Description

Technical Field

[0001] This invention belongs to the field of road construction technology and relates to a device and process for preparing a functional layer for preventive maintenance of asphalt pavement. Background Technology

[0002] Fine surface treatment technology for asphalt pavement, also known as fine surface treatment, involves applying an epoxy-modified asphalt pavement curing agent to the old asphalt pavement using specialized equipment, assuming the pavement already has good traffic quality. This material penetrates and absorbs into the pavement, closing micro-cracks. Combined with specially formulated fine sand, and after a series of physicochemical reactions, it forms an ultra-thin, wear-resistant, and anti-skid protective layer on the asphalt pavement. Fine surface treatment offers stronger adhesion, a more stable structure, and better wear and anti-skid performance. It is also not limited by elevation or weight and can be used multiple times.

[0003] A search revealed that application CN 114319020 B discloses an emulsified asphalt spraying device and a paving method using the device. The device includes a vehicle body with a tank, an output structure, and a spraying structure mounted on it. The tank is divided into an upper and lower layer along its length by a partition. A connecting hole is provided at one end of the partition near the tank, connecting the upper and lower layers. The output structure includes a first dual pump and a temporary storage structure. The inlet of the first dual pump is connected to the lower layer away from the connecting hole via a pipe. The first outlet of the first dual pump is connected to the upper layer away from the connecting hole via a pipe. The second outlet of the first dual pump is connected to the temporary storage structure via a pipe, and a valve is connected in series at the second outlet of the first dual pump. This application enables the asphalt spraying vehicle to stably store emulsified asphalt.

[0004] The equipment also has the following disadvantages: It stores and mixes materials in a tank, requiring additional tank trucks to transport the materials during use. If materials cannot be transported in a timely manner, construction will be halted. Furthermore, the transport process is time-limited; if the time is too long, the material will solidify, making it inconvenient to use. Adding and mixing materials directly on the truck body, followed by direct use, is a more convenient method. Therefore, we propose a device and process for preparing a fine-surface treatment functional layer for preventive maintenance of asphalt pavements to solve the aforementioned problems. Summary of the Invention

[0005] In view of this, in order to solve the problems of the need for additional tank trucks to transport materials during use, which leads to construction downtime if materials cannot be transported in time, and the inconvenience of use due to time constraints during transportation if the material solidifies over a long period of time.

Then the vehicle body 1 moves to drive the conveyor roller 29 to rotate, and the electromagnetic clutch 42 is activated to drive the rotating plate 49 to rotate, which can drive the two inner cylinders 10 to move in opposite directions, so that one set of first discharge holes 16 and second discharge holes 17 correspond to each other, and the other set of first discharge holes 16 and second discharge holes 17 are staggered.

[0072] S3. Start motor 5 drives storage box 3 to move on limit rod 13. Material flows into discharge box 4 through first discharge hole 16 and second discharge hole 17. When conveying roller 29 rotates, it drives material to flow to both sides of discharge box 4 and spreads it on the road surface through discharge port at the bottom of discharge box 4.

[0073] S4. Secondly, the other inner cylinder 10 rotates to feed the material while being stirred by the limiting rod 13, so that it can be recycled.

[0074] Working principle: When in use, the electric push rod 28 is started to drive the discharge box 4 to move downward, so that the roller 32 contacts the ground and puts the material into the first storage space 7 and the second storage space 8 respectively. Then, the motor 5 is started to drive the first screw 11 to rotate. The rotation of the first screw 11 can drive the limit plate 19 to rotate. The limit plate 19 drives the extension cylinder 18 to rotate through the third retaining ring 24. The rotation of the extension cylinder 18 can drive the limit plate 19 to rotate. The material can be stirred through the limit rod 13. When the first feed hole 14 and the second feed hole 15 correspond to the through hole 9, the material will enter the inner cylinder 10, so that it is fed while being stirred.

[0075] After mixing, the vehicle moves, causing roller 32 to roll on the road surface, which in turn causes conveyor roller 29 to rotate. This activates electromagnetic clutch 42. At this time, conveyor roller 29 can drive the output end of electromagnetic clutch 42 to rotate via spline shaft 31 and fourth fixed plate 41, causing reciprocating screw 45 to rotate. The rotation of reciprocating screw 45 causes sleeve rod 39 to move up and down on third fixed plate 40. When sleeve rod 39 moves upward, it can drive second rotating ring 38 to rotate. Second rotating ring 38, through oblong hole 46 and extension rod 36, can drive first rotating ring 26 to move, thereby driving one of them... The inner cylinder 10 moves outward, causing the first discharge hole 16 to coincide with the second discharge hole 17. At the same time, the fourth retaining ring 25 engages with the second retaining ring 22. At this time, the starting motor 5 drives the first screw 11 to rotate. The rotation of the first screw 11 can drive the sliding plate 12 to slide on the limiting rod 13, thus squeezing the material inside the inner cylinder 10. The material falls into the discharge box 4 through the first discharge hole 16 and the second discharge hole 17. During the movement of the vehicle body 1, the conveying roller 29 is driven to rotate. The conveying roller 29 can transport the material to both sides of the discharge box 4, and then it falls to the ground through the discharge port at the bottom of the discharge box 4.

[0076] While the rotating plate 49 rotates, it can drive another inner cylinder 10 to move inward, so that the first retaining ring 20 and the third retaining ring 24 are engaged, and then the feeding and stirring action is performed. After the material in the inner cylinder 10 is used up, the electromagnetic clutch 42 can be activated to drive the inner cylinder 10 to move inward, and drive the other inner cylinder 10 to move outward, so as to carry out the cycle.

[0077] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 5, the electric push rod 28 and the electromagnetic clutch 42 are commonplace and are all 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.
