[0002] A mixing device for asphalt concrete production is a piece of equipment used to mix asphalt, aggregates and other auxiliary materials. It is widely used in road construction and engineering construction. With the advancement of urbanization and the increasing demand for transportation construction, asphalt concrete has been widely used as a common road material.

[0003] When using an asphalt concrete mixing plant, asphalt and other auxiliary materials are directly fed into the mixing plant through the feed hopper for mixing. However, when powdery raw materials such as asphalt are fed into the mixing plant from the feed hopper, the asphalt bags need to be opened and the asphalt needs to be poured into the mixing plant manually. This process generates a lot of dust, which workers can inhale for extended periods, affecting their health. Therefore, a mixing plant for asphalt concrete production has been proposed.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Please refer to the following: Figures 1-7This utility model provides a technical solution: a mixing device for asphalt concrete production, comprising: a base plate 100, a mixing tank 200, and a feeding assembly 300. The mixing tank 200 is disposed above the base plate 100, and the feeding assembly 300 is disposed at the front end of the mixing tank 200. The feeding assembly 300 is used to convey raw materials into the mixing tank 200. During feeding, the mixing tank 200 and the feeding assembly 300 are in an inclined state. Specifically, when conveying raw materials, the mixing tank 200 is in an inclined state, and the feeding assembly 300 is also inclined. By conveying raw materials into the feeding assembly 300, the raw materials are conveyed into the mixing tank 200. When asphalt is conveyed into the mixing tank 200 through the feeding assembly 300, the packaging bag is directly conveyed into the inside of the feeding hopper 301. At this time, the operator can stay away from the feeding end, and there is no need for manual dumping, which reduces the impact of dust on the workers.

[0028] Furthermore, the feeding assembly 300 includes a feeding hopper 301 connected to the front end of the mixing tank 200. First electric push rods 302 are installed on both sides of the feeding hopper 301. The output ends of the first electric push rods 302 extend into the interior of the feeding hopper 301 and are equipped with hooks 303 for scraping the asphalt packaging bags. An mounting plate 304 is provided on the exterior of the feeding hopper 301 near the mixing tank 200. A second electric push rod 305 is installed at the output end of the mounting plate 304. A guide bucket 306 is installed at the output end of the second electric push rod 305. The second electric push rod 305 drives the guide bucket 306 to push the asphalt packaging bags out of the feeding hopper 301. Specifically, when conveying asphalt, the first electric push rods 302 operate, and the two first electric push rods 302 respectively drive two... The hook blades 303 are positioned at the center of the feed hopper 301, directly conveying the asphalt packaging bag into the feed hopper 301. Under the influence of gravity, the hook blades 303 puncture the asphalt packaging bag, and the first electric push rod 302 retracts, causing the hook blades 303 to cut the asphalt packaging bag, allowing the asphalt to enter the mixing tank 200. After the asphalt is fed, the second electric push rod 305 is activated, driving the guide bucket 306 to move upwards, pushing the asphalt packaging platform out of the feed hopper 301 and removing the packaging bag. Thus, during feeding, the packaging bag is directly conveyed into the feed hopper 301, allowing workers to stay away from the feeding end and eliminating the need for manual emptying, reducing the impact of dust on workers.

[0029] Furthermore, the mixing tank 200 has a drive assembly on its exterior for rotating the mixing tank 200. The drive assembly includes an L-shaped plate 400, which is rotatably fitted onto the exterior of the mixing tank 200. A motor 401 is mounted on the outer surface of the L-shaped plate 400. A support shaft is fixedly connected to the output end of the motor 401. A gear 402 is fixedly fitted onto the outer surface of the support shaft. A gear ring 403 is fitted onto the outer surface of the mixing tank 200. The gear 402 and the outer surface of the gear ring 403 are movably meshed. Specifically, during mixing, the motor 401 drives the support shaft to rotate, causing the gear 402 to rotate. The gear 402 drives the gear ring 403 to rotate. The rotation directions of the gear 402 and the gear ring 403 are opposite. The gear ring 403 drives the mixing tank 200 to rotate, so that the material inside the mixing tank 200 is in a dynamic state.

[0030] The feed hopper 301 is externally equipped with a power supply for supplying power to the first electric push rod 302 and the second electric push rod 305. This allows the power supply and the first electric push rod 302 and the second electric push rod 305 to rotate simultaneously when the drive assembly drives the mixing tank 200 to rotate. The power supply and the first electric push rod 302 and the second electric push rod 305 are in a relatively stationary state, which facilitates the wiring for supplying power to the first electric push rod 302 and the second electric push rod 305.

[0031] Furthermore, the outer surface of the base plate 100 is provided with a support assembly for supporting the mixing tank 200. The support assembly includes two support plates 501 arranged symmetrically front to back. A rotating ring 502 is rotatably connected between the outer surfaces of the two support plates 501. The mixing tank 200 rotates through the interior of the rotating ring 502. Specifically, the mixing tank 200 is supported by the support assembly. When the mixing tank 200 is tilted, the rotating ring 502 rotates between the two support plates 501. When the mixing tank 200 rotates, the mixing tank 200 rotates within the inner ring of the rotating ring 502.

[0032] Furthermore, the top outer surface of the base plate 100 is provided with a pushing assembly for pushing the mixing tank 200 to an inclined state. The pushing assembly includes two rotating seats, which are respectively installed at the bottom of the L-shaped plate 400 and the top of the base plate 100. A cylinder 500 is rotatably installed between the two rotating seats. Specifically, during feeding and discharging, the cylinder 500 works, and the two ends of the cylinder 500 rotate between the two rotating seats. The cylinder 500 pushes the L-shaped plate 400, applying upward force to one end of the mixing tank 200, so that the mixing tank 200 is in an inclined state.

[0033] Furthermore, the mixing tank 200 is equipped with a mixing assembly for mixing the raw materials inside the mixing tank 200. The mixing assembly includes a mixing shaft 600 and multiple sets of mixing blades 601. The mixing shaft 600 rotates through the front outer surface of the mixing tank 200, and the multiple sets of mixing blades 601 are evenly distributed outside the mixing shaft 600. Specifically, the mixing shaft 600 and the mixing tank 200 rotate in opposite directions. When the mixing shaft 600 rotates, it drives the mixing blades 601 on it to rotate, thereby mixing the raw materials inside the mixing tank 200.

[0034] Furthermore, a transmission assembly for driving the rotation of the stirring shaft 600 is provided between the stirring shaft 600 and the support shaft. The transmission assembly includes two synchronous pulleys 700, which are respectively disposed outside the stirring shaft 600 and the support shaft. A synchronous toothed belt 701 is wound around the two synchronous pulleys 700 to drive the two synchronous pulleys 700. Specifically, the transmission assembly causes the stirring shaft 600 to rotate with the rotation of the support shaft. At this time, when the motor 401 drives the support shaft to rotate, it drives the synchronous pulley 700 on it to rotate. Under the action of the synchronous toothed belt 701, it drives the other synchronous pulley 700 to rotate, thereby causing the support shaft and the stirring shaft 600 to rotate simultaneously.

[0035] Furthermore, the guide bucket 306 is umbrella-shaped, and the outer surface of the mounting plate 304 is provided with a strip-shaped through hole. Specifically, the umbrella-shaped guide bucket 306 guides the asphalt to avoid asphalt accumulation at the second electric push rod 305. The strip-shaped through hole allows the asphalt to pass through the mounting plate 304, preventing asphalt from accumulating on the mounting plate 304.

[0036] Working Principle: In use, this invention pushes the mixing tank 200 to an inclined state via a pushing component. At this time, the cylinder 500 operates, its two ends rotating between two rotating seats. The cylinder 500 pushes the L-shaped plate 400, applying upward force to one end of the mixing tank 200, thus tilting the tank and conveying raw materials from the feeding component 300 into the mixing tank 200. When conveying asphalt, the first electric push rod 302 operates, driving two hook blades 303 to position them at the center of the feeding hopper 301, thus packaging the asphalt. The bag is directly conveyed into the feed hopper 301. Under the action of gravity, the hook 303 punctures the asphalt packaging bag, and the first electric push rod 302 retracts, causing the hook 303 to cut the asphalt packaging bag, allowing the asphalt to enter the mixing tank 200. After the asphalt is fed, the second electric push rod 305 is activated, driving the guide bucket 306 to move upward, causing the guide bucket 306 to push the asphalt packaging platform out of the feed hopper 301 and remove the packaging bag. Thus, during feeding, the packaging bag is directly conveyed into the feed hopper 301. At this time, the operator can stay away from the feeding end, and there is no need for manual dumping, reducing the impact of dust on the workers.

[0037] During mixing, the motor 401 operates, driving the support shaft to rotate, which in turn rotates the gear 402. The gear 402 drives the gear ring 403 to rotate, with the gear 402 and gear ring 403 rotating in opposite directions. The gear ring 403 drives the mixing tank 200 to rotate, causing rotation within the rotating ring 502. When the gear 402 rotates, it drives the support shaft to rotate, which in turn drives the synchronous pulley 700 on it to rotate. The synchronous pulley 700 drives the synchronous toothed belt 701 to rotate, causing another synchronous pulley 700 to rotate, thereby driving the mixing shaft 600 to rotate. The mixing shaft 600 drives the mixing blades 601 to rotate, mixing the raw materials inside the mixing tank 200. The mixing shaft 600 rotates in the opposite direction to the mixing tank 200, improving the mixing effect. After mixing is completed, the mixing tank 200 is tilted by pushing the components, allowing the asphalt concrete inside the mixing tank 200 to be discharged.
