rotation of the second pulley 1002 drives the first connecting rod 1004 to rotate. The first connecting rod 1004, the second connecting rod 1005 and the cutting saw blade 9 constitute a crank slider 13 mechanism. Under the rotation of the first connecting rod 1004, the cutting saw blade 9 is driven by the second connecting rod 1005 to slide back and forth. The cutting saw blade 9 cuts the markings that are difficult to clean through the reciprocating sliding, thereby improving the cleaning ability of the road markings.
[0032] The handrail at the rear side of the driving vehicle 1 is used to manually push the handrail to move. Example 2
[0033] The structure is the same as the above embodiment. Figure 7 As shown, the specific difference of this embodiment is that a lifting frame 21 is fixedly connected to the rear side of the driving vehicle 1, and a trailer hook is fixedly connected to the rear end of the lifting frame 21.
[0034] One end of the lifting frame 21 is fixedly installed on the rear end of the driving vehicle 1, and the other end of the lifting frame 21 is installed with a trailer hook, which can be fixedly connected to the driving vehicle by bolts. During operation, the driving vehicle is driven to drive the movement of the driving vehicle 1, which reduces the user's labor and improves work efficiency. When not in use, the driving vehicle 1 can be lifted by the lifting frame 21. The driving vehicle and the lifting frame 21 adopt the lifting structure of a forklift and the front side of the forklift. Both of these are relatively mature existing technologies and will not be introduced in detail here.
[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
