Definitions

  • the invention refers to a reclaiming and-excavating appliance, e. g. bucket dredger, the
  • an excavating member which loads out sideways, is rotative' at the front end of a backbone which is mountedon a bogie so that it can either be raised or lowered or swung in a horizontal plane.
  • the excavating member consists of a number of scoops which converge at the front'end, and are joined in/a common. ring .at the rear end, which ring is rotated by a driving motor. It. is of advantage 'to mount the driving motor at the end of the backbone which is opposite the excavating member.
  • the transmission from motor to member may be made by a shaft and pinion.
  • The'backbone is preferably of tubular shape and inside thereof a conveying medium is suitably driven by a special drive which is controlled independently of the movements of the excavating member.
  • the conveying medium can be constructed as a belt conveyor.
  • the backbone will be of rather short construction. Therefore a trough-shaped ,belt conveyor cannot be readily suspended, and it will be of advantage to use belt conveyors to in two parts namely a stationary and a rotating part, the stationary part being interrupted at the delivery point of the material and being bent down to the conveying medium, e. g. a belt conveyor, by means of side sheets.
  • the conveyor is preferably extended into the excavating member.
  • the shovels or scoops of the excavating member can be constructed so as to protrude over the front end of the backbone in order to facili- I tate work in front of the member. Itis suitable to enlarge the shovel or scoop in cross-section from the front to the back so that any jammed tube. In the second case it is impossible to excamaterial which would not fall onto the conveying medium is loosened up in travelling back and drops down.
  • the cuttingblades of the excavating member might also be helically disposed and it is of advantage that the pitch of the helix increase from head to tail. This construction is best adapted to excavate broken stone. In this.
  • scoops might be used, which do not converge into one point at the front end and are afllxed to a ring at'the rear only. Where a stack of material requires an excavation in different directions it is of advantage, to use. twin scoops. joined at their backs. In this case the twin scoops might have a hinged arrangement so that those of the scoops protrude which are facing in the working direction.
  • the invention further provides that the back- Lbone be raised or lowered and swung in a hori- ,zontal direction at or about the point where the which the rims are vulcanized, This allows also a deep dipping of the backbone as such belt conveyors allow steeper gradients than flat or trough-shaped belt conveyors.
  • a trolley motor willbe the best drive for the belt conveyor.
  • backbone can be of telescopic construction
  • the belt -conveyor can be adapted in its interior material is delivered to some other means of transport, e. g. a jib or a portable belt conveyor or the like.
  • the invention also provides for a control of the elevation and side movements by two independent motors, e g. electrical motors. caterpillars which carry the appliance are preferably also driven by two independent motors. Where no electric power is available it is of advantage to connect or couple the appliance with an engine-driven electric generator, which provides, in addition to a source of light, a readily controlled supply of power for further conveying means e. g. portable belt conveyors or the like which are toconnect with a unit of this invention.

  • an engine-driven electric generator which provides, in addition to a source of light, a readily controlled supply of power for further conveying means e. g. portable belt conveyors or the like which are toconnect with a unit of this invention.
  • the tubular backbone can be equipped with doors which allow an easy cleaning and lubrication of the idlers, etc. It is best to makearrangements that the conveying maximiii'is suspended in the tubular backbone in such fashion that it can be removed and replaced at will.
  • the appliance ma find use in driving shafts of any kind and cross-s tion, as also for dumpviews, viz:
  • the appliance can also be used with advantage for digging trenches and saps, etc., for military purposes. Contrary to devices of the prior art, it allows the digging of trenches of any cross-section and at sharp curvatures with sudden enlargements and narrowings.

  • Platform 40 is movable around a vertical axis at 39, in a horizontal plane on circular track 5 of said base.
  • the backbone is fulcrumed at M upon platform 40, and elevated and lowered by means of spindles and nutson the two pillars 6 and I.
  • the motor 8 serves for the movements in a horizontal plane, and the motor 9 for the elevating and
  • the tubular backbone 4 carries in its interior a conveying medium which is shown in the drawing as a belt conveyor, III which is driven by the trolley motor ll; the excavated material is delivered at point l2.
  • a conveying medium which is shown in the drawing as a belt conveyor, III which is driven by the trolley motor ll; the excavated material is delivered at point l2.
  • the excavating member l3 consists of a stationary part l4, which appears as an extensio'n of backbone 4, and the rotating shovels or buckets IS.
  • the feed chute I6 is formed by skirts or flaps bent down and in from stationary part I I, and acts also as wearing sheets.

  • Thetubular backbone 4 is equipped with flaps 'or doors 25 and 26, which allow easy accessfor lubrication and adjustment of the idlers of the belt conveyor.
  • the whole belt conveyor unit is suspended in the tubular backbone so that it can be easily taken out and replaced.
