[0023] Specifically, the motor 62 is started, and the output end drives the worm 63 connected thereto to rotate. The rotating worm 63 is engaged with the worm gear 64. Since the worm gear 64 is fixedly installed on the rotating shaft 21, the rotation of the worm 63 is transmitted to the worm gear 64 through the engagement relationship, thereby driving the rotating shaft 21 to rotate. The rotating shaft 21 drives the rotating frame 22 fixed thereon to rotate. The rotating frame 22 is connected to the preparation tank one 7 and the preparation tank two 8 at both ends, respectively. Therefore, when the rotating frame 22 rotates, the preparation tank one 7 and the preparation tank two 8 rotate, thereby realizing the switching of the positions of the two preparation tanks and enabling them to correspond to the feeding hopper 3 and the stirring assembly 4 alternately to complete different processes such as feeding and stirring.

[0024] Through the rotating frame 22, the two preparation tanks are alternately driven to work. When one preparation tank is stirring and preparing cement stabilized macadam, the other preparation tank can simultaneously perform feeding and discharging operations, thereby avoiding interruption in the production process, realizing continuous production, and greatly improving the utilization rate of the equipment and the overall production efficiency.

[0025] The rotating switching mode is adopted, so that the equipment only needs one feeding hopper 3 for feeding, thereby reducing the occupied space of the feeding hopper 3 and its accessory components, effectively saving the space resources of the production site, and having greater flexibility in site planning and equipment layout.

[0026] Embodiment 2:

[0027] To realize the preparation of cement stabilized macadam, please refer to Figures 1-4 On the basis of embodiment 1, the top of the fixed plate 1 is fixedly installed with a support rod 11. The feeding hopper 3 is fixedly installed at the top of the support rod 11.

[0031] Specifically, the feeding hopper 3 is fixedly installed on the support rod 11 at the top of the fixed plate 1, and is used for storing and guiding various materials required for preparing cement stabilized macadam. When feeding is needed, the materials are discharged from the feeding hopper 3 into the preparation tank one 7 or the preparation tank two 8 in the feeding position.

[0032] The stirring assembly 4 is arranged on the guide rod 12 at the top of the fixed plate 1, wherein the lifting plate 41 is adapted to the guide rod 12 through the perforations on the peripheral side of the lifting plate 41 and can slide on the guide rod 12. The electric telescopic rod 5 is fixedly installed on the fixed plate 1 and connected with both sides of the lifting plate 41, when the stirring operation is needed, the electric telescopic rod 5 is started to push the lifting plate 41 to slide downward along the guide rod 12, so that the stirring assembly 4 is lowered into the preparation tank one 7 or the preparation tank two 8, when the stirring assembly 4 is lowered to the appropriate position, the motor two 42 on the lifting plate 41 is started, the output end of the motor two 42 drives the rotating rod 43 to rotate, the stirring arms 44 equidistantly arranged at the bottom end of the rotating rod 43 rotate with the rotating rod 43, and the materials in the preparation tank are fully stirred to complete the preparation, the electric telescopic rod 5 can be used to lift the stirring assembly 4 and separate the stirring assembly 4 from the preparation tank during the switching of the preparation tank, and then the driving assembly 6 can be used to realize the switching of the preparation tank.
