Description

A kind of Height Adjustable coal-winning machine case unit
Technical field
The present invention relates to a kind of coal mining facility, particularly a kind of continuously lateral coal cutting promoted for level or nearly level Transport the Height Adjustable coal-winning machine case unit for felling and transporting coal all-in-one of coal.
Background technology
It is to solve existing girdle or relatively thin middle thick level or nearly water that the continuous coal cutting of lateral incision formula, which fells and transports coal all-in-one, The critical facility of level coal mechanization manless working face, it drives drive chain horizontal cyclic to move by drive sprocket, using in drive The carrier bar of dynamic chain connection sets the mode of coal cutting teeth to realize coal mining, and using carrier bar and fuselage formation fortune coal crossheading, so as to be formed The all-in-one machine structure of coal one is felled and transported, fuselage is used as the load bearing component and guiding parts of carrier bar, and fuselage is connected by multiple case units Connect and form, connected between each case unit by Push-fit, fuselage height and coal mining amplitude correlation, coal mining amplitude Generally according to coal seam thickness setting.But existing preservation coal seam thickness generally has certain amplitude of variation on bearing, because This, for the existing all-in-one for determining height, can only back production set the coal seam of thickness, when squeeze, the production of the coal of back production Spoil composition increases in product, influences Coal Quality, when coal seam is thickened, coal recovery rate is low.For this reason, it may be necessary to felling and transporting coal one Machine carries out the improvement highly adjusted with Coal Seam Thickness Change of mining, in requisition for a kind of height-adjustable being adapted therewith Fell and transport coal case unit.
The content of the invention
It is an object of the present invention to provide a kind of Height Adjustable coal-winning machine case unit, adopting for coal is transported for continuously lateral coal cutting Coal all-in-one is transported, by the way that its height is arranged into the telescopic combining structure of height-adjustable, to realize the machine for felling and transporting coal all-in-one Height degree adjustment requirement, reaches that fell and transport coal all-in-one does not reduce coal quality and the rate of extraction because of Coal Seam Thickness Change.
To achieve the above object, the present invention is adopted the following technical scheme that.
A kind of Height Adjustable coal-winning machine case unit, coal all-in-one is felled and transported for what continuously lateral coal cutting transported coal, including Horizontally disposed base plate and top board, base plate and top board connect into I-shaped frame by wallboard;The wallboard by wallboard body and Extrusome is upwardly formed only telescopic combining structure in wall-plate level side, and wallboard body is fixedly connected on the base plate, stretched Contracting body is connected on the top board, and hydraulic lifting device is provided between extrusome and wallboard body.
Using the present invention of preceding solution, because the height of case unit is in telescopic adjustable structure, thus The coal all-in-one fuselage height that fells and transports of composition is in accordingly adjustable structure.During coal-winning machine coal mining, Coal Seam Thickness Change is met When, can be by adjusting fuselage highly, and the carrier bar length with coal cutting teeth is accordingly adjusted, coal cutting amplitude is formed correspondence adjustment. Such as when coal seam thickness is thickening or thinning, case unit extrusome is raised or declined adjustment, coal cutting carrier bar accordingly elongation or Shorten, make the corresponding increase of coal mining height or reduce, so as to adapt to Coal Seam Thickness Change and ensure the mesh of the rate of extraction and coal quality 's.
It is preferred that, the only telescopic combining structure is slidably matched by rectangle grafting fit structure to be formed.Wallboard body The only telescopic annexation of characteristic formation circumferentially rotated is reliably limited using rectangle grafting fit structure between extrusome, It can utilize the bonding strength of panel cross section shape raising therebetween to greatest extent.
