The utility model can scrape the inner wall of the mixing box by installing a cleaning component and a scraper. When the asphalt is heated, it is a semi-liquid or liquid state with high viscosity, which makes it easy for a part of the asphalt to adhere to the inner wall of the mixing tank. The first motor is started, and its output end drives the screw rod to rotate on the inner wall of the bearing. Because the screw rod is meshed with the slide groove, the rotation of the screw rod will drive the scraper to move through the slide groove and the sliding block, and the scraper will scrape the asphalt adhered to the inner wall of the mixing tank during the movement, which can effectively avoid the waste of materials and prevent the asphalt from solidifying on the inner wall of the mixing tank, which increases the difficulty of subsequent cleaning work and makes the cleaning of subsequent staff more convenient.

The asphalt material can be easily added to the inside of the tank body 4 through the auxiliary guidance of the feed hopper 52 without opening the entire top cover 51, thereby simplifying the operation process and improving work efficiency. At the same time, the design that the bottom of the feed hopper 52 passes through the top cover 51 also ensures that the asphalt material can directly and smoothly enter the inside of the tank body 4, avoiding material waste and pollution.

[0035] Principle and advantages of use: By setting up the stirring mechanism 5, during the use of the device, the material can first be added into the tank body 4 at the bottom of the top cover 51 through the feed hopper 52, and then the fourth motor 53 can be started to run, and the fourth motor 53 can drive the rotating shaft 54 ​​to rotate, and the rotation of the rotating shaft 54 ​​can assist in driving the stirring frame 55 and the auger 56 to rotate. The stirring frame 55 can rotate to stir and mix the inside of the tank body 4, and the auger 56 can be driven to rotate by the rotating shaft 54 ​​during the stirring and mixing process, and the material can be rolled and transported from bottom to top when the auger 56 rotates in the reverse direction. , so that the materials can be efficiently mixed and stirred. After the stirring and mixing is completed, the third motor 83 can be started to run. The operation of the third motor 83 can drive the shaft 84 to rotate, and the shaft 84 can be driven to rotate inside the discharge frame 82. At this time, the shaft 84 can assist in driving the discharge baffle 85 to rotate. By rotating and flipping the discharge baffle 85, the asphalt material inside the discharge frame 82 can be evenly discharged onto the ground. At this time, by driving the auger 56 to rotate in the forward direction, the material can be conveyed from top to bottom, so that the material can be discharged quickly and stably, which is convenient for asphalt pouring;

[0036] By arranging the pressure mechanism 7 to cooperate with the cleaning mechanism, when the asphalt material is discharged through the discharge assembly 8 during use, the first motor 613 can be started to operate, and the operation of the first motor 613 can drive the screw rod 612 to rotate, and the rotation of the screw rod 612 can drive the sliding block 614 to slide on the inner side of the displacement bottom rail 611, and the sliding of the sliding block 614 can assist in driving the bottom plate 641 to move horizontally, and the horizontal movement of the bottom plate 641 can assist in driving the first cylinder 643 to move horizontally, and the horizontal displacement of the first cylinder 643 can assist in driving the scraper plate 644 to move horizontally. At this time, the equipment is pushed to reciprocate on the top of the discharged material. During this period, the material can be spread flat by the movement of the scraper plate 644, and the operation of the second cylinder 72 can push the pressing roller 74 to fit the top of the material for pressing and rolling. The first cylinder 643 and the second cylinder 72 are used to work together, and then the vehicle is used to drive the equipment to move back and forth on the road, so that the material can be evenly spread. During the first paving process of the vehicle, the cleaning brush plate 65 at the bottom of the second motor 652 3 will first contact the ground, and the ground can be brushed and cleaned by starting the second motor 652. The cleaning brush plate can assist in brushing, which can improve the overall cleaning effect of the device. During the use of the equipment, under normal circumstances, a single or several lateral displacements of the scraper plate 644 obviously cannot cause the material to be laid flat. Therefore, during use, the device will be operated to reciprocate and move on the top of the material just discharged, which can cause the asphalt material to be quickly laid flat, and also make the pressure roller 74 repeatedly press the asphalt to make it more compact. At the same time, in this process, the second motor 652 is started in advance to drive the cleaning brush plate to rotate, so that the ground can be cleaned, which is convenient for the operation and use of the device. During the cleaning period, it is necessary to ensure that the cleaning brush plate 653 and the asphalt material have no contact when the equipment reciprocates. The connecting rod 651 can be set with a longer connecting rod 651 with a larger span, which can improve the scraping formation of the scraper plate 644, and can be adjusted as needed during specific use. During the use of the device, after the asphalt material is discharged, the device reciprocates and moves on the top of the asphalt material to maintain a good flat pressing effect.
