Benefits of technology

This patented technology describes an apparatus used during maintenance work without having any parts exposed inside it. By moving away some areas where dirt may get stuck between cutting tools and other equipment, this design improves efficiency while maintains its functionality over time. Additionally, there are various ways to improve the performance of these devices such as adding extra elements like shieldings around them or enhancing their operation speed. Overall, this innovation helps prevent damage caused by debris accumulation and increases operational lifespan.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the performance of cutting machines used during drilling or dredging operations where heavy hydraulics deposits occur due to the presence of thick slugs caused by highly pressurized fluid flowings. Current methods involve manually scraping off these residue masses but they require longer periods of operation before being able to effectively clear them without causing damage. There has developed an improved solution called Shallow Belt Cutting Machine (SBC). It involves creating a shade around the entire area behind the cutting machine's frame to protect against excessive debris buildup. To address issues such as accumulation of hardened material, there proposes continuously developing new ways to improve its effectiveness.

Embodiment Construction

[0030] like Figure 1-Figure 4 As shown in the figure, a large-diameter mud-water balance shield structure prevents mud cake washing, including a cutter head 1, and the cutter head 1 is provided with a nozzle outer casing 2 along the axial direction, and the sprinkler head outer casing 2 is annular It is rotatably connected with the cutter head 1 , and the spray head housing 2 is provided with a flushing mechanism 3 for washing the cutters on the cutter head 1 and the outer surface of the cutter head 1 .

[0031] The cutter head 1 is installed on the front shield 50, and the inner end of the outer casing of the spray head is fixedly connected with the front shield. When the cutter head rotates, the outer casing of the spray head remains stationary.

[0032] In this embodiment, the flushing mechanism 3 disposed on the outer casing 2 of the spray head can flush the cutter head and the cutters on the cutter head at multiple angles, so that the mud cakes on the cutter head can be qui

Abstract

The invention provides a flushing device for preventing mud cakes of a large-diameter slurry balance shield, and belongs to the technical field of shield machine accessories. The spray head comprises a cutter head, a spray head outer shell is arranged on the cutter head in the axial direction in a penetrating mode, the spray head outer shell is annular and rotationally connected with the cutter head, and a washing mechanism used for washing cutters on the cutter head and the outer surface of the cutter head is arranged in the spray head outer shell. The washing mechanism arranged on the spray head outer shell can wash the cutterhead and cutters on the cutterhead in a multi-angle mode, so that mud cakes on the cutterhead can be rapidly and efficiently washed away, when the cutterhead works, the washing mechanism can be contained in the spray head outer shell, the washing mechanism cannot be blocked or damaged by soil when the cutterhead works, and the service life of the cutterhead is prolonged. The service life of the flushing mechanism is prolonged.
