Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, specifically to a hot recycling maintenance vehicle for asphalt pavement. Background Technology

[0002] With the continuous advancement of transportation infrastructure construction, the mileage of asphalt pavement is constantly increasing. However, asphalt pavement that has been used for a long time will develop various defects, such as cracks, potholes, and ruts, requiring maintenance and repair. Asphalt pavement old material hot recycling maintenance vehicle has emerged to meet this need. It can efficiently utilize old asphalt pavement materials and achieve on-site hot recycling, which has significant advantages in saving resources, reducing costs, and protecting the environment.

[0003] When traditional equipment is in use, when the old material enters the mixing tank, the large temperature difference between the old material and the tank may cause the old material to come into contact with the low-temperature tank and cool down rapidly, resulting in increased viscosity and poor flow of the old material in the tank, thus affecting the fullness of subsequent mixing.

[0004] In view of this, we have studied and improved upon the existing problems to provide a hot recycling maintenance vehicle for asphalt pavement. The vehicle has a reasonable structural design, high stability, and is suitable for various applications. The aim is to solve the problems and improve the practical value through this technology. Utility Model Content

[0005] This invention heats the old asphalt pavement material while simultaneously opening a valve to heat the mixing tank. The mixing tank is preheated before the old material enters, reducing the temperature difference between the old material and the tank. This prevents the old material from rapidly cooling due to contact with the low-temperature tank, which would increase its viscosity. After the old material enters the mixing tank, heating softens the new asphalt material, reducing its viscosity and allowing for more uniform mixing of the old material with the newly added asphalt, recycling agents, and new aggregates. This invention achieves a thermal recycling maintenance vehicle for old asphalt pavement materials.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an asphalt pavement hot recycling maintenance vehicle, comprising a base plate, an air storage tank connected to the upper end of the base plate, a spray gun provided on one side of the air storage tank, a connecting pipe connected to one side of the air storage tank, a rotatable crushing blade at the lower end of the base plate, cylinders provided on both sides of the air storage tank, a pulley A provided at one end of the crushing blade, a pulley B connected to one side of pulley A, a drive shaft connected to one end of pulley B, a conveyor belt connected to the outside of the drive shaft, a connecting rod connected to one end of the drive shaft, a spring rod connected to the outside of the connecting pipe, a pulley C connected to one side of the base plate, a pulley D provided on one side of pulley C, a rotating rod connected to one end of pulley D, a material storage bin provided at the upper end of the base plate, and a mixing tank fixedly connected inside the base plate.

[0007] Preferably, the gas storage tank is fixedly connected to the upper end of the base plate, a spray gun is fixedly connected to one side of the gas storage tank, the spray gun is embedded in the lower end of the base plate, the connecting pipe is fixedly connected to one side of the gas storage tank, and the other end of the connecting pipe is connected to the mixing tank.

[0008] Preferably, the two ends of the crusher are movably connected to two sets of connecting blocks, the output end of the cylinder is connected to a push rod, the push rod extends through the bottom plate to the lower end and is fixedly connected to the connecting block, one end of the crusher is fixedly connected to a motor, the other end of the crusher is fixedly connected to a pulley A, a belt is sleeved inside the pulley A, and the other end of the belt is sleeved to a pulley B.

[0009] Preferably, one end of the pulley B is fixedly connected to a drive shaft, a conveyor belt is sleeved on the outside of the drive shaft, and a rotating rod is sleeved on the other end of the conveyor belt.

[0010] Preferably, one end of the rotating rod is fixedly connected to a connecting rod, the outer end of the connecting rod is fixedly connected to a connecting plate A, the spring rod is located at the lower end of the connecting rod, the spring rod extends through the connecting pipe to the inside and connects to the valve, and the upper end of the spring rod is fixedly connected to a connecting plate B.

[0011] Preferably, a burner is fixedly connected to one end of the connecting pipe, the pulley C is fixedly connected to the rotating rod, a belt is sleeved inside the pulley C, the pulley C is connected to the pulley D through the belt, and a rotating rod is fixedly connected to one end of the pulley D.

[0012] Preferably, a storage bin is fixedly connected to the upper end of the base plate, a conveying pipe is fixedly connected to one side of the storage bin, the storage bin is connected to the mixing tank through the conveying pipe, the rotating rod extends through the conveying pipe into the interior, and an auger plate is fixedly connected to the rotating rod on the outside of the conveying pipe.

[0013] This invention has the following beneficial effects: When the rotating rod rotates, it synchronously drives the connecting rod to rotate. When the connecting rod rotates, it synchronously drives the connecting plate A to rotate. When the connecting plate A rotates, it comes into contact with the connecting plate B, causing the connecting plate A to squeeze and flip the connecting plate B. When the connecting plate B flips, it synchronously opens the valve inside the connecting pipe, allowing the combustible gas to be burned by the burner and heat the inside of the mixing tank. This preheats the mixing tank before the old material enters it. When the old material enters, it reduces the temperature difference between the old material and the tank body, preventing the old material from rapidly deteriorating due to contact with the low-temperature tank body. Rapid cooling leads to increased viscosity. After the old material enters the mixing tank, heating softens the new asphalt material, reducing its viscosity and allowing the old material to mix more evenly with the newly added asphalt, recycling agent, and new aggregates. At the same time, heating accelerates the chemical reaction between the recycling agent and the old asphalt, effectively restoring the performance of the old asphalt and improving the quality of the recycled mixture. When the equipment stops operating, if connecting plate A does not press against connecting plate B, connecting plate B will reset via a spring rod. This reset of the spring rod will also close the valve inside the connecting pipe, thus preventing flammable gas leakage.

[0014] Its storage silo contains a certain proportion of asphalt, recycling agent, etc. When the rotating rod rotates, it will drive the auger blades to rotate synchronously. Thus, when the old material is collected and enters the mixing tank, a certain amount of new material is added to the mixing tank at the same time. This increases the accuracy of the ratio between new and old materials, while also reducing the physical exertion of the workers. In addition, the old material is processed while the equipment is running, reducing cumbersome steps. Attached Figure Description

The spray gun 3 is embedded in the lower end of the base plate 1. The connecting pipe 4 is fixedly connected to one side of the gas storage tank 2, and the other end of the connecting pipe 4 is connected to the mixing tank 23. The gas storage tank 2 stores combustible gas. Before using the equipment, the combustible gas inside the gas storage tank 2 is burned by the spray gun 3 to heat the old road material.

[0025] In an optional embodiment: two sets of connecting blocks 6 are movably connected to both ends of the crusher blade 5. A push rod 7 is connected to the output end of the cylinder 8. The push rod 7 extends through the base plate 1 to the lower end and is fixedly connected to the connecting blocks 6. A motor 9 is fixedly connected to one end of the crusher blade 5, and a pulley A10 is fixedly connected to the other end of the crusher blade 5. A belt 11 is sleeved inside the pulley A10, and a pulley B12 is sleeved at the other end of the belt 11. After the old road material is heated, the push rod 7 is pushed down by the cylinder 8. When the push rod 7 descends, it will drive the two sets of connecting blocks 6 to descend simultaneously. When the connecting blocks 6 descend, it will drive the crusher blade 5 to descend simultaneously. When the crusher blade 5 descends, it will rotate under the drive of the motor 9, thereby crushing the old road material. At the same time, when the crusher blade 5 is driven to rotate by the motor 9, it will drive the pulley A10 to rotate synchronously. When the pulley A10 rotates, it will drive the pulley B12 to rotate synchronously through the belt 11.

[0026] In an optional embodiment: a drive shaft 13 is fixedly connected to one end of pulley B12, a conveyor belt 14 is sleeved on the outside of the drive shaft 13, and a rotating rod is sleeved on the other end of the conveyor belt 14. When pulley B12 rotates, it will synchronously drive the drive shaft 13 to rotate, thereby driving the conveyor belt 14 to rotate. When the conveyor belt 14 rotates, it will transport the crushed road surface material at the front end into the mixing tank 23. When the conveyor belt 14 rotates, it will synchronously drive the rotating rod to rotate.

[0027] In an optional embodiment: a connecting rod 15 is fixedly connected to one end of the rotating rod, and a connecting plate A is fixedly connected to the outer end of the connecting rod 15. A spring rod 16 is located at the lower end of the connecting rod 15, extending through the connecting pipe 4 and connecting to the valve inside. A connecting plate B is fixedly connected to the upper end of the spring rod 16. When the rotating rod rotates, it synchronously drives the connecting rod 15 to rotate. When the connecting rod 15 rotates, it synchronously drives the connecting plate A to rotate. When the connecting plate A rotates, it contacts the connecting plate B, causing the connecting plate A to squeeze and flip the connecting plate B. When the connecting plate B flips, it synchronously opens the valve inside the connecting pipe 4, allowing the combustible gas to be burned by the burner 17 and heat the inside of the mixing tank 23. Before the old material enters the mixing tank... The mixing tank 23 is preheated. When the old material enters, it reduces the temperature difference between the old material and the tank, preventing the old material from cooling rapidly due to contact with the low-temperature tank, which would increase its viscosity. After the old material enters the mixing tank 23, it is heated to soften the new asphalt material and reduce its viscosity, allowing the old material to mix more evenly with the newly added asphalt, recycling agent, and new aggregate. At the same time, heating can accelerate the chemical reaction between the recycling agent and the old asphalt, effectively restoring the performance of the old asphalt and improving the quality of the recycled mixture. When the equipment stops operating, if the connecting plate A does not press the connecting plate B, the connecting plate B will be reset by the spring rod 16. At the same time as the spring rod 16 resets, the valve inside the connecting pipe 4 will also be closed, thus preventing the leakage of flammable gas.

[0028] In an optional embodiment: a burner 17 is fixedly connected to one end of the connecting pipe 4, a pulley C18 is fixedly connected to a rotating rod, a belt 11 is sleeved inside the pulley C18, the pulley C18 is connected to the pulley D19 through the belt 11, a rotating rod 20 is fixedly connected to one end of the pulley D19, when the rotating rod rotates, it will synchronously drive the pulley C18 to rotate, when the pulley C18 rotates, it will synchronously drive the pulley D19 to rotate through the belt 11, and when the pulley D19 rotates, it will drive the rotating rod 20 to rotate.

[0029] In an optional embodiment: a storage bin 21 is fixedly connected to the upper end of the base plate 1, and a conveying pipe 22 is fixedly connected to one side of the storage bin 21. The storage bin 21 is connected to the mixing tank 23 through the conveying pipe 22. A rotating rod 20 extends through the conveying pipe 22 and into the interior. An auger plate is fixedly connected to the rotating rod 20 inside the conveying pipe 22. The storage bin 21 stores a certain proportion of asphalt, recycling agent, etc. When the rotating rod 20 rotates, it will drive the auger plate to rotate synchronously. Thus, when the old material is collected and enters the mixing tank 23, a certain amount of new material is added to the mixing tank 23 at the same time. This increases the accuracy of the ratio between new material and old material, reduces the physical exertion of the workers, and processes the old material during equipment operation, reducing cumbersome steps.

[0030] Working principle and process: Before using the equipment, the combustible gas inside the gas storage tank 2 is burned by the spray gun 3 to heat the old road material. After the old road material is heated, the cylinder 8 pushes the push rod 7 down, which in turn drives the two sets of connecting blocks 6 to descend. When the connecting blocks 6 descend, they drive the crushing blade 5 down. When the crushing blade 5 descends, it is driven by the motor 9 to rotate, thereby crushing the old road material. At the same time, when the crushing blade 5 is driven by the motor 9 to rotate, it drives the pulley A10 to rotate synchronously. When the pulley A10 rotates, it drives the pulley B12 to rotate synchronously through the belt 11.

[0031] When pulley B12 rotates, it synchronously drives drive shaft 13 to rotate, thereby driving conveyor belt 14 to rotate. When conveyor belt 14 rotates, it transports the crushed road material from the front end into the mixing tank 23. When conveyor belt 14 rotates, it synchronously drives rotating rod to rotate. When rotating rod rotates, it synchronously drives connecting rod 15 to rotate. When connecting rod 15 rotates, it synchronously drives connecting plate A to rotate. When connecting plate A rotates, it comes into contact with connecting plate B, causing connecting plate A to squeeze connecting plate B and flip. When connecting plate B flips, it synchronously opens the valve inside connecting pipe 4, allowing combustible gas to be burned by burner 17 to heat the inside of mixing tank 23. When the equipment stops operating, when connecting plate A has not squeezed connecting plate B, connecting plate B will be reset by spring rod 16. When spring rod 16 resets, it will also close the valve inside connecting pipe 4.

[0032] When the rotating rod rotates, it will synchronously drive the pulley C18 to rotate. When the pulley C18 rotates, it will synchronously drive the pulley D19 to rotate via the belt 11. When the pulley D19 rotates, it will drive the rotating rod 20 to rotate. When the rotating rod 20 rotates, it will drive the auger plate to rotate synchronously, so that when the old material is collected and enters the mixing tank 23, a certain amount of new material is added to the mixing tank 23 at the same time.
