FIELD: agricultural engineering. ^ SUBSTANCE: safety device has plow beams rotating in vertical plane, hydraulic cylinders coupled through flexible pipes to resilient accumulator, two-link leverage mechanisms pivotally connected to frame and plow beam. Accumulator is provided in hermetically sealed frame cavity charged with working fluid under pressure. Flexible member is located within said cavity. Flexible member is made in the form of hermetically sealed elastic pipe filled with gas under pressure. ^ EFFECT: simplified construction, reduced metal usage and enhanced reliability in operation of accumulator. ^ 4 cl, 3 dwg |
