淘金船是一种进行沙金选取的水上采沙设备。该设备由抽沙系统、选矿系统、尾矿输出系统、供水及矿沙缓冲系统、卷扬系统、龙门架、船体和上部结构及操作室等八个部分组成。淘金船的抽沙系统由管道,冲洗泵,抽砂泵等组成。选矿系统：由圆筒滚动筛,平板振动筛,波动溜槽（粗选设备）,横隔自动洗选机及黄金精选机。
淘金船的尾矿输出系统由管道,沙泵等组成。供水及矿沙缓冲系统：由水泵,水管及缓冲水箱等组成。卷扬系统由大臂提升卷扬机,牵引卷扬机,左右横移卷扬机等组成。挖沙船的龙门架包括槽钢,角铁,滑轮组。船体由平底船组成,用于承载淘金船的各种设备。挖沙船的上部结构及操作室包括主方架,操作室,栏杆,梯,吊架,安装架。
小型淘金船工作原理：由水下冲洗泵将料泛起,然后由抽砂泵将料抽出；经输送管道将料输送至缓冲水箱后,经溜槽流入滚动筛；由筛子侧位冲水管注水将料搅匀；由转筛将小石子分离后经流槽输出；沙子经分流器后均匀通过横隔自动洗选机和黄金精选机选矿,也可用鼓动流槽或淘金毡完成选矿。
对淘金船的保养：当我们在使用淘金船之前首先要检查挖泥船上面螺丝的松紧，定期的加上润滑油。在保障淘金船完成工程的前提下，合理的安排施工时间，要预防管道损坏。在淘金船停止工作时，一定要将淘金船拴牢固，避免被大水冲走。要定期对淘金船的发动机、水泵等重要零件进行检查，防止工作时的突发状况，避免不必要的损失。还要避免淘金船在恶劣天气环境下工作，如大风、暴雨、台风、海啸等。同时要注意保持淘金船工作环境的卫生，不要造成污染。
The gold rush is a kind of water-gathering equipment which carries on the selection of alluvial sand. The equipment consists of eight parts, such as drainage system, beneficiation systems, tailings output system, water supply and sediment buffering system, winch system, gantry, Hull and superstructure and operation room. The drainage system of the Gold rush is composed of pipelines, flushing pumps, sand pumping and so on. Beneficiation system: By cylinder rolling sieve, tablet vibrating screen, fluctuation chute (coarse selection equipment), automatic washing machine and gold selection machine.
The tailings output system of the Gold rush is composed of pipes, sand pumps and so on. Water supply and sediment buffer system: by pumps, water pipes and buffer tanks and so on. The hoisting system consists of lifting hoist, traction hoist, and left-right transverse hoist. The gantry of dredging vessels include slot steel, angle iron, pulley block. The hull consists of a flat bottom vessel used to carry a variety of equipment for the gold Rush ship. The upper structure and operating room of the dredging barge include the main side frame, Operation room, railings, ladder, hanger, mounting rack.
Small Gold rush work principle: by the underwater washing pump will be expected to be thrown, and then pumped by the sand pumping material; After conveying the material to the buffer tank, flow through the chute to the rolling sieve; by the sieve side flush water pipe will stir up the material; by the rotary sieve, the small stones are separated by the flow trough output; The sand passes through the divider after the automatic washing machine and the Gold Select machine, also can agitate flow trough or the gold rush felt to complete the dressing
Maintenance of the Gold Rush ship: When we use the Gold rush before we first check the tightness of the screw dredger above, and periodically add lubricating oil. Under the premise of guaranteeing the completion of the project, reasonable arrangement of construction time, to prevent pipeline damage. When the gold Digger stops working, it is necessary to tie the gold rush to the ship firmly to avoid being washed away by the flood. To regularly inspect the engine, pumps and other important parts of the gold-rush ship to prevent the sudden state of work and avoid unnecessary losses. Also avoid the gold rush to work in harsh weather conditions, such as strong winds, torrential rains, typhoons, tsunamis and so on. At the same time, should pay attention to maintain the work environment hygiene, do not cause pollution.
