A rake head device capable of adjusting the depth of rake mud

Abstract

The invention discloses a drag head device capable of adjusting the depth of dredging, and relates to the technical field of dredgers. The invention includes a rake head device, a rake suction device and a hanger; the rake head device includes a rotating column, a rake head and an outer ring; the rake suction device includes a mud filter device and a mud suction pipe; the hanger includes a support frame, a pulley block, and a limit pipe , Fixing device; wherein, the pulley block is connected to the hull through the rotation of the rope; the output shaft of the motor is connected to the rotating column; the rotating column is matched with the limit pipe; the fixing device is matched with the outer ring; the inner surface of the gap is fixed with a mud filter device; A fixed block is arranged on the dredging pipe; the fixed block is fixedly connected with the supporting frame. Through the function of the rake head device and the rake suction device, the present invention has the functions of adjusting the rake mud depth, the rake mud depth is deeper, and the soil breaking effect is better. When the rake head is damaged, the parts can be replaced conveniently and quickly. It achieves the effect of reducing the impact on the construction progress, and also has the advantage of efficient mud suction.

Description

technical field [0001] The invention belongs to the technical field of dredgers, in particular to a drag head device capable of adjusting the dredging depth. 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, the rake head cannot effectively break the soil, and even the rake head is greatl...
