Drag suction dredger drag head

The invention provides a drag suction dredger drag head. The drag suction dredger drag head comprises a movable cover and a rake tooth. According to the drag suction dredger drag head, a movable coverenclosing structure is added on the basis of an existing drag suction dredger drag head. The movable cover enclosing structure is arranged on the movable cover and defines an opening of a cavity structure. The movable cover enclosing structure is used for enabling the movable cover and a dredging working face to form an enclosed space, and the rake tooth is located in the enclosed space. The dragsuction dredger drag head provided by the invention is simple in structure, capable of being dismantled freely and convenient to regulate and replace. The dredge pump suction performance and the soilbreaking capacity of a drag suction dredger can be effectively improved, and the operation efficiency of the drag suction dredger is ensured. 本发明提供了种耙吸式挖泥船耙头，包括活动罩和耙齿；所述耙吸式挖泥船耙头在现有耙吸式挖泥船耙头的基础上，增加活动罩封闭结构，所述活动罩封闭结构设置于所述活动罩上并围设所述
