Cover, rake arms body interior is provided with hollow cavity, and rake arms body offers row's mud-suction hole near drag head mechanism main drag head side,
Mud-suction hole hollow cavity intrinsic with rake arms is connected, and the front end of rake arms body is machined with connecting hole, and connecting hole is used for connecting
Transport the pipeline of soil.
This utility model is used for the rake arms of drag head mechanism, and wherein said rake arms body is welded by multi-sheets.
This utility model is used for the rake arms of drag head mechanism, and wherein said rake arms top is provided with support base.
The rake arms difference from prior art that this utility model is used for drag head mechanism is that this utility model is used for drag head
The rake arms of mechanism improves on the basis of existing drag head mechanism, simplifies the overall structure of drag head mechanism, opens inside rake arms
If hollow cavity, the pipeline of dredge pump is made to be directly connected to hollow cavity, such dredging tube road is merged with the fixing pipeline of drag head, permissible
Avoid the excessive problem of the pipeline in drag head mechanism, and pipeline connects it is also possible to avoid pipeline and drag head machine from drag head front end
The contact of structure other structures, thus prevent from mutually colliding the contingency of generation.This utility model is used for the rake arms of drag head mechanism
It is additionally provided with protective cover, corresponding with main drag head external shape, effective protective action can be played to main drag head.
Below in conjunction with the accompanying drawings the rake arms for drag head mechanism of the present utility model is described further.
