[0025] The both sides of connecting frame 6 are seted up to be inclined plane, and the inside of insertion slot 621 is cylindrical, and the opening width of insertion slot 621 is less than the diameter of cylindrical shape;
[0026] The mounting hole 221 on the shaft 22 is seted up with multiple groups, and the mounting hole 221 in the middle of shaft 22 is installed with stirring frame 7 through bolt;
[0027] The mounting hole 221 of the end of shaft 22 is installed with fixed frame 5 through bolt, and the fixed frame 5 is installed with scraper 51 using bolt in one end, and the scraper 51 is inclined, and is attached with the inner wall of one end of heating cylinder 12.
[0028] Specifically, motor 21 starts, and the output end drives the rotation of the shaft 22, and the connecting frame 6 rotates with the shaft 22, and the connecting frame 6 drives the rotation of the removal frame 62 through the connecting arm 622, and since the removal plate 63 is attached with the inner wall of heating cylinder 12, so the removal frame 62 will drive the removal plate 63 to make circular motion along the inner wall of heating cylinder 12, and the asphalt concrete adhered on the inner wall of heating cylinder 12 during drying is removed in real time, to prevent a large number of attachments from forming a barrier layer to affect the drying effect;
[0029] The stirring frame 7 installed in the middle of the shaft 22 also rotates with the shaft 22, and the asphalt concrete in the heating cylinder 12 is stirred, so that the internal material can be heated more evenly, further improving the drying efficiency and quality, avoiding the occurrence of local overheating or overwetting, and the fixed frame 5 at the end of the shaft 22 and the scraper 51 installed on one end thereof also rotate with the shaft 22, the scraper 51 is inclined and attached with the inner wall of one end of the heating cylinder 12, and the material on the inner wall of one end of the heating cylinder 12 can be scraped during rotation, and the removal plate 63 makes the material flow better, and also prevents the material from accumulating on the inner wall of the end of the heating cylinder 12;

[0031] The connecting frame 6 is provided with inclined surfaces on both sides, which can also mix the asphalt concrete. The inner side of the insertion slot 621 is cylindrical and the opening width is smaller than the diameter of the cylinder, which can make the connection between the cleaning plate 63 and the cleaning frame 62 more stable, and can withstand greater torsion and pressure during equipment operation, ensuring the normal operation of each component, while having certain flexibility, facilitating installation and disassembly and maintenance.
