US Patent:

46469060, Mar 3, 1987

Filed:

Apr 21, 1986

Appl. No.:

6/857393

Inventors:

Arnold G. Wilcox - Shady Spring WV
Gopal Shah - Beckley WV

Assignee:

Fairchild Incorporated - Beckley WV

International Classification:

B65G 6502

US Classification:

198303

Abstract:

Apparatus for use in conveying coal from the conveyor of a continuous miner to a spaced floor conveyor comprising first, second and third cooperating elongated scraper conveyor assemblies each having a coal receiving end and a coal discharging end. The receiving end of said first conveying assembly has a connection with the miner providing for limited tilting movement and for generally horizontal swinging movement with respect thereto in a position to receive the coal discharging from the conveyor of the miner. First and second mounting members extend in cantilever fashion from the receiving end of the second conveyor assembly and the receiving end of the third conveyor assembly respectively. First and second crawler units are disposed below the first and second mounting members respectively. Each crawler unit includes a frame structure, a pair of longitudinally coextensive parallel power driven endless track assemblies connected with the frame structure and a connection for supporting the associated mounting member on the frame structure for limited tilting movement and for horizontal swinging movement about a vertical axis disposed between the associated pair of endless track assemblies and intermediate the longitudinal extent thereof.

US Classification:

299 64

Abstract:

A continuous mining machine comprising an elongated conveyor assembly for continuously conveying coal cut from a coal seam rearwardly away from the face of the coal seam being cut having a frame structure associated therewith. A power driven cutting assembly is disposed forwardly with respect to the frame structure for cutting coal from the coal seam for conveyance rearwardly by the conveyor assembly. A pair of power driven endless track units is provided for mounting the cutting and conveyor assemblies for movement between a tramming position wherein the assemblies are supported on power driven endless track units in a generally balanced condition for transport within the mine and an operative cutting position wherein the assemblies are moved forwardly in a generally unbalanced condition. Vertically extensible and retractable jacks are carried by the power driven endless track units for extension into mine roof engagement so as to stabilize the units when the cutting assemblies are moved from the tramming position into the operative cutting position. Power operated units are provided for moving the assemblies from the tramming position into the operative cutting position while the vertically extensible and retractable means is extended into mine roof engagement.
