Description

Technical Field

[0001] The present invention relates to the technical field of pavement grouting, and in particular to a vehicle-mounted pavement grouting system and a use method thereof. Background Art

[0002] During the long-term use of highway pavement, due to the influence of factors such as traffic load and natural environment, cracks, potholes, and cracks will appear. These pavement diseases will not only affect driving safety and driving comfort, but also accelerate the aging and damage of the pavement. Timely repair and maintenance of highway pavement is the key to ensuring traffic safety and improving the service life of the pavement. Among highway pavement repair technologies, polymer grouting technology is an advanced repair method that has gradually received widespread attention and application. Polymer grouting technology refers to injecting polymer slurry materials into the diseased parts of the pavement to make it penetrate and fill cracks and gaps, react with the original pavement materials, and form a strong and stable repair layer. This repair method has the characteristics of rapidity, high efficiency, and durability, and plays an important role in repairing pavement cracks, potholes, cracks and other diseases.

[0003] The current grouting device has the following defects when in use: 1. In order to prevent the polymer slurry from solidifying during use, a stirring plate is generally added inside the storage cylinder to stir the polymer slurry, but some viscous polymer slurry will adhere to the stirring plate and the inner wall of the storage cylinder and cannot be discharged for use, which is not only inconvenient to clean, but also causes waste of raw materials; 2. After the polymer slurry is injected into the road, the accumulated water inside the road surface will overflow from the gaps in the road surface due to the squeezing of the polymer slurry, and some of the accumulated water will slowly seep into the gaps in the road surface and affect the road. Summary of the invention

[0014] As a preferred technical solution of the present application, the slurry discharge assembly includes a connecting sleeve rotatably mounted on the outside of the drill rod, a connecting pipe arranged between the connecting sleeve and the bottom of the slurry storage barrel, and a pressure pump arranged outside the slurry storage barrel, wherein a flow cavity is opened inside the connecting sleeve, the outer wall of the drill rod located inside the connecting sleeve is provided with a connecting port connected to the flow cavity, and a section of elastic bellows is provided in the middle of the connecting pipe.

[0015] As a preferred technical solution of the present application, the adsorption mechanism includes a second cylinder arranged on the side wall of the vehicle body, a fixed frame arranged at the bottom of the piston rod of the second cylinder, a mounting plate arranged on the fixed frame, a third motor arranged on the end face of the mounting plate, a screw arranged on the output shaft of the third motor, a movable sleeve threadedly arranged on the rod wall of the screw, a sliding rod arranged on the side wall of the movable sleeve and slidably connected to the side wall of the mounting plate, a reel rotatably arranged on the side wall of the mounting plate away from the third motor, cleaning cotton wound on the outside of the reel, a torsion spring sleeved on the rod wall of the reel between the cleaning cotton and the mounting plate, a roller arranged at the bottom of the mounting plate through a curved rod, and a support rod arranged at the bottom of the movable sleeve, wherein the end of the cleaning cotton away from the reel bypasses the lower surface of the roller and is fixedly connected to the bottom of the support rod.

[0016] As a preferred technical solution of the present application, the adsorption mechanism also includes a collection frame arranged at the bottom of the mounting plate, a first scraper arranged on the bottom wall of the collection frame, and a second scraper arranged on the top of the collection frame and cooperating with the first scraper, and the first scraper and the second scraper are in contact with the upper and lower surfaces of the cleaning cotton respectively.

[0017] The present invention also discloses a method for using the vehicle-mounted pavement grouting system, comprising the following steps:

[0018] S1: First, inject the polymer slurry into the slurry storage barrel, then start the first motor to stir the slurry in the slurry storage barrel through the stirring plate. At this time, the stirring plate will drive the rotating shaft on its top to rotate, and the rotating shaft will rotate along the driving gear on the stirring rod through the driven gear. Therefore, the rotating shaft will drive the screw to rotate through the driving bevel gear and the driven bevel gear, so that the cleaning sleeve can be driven to move along the surface of the stirring plate through the connecting block to scrape off the slurry attached to the surface of the stirring plate, and the scraper on the connecting rod can also be driven to rotate along the inner wall of the slurry storage barrel through the stirring rod, so as to scrape off the slurry attached to the inner wall of the slurry storage barrel;

[0019] S2: The first cylinder drives the second motor and the drill rod to move downward. At this time, the second motor is started to drive the drill rod to rotate and drill into the road surface. Then, the pressure pump pressurizes the inside of the slurry storage barrel, so that the slurry enters the flow cavity inside the connecting sleeve through the connecting pipe, and then enters the cavity inside the drill rod through the connecting port, and finally is injected into the road surface from the slurry outlet at the bottom of the drill rod;

[0020] S3: When the polymer slurry is injected into the road surface, the accumulated water inside the road surface will overflow under pressure. After the grouting is completed, the second cylinder is started to drive the mounting plate to move downward so that the cleaning cotton contacts the ground. Then the third motor is started to drive the screw rod to rotate, thereby driving the support rod to move horizontally and pulling the cleaning cotton out of the reel. At this time, the pulled cleaning cotton will contact and rub against the ground, thereby absorbing and cleaning the accumulated water.

[0021] S4: After the overflowed water is completely absorbed, the third motor drives the support rod to move in the opposite direction. At this time, the torsion spring is released from the force and drives the reel to reverse and reset, so that the cleaning cotton can be rolled up again. At this time, the cleaning cotton will pass between the first scraper blade and the second scraper blade. The first scraper blade and the second scraper blade can scrape the accumulated water stains on the surface of the cleaning cotton into the collection frame for collection.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] First, the polymer slurry is injected into the slurry storage barrel, and then the slurry can be reciprocatedly stirred by the arranged stirring mechanism to prevent the slurry from solidifying and affecting the grouting. At this time, through the arranged scraping mechanism, when the stirring rod and the stirring plate are rotating, the screw can also be driven to rotate by the rotating shaft, the driving gear, the driven gear, the driving bevel gear and the driven bevel gear. The screw will drive the cleaning sleeve to slide on the surface of the stirring plate through the connecting block, so as to facilitate the scraping of the slurry attached to the surface of the stirring plate during the stirring process. In addition, the arranged curved rod and scraper can also scrape the slurry attached to the inner wall of the slurry storage barrel, which solves the problem in the prior art that the residual slurry will adhere to the inner wall of the stirring plate and the slurry storage barrel and cannot be discharged, resulting in waste.

[0024] Through the grouting mechanism, the first cylinder and the second motor can be started at the same time to make the drill rod drill into the bottom of the road surface, and then through the slurry discharge assembly, the pressure pump is used to allow the slurry to enter the inside of the connecting sleeve through the connecting pipe, and then enter the drill rod through the connecting sleeve, and finally directly injected into the road surface through the drill rod. There is no need to drill a hole inside through the drill rod first, and then insert the grouting pipe into the hole for grouting, which saves time and increases the grouting speed.

[0025] After the slurry is injected into the road surface, the accumulated water inside the road surface will overflow onto the road surface due to pressure. When the grouting is completed, the third motor can be started through the adsorption mechanism, and the cleaning cotton can be pulled out from the reel through the screw rod, movable sleeve, sliding rod and support rod. The pulled out cleaning cotton will slide along the ground, so as to adsorb and clean the overflowed accumulated water, avoiding the overflowed accumulated water from affecting the injected slurry. Finally, the cleaning cotton is driven to move in the opposite direction by the third motor. At this time, the torsion spring can drive the reel to reverse and reset and rewind the cleaning cotton again.

[0026] When the cleaning cotton that has absorbed the accumulated water is rolled up in reverse, the cleaning cotton will pass between the first scraper blade and the second scraper blade. At this time, the accumulated water and stains sucked into the cleaning cotton can be scraped out by the first scraper blade and the second scraper blade, and the scraped accumulated water and stains will flow into the collecting frame along the first scraper blade and be collected, thereby keeping the cleaning cotton tidy and convenient for subsequent use.

DETAILED DESCRIPTION

[0041] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0042] like Figures 1 to 4 As shown, this embodiment proposes a vehicle-mounted road grouting system, including a vehicle body 1, a slurry storage barrel 2 arranged on the top of the vehicle body 1, a stirring mechanism arranged inside the slurry storage barrel 2, and a grouting mechanism arranged at the bottom of the vehicle body 1 and connected to the slurry storage barrel 2, and also includes a scraping mechanism and an adsorption mechanism. The scraping mechanism is arranged between the slurry storage barrel 2 and the stirring mechanism. The scraping mechanism can remove the slurry attached to the stirring mechanism and the inner wall of the slurry storage barrel 2 while the stirring mechanism stirs the slurry. The adsorption mechanism is arranged at the bottom of the vehicle body 1 and is used to clean and collect the accumulated water overflowing from the road surface due to grouting;

[0043] When it is necessary to inject polymer slurry into the gaps in the road surface for road surface maintenance, first open the barrel cover of the slurry storage barrel 2, add the polymer slurry into the barrel body, then drill holes in the road surface through the grouting mechanism, and then continue to perform grouting operations into the road surface. The slurry in the slurry storage barrel 2 can also be stirred by the stirring mechanism to prevent the slurry from being tightened and affecting the grouting. At the same time, part of the slurry attached to the stirring mechanism and the inner wall of the slurry storage barrel 2 can be scraped off by the scraping mechanism, which not only facilitates the cleaning of the equipment, but also enables all the slurry to be discharged to prevent the slurry from being wasted. Therefore, after the slurry is injected into the road surface, the accumulated water inside the road surface will be pressurized and overflow from the road surface. Therefore, after the grouting is completed, the overflowed accumulated water stains can also be cleaned and collected by the adsorption mechanism to prevent the accumulated water from seeping into the gap again and affecting the road surface.

[0044] Specifically, the stirring mechanism includes a first motor 3 arranged on the top of the slurry storage barrel 2, a stirring rod 301 arranged on the output shaft of the first motor 3, and a stirring plate 4 arranged on the rod wall of the stirring rod 301; starting the first motor 3 drives the stirring rod 301 connected to its output shaft to rotate reciprocatingly, and the stirring rod 301 will drive the stirring plate 4 to rotate back and forth to stir the slurry in the slurry storage barrel 2 to prevent the slurry from solidifying.

[0045] like Figure 4 , Figure 5 and Fig.10As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the scraping mechanism includes a shell 201 sleeved on the rod wall of the stirring rod 301, a screw 6 rotatably arranged on the side wall of the shell 201, a cleaning sleeve 5 slidably arranged on the outer wall of the stirring plate 4, and a connecting block 501 arranged on the top of the cleaning sleeve 5 and threadedly connected to the screw 6, wherein a transmission component for driving the screw 6 to rotate is also provided inside the shell 201;

[0046] The transmission assembly includes a rotating shaft 7 rotatably arranged on the top of the stirring plate 4 and extending to the inside of the housing 201, a driving bevel gear 701 and a driven gear 702 arranged on the rod wall of the rotating shaft 7, a driving gear 302 arranged on the top wall of the pulp storage barrel 2 and meshing with the driven gear 702, and a driven bevel gear 601 arranged at one end of the screw 6 located inside the housing 201 and meshing with the driving bevel gear 701;

[0047] When the stirring plate 4 rotates, it will drive the rotating shaft 7 on its top to rotate circumferentially along the stirring rod 301. At this time, the rotating shaft 7 will roll along the driving gear 302 through the driven gear 702. Therefore, the rotating shaft 7 will drive the screw 6 provided with the driven bevel gear 601 to rotate through the driving bevel gear 701, and the screw 6 will drive the cleaning sleeve 5 to slide on the surface of the stirring plate 4 through the connecting block 501, and the reciprocating stirring plate 4 will drive the cleaning sleeve 5 to slide reciprocatingly, so as to continuously scrape and clean the slurry attached to the surface of the stirring plate 4, which not only improves the cleanliness of the stirring plate 4, but also allows the slurry to fall completely and be discharged, saving slurry resources. It should be noted that the outer wall of the slurry storage barrel 2 is also provided with an observation window made of transparent material, and a scale mark is provided on the surface of the observation window, so that it is convenient for personnel to view the remaining slurry in the slurry storage barrel 2, and when adding polymer slurry, the amount of slurry added can be understood through the scale mark.

[0048] In addition, the scraping mechanism also includes a connecting rod 8 arranged on the rod wall near the bottom of the stirring rod 301 and a scraper 801 arranged at the end of the connecting rod 8 away from the stirring rod 301, and the scraper 801 is in contact with the inner wall of the slurry storage barrel 2; when the stirring rod 301 rotates, it will also drive the scraper 801 to rotate along the inner wall of the slurry storage barrel 2 through the connecting rod 8, so that the slurry attached to the inner wall of the slurry storage barrel 2 can also be scraped off, further improving the cleanliness of the equipment and saving resources.

[0049] like Figure 8 and Fig. 9 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the grouting mechanism includes a first cylinder 9 arranged at the bottom of the vehicle body 1, a second motor 901 arranged at the bottom of the piston rod of the first cylinder 9, and a drill rod 10 arranged at the end of the output shaft of the second motor 901, wherein a cavity is provided inside the drill rod 10, a grouting port is provided at the bottom of the drill rod 10, and a slurry discharge assembly for discharging slurry is provided between the drill rod 10 and the slurry storage barrel 2;

[0050] The slurry discharge assembly includes a connecting sleeve 11 rotatably sleeved on the outside of the drill rod 10, a connecting pipe 12 arranged between the connecting sleeve 11 and the bottom of the slurry storage barrel 2, and a pressure pump arranged outside the slurry storage barrel 2, wherein a flow cavity is opened inside the connecting sleeve 11, and an outer wall of the drill rod 10 located inside the connecting sleeve 11 is provided with a connecting port connected to the flow cavity, and a section of elastic bellows 1201 is provided in the middle of the connecting pipe 12;

[0051] After the polymer slurry is added to the slurry storage barrel 2, the first cylinder 9 can be started to drive the second motor 901 and the drill rod 10 to move downward. At this time, the second motor 901 is started again to drive the downward-moving drill rod 10 to rotate at a high speed, so that the drill rod 10 can drill into the road surface. At this time, the pressure pump is started to pressurize the inside of the slurry storage barrel 2. The pressurized slurry will first enter the flow cavity in the connecting sleeve 11 through the connecting pipe 12, and then continue to enter the cavity inside the drill rod 10 through the connecting port, and finally be directly injected into the road surface from the slurry outlet at the bottom of the drill rod 10. There is no need to drill a hole inside first, and then take out the drill rod 10 and insert it into the grouting pipe, which saves time and increases the grouting speed. In addition, the elastic bellows 1201 set can make the connecting pipe 12 stretch as the drill rod 10 moves downward, and the rotating drill rod 10 will not drive the connecting sleeve 11 to rotate accordingly, thereby not affecting the grouting.

[0052] like Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 , Fig.11 and Fig.12 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the adsorption mechanism includes a second cylinder 18 arranged on the side wall of the vehicle body 1, a fixing frame 1801 arranged at the bottom of the piston rod of the second cylinder 18, a mounting plate 13 arranged on the fixing frame 1801, a third motor 14 arranged on the end surface of the mounting plate 13, a screw rod 1401 arranged on the output shaft of the third motor 14, a movable sleeve 1402 threadedly arranged on the rod wall of the screw rod 1401, and a movable sleeve 1402 arranged on the side wall of the movable sleeve 1402 and slidingly connected to the side wall of the mounting plate 13. A sliding rod 1403 that is rotatably connected, a reel 15 that is rotatably arranged on the side wall of one end of the mounting plate 13 away from the third motor 14, a cleaning cotton 16 that is wound around the outside of the reel 15, a torsion spring 1501 that is sleeved on the rod wall of the reel 15 between the cleaning cotton 16 and the mounting plate 13, a roller 17 that is rotatably arranged at the bottom of the mounting plate 13 through a curved rod, and a support rod 1601 that is arranged at the bottom of the movable sleeve 1402, wherein one end of the cleaning cotton 16 that is away from the reel 15 passes around the lower surface of the roller 17 and is fixedly connected to the bottom of the support rod 1601;

[0053] The adsorption mechanism further includes a collection frame 19 disposed at the bottom of the mounting plate 13, a first scraper 1901 disposed on the inner bottom wall of the collection frame 19, and a second scraper 1902 disposed on the top of the collection frame 19 and cooperating with the first scraper 1901. The first scraper 1901 and the second scraper 1902 are in contact with the upper and lower surfaces of the cleaning cotton 16 respectively.

[0054] After the polymer slurry is injected into the road surface, the water originally accumulated in the road surface will overflow from the gap to the road surface due to the force. Therefore, after the grouting is completed, the second cylinder 18 is started first to drive the mounting plate 13 to move downward so that the cleaning cotton 16 contacts the ground, and then the third motor 14 is started to drive the screw rod 1401 to rotate. The screw rod 1401 will drive the support rod 1601 to move horizontally through the movable sleeve 1402 and pull out the cleaning cotton 16 wound on the reel 15. The cleaning cotton 16 will bypass the roller 17 and slide against the ground, thereby absorbing the overflowed accumulated water and stains, and preventing the overflowed accumulated water from seeping into the gaps in the road surface again. The road surface is affected, and finally the third motor 14 drives the lead screw 1401 to reverse, thereby driving the support rod 1601 to move in the opposite direction. At this time, the torsion spring 1501 is released from the force and drives the reel 15 to reverse and reset, and the reel 15 will reel up the cleaning cotton 16 again. Because the cleaning cotton 16 will slide between the first scraper 1901 and the second scraper 1902 when being pulled, the first scraper 1901 and the second scraper 1902 can scrape out the accumulated water and stains adsorbed on the surface of the cleaning cotton 16 and fall into the collection frame 19 along the first scraper 1901 to be collected, thereby keeping the cleaning cotton 16 tidy for subsequent use.

[0055] It should be noted that, in order to facilitate the staff to control the vehicle body 1 to move to a suitable position, a camera 20 with an angle tilted can be set at the bottom of the vehicle body 1, and a display screen 101 connected to the camera 20 signal can be installed on the top of the vehicle body 1. Therefore, the camera 20 can capture the picture of the road at the bottom of the vehicle body 1 and transmit it to the display screen 101 for the staff to see, thereby facilitating the staff to control the vehicle body 1 to move to the position where grouting is required.

[0056] The working principle of the present invention is as follows: when it is necessary to inject polymer slurry into the gaps of the road surface for road surface maintenance, first add the polymer slurry into the slurry storage barrel 2, then start the first cylinder 9 and the second motor 901 to work simultaneously, so that the drill rod 10 drills into the road surface, and then start the pressure pump to pressurize the inside of the slurry storage barrel 2. The pressurized slurry will first enter the flow cavity in the connecting sleeve 11 through the connecting pipe 12, and then continue to enter the cavity inside the drill rod 10 through the connecting port, and finally directly inject it into the road surface from the slurry outlet at the bottom of the drill rod 10. There is no need to drill a hole inside first, and then take out the drill rod 10 and insert it into the grouting pipe, which saves time and increases the grouting speed. At this time, the first motor 3 can also be started to drive the stirring rod 301 and the stirring plate 4 to rotate back and forth, stirring the slurry in the slurry storage barrel 2 to prevent the slurry from solidifying. When the stirring plate 4 rotates, it will drive the rotating shaft 7 on the top thereof to rotate along the circumferential direction of the stirring rod 301. At this time, the rotating shaft 7 will roll along the driving gear 302 through the driven gear 702, so the rotating shaft 7 will drive the screw 6 to rotate through the driving bevel gear 701 and the driven bevel gear 601, and the screw 6 will drive the cleaning sleeve 5 to slide on the surface of the stirring plate 4 through the connecting block 501, and the reciprocating stirring plate 4 will drive the cleaning sleeve 5 to slide back and forth, so as to continuously scrape and clean the slurry attached to the surface of the stirring plate 4. When the stirring rod 301 rotates, it will also drive the scraper 801 to rotate along the inner wall of the slurry storage barrel 2 through the connecting rod 8, so as to scrape off the slurry attached to the inner wall of the slurry storage barrel 2, further improving the cleanliness of the equipment and saving resources, so as to not only keep the cleanliness of the equipment, but also enable all the scraped slurry to be discharged, saving slurry resources. Because after the polymer slurry is injected into the road surface, the water originally accumulated in the road surface will overflow from the gap to the road surface due to the force. Therefore, after the grouting is completed, the second cylinder 18 is started to drive the mounting plate 13 to move downward so that the cleaning cotton 16 contacts the ground, and then the third motor 14 is started to work, and the support rod 1601 is driven to move horizontally through the screw rod 1401 and the movable sleeve 1402 to pull out the cleaning cotton 16 wound on the reel 15. The cleaning cotton 16 will bypass the roller 17 and slide on the ground, thereby absorbing the overflowed accumulated water and stains, and preventing the overflowed accumulated water from seeping into the gaps in the road surface again and causing damage to the road surface. Influence, and finally control the third motor 14 to drive the screw rod 1401 to reverse, so as to drive the support rod 1601 to move in the opposite direction. At this time, the torsion spring 1501 will be released from the force to drive the reel 15 to reverse and reset, and the reel 15 will reel up the cleaning cotton 16 again. Because the cleaning cotton 16 will slide between the first scraper 1901 and the second scraper 1902 when being pulled, the accumulated water and stains adsorbed on the surface of the cleaning cotton 16 can be scraped out by the first scraper 1901 and the second scraper 1902 and fall into the collection frame 19 along the first scraper 1901 to be collected, thereby keeping the cleaning cotton 16 tidy for subsequent use.

[0057] The present invention also discloses a method for using the vehicle-mounted pavement grouting system, comprising the following steps:

[0058] S1: First, inject the polymer slurry into the slurry storage barrel 2, and then start the first motor 3 to stir the slurry in the slurry storage barrel 2 through the stirring plate 4. At this time, the stirring plate 4 will drive the rotating shaft 7 on its top to rotate, and the rotating shaft 7 will rotate along the driving gear 302 on the stirring rod 301 through the driven gear 702. Therefore, the rotating shaft 7 will drive the screw 6 to rotate through the driving bevel gear 701 and the driven bevel gear 601, so that the cleaning sleeve 5 can be driven to move along the surface of the stirring plate 4 through the connecting block 501 to scrape off the slurry attached to the surface of the stirring plate 4, and the scraper 801 on the connecting rod 8 can also be driven to rotate along the inner wall of the slurry storage barrel 2 through the stirring rod 301, so as to scrape off the slurry attached to the inner wall of the slurry storage barrel 2;

[0059] S2: The first cylinder 9 is operated to drive the second motor 901 and the drill rod 10 to move downward. At this time, the second motor 901 is started to drive the drill rod 10 to rotate and drill into the road surface. Then, the pressure pump is used to pressurize the inside of the slurry storage barrel 2, so that the slurry enters the flow cavity inside the connecting sleeve 11 through the connecting pipe 12, and then enters the cavity inside the drill rod 10 through the connecting port, and finally is injected into the road surface from the slurry outlet at the bottom of the drill rod 10;

[0060] S3: When the polymer slurry is injected into the road surface, the accumulated water inside the road surface will overflow under pressure. After the grouting is completed, the second cylinder 18 is started to drive the mounting plate 13 to move downward, so that the cleaning cotton 16 contacts the ground. Then the third motor 14 is started to drive the screw rod 1401 to rotate, so as to drive the support rod 1601 to move horizontally and pull the cleaning cotton 16 out of the reel 15. At this time, the pulled cleaning cotton 16 contacts and rubs with the ground, so as to absorb and clean the accumulated water.

[0061] S4: After the overflowed water is absorbed, the third motor 14 drives the support rod 1601 to move in the opposite direction. At this time, the torsion spring 1501 is released from the force and drives the reel 15 to reverse and reset, so that the cleaning cotton 16 can be rolled up again. At this time, the cleaning cotton 16 will pass through the first scraper 1901 and the second scraper 1902. The first scraper 1901 and the second scraper 1902 can scrape the accumulated water stains on the surface of the cleaning cotton 16 into the collection frame 19 for collection.

9. The method for using the vehicle-mounted road grouting system according to claim 8, characterized in that: The following steps are involved: S1: First, a polymer slurry is injected into the slurry storage barrel (2), and then the first motor (3) is started to work so as to stir the slurry in the slurry storage barrel (2) through the stirring plate (4). At this time, the stirring plate (4) drives the rotating shaft (7) on its top to rotate, and the rotating shaft (7) rotates along the driving gear (302) on the stirring rod (301) through the driven gear (702). Therefore, the rotating shaft (7) drives the screw (6) to rotate through the driving bevel gear (701) and the driven bevel gear (601), thereby driving the cleaning sleeve (5) to move along the surface of the stirring plate (4) through the connecting block (501) to scrape off the slurry attached to the surface of the stirring plate (4), and the stirring rod (301) can also drive the scraper (801) on the connecting rod (8) to rotate along the inner wall of the slurry storage barrel (2), thereby scraping off the slurry attached to the inner wall of the slurry storage barrel (2); S2: The first cylinder (9) is operated to drive the second motor (901) and the drill rod (10) to move downward, and then the second motor (901) is started to drive the drill rod (10) to rotate and drill into the road surface. Then, the pressure pump is used to pressurize the inside of the slurry storage barrel (2), so that the slurry enters the flow cavity inside the connecting sleeve (11) through the connecting pipe (12), and then enters the cavity inside the drill rod (10) through the connecting port, and finally is injected into the road surface from the slurry outlet at the bottom of the drill rod (10); S3: When the polymer slurry is injected into the road surface, the accumulated water inside the road surface will overflow under pressure. When the slurry injection is completed, the second cylinder (18) is first started to drive the mounting plate (13) to move downward, so that the cleaning cotton (16) contacts the ground. Then, the third motor (14) is started to drive the screw rod (1401) to rotate, thereby driving the support rod (1601) to move horizontally and pull the cleaning cotton (16) out of the reel (15). At this time, the pulled cleaning cotton (16) contacts and rubs against the ground, so that the accumulated water can be absorbed and cleaned. S4: After the overflowed accumulated water is completely absorbed, the third motor (14) drives the support rod (1601) to move in the opposite direction. At this time, the torsion spring (1501) is released from the force and drives the reel (15) to reverse and reset, so that the cleaning cotton (16) can be rolled up again. At this time, the cleaning cotton (16) passes between the first scraper (1901) and the second scraper (1902). The accumulated water stains attached to the surface of the cleaning cotton (16) can be scraped off by the first scraper (1901) and the second scraper (1902) and collected in the collection frame (19).
