step S3: the crawler belt runs from the feed inlet to the stirrer, and waste soil is transported to the stirrer from the feed inlet;
step S4: closing the second valve, and enabling the external air pressure equipment to ventilate into the ventilation pipe, wherein the ventilation pipe injects air into the first connecting rod through the first valve, the air pressure in a sealed communication structure formed by the first connecting rod and the second connecting rod is increased, the second connecting rod is pushed out towards the track, and waste soil is hit;
step S5: closing external air pressure equipment, opening the second valve by rotating a flywheel of the second valve, reducing air pressure in the communication structure, and rebounding the second connecting rod towards the closed end of the first connecting rod under the action of the tension of a spring;
step S6: when the first valve is opened, the second valve is closed, when the first valve is closed, the second valve is opened, the first valve and the second valve are mutually matched, the pneumatic soil breaking hammer moves up and down to hit the waste soil on the track, and the additive and the waste soil are subjected to preliminary hit mixing;
step S7: starting the stirrer, rotating the main shaft, stirring and mixing the waste soil in the stirrer with the additive for the second time by the stirring rod, and taking out the mixed waste soil from the soil taking port.
9. The intelligent doping method of the automatic waste soil crushing device according to claim 8, wherein: in step S2, the console processing system calculates the corresponding admixture blending amount according to the volume water content, and the specific calculation method is as follows:
step S21: after the waste soil passes through the soil moisture probe, different voltages are output, and the relation equation between the volume water content of the waste soil and the output voltage is that
ω＝aV+b
Wherein ω is the soil volume moisture content, V is the output voltage, a, b are coefficients, respectively, each soil moisture probe has a specific calibration curve through which the values of a and b can be found;
step S22: the console processing system calculates the mixing amount of the additive, and the calculation formula is as follows
Wherein x is the doping amount of the additive, omega is the water content of the soil volume, omega i For the water content limit value given in the specification, x i The limits for the amounts of admixture incorporated are given in the specification.
