[0017] (1) The present invention discloses a hydraulic reversible plow suspension device, wherein two flexible fixing components are installed at the front end of the hydraulic reversible plow in the direction of travel through a fixed crossbeam, and the flexible fixing components are connected to the tractor. When the tractor drives the hydraulic reversible plow to turn synchronously, the tractor drives the fixed frame connected thereto and the mounting vertical rod connected to the fixed frame to squeeze the same side arms of the C-shaped mounting frame 1 and the C-shaped mounting frame 2, thereby driving the C-shaped mounting frame 1 and the C-shaped mounting frame 2 to rotate to a horizontal state, and the limiting block used for limiting the mounting vertical rod releases the limiting of the mounting vertical rod.

[0018] (2) The present invention discloses a hydraulic tipping plow suspension device. When a tractor drives the hydraulic tipping plow to turn synchronously, the tractor drives the fixed frame connected thereto and the mounting vertical rod connected thereto to squeeze the same-side arms of the C-shaped mounting frame 1 and the C-shaped mounting frame 2, and the lateral shear force is converted into the rotational force of the C-shaped mounting frame 1 and the C-shaped mounting frame 2, and the outer rotating sleeve and the inner rotating sleeve connected thereto respectively, thereby driving the C-shaped mounting frame 1 and the C-shaped mounting frame 2 to rotate to a horizontal state. At this time, the outer rotating ring seat connected to the C-shaped mounting frame 1 and the outer rotating ring seat connected thereto rotate, and the C-shaped mounting frame 1 and the C-shaped mounting frame 2 rotate simultaneously. The inner rotating sleeve connected to the C-shaped mounting frame 1 and the C-shaped mounting frame 2 rotates, and the outer rotating sleeve and the inner rotating sleeve are driven to rotate respectively, so that under the cooperation of the driving slider 2 and the driving slider 1, the center mounting seat and the limit block installed on the center mounting seat are driven to move in the direction away from the mounting vertical rod to release the limit of the mounting vertical rod, and the connecting spring is contracted, so that the lateral shear force can be converted into the contraction force of the connecting spring, and after the tractor drives the hydraulic flip plow to turn, the connecting spring stretches and resets, releasing the lateral shear force to drive the C-shaped mounting frame 1, the C-shaped mounting frame 2 and the limit block to reset, thereby realizing the reset of the mounting vertical rod.
