Device and method for measuring and calibrating ground pressure of seeding depth limiting wheel

The invention relates to the technical field of agricultural seeding, and provides a seeding depth wheel ground pressure measuring and calibrating device and a seeding depth wheel ground pressure measuring and calibrating method. According to the device for measuring and calibrating the ground pressure of the seeding depth limiting wheels, a machine body is connected with a pair of depth limiting wheels; the pressure adjusting piece is arranged on the machine body and used for adjusting the pressure of the depth limiting wheel on the ground; the pressure sensor is arranged on the machine body and used for detecting the actual pressure output by the pressure adjusting piece. The pressure acquisition calibrator is used for detecting the ground pressure applied to the ground by the depth limiting wheel; and the pressure acquisition calibrator is also used for automatically fitting a plurality of actual pressures and a plurality of ground pressures and then establishing a depth wheel ground pressure measurement m
