摘要： Cutter unit equipped with a pump (4) which cutter unit comprises a rotatable cutting device (1) with the help of which underwater soil can be cut wherein the mass that becomes created during the cutting, such as the mass that becomes created from the soil and water moves inside the cutting device (1) and further to the pump (4) with the help of which pump the mentioned mass being in a fluid form is pumped to a suitable location. A cutting/crushing device (2, 8) is adjusted between the cutting device (1) and the pump (4) which cutting/crushing device comprises counter blades (8) and a rotating, double- ended knife edge (2) installed at the front side of these seen from the flow direction of the mass which knife edge is installed in an eccentric way in relation to its axis of rotation.

摘要： A screening device comprising a screen (40) having a first side (43) for presentation to a body of material to be screened and a second side (44). A plurality of elongate screen openings (46) are formed in the screen extending between the first and second sides thereof. A plurality of tines (73) mounted on support means disposed on the second side of the screen. Each tine (73) is movable along a cyclical path at least part of which includes one of the elongate screen openings (46) whereby the tine is receivable in and movable along the elongate screen opening. The tine (73) extends beyond the first side (43) of the screen for at least part of the movement thereof along the screen opening (46). The screening device may be incorporated in various machines including a recovery head for an underground mining apparatus.

摘要： The invention relates to a drag head (1) of a trailing suction hopper dredger. The drag head comprises a visor (2) which is dragged over the bottom and herein loosens soil, and a suction pipe (3) which is connected to the visor (2) and which discharges the loosened soil. The visor (2) comprises at least two individually movable pressure elements (21, 22, 23, 24) transversely of the dragging direction which comprise a number of substantially disc-shaped penetrating bodies (51, 52, 53, 54). The penetrating bodies transmit forces to the bottom via their peripheral edge under the influence of the weight of the pressure element in which they are received, whereby the bottom is broken. The drag head has an improved efficiency.
