Screening device for cleaning silt at river bottom

Abstract

The invention relates to the field of river channel cleaning equipment, in particular to a screening device for cleaning silt at river bottom. The screening device comprises a base, a screening mechanism, a paving mechanism and a vibrating mechanism; the screening mechanism is arranged on the base and is used for screening out garbage, stones and the like from the sucked river bottom silt; the paving mechanism is arranged on the vertical plate, the vertical plate is fixed to the base, the paving mechanism is used for paving silt on the screening mechanism and pushing the silt to move on the screening mechanism, and the paving mechanism can be in transmission connection with the screening mechanism, so that a drying mechanism generates vibration force, and the screening effect on the silt is improved; and the vibrating mechanism is arranged on the vertical plate, is in transmission connection with the paving mechanism and is used for knocking the screening mechanism to prevent the screening mechanism from being blocked in the silt screening process. According to the screening device for cleaning the river bottom silt, garbage, stones and the like in the silt are efficiently screened out, and the garbage and the stones are collected.

Description

technical field [0001] The invention relates to the field of river channel cleaning equipment, in particular to a sorting device for cleaning river bottom mud. Background technique [0002] At present, the river dredging usually uses stirring equipment to stir the silt at the bottom of the river, so that the silt is stirred in the water and drained away with the water flow to achieve the purpose of dredging, but this method makes the silt gradually settle in the process of flowing with the water. , and accumulate in a place downstream, which is easy to cause accumulation again. [0003] Therefore, the existing river channel dredging method is to use suction equipment to pump the sludge to the bank, and because the river bottom sludge is rich in nutrients, organic fertilizer can be made, so as to achieve better dredging effect of river channel sludge and reasonable utilization of sludge . [0004] However, after the existing sludge is sucked, because the sludge at the botto...

Problems solved by technology

[0004] However, after the existing sludge is sucked, because the sludge at the bottom of the river contains large pieces of garbage, stones, etc., and the existing sludge suction equipment cannot screen these garbage, stones, the sludge can be reused. will be polluted by garbage in the process, in view of this, we propose a sorting device for river bottom sludge cleaning
