Technical Field
[0001] The invention relates to the technical field of silt removal equipment, in particular to a silt removal device for river channel management. Background Art
[0002] River dredging generally refers to the management of rivers, which belongs to water conservancy projects. Through mechanical equipment, the silt deposited on the riverbed is blown and stirred into turbid water, which flows away with the river water, thereby playing a role in dredging. In order to restore the normal function of the river, a dredging device is needed to manage the river. In the prior art, some dredging devices do not break up the silt before absorbing the silt, resulting in inconvenience in absorbing and cleaning, and reduced cleaning efficiency. To address this problem, the existing dredging equipment generally breaks up the silt, then sucks away the mixture of silt and water together, and then filters the silt therein. For example, the patent with patent announcement number CN214695813U records a dredging method of breaking up the silt. However, this dredging method has a disadvantage in the process of working. The suction structure at the bottom will hinder navigation when not in use, and the dredging depth cannot be adjusted as needed. Secondly, the device uses a filter screen for filtering, which is easy to cause the filter screen to be blocked, and seriously interrupts the entire dredging process.

A discharge pipe 17 for discharging is provided on the lower right side of the buffer box 19, and a one-way discharge valve is provided at the position of the discharge pipe 17. A collecting hopper 16 for collecting materials is provided below the discharge pipe 17. A conveyor belt 14 for filtering the sludge and water mixture is provided below the collecting hopper 16. The middle position of the conveying surface of the conveyor belt 14 is a filter screen. The right end of the conveyor belt 14 extends out of the right end of the hull 11. The right end of the hull 11 is detachably provided with a sludge storage box 12 for collecting sludge. A scraping mechanism for scraping the surface of the conveyor belt 14 is provided above the sludge storage box 12, so that the filtering surface can be continuously turned over, so that the filtered sludge can be sent away in time to avoid sludge accumulation affecting subsequent filtration, so that the device can work continuously;
[0023] The scraper mechanism includes a scraper plate 13, which is pressed against the surface of the filter screen and is connected and fixed to the hull 11 through a positioning rod. The scraper plate can quickly separate the sludge from the conveyor belt 14;
[0024] In order to prevent the filtered water from falling on the hull 11, a guide plate 15 for guiding water is provided between the upper and lower belt surfaces of the conveyor belt 14.
