Embodiment Construction

[0015] refer to figure 1 , a small active rake head, including a fixed body 1. A detachable rake tooth 2 is installed on the front end of the fixed body 1. The fixed body 1 is connected with the movable cover 7 through a pin shaft 6 . The movable cover 7 is connected with the hydraulic cylinder 3, and the hydraulic cylinder 3 controls the movement of the movable cover 7. A high-pressure flushing pipe 4 is installed on the fixed body 1, and a high-pressure flushing nozzle 5 is installed at the front end of the high-pressure flushing pipe.

[0016] When the device is working, it is installed on a small dredger. Control the hydraulic cylinder 3, the hydraulic cylinder 3 controls the movement of the movable cover 7, and the movable cover 7 adjusts the angle between the rake teeth 2 of the rake head and the seabed surface, thereby completing the work of breaking the soil.

[0017] The structure of the device is simple and the production cost is low; the structure of the device ...

Abstract

The invention discloses a small driving rake head and belongs to the technical field of ships. The device comprises a fixing body. The front end of the fixing body is provided with detachable rake teeth, the fixing body is connected with a movable cover, the movable cover is connected with a hydraulic oil tank, and the hydraulic oil tank controls the movable cover to move. The small driving rake head can be used in small dredgers.

Description

technical field [0001] The invention belongs to the technical field of ships, in particular to a small active drag head. Background technique [0002] At present, small trailing suction dredgers all use common rake heads. During the dredging process, the water flow generated when the rake head absorbs water through the dredge pump and the pipeline washes away the sediment at the bottom of the rake head and the pressure difference on the rake head The cohesion of the sediment is destroyed, so that the density of the mixture formed only by the flushing process is low, so that the output of the rake head is not high, and the dredging efficiency is low. The active rake head is a new type of rake head that can increase the efficiency of the dredger. However, due to many reasons such as external dimensions, this active drag head is only used on large dredgers, and has not yet been applied on small dredgers. Contents of the invention [0003] The object of the present invention...
