Abstract
A device for measuring and calibrating the ground pressure of the seeding depth limiting wheels includes: a main body, connected to a pair of depth limiting wheels; a pressure adjusting member, arranged on the main body and configured to adjust a pressure of the depth limiting wheels to ground; a pressure sensor, arranged on the main body and configured to detect an actual pressure output by the pressure adjusting member; and a pressure acquisition calibrator, configured to detect a ground pressure applied by the depth limiting wheels on ground; and automatically fit a plurality of actual pressures and a plurality of ground pressures to establish a model for measuring ground pressure of a pair of depth limiting wheels. The device can automatically acquire a plurality of actual pressures and a plurality of ground pressures to establish a model for measuring ground pressure of a pair of depth limiting wheels.
