The specific implementation mode is as follows: when the mixer designed by the invention is used, the filling opening 32 opened on the mixing shell 2 is upward through the adjusting mechanism 3 before use; then, the raw material of the concrete is loaded into the stirring shell 2 through a loading mechanism through a filling opening 32 on the stirring shell 2; after the charging is finished, controlling the first driving motor 8 and the third driving motor 11 to work, so that the first driving motor 8 can drive the first rotating shaft 19 to rotate forwards through an output shaft on the first driving motor; the first rotating shaft 19 rotates to drive the second gear 13 to rotate; the second gear 13 rotates to drive the first gear 12 to rotate; the first gear 12 rotates to drive the fourth gear 17 to rotate; the fourth gear 17 rotates to drive the corresponding fixed ring 15 to rotate through the corresponding first shaft sleeve 25; the fixed ring 15 rotates to drive the spiral stirring sheet 9 to rotate; the concrete raw materials are stirred by the rotation of the spiral stirring sheet 9; meanwhile, the third driving motor 11 drives the threaded rod 24 to rotate in the positive direction through an output shaft on the third driving motor; the threaded sleeve 30 will move along the threaded rod 24 under the cooperation of the external thread on the threaded rod 24 and the internal thread on the threaded sleeve 30; the threaded sleeve 30 moves to drive the connecting rod 27 to move; the connecting rod 27 moves to drive the arc-shaped scraping blade 16 arranged on the connecting rod to move; the concrete stuck on the inner circular surface of the stirring shell 2 is cleaned through the movement of the arc-shaped scraping blade 16, so that the whole effect is prevented from being influenced due to insufficient stirring of the concrete; after the spiral stirring piece 9 rotates n circles, the first driving motor 8 and the third driving motor 11 are controlled to enable the first driving motor 8 to drive the first rotating shaft 19 to rotate reversely; the third driving motor 11 drives the threaded rod 24 to rotate reversely; so that the arc-shaped blade 16 is moved toward the original position; when the arc-shaped scraping blade 16 moves to the original position, the third driving motor 11, the second driving motor 10 and the first driving motor 8 are controlled to enable the rotation of the threaded rod 24 and the rotation of the fixed sleeve 26 to be relatively static, and the spiral stirring blade 9 and the arc-shaped scraping blade 16 rotate together towards the same direction for 15-20 degrees; then, the first driving motor 8 and the third driving motor 11 are controlled to work again, so that the first driving motor 8 drives the first rotating shaft 19 to rotate forwards; the third driving motor 11 drives the threaded rod 24 to rotate in the forward direction. After the concrete is stirred, a filling opening 32 formed in the stirring shell 2 is downward through the adjusting mechanism 3; pouring the stirred concrete out of the stirrer.
