The utility model discloses a platform triggering return control mechanism. The platform triggering return control mechanism comprises a framework, a main shaft, a triggering mechanism, a first retainer ring, a second retainer ring, a first spring, a second spring, a return mechanism, a shifting plate assembly, a return arm, a rotating block, a push plate assembly and a valve core push rod which is connected with a hydraulic valve; the triggering mechanism rotates, drives the shifting plate assembly, the return arm and the rotating block to move and compresses the first spring, so that the first retainer ring drives the valve core push rod to move forwards, and the hydraulic valve is triggered to work; the return mechanism rotates, drives the push plate assembly, the return arm and the rotating block to move and compresses the second spring, so that the second retainer ring drives the valve core push rod to move backwards, and the hydraulic valve is driven to return. The platform triggering return control mechanism is triggered through a rectangular bale to control the platform to automatically overturn and control the platform to automatically fall back after rotating for a given angle.
