The specific embodiment
As shown in Figure 1, a kind of coalpit that is subjected to is disclosed the coal device, originally discloses the coal device and comprises walking mechanism, is provided with the Coal pulling machine structure on the walking mechanism, be provided with to disclose the cleft hand of coal in the Coal pulling machine structure, also be provided with on described walking mechanism or the Coal pulling machine structure and drive the power set that described cleft hand moves to disclose coal.
Be to guarantee dredging efficient and dredging effect, described cleft hand can adopt stainless steel, Yu Shi steel body, signal bronze, needs the hydrochloric acid nickel-base alloy, nickel, titanium or similarly material make.
Preferably, described walking mechanism comprises guide rail 5, pedestal 3, drives the drive unit that direction that pedestal 3 limits along guide rail 5 moves; Described guide rail 5 is set to two, and two guide rail 5 parallel arranging; Described pedestal 3 is slidingly matched with guide rail 5 formations, and perhaps pedestal 3 rolls by roller 4 and guide rail formation and cooperates.
