Description

Technical Field

[0001] This invention belongs to the field of road repair technology, and relates to a hot-melt repair mechanism for road cracks and an adaptive paving and leveling equipment and method. Background Technology

[0002] Hot-melt crack repair is a highly efficient and reliable crack repair technology widely used in engineering fields such as roads and bridges. By using hot-melt materials, which possess strong adhesion and high elasticity, it can penetrate deep into the crack, tightly wrapping it and firmly bonding with the materials on both sides to form a robust protective layer. Its excellent sealing performance effectively prevents the intrusion of moisture, air, and debris, protecting structural safety. Repair requires the use of specialized repair equipment.

[0003] A search revealed a portable road crack repair machine disclosed in announcement number CN116905328A, which includes an insulated outer shell and a hot melt kettle. Although the above device can stir the asphalt molten liquid during use, the road surface is poorly cleaned before repair, affecting the adhesion between the asphalt solution and the ground. Therefore, we propose a hot melt repair mechanism for road cracks and an adaptive paving and leveling equipment and method to solve the above-mentioned problems. Summary of the Invention

[0004] In view of this, in order to solve the problem that poor road surface cleaning before repair affects the adhesion between asphalt solution and the ground, the present invention provides a hot-melt repair mechanism for road cracks and an adaptive paving and leveling equipment and method.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hot-melt repair mechanism for road cracks and an adaptive paving and leveling device, comprising a vehicle body, a mixing tank fixedly connected to the surface of the vehicle body, a mounting frame fixedly connected to one side of the vehicle body, a mounting box fixedly connected to the surface of the mounting frame, an inclined guide plate fixedly connected between the inner walls of the two sides of the mounting box, a through exhaust pipe fixedly connected to the bottom of the mounting frame, the top of the exhaust pipe passing through the mounting box and the guide plate, a filter box fixedly connected to the top inner wall of the mounting box, a fan fixedly connected to the top of the mounting box, the exhaust end of the fan being fixedly connected to the filter box via a pipe, an exhaust box fixedly connected to the bottom inner wall of the mounting frame, the bottom of the exhaust pipe being fixedly connected to the exhaust box, and the guide plate separating the cavity inside the mounting box to separate dust from solids;

[0006] A discharge assembly, which is located at the bottom of the installation box, is used to discharge impurities guided down by the guide plate;

[0007] A filter assembly, which is disposed within a filter box for filtering dust.

[0008] Furthermore, a through drive shaft is rotatably connected between the two sides of the mounting bracket, and two symmetrically arranged rollers are fixedly connected to the circumference of the drive shaft. A second motor is fixedly connected to the top of the mounting bracket, and a fixed shaft is fixedly connected to one end of the output shaft of the second motor. The fixed shaft and the drive shaft are driven by a sprocket and chain.

[0009] Furthermore, the discharge assembly includes a discharge box, which is fixedly connected to the bottom of the mounting box and has an open bottom. The bottom of the discharge box is fixedly connected to a mounting shaft, and the mounting shaft is rotatably connected to a baffle for sealing the bottom of the discharge box. Torsion springs are fixedly installed between both ends of the mounting shaft and the baffle.

[0010] Furthermore, the filter assembly includes a sliding frame that slides through the top of the mounting box, a pressure plate that is fixedly connected to the bottom of the sliding frame, a filter screen that is fixedly connected to the bottom of the pressure plate, a tension spring that is fixed between the pressure plate and the inner wall of the top of the mounting box by a hook, one end of the sliding frame extending to one side of the second motor and fixedly connected to a drive column, a drive plate that is fixedly connected to one side of the fixed shaft and cooperates with the drive column, and a collection box inserted into one side of the mounting box, the collection box being located below the filter screen.

[0011] Furthermore, a first motor is fixedly connected to the top of the mixing tank, and a through-type stirring shaft is rotatably connected to the top of the mixing tank. The stirring shaft is located inside the mixing tank, and one end of the output shaft of the first motor is fixed to the stirring shaft.

[0012] Furthermore, an air collection box is fixedly connected to the bottom of the vehicle body, the air collection box is located below the mixing tank, the air outlet of the blower is fixedly connected to an exhaust pipe, the exhaust pipe is fixedly connected to the air collection box, and the bottom of the air collection box is fixedly connected to multiple inclined nozzles.

[0013] Furthermore, an asphalt pump is fixedly connected to the surface of the vehicle body, and a discharge box is fixedly connected to the bottom of the vehicle body. The inlet end of the asphalt pump is fixedly connected to the mixing tank, and the outlet end of the asphalt pump is fixedly connected to the discharge box through a pipe.

[0014] Furthermore, a paving box is hinged to the bottom of the vehicle body, and two telescopic rods are rotatably connected between the bottom of the vehicle body and the paving box. A second spring is fixedly connected between both ends of the telescopic rods. Both sides of the mixing box are provided with drive assemblies for driving the paving box to swing. The drive assembly includes a drive disc, an intermediate shaft, and a crossbar fixed to one side of the paving box. The intermediate shaft is fixed to one side of the mixing box, and a swing plate is rotatably connected to the circumference of the intermediate shaft. A connecting rod is rotatably connected between one end of the swing plate and the crossbar. The drive disc is fixed to one end of the drive shaft, and multiple evenly distributed protrusions are fixedly connected to the circumference of the drive disc. One end of the swing plate is located below the drive disc and cooperates with the protrusions.

[0015] Furthermore, a control box, a diesel burner for heating asphalt, and a generator set for generating electricity are also fixedly connected to the surface of the vehicle body.

[0016] This invention also proposes a method for using a pavement crack hot-melt repair mechanism and an adaptive paving and leveling equipment, including the following steps:

[0017] S1. Start the second motor. The second motor drives the fixed shaft to rotate and drives the drive shaft to rotate through the sprocket and chain, thereby driving the roller to rotate and realize the movement of the vehicle body. At the same time, start the first motor. The first motor drives the mixing shaft to rotate and thus mix the asphalt. The asphalt in the mixing tank is heated by the diesel burner.

[0018] S2. During repair, start the fan. The fan draws air from the installation box to create negative pressure inside. Then, the foreign objects that need to be repaired enter the installation box through the exhaust box and exhaust pipe. Heavier foreign objects enter the discharge box with inertia and the guide plate, while lighter dust enters the filter box and is filtered by the filter screen under the suction of the fan.

[0019] S3. The air discharged from the blower is guided into the air collection box through the exhaust pipe and then sprayed out through the nozzle. The air collection box is located below the mixing tank. It uses the heat emitted from the mixing tank to heat the discharged air and then blow it onto the ground to dry the ground and improve the bonding effect between the asphalt and the ground.

[0020] S4. When the fixed shaft rotates, it also drives the drive plate to rotate. The drive plate drives the sliding frame to move downward through the drive column, which in turn causes the filter screen to move downward. Then the drive plate disengages from the drive column, and the filter screen is reset under the action of the tension spring. The inertia causes some of the dust on the filter screen to fall off, which facilitates the continuous operation of the filter screen and reduces the number of cleaning times.

[0021] S5. During repair, start the asphalt pump and lay the asphalt on the ground through the discharge box. The asphalt is then spread and leveled by the paving box. When the drive shaft rotates, it also drives the drive disc to rotate. The drive disc drives the protrusion to rotate, and the protrusion presses one end of the swing plate downward, which in turn causes the other end to lift one end of the paving box upward through the connecting rod. Then, under the action of the second spring, it moves downward, which causes the paving box to squeeze the laid asphalt up and down repeatedly, improving the paving effect.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. The pavement crack hot-melt repair mechanism and adaptive paving and leveling equipment disclosed in this invention, by installing a guide plate in the installation box, can separate foreign objects of different weights during pavement repair, avoid them from being concentrated together, reduce the number of manual cleanings, and improve the continuous use capacity and efficiency of the equipment.

[0024] 2. The road surface crack hot-melt repair mechanism and adaptive paving and leveling equipment disclosed in this invention, through the combined use of discharge box and baffle, enable heavier foreign objects to push open the baffle under the action of gravity when they are collected to a certain weight, thereby discharging the foreign objects to one side of the vehicle body, avoiding manual operation and improving efficiency.

[0025] 3. The pavement crack hot-melt repair mechanism and adaptive paving and leveling equipment disclosed in this invention, through the combined use of air collection box and nozzle, enable the air to dry the ground with the heat emitted from the mixing box when it is discharged, thereby improving the adhesion between asphalt and the ground.

[0026] 4. The pavement crack hot-melt repair mechanism and adaptive paving and leveling equipment disclosed in this invention, through the swaying setting of the paving box, can not only flatten the asphalt after it is laid, but also compact it, thereby improving the quality of the paving.

[0027] 5. The pavement crack hot-melt repair mechanism and adaptive paving and leveling equipment disclosed in this invention, through the movable setting of the filter screen, use inertia to make some of the dust on the filter screen fall off, which facilitates the continuous operation of the filter screen and reduces the number of cleaning times.

[0028] When repairing road surfaces, this invention can separate foreign objects of different weights to prevent them from accumulating together, reducing the number of manual cleaning operations and improving the continuous use and efficiency of the equipment. At the same time, when heavier foreign objects are collected to a certain weight, they can be pushed aside by gravity and discharged to one side of the vehicle body, avoiding manual operation and improving efficiency. It can also use the heat emitted from the mixing tank to dry the ground, improving the adhesion between the asphalt and the ground.

[0042] Example 1

[0043] like Figures 1-8 As shown, the road crack hot-melt repair mechanism and adaptive paving and leveling equipment include a vehicle body 1. A mixing tank 2 is fixedly connected to the surface of the vehicle body 1. A mounting frame 5 is fixedly connected to one side of the vehicle body 1. A mounting box 11 is fixedly connected to the surface of the mounting frame 5. Inclined guide plates 16 are fixedly connected between the inner walls of both sides of the mounting box 11. A through exhaust pipe 14 is fixedly connected to the bottom of the mounting frame 5. The top of the exhaust pipe 14 passes through the mounting box 11 and the guide plate 16, with the top of the exhaust pipe 14 facing the bottom of the guide plate 16. During dust removal, the inertia can be used to spray heavier items to one side, achieving separation of light and heavy items, avoiding concentration, reducing the number of manual cleanings, and improving the continuous use of the equipment. With capacity and efficiency, a filter box 21 is fixedly connected to the top inner wall of the mounting box 11, and a fan 10 is fixedly connected to the top of the mounting box 11. The exhaust end of the fan 10 is fixedly connected to the filter box 21 through a pipe. An exhaust box 15 is fixedly connected to the bottom inner wall of the mounting frame 5, and the bottom of the exhaust pipe 14 is fixedly connected to the exhaust box 15. The guide plate 16 separates the cavity inside the mounting box 11 to separate dust from solids. When the fan 10 is started, the fan 10 draws air from the mounting box 11 to create a negative pressure inside. Then, foreign objects that need to be repaired on the road enter the mounting box 11 through the exhaust box 15 and the exhaust pipe 14. Heavier foreign objects enter the discharge box 17 with inertia and the guidance of the guide plate 16.

[0044] The discharge assembly is located at the bottom of the mounting box 11 to discharge impurities guided by the guide plate 16;

[0045] A filter assembly is installed inside the filter box 21 to filter dust.

[0046] Example 2

[0047] Reference Figures 1-8 The present invention provides a new technical solution, a pavement crack hot-melt repair mechanism and an adaptive paving and leveling equipment, comprising:

[0048] In this invention, a through drive shaft 6 is rotatably connected between the two sides of the mounting frame 5. Two symmetrically arranged rollers 7 are fixedly connected to the circumference of the drive shaft 6. A second motor 12 is fixedly connected to the top of the mounting frame 5. A fixed shaft 13 is fixedly connected to one end of the output shaft of the second motor 12. The fixed shaft 13 and the drive shaft 6 are driven by a sprocket and chain. When the second motor 12 is started, the second motor 12 drives the fixed shaft 13 to rotate and drives the drive shaft 6 to rotate through the sprocket and chain, thereby driving the rollers 7 to rotate, so as to realize the movement of the vehicle body 1.

[0049] In particular, the discharge assembly includes a discharge box 17, which is fixedly connected to the bottom of the mounting box 11 and has an open bottom. The bottom of the discharge box 17 is fixedly connected to a mounting shaft 18, and the mounting shaft 18 is rotatably connected to a baffle 19 for sealing the bottom of the discharge box 17. Torsion springs 20 are fixedly installed between both ends of the mounting shaft 18 and the baffle 19. Through the cooperation of the discharge box 17 and the baffle 19, when a heavier foreign object is collected to a certain weight, it can push open the baffle 19 under the action of gravity, thereby discharging the foreign object to one side of the vehicle body 1, avoiding manual operation and improving efficiency.

[0050] It should be noted that the filter assembly includes a sliding frame 24 that slides through the top of the mounting box 11. A pressure plate 26 is fixedly connected to the bottom of the sliding frame 24, and a filter screen 23 is fixedly connected to the bottom of the pressure plate 26. A tension spring 25 is fixed between the pressure plate 26 and the inner wall of the top of the mounting box 11 via a hook. One end of the sliding frame 24 extends to one side of the second motor 12 and is fixedly connected to a drive column 33. A drive plate 34 is fixedly connected to one side of the fixed shaft 13 and works in conjunction with the drive column 33. A collection box 22 is inserted into one side of the mounting box 11. The collection box 22 is located below the filter screen 23. The drive plate 34 drives the sliding frame 24 to move downward through the drive column 33, thereby causing the filter screen 23 to move downward. Subsequently, the drive plate 34 disengages from the drive column 33, and the filter screen 23 resets under the action of the tension spring 25. The inertia causes some of the dust on the filter screen 23 to fall off, facilitating continuous operation of the filter screen 23 and reducing the frequency of cleaning.

[0051] In this invention, a first motor 3 is fixedly connected to the top of the mixing tank 2, and a through mixing shaft 4 is rotatably connected to the top of the mixing tank 2. The mixing shaft 4 is located inside the mixing tank 2, and one end of the output shaft of the first motor 3 is fixed to the mixing shaft 4. The mixing shaft 4 is driven to rotate by the first motor 3 to mix the asphalt.

[0052] In particular, a collection box 31 is fixedly connected to the bottom of the vehicle body 1. The collection box 31 is located below the mixing tank 2. The air outlet of the blower 10 is fixedly connected to an exhaust pipe 27. The exhaust pipe 27 is fixedly connected to the collection box 31. Multiple inclined nozzles 32 are fixedly connected to the bottom of the collection box 31. The air discharged by the blower 10 is guided by the exhaust pipe 27 and enters the collection box 31 and is then sprayed out through the nozzles 32. The collection box 31 is located below the mixing tank 2. It uses the heat emitted from the mixing tank 2 to heat the discharged air and then blow it to the ground to dry the ground and improve the subsequent bonding effect between the asphalt and the ground.

[0053] It should be noted that an asphalt pump 28 is fixedly connected to the surface of the vehicle body 1, and a discharge box 29 is fixedly connected to the bottom of the vehicle body 1. The inlet end of the asphalt pump 28 is fixedly connected to the mixing tank 2, and the outlet end of the asphalt pump 28 is fixedly connected to the discharge box 29 through a pipe. When the asphalt pump 28 is started, asphalt is laid on the ground through the discharge box 29.

[0054] In this invention, a paving box 30 is hinged to the bottom of the vehicle body 1. Two telescopic rods 41 are rotatably connected between the bottom of the vehicle body 1 and the paving box 30. A second spring 42 is fixedly connected between both ends of the telescopic rods 41. Both sides of the mixing tank 2 are provided with driving assemblies for driving the paving box 30 to swing. The driving assembly includes a driving disc 37, an intermediate shaft 35, and a crossbar 39 fixed to one side of the paving box 30. The intermediate shaft 35 is fixed to one side of the mixing tank 2. A swing plate 36 is rotatably connected to the circumference of the intermediate shaft 35. A connecting rod 40 is rotatably connected between one end of the swing plate 36 and the crossbar 39. 7 is fixed to one end of the drive shaft 6. Multiple evenly distributed protrusions 38 are fixedly connected to the circumference of the drive disc 37. One end of the swing plate 36 is located below the drive disc 37 and works in conjunction with the protrusions 38. When the drive shaft 6 rotates, it also drives the drive disc 37 to rotate. The drive disc 37 drives the protrusions 38 to rotate. The protrusions 38 press one end of the swing plate 36 downward, which causes the other end to lift one end of the paving box 30 upward through the connecting rod 40. Then, under the action of the second spring 42, it moves downward, which causes the paving box 30 to squeeze the paved asphalt up and down repeatedly, thereby improving the paving effect.

[0055] In particular, the surface of the vehicle body 1 is also fixedly connected to a control box 8, a diesel burner 43 for heating asphalt, and a generator set 9 for generating electricity.

[0056] This invention also proposes a method for using a pavement crack hot-melt repair mechanism and an adaptive paving and leveling equipment, including the following steps:

[0057] S1. Start the second motor 12. The second motor 12 drives the fixed shaft 13 to rotate and drives the drive shaft 6 to rotate through the sprocket and chain, which in turn drives the roller 7 to rotate, so as to make the vehicle body 1 move. At the same time, start the first motor 3. The first motor 3 drives the mixing shaft 4 to rotate, thereby mixing the asphalt. The asphalt in the mixing box 2 is heated by the diesel burner 43.

[0058] S2. During repair, start the blower 10. The blower 10 draws air from the mounting box 11 to create a negative pressure inside. Then, the foreign objects that need to be repaired enter the mounting box 11 through the exhaust box 15 and the exhaust pipe 14. Heavier foreign objects enter the discharge box 17 with inertia and the guidance of the guide plate 16, while lighter dust enters the filter box 21 under the suction of the blower 10 and is filtered by the filter screen 23.

[0059] S3. The air discharged from the blower 10 is guided by the exhaust pipe 27 and enters the air collection box 31, and then sprayed out through the nozzle 32. The air collection box 31 is located below the mixing box 2. The heat emitted from the mixing box 2 is used to heat the discharged air and then blow it to the ground to dry the ground and improve the subsequent bonding effect between the asphalt and the ground.

[0060] S4. When the fixed shaft 13 rotates, it also drives the drive plate 34 to rotate. The drive plate 34 drives the sliding frame 24 to move downward through the drive column 33, thereby causing the filter screen 23 to move downward. Then the drive plate 34 disengages from the drive column 33, and the filter screen 23 is reset under the action of the tension spring 25. The inertia causes some of the dust on the filter screen 23 to fall off, which facilitates the continuous operation of the filter screen 23 and reduces the number of cleaning times.

[0061] S5. During repair, the asphalt pump 28 is started, and asphalt is laid on the ground through the discharge box 29 and leveled by the paving box 30. When the drive shaft 6 rotates, it also drives the drive disc 37 to rotate. The drive disc 37 drives the protrusion 38 to rotate. The protrusion 38 presses one end of the swing plate 36 downward, which in turn causes the other end to lift one end of the paving box 30 upward through the connecting rod 40. Then, under the action of the second spring 42, it moves downward, which causes the paving box 30 to squeeze the laid asphalt up and down repeatedly, improving the paving effect.

[0062] The advantages of Example 2 over Example 1 are:

[0063] 1. By using the discharge box 17 and the baffle 19 together, when a heavier foreign object is collected to a certain weight, it can push open the baffle 19 under the action of gravity, thereby discharging the foreign object to one side of the vehicle body 1, avoiding manual operation and improving efficiency.

[0064] Second, by using the air collection box 31 and the nozzle 32 together, the air can be dried by the heat emitted from the mixing box 2 when it is discharged, thus improving the adhesion between the asphalt and the ground.

[0065] Third, the swaying setting of the paving box 30 allows the asphalt to be not only spread out but also compacted after paving, thus improving the quality of the paving.

[0066] However, as is well known to those skilled in the art, the working principles and wiring methods of the control box 8, diesel burner 43, generator set 9, first motor 3 and second motor 12 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.

The circumference of the intermediate shaft (35) is rotatably connected to the swing plate (36). One end of the swing plate (36) is rotatably connected to the crossbar (39) by a connecting rod (40). The drive disk (37) is fixed on one end of the drive shaft (6). The circumference of the drive disk (37) is fixedly connected to a plurality of evenly distributed protrusions (38). One end of the swing plate (36) is located below the drive disk (37) and cooperates with the protrusions (38).

9. The pavement crack hot-melt repair mechanism and adaptive paving and leveling equipment according to claim 1, characterized in that, The surface of the vehicle body (1) is also fixedly connected to a control box (8), a diesel burner (43) for heating asphalt, and a generator set (9) for generating electricity.

10. The method of using the pavement crack hot-melt repair mechanism and adaptive paving and leveling equipment according to any one of claims 1-9, characterized in that, Includes the following steps: S1. Start the second motor (12). The second motor (12) drives the fixed shaft (13) to rotate and drives the drive shaft (6) to rotate through the sprocket and chain, which in turn drives the roller (7) to rotate, so as to realize the movement of the vehicle body (1). At the same time, start the first motor (3). The first motor (3) drives the mixing shaft (4) to rotate, which in turn mixes the asphalt. The asphalt in the mixing box (2) is heated by the diesel burner (43). S2. When repairing, start the fan (10). The fan (10) draws air from the installation box (11) to create a negative pressure inside. Then, the foreign objects that need to be repaired enter the installation box (11) through the exhaust box (15) and the exhaust pipe (14). The heavier foreign objects enter the discharge box (17) with inertia and the guidance of the guide plate (16), while the lighter dust enters the filter box (21) under the attraction of the fan (10) and is filtered by the filter screen (23). S3. The air discharged by the blower (10) is guided by the exhaust pipe (27) and enters the air collection box (31) and is then sprayed out through the nozzle (32). The air collection box (31) is located below the mixing box (2). The heat emitted by the mixing box (2) is used to heat the discharged air and then blow it to the ground to dry the ground and improve the subsequent bonding effect between the asphalt and the ground. S4. When the fixed shaft (13) rotates, it also drives the drive plate (34) to rotate. The drive plate (34) drives the sliding frame (24) to move downward through the drive column (33), which in turn causes the filter screen (23) to move downward. Then the drive plate (34) disengages from the drive column (33), and the filter screen (23) is reset under the action of the tension spring (25). The inertia causes some of the dust on the filter screen (23) to fall off, which facilitates the continuous operation of the filter screen (23) and reduces the number of cleaning times. S5. During repair, start the asphalt pump (28), lay the asphalt on the ground through the discharge box (29), and flatten it through the paving box (30). When the drive shaft (6) rotates, it also drives the drive disc (37) to rotate. The drive disc (37) drives the protrusion (38) to rotate. The protrusion (38) presses one end of the swing plate (36) downward, so that the other end drives one end of the paving box (30) to lift upward through the connecting rod (40). Then, under the action of the second spring (42), it moves downward, so that the paving box (30) squeezes the laid asphalt up and down repeatedly, improving the paving effect.
