Skid and sink and reduced the trafficability characteristic and the operability of tractor, increased fuel consumption, can cause the unable walking operation of tractor when serious, reduced the operating efficiency of tractor under the paddy field environment, and then influenced the cost of paddy field grain output.

The tractor slip rate detection device can be directly tested and completed without influencing mechanical working conditions, and the test result is accurate. In addition, in the prior art, the slip ratio of the conventional vehicle is calculated by measuring the rotating speed of the driving spindle and the speed of the vehicle body. The rotating speed of the driving main shaft is measured by a reflective infrared photoelectric sensor near the driving main shaft, and the speed of the vehicle body is measured by satellite positioning (GPS, RTK) or a five-wheel instrument and other methods. However, in a paddy field environment, a tractor walking system is easy to splash muddy water in the paddy field to the vicinity of a driving spindle, a light diffuse reflection phenomenon or a light source shielding phenomenon is generated, detection errors are increased or detection light signal reading failure is caused, and the problems of zero offset drift, high cost and the like exist by utilizing satellite positioning.
In the prior art, the sinking depth is obtained by measuring the distance between a certain fixed point of the vehicle body and a certain reference surface (such as the ground). However, the reference surface in the paddy field is the water surface, the water surface can generate diffuse reflection phenomenon to the propagation of media such as light, ultrasonic waves and the like, and meanwhile, the water surface can be influenced by a tractor walking system to fluctuate greatly all the time, so that accurate distance values cannot be obtained by adopting methods such as laser, ultrasonic waves, vision and the like.
