摘要： An excavation head, mounted on one end of a telescoping hollow boom, has nozzles for directing jets of high speed air at an excavation face to loosen soil. A vacuum transport pipe extends from the excavation head through the hollow of the boom to a spherical joint. The spherical joint movably joins the other end of the boom to a primary separator. The primary separator is a chamber for disentraining loosened soil from air flowing through the primary separator. A primary air lock is fixed to the lower portion of the primary separator for expelling soil from the primary separator. A secondary separator is joined to the primary separator by way of a separator connector pipe. A secondary air lock is fixed to the lower portion of the secondary separator for expelling soil from the secondary separator. A positive displacement vacuum pump has its vacuum side pneumatically connected to the secondary separator. A conveyor is located under both the primary air lock and the secondary air lock to receive soil that is expelled by these air locks. Hydraulic actuators lift, swing, and extend the boom such that the excavation head is positioned on the excavation face.
摘要翻译：安装在伸缩式空心吊杆一端的挖掘头具有用于在挖掘面处引导高速空气的喷嘴的喷嘴，以松开土壤。真空输送管从挖掘头通过悬臂的中空部延伸到球形接头。球形接头将动臂的另一端可移动地连接到主分离器。主分离器是用于使流过主分离器的空气中的松散土壤脱离的室。一次空气锁固定在主分离器的下部，以从主分离器排出污垢。二次分离器通过分离器连接管连接到主分离器。二次气闸固定在次级分离器的下部，用于从次级分离器排出污垢。正排量真空泵的真空侧气动连接到二次分离器。输送机位于主气锁和二次气锁两侧，以接收被这些气闸排出的土壤。液压执行机构提升，摆动和伸展吊杆，使得挖掘头位于挖掘面上。

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 method of recovering mineral nodules deposited on the ocean floor which comprises the steps of pumping a continuous flow of ocean water along a first confined path through an exchange position within the vicinity of the ocean floor where the mineral nodules to be recovered are deposited from an ocean water inlet position out of the aforesaid ocean vicinity and then upwardly to a discharge position on a surface vessel, confining ocean water within a second path within the aforesaid ocean vicinity, continuously flowing ocean water in the second path by pumping the same at a pumping position spaced down-stream from an exchange position therein, continuously moving from the ocean floor to a separating position within the aforesaid ocean vicinity a mixture containing deposited mineral nodules and smaller particles forming a part of the ocean floor on which the mineral nodules were deposited, continuously separating the mixture at the separating position so as to obtain a supply of separated mineral nodules within ocean water, continuously feeding the supply of separated mineral nodules to the second path at a feeding position upstream from the exchange position therein, and continuously exchanging between the exchange positions within the first and second paths successive incremental volumes of ocean water and mineral nodules from the second path to the first path with comparable successive incremental volumes of ocean water from the first path to the second path.

摘要： A nodule collector for deep sea mining includes an outer sledge and an inner sledge disposed in and connected to the outer sledge for trailing movement therewith. The inner sledge is provided with a transversely extending cutting blade, a plurality of jet nozzles arranged along the cutting blade, and a longitudinally oriented duct. When the collector travels across the seafloor, the cutting blade cuts into the seafloor and raises it thereover. The water jets from the nozzles impinge upon the summit of the raised seafloor material so that nodules and sediments at the summit are carried away by the water jets and introduced through the duct into a collecting chamber provided in the outer sledge. The collecting chamber has a special design to prevent entrance of undesirably large sized nodules thereinto and residence of undesirably small sized nodules and sediments therein. The nodules collected in the collecting chamber are successively transported up to the mining ship for recovery.

摘要： A dredging system operates entirely by siphon action and includes a completely sealed conduit system having the intake end disposed upstream or at an upper level from the outlet end which is disposed sufficiently below the inlet end to maintain a flow of water once started. A pump and bypass system is provided for starting the system in operation with the pump bypassed once the system begins this operation. The system is designed to operate continuously without the need for auxiliary power at dams and reservoirs and the like.

摘要： A combination excavator and conveyor which employs high-power sonic energy to loosen and fluidize the earthen material which is to be removed from the excavating area. Gyrating or orbital-mass sonic oscillators impart resonant standing waves to the earth cutting portion of the excavator as well as to the conveyor which carries the excavated material to a discharge location. Selfpropelled and towed versions are shown. Also illustrated is an integral excavating-conveying device in which the toothed end of a sonically excited conduit is used to ''''nibble'''' the earthen surface and thereafter fluidize and propel the loosened material through the sonically vibrated conduit to a discharge location.
