Abstract

Sugehode med to innløp eller to sett med innløp (1,2), idet det ene innløp eller sett med innløp (1) er anordnet ved eller nær munnstykkets laveste del og er tilpasset til å suge opp sedimenter fra bunnen sammen med noe vann, mens det andre innløp eller sett med innløp (2) er anordnet i vertikal avstand fra første innløp eller sett med innløp (1) og er tilpasset til kun å suge vann. Sugehodet omfatter et indre rør (3) tilpasset for transport av vann og sedimenter og hvis øvre ende er tilpasset for sammenkobling med en sugeslange av hovedsakelig samme diameter, idet minst nedre del av nevnte indre rør er omgitt av en omsluttende kappe (4) slik at et hovedsakelig ringformet hulrom (5) avgrenses mellom (minst nedre del av) nevnte indre rør (3) og nevnte omsluttende kappe (4), idet minst en åpning som danner innløpet (2) er anordnet ved øvre ende av kappen (4) inn til hulrommet (5), mens innløpet (1) er anordnet ved nedre ende av røret (3) ved at røret helt eller delvis er åpent i sin aksielle retning, idet også kappen (4) nederst er åpen i aksiell forlengelse av røret (3).Suction head with two inlets or two sets of inlets (1,2), one inlet or set of inlets (1) being arranged at or near the lowest part of the nozzle and adapted to suck up sediments from the bottom together with some water, while the second inlet or set of inlets (2) is arranged at a vertical distance from the first inlet or set of inlets (1) and is adapted to suck only water. The suction head comprises an inner tube (3) adapted for transporting water and sediments and the upper end of which is adapted for connection with a suction hose of substantially the same diameter, the at least lower part of said inner tube being surrounded by an enclosing jacket (4) so that a substantially annular cavity (5) is delimited between (at least the lower part of) said inner tube (3) and said enclosing jacket (4), at least one opening forming the inlet (2) being arranged at the upper end of the jacket (4) in to the cavity (5), while the inlet (1) is arranged at the lower end of the pipe (3) in that the pipe is completely or partially open in its axial direction, the casing (4) also being open at the bottom in axial extension of the pipe (3). ).
