Thanks to the arrangement of the motor 110 and the mixing barrel 101, the motors 110 in the two mixing components 1 can be started in forward and reverse rotations respectively, so that the motor shafts of the motors 110 in the two mixing components 1 can be rotated in forward and reverse rotations respectively. With the help of the arrangement of the roller bearing 3, the two mixing barrels 101 can be rotated relative to each other, so that the soil and rocks in the two mixing barrels 101 can be rotated in a staggered manner, which is beneficial to increase the degree of confusion between the soil and rocks, and further improve the mixing effect of the soil and rocks.

[0024] To ensure the rotation stability of the mixing barrel 101, Figure 1 and Figure 4 As shown, the inner edge surface of the support ring 104 is rotatably connected to the outer edge surface of the mixing barrel 101 , and a ball bearing is provided at the connection between the inner edge surface of the support ring 104 and the mixing barrel 101 .
