A multifunctional dredging machine

Abstract

The invention relates to the technical field of dredging machines, in particular to a multifunctional dredging machine, which comprises a dredging machine body, a dredging mechanism, and a secondary crushing mechanism. The mechanism includes a sediment pump connected with a mud conveying pipe and a rotatable twisting head. The twisting head is connected with the sediment pump through a telescopic mechanism. The secondary crushing mechanism is arranged on the mud conveying pipe. The secondary crushing mechanism includes a connecting pipe and a rotatable The crushing head is arranged in the connecting pipe, and the sludge in the mud conveying pipe can be crushed by the secondary crushing mechanism; the invention provides a multifunctional dredging machine, which is simple to operate, has a wide dredging range, and improves the The dredging effect reduces manpower and material costs.

Description

technical field [0001] The invention relates to the technical field of dredging machines, in particular to a multifunctional dredging machine. Background technique [0002] After a long-term use of a river channel or aquaculture pond, a lot of silt will accumulate at the bottom. At this time, the sludge needs to be cleaned to prevent the normal operation of the boats on the river channel and the breeding effect of the aquaculture pond. [0003] The most commonly used dredging methods are: [0004] (1) Use an excavator for sludge cleaning. [0005] This method is suitable for rivers with less water or almost dry. This method needs to be drained in advance, but whether it is discharging sewage or dumping silt, it will cause secondary pollution. For individual rivers, it is necessary to re-ship the silt before it can be transported to the shore, which greatly reduces the efficiency and wastes manpower and material resources. [0006] (2) Underwater dredging. [0007] In the...

Problems solved by technology

Generally, there are two methods of dredging grab ship and cutter suction dredger. The dredging grab ship has low work efficiency and there is also the phenomenon of hollowing out the river bottom, while the suction port and pump of the cutter suction dredger are often blocked. The dredging is not thorough, and when cleaning the silt in uneven places, the cleaning range is limited, and the cleaning effect is not ideal. It is even more inconvenient to carry out dredging operations in narrow rivers or breeding ponds, and wastes manpower and material resources.
