Definitions

  • the present invention relates to a ditch cleaning machine arranged on a floating means.
  • a suction dredger-like ditch clearing machine provided with an embankment cutter has already been proposed and arranged so as to be pivotable on all sides on a pontoon-like water craft, the lengthened shaft of same serving at the same time for the driving of the propeller-like embankment cutter.
  • Such an arrangement has the disadvantage that is can only be used on ditches in which the Water craft can float, and furthermore it can only clear out ditches which are wider than the width of the floating pontoon.
  • the centrifugal pump used with same can only act if the whole suction means, in particular, the rather long suc: tion pipe is filled with water. be cleared out, it frequently happens that the cutting device works partly above the surface of the water so that a.
  • the ditch cleaning unit consisting of a cutting head, encased conveying screw and mud centrifugal is arranged on floating means which are adjustable in 'width.
  • the unit is pivotable in vertical and lateral directions.
  • the floating means may be so constructed that at the same time it can be used as a sliding support if in consequence 'of the spatial proportions of a ditch, floating of the arrangement on the water is not possible because of too low a water level in the ditch.
  • the floating means may, for example, consist of two or more floating members, of cylindrical shape connected to each other at an adjustable distance by means of one or several cross bars and may serve as sliding supports when the machine slides on mud.
  • the entire clearing means arrangement including a motor may be suitably balanced and held in equilibrium on a kingpin support.
  • the mud centrifuge, conveying screw and cutting head are arranged on a common shaft.
  • the arrangement may be such that the If shallow ditches are to.
  • Patented Aug. 30, 1960 ice clearing unit can be pivoted out of the middle longitudinal axis of the floating means so that it clears more vigorously on one side of the machine than the other.
  • the height and side adjustment may be effected by means of small hand windlasses.
  • the conveyor screw turning in the suction pipe produces a suction effect at the front end of the pipe and thus sucks the cleared material cut up by the cutting head whereupon the centrifuge arranged on the other end of the screw seizes the material of the ditch pressed into it and discharges it onto the embankment.
  • the floating means may be adapted to the ditch width to be cleared so that the means according to the invention can be used for narrow as well as wide ditches.
  • the forward movement of the whole ditch cleaning machine may be suitably effected by means of a rope.
  • Fig. 1 is a side view, mostly in section, of an embodiment of the present invention
  • Fig. 2 is a plan view
  • FIG. 3 is a cross section on line 3-3 of Fig. 1.
  • Two floating members 1 and 2 of generally cylindricalshape and tapered at the rear end thereof are traversed by cross bars 3, 4 and 5 passing through shackles 3a, Shackles 4a and 5a are secured by threaded bolts 4b and 5b to floating members 1 and 2. Normally,
  • a support 16 is fixedly secured to socket 7 and turns with the same on king pin 6.
  • a yoke 161 is also secured to socket 7 and carries bearings 162 supporting a horizontal shaft 25. Elements 7,16 and 161 constitute a supporting member.
  • Windlass drum 20 on which is wound a rope 21 whose ends are secured to the ends of arms 22 and 23.
  • a turntable crank 19 is connected to Windlass drum 20 for turning the same so that turning of crank handle 19 effects turning of the supporting member 7, 16 and 161.
  • a clearing unit which includes a shaft 8, a bevel gear 9 fixedly connected to shaft 8, a conveyor screw means 11, a cutting head 12, and a mud centrifuge 10 all mounted on shaft 8.
  • the clearing unit further includes a casing 13 for the conveyor screw which is fixedly connected to the housing 13a of the mud centrifuge 10.
  • a bracket including lateral parts 10a and a connecting part 1012 is secured 'to the housing of the mud centrifuge 10 and has bearing means through which shaft 25 passes, so that this bracket with its parts 10a and 10b is turnable with respect to the shaft 25. Consequently, the entire clearing unit is pivotable about a horizontal axis.
  • Elements 7, 161 and 10a, 10b constitute mounting means for mounting the clearing unit on the support 6 for pivotal movement about horizontal and vertical axes.
  • a rope means 18 is secured to the lower end of casing 13 and passes through an intermediate support 18a and over a rope drum 17 which is turnably mounted on a bracket 16a which is part of support 16.
  • Elements 19, 20, 21, 22, 23 constitute first operating means connected to supporting member 7, 161 for turning the same and thereby the clearing unit about a ver- A support, shown to be a king pin 6 is fixedly secured A bracket 26- tical axis defined by the ising pin support 6.
