AI Technical Summary

Technical Problem

Existing mixer trucks cannot directly measure the actual mass of the material being mixed, and the mass of the material calculated using the torque balance method has a large error when the center of gravity or density of the material changes.

Method used

A tank-based agitation system is used. By installing force and attitude sensors inside the reducer, the actual mass of the agitated material is calculated using Newton's second law. The formula is: where is the sum of the weights of the agitator and the agitated material. The mass of the agitated material is calculated using the axial force and acceleration acting on the flange.

Benefits of technology

It enables direct calculation of the mass of the stirred substance, reduces the influence of changes in the center of gravity and density, and improves measurement accuracy and applicability to a wider range of working conditions.

Abstract

This invention provides a tank-type material handling system, including a vehicle body and an inclined mixing drum, a speed reducer, a flange, a force sensor, and at least one attitude sensor. The speed reducer is connected to the mixing drum via the flange, with the central axis of the flange coinciding with the central axis of the mixing drum. The force sensor and attitude sensor are respectively mounted on the vehicle body. The force sensor acquires the axial force F acting on the flange, and the attitude sensor acquires the angle α between the central axis of the flange and the horizontal direction of the vehicle body, as well as the acceleration a of the mixing drum in the direction of travel. The actual mass m1 of the material being mixed inside the mixing drum can be calculated using Newton's second law. This tank-type material handling system can solve the errors caused by changes in the center of gravity or density of the material when measuring its actual mass in existing technologies, thus improving the accuracy of the measurement. This invention also relates to a mixing truck and a method for determining the actual mass of the material being mixed.
