[0054] The present embodiment provides a marine DCM processor drill head and automatic flushing system, as shown in Figures 1-5 The multiple rows of flushing assemblies 1 are arranged around the processor 9, and the flushing assemblies 1 comprise:

[0055] The multiple rows of flushing assemblies 1 are arranged around the processor 9, and the flushing assemblies 1 comprise:

[0056] A first support 11;

[0057] A plurality of spray heads 12 are mounted on the first support 11 along the extension direction of the first support 11, and the spray heads 12 are connected to the first support 11 through a horizontal rotating shaft 121. The two ends of the spray head 12 are respectively a first end and a second end, and the first end of the spray head 12 is provided with a fan-shaped nozzle 122 for spraying water flow diffused in the horizontal direction. The connection position of the spray head 12 and the rotating shaft 121 is between the first end and the second end of the spray head 12;

[0058] A spray head support plate 13 is arranged along the first support 11 and is used to support the second ends of the plurality of spray heads 12 to limit the range of rotation of the plurality of spray heads 12 around the rotating shaft 121;

[0059] A force receiving plate 14 is arranged along the first support 11, and the force receiving plate 14 has at least a vertical range of motion. The force receiving plate 14 abuts or is fixed to the second ends of the plurality of spray heads 12, and the projection of the range of motion of the force receiving plate 14 in the vertical direction does not coincide with the projection of the spray head support plate 13 in the vertical direction;

[0060] A first water supply pipeline is connected to the plurality of spray heads 12 of the multiple rows of flushing assemblies 1;

[0061] The pushing mechanism 2 is provided with multiple rows of flushing assemblies 1, and the pushing mechanism 2 comprises:

[0062] A water jet pipe 21 is arranged on one side of each of the force receiving plates 14, and the water jet pipe 21 can make the force receiving plate 14 be in the first position or the second position by starting or stopping water jetting; when the force receiving plate 14 is in the first position, the second ends of the plurality of nozzles 12 fall on the nozzle support plate 13; when the force receiving plate 14 is in the second position, the second ends of the plurality of nozzles 12 are away from the nozzle support plate 13 by a certain distance.

[0063] A second water supply pipeline is connected with the water jet pipes 21 of the plurality of pushing mechanisms 2.

[0064] The automatic flushing system of the marine DCM processor cutter head and drill pipe of the embodiment is shown in FIG. 1, which is arranged in a row of flushing assemblies 1, and generally forms a flushing arrangement around the entire processor 9, and uses the structure of the fan-shaped nozzle 122 to expand the horizontal flushing range of the nozzle 12, and uses the tilting rotation of the flushing assembly 1 to expand the longitudinal flushing range, uses the water flow of the water jet pipe 21 to drive the rotation of the flushing assembly 1, thereby avoiding the introduction of a mechanical transmission structure (referring to a motor and a speed reducer, a transmission shaft, a bearing and other structures), and avoiding the short service life of the mechanical transmission structure in a humid environment. Figure 1 The first water supply pipeline is used to provide water for flushing, and is connected with all the nozzles 12 for water jetting, and the second water supply pipeline does not participate in flushing and is only used to push the force receiving plate 14. The force receiving plate 14 has a large enough area and a light enough mass (a material with low density is selected when the material is selected), and when the water jet pipe 21 jets water, the gravity of the force receiving plate 14 is less than the thrust of the water flow, and the force receiving plate 14 starts to rise and drives the nozzle 12 to rotate around the rotating shaft 121, thereby achieving the tilting water jetting of the nozzle 12. The nozzle support plate 13 limits the height of the second end of the nozzle 12 to drop, so that the nozzle 12 has a fixed position when it is not subjected to force.

[0065] Preferably, as shown in FIG. 1, the side of the force receiving plate 14 facing the water jet pipe 21 is provided with a water baffle 141, and the water baffle 141 is bowl-shaped and has an opening facing the water jet pipe 21. In this scheme, the structure of the water baffle 141 can expand the contact area with the water flow per unit projection area when subjected to the water flow impact, thereby improving the force and reducing the requirement for the flow of the water flow. Figure 5 Preferably, as shown in FIG. 1, the second water supply pipeline is controlled to be opened or closed by an electromagnetic valve. In this scheme, the opening or closing of the second water supply pipeline is controlled by the electromagnetic valve, so that the water jetting force of the water jet pipe 21 can be adjusted, and the angle of the tilting water jetting of the nozzle 12 can be indirectly adjusted.
