Description

репускное отверстие а открывает выход жидкости в полость В. В этот момент движение поршн  2 прекращаетс  и начинаетс  перемещение поршн  3, которое продолжаетс  до остановки поршн  -гидроцилиндра.The opening opening a opens the exit of fluid into the cavity B. At this moment the movement of the piston 2 stops and the movement of the piston 3 begins, which continues until the piston of the hydraulic cylinder stops.

После прохода преп тстви  под воздействием пружин поршни гидроаккумул тора перегон ют жидкость в гидроцилиндр и возвращают рабочий орган в исходное положение. Скорость срабатывани  предохранительного устройства, а последовательность движени  поршней гидроаккумул тора при .возврате рабочих органов регулируютс  винтом 6 дросселирующего устройства и пружиной обратного кланана.After the passage of the obstacle under the influence of springs, the hydroaccumulator pistons distill the liquid into the hydraulic cylinder and return the working member to its original position. The speed of actuation of the safety device, and the sequence of movement of the pistons of the hydroaccumulator when the working bodies return, is regulated by a screw 6 of the throttling device and a spring of the return clanan.

Формула изобретени Invention Formula Предохранительное устройство к ночвообрабатывающим рабочим органам, шарнирно закрепленное на раме оруди , включающее соединенный с гидравлическим аккумул тором гидроцилиндр, шток которого св зан с рабочим органом, отличающеес  тем, что, сA safety device for night-working tools, hinged on the frame of the gun, including a hydraulic cylinder connected to a hydraulic accumulator, the stem of which is connected to the working body, characterized in that целью Снижени  ударных нагрузок, возникающих нри преодолении преп тстви , и повышени  устойчивости хода рабочих органов, гидравлический аккумул тор выполнен с двум  цилиндрическими полост ми разных диаметров , в которых размещены подпружиненные норшни, причем в иоршне меньшего диаметра имеютс  перенускные отверсти  дл  периодического сообщени  обеих цилиндрических полостей в момент срабатывани  :предохранительного устройства, кроме того полость большего диаметра соединена с гидроцилиндром через обратный клапан, а полость меньшего диаметра - через дроссель.In order to reduce the impact loads arising from overcoming obstacles and increase the stability of the working bodies, the hydraulic accumulator is made with two cylindrical cavities of different diameters in which spring-loaded holes are located, and in the smaller diameter there are transfer holes for periodic communication of both cylindrical cavities at the time of actuation: the safety device, in addition, the cavity of a larger diameter is connected to the hydraulic cylinder through a check valve, and the cavity its diameter - through the throttle.
