Telescopic boom loader
The invention relates to a telescopic boom loader, and aims to solve the problem that an oil supplementing oil cylinder is impacted by high-pressure oil when an existing telescopic boom loader carries out a bucket retracting action. The invention provides a telescopic boom loader, which comprises an oil supplementing control valve which is connected with a large cavity and a small cavity of an oil supplementing oil cylinder and a large cavity and a small cavity of a rotating bucket oil cylinder through pipelines, and a reversing control end of the oil supplementing control valve is connected with a movable arm control device; the movable arm control device is provided with a large cavity and a small cavity of a oil recharging oil cylinder which are correspondingly communicated with the large cavity and the small cavity of the rotating bucket oil cylinder through the oil recharging control valve when the movable arm is operated, and the oil recharging oil cylinder and the rotating bucket oil cylinder are mutually cut off when the movable arm control device is not operated. According to the invention, the oil supplementing oil cylinder is communicated with the rotating bucket oil cylinder to realize the posture adjustment of the bucket only during the lifting operation of an actuating arm, and the oil supplementing oil cylinder and the rotating bucket oil cylinder are mutually cut off during the rotating bucket operation, so that the rotating bucket operation does not influence the oil supplementing oil cylinder, and the corresponding adverse effect is avoided.
本发明涉及伸缩臂装载机，为解决现有伸缩臂装载机进行收斗动作时补油油缸受高压油冲击的问题问题；提供一种伸缩臂装载机，其包括补油控制阀，所述通过管路与补油油缸和转斗油缸的大腔和小腔连接且换向控制端与动臂控制装置连接，所述动臂控制装置具有动臂操作动作时补油油缸的大腔和小腔经补油控制阀对应与转斗油缸的大腔和小腔连通，所述动臂控制装置没有动臂操作动作时补油油缸与转斗油缸之间相互截止。本发明仅在作动臂升降操作时，补油油缸与转斗油缸连通，实现铲斗姿态调整，而在转斗操作时，补油油缸与转斗油缸相互截止，所进行的转斗操作不会对补油油缸产生影响，由此避免相应的不利影响。
