Изобретение относитс  IK гидроприводам рабочих органов лесозаготовительных машин и может быть использовано в лесной 1промышленности .The invention relates to an IK hydraulic actuator of the working bodies of forest machines and can be used in the forestry industry.

Известны гидроприводы рабочих органов лесозаготовительных машин, включающие насос и два параллельно соединенных гидрораспределител  -дл  подключени  к ним исполнительных гидродвигателей.The hydraulic actuators of the working bodies of logging machines are known, including a pump and two parallel-connected hydraulic distributors — connecting hydraulic actuators to them.

Цель изобретени  - обеспечить (перемещение рабочих органов лесозаготовительной машины 1при различных давлени х.The purpose of the invention is to provide (movement of the working bodies of the logging machine 1 at different pressures.

Достигаетс  это тем, что теред одним из гидрораопределителей установлен редукционный клапан.This is achieved by the fact that a pressure reducing valve is installed by one of the hydraulic determinants.

На чертеже схематически изображен гидропривод рабочих органов лесозаготовительной машины.The drawing shows schematically the hydraulic actuators of the working bodies of a logging machine.

Гидропривод рабочих органов лесозаготовительной машины содержит насос /, гидрораспределители 2 и 3, соединенные с насосом трубопроводами и 5. Трубопроводы б и 7 соедин ют гидрораспределители с исполнительными гидродвигател ми лесозаготовительной машины..The hydraulic actuator of the working bodies of the logging machine contains a pump /, hydraulic distributors 2 and 3 connected to the pump by pipelines and 5. Pipelines b and 7 connect the hydraulic distributors to the executive hydraulic motors of the forest machine.

На трубопроводе 5 установлен редукционный клапан 8, который служит дл  снижени A reduction valve 8 is installed on line 5, which serves to reduce

давлени  ino сравнению с остальной системой в исполнительных гидродвигател х, .подключенных к гидрораопределителю 3.ino pressure compared to the rest of the system in executive hydraulic motors connected to the hydraulic determiner 3.

Работает гидропривод следующим образом.Works hydraulic actuator as follows.

Масло от насоса / поступает одновременно в гидрораспределители 2 и 3. Гп рораспределитель 2 направл ет .по трубопроводам 6 масло К гидроцилиндрам 1под давлением, на которое настроен его предохранительный клапан. Гидроцилиндры, соединенные трубопроводами 7 с гидрораопределителем 3, работают под давлением, отличным от давлени  в гпдрораспределителе 2 за счет установки перед ним редукционного клаоана 8, который снижает рабочее давление.The oil from the pump / flows simultaneously to the hydraulic distributors 2 and 3. The hydraulic distributor 2 directs the oil through the pipelines 6 to the hydraulic cylinders 1 with pressure, to which its relief valve is set. The hydraulic cylinders connected by pipelines 7 to the hydrodistributor 3 operate under a pressure different from the pressure in the hydraulic distributor 2 by installing in front of it a pressure relief valve 8, which reduces the working pressure.

Предмет изобретени Subject invention

Гидропривод рабочих органов лесозаготовительной машины, включающий насос п два параллельно соединенных гидрораопределител  дл  1подключени  к ним исполнительных гидродвигателей, отличающийс  тем, что, с целью обеспечени  перемещени  рабочих органов при различных давлени х, перед одним из гидрораспределителей установлен редукционный клапан.A hydraulic actuator of the working bodies of a logging machine, including a pump and two parallel-connected hydraulic sensors for connecting hydraulic actuators to them, characterized in that, to ensure the movement of the working bodies at different pressures, a reducing valve is installed in front of one of the hydraulic distributors.
