[0018] A construction method for an automatic crack sealing device for roads includes the following steps;

[0019] S1. Before crack sealing, the vehicle body is first moved to the designated position. Then, heating boxes one and two are started to heat the material. After that, the discharge pipe is started to begin crack sealing. Then, the road surface condition is detected by the monitoring sensor body. The main body controls motor one to drive the discharge pipe to move to different positions to treat cracks. At this time, after the discharge pipe moves, the sliding block will block the flow port to prevent material from still flowing out after the discharge pipe moves away from the flow port, reducing material waste. At the same time, the stability of the device is improved. Moreover, the degree of automation is high, and it can automatically treat cracks in different positions.

[0020] S2. When starting the crack filling process, material needs to be fed into heating box one. At this time, motor two is started, and motor two will rotate to make the two screw conveyors start rotating, and the material is fed into heating box one. At this time, when the screw conveyors rotate, the scraper will also move back and forth under the rotation of the reciprocating screw, scraping the material on the top wall of heating box two to avoid material waste.

[0021] S3. When both heating chamber 2 and heating chamber 1 start heating, the exhaust gas generated by the heating material will enter the buffer chamber, accumulate in the buffer chamber and gradually move upward. Then, the exhaust gas will enter the exhaust pipe 1 and enter the speed-changing pipe through the exhaust pipe 1. When the exhaust gas passes through the speed-changing pipe, it is compressed and forms a high-speed flow. After entering the exhaust pipe 2, the speed will not decrease. It will be blown out through the exhaust pipe 2 to pre-treat the ground, blowing out dust and other debris from the cracks. In addition, the exhaust gas has a high temperature. If there are trace amounts of water stains in the cracks, they will be dried quickly, providing good working conditions for grouting.

[0022] Compared with the prior art, the present invention provides an automatic crack sealing device and construction method for roads, which has the following beneficial effects:

[0023] 1. When sealing cracks in the road surface, the discharge pipe is activated to seal the cracks. When sealing cracks in different locations, the position of the discharge pipe is moved through the sealing mechanism, allowing the discharge pipe to treat different locations of the road surface without manual intervention. This improves the flexibility of the device and enhances its automation, reducing the workload of workers.

[0024] 2. When the storage box moves the discharge pipe, the sliding block will block the bottom of the flow port through the crack filling mechanism, so that the flow port will not continue to feed material downward as the storage box leaves, which improves the stability of the device and avoids material waste, making the device more suitable for crack filling.

[0025] 3. When feeding heating box one, start motor two. Through the feeding mechanism, the two augers will start to rotate and feed heating box one through the through groove. The raw materials adhering to the inner wall of heating box two will flow down through guide plate one into the feeding box. In addition, the raw materials at the top of heating box two will be scraped off by scraper, which improves the utilization rate of materials.

[0026] 4. When heating begins inside heating box one, exhaust gas is generated. The exhaust gas enters the buffer box through heating box two, and then enters the exhaust pipe one. After passing through motor two, it will start to accelerate and be discharged through exhaust pipe two at a high speed to treat the road surface, blow away debris in the cracks, improve the utilization rate of exhaust gas and reduce energy waste.

[0036] 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.

[0037] Example:

[0038] Please see Figure 1 - Figure 8 This embodiment of an automatic road crack sealing device and its construction method includes a vehicle body 1, a heating box 2 on the top of the vehicle body 1, a flow port 3 at the bottom of the heating box 2, the flow port 3 being connected to the bottom of the vehicle body 1, a sealing mechanism on the vehicle body 1 via the heating box 2, a second heating box 20 on the top of the vehicle body 1, a feeding mechanism on the vehicle body 1 via the second heating box 20, a buffer box 33 on the top of the second heating box 20, and auxiliary components on the second heating box 20 via the buffer box 33.

[0039] The crack filling mechanism includes a limiting frame 4 set at the bottom of the vehicle body 1, a sliding plate 5 set inside the limiting frame 4, a storage box 6 set at the bottom of the vehicle body 1, a sliding block 8 set at the bottom of the vehicle body 1, a threaded rod 18 set on the side of the limiting frame 4, and a motor 19 for driving set on the side of the limiting frame 4.

[0040] The feeding mechanism includes an auger 21 installed inside the heating box 20, a rotating shaft 22 installed on the side of the auger 21, and a reciprocating screw 29 installed on the side of the heating box 20.

[0041] The auxiliary components include an air outlet pipe 34 located above the buffer box 33, a monitoring sensor body 37 located on the side of the vehicle body 1, and a main body 38 located at the bottom of the vehicle body 1.

[0042] In the process of filling the cracks, firstly, vehicle 1 is started and moved to the designated position. Vehicle 1 consists of steering wheels, a platform, a transmission mechanism, and drive wheels. Its function is to move the device to the designated position and to perform steering and other movements as needed. Vehicle 1 is a well-known and mature technology in the art, therefore it is not described in detail in this embodiment, nor is it shown in detail in the accompanying drawings. Vehicle 1 will move the device to the designated position. Then, heating boxes 1 and 2 are activated. Heating boxes 1 and 2 are both sealed boxes, heating machines, heating plates, and batteries. Their function is to heat the interior. Heating boxes 1 and 2 are well-known and mature technologies in the art, therefore they are not described in detail in this embodiment, nor are they shown in detail in the accompanying drawings. The accompanying drawings of this embodiment illustrate the process. After heating in heating chamber 1 2 and heating chamber 2 20, the raw materials inside become liquid. Then, the feeding mechanism is activated to feed the liquefied raw materials into heating chamber 1 2. Afterward, the raw materials flow into the receiving box 6 through the flow port 3. After the discharge pipe 7 is aligned with the crack, the discharge pipe 7 is activated. The discharge pipe 7 consists of a pressure booster, a pipe, and an automatic switch. Its function is to squeeze the raw materials into the crack. The discharge pipe 7 is a well-known and mature technology in the art, so it will not be described in detail in this embodiment. The discharge pipe 7 squeezes the raw materials in heating chamber 1 2 into the crack to fill it. When it is necessary to fill cracks in different locations, the filling mechanism is activated to adjust the position of the discharge pipe 7 so that the discharge pipe 7 automatically fills cracks in different locations.

[0043] At this point, the cracks were filled. The device is highly automated and can automatically fill cracks in different locations. This automation reduces human intervention, eliminating the need for staff to assist in the filling process. This reduces the risk of burns to workers from heated raw materials and also minimizes the risk of workers inhaling harmful substances, ensuring their safety. Furthermore, the elimination of the need for heavy protective equipment reduces the workload for workers and improves efficiency.

[0044] The grouting mechanism also includes a baffle 9 at the bottom of the sliding block 8, a spring 10 on the side of the baffle 9, magnets 11 on opposite sides of the storage box 6, two sliding blocks 8, magnets 22 on the side of the two sliding blocks 8 that are close to each other, at least two limiting grooves 13 at the bottom of the heating box 2, limiting blocks 14 inside the limiting grooves 13, a sliding groove 15 at the top of the sliding block 8, a spring 26 inside the sliding groove 15, a limiting block 27 inside the sliding groove 15, and a discharge pipe 7 at the bottom of the storage box 6.

[0045] The top of the limiting frame 4 is fixedly connected to the bottom of the vehicle body 1. There are two sliding plates 5, which are symmetrically distributed. The sides of the sliding plates 5 are slidably connected to the inner wall of the limiting frame 4. The sides of the two sliding plates 5 that are close to each other are fixedly connected to the opposite sides of the storage box 6. The top of the storage box 6 is connected to the flow port 3. The top of the discharge pipe 7 is connected to the bottom of the storage box 6. Two sliding blocks 8 are located on the opposite sides of the storage box 6. The top of the sliding block 8 is slidably connected to the bottom of the vehicle body 1. The bottom of the sliding block 8 is fixedly connected to the top of the baffle 9. One end of the spring 10 is fixedly connected to the side of the baffle 9.

[0046] The other end of spring 10 is fixedly connected to the side of storage box 6, the side of magnet block 11 is fixedly connected to the side of storage box 6, the side of magnet block 212 is fixedly connected to the side of sliding block 8, magnet block 212 and magnet block 11 are magnetically attracted, the limiting groove 13 and the sliding groove 15 are located on the same axis, the limiting block 217 and the sliding groove 15 are slidably connected, one side of the limiting block 217 is an inclined surface, one side of the limiting block 14 is an inclined surface, and the inclined surfaces of the limiting block 14 and the limiting block 217 are matched.

[0047] The bottom of the second limiting block 17 is fixedly connected to the top of the second spring 16, the bottom of the second spring 16 is fixedly connected to the inner bottom wall of the slide groove 15, one end of the threaded rod 18 passes through the limiting frame 4, the threaded rod 18 is rotatably connected to the limiting frame 4, one end of the threaded rod 18 passes through the sliding plate 5, the threaded rod 18 is threadedly connected to the sliding plate 5, and the other end of the threaded rod 18 is fixedly connected to the output end of the first motor 19.

[0048] Please refer to Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 6When filling cracks, the discharge pipe 7 is activated first, which transports the raw materials from the storage box 6 into the cracks. At this time, the heating box 2 transports the raw materials into the storage box 6 through the flow port 3. When cracks in different locations need to be filled, the motor 19 is activated, which drives the threaded rod 18 to rotate. Since the threaded rod 18 is threadedly connected to the sliding plate 5 and the sliding plate 5 is slidably connected to the limiting frame 4, the sliding plate 5 moves with the rotation of the threaded rod 18 under the limiting action of the limiting frame 4. As the sliding plate 5 moves, the storage box 6 moves along with it. At this time, the storage box 6 is connected to the sliding block 8 through the magnet 11 and the magnet 2 12. As the storage box 6 moves, the sliding block 8 on the opposite side of the movement trajectory also moves along with it. At this time, the chute 1... 5 will gradually approach the limiting groove 13. At this time, since the sliding block 8 is slidably connected to the bottom of the vehicle body 1, the limiting block 2 17 is squeezed into the sliding groove 15. At this time, the spring 2 16 is in a compressed state. When the sliding groove 15 reaches the bottom of the limiting groove 13, the upper part of the limiting block 2 17 loses the downward pressure force. At this time, the spring 2 16 will start to reset. Under the reset action of the spring 2 16, the limiting block 2 17 will start to slide in the sliding groove 15 and get stuck in the limiting groove 13. At this time, the inclined surface of the limiting block 2 17 will contact the inclined surface of the limiting block 1 14. At this time, the position of the sliding block 8 blocks the flow port 3, and the flow port 3 will not continue to convey raw materials downward. In addition, the position of the sliding block 8 is limited by the limiting block 2 17 and will not move with the storage box 6. At this time, the storage box 6 will continue to move, and the magnet block 1 11 and the magnet block 2 12 will separate.

[0049] The storage box 6 contains sufficient raw materials to continue supporting the discharge pipe 7 for grouting. As the storage box 6 moves, spring 10 gradually tightens, and spring 10 provides tension to the sliding block 8, ensuring it remains under pressure and doesn't easily move. The sliding block 8 remains against the flow port 3, preventing leakage of raw materials. When the storage box 6 begins to reset, the direction of rotation of motor 19 is controlled, and the storage box 6 moves back to its initial position. As the storage box 6 approaches the sliding block 8 against the flow port 3, spring 10 gradually returns to its normal state. When the storage box 6 reaches the side of the sliding block 8, magnet 11... Magnet block 2 12 will magnetically attract and fix the position between the storage box 6 and the sliding block 8. Then, as the storage box 6 continues to move, the inclined surface of the limiting block 2 17 will slide on the inclined surface of the limiting block 1 14. At this time, the limiting block 2 17 will move down and enter the slide groove 15. At this time, the spring 2 16 will gradually be in a compressed state as the limiting block 2 17 moves down. After the limiting block 2 17 enters the slide groove 15, the storage box 6 will drive the sliding block 8 to continue to move. At this time, the sliding block 8 will gradually leave the bottom of the flow port 3. After the sliding block 8 leaves, the top of the storage box 6 will be located at the bottom of the flow port 3. The flow port 3 will continue to replenish the storage box 6 with raw materials so that the discharge pipe 7 can continue to work.

[0050] At this point, the cracks are filled, and the discharge pipe 7 can be controlled to fill cracks in different locations, improving the flexibility and automation of the device. Conventional devices can only fill in one direction, and manual intervention is required in the other directions. However, this device can automatically fill the remaining locations, further reducing labor costs.

[0051] The feeding mechanism also includes two pulleys 23 located on the side of the heating box 20, with a belt 24 sleeved between the two pulleys 23, at least two pulleys 30 located on the side of the heating box 20, with a belt 31 sleeved between the two pulleys 30, a motor 25 located on the side of the heating box 20, at least two guide plates 27 located inside the heating box 20, a guide plate 28 located inside the heating box 20, a through groove 26 located on the side of the heating box 20, a slide rod 101 located inside the heating box 20, and a scraper 32 located inside the heating box 20.

[0052] There are two rotating shafts 22. One end of each rotating shaft 22 is fixedly connected to one end of each of the two augers 21. The other end of each rotating shaft 22 passes through the side of the heating chamber 20 and is rotatably connected to the heating chamber 20. One end of one rotating shaft 22 is fixedly connected to the output end of the motor 25. The outer walls of both rotating shafts 22 are fixedly connected to the pulleys 23. A reciprocating screw 29 passes through the heating chamber 20 and is rotatably connected to the heating chamber 20. The other rotating shaft 22 is connected to the reciprocating screw 23. The outer wall of the lead screw 29 is fixedly connected to the pulley 30, and the two ends of the slide rod 101 are fixedly connected to the inner wall of the heating box 20. The reciprocating lead screw 29 passes through the scraper 32 and is threadedly connected to the scraper 32. The slide rod 101 passes through the scraper 32 and is slidably connected to the scraper 32. The two guide plates 27 are symmetrically distributed. The side of the two guide plates 27 that is close to each other is an inclined surface. The side of the guide plate 28 that is close to the flow port 3 is an inclined surface. The through groove 26 is connected to the side of the heating box 2.

[0053] Please refer to Figure 1 , Figure 2 and Figure 8 When feeding material into heating chamber 2, motor 25 is started first. Motor 25 drives one of the rotating shafts 22 to rotate. When this rotating shaft 22 rotates, the pulley 23 on the other rotating shaft 22 drives the pulley 23 on the other rotating shaft 22 to rotate, causing both heating chambers 20 to rotate. Material is fed into heating chamber 2 through the through groove 26. At this time, since the raw material is adhesive, it will adhere to the inner wall of heating chamber 20. As heating chamber 20 heats up, the raw material will enter a liquefied state. The liquefied raw material will flow into the side of heating chamber 20 through the guide plate 27 and be fed through heating chamber 20, reducing material waste and facilitating cleaning after the work is completed. The raw material adhering to the top of heating chamber 20 will also be fed into heating chamber 20. The material enters a liquefied state after being heated and falls from the top of the heating box 20. However, some of the material cannot fall. At this time, as the rotating shaft 22 rotates, the pulley 30 on the rotating shaft 22 will drive the pulley 30 on the reciprocating screw 29 to rotate via the belt 24. The reciprocating screw 29 will start to rotate. The scraper 32 is threadedly connected to the reciprocating screw 29. Under the limiting action of the slide bar 101, the scraper 32 will move with the rotation of the reciprocating screw 29. Due to the characteristics of the reciprocating screw 29, the scraper 32 will move back and forth, scraping off the material at the top of the heating box 20 and allowing it to enter the feeding process, thus avoiding material waste. When the material enters the interior of the heating box 2 through the channel 26, it will enter the flow port 3 under the guiding action of the guide plate 28 and be transported to the collection box 6 to provide material for the discharge pipe 7.

[0054] At this time, material was fed into heating box 2. During the feeding process, material waste was avoided, the difficulty of material adhesion was solved, and the material could be fully put into operation. Moreover, this operation can be completed with only one power source, reducing energy waste and lowering production costs.

[0055] The auxiliary components also include a transmission pipe 35 located on the side of the first air outlet pipe 34, a second air outlet pipe 36 located on the side of the transmission pipe 35, an electric telescopic rod 39 located at the bottom of the vehicle body 1, a pressing plate 40 located below the electric telescopic rod 39, the bottom of the buffer box 33 connected to the top of the second heating box 20, the first air outlet pipe 34 and the second air outlet pipe 36 have the same cross-sectional radius, and the cross-sectional radius of the first air outlet pipe 34 is larger than that of the transmission pipe 35.

[0056] One end of the air outlet pipe 34 is connected to the top of the buffer box 33, and the other end of the air outlet pipe 34 is connected to one end of the buffer box 33. The other end of the buffer box 33 is connected to one end of the air outlet pipe 36. The top of the electric telescopic rod 39 is fixedly connected to the bottom of the vehicle body 1. The top of the pressing plate 40 is fixedly connected to the output end of the electric telescopic rod 39. The main body 38 is electrically connected to the monitoring sensor body 37. The main body 38 is electrically connected to the electric telescopic rod 39. The main body 38 is electrically connected to the motor 19.

[0057] Please refer to Figure 1 , Figure 2 and Figure 3 When heating the materials in heating chamber 20 and heating chamber 2, waste gas is generated during heating. This waste gas needs to be discharged. At this time, the waste gas in heating chamber 2 enters heating chamber 20 through channel 26, and then enters buffer chamber 33 through heating chamber 20. At this time, the waste gas begins to accumulate in buffer chamber 33 and gradually moves upward. Then, the waste gas enters exhaust pipe 34. At this time, the movement speed of the waste gas is low. When the waste gas begins to move in exhaust pipe 34, it enters speed change pipe 35. At this time, the waste gas passes through exhaust pipe 34. After entering the transmission tube 35, the exhaust gas is compressed, increasing its flow velocity. When it enters the second exhaust pipe 36 through the transmission tube 35, the exhaust gas velocity does not decrease but continues to increase as it rushes out of the second exhaust pipe 36. Since the exhaust gas is generated by heating the raw materials, it still contains high heat. When it is blown out through the second exhaust pipe 36, the high speed and strong impact force will blow sand and other debris out of the crack. Furthermore, if there are small water stains in the crack, they will be quickly evaporated by the heat flow in the exhaust gas, providing a good environment for filling the crack.

[0058] The overall component 38, model YL-235, consists of a power distribution unit, a PLC programmable controller, a touch screen, a frequency converter, a stepper motor controller, a servo motor controller, buttons and indicator lights, wiring terminals, and various detection sensors. Its function is to receive signals and transmit them to the power source, controlling the power source to start or stop. Furthermore, overall component 38 is a well-known and mature technology in the art, therefore it will not be described in detail in this embodiment, nor is it shown in detail in the accompanying drawings. The monitoring sensor body 37, model RS-LMK-N01 / 4G-1, mainly consists of a laser light source, a filter device, a lens, a DC power supply circuit, and a heating device. Its function is to... The information on ground cracks is collected and transmitted to the main body 38. The monitoring sensor body 37 is a well-known and mature technology in the art, so it is not described in detail in this embodiment, nor is it shown in detail in the accompanying drawings. The main body 38 controls the motor 19 to rotate and controls the direction of rotation of the motor 19 according to the signal of the monitoring sensor body 37, so as to drive the discharge pipe 7 to fill cracks in different directions. The main body 38 controls the electric telescopic rod 39 to move. After the discharge pipe 7 has finished filling cracks, the electric telescopic rod 39 will drive the pressing plate 40 to move downwards, which, together with the movement of the vehicle body 1, will flatten the ground, improve the smoothness of the road surface, and improve the efficiency of the work.

[0059] At this time, the exhaust gas generated by heating in heating box 20 is utilized to blow and sweep the road surface, making the road surface that needs to be sealed clean in advance, which further improves the working efficiency of the device. In addition, due to the rational use of exhaust gas, energy consumption is also reduced.

[0060] This embodiment provides a construction method for an automatic road crack sealing device, which employs any of the automatic road crack sealing devices described in the above embodiments, including the following solutions;

[0061] S1. Before crack sealing, the vehicle body 1 is moved to the designated position. Then, heating box 1 2 and heating box 2 20 are started to heat the material. Then, the discharge pipe 7 is started to seal the crack. After that, the road surface condition is detected by the monitoring sensor body 37. The main body 38 controls the motor 19 to drive the discharge pipe 7 to move to a different position to treat cracks at different locations. At this time, after the discharge pipe 7 moves, the sliding block 8 will block the flow port 3 to prevent the flow port 3 from discharging material after the discharge pipe 7 moves away from the flow port 3, thus reducing material waste. At the same time, the stability of the device is improved. Moreover, the degree of automation is high, and it can automatically treat cracks at different locations.

[0062] S2. When the crack filling treatment begins, material needs to be fed into the heating box 2. At this time, the motor 25 is started. The motor 25 will rotate and the two screw conveyors 21 will start to rotate to feed the material into the heating box 2. At this time, when the screw conveyors 21 rotate, the scraper 32 will also move back and forth under the rotation of the reciprocating screw 29 to scrape the material on the top wall of the heating box 20 to avoid material waste.

[0063] S3. When both heating chamber 20 and heating chamber 2 start heating, the exhaust gas generated by the heating material will enter the buffer chamber 33, accumulate in the buffer chamber 33 and gradually move upward. Then, the exhaust gas will enter the exhaust pipe 34 and enter the speed change pipe 35. When the exhaust gas passes through the speed change pipe 35, it is compressed and forms a high-speed flow. After entering the exhaust pipe 36, the speed will not decrease. It will be blown out through the exhaust pipe 36 to pre-treat the ground and blow out dust and other debris from the cracks. In addition, the exhaust gas has a high temperature. If there is a small amount of water in the crack, it will be dried quickly, providing good working conditions for grouting.

[0064] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0065] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
