when B is less than B0, the controller judges that the mixing and stirring are insufficient and continues the stirring process;

when B is larger than or equal to B0, the controller judges that the mixing and stirring are finished and terminates the mixing and stirring.

Specifically, the controller of this embodiment judges the mixing and stirring degree by comparing the air humidity B in the mixing tank detected in real time with the preset standard air humidity B0, and can effectively ensure the sufficiency of stirring by judging and controlling the termination of stirring, thereby improving the production efficiency of the tubular pile.

Specifically, after the mixing and stirring are completed, the controller compares the gas temperature T in the mixing tank with each preset gas temperature, and controls the stirring rod to perform compensation stirring according to the comparison result, wherein,

when T is less than T1, the controller controls the stirring rod to stir at a preset compensation stirring speed Va1 and a compensation stirring time p 1;

when T1 is less than or equal to T < T2, the controller controls the stirring rod to stir at a compensation stirring speed Va2 and a compensation stirring time p2, wherein Va2 is set as Va1 x [1- (T-T0)/T0], and p2 is set as p1 x [1- (T-T0)/T0 ];

when T is more than or equal to T2, the controller judges that the mixing and stirring are sufficient and does not perform compensation stirring;

wherein T1 is a first predetermined gas temperature, T2 is a second predetermined gas temperature, and T1 is less than T2.

Specifically, after the compensation stirring is completed, a part of the stirred mixture is taken out for viscosity detection, and the detection result is input into a controller, and the controller judges the mixture according to the input detection result, wherein,

when the viscosity of the mixed material does not meet the requirement, the controller controls the stirring rod to perform secondary mixing and stirring on the mixed material;

when the viscosity of the mixed material meets the requirement, the controller controls the electronic valve to output the mixed material.

Particularly, this embodiment the controller is right according to the testing result of input the misce bene judges, can effectively guarantee through judging whether viscosity accords with the standard that the batching after the stirring accords with the demand to improve the production efficiency of tubular pile.

Specifically, when the secondary mixing and stirring is performed, the controller sets the stirring speed Vv of the stirring rod according to the viscosity H of the mixture, sets Vv ═ Vj × [1+ (H0-H)/H0], sets Vv 0 as the standard viscosity, adjusts the standard air humidity to B0 ', B0' ═ B0 × [1+ (H0-H)/H0, and repeats the determination process of the mixing and stirring degree until the viscosity of the mixture meets the requirement.
