Real-time performance detection device for straw pulverizer matched with combine harvester for use

The invention provides a real-time performance detection device for a straw pulverizer matched with a combine harvester for use. The real-time performance detection device comprises a power input device, a torque detection device, a rotating speed detection device, a data acquisition unit, a data processing device and a power supply unit. The torque detection device is used for detecting the torque of a driving shaft of the straw pulverizer. The rotating speed detection device is used for detecting the rotating speed of the driving shaft of the straw pulverizer. The data acquisition unit is used for receiving signals sent by the torque detection device and the rotating speed detection device and transmitting the signals to the data processing device. The data processing device is used for calculating, displaying and storing the torque, the rotating speed, the power and the power consumption of the straw pulverizer in the actual working state in real time according to the received signals. The power supply unit is used for supplying voltages to the torque detection device, the rotating speed detection device and the data processing device. The real-time performance detection device is simple and compact in structure, the detected data are accurate and high in precision, and the performance of the straw pulverizer in the actual working process can be detected directly.
