Tank body stirred material treatment system, stirring truck and tank body stirred material weighing method

The invention provides a tank body stirred material processing system which comprises a vehicle body, a stirring barrel, a speed reducer, a flange, a force sensor and at least one attitude sensor, the stirring barrel, the speed reducer, the flange, the force sensor and the attitude sensor are obliquely arranged on the vehicle body, the speed reducer is connected with the stirring barrel through the flange, the central axis of the flange coincides with the central axis of the stirring barrel, and the force sensor and the attitude sensor are installed on the vehicle body. The force sensor obtains the axial force F borne by the flange, the attitude sensor obtains the included angle alpha between the central axis of the flange and the horizontal direction of the vehicle body and the acceleration a of the mixing drum in the driving direction, and the actual weight m1 of a stirred object in the mixing drum can be calculated according to the Newton second law. According to the tank body stirred object treatment syst
