Document Type and Number:
Japanese Patent JP7328143
Kind Code:
B2
Abstract:
To provide a work machine capable of highly accurately detecting a plowing depth.SOLUTION: A work machine includes: a traveling vehicle; a tillage device disposed at a rear side of the traveling vehicle and coupled via a coupling device; a distance sensor 58 mounted on the coupling device and measuring a distance to the ground; an inclination sensor 59 for detecting an inclination angle of the tillage device to the horizontal; a plowing depth calculation unit 80a1 calculating the plowing depth of the tillage device based on the distance measured by the distance sensor and the inclination angle detected by the inclination sensor; a correction setup unit 80a4 correcting a correction value based on the plowing depth calculated by the plowing depth calculation unit, when the tillage device is grounded; and a correction unit 80a5 correcting the plowing depth calculated by the plowing depth calculation unit, by the correction value set by the correction setup unit.SELECTED DRAWING: Figure 2
