The invention discloses an automatic weighing method for a concrete mixer. The automatic weighing method for the concrete mixer comprises the steps that whether the rotating speed of a motor is stabilized at a first rotating speed n1 or not is judged; if yes, determining a first torque t1 of the motor within a first set time; judging whether the rotating speed of the motor is stabilized at a second rotating speed n2; if yes, determining a second torque t2 of the motor within a second set time; determining the weight of the concrete according to (n1, t1), (n2, t2) and the motor rotating speed-motor torque-concrete weight coordinate graph; or determining the weight of the concrete according to (n1, t1) and the motor rotating speed-motor torque-concrete weight coordinate graph; and determining the collapse degree of the concrete according to the (n1, t1), (n2, t2) and the motor rotating speed-motor torque-concrete collapse degree coordinate graph. According to the automatic weighing method for the concrete mixer
