Definitions

  • the present invention relates to articulated mining machine members with interposed partition, and more particularly to an improvement in a mining planer having a pair of spaced apart base means and corresponding keels provided with an intermediate means interposed longitudinally between the pair of base means and articulatedly interconnecting the base means, whereby to form a pocket preventing excessive entry of extracted mineral into the space between the base members and the keels.
  • Mining machines which include a pair of longitudinally spaced base members articulatedly interconnected and having appropriate keels extending rearwardly under the guide means used with the mining machine, such as a mining conveyor, whereby to achieve reinforced support of the mining machine against tilting which might occur where excessive counter forces are met by the cutting means of the mining machine during extractive engagement with the mine face.
  • a mining conveyor such as a mining conveyor
  • a gap is formed between the pair of base members of the mining machine and in turn the keels attached thereto and underlying the conveyor, together with the bottom edge of the conveyor itself.
  • the fine coal enters this gap into the bottom flight of the conveyor, all to the detriment of the efiiciency of the mining operation.
  • the thickness of the keels is about 50-60 mm. and the conveyor is thus raised about this distance from the mine floor as the keels pass therealong. Since the mining machine is constantly extracting minerahsome of such mineral enters the gap between the keels which is accordingly about 50-60 mm. in height so that the problem in question is constant during the entire mining operation.

  • such improvement comprises intermediate means interposed longitudinally between the pair of base means and articulatedly interconnecting said pair of base means, the intermediate means forming a longitudinal partition between the pair of base means which defines a cushion pocket with the adjacent portion of the mine face between the pair of base means, whereby to accommodate fine particles of mineral which serve as a sealing cushion between such portion of the mine face and the intermediate means thereat to prevent excessive entry of extracted mineral into the space defined between the adjacent portions of the pair of base means, the keels, the underside of such guide means and the mine floor therebeneath.
  • the intermediate means includes an upright wall extending across and occupying the space between the pair of base means as well as a keel. stub, comparatively shorter than the keels and extending substantially in the same direction and plane as said keels and occupying the space between the keels in the vicinity of the'adjacent portion of the guide means at the pair of base means.
  • an upper element may be disposed in the spa-Ce between the corresponding upper portions of the pair of base means, with such element articulatedly interconnecting the pair of base means thereat whereby to define an upwardly limiting cover member above the intermediate means to enhance the prevention of excessive entry of extracted mineral into such defined space.

  • Shown schematically is an upper element 18 which may be provided over the intermediate link 13 to define an upwardly limiting cover member above the intermediate link whereby to enhance the prevention of excessive entry of extracted mineral into the space 12.
  • the disposition of the clearance 7 between the front side 9 of conveyor 3 and the adjacent portion of base means 8 may be appreciated as well as the positioning of the rearwardly extending keel of member 1 under conveyor 3 having the lug 5 at the free end thereof for proper guidance of the mining machine along the conveyor.

  • FIG. 3 the disposition of the sealing pocket 14 is shown between the upright wall 16 of the intermediate link 13 at the front side 9 of conveyor 3 and the mine face.
  • the underside 11 of the conveyor is in engagement with the keel stub 17 which fills the space 12 between the keels 4 and 4' so that none of the fine coal 15 forming a cushion in pocket 14 can enter the space under conveyor 3 to produce the disadvantages noted above in connection with prior art arrangements.
  • the pocket 14 is provided with a fine mineral cushion, generally in the form of fine coal dust where coal is being extracted, such that the underside 11 of the side wall 9' of the conveyor 3' is not disturbed with entry of undesired mineral thereat.
  • a fine mineral cushion generally in the form of fine coal dust where coal is being extracted, such that the underside 11 of the side wall 9' of the conveyor 3' is not disturbed with entry of undesired mineral thereat.
  • This figure also illustrates the preferred similarity in thickness of the keel stub 17 and the appropriate keel (keel 4 being shown schematically), so as to achieve an efficient sealing of the underside 11 of conveyor 3 against entry of unwanted mineral thereat.
  • FIG. 5 shows a prior arrangement in which the link 13 of the invention is omitted from the space 12 so that the gap 10 at the underside of 11' at the front side wall 9' of conveyor 3 may be appreciated.
  • the thickness of keels 4a and 4a attached to the base means 8a and 8a raises the conveyor 3' to form the longitudinal gap 10 between the underside 11 of the conveyor and the mine floor along which the keels and base means slide.
  • the optional upper element 18a is shown which is articulatedly connected at 19 and 19 to the corresponding upper portions of the base means 8a and 8a. Comparing FIG. 5 with FIG.
  • the longitudinal partition between the base line 8a and 8a provided by the link 13 in accordance with the present invention can be appreciated and the manner in which the space 10 is occupied by the keel stub 17 while the space 12 is occupied by the upright wall 16.
  • the cushion pocket provided between the mining machine and the adjacent portion of the mine face advantageously prevents further mineral from passing therethrough to the underside of the conveyor.
  • the construction and arrangement provided in accordance with the present invention has proven better in practice than previous measures utilized such as metal wool, e.g. steel wool inserts, covers, or the like in the area in question.
  • the fine mineral cushion such as fine coal
  • the fine mineral cushion such as fine coal
  • the mining machine especially a mining planer, and constantly renewed, is not subject to wear and is not required to be replaced constantly as was true with metal wool inserts, covers, or the like. Instead, the very operation of the mining machine serves to replace as necessary the fine coal cushion.
  • the collection of fine coal or other mineral beneath the conveyor diminishes abruptly in mining operations, for example, where the construction and arrangement shown in FIG. 5 is provided with the intermediate link of the present invention, for instance shown in FIG. 4.
  • the fine mineral such as coal
  • the gap 10 see FIG. 5
  • the intermediate link 13 may be provided with an elastic apron or the like in place of the upright wall 16 where the upper element 18 is provided thereabove.
  • upper element 18 will protect the intermediate link 13 from direct exposure to impingement of large lumps of mineral, and in such instance a fine coal or other mineral cushion will again collect on the side of such flexible apron adjacent the mine face and remote from the conveyor which will be constantly replenished as the extraction of mineral progresses, yet suitable blockage of the space 12 will exist to avoid the foregoing disadvantages of the prior art.
