Embodiment Construction
[0014] refer to figure 1 , the present invention is a device for increasing the ground pressure of a rake head, comprising a rake pipe 4 hinged with the dredger and a rake head main body 1 arranged at the end of the rake pipe 4, a resistance conversion plate 2 is hinged on the top of the rake head main body 1, The resistance conversion plate 2 is inclined relative to the top surface of the drag head main body 1, and the upper side plate surface of the resistance conversion plate 2 faces the advancing direction of the drag head main body 1. A driving device 3, the two ends of the driving device 3 are respectively connected to the rake head main body 1 and the resistance conversion plate 2.
[0015] In this drag head-to-ground pressure increasing device, since the resistance conversion plate 2 is inclined and the upper side plate faces the advancing direction of the drag head body 1, when the drag head body 1 advances underwater, the water flow hits the upper surface of the resi...

The invention discloses a rake head ground pressure increasing device. The rake head ground pressure increasing device comprises a rake tube which is hinged with a dredge boat and a rake head main body which is arranged at the tail end of the rake tube, and further comprises a telescopic drive device, wherein a resistance conversion plate is hinged on the rake head main body; the resistance conversion plate is inclined, and the upper side plate surface faces towards the forward direction of the rake head main body; the two ends of the drive device are separately connected with the rake head main body and the resistance conversion plate; when the rake head main body forwards underwater, water flow impacts the resistance conversion plate, so that one part of resistance of the rake head mainbody is converted to be downward pressure through water flow, and pressure, on a seabed surface, of the rake head main body is increased; and the drive device stretches out and draws back to change anangle between the resistance conversion plate and the top surface of the rake head main body, so that an angle between the upper side plate surface of the resistance conversion plate and the speed direction is changed, and resistance conversion degree is regulated, and therefore, the size of increased pressure can be accurately controlled. The rake head ground pressure increasing device is used for the technical field of ships.
Description
technical field [0001] The invention relates to the technical field of ships, in particular to a device for increasing the ground pressure of a rake head. Background technique [0002] At present, the construction of dredger rake head mainly depends on the weight of the rake head itself, and the decompression adjustment is carried out through the wave compensator. When encountering special soil quality and need to increase the ground pressure of the rake head, the only way to increase the weight of the rake head is to increase the weight of the rake head, but the increase in the weight of the rake head will affect the strength of the winch and the hull, so it is not feasible. Contents of the invention [0003] The object of the present invention is to provide a drag head-to-ground pressure increasing device with convenient pressurization and simple structure. [0004] The technical scheme that the present invention takes is: [0005] A device for increasing the ground pr...
