The nozzle 7 and the salvaging umbrella 6 are both mounted at the lower side of the front end of the bracket 5. The water spraying end of the nozzle 7 is located above the salvaging umbrella 6. The front end of the bracket 5 is provided with an umbrella control mechanism for controlling the salvaging umbrella 6 to be folded upward, opened, or folded in the opposite direction. The axes of the salvaging umbrella 6 and the hydraulic cylinder 1 are parallel to each other.

[0030] The salvage umbrella 6 includes a sliding rod 601, a sliding sleeve 602, a sliding honeycomb 603, a fixed honeycomb 607, an umbrella mesh 604, a plurality of long umbrella ribs 605 and a plurality of short umbrella ribs 606. The upper end of the sliding rod 601 is vertically connected to the lower front end of the bracket 5, the fixed honeycomb 607 is coaxially connected to the lower end of the sliding rod 601, one end of the short umbrella rib 606 is hinged to the fixed honeycomb 607, and the other end of a short umbrella rib 606 is hinged to the middle part of a long umbrella rib 605.

[0031] In the floating and sinking test of the present invention, the coal loaded into the net bottom bucket 11 is layered up and down in the density liquid into floating materials 12 and sinking materials 13; firstly, the support 5 drives the salvage umbrella 6 in the upward retracted state to move downward and sink into the density liquid through the extension of the hydraulic cylinder 1; secondly, the umbrella control mechanism on the support 5 controls the salvage umbrella 6 to open, at this time, the floating material 12 is located on the umbrella mesh 604, and the support 5 drives the salvage umbrella 6 in the opened state to move upward through the shortening of the hydraulic cylinder 1, and the floating material 12 is picked up during the upward movement of the salvage umbrella 6; then the rotary motor 2 rotates to move the salvage umbrella 6 to the top of the net bottom screen 9, and the umbrella control mechanism controls the salvage umbrella 6 to open and close in the opposite direction, and the floating material 12 on the umbrella mesh 604 falls into the net bottom screen 9 under the action of gravity.
