Abstract
A hydraulic excavating drag head belongs to the technical field of ship parts. The excavating drag head comprises a wash pipe and a wash branch pipe fixedly connected with the middle part of the wash pipe; the other end of the wash branch pipe is fixedly connected with the top part of the end of a cavity cover; and the other end of the cavity cover is rotationally connected with a sand suction inlet of a drag pipe through a rotating shaft. The utility model adopts the structure that a hydraulic angle adjusting device is arranged at the top part of the cavity cover in a matched manner, a drag tooth is formed on one side of the bottom cavity cover in a matched manner, and a wash opening is formed at the root part of the drag tooth in a matched manner, therefore, the angle of the excavating drag head can be arbitrarily adjusted according to the depth of mud, and the mud is loosened through the washing of the wash opening, which is convenient for the mud to be sucked into a ship through the sand suction inlet of the drag pipe. The hydraulic excavating drag head has the advantages of simple operation, convenient excavation, and improvement on the operating efficiency.

At present, the excavation drag head that uses mainly is the excavation drag head of common movable, drag head is unadjustable with the angle that the rake pipe is inhaled husky import, when dredging operation, can change along with the fluctuations in seabed, the stressed instability of rake teeth, be difficult for when silt particle is thicker excavating, and drag head is fragile, operating efficiency reduces.
The utility model content
At the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of fluid pressure type adjustable excavation drag head.
Described a kind of fluid pressure type excavates drag head, comprise jet water spout, the bath arm of fixedlying connected with the jet water spout middle part, fixedly connected with cover top, termination, chamber in the other end of bath arm, the other end of chamber cover is inhaled husky import with the rake pipe and is rotationally connected by rotating shaft, it is characterized in that cover top, described chamber also is equipped with the fluid pressure type angle regulator, described fluid pressure type angle regulator reaches two bearings that are equipped with the hydraulic cylinder two ends by hydraulic cylinder and constitutes, cover bottom, described chamber one side is equipped with rake teeth, and the root of rake teeth is equipped with flush port.
Described a kind of fluid pressure type excavates drag head, it is characterized in that described hydraulic cylinder reaches the ram piston that closely is arranged in the cylinder body by cylinder body and constitutes.
Described a kind of fluid pressure type excavates drag head, it is characterized in that the cylinder body internal diameter of described ram piston diameter and hydraulic cylinder is complementary, can be movable in cylinder body.
Described a kind of fluid pressure type excavates drag head, it is characterized in that described rake pipe inhales husky import lateral location and be equipped with rubber fender.
Described a kind of fluid pressure type excavates drag head, it is characterized in that it is variable-diameter structure that described rake pipe is inhaled husky import, and the diameter of import department is less than the diameter of rake pipe.
Described a kind of fluid pressure type excavates drag head, it is characterized in that described bath arm made by rubber hose.
Above-mentioned a kind of fluid pressure type excavates drag head, comprise jet water spout, the bath arm of fixedlying connected with the jet water spout middle part, fixedly connected with cover top, termination, chamber in the other end of bath arm, the other end of chamber cover is inhaled husky import with the rake pipe and is rotationally connected by rotating shaft, the utility model adopts at cover top, chamber and is equipped with the fluid pressure type angle regulator, can control the angle of rake teeth by remote control adjustment, easy to operate, and a side is equipped with rake teeth bottom the cover of chamber, and the root of rake teeth is equipped with flush port, washes by water by flush port, mud is fluffed, mud is inhaled husky import by the rake pipe and is inhaled into cabin, and it is convenient to excavate, and increases work efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the local enlarged diagram of rake teeth of the present utility model.
Among the figure: 1-jet water spout, 2-rubber fender, 3-cylinder body, 4-ram piston, 5-bearing, the 6-arm of washing by water, 7-chamber cover, the 8-rake teeth, the 9-flush port, the 10-rotating shaft, 11-rake pipe is inhaled husky import.
The specific embodiment
Below in conjunction with Figure of description and embodiment the utility model is further described:
As shown in Figure 1, a kind of fluid pressure type excavates drag head, comprise jet water spout 1, the bath arm 6 of fixedlying connected with jet water spout 1 middle part, the other end of bath arm 6 is covered top, 7 termination with the chamber and is fixedlyed connected, the other end of chamber cover 7 is inhaled husky import 11 with the rake pipe and is rotationally connected by rotating shaft 10, described chamber is covered 7 tops and also is equipped with the fluid pressure type angle regulator, described fluid pressure type angle regulator reaches two bearings 5 that are equipped with the hydraulic cylinder two ends by hydraulic cylinder and constitutes, described hydraulic cylinder reaches the ram pistons 4 that closely are arranged in the cylinder body 3 by cylinder body 3 and constitutes, cylinder body 3 internal diameters of ram piston 4 diameters and hydraulic cylinder are complementary, can be free up and down in cylinder body 3, thus the angle of inclination of adjusting rake teeth 8.Described rake pipe is inhaled husky import 11 and is variable-diameter structure, and the diameter of import department is less than the diameter of rake pipe, and inhaling the outer mud of husky import can be inhaled into cabin with more speed.Rake pipe is inhaled husky import 11 lateral location and is equipped with rubber fender 2, and the pipe and drag head rises when hanging up and the ship hull plate collision of preventing to dredge, described bath arm 6 are made by rubber hose, and the arm 6 of washing by water during digging operation is scalable.
As shown in Figure 2, described chamber is covered 7 bottoms, one side and is equipped with rake teeth 8, and the root of rake teeth 8 is equipped with flush port 9.
This fluid pressure type excavates drag head when digging operation, according to excavation depth, logical moving remote control adjustment ram piston 4 at hydraulic cylinder by the position in the cylinder body 3, drive rotating shaft 10 rotations chamber cover 7 is adjusted to certain angle, the beginning operation, easy to operate, all can regulate at any time, the chamber is covered the root that 7 bottoms, one side is equipped with rake teeth 8 and is equipped with flush port 9, bath fluffs mud during operation, is beneficial to mud and is inhaled into cabin by the husky import of rake pipe suction, and is simple to operate, it is convenient to excavate, and increases work efficiency.
