Description

Technical Field

[0001] This invention relates to the field of road maintenance technology, and more specifically to an asphalt pavement flattening device. Background Technology

[0002] Asphalt pavement refers to various types of road surfaces constructed by incorporating road-grade asphalt materials into mineral aggregates. Asphalt binders enhance the ability of paving aggregates to resist damage from traffic and natural factors, resulting in a smooth, dust-free, impermeable, and durable surface. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. While the asphalt structural layer of asphalt pavement itself falls under the category of flexible pavement, its base layer can also utilize rigid cement concrete or semi-rigid hydraulic materials in addition to flexible materials. Asphalt roads are prone to damage over long-term use; therefore, rapid maintenance of asphalt pavement is crucial to ensure safe vehicle operation.

[0003] A search revealed an existing patent (publication number: CN109736159B) that discloses a highway asphalt pavement repair system and method, including a connecting frame, a main frame, an asphalt material flow device, a lifting frame, a flattening mechanism, and a fork mechanism. The asphalt material flow device in this invention is used to deliver asphalt to the location of the pavement to be repaired, and the height and angle of the flow channel are adjustable, facilitating the injection of asphalt material into the pavement to be repaired. After delivery, the flattening mechanism is switched to flatten the asphalt material. The main frame is rotatably connected to the upper end of the connecting frame, the asphalt material flow device is slidably connected to the right end of the main frame, the lifting frame is slidably connected to the upper end of the main frame, the asphalt material flow device and the lifting frame are fixedly connected, the flattening mechanism is fixedly connected to the upper end of the lifting frame, and the fork mechanism is mounted on the flattening mechanism.

[0004] In common methods for repairing small potholes in asphalt pavements, after the potholes are cut and corrected, manual repair involves filling the potholes with repair particles, which requires a large amount of manpower to spread the repair materials and then compact them. When using mechanical operations, asphalt repair liquid made by melting the machinery at high temperatures is often used to fill the potholes, which is complicated and has certain operational risks. Therefore, in order to solve the above problems, it is necessary to propose an asphalt pavement compaction device. Summary of the Invention

[0005] The main technical problem solved by this invention is to provide an asphalt pavement flattening device that can solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention proposes an asphalt pavement flattening device, including a movable frame, four self-locking universal wheels at the bottom of the movable frame, a translation mechanism fixedly installed inside the movable frame, a fixed base slidably connected to the movable frame through the translation mechanism, a feeding hopper fixedly installed on the top of the fixed base, a driving mechanism fixedly installed on the top of the feeding hopper, a mixing mechanism fixedly installed on the top of the driving mechanism, a discharge protective shell fixedly installed at the bottom of the fixed base, a baffle fixedly installed at the bottom of the discharge protective shell, a discharge hopper fixedly installed inside the discharge protective shell, a discharge mechanism fixedly installed inside the discharge hopper, and a flattening mechanism retractably installed at the bottom of the mixing mechanism.

[0007] Furthermore, the drive mechanism includes a mobile device base fixedly mounted on the top of the feed hopper, an annular slider slidably mounted inside the mobile device base, and pushers rotatably mounted on both sides of the annular slider. The translation mechanism includes four slide rods fixedly mounted inside the mobile frame, and sliding seats slidably mounted on the outer sides of the four slide rods. The fixed base is fixedly mounted between the four sliding seats via the slide rods.

[0008] Furthermore, the mixing mechanism includes a circuit box fixedly installed on the top of the mobile device base, a motor fixedly installed inside the circuit box, a mixing shaft fixedly installed at the motor output end, and a spiral extrusion strip fixedly installed on the outside of the mixing shaft, with the spiral extrusion strip located on the top of the feeding mechanism.

[0009] Furthermore, an agitator is fixedly installed on the outside of the agitator shaft and above the spiral extrusion bar, and a scraper is fixedly installed on the outside of the agitator and fits against the inner wall of the feed hopper.

[0010] Furthermore, the flattening mechanism includes a flattening base slidably disposed at the bottom of the stirring shaft, a compression spring fixedly disposed at the bottom of the stirring shaft, the bottom of the compression spring being fixedly connected to the flattening base, three connecting rods evenly disposed on the outer side of the flattening base, a pressing plate being rotatably connected to one side of each of the three connecting rods, multiple rebound mechanisms being fixedly disposed inside each of the three connecting rods, one side of each rebound mechanism being rotatably connected to the pressing plate, and an inclined surface being fixedly disposed on the top of each of the three pressing plates in the opposite direction of movement.

[0011] Furthermore, the rebound mechanism includes a rebound block fixedly installed inside the connecting rod, a rebound rod slidably installed inside the rebound block, and a retraction spring movably sleeved on the outside of the rebound rod. The two ends of the retraction spring are fixedly connected to the rebound block and the rebound rod respectively, and one side of the rebound rod is fixedly connected to the pressure plate.

[0012] Furthermore, the feeding mechanism includes two feeding blocks that are rotatably installed inside the feeding hopper. One side of each feeding block is in close contact with the stirring shaft, and a pull rod is rotatably installed on one side of each feeding block. An adjustment mechanism is slidably installed on the inner side of each pull rod.

[0013] Furthermore, the adjustment mechanism includes a connecting block that slides inside the pull rod at both ends. A threaded rod is threadedly connected to one side of the connecting block. The threaded rod is rotatably mounted on the side of the discharge hopper. An adjustment rod is drivenly connected to the bottom side of the threaded rod. Both the adjustment rod and the threaded rod are fixedly equipped with bevel gears. The adjustment rod passes through the discharge protective shell and is rotatably connected to the discharge protective shell.

[0014] Furthermore, limit seats are fixedly installed at the connection points between the two sides of the annular slider and the pusher. Both limit seats are rotatably connected to the pusher. Limit blocks are fixedly installed on both sides of the connection points between the two limit seats and the pusher. All four limit blocks limit the pusher so that the pusher can only rotate 180 degrees.

[0015] Furthermore, both feeding blocks are fixedly equipped with arc-shaped sealing plates on the connection side with the feeding hopper. The outer sides of the two arc-shaped sealing plates are in contact with the feeding hopper, and the rotation center of the two arc-shaped sealing plates is consistent with that of the feeding blocks.

[0016] The beneficial effects of the asphalt pavement leveling device of the present invention are as follows:

[0017] By setting up a translation mechanism, a feeding mechanism, and a flattening mechanism, the device is first cut into the potholes in the road. The self-locking casters with telescopic extension are used to move the device to the pothole. Then, the repair particles are poured into the feed hopper. The drive mechanism is then turned on and the feeding mechanism is opened to pour the repair particles into the pothole for filling. At the same time, the flattening mechanism rotates to flatten the repair particles. The fixed base is moved by the translation mechanism to make the repair particles fill the pothole quickly and evenly. After that, the flattening mechanism squeezes and flattens the repair particles, which improves the efficiency of asphalt pavement repair.

[0018] By setting up a flattening base, a flattening plate, and a rebound mechanism, during use, the repair particles are poured into the pits and depressions. The stirring shaft drives the flattening base to rotate, and at the same time, the flattening base drives the flattening plate to rotate. The rotating flattening plate flattens the accumulated repair particles, and the flattening efficiency is improved by the translation mechanism. Meanwhile, the particles falling on the top of the flattening plate slide down through the inclined surface of the flattening plate and fall to the bottom of the next flattening plate for flattening. When the repair particles fill the pits and depressions and overflow, the repair particles squeeze the rebound mechanism on one side of the flattening plate and the compression spring inside the flattening base. At the same time, the flattening plate squeezes the repair particles under the action of the elastic force, thus flattening the repair particles, effectively improving the flattening speed, and making the operation more convenient.

[0019] By incorporating a feeding stop, a pull rod, and an adjustment mechanism, the device operates by first pulling the pull rod in an arc motion using the adjustment mechanism. This causes the two feeding stops to move downwards in an arc motion inside the feeding bin. Repair particles then fall through the gradually widening gap between the two feeding stops and into the potholes. When the potholes are almost full, the adjustment mechanism narrows the gap between the two feeding stops, reducing the feeding rate and preventing the repair particles from overflowing. Finally, the device continues feeding or stops depending on the condition of the flattened road surface. This prevents excessive discharge of repair particles, which can lead to difficulties in cleaning and flattening, further improving the device's practicality. Attached Figure Description

[0036] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0037] like Figure 1-14As shown, the present invention provides an asphalt pavement flattening device, including a movable frame 1. Four self-locking casters are telescopically mounted on the bottom of the movable frame 1. A translation mechanism is fixedly mounted inside the movable frame 1. The movable frame 1 is slidably connected to a fixed base 2 via the translation mechanism. A feeding hopper 201 is fixedly mounted on the top of the fixed base 2. A driving mechanism is fixedly mounted on the top of the feeding hopper 201. A mixing mechanism is fixedly mounted on the top of the driving mechanism. A discharge protective shell 202 is fixedly mounted on the bottom of the fixed base 2. A baffle 203 is fixedly mounted on the bottom of the discharge protective shell 202. A discharge hopper 204 is fixedly mounted inside the discharge protective shell 202. The device is equipped with a feeding mechanism and a flattening mechanism at the bottom of the mixing mechanism. By incorporating these mechanisms, the device first cuts the potholes in the road, then moves the device to the pothole using the self-locking casters. Next, the repair particles are poured into the feed hopper 201. The drive mechanism is then activated, and the feeding mechanism is opened to fill the pothole with the repair particles. Simultaneously, the flattening mechanism rotates to flatten the repair particles. The fixed base 2 is moved by the feeding mechanism, allowing the repair particles to fill the pothole quickly and evenly. Finally, the flattening mechanism presses and flattens the repair particles, improving the efficiency of asphalt pavement repair.

[0038] In this embodiment, the driving mechanism includes a mobile device base 3 fixedly mounted on the top of the feed hopper 201. An annular slider 302 is slidably mounted inside the mobile device base 3, and pushers 301 are rotatably mounted on both sides of the annular slider 302. The translation mechanism includes four slide rods 101 fixedly mounted inside the mobile frame 1. Slide seats 102 are slidably mounted on the outer sides of the four slide rods 101. The fixed base 2 is fixedly mounted between the four slide seats 102 via the slide rods. The driving mechanism enables rapid movement of the device, and the rotation and reversal of the pushers 301 are achieved through the annular slider 302, which improves the convenience of operation and repair efficiency.

[0039] In this embodiment, the stirring mechanism includes a circuit box 4 fixedly installed on the top of the mobile device base 3. A motor 401 is fixedly installed inside the circuit box 4. A stirring shaft 402 is fixedly installed at the output end of the motor 401. A spiral extrusion strip 403 is fixedly installed on the outside of the stirring shaft 402. The spiral extrusion strip 403 is located at the top of the feeding mechanism. Through the above arrangement, the repair particles are stirred and extruded and fed at the same time, avoiding blockage and improving the feeding rate.

[0040] In this embodiment, a stirring rod 404 is fixedly installed on the outside of the stirring shaft 402 and above the spiral extrusion bar 403. A scraper is fixedly installed on the outside of the stirring rod 404 and fits against the inner wall of the feed hopper 201. With the above arrangement, the inner wall of the feed hopper 201 is scraped while stirring and feeding, so as to avoid the repair particles from sticking to the inner wall of the feed hopper 201.

[0041] In this embodiment, the flattening mechanism includes a flattening base 5 slidably disposed at the bottom of the stirring shaft 402. A compression spring 405 is fixedly disposed at the bottom of the stirring shaft 402, and the bottom of the compression spring 405 is fixedly connected to the flattening base 5. Three connecting rods 501 are evenly disposed on the outer side of the flattening base 5. A pressing plate 502 is rotatably connected to one side of each of the three connecting rods 501. Multiple rebound mechanisms are fixedly disposed inside each of the three connecting rods 501, and one side of each rebound mechanism is rotatably connected to the pressing plate 502. An inclined surface is fixedly disposed on the top of each of the three pressing plates 502, which is inclined in the opposite direction of movement. By setting the flattening base 5, the pressing plate 502, and the rebound mechanisms, during use, repairs are made easier. When the granules are poured into the pits, the stirring shaft 402 drives the flattening base 5 to rotate, and at the same time, the flattening base 5 drives the pressing plate 502 to rotate. The rotating pressing plate 502 flattens the accumulated repair granules, and the flattening efficiency is improved by the translation mechanism. Meanwhile, the granules falling on the top of the pressing plate 502 slide down through the inclined surface on the top of the pressing plate 502 and fall into the bottom of the next pressing plate 502 for flattening. When the repair granules fill the pits and overflow, the repair granules squeeze the rebound mechanism on one side of the pressing plate 502 and the compression spring 405 inside the flattening base 5. At the same time, the pressing plate 502 squeezes the repair granules under the action of elasticity, thus flattening the repair granules.

[0042] In this embodiment, the rebound mechanism includes a rebound block 503 fixedly disposed inside the connecting rod 501. A rebound rod 504 is slidably disposed inside the rebound block 503. A retraction spring 505 is movably sleeved on the outside of the rebound rod 504. The two ends of the retraction spring 505 are fixedly connected to the rebound block 503 and the rebound rod 504, respectively. One side of the rebound rod 504 is fixedly connected to the pressure plate 502. The above arrangement rebounds the pressure plate 502. The rebound block 503 and the rebound rod 504 increase the force-bearing area between the pressure plate 502 and the connecting rod 501, making the connection more stable.

[0043] In this embodiment, the feeding mechanism includes two feeding blocks 7 rotatably disposed inside the feeding bin 204. One side of each feeding block 7 is tightly fitted with the stirring shaft 402. A pull rod 701 is rotatably disposed on one side of each feeding block 7, and an adjustment mechanism is slidably disposed on the inner side of each pull rod 701. By setting the feeding blocks 7, pull rods 701, and adjustment mechanisms, in use, the adjustment mechanism first pulls the pull rods 701 in an arc motion, which drives the two feeding blocks 7 to move downward in an arc motion inside the feeding bin 204. At this time, the repair particles fall through the gradually widening gap between the two feeding blocks 7 and are poured into the pothole. When the pothole is about to be filled with repair particles, the adjustment mechanism reduces the gap between the two feeding blocks 7, thereby reducing the feeding rate and preventing the repair particles from overflowing into the pothole. Finally, the feeding is continued or stopped according to the condition of the road surface after flattening, thus avoiding the situation where too many repair particles are poured out, making it difficult to clean and flatten.

[0044] In this embodiment, the adjustment mechanism includes a connecting block 603 with both ends slidably disposed inside the pull rod 701. A threaded rod 602 is threadedly connected to one side of the connecting block 603. The threaded rod 602 is rotatably disposed on one side of the feeding bin 204. An adjustment rod 6 is drivenly connected to the bottom side of the threaded rod 602. Both the adjustment rod 6 and the threaded rod 602 are fixedly provided with bevel gears 601. The adjustment rod 6 passes through the feeding protective shell 202 and is rotatably connected to the feeding protective shell 202. The feeding mechanism is adjusted through the above arrangement, making the adjustment operation more convenient. At the same time, the force on the thread on the threaded rod 602 makes the feeding stop 7 more stable when under force.

[0045] In this embodiment, limit seats 304 are fixedly provided at the connection points between the annular slider 302 and the pusher 301 on both sides. Both limit seats 304 are rotatably connected to the pusher 301. Limit blocks 303 are fixedly provided on both sides of the connection points between the two limit seats 304 and the pusher 301. All four limit blocks 303 limit the pusher 301 so that the pusher 301 can only rotate 180 degrees. During operation, the pusher 301 is rotated by the limit seats 304 and limited by the limit blocks 303, so that the operator can operate from multiple angles and positions, which improves the practicality of the device.

[0046] In this embodiment, two arc-shaped sealing plates 702 are fixedly installed on the connecting sides of the two feeding blocks 7 and the feeding bin 204. The outer sides of the two arc-shaped sealing plates 702 are in contact with the feeding bin 204, and the rotation center of the two arc-shaped sealing plates 702 is consistent with that of the feeding blocks 7. During feeding, the arc-shaped sealing plates 702 are used to seal the gap between the feeding blocks 7 and the feeding bin 204 to prevent particles from entering the gap and affecting the use. At the same time, the contact area between the feeding blocks 7 and the feeding bin 204 is increased, which improves the stability during use.

[0047] The working principle of this device is:

[0048] In use, first cut the potholes in the road, then move the device to the pothole using the telescopic self-locking casters, and then pour the repair particles into the feed hopper 201. Next, turn on the drive mechanism and open the feeding mechanism to pour the repair particles into the pothole for filling. At the same time, the flattening mechanism rotates to flatten the repair particles, and the fixed base 2 is moved by the translation mechanism to make the repair particles fill the pothole quickly and evenly. When the repair particles reach a certain amount, the flattening mechanism squeezes and flattens them.

[0049] All electrical components mentioned in this article are real-world electrical components.

Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention are also within the protection scope of the present invention.
