Definitions

  • the invention relates to a hopper for storing bulk goods, like dredge goods, which hopper comprises one or more holds, which are provided with discharge means in the form of valves or flaps in the bottom.
  • Such a hopper is generally known, for example from the Netherlands patent application 6404349 laid out to public inspection, which patent application relates to a hopper having valves hinging around longitudinal axes at the height of the bottom surface of the vessel, which valves, when in open position, are swung down and protrude from the bottom of the vessel.
  • the aim of the invention is to provide a hopper, which can also be used in shallow water, but keeps the advantages which are inherent to unloading by means of valves.
  • valves have the property to make quick unloading possible and require relatively little maintenance. They are reliable and the operating mechanism is cheap and rugged.
  • Sliders used in hoppers are known per se, for example from the US patent specification 1,063,284. Sliders, however, have the disadvantage that the construction is more expensive and that when opening, it is required to displace the sliders in guidings and along sealings, while these sliders are pressed against the guidings by the charge resting on it. This results in hard wearing and frequent maintenance.
  • a hopper, which has been provided with sliders at the location of all the discharge openings, is therefore seldom applied because it has little sense to construct a hopper which is only suitable for shallow water and which, during most of the time that it is applied in deeper water, has to deal with the problems which are inherent to the sliders loaded by the charge. Valves do not have these disadvantages for they open up downwards and so are forced open by the charge when unlocking, and move together with the charge in the same direction.
  • the sliders at one or both ends of the hopper hold and of the vessel respectively.
  • the sliders at both ends of the vessel are opened, then this results in an even rising of the vessel in the water and this is sufficient to continue unloading after this via the discharge valves located between the ends.
  • a slanting float-on position can be created through which the possibility comes about to get very close to the coast line.
  • the trim of the loaded vessel can be influenced.
  • the hopper showed in fig. 1 has a hold 2, which is provided in the bottom with two parallel rows of sets of discharge valves 3 and 4 respectively, which are hinged around longitudinal axes and which are kept in the closed position showed in fig. 3 with the help of drawing means 5. In the open state they take the position showed by the interrupted lines in fig. 3.
  • the hold of the hopper is provided at the front with sliders 6 and 7 respectively and at the back with sliders 8 and 9 respectively.
  • the hopper vessel which is showed has four sliders 6, 7, 8 and 9, ten sets of valves 3 on port-side and ten sets of valves 4 on starboard-side.
  • a hopper vessel which is provided in one half with sliders in the bottom and in the other half with valves could be thought of. Such a vessel can approach the coastline closer than a vessel which is exclusively provided with valves and yet is able to discharge the load adequately.
  • a vessel which is exclusively provided with sliders, as known, is able to do this naturally, but, as a matter of fact, then has only sliders with the difficulties attached to it during use in deeper water,
  • valves which are built in higher, like for example known from the already mentioned US patent specification 1,063,284; fig. 2. Putting the discharge valves in a higher location, which valves when open do not protrude under the bottom, has the disadvantage, however, that as a result the total loading volume will be less.
