The utility model aims at providing a rotatory nozzle sets up the oil storage chamber between the bearing, utilizes being connected between damping oil lubrication bearing and the rotation axis to reduce the required precision to technology.

The purpose of the utility model is realized like this: a rotary nozzle comprises a shell, a rotating shaft, a shaft core and a rotating head, wherein the rotating shaft is arranged in the shell in a penetrating mode, a bearing is arranged between the rotating shaft and the shell, and the rotating head is arranged at the head of the rotating shaft and rotates along with the rotating shaft; the inside cavity of axle core wears to locate the rotation axis hole, supplies water for the rotating head, and the rotation axis is worn out and the water supply connector connection bottom the shell to axle core bottom, be provided with the oil storage chamber between the bearing, the oil storage intracavity is filled there is damping oil.

Furthermore, water lubrication is adopted between the shaft core and the inner hole of the rotating shaft.

Furthermore, the bottom of the shaft core is connected with a water inlet connector through a nut.

Further, the rotating head is in threaded connection with the head of the rotating shaft.

Furthermore, the tail part of the bearing is provided with an annular flange, the annular flange is supported on the mounting openings at the two ends of the shell, and the head part of the bearing extends into the inner cavity of the shell.

Furthermore, the rotating shaft is provided with a sealing section above the thread section, and the sealing section is provided with a sealing ring.

Detailed Description

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

A kind of rotatory nozzle, combine fig. 1 and fig. 2, including outer casing 2, rotating shaft 6, axle center 7 and rotating head 1, the rotating shaft 6 is worn to locate in outer casing 2 and set up the bearing 4 with the outer casing 2, distribute the spray nozzle 1a on the rotating head 1 and the threaded connection is in the head of rotating shaft 6 and rotate together with rotating shaft 6; the inside cavity of axle core 7 is worn to locate 6 holes of rotation axis, for rotating head 1 water supply, and rotation axis 6 is worn out and is connected with the water supply connector 3 of shell 2 bottom to axle core 7 bottom. Specifically, referring to fig. 2, an oil storage chamber 5 is arranged between the bearings 4, and damping oil is filled in the oil storage chamber 5.

Wherein, a water lubricating structure in clearance fit is arranged between the shaft core 7 and the inner hole of the rotating shaft 6. The bottom of the shaft core 7 is provided with a barb-shaped structure and is hooked on the nut 8, and the nut 8 is in threaded connection with the water inlet joint 3, so that the water inlet of the shaft core 7 is tightly propped against the conical water inlet of the water inlet joint 3. The water inlet joint 3 is fixed at the tail part of the shell 2 by screw threads.

Referring to fig. 2, 5 and 6, the bearing 4 is provided at a rear portion thereof with an annular flange 4a, the annular flange 4a is supported on the mounting ports 2a at both ends of the housing 2, and a head portion of the bearing 4 is extended into the inner cavity of the housing 2, thereby forming an oil storage chamber 5 for storing damping oil between the two bearings 4. The lower end of the rotating shaft 6 is provided with a projection 6c, and the projection 6c is matched at the bottom of the lower bearing 4. Referring to fig. 6, needles are distributed in the inner hole of the bearing 4, and the bearing 4 is matched with the rotating shaft 6 by using the needles.
