Definitions

  • the invention relates to a vessel comprising a hold for bulk material and an unloading device.
  • a vessel is disclosed in GB-A-19 425 - A.D. 1909 and in DE-A-2 144 865.
  • the invention provides a vessel of the type mentioned in the preamble which has the feature that the unloading device comprises a chassis movable in lengthwise direction of the hold and guided by means of rails, which chassis bears via hoisting means a grab which has a length which is greater than half the breadth of the hold.
  • the cargo can be removed per layer in parallel bites.
  • the following layer then presents itself as uniform, parallel transverse waves which allow of easy taking up by the grab. This manner of unloading furthermore lends itself well to an automatic process because of the regular presentation of material.
  • the invention also relates to and provides a method as formulated in claim 8.
  • the vessel 1 comprises a hold 2 for receiving bulk material 3, in particular gravel, although sand, coal, grain and other bulk materials are also conceivable.
  • the vessel 1 has an unloading device 4 comprising a chassis 5 which is guided along rails 6 in lengthwise direction of the hold 2.
  • the wheels 7 are driven by electromotors or hydromotors (not drawn).
  • a hoisting frame 8 is connected pivotally to the chassis 5 about a horizontal axis 9 and is swivelled with hydraulic cylinders 10 between a grabbing position drawn in fig. 3 with full lines and a release position drawn in fig. 3 with dashed lines.
  • the grab 15 has a length k which is greater than half the breadth 1/2 b of the hold 2.
  • k is greater than 1/2 b , preferably greater than 3/4 b and for example at least 6/7 b .
  • the grab 15 is located above receiving means 16 arranged on the chassis 5 consisting of an elongate trough 17 positioned transversely to the hold 2 which debouches onto a cross conveyor 18 which discharges the material via a discharge chute 19 onto a lengthwise conveyor 20 disposed alongside the hold.
  • this discharge conveyor 21 is swivelled on board about a shaft 23 into the position drawn in fig. 1 with dashed lines and then rests on a support 24.
  • An upper beam 25 of the grab 15 bears a number of ultrasonic pick-ups 26 which signal when the distance of the opened grab 15 to the material 3 has reached a certain minimum distance.
  • the grab 15 is suspended on four cables 14 arranged at a considerable mutual distance the grab 15 remains properly positioned in transverse direction of the hold 2.
  • the material 3 is picked up from the hold 2 in layers wherein an elongate bite 28 extending in a transverse direction is picked up each time, which bite has a part cylinder-shaped bottom surface 29 and two part cylinder-shaped upper surfaces 30.
  • the grab 15 has a well-presented bite to handle with each following layer because the chassis 5, and therewith the biting grab 15, is disposed each time staggered a half bite 28 relative to the previous layer.
  • the unloading method controlled by a computer, is carried out automatically.
  • the chassis 5 is hereby displaced each time a bite breadth c after each bite 28 and in each case only one bite 28 is taken up and unloaded above the receiving means 16. After taking the bite 28, during the raising thereof and during the swivelling of the hoisting frame 8, the chassis 8 is already being moved a step in the length of the bite breadth c so that the opened grab 15 immediately comes to lie at the correct position for the following bite 28.
  • the reciprocal swivelling of the hoisting frame 8 also takes place automatically. Paying out of the closing and hoisting cables is stopped at the correct moment by the ultrasonic pick-ups 26. The end of the layer is signalled by limit switches (not drawn) on the chassis when the head end walls 38 of the hold 2 are approached.
  • the chassis 5 is displaced a half bite breadth c back at the first bite 28 from a following layer.
