In addition, the roller can rotate between the first stirring blades under the push of the aggregate, thereby driving the second stirring blade to rotate, improving the stirring effect, and improving the mixing effect of the building materials. The scraper rod can be used to scrape off the aggregate adhering to the inner wall of the mixing hopper to prevent the aggregate from adhering and accumulating on the inner wall of the mixing hopper, thereby improving the stirring effect and improving the mixing effect of the building materials.
