[0016] Beneficial effects

[0017] This utility model provides a crack sealing machine for asphalt pavement repair. It has the following beneficial effects:

[0018] 1. This asphalt pavement repair crack sealing machine adjusts the position of the main dust suction hood by raising and lowering it. The inner lining, which is elastically connected to the main dust suction hood, can contact the ground, forming a relatively sealed environment at the crack location of the asphalt pavement to ensure negative pressure. The dust suction box works together to extract air from the inside of the main dust suction hood to clean particles and dust in the crack. The detachable air guide hood allows the sucked-in particles and air to enter the upper part of the air guide hood. The space formed between the outer wall of the air guide hood and the inner wall of the inner lining can be used to store the cleaned particles for convenient later centralized cleaning. The hollow rubber ring increases the deformation range of the inner lining. With the help of a spring, the inner lining is pushed down to contact the ground, so that the inner lining can fully contact the ground to ensure sealing and improve the dust suction effect.

[0019] 2. This asphalt pavement repair crack sealing machine uses the output shaft of a push rod to push the main dust suction hood down, and the main dust suction hood drives the guide rod to move down synchronously, thereby realizing the lifting and lowering of the main dust suction hood, which facilitates the adjustment of the dust suction position and height of the main dust suction hood.

[0020] 3. In this asphalt pavement repair crack sealing machine, dust and stones are sucked into the air guide hood and moved upward with the rising airflow. The airflow is sprayed out from the spray pipe and guided by the arc surface of the guide plate to be discharged to one side outside the air guide hood. The hose is installed on the side away from the guide plate. This design can prevent stones from being sucked into the hose and damaging the blower, and can also ensure the effect of concentrated collection of stones. Attached Figure Description

[0027] A crack sealing machine for asphalt pavement repair, such as Figure 1 and Figure 2 As shown, it includes:

[0028] The carrier 10 has a material storage bin 11 fixedly installed on its top. The top of the carrier 10 also has a dust collection box 12 fixedly installed on its top. The material storage bin 11 has a stirring rod inside, which is driven by a motor fixedly installed on the top of the material storage bin 11. The material storage bin 11 also has a pump inside, and the output port of the pump is fixedly connected to a retractable hose. Material is injected into the cracks in the road surface through the hose. The top of the dust collection box 12 has a fan fixedly installed on its top. The dust collection box 12 has an air inlet on one side, which is connected to the hose.

[0029] like Figure 2 , Figure 3 and Figure 4As shown, the nozzle assembly is located on one side of the carrier 10 for vacuuming dust from floor crevices. The nozzle assembly includes a main vacuum hood 20, an inner liner 21, and an air guide hood 22. The main vacuum hood 20 is movably located on one side of the carrier 10 and can be raised and lowered. The inner liner 21 is elastically connected to the main vacuum hood 20 and can be close to the ground. The air guide hood 22 is detachably installed inside the inner liner 21. The main vacuum hood 20 is connected to the air inlet of the vacuum box 12 via a hose. The main vacuum hood 20 is a rectangular box with an open bottom. The inner liner 21 is a rectangular frame and is slidably located inside the cavity of the main vacuum hood 20. A spring is fixedly installed on the top of the inner liner 21 and abuts against the inner top surface of the main vacuum hood 20. The air guide hood 22 is a rectangular funnel with its larger port facing downwards. A sealing ring 25 is fixedly installed on the outer wall of the air guide hood 22 and can abut against the inner wall of the inner liner 21 to fix the air guide hood 22.

[0030] In this solution, the position of the main dust hood 20 is adjusted by raising and lowering it, while the inner liner 21, which is elastically connected to the main dust hood 20, can touch the ground, forming a relatively sealed environment at the cracks in the asphalt pavement to ensure negative pressure. In conjunction with the dust collection box 12, air is drawn from the inside of the main dust hood 20 to clean particles and dust in the gaps. The detachable air guide hood 22 allows the sucked-in particles and air to enter above it. The space formed between the outer wall of the air guide hood 22 and the inner wall of the inner liner 21 can be used to store the cleaned particles, facilitating centralized cleaning later.

[0031] like Figure 2 and Figure 3 As shown, a guide rod 13 and a push rod 14 are provided on one side of the carrier 10. The push rod 14 is slidably connected to the carrier 10 and fixedly connected to the main dust hood 20. The output shaft of the push rod 14 is fixedly connected to the top surface of the main dust hood 20. The main dust hood 20 is pushed down by the output shaft of the push rod 14. The main dust hood 20 drives the guide rod 13 to move down synchronously, thereby realizing the lifting and lowering of the main dust hood 20, which facilitates the adjustment of the dust suction position and height of the main dust hood 20.

[0032] like Figure 4 and Figure 5 As shown, the nozzle assembly also includes a jet pipe 23 and a guide plate 24. Both the guide plate 24 and the guide plate 25 are fixedly connected to the air guide shroud 22. The guide plate 24 can guide the particles sucked in by the jet pipe 23 toward one side of the air guide shroud 22. The jet pipe 23 passes through the center of the top of the air guide shroud 22. The guide plate 24 is an arc-shaped plate. The end of the guide plate 24 is fixedly connected to the top surface of the air guide shroud 22. The concave surface of the guide plate 24 faces the port of the jet pipe 23. The guide plate 24 forms an arc-shaped barrier above the jet pipe 23.

[0033] After dust and pebbles are sucked into the air guide hood 22, they move upward with the rising airflow. The airflow is ejected from the jet pipe 23 and guided by the arc surface of the guide plate 24 to be discharged to one side outside the air guide hood 22. The hose is installed on the side away from the guide plate 24. This design can prevent pebbles from being sucked into the hose and damaging the blower, and can also ensure the effect of concentrated collection of pebbles.

[0034] like Figure 4 As shown, a rubber ring 26 is fixedly installed at the bottom of the inner liner 21. The rubber ring 26 is U-shaped and hollow inside to form a buffer cavity. The hollow rubber ring 26 increases the deformation range of the bottom of the inner liner 21. With the help of the spring, the inner liner 21 is pushed down to touch the ground, so that the bottom of the inner liner 21 can fully contact the ground to ensure sealing and improve the dust collection effect.

[0035] The working principle of this utility model is as follows: A pump is installed inside the hopper 11, and a retractable hose is fixedly connected to the output port of the pump. Material is injected into the cracks in the road surface through the hose. A fan is fixedly installed on the top of the dust collection box 12, and an air inlet is provided on one side of the dust collection box 12. The air inlet is connected to the hose. The output shaft of the push rod 14 pushes the main dust collection hood 20 to descend. The main dust collection hood 20 drives the guide rod 13 to move down synchronously, thereby realizing the lifting and lowering of the main dust collection hood 20. A hollow rubber ring 26 is set to increase the deformation range of the bottom of the inner lining 21. With the help of the spring, the inner lining 21 is pushed down to touch the ground, so that the bottom of the inner lining 21 can fully contact the ground to ensure sealing. A relatively sealed environment is formed at the cracks in the asphalt road surface to ensure negative pressure. After dust and stones are sucked into the air guide hood 22, they move upward with the rising airflow. The airflow is sprayed out from the spray pipe 23 and guided by the arc surface of the guide plate 24 to be discharged to the outside of the air guide hood 22. The hose is installed on the side away from the guide plate 24.
