Field sampling device for searching sediment suspension

The invention discloses a field sampling device for searching sediment suspension. The device comprises a water inlet box, a water outlet box, a hard water pipe, an electric stirrer, a sediment collecting device and a curved sampling pipe, wherein the water inlet box, the hard water pipe and the water outlet box are hermetically connected through a square connecting round pipe; the sediment collecting device is fixedly arranged in the water outlet box; sampling holes are formed in the wall of the box; and the curved sampling pipe is fixedly formed out of each of the sampling holes by virtue of a fixing device. The invention provides the field sampling device for searching sediment suspension. Hydrodynamic conditions at different strengths are generated by adjusting the electric stirrer, sediment under disturbance of a hydrodynamic force suspends, and the rectangular water tank and the hard water tank are maintained on a same horizontal line by virtue of a scaleplate and an iron supporting column, so that the stability of the water flow direction is guaranteed; before a water sample is collected, a rubber check valve seals the sampling holes on two sides of the rectangular water outlet box; the curved sampling tube is inserted into each sampling hole so as to accurately collect the water sample at a certain height in the water tank.
