Abstract

The invention provides a manual-electric integrated bale accident rotation hydraulic control device and a control method. The control device not only comprises an accident rotation manual valve group and an accident rotation hydraulic motor loop, but also comprises an accident rotation manual-electric integrated valve group, and the accident rotation manual-electric integrated valve group comprises a manual-electric integrated reversing valve, a shuttle valve, a first hydraulic control reversing valve and a second hydraulic control reversing valve. Through reversing operation of the manual-electric integrated reversing valve and logic follow-up control formed by the shuttle valve, the first hydraulic control reversing valve and the second hydraulic control reversing valve, switching, disconnection and isolation of the manual-electric integrated hydraulic loop and the manual hydraulic loop are achieved, the manual-electric integrated hydraulic loop and the manual hydraulic loop do not interfere with each other and are standby for each other, and the automation degree and reliability of system control are improved.
