Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

1-4, a river bottom mud sampling device includes a base 1 on which a support rod 11 is installed, and a first take-up wheel 2 and a second take-up wheel 20 are symmetrically installed on the outer wall of the support rod 11 , a sleeve 12 is installed on the top of the support rod 11 , and a telescopic rod 3 is inserted into the sleeve 12 . A limit ring 32 made of rubber material is sleeved on the outer wall of the telescopic rod member 3 . The arrangement of the limit ring 32 can effectively prevent the telescopic rod 3 from sliding in the direction of the dredging device 4 in the sleeve 12 under the pulling force of the dredging device 4 .

A first pulley 31 and a second pulley 310 are symmetrically installed at the projecting end of the telescopic rod 3 , and a dredging device 4 is arranged below the first pulley 31 . The dredging device 4 includes a mounting plate 41 , and the wire group on the first wire take-up pulley 2 bypasses the first pulley 31 and is connected to the mounting plate 41 . The installation plate 41 is fixedly plugged with a tube 42 , the bottom port of the tube 42 is plugged with an inverted funnel-shaped dredging pipe 43 . A piston 44 is arranged above the dredging pipe 43 , a push rod 45 is connected to the piston 44 , and the wire group on the second wire take-up wheel 20 bypasses the second pulley 310 and is connected to the push rod 45 . The four corners of the bottom plate of the base 1 and the mounting plate 41 are provided with ground insertion rods 13 .

When in use, transport the disassembled device to the working point, assemble the device first, and insert the ground rod 13 on the base 1 tightly into the ground to ensure that the top plate of the base 1 is flush with the ground, and then Insert the telescopic rod 3 into the sleeve 12, put the upper limit ring 32 on the outer wall of the rear end of the telescopic rod 3, and then pass the wire set on the first wire take-up pulley 2 around the first pulley 31 and the mounting plate 41 Connect, tighten the wire group through the first take-up wheel 2, and finally connect the wire group on the second take-up wheel 20 around the second pulley 310 and connect with the push rod 45, and the collection personnel control the first wire-reel 2 slowly with one hand Paying off, the other hand stretches the retractable rod 3 to move the dredging device 4 to a suitable position on the river surface, and then the collector controls the first take-up wheel 2 to slowly pay off the line, so that the dredging device 4 falls to the water surface until the bottom of the river, The dredging device 4 falls on the river bed, the ground-inserting rod 13 under the mounting plate 41 is inserted into the mud, and the lower port of the pipe tube 42 also penetrates into the mud.

10-15 minutes after the dredging device 4 falls into the river bed, the collectors first tighten the line on the second take-up wheel 20 by rotating the second take-up wheel 20, and then rotate the second take-up wheel 20 to take up the line 1.
