The forced mixer is composed of a barrel, a frame, a motor, a reducer, a rotating arm, a mixing shovel, and a cleaning scraper. The angle between the working surface of the mixing shovel and the forward direction in the vertical and horizontal directions is an obtuse angle, which can strengthen the mixing effect and improve the mixing quality. The discharge port is set on the side wall of the barrel, and a cleaning scraper is set to speed up the discharge more thoroughly and reduce leakage. The walking wheels are easy to produce, and the wheelbase is adjustable, which makes the mixer more convenient to move. The stirring shaft of the machine does not bear pressure during the process of mixing materials, and the maintenance is simple and convenient.
