AI Technical Summary

Technical Problem

Existing riverbed sediment remediation devices are prone to wear or deflection of the slotted gears when dealing with larger rocks, resulting in an unstable wire-laying process and difficulty in effectively cleaning larger rocks from the riverbed.

Method used

A device for the remediation of urban riverbed sediment, comprising a stone filtering mechanism and a material pushing mechanism, was designed. The stone filtering mechanism uses a drum-shaped sleeve and a hook rake to screen out large stones, while the material pushing mechanism uses an eccentric wheel and a pushing rod to assist the stones in sliding down, avoiding direct contact between the slotted gears. Combined with a precise gear transmission system, the stability and efficiency of the device are ensured.

Benefits of technology

It effectively extends the service life of slotted gears, avoids wear and deflection, improves stone cleaning efficiency, and ensures the stability and energy saving of the fiber laying process.

Abstract

The invention belongs to the technical field of sludge remediation and treatment, and discloses an urban river sediment remediation and treatment device and method.The urban river sediment remediation and treatment device comprises a measuring ship, a towing bracket is installed at the bottom of the measuring ship, and a mounting plate is fixedly connected to the tail of the towing bracket; a plurality of slotting gears are mounted in the middle of the mounting plate, through cooperation of structures such as hook rakes, drum waist sleeves and shaft rods, the rotating hook rakes continuously fish out large stones in bottom mud to reach the surface of the drum waist sleeves with the high middle and the low two sides, meanwhile, the shaft rods generate extrusion force in reciprocating spiral grooves through round protruding blocks, and the large stones are driven by the shaft rods to rotate. The drum waist sleeve does axial reciprocating motion in the rotating process, stone is accelerated to be discharged to the two sides through slight axial vibration, and the raking depth is synchronously changed according to the adjusting depth of the towing bracket, so that the service life of the slotting gear is effectively prolonged, and the slotting gear is prevented from being abraded or deflected.
