摘要： An apparatus for dredging using a pump which forms a highly pressurized, rotating stream of liquid which is directed down the inlet conduit to a discharge and the momentum and energy of the rotating stream is transferred to the solids and liquids, suspending the solids to agitate and separate the same to make the solids more easily suspended. The agitated solids and liquids flow upwardly in a counter-flowing outer annular stream around the downward flowing, rotating stream. The pump is very lightweight as compared to conventional centrifugal dredging pumps and is operated at high speeds, for examble 1,000-2,000 rpm to eliminate the usual speed reducers to prevent cavitation when using the centrifugal pumps.

摘要： A method and apparatus for efficiently and economically hydraulically dredging to a level bottom. The method includes the use of a cutter head which is pivotally mounted to the end of a dredging ladder. The cutter head is swung through its cutting arcs with the axis of rotation of the cutter head aligned with the longitudinal axis of the ladder. The cutter head is tilted relative to the longitudinal axis of the ladder until the cutter blades are parallel to the level bottom to be cut with the adjustment accomplished before the cutter head is swung through the last cutting arc above the level bottom to be reached. The apparatus includes a pivotal connection between the cutter head and the ladder which is located at the trailing edges of the cutter blades so as to follow the path of the trailing edge of the swath of the normal cut of the cutter head.

摘要： In a tunnel driving apparatus, and particularly such apparatus where a work face is supported by fluid, a cutting appliance is employed which is composed of a swinging arm carrying a cutter head. The arm can range over the face to detach material therefrom with the cutter head. Means for driving the cutter head is accommodated entirely within the arm itself and a conduit or the like extends through the arm and serves optionally to remove debris by suction or to convey pressure fluid to the face to assist the cutter head.

摘要： The rotatable cutter head of a suction dredge which is of rearwardly-divergent spiral toothed-rib construction has a crusher of open-work construction fixedly mounted therewithin and cooperating therewith to crush and reduce the size of hard lumps dug by the head to reduce damage to and clogging of the suction and discharge lines and the dredge pump. Preferably, the crusher is a frusto-conical grid having a flat sector which further cooperates with inner surface portions on the cutter head ribs that incline inwardly from the leading to the trailing edges of such portions.

摘要： A liquid inlet adapted to fit over the intake end of a suction hose for a portable dredging machine. The inlet is elbow shaped, having a discharge end mountable to the dredging machine suction hose. The opposite end of the inlet includes a set of spiral-shaped fingers that are powered to rotate in front of an open intake end. The fingers are rotated by a hand-held drive motor on a shaft that passes through a portion of the elbow. The rotating fingers strain material drawn into the elbow and suction hose and deflect material that could otherwise clog the suction hose.
