Claims

[Claim for Utility Model Registration] The height of the work equipment above the ground is detected by a sensor, and the amount of movement of the sensor is transmitted via a link to a hydraulic control arm, which controls the work equipment to move up and down to maintain a constant plowing depth. In the automatic plowing depth control device, the link. The link has a two-fold structure that can mutually rotate around a pivot shaft, and both links are configured to be freely connected and disconnected by a hook and a retaining part, and a lever is interlocked with the hook,
Further, a toggle spring is stretched between the lever and a link connected to the sensor, and when the sensor is raised by a predetermined amount, the biasing direction of the toggle spring is switched in a direction in which the hook engages with the engaging portion. A release device for an automatic plowing depth control device configured as follows.
