Efficient mud suction rake head of river course sediment rake suction boat

Abstract

The invention discloses an efficient mud suction rake head of a river course sediment rake suction boat, and relates to the technical field of dredge boats. The efficient mud suction rake head comprises a rake head device and a rake suction device, wherein the rake head device comprises a front rake head, a side rake head and an outer ring; a mud guide pipe is arranged on the rear mud suction device, and rectangular hole are formed in the peripheral side face of the mud guide pipe; and mud suction holes B are formed in the surface of the rear mud suction device; a mud collecting cavity is formed inside the rear mud suction device and communicates with the mud suction pipeline; a rotary shaft is matched with the front mud suction device; the peripheral side surface of the rotary shaft is matched with the inner surface of the mud guide pipe; and the inner surface of the outer ring is matched with the peripheral side surface of the rear mud suction device; and the mud suction pipeline isfixedly connected with the mud suction pump through a corrugated pipe. The device has the advantages that through the action of rake head device and the rake suction device, the mud is efficiently absorbed, the raking depth is adjusted, the mud raking depth is large, the soil breaking effect is better, and the improvement on the production efficiency and the construction progress of a drag-suctiondredger are achieved.

Description

technical field [0001] The invention belongs to the technical field of dredgers, in particular to a high-efficiency dredge suction head of a dredger suction ship for river mud. Background technique [0002] With the continuous improvement and enhancement of environmental protection awareness such as ecological environment protection and land resource protection in our country, trailing suction dredgers will be used in some river channel cleaning projects, and trailing suction dredgers use rake heads to break the soil and suck mud A dredger with pipe suction. However, during the use of trailing suction dredgers, it may be impossible to adjust the rake head to the required position and dredging depth, resulting in poor dredging effect of the rake head; moreover, the bottom of different rivers sometimes encounters dense compaction In the case of silt, fine sand and hard clay, the bottom of the river is hard to dig, and the rake head cannot effectively break the soil, which aff...

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-efficiency mud suction rake head for a river silt rake suction ship. Through the function of the rake head device and the rake suction device, it solves the problem that the existing rake head cannot effectively crush the soil, thereby affecting the dredge suction.
