Definitions

  • a transporting wheel is centrally disposed on the device and has radially outwardly extending edges disposed laterally on each side of the wheel which form a channel around the circumference of the wheel.
  • the conveyor belt which is adapted to be received by the radially extending edges of the wheel and is disposed on theexcavating device so as to be guided in the channel, conveys the collected material from the cutting means to the collecting means.
  • This invention relates to underwater excavating devices, and in particular to devices which have a cutting means to cut into the underwater land surfaces, receiving means to collect the excavated material, and means for transporting the excavated material from the cutting means to the receiving means.
  • Excavating devices of this type are known in the prior art and move on a plurality of closely spaced rollers. Between the rollers small cutting knives are arranged for cutting into the land. The excavated material is then transported into a bucket-like drum and to a receiving means which is in the form of a funnel. With this device the size of the material which may be excavated effectively depends on the roller spacing. Fine grained deposits and mud are rinsed away while being transported between the knives and the receiving means and thus cannot be conveyed into the receiving means. This type of device is thus not suitable for scientific, biological or geological testing of an underwater land surface.
  • a further disadvantage of this device is that since a plurality of small openings exist between the fixed and movable parts of the device which operate in close proximity to the underwater bottom, stones may become jammed therein. Only one stone jammed in the machine would cause the device to become inoperative since the rotating drum for transporting the material would not turn. The device would then have to be brought to the water surface. This is rather time consuming and troublesome, particularly at depths of, for example, 4,000 meters.
  • the present invention provides an underwater excavating device which is suitable for collecting both scientific samples and high capacity commercial material from underwater land surfaces.
  • the excavating device is provided with a cutting means and a collecting means which collects the excavated material from the cutting means and transports it to the collecting means.
  • the collected material is transported by a transporting wheel, having radially extending edges, and a conveyor belt.
  • the conveyor belt is mounted so as to enable it to receive material and transport it and is guided by the lateral edges which extend from the transporting wheel.
  • the speed of the conveyor belt preferably corresponds to the circumferential speed of the transporting wheel so that there is a frictionless transportation. This is achieved by coupling the con-.
  • a further embodiment of the invention includes pivotable plates which are mounted on i the conveyor belt to scoop up watery mud into the receiving means without any loss of material.
  • the conveyor belt is provided with openings which permit the undesired mud and clay deposits to be rinsed away from the conveyor channel during the excavating operation.
  • the receiving means is usually formed like a funnel. Means might also be coupled to the receiving means for continuously conveying the collected material to the water surface.
  • the device may also be provided with a plurality of collecting drums when it is used for collecting high capacity material, in order to increase the amount of material to be collected.
  • FIGS. 1 and 2 there are shown two wheels 3 and 4 and a transporting wheel 5., mounted on a common rigid axis 1. Wheels 3 and 4 are provided with ribs 2. Axis I is mounted in a frame which supports wheels 3 and 4 and consists of a collecting drum 6 at into rear end of the device, a roller bar 7, rods 8 and runners 9 shown in FIG. 2 which are mounted in front of the device for stabilizing the machine.
  • a pulling axle l0 is connected to the frame and is rotatably mounted around a horizontal axis 11.
  • a rope or other suitable means may be attached to the end of the axle 10 in order to move the device.
  • the laterally disposed outer edges 12 and 13 extend radially outward from transporting wheel 5.
  • a cutting knife 15 is disposed between the edges 12 and 13 to cut into the land surface 14.
  • a conveyor belt 16 is provided adjacent to transporting wheel 5.
  • the collected material is conveyed on this conveyor belt from knife 15 to collecting drum 6.
  • the conveyor belt is guided between radial edges 12 and 13 of transporting wheel 5, and isforced against the wheel 5 between the radial edges as a result of radially inwardly directed tension produced by the conveyor belt mounting structure.
  • the conveyor belt engages the wheel as the material is conveyed upwardly from knife 15.
  • a sheet metal chute 17 is provided to guide the collected material in the direction of arrow 18 and into collecting drums 6,
  • the excavating device also includes rods 21 upon which knife is mounted. Rods 21 are mounted on roller bar 7 and are rotatable about a horizontal axis 20. Rods 21 are also coupled to rigid axis 1 by rods which are pivotably connected to rods 21 on axis 26. This coupling to the axis 1 allows rods 21 to be pivoted and thereby allow height-wise adjustment of knife 15 and also an adjustment of the channel space existing between conveyor belt 16 and transporting wheel 5.
  • conveyor belt 16 is provided with ribs 22 which engage corresponding cutouts 23 which are provided in transporting wheel 5.
  • Conveyor belt 16 thereby moves with the same speed as the outer edge of transporting wheel 5.
  • Conveyor belt 16 is also provided with pivotable plates 24 which assist in the excavation of the material.
  • the transport wheel and the conveyor belt may be provided with a plurality of openings 27. These openings permit excavated material which is undesirable to be rinsed away during the excavating operation so that only the desired material is collected in the collecting drums.
  • An underwater excavating device having a cutting means to cut into land surfaces underwater, a collecting means for collecting the excavated material, and conveying means for conveying the collected material from the cutting means to the collecting means, the improvements comprising:
  • a transporting wheel centrally disposed on the device, having radially outwardly extending edges disposed laterally on either side of said wheel, forming a channel around the circumference of said wheel, and a plurality of cut-outs disposed in said radially outwardly extending edges;
  • a conveyor belt disposed between said radially outwardly extending edges of said wheel so as to be guided in said channel formed by said radially outwardly extending edges, for conveying the material collected from the cutting means to the collecting means, and including a plurality of rib members which extend laterally beyond the edges of said conveyor belt so as to engage said cut-outs provided in said radially outwardly extending edges of said wheel, said cutouts and said rib members cooperating so that the speed of said conveyor belt corresponds to the peripheral speed of said transporting wheel.
  • said conveyor belt further comprises pivotable plates mounted across the width of said conveyor belt, for conveying the excavated material from the cutting means to the collecting means.
