Description

High-pressure pipe dredging nozzle with self-drilling function

technical field

The utility model relates to a high-pressure pipeline dredging nozzle with the function of self-drilling, which belongs to the technical field of dredging nozzles used for supporting pipeline dredging vehicles.

Background technique

The current high-pressure pipeline dredging nozzles can only spray backward water column in the pipeline, which is more effective for loose blockages, but cannot be effectively removed when encountering hard blockages. Therefore, the existing hard blockages cannot be effectively removed. Clear the question.

Contents of the invention

The purpose of the utility model is to solve the technical problem that existing high-pressure pipeline dredging nozzles cannot effectively remove hard blockages, and provide a high-pressure pipeline dredging nozzle with self-drilling function.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A high-pressure pipe dredging nozzle with self-drilling function, which consists of a quick installation joint, a sealed bearing, a bearing retaining ring, a rotating nozzle and a drill bit, and the rotating nozzle is composed of a cylinder, a first cone, a second cone and a third Cone structure, one end of the cylinder is connected to the large end of the first cone, the small end of the first cone is connected to the small end of the second cone, and the large end of the second cone is connected to the large end of the third cone connected, and the cylinder, the first cone, the second cone and the third cone are connected as one, the center of the other end of the rotating nozzle cylinder is provided with a bearing hole, and the small end of the third cone of the rotating nozzle The center of the end face is provided with a threaded hole connected with the drill bit. The center of the rotating nozzle is provided with a water spray channel and the water spray channel connects the bearing hole with the threaded hole. The water spray hole, the rear spray hole on the inclined side communicates with the water spray channel in the center of the rotary nozzle; the inner ring of the sealed bearing and the bearing retaining ring are installed on the shaft provided at one end of the quick installation joint, and the sealed bearing is fixed on the shaft through the bearing retaining ring , the outer ring of the sealed bearing is installed in the bearing hole of the rotary sprinkler head and the sealed bearing is fixed in the bearing hole by screws, the drill bit is installed in the threaded hole of the rotary sprinkler head and the front water spray hole set in the center of the drill bit is connected to the screw hole of the rotary sprinkler head The sprinkler is connected.

Further, the angle between the centerline of the rear spray hole on the oblique side and the centerline of the spray channel of the rotary nozzle is 20-25°.

The beneficial effects of the utility model are:

1. Change the rotary nozzle and the quick installation joint into a split type, and connect them through sealed bearings, so that the rotary nozzle rotates relative to the high-pressure hose;

2. By changing the angle of the water spray hole on the inclined side, the high-pressure water column is sprayed to the rear of the inclined side, so that the rotating nozzle can generate the force of rotating around the axial direction, and ensure that the rotating nozzle can rotate automatically during the forward process;

3. Add a drill bit before the rotary nozzle, so that the rotary nozzle can not only have the cleaning function, but also can cut hard blockages through the rotation of the drill bit, improving the cleaning efficiency;

4. Make a hole in the center of the drill bit to ensure that water can also be sprayed in front of the drill bit, which can provide a better drilling and cutting effect. Compared with the background technology, the utility model has the advantages of simple structure, high cleaning efficiency and ability to effectively remove hard blockages.
