Design Rocker hydraulic clearance machine
[Summary] : Now, with the increasing degree of mechanization of coal mining, underground coal bunker storage capacity is also growing, but also to the bunker along with clean-up work to bring difficult. Therefore, the study of the underground bunker cleaning method is very meaningful. The design of the arm hydraulic clearing machine, the purpose of cleaning up coal bunker makes more efficient mechanization. .The design of most of the system uses a hydraulic drive way to achieve body movements, using hydraulic transmission because the hydraulic drive to meet the power source, the actuator is separated, so that the whole mechanism of action more coherent and stable. Further hydraulic stepless speed can also be achieved as well as the requirements of the remote control, light weight, small size,
smooth transmission is one of the important reasons for the use of a hydraulic drive in this design. Underground complex situation because of the restrictions by the most important design principle is to achieve the hydraulic oil in the loop security control to ensure protection of process equipment operator safety. Bunker is consistent with safety requirements to clean up.
