TECHNICAL FIELD

[0001] The utility model relates to the technical field of polluted bottom mud treatment, specifically to a bottom mud dredging device for polluted bottom mud treatment. BACKGROUND

[0002] Polluted bottom mud is an important component of natural water area, but when the water area is polluted, some pollutants in the water can be stored in the bottom mud through sedimentation, particle adsorption and other ways. These pollutants can be released into the water body under appropriate conditions, becoming a secondary pollution source. This pollution phenomenon is called bottom mud pollution.

[0003] The prior art discloses a bottom mud dredging device for polluted bottom mud treatment, which comprises a ship body, a supporting frame is fixedly connected to the top of the ship body, a frame rod is fixedly connected to the left end of the supporting frame, a first guide wheel is fixedly connected to the left end of the frame rod, a first steel cable is wound around the outer surface of the first guide wheel, a positioning steel column is fixedly connected to the lower end of the first steel cable, and the lower end of the positioning steel column penetrates through the platform and the ship body and extends to the outside of the ship body. The bottom mud dredging device for polluted bottom mud treatment is characterized in that a mud grabbing rod that can rotate up and down is sleeved at the bottom of the positioning steel column, a third steel cable is connected to the top surface of the mud grabbing rod, a sliding ring that can slide on the outer surface of the positioning steel column is connected to the other end of the steel cable, and the lifting and lowering of the mud grabbing rod are controlled by a motor. When the positioning steel column needs to be pulled out, the mud grabbing rod is first lifted, and then the positioning steel column is lifted to avoid the difficulty in pulling out the positioning steel column due to the blocking of the mud grabbing rod, thereby improving the portability of the positioning steel column and the efficiency of engineering operation.

The metal connecting plate 12 is installed on the upper end of the positioning steel column 11 and is slidably connected to the left end of the clamping assembly 13. The metal connecting plate 12 is installed on the upper end of the lifting device 14. The support frame 136 and the metal connecting plate 12 can determine the position of the lifting device 14. There are two lifting devices 14, which are distributed front and back. The two lifting devices 14 are controlled by a PLC controller, which allows the two lifting devices 14 to adjust the position of the metal plate 131 and the clamping frame 132. The lifting device 14 is installed on the right end of the clamping assembly 13.

[0026] The clamping assembly 13 includes a first metal plate 131, a first clamping frame 132, a clamping roller 133, a second clamping frame 134, a second metal plate 135, a support frame 136, and a movable roller 137. The movable roller 137 is tactilely connected to the inner front wall surface of the support frame 136. A metal connecting plate 12 is threadedly connected to the top surface of the support frame 136. The metal connecting plate 12 and the support frame 136 are threadedly connected, which allows the position of the metal connecting plate 12 to be determined, facilitating its disassembly and replacement.
