Description

Technical Field

[0001] This invention belongs to the field of road engineering technology, and specifically relates to an asphalt concrete continuous paving device. Background Technology

[0002] Asphalt concrete paving equipment is used to spread asphalt concrete on the road surface during road construction. It ensures that the asphalt concrete is evenly distributed on the road surface and reaches the designed thickness, guaranteeing construction efficiency and quality. However, in order to avoid downtime due to lack of materials and to ensure continuous and uniform paving, sufficient material conveying vehicles are required for material delivery. However, when material conveying vehicles are replaced, in order to prevent damage to the already paved asphalt, the material must be added away from the paved road, which can easily cause some asphalt to be missing. This requires manual replenishment, which is time-consuming and labor-intensive, and to some extent reduces the efficiency of asphalt paving. Summary of the Invention

[0003] The purpose of this invention is to provide a continuous asphalt concrete paving device to solve the above-mentioned problems. The receiving structure can disconnect the connection with the conveying pipe through the control structure. When paving is carried out and there is sufficient asphalt, the conveying pipe is blocked by the baffle to facilitate the control of asphalt and timely replenishment. When there is less asphalt on the connecting plate, the connecting plate pushes the opening on the baffle to form a connection with the conveying pipe, and the asphalt is put into the inside of the bucket for replenishment.

[0004] The present invention achieves the above-mentioned objectives through the following technical solution: an asphalt concrete continuous paving device, including a vehicle body, a material conveying vehicle, a baffle, a transmission structure, a control structure, and a bidirectional auger. The top side of the vehicle body is provided with a storage structure, and the bottom side of the vehicle body is rotatably provided with wheels. An electric telescopic rod is fixedly provided in a lateral position on the bottom side of the vehicle body. An extrusion plate is fixedly provided at the lower end of the inner rod of the electric telescopic rod. A bucket is fixedly provided on one side of the extrusion plate. A connecting structure is provided between the bucket and the vehicle body.

[0005] A material conveying pipe is vertically fixed inside the bucket. The material conveying pipe and the receiving structure are connected to each other through a control structure. A connecting plate is rotatably installed inside the bucket. A connecting rod is rotatably installed between the connecting plate and the baffle. An opening is provided inside the baffle away from the material conveying pipe. The bidirectional auger and the wheel are connected to each other through a transmission structure. A reset structure is provided between the connecting plate and the bucket. A snap-fit ​​structure is provided between the vehicle body and the material conveying vehicle.

[0006] Furthermore, the transmission structure includes a first rotating rod and a second rotating rod. The first rotating rod is fixedly mounted on the front side of the wheel axle, and the second rotating rod is fixedly mounted on the front side of the bidirectional auger axle. A squeezing roller is rotatably mounted on the front side of the bucket. Furthermore, the first rotating rod is fixedly provided with a first pulley, the second rotating rod is fixedly provided with a second pulley, the extrusion roller abuts against the belt on the second pulley, and a limit plate is provided on the first rotating rod near the first pulley for rotation.

[0007] Furthermore, the first pulley and the second pulley are connected to each other by a belt.

[0008] Furthermore, the bidirectional auger is rotatably mounted inside the bucket.

[0009] Furthermore, the storage structure includes a placement box, the interior of which has a discharge port extending laterally. The control structure includes a feeding port and a sliding plate, the feeding port being fixedly disposed inside the sliding plate and at one end of the feeding pipe.

[0010] Furthermore, a chute is provided inside the placement box near the feed inlet, and the sliding plate is slidably disposed inside the chute.

[0011] Furthermore, the connection structure includes a support plate and a connecting block. The support plate is fixedly disposed on one side of the vehicle body, and the connecting block is fixedly disposed on one side of the bucket. The connecting block is slidably disposed on one side of the support plate.

[0012] Furthermore, the reset structure includes a connecting telescopic rod, a first rotating shaft, and a second rotating shaft. The first rotating shaft is fixedly mounted on the body of the connecting plate, and the second rotating shaft is fixedly mounted on the inner wall of the bucket. The connecting telescopic rod is rotatably mounted between the first rotating shaft and the second rotating shaft, and a reset spring is fixedly connected inside the connecting telescopic rod.

[0013] Furthermore, a flattening roller is provided on one side of the vehicle body, and the baffle is slidably disposed inside the conveying pipe.

[0014] In summary, 1. The bucket facilitates the spreading of excess asphalt, and when there is insufficient asphalt during the spreading process, the connecting plate pushes the opening on the baffle to connect with the conveying pipe, allowing asphalt to be added into the bucket for replenishment, which improves work efficiency to a certain extent.

[0015] 2. When paving is not being carried out, the receiving structure disconnects the connection with the conveying pipe through the control structure. When paving is being carried out and there is sufficient asphalt, the conveying pipe is blocked by the baffle until there is a lack of asphalt. Then, the connecting plate drives the opening on the baffle to connect with the conveying pipe to replenish the asphalt, which facilitates the control of asphalt and timely replenishment.

[0016] 3. The electric telescopic rod drives the extrusion plate to be flush with the wheel, which facilitates the auxiliary bucket to spread and extrude asphalt, further improving work efficiency. At the same time, when the wheel is in motion, the connecting structure drives the bidirectional auger to rotate, which reduces the cost of use to a certain extent.

[0017] 4. The material conveyor is connected to the vehicle body through a snap-fit ​​structure, which allows for continuous replacement of the material conveyor during the asphalt paving process, thus enabling continuous asphalt paving without stopping the machine. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] See Figures 1-8As shown, an asphalt concrete continuous paving device includes a vehicle body 1, a material conveying vehicle 17, a baffle 12, a transmission structure 2, a control structure 8, and a bidirectional auger 6. The bidirectional auger 6 is composed of two augers operating in opposite directions, and is formed by several rotating spiral blades. It propels the material through rotation and can be used to transport various materials. In asphalt construction, the auger can be used to transport excess asphalt to the required location, facilitating the paving of excess asphalt. The top side of the vehicle body 1 is provided with a storage structure 3, which facilitates the pre-positioning of asphalt for replenishment. Structure 3 can use thermal insulation materials, such as rock wool, to allow for long-term placement of asphalt. Wheels 19 are rotatably mounted on the underside of the vehicle body 1 for easy movement. An electric telescopic rod 20 is fixedly mounted laterally on the underside of the vehicle body 1. An extrusion plate 15 is fixedly mounted at the lower end of the inner rod of the electric telescopic rod 20. The electric telescopic rod 20 allows workers to easily control the raising and lowering of the equipment, and the extrusion plate 15 assists in spreading the asphalt. A bucket 5 is fixedly mounted on one side of the extrusion plate 15 to easily push excess asphalt. A bidirectional auger 6 is rotatably mounted inside the bucket 5. The bucket 5, equipped with a bidirectional auger 6, facilitates the transport of excess asphalt from its interior to both sides for auxiliary paving. A connecting structure 4 connects the bucket 5 and the vehicle body 1. An electric telescopic rod 20 moves the bucket 5 on the extrusion plate 15 downwards, pushing the asphalt through the bucket 5. Simultaneously, the downward movement of the bucket 5 drives the control structure 8 downwards via the material conveying pipe 7, connecting the material inlet 801 on the control structure 8 with the outlet 302 on the receiving structure 3. The material conveying pipe 7 is vertically fixed inside the bucket 5, facilitating the delivery of additional asphalt. Furthermore, the material conveying pipe 7 contains a refueling system. The heating device ensures that the temperature of the transported asphalt is suitable, preventing asphalt from adhering to the inside of the pipe and causing blockage. The conveying pipe 7 and the receiving structure 3 are connected to each other through the control structure 8. When some asphalt moves to the connecting plate 10 on the bucket 5, it is squeezed, thereby pushing the connecting plate 10 to move. Then, the connecting plate 10 drives the baffle 12 to block the conveying pipe 7 through the connecting rod 11. The entire device adopts a high-temperature compaction process, and at the same time, it is equipped with sufficient transport vehicles and strictly controls the paving speed to avoid the phenomenon of stopping to wait for materials. The paver can carry out continuous and uniform paving, which can ensure the smoothness of the road surface and enhance the construction effect of asphalt mixture.

[0023] Furthermore, the transmission structure 2 includes a first rotating rod 201 and a second rotating rod 202. The first rotating rod 201 is fixedly mounted on the front side of the axle of the wheel 19, and the second rotating rod 202 is fixedly mounted on the front side of the axle of the bidirectional auger 6. A compression roller 14 is rotatably mounted on the front side of the bucket 5 to facilitate compression of the belt, ensuring that the belt is always connected to the second pulley 204. A first pulley 203 is fixedly mounted on the shaft of the first rotating rod 201, and a second pulley 204 is fixedly mounted on the shaft of the second rotating rod 202. The second pulley 204 has a belt abutting against the extrusion roller 14. A limiting plate 205 is rotatably mounted on the shaft of the first rotating rod 201 near the first pulley 203. Two limiting plates 205 clamp the first pulley 203 in the middle, facilitating belt restriction and preventing the belt from slipping off the first pulley 203 during rotation. The second pulleys 204 are connected to each other via belts. When the bucket 5 moves downward, it drives the second pulley 204 on the transmission structure 2 to move downward, so that the belts on the first pulley 203 and the second pulley 204 are in a taut state. Then, the vehicle body 1 moves so that the wheels 19 are driven by the belts on the first pulley 203 and the second pulley 204. Then, the second pulley 204 drives the bidirectional auger 6 to rotate through the second rotating rod 202, thereby driving the excess asphalt to be spread to both sides of the bucket 5. When the bucket 5 moves upward, the belts on the first pulley 203 and the second pulley 204 are in a loose state, so that the wheels 19 do not drive the bidirectional auger 6 when moving. In addition, two limiting plates 205 are provided on the side of the first rotating rod 201 near the first pulley 203 to limit the belt. At the same time, a squeezing roller 14 is rotatably provided on the bucket 5 near the second pulley 204. Through the limiting plates 205 and the squeezing roller 14, the belt can be easily limited and the belt can be controlled to drive.

[0024] A connecting plate 10 is rotatably mounted inside the bucket 5. The connecting plate 10 is C-shaped to facilitate the pushing of asphalt. A connecting rod 11 is rotatably mounted between the connecting plate 10 and the baffle 12. An opening 13 is provided inside the baffle 12 away from the conveying pipe 7 to facilitate the discharge of asphalt from the conveying pipe 7 through the opening 13. The bidirectional auger 6 and the wheel 19 are connected to each other through a transmission structure 2. When the wheel 19 on the vehicle body 1 moves, the bidirectional auger 6 is driven to rotate through the transmission structure 2, which facilitates the spreading of asphalt on the bucket 5. A reset structure 9 is provided between the connecting plate 10 and the bucket 5. The reset structure 9 facilitates the resetting of the connecting plate 10, making the contact surface between the connecting plate 10 and the asphalt of the bucket 5 flush. At the same time, the connecting plate 10 pushes the opening 13 on the baffle 12 and the conveying pipe... 7. A snap-fit ​​structure 16 is provided between the vehicle body 1 and the material conveying vehicle 17. The snap-fit ​​structure 16 facilitates quick and easy connection of the material conveying vehicle 17, thereby strictly controlling the paving speed and avoiding the phenomenon of stopping for material. It facilitates continuous and uniform paving of asphalt by the paving device, ensuring the smoothness of the road surface. A flattening roller 18 is provided on one side of the vehicle body 1. The flattening roller 18 facilitates the compaction of the paved asphalt, improving work efficiency. The baffle 12 is slidably set inside the material conveying pipe 7. The bucket 5 facilitates the pushing of excess asphalt. When there is insufficient asphalt during the paving process, the connecting plate 10 is reset by the reset structure 9. The connecting plate 10 pushes the opening 13 on the baffle 12 to connect with the material conveying pipe 7, and puts asphalt into the inside of the bucket 5 for replenishment.

[0025] Further, the storage structure 3 includes a placement box 301, with a discharge port 302 extending horizontally through its interior. The control structure 8 includes a feeding port 801 and a sliding plate 802. The feeding port 801 is fixedly disposed inside the sliding plate 802 and at one end of the feeding pipe 7. A groove 303 is formed inside the placement box 301 near the feeding port 801, and the sliding plate 802 is slidably disposed inside the groove 303. The connecting structure 4 includes a support plate 401 and a connecting block 402. The support plate 401 is fixedly disposed on one side of the vehicle body 1. The connecting block 402 is fixedly installed on one side of the bucket 5. When the bucket 5 moves downward, the conveying pipe 7 on the bucket 5 drives the control structure 8 to move downward, so that the conveying port 801 on the control structure 8 is connected to the discharge port 302 on the receiving structure 3, allowing asphalt to enter the interior of the bucket 5 through the conveying pipe 7. When some asphalt moves to the connecting plate 10 on the bucket 5 and is squeezed, it pushes the connecting plate 10 to move. Then, the connecting plate 10 drives the baffle 12 to block the conveying pipe 7 through the connecting rod 11. When the use is over, the bucket 5 moves upward, and then the sliding plate on the control structure 8 is driven by the conveying pipe 7. The slide plate 802 slides along the groove 303 on the storage structure 3, thereby blocking the discharge port 302 on the storage structure 3, facilitating the next operation. The connecting block 402 is slidably disposed on one side of the support plate 401. The reset structure 9 includes a connecting telescopic rod 901, a first rotating shaft 903, and a second rotating shaft 904. The first rotating shaft 903 is fixedly disposed on the body of the connecting plate 10, and the second rotating shaft 904 is fixedly disposed on the inner wall of the bucket 5. The connecting telescopic rod 901 is rotatably disposed between the first rotating shaft 903 and the second rotating shaft 904. A reset mechanism is fixedly connected inside the connecting telescopic rod 901. Spring 902, through the return spring 902, facilitates the pulling and resetting of connecting plate 10. This allows connecting plate 10 to push the opening 13 on baffle 12 to connect with conveying pipe 7. When the amount of asphalt on bucket 5 decreases, connecting plate 10, due to the lack of asphalt compression, moves to its reset position via connecting telescopic rod 901 and return spring 902 on reset structure 9. Then, connecting plate 10 pushes the opening 13 on baffle 12 into the conveying pipe 7, facilitating the replenishment of asphalt from receiving structure 3 by opening conveying pipe 7 onto connecting plate 10, thus improving work efficiency.

[0026] Using the above structure, when using this device, firstly, the vehicle body 1 and the conveying vehicle 17 are connected by the snap-fit ​​structure 16. When the conveying vehicle 17 feeds material, the electric telescopic rod 20 drives the bucket 5 on the extrusion plate 15 to move downwards, and then the bucket 5 pushes the asphalt. At the same time, the downward movement of the bucket 5 drives the control structure 8 to move downwards through the conveying pipe 7, so that the conveying port 801 on the control structure 8 is connected to the discharge port 302 on the receiving structure 3. When some asphalt moves to the connecting plate 10 on the bucket 5 and is extruded, the connecting plate 10 is pushed to move. Then, the connecting plate 10 drives the baffle 12 to block the conveying pipe 7 through the connecting rod 11. At the same time, the downward movement of the bucket 5 drives the second pulley 204 on the transmission structure 2 to move downwards, so that the belts on the first pulley 203 and the second pulley 204 are in a taut state. Then the vehicle body 1 moves so that the wheels 1 9 is driven by the belts on the first pulley 203 and the second pulley 204. Then, the second pulley 204 drives the bidirectional auger 6 to rotate through the second rotating rod 202, thereby spreading excess asphalt to both sides of the bucket 5. When the spread asphalt becomes less, the connecting plate 10 lacks asphalt compression, so the connecting plate 10 is reset by the connecting telescopic rod 901 and the reset spring 902 on the reset structure 9. Then, the connecting plate 10 pushes the opening 13 on the baffle 12 into the inside of the conveying pipe 7. Then, the conveying pipe 7 opens to add asphalt to the connecting plate 10 for replenishment. When the use is over, the electric telescopic rod 20 drives the extrusion plate 15 to move upward. Then, when the extrusion plate 15 moves upward through the bucket 5, it drives the second pulley 204 to move upward. At this time, the belt between the first pulley 203 and the second pulley 204 is in a loose state and does not transmit power.
