Dynamic measurement system and dynamic measurement method of stabilized soil stirring equipment

Abstract

The invention belongs to road surface engineering machinery and a control method thereof, in particular to dynamic measurement system and dynamic measurement method of stabilized soil stirring equipment. The measurement system comprises a belt conveyer and a hopper, wherein the belt conveyer is driven by a drive motor, the hopper can discharge materials to a material delivery belt of the belt conveyer, a support roller of the material delivery belt is provided with a weighing sensor which can detect the pressure of the support roller, a rotating shaft of a driven wheel of the belt conveyer isconnected with a counting wheel, a speed measurement sensor which is matched with the counting wheel is arranged beside the counting wheel, the detection signals of the weighing sensor and the speed measurement sensor are input into an industrial control computer, and a control signal of the industrial control computer controls the drive motor of the belt conveyer by a frequency converter. The system has double advantages of volume measurement and weighing measurement, enhances the measurement accuracy and the reliability, lowers the equipment cost, can realize real-time automatic control andhas high degree of automation and convenient operation.

Description

technical field [0001] The invention belongs to road construction machinery and a control method thereof, and relates to a dynamic metering system and a dynamic metering method of a stabilized soil mixing device. Background technique [0002] The traditional stabilized soil mixer system usually adopts two ways to control the batching: one is to measure the volume, according to a certain size of the material door, the unit flow rate of the motor running at different speeds is calibrated, and the speed and flow rate are calculated. The average proportional coefficient is dynamically measured according to the average proportional coefficient. This method has poor measurement accuracy and cannot meet the needs of high-standard users. Another way is to use special weighing instruments. This way has defects such as complex system, poor reliability, inability to realize some complex control functions, high maintenance rate, high equipment cost, complicated operation and calibration...
