The electric push rods drive the insert plate to move, and then discharge the raw materials.

The three-side inclined surfaces of the picking plate are used to move the raw materials at the bottom, thereby improving the mixing effect of the raw materials and facilitating stirring.

[0025] It should be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0026] In the present invention, by stacking the fixed raw materials together, the raw materials can be preliminarily mixed before entering the mixing drum, and then the asphalt is sprayed on the fallen raw materials, thereby improving the subsequent mixing efficiency.

[0027] In the present invention, filter plates are installed at the bottom of multiple storage hoppers to filter the raw materials, preventing unqualified large particles of raw materials from entering the mixing drum. At the same time, the filter screen moves back and forth under the drive of the sliding frame, so that the filtered raw materials fall quickly.

[0028] In the present invention, by setting the material dividing mechanism, when the raw materials are on the conveyor, the mounting frame drives the pressing plate and the lifting plate to move, and the three side inclined surfaces of the lifting plate are used to move the raw materials at the bottom, thereby improving the mixing effect of the raw materials and facilitating stirring;

[0029] In the present invention, a rotatable scraper is installed in the mixing drum, so that the scraper can scrape off the raw materials adhering to the inner wall of the mixing drum, thereby preventing the raw materials from sticking to the wall.

[0030] In the present invention, the raw materials can be preliminarily mixed before entering the mixing drum, and then asphalt is sprayed on the fallen raw materials, thereby improving the subsequent mixing efficiency. At the same time, the raw materials can be filtered through the filter plate to prevent unqualified large particles of raw materials from entering the mixing drum. At the same time, the filter screen moves back and forth under the drive of the sliding frame, so that the filtered raw materials fall quickly. The three-side inclined surfaces of the picking plate are also used to move the raw materials at the bottom, thereby improving the mixing effect of the raw materials and facilitating stirring.
