Description

Technical Field

[0001] This invention relates to the field of asphalt spraying, and more particularly to a trailer-mounted asphalt spraying device and its construction process. Background Technology

[0002] Asphalt distributors are an important piece of construction equipment in highway maintenance, used for road repair and new pavement laying. Their main function is to evenly spray asphalt mixture onto the road surface to repair, seal, or lay the pavement, ensuring a tight bond between the asphalt surface layer and the non-asphalt base layer. This improves the structural strength and stability of the entire pavement and provides an effective protective layer for the base layer, extending the service life of the pavement. Asphalt distributors are an indispensable part of road construction and maintenance.

[0003] In existing technologies, the angle and position of the nozzles in asphalt spraying devices are fixed. However, since the asphalt spraying requirements vary in different road construction environments, if the spraying angle of the nozzles is fixed, construction personnel cannot quickly adjust the nozzle angle according to the site conditions, resulting in inaccurate control of the asphalt spraying area. Excessive or insufficient asphalt spraying will lead to asphalt waste, thereby increasing construction costs. If the spraying position of the nozzles is fixed, the range of asphalt spraying is limited, resulting in overlapping or uneven areas during the asphalt spraying process, which cannot achieve the ideal asphalt spraying effect. This uneven asphalt spraying will affect the quality and durability of the road. Summary of the Invention

[0004] (1) Technical problems to be solved

[0005] This invention addresses the issue that while the angle and position of the nozzles in an asphalt spraying device are fixed, the varying asphalt spraying requirements in different road construction environments present challenges. A fixed nozzle angle prevents workers from quickly adjusting it based on site conditions, leading to inaccurate control of the asphalt spraying area. Excessive or insufficient spraying results in wasted asphalt, increasing construction costs. Conversely, a fixed nozzle position limits the spraying range, causing overlapping or uneven areas and hindering the achievement of ideal asphalt spraying results. This uneven spraying negatively impacts road quality and durability. The technical problem this invention aims to solve is to provide a trailer-mounted asphalt spraying device and its construction process.

[0015] As a preferred embodiment, a construction process for a trailer-mounted asphalt spraying device includes the following steps:

[0016] S1. First, connect the equipment to the traction device via the traction frame. Then, use a wrench to remove the fixing bolts on the side of the feeding port, remove the sealing cap, and add asphalt into the tank. After the filling is completed, use a wrench to tighten the fixing bolts and seal the feeding port with the sealing cap. Then, start the traction device to move the equipment to the designated position via the steering wheel and the load-bearing wheel.

[0017] S2. After the equipment is moved to the designated position, adjust the width of the asphalt spraying area as needed, use the displacement mechanism to adjust the position of the nozzle, twist the displacement handle to drive the two positioning blocks to move in opposite directions, so that the displacement blocks drive the nozzle to slide on the outside of the displacement axis;

[0018] S3. After adjusting the position of the nozzle through the displacement mechanism, adjust the angle of the nozzle using the adjustment mechanism. Twist the locking handle to rotate 90 degrees to release the lock on the position of the trigger block. Rotate the adjustment handle to adjust the tilt angle of the nozzle. Press the locking handle down to make the trigger block and the clamping plate hug the adjustment shaft. Press down and twist the locking handle to rotate 90 degrees in the opposite direction to lock the position of the trigger block.

[0019] S4. Open the ball valve connecting the tank body to the three-way pipe, close the ball valve connecting the air passage pipe to the three-way pipe, start the drive mechanism through the control box, the drive mechanism drives the compression mechanism to draw in air and deliver it into the tank body, and the drive mechanism drives the stirring mechanism to heat and stir the asphalt in the tank body;

[0020] S5. Before asphalt spraying, the sweeping mechanism is lowered through the control box to sweep the area where asphalt spraying is to be carried out. The rotation of the load-bearing wheel drives the sweeping brush to rotate and sweep the designated area.

[0021] S6. After the asphalt spraying is completed, open the ball valve connecting the air pipeline and the three-way pipeline, close the ball valve connecting the tank and the three-way pipeline, and use compressed air to blow away the asphalt remaining at the nozzle. Then, use a traction device to move the equipment to the next area for asphalt spraying.

[0022] (3) Beneficial effects

[0023] 1. By setting up an adjustment mechanism, rotating the adjustment handle causes the displacement block to deflect to one side, which can quickly adjust the nozzle to a specified angle, accurately control the asphalt spraying area, avoid asphalt waste, and reduce road construction costs. Pressing down and turning the locking handle 90 degrees locks the trigger block in a specified position. The trigger block drives the two clamping plates to hold the adjustment shaft tightly, preventing the nozzle angle from deflecting during equipment movement, which would cause the asphalt spraying area to be inaccurately controlled. By setting up a displacement mechanism, turning the displacement handle 90 degrees causes the two positioning blocks to slide in opposite directions, which can adjust the nozzle position, accurately control the nozzle spraying range, avoid overlapping or uneven areas, meet the ideal asphalt spraying effect, and ensure the quality and durability of the road.

[0024] 2. By setting up a sweeping mechanism, the rotation of the lever wheel drives two sweeping brushes to sweep the area where asphalt needs to be sprayed, preventing garbage and impurities from affecting the bonding effect between the asphalt surface layer and the non-asphalt base material, and ensuring the structural strength and stability of the road surface; by setting up a compression mechanism, the rotation of two impellers forces air into the air intake, increasing the pressure inside the tank, making the asphalt spraying more uniform and avoiding inconsistent thickness; by setting up a mixing mechanism, the drive motor drives the mixing rod to rotate around the mixing shaft, and the heating box drives the heating wire inside the mixing rod to heat up, stirring and heating the asphalt inside the tank, preventing the asphalt from solidifying, and facilitating asphalt spraying.

Impellers 503 are fixedly connected to the outside of the compression shafts 502 and inside the housing 501. The two impellers 503 are meshed together. A gearbox 504 is fixedly connected to one side of the housing 501. The compression shaft 502 on the left side inside the gearbox 504 passes through the end of the housing 501 and is fixedly connected to... A compression gear 505 is connected to the gearbox 504. The right side of the compression shaft 502 passes through the end of the housing 501 and is fixedly connected to a driven gear 506. The compression gear 505 and the driven gear 506 are meshed. A circular through hole is opened on the upper surface of the housing 501. The circular through hole is fixedly connected to the lower branch of the three-way pipe 20. An air intake 508 is fixedly connected to the lower surface of the housing 501. Under the action of the compression gear 505 and the driven gear 506, the two impellers 503 rotate in opposite directions to draw air in through the air intake 508.

[0045] like Figure 7As shown, the mixing mechanism 11 includes two sealing columns 1101, which are rotatably connected to the middle of the left and right sides of the tank 1. A mixing shaft 1104 is fixedly connected to the middle of the opposite sides of the two sealing columns 1101. Six mixing rods 1103 are fixedly connected to the outer side of the sealing columns 1101. A heating wire is installed inside the mixing rod 1103. A heating box 1102 is rotatably connected to both ends of the mixing rod 1103. The heating box 1102 is fixedly connected to the side of the tank 1. The heating box 1102 drives the heating wire inside the mixing rod 1103 to heat up, thereby preventing the asphalt in the tank 1 from cooling down and solidifying.

[0046] like Figure 7 , Figure 8 As shown, the drive mechanism 12 includes a drive motor 1201, which is fixedly connected to the upper surface of the frame 7. Two drive pulleys 1202 are fixedly connected to the output end of the drive motor 1201. An agitator pulley 1205 is fixedly connected to the end of the agitator shaft 1104.

A second belt 1207 is sleeved on the outer side of the drive pulley 1202 and the compression pulley 1206 located inside the output end of the drive motor 1201.

[0047] When using this equipment, first connect the equipment to the traction device via the traction frame 703. Then, use a wrench to remove the fixing bolt 4 on the side of the feeding port 2, remove the sealing cap 3, and add asphalt into the tank 1. After filling, use a wrench to tighten the fixing bolt 4 and seal the feeding port 2 with the sealing cap 3. Then, start the traction device and move the equipment to the designated position via the steering wheel 702 and the load wheel 701. After the equipment is moved to the designated position, adjust the width of the asphalt spraying area as needed by adjusting the position of the nozzle 901 via the displacement mechanism 9. Control the asphalt spraying area as needed by adjusting the angle of the nozzle 901 via the adjustment mechanism 8. After the position and angle of the nozzle 901 are adjusted, first open the ball valve 13 connecting the tank 1 and the three-way pipe 20, and close the ball valve 13 connecting the air pipe 15 and the three-way pipe 20. Then, start the drive mechanism 12 via the control box 10. The drive mechanism 12 drives the compression mechanism 5 to draw in air and deliver it into the tank 1. The mixing mechanism 11 heats and stirs the asphalt in the tank 1, preventing it from solidifying and becoming unsprayable. When the pressure inside the tank 1 rises to a certain value, the asphalt in the tank 1 enters the conveying pipe 17 through the discharge pipe 16, and then is sprayed out from the nozzle 901 through the conveying pipe 17 to spray the area where asphalt needs to be sprayed. The traction device is used to move the equipment forward. The cleaning mechanism 6 is lowered through the control box 10. The cleaning mechanism 6 cleans the area where asphalt needs to be sprayed to prevent garbage and impurities from affecting the bonding effect between the asphalt surface layer and the non-asphalt base material. After the spraying is completed, the ball valve 13 connecting the air pipeline 15 and the three-way pipeline 20 is opened first, and then the ball valve 13 connecting the tank 1 and the three-way pipeline 20 is closed. At this time, the pressure inside the tank 1 no longer rises, and the asphalt no longer flows to the nozzle 901. Compressed air blows away the asphalt remaining at the nozzle 901 to prevent the asphalt from solidifying and clogging the nozzle 901. At this time, the traction device can be used to move the equipment to the next area for asphalt spraying.

[0048] After the equipment is moved to the designated position, the position of the nozzle 901 is adjusted by the displacement mechanism 9. Pulling the displacement handle 904 upward causes the displacement column 905 to move upward, which in turn causes the limit block 906 to move upward. The upward movement of the displacement column 905 causes the pressure plate 910 to move upward, which in turn compresses the spring 909. After the limit block 906 disengages from the cross-shaped groove of the displacement block 903, twisting the displacement handle 904 rotates it 90 degrees to align it with the displacement shaft 806. This rotation of the displacement handle 904 causes the displacement column 905 to rotate 90 degrees, which in turn causes the support block 909 to rotate 90 degrees. Rotate 90 degrees. The support block 908 rotates 90 degrees, causing the arc surfaces at both ends to disengage from the positioning block 907. The displacement spring 911 releases pressure, pulling the two positioning blocks 907 towards each other within the square groove of the circular through hole on the side of the displacement block 903. The two positioning blocks 907 disengage from the square groove on the side of the elliptical through hole in the displacement shaft 806. Release the displacement handle 904. The compression spring 909 releases pressure, pushing the pressure plate 910 downward. The downward movement of the pressure plate 910 drives the displacement column 905 downward. The downward movement of the displacement column 905 causes the limiting block 906 to engage in the cross-shaped groove of the displacement block 903. At this time, the displacement block 903 can be moved to drive the nozzle 901 towards... After the nozzle 901 is adjusted to the designated position, the displacement handle 904 is pulled upwards. The upward movement of the displacement handle 904 drives the displacement column 905 upwards, which in turn drives the limit block 906 upwards. The upward movement of the displacement column 905 drives the pressure plate 910 upwards, which in turn compresses the spring 909. After the limit block 906 disengages from the cross-shaped groove of the displacement block 903, the displacement handle 904 is twisted 90 degrees to rotate 90 degrees to be perpendicular to the displacement axis 806. The support block 908 rotates 90 degrees to push the two positioning blocks 907 to slide in opposite directions within the square groove of the circular through hole on the side of the displacement block 903. The two positioning blocks slide in opposite directions. The tension displacement spring 911 and the two positioning blocks 907 slide in opposite directions into the square groove on the side of the elliptical through hole in the displacement shaft 806. When the displacement handle 904 is released, the compression spring 909 releases pressure and pushes the pressure plate 910 downward. The downward movement of the pressure plate 910 drives the displacement column 905 downward. The downward movement of the displacement column 905 drives the limiting block 906 into the cross-shaped groove of the displacement block 903. At this time, the displacement block 903 drives the nozzle 901 to be fixed in the designated position. By adjusting the position of multiple nozzles 901, the spraying range of the nozzles 901 can be precisely controlled to avoid overlapping or uneven areas, meet the ideal asphalt spraying effect, and ensure the quality and durability of the road.

[0049] After the position of nozzle 901 is adjusted by displacement mechanism 9, the angle of nozzle 901 is adjusted by adjustment mechanism 8. Twist locking handle 809 to rotate 90 degrees. The rotation of locking handle 809 to rotate locking shaft 808 to rotate 90 degrees. The rotation of locking shaft 808 to rotate unlocking block 815 to rotate 90 degrees around the center of locking shaft 808. Locking block 815 rotates 90 degrees and coincides with the square groove of the circular through hole in locking plate 810. Reset spring 816 retracts and pulls trigger block 814. The upward movement triggers the upward movement of the trigger block 814, pushing the locking shaft 808 upward. The upward movement of the locking shaft 808 causes the unlocking block 815 to pass through the circular through-hole and square groove of the locking plate 810. The tension spring 813 at the upper end of the clamping plate 811 releases its elasticity and contracts. Simultaneously, the tension spring 813 at the lower end of the clamping plate 811 stretches and, through the fixing block, causes the lower ends of the two clamping plates 811 to disengage from the adjusting shaft 803. Under the action of the rotating shaft in the middle of the clamping plate 811, the lower ends of the two clamping plates 811 move in opposite directions, causing the two... The upper ends of the clamping plates 811 move towards each other. This movement of the upper ends of the two clamping plates 811 drives the rollers 812 to move towards each other via a rotating shaft. Under the action of the inclined surface at the lower end of the trigger block 814, the rollers 812 move towards each other, pushing the trigger block 814 to slide upward within the two sliding frames 807. The upward sliding of the trigger block 814 causes the lower locking pin to disengage from the adjusting shaft 803. At this time, the adjusting handle 802 is rotated, which drives the adjusting shaft 803 to rotate. The rotation of the adjusting shaft 803 drives the adjusting... When bevel gear 804 rotates, it engages with rotating bevel gear 805. The rotation of bevel gear 804 drives rotating bevel gear 805 to rotate, which in turn drives displacement shaft 806 to rotate. The rotation of displacement shaft 806 causes displacement block 903 to deflect to one side, which in turn causes nozzle 901 to deflect to one side. This allows nozzle 901 to be quickly adjusted to a specified angle, precisely controlling the asphalt spraying area, avoiding asphalt waste, and reducing road construction costs.

[0050] After adjusting the nozzle 901 to the specified angle, press down on the locking handle 809. The downward movement of the locking handle 809 causes the locking shaft 808 to move downward. The downward movement of the locking shaft 808 causes the unlocking block 815 to pass through the circular through hole and square slide groove of the locking plate 810. The downward movement of the locking shaft 808 pushes the trigger block 814 to slide downward within the two sliding frames 807. Under the action of the inclined surface at the lower end of the trigger block 814, the downward sliding of the trigger block 814 pushes the rollers 812 on both sides to slide in the opposite direction. The reverse sliding of the rollers 812 drives the upper ends of the two clamping plates 811 to slide in the opposite direction through the rotating shaft. Under the action of the central rotating shaft of the clamping plate 811, the upper ends of the two clamping plates 811 slide in opposite directions, causing the lower ends of the two clamping plates 811 to move towards each other and contact and lock with the adjusting shaft 803. The trigger block 814 slides down to make the lower locking pin contact with the adjusting shaft 803. Twist the locking handle 809 to rotate 90 degrees. The rotation of the locking handle 809 to rotate the locking shaft 808 to rotate 90 degrees, so that the unlocking block 815 is stuck on the lower surface of the locking plate 810. At this time, the adjusting mechanism 8 is locked, preventing the nozzle 901 from deflecting during the movement of the equipment, which would cause the asphalt spraying area to become out of control.

[0051] When the ball valve 13 connecting tank 1 to the three-way pipe 20 is opened and the ball valve 13 connecting air pipe 15 to the three-way pipe 20 is closed, the drive mechanism 12 is started to drive the compression mechanism 5 to draw in air and deliver it into tank 1. The drive motor 1201 starts, and its output drives one of the drive pulleys 1202 to rotate. Under the action of the second belt 1207, the rotation of the drive pulley 1202 drives the compression pulley 1206 to rotate. The rotation of the compression pulley 1206 drives one of the compression shafts 502 to rotate, and the rotation of the compression shaft 502 drives the compression gear 505 to rotate. The compression gear 505 is meshed with the driven gear 506. The rotation of the compression gear 505 drives the driven gear 506 to rotate, which in turn drives another compression shaft 502 to rotate. The rotation of the two compression shafts 502 drives the two impellers 503 to rotate. The two impellers 503 are meshed and connected. The rotation of the two impellers 503 forces air to be drawn in from the air intake 508 and delivered to the three-way pipe 20, increasing the pressure inside the tank 1. This causes the asphalt to enter the conveying pipe 17 through the discharge pipe 16 and then be sprayed out through the nozzle 901 to spread asphalt evenly over the designated area, thus avoiding inconsistent thickness.

[0052] When the drive mechanism 12 starts and drives the mixing mechanism 11 to heat and mix the asphalt in the tank 1, the drive motor 1201 starts. The output end of the drive motor 1201 drives another drive pulley 1202 to rotate. Under the action of the first belt 1204, the drive pulley 1202 rotates and drives the mixing pulley 1205 to rotate. The mixing pulley 1205 rotates and drives the mixing shaft 1104 to rotate. The mixing shaft 1104 rotates and drives the sealing column 1101 to rotate. The sealing column 1101 rotates and drives the mixing rod 1103 to rotate around the mixing shaft 1104. The heating box 1102 drives the heating wire in the mixing rod 1103 to heat up, so that the mixing rod 1103 mixes and heats the asphalt in the tank 1, preventing the asphalt from solidifying and facilitating asphalt spraying.

[0053] The traction device drives the equipment forward, and the sweeping mechanism 6 sweeps the area where asphalt spraying is needed. The four electric telescopic booms 602 are activated, extending and causing the sweeping plate 601 to move downwards. After the two auxiliary wheels 603 contact the load-bearing wheel 701, the electric telescopic booms 602 are deactivated. As the equipment moves forward, it drives the load-bearing wheel 701 to rotate. The rotation of the load-bearing wheel 701 drives the two auxiliary wheels 603 to rotate, which in turn drives the drive pulley 604 to rotate. Under the action of the sweeping belt 605, the drive pulley 604 rotates, driving the transmission pulley 609 to rotate. The rotation of the transmission pulley 609 drives the drive shaft 608 to rotate. The rotation of the 08 drive two transmission bevel gears 610 to rotate. The transmission bevel gears 610 mesh with the sweeping bevel gears 611. The rotation of the transmission bevel gears 610 drives the sweeping bevel gears 611 to rotate. The two transmission bevel gears 610 are arranged in opposite directions so that the two sweeping bevel gears 611 rotate in opposite directions. The opposite rotation of the two sweeping bevel gears 611 drives the two sweeping shafts 612 to rotate in opposite directions. The opposite rotation of the two sweeping shafts 612 drives the two sweeping brushes 613 to rotate in opposite directions. The opposite rotation of the two sweeping brushes 613 cleans the area that needs to be sprayed with asphalt, preventing garbage and impurities from affecting the bonding effect between the asphalt surface layer and the non-asphalt base material, and ensuring the structural strength and stability of the road surface.

The locking handle 809 is pressed down to make the trigger block 814 and the clamping plate 811 hold the adjustment shaft 803. The locking handle 809 is pressed down and turned in the opposite direction by 90 degrees to lock the trigger block 814 in the specified position.
