[0002] Different performances and different use occasions of stabilized soil, the mixing time required during production is different. Some stabilized soil can be mixed by one stage, but some concrete needs to be mixed by two stages. If only one mixing station with a mixing machine can meet the requirement of two-stage mixing, the once-mixed material needs to be sent back to the mixing machine for secondary mixing by external material transfer, which increases cost and affects work efficiency. Currently, there is a layout form of continuous mixing by setting two mixing machines in front and back in the same mixing station, such as the utility model patent with the authorization announcement number CN210233460U, which discloses a two-stage parallel mixing device for stabilized soil mixing station. It is described that "...a set of transition belt conveyor with rollers is added above the two-stage mixing machine. By moving left and right, the transition belt conveyor directly connects or cuts off the discharge port of the upper feeding belt conveyor and the two-stage mixing device, completing the rapid switching of one-stage and two-stage mixing...". Although this method can realize single-double stage stirring switching, the transition belt conveyor is suspended in the air above the two-stage mixing machine, which affects the stability and service life of the transition belt conveyor due to long-time and powerful mixing of the mixing machine. There is also a safety risk of high-altitude operation or falling into the mixing machine during fault maintenance of the transition belt conveyor. Therefore, it is necessary to improve the single-double stage stirring switching stabilized soil mixing station. CONTENT OF THE UTILITY MODEL

The intermediate mobile conveyor is placed between the first mixing machine and the second mixing machine, and the feeding section of the intermediate mobile conveyor is placed below the discharge port of the first mixing machine. The utility model improves the single-double stage stirring switching stabilized soil mixing station. By moving the intermediate mobile conveyor installed in a low position forward and backward, the material discharged from the first mixing machine can be sent to the second mixing machine for secondary mixing or directly sent to the discharge conveyor for finished product discharge. Therefore, the need for single-double stage stirring switching during stabilized soil production can be met, and the safety risk and instability of the equipment caused by the suspension of the intermediate mobile conveyor in the air can be avoided.
