摘要： There is provided a dredge vehicle supporting a dredge assembly for collecting ore particles from the ocean floor. The dredge assembly includes several nozzles extending forwardly of the supports for the vehicle, pump means for developing a suction flow into and through the nozzles and a screen to separate the ore particles from most of the water before feeding the ore into, e.g., an airlift system leading to a surface vessel. Preferably, an intake of clear water from above the vehicle is used to carry the ore to and up the airlift system.Advantageously, the water flows straight through the system and exhausts from the rear of the vehicle, and mud is cleared from the ore before bringing the ore to the surface.

摘要： A dredge unit having a buoyant support carrying a sluice box suspended beneath, a water suction system connected to an outlet end on the box and a suction hose operatively connected to an inlet end thereof. The water suction system operates to draw water and material through the suction hose and into the sluice box where material of relatively high specific gravity is contained while the remainder and the water is discharged from the system.

摘要： A cutterhead for dredging water-bed material from a body of water. The cutterhead comprises a shroud presenting a front margin for receiving water-bed material into an interior space of the shroud. The shroud additionally includes a port from which water-bed material can be removed from the interior space of the shroud. The cutterhead additionally comprises a rotatable cutterbar at least partially received within the interior space of the shroud. The cutterhead further comprises a debris guard positioned between the cutterbar and the port. The debris guard is operable to filter the water-bed material removed from the shroud through the port. At least a portion of the debris guard that faces the cutterbar includes a concave shape.

摘要： A compact mobile vacuum boring, and excavation method comprising a device which will create a vacuum condition within a vacuum container and having a vacuum conduit to air convey a liquid and or solid particles into the vacuum container. The vacuum container air inlet & outlet conduit arrangement may also facilitate the separation of solids from the vacuumed air flow by producing a cyclone effect within the vacuum container. A circular cyclone effect is created within the vacuum container by the arrangement relationship between the inlet and outlet vacuum air conduits and baffles. As the air velocity slows, the solids precipitate out of the air and settle in the vacuum container. A housing with filters disposed within it is also adjacently mounted near the vacuum container in order to reduce the quantity of connecting conduits and facilitate a compact, efficient and clean interaction between the vacuum container and the filter housing. The vacuum container access door and the filter housing access door may be adjacently placed in near proximity to each other for user friendly access to empty and clean the vacuum container and filter house or a common door may access both. A compressible seal and conduit arrangement may be used as a quick disconnect between the vacuum producing means and the filter housing. A reversing valve arrangement may be used to back flow air through the filter. Sensors, data gathering, data logging and documentation of a service event may be included. The above systems may be mounted on a variety of mobile platforms.

摘要： A placer gold separating method includes subjecting placer gold-and gold ore-containing sand and gravel layers accumulated on the bottom of the water of a river and placer gold- and gold ore-containing sand and gravel layers formed deep in the ground to excavation or suction excavation by utilizing a water pressure difference. This causes a mixture of the excavated or suction excavation placer gold- and gold ore-containing sand, gravel and water to flow horizontally by the action of a pressure fluid. The placer gold and gold ores are separated by utilizing a specific gravity difference while the mixture is flowing. A placer gold mining boat used to practice this method is provided thereon with a combination of a suction excavation component, a mixture transfer component, a component for separating placer gold by utilizing a specific gravity difference, and a component for discarding the remaining mixture from which the placer gold has been separated. A placer gold separating method is characterized by causing a mixture of placer gold and gold ores or pulverized gold ores and water to flow in a metallic cylinder. A magnetic field is generated by a magnetic field generating component provided on an outer circumferential surface of the metallic cylinder, and the placer gold in the mixture is magnetically deposited on the inner surface of the metallic cylinder, whereby the placer gold is separated.
