Description
Technical field
The utility model relates to a kind of coal mining facility, particularly a kind of Height Adjustable carrier bar felling and transporting coal all-in-one of the continuously lateral coal cutting fortune coal advanced for level or nearly level.
Background technology
The continuous coal cutting of side cut fell and transport coal all-in-one solve existing girdle or relatively thin in the critical facility of thick level or flat seam mechanization manless working face, it drives drive chain horizontal cyclic to move by drive sprocket, the mode utilizing the carrier bar connected at drive chain to arrange coal cutting teeth realizes mining, and utilize carrier bar and fuselage to be formed to transport coal crossheading, thus form the all-in-one machine structure felling and transporting coal one, fuselage is used as load bearing component and the guiding parts of carrier bar, fuselage is formed by connecting by multiple case unit, by dumbbell pin connected mode between each case unit, fuselage height and coal mining amplitude correlation, coal mining amplitude sets according to coal seam thickness usually.But existing tax is deposited coal seam thickness and is usually had certain amplitude of variation on bearing, therefore, for the existing all-in-one of take the altitude, can only back production setting thickness coal seam, when squeeze, in the product of coal of back production, spoil composition increases, and affects Coal Quality, when coal seam thickens, coal recovery rate is low.For this reason, need to carry out to felling and transporting coal all-in-one the improvement that adjusts with Coal Seam Thickness Change of height of mining, in requisition for a kind of adapt with it fell and transport coal height and Link plate height is adjustable fells and transports coal carrier bar.
Summary of the invention
The utility model object is to provide a kind of Height Adjustable carrier bar, the fortune coal felling and transporting coal all-in-one of the continuously lateral coal cutting fortune coal advanced for level or nearly level or fortune coal are held concurrently coal cutting, it fells and transports coal height and automatically changes with the distance adjustment between coal-winning machine upper/lower guide, and that mines height for the corresponding adjustment with Coal Seam Thickness Change fells and transports coal all-in-one.
For achieving the above object, the utility model adopts following technical scheme.
A kind of Height Adjustable carrier bar, is driven by haulage chain and is run by guide rail guiding in setting space, and the fortune coal felling and transporting coal all-in-one of the continuously lateral coal cutting fortune coal advanced for level or nearly level or fortune coal are held concurrently coal cutting; Carrier bar forms only retractable telescopic combining structure by carrier bar body and extrusome on Link plate height direction, carrier bar is connected with the haulage chain felling and transporting coal all-in-one by carrier bar body, carrier bar working depth is limited by the distance on fuselage between the upper rail at upper and lower two ends, Link plate height direction and lower guideway, and carrier bar makes its height correspondingly elongate or shorten with the distance change between upper rail and lower guideway by automatic telescopic structure.
Adopt the utility model of preceding solution, carrier bar forms extension type combining structure, and its duty height is corresponding with the distance change between upper rail and lower guideway to be elongated or shortened automatically.For in coal-winning machine, part carrier bar arranges coal cutting teeth, this part carrier bar have coal cutting hold concurrently fortune coal function, by all arranging the mode of coal cutting teeth at carrier bar body and extrusome, can be realized mining the highly respective change with Link plate height change, and the carrier bar only for transporting coal does not need to arrange coal cutting teeth, its fortune coal amplitude also respective change.When coal seam thickness thickening or thinning time, realized the corresponding adjustment of the spacing of upper rail and lower guideway by the mode of adjustment coal-winning machine fuselage height, thus make Link plate height form adaptive accordingly elongating or shortening, thus realize the object of coal mining Height Adjustment.
