Hydraulic digging arm for mining
It was developed for bad working conditions where workers need the hydraulic digging equipment which could rotate big angle with long arms.
This equipment was fully controlled by hydraulic with the advantages of compact structure, and small size, which could save energy, be easily controlled and produce less pollution, at the same time achieve the all kinds of mechanized duties under the mine and increase efficiency.
Hydraulic digging arm contains scraper pan, pan arm, vice arm, arm, rotating seat, reversal seat, underpan, walking areas, and hydraulic control system.
After getting to the face by trance flat car, the hydraulic control system offers the energy to the vice arm.
Then the vice arm offers the energy to the pan arm, which connects the scraper pan to excavate
The rotating seat could rotate to left or right from the hydraulic cylinder.
The reversal seat could reverse a maximum of 70 degrees and connect the scraper pan, pan arm, vice arm, arm making the function of full cleaning achieved.
When the driving machine needs to walk, walking machine will stretch four lifting cylinders out, and lift the slider brace, drive the cylinder, drive the body forward or back, and the maximum of each step is 650mm, helping to achieve walking or moving.
