Cutter suction type silt clearing machine

Abstract

The invention discloses a cutter suction type silt clearing machine in the technical field of silt removers. The cutter suction type silt clearing machine comprises a drive motor, wherein an output shaft of the drive motor is connected with a speed reducer through a coupler; an output end of the speed reducer is connected with a transmission shaft through a coupler; a cutter suction head is weldedto the bottom end of the transmission shaft; and a sludge conveying pipe sleeves the outer wall of the transmission shaft. According to the cutter suction type silt clearing machine provided by the invention, through the interaction of the sludge conveying pipe and a dredge pump, clearing personnel can accomplish the clearing work without the need for directly touching silt, so that the influenceof the silt on the health of the clearing personnel is reduced, the clearing efficiency is high, and the influence on the building process due to the silt removal work is reduced; and through the interaction of a concentration monitor and a programmable logic controller (PLC), the silt sucking and discharging speed of the dredge pump can be controlled or adjusted, so that operating personnel canconveniently grasp the silt clearing progress, and meanwhile, the occurrence of the blockage phenomenon of the sludge conveying pipe or the dredge pump caused by thick silt is reduced.

Description

technical field [0001] The invention relates to the technical field of dredgers, in particular to a cutter-suction sludge cleaner. Background technique [0002] Silt is a kind of cohesive soil deposited in still water or slow flowing water environment, formed by biochemical action, with natural water content greater than fluidity limit and natural void ratio greater than or equal to 1.5. It forms modern sediments under the condition of microbial participation, rich in Contains organic matter, usually grayish black. When the pollutants in the river channel exceed the environmental capacity, the aquatic animals and plants in the river channel will gradually disappear, the water body will become black and smelly, and the landscape and ecological functions will be degraded. This will not only affect the physical and mental health of the surrounding residents, but also restrict the function of the land along the coast Water ecology and regional environment. Dredging is an impor...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of cutter suction sludge cleaning machine, to solve the traditional dredging method proposed in the above-mentioned background technology mostly adopts the construction method of manual cleaning and mechanical transportation and unloading, and the cleaning work in this way is relatively slow and affects During the process of construction, the use of ordinary suction dredging and grab dredging is likely to cause secondary pollution of the water body due to the spread of sludge during the process of sludge cleaning
