Efficient desilting device with good cleaning effect for hydraulic engineering

Abstract

The invention discloses an efficient desilting device with a good cleaning effect for hydraulic engineering, and relates to the technical field of desilting devices. The efficient desilting device comprises a floating plate, hydraulic cylinders are fixedly connected to the four corners of the top of the floating plate, and a mud storage box is fixedly connected to the tops of the hydraulic cylinders. Through an arranged dismounting device, a mud scraping bucket and a driving mechanism can be conveniently dismounted, when a rubber pressing block moves upwards and a threaded rod is rotated, a trapezoidal push block moves upwards, the thrust of the trapezoidal push block to hexagonal blocks at the two sides is released, the two hexagonal blocks get close to each other, and a limiting column slides along the inner wall of a limiting groove; and when a sliding rod rotates, a rotating rod rotates to be separated from the inner wall of a clamping groove, a convex block moves upwards to be separated from the inner wall of a concave groove, limitation of the mud scraping hopper facilitates splitting, disassembling is convenient to expose a first crushing paddle and a second crushing paddle, mud adhering to the surfaces of the first crushing paddle and the second crushing paddle is convenient to clean, repairing and maintaining are convenient, the rotating crushing effect of the crushing paddles is better, and sludge can be cleaned more conveniently.

Description

technical field [0001] The invention relates to the technical field of dredging devices, in particular to a high-efficiency dredging device for water conservancy projects with good cleaning effect. Background technique [0002] At present, river dredging generally refers to the treatment of rivers, which belongs to water conservancy projects. There are many rivers and lakes in our country, and the problem of sediment deposition is very serious. Desilting is an essential process. The dredging of water conservancy projects usually uses dredging machinery to blow and stir the silt deposited on the bottom of the river into turbid water, which flows away with the river water, thus playing a role in dredging. [0003] A kind of water conservancy engineering dredging device disclosed as Chinese patent CN211057900U, it is by setting arc-shaped dredging device below the hull, and the arc-shaped dredging side is equipped with an arc-shaped dredging mouth, and the arc-shaped dredging ...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a high-efficiency dredging device with good cleaning effect for water conservancy projects, which solves the problem that the sand and gravel particles in the mud will cause damage to the propeller blade and a large amount of soil sticks to the propeller blade due to long-term contact with the mud. It is inconvenient to clean the blade, it is inconvenient to disassemble the shell at the propeller blade, and it is inconvenient to repair and maintain the propeller blade regularly, which will lead to poor rotating crushing effect of the propeller blade and poor use effect; it is used for rotary crushing The propeller blades are fixed, and the broken blades have a poor crushing effect on sand and stone in the mud, which will easily cause large particles to block the pipeline when the dredge pump sucks mud, and the effect of mud suction and dredging is poor; mud suction The position of the mouth is fixed, it is inconvenient to adjust the mud suction angle, resulting in unsatisfactory mud suction effect and low working efficiency.
