Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

A high-pressure cleaning rotating head is combined with figures 1-3 and comprises a base 1 and a connecting shaft 4 fixed on the base 1, wherein a rotating shaft seat 2 is sleeved outside the connecting shaft 4 in a rotating mode, a conical drill bit 3 is installed at the head of the rotating shaft seat 2, and drilling teeth 3a are distributed on the conical surface of the conical drill bit 3. The base 1 and the connecting shaft 4 are hollow to form a water flowing channel A, and the bottom of the base 1 is connected with high-pressure water. The bottom of the connecting shaft 4 is fixed on the base 1 through a hollow threaded interface; referring to fig. 5, a water delivery disk 4b is disposed on the periphery of the connecting shaft 4 to abut against the upper surface of the base 1, and water delivery holes 4c are radially disposed on the water delivery disk 4b so as to guide the high-pressure water of the water flow channel a to the circumferentially-distributed circumferentially-rotating water spray holes 2a on the rotary shaft base 2; referring to fig. 4, axial water-feeding water-spraying holes 1a are distributed at the bottom of the base 1, and the water flow channel a communicates with the axial water-feeding water-spraying holes 1 a.

After the high-pressure water is connected with the high-pressure cleaning rotating head, water flow provides axial feeding force in the pipeline for the whole equipment through the axial feeding water spraying hole 1 a; high-pressure water enters the circumferential rotary nozzle hole from the conveying hole and then is sprayed out, so that the rotary shaft seat 2 generates circumferential rotating force, the conical drill bit 3 at the head is driven to rotate at high speed, and the barrier is cut by using the drill teeth 3a on the conical drill bit 3. In the present embodiment, the circumferential rotation water jet hole 2a is preferably perpendicular to the axis of the rotation shaft seat 2 and does not intersect with the axis, so as to provide a large rotation force. The axial feed water jet holes 1a1a are arranged diagonally outward to ensure the steady advance of the whole apparatus in the pipe.

Preferably, the outer diameter of the conical drill bit 3 is larger than that of the rotary shaft seat 2, and the outer diameter of the rotary shaft seat 2 is smaller than that of the base 1.

Referring to fig. 2 and 3, a nut 4a is mounted on the head of the connecting shaft 4, and the rotary shaft seat 2 is axially limited between the nut 4a and the base 1, so as to facilitate assembly and maintenance.
