Control time for an implement which has a structure of lifting controlled hydraulic, and control structure of the time

摘要

Control time for an implement which has a structure of lifting controlled hydraulic, and control structure of the time. A depth control system, particularly useful for depth control of a single point on an agricultural implement.It includes a valve and actuator mounted directly to the areas of pivot connection of a hydraulic cylinder which controls the time.The movement of the cylinder directly controls the actuation of the valve independently of the joints are complicated, in order to reduce the size and cost of the system and overcome, substantially.The problems of hysteresis.
