Bulldozing pilot valve assembly, bulldozing hydraulic system with bulldozing blade capable of floating and lifting and excavator
The bulldozing pilot valve assembly comprises a valve body, a handle assembly, a first valve part, a second valve part, a third valve part, a first opening, a second opening, a third opening and a fourth opening, wherein the third opening and the fourth opening are used for being connected with the hydraulic control end of a reversing valve. The dozer blade oil cylinder can enter different working states by pressing down the end of the connecting piece of the handle assembly, and the dozer blade ascends or descends or ascends or descends in a floating mode. And when one end of the connecting piece is pressed downwards, the other end of the connecting piece tilts. After the bulldozing blade enters a floating lifting working state, the third valve part can output oil liquid to carry out hydraulic control feedback on the first valve part, so that the first valve part is kept at a first valve position of the first valve part, the second valve part is kept at a second valve position of the second valve part, and the third valve part is kept at a third valve position of the third valve part; therefore, the dozer blade can be effectively maintained in a long-time floating lifting working state.
本发明公开一种推土先导阀组件，包括阀体、手柄组件、第一阀部、第二阀部、第三阀部、第一口、第二口和用于与换向阀的液控端连接的第三口和第四口。通过下压手柄组件的连接件的端部可以使推土铲油缸进入不同工作状态，使推土铲进行上升、下降或浮动升降。且在下压连接件的一端时，连接件的另一端会翘起。在推土铲进入浮动升降工作状态后，第三阀部能够输出油液对第一阀部液控反馈，使第一阀部处于第一阀部第一阀位、第二阀部处于第二阀部第二阀位以及第三阀部处于第三阀部第三阀位的状态维持，从而可以使推土铲能够有效维持在长时间的浮动升降工作状态。
