A gear nozzle comprises an outer pipe, an inner pipe, a connecting pipe, a short pipe, a rotary pipe fitting, a rotary shaft sleeve, a nozzle, a rack and a rotary gear; the inner pipe is positioned in the outer pipe, the inner pipe and the outer pipe synchronously rotate, and the inner pipe does telescopic motion relative to the outer pipe; the connecting pipe is T-shaped, the middle of the connecting pipe is connected with the inner pipe, and two short pipes are respectively connected to two ends of the connecting pipe; the other ends of the two short pipes are respectively connected with a rotating shaft sleeve, and the rotating pipe fitting is arranged between the two rotating shaft sleeves; a rotating gear is fixed on the rotating pipe fitting, a rack is fixed at the corresponding position of the outer pipe, and the rotating gear is meshed with the rack; the nozzle is located on the rotating pipe. When the inner tube moves up and down, the rotating gear is meshed with the rack and can be dragged by the rack in the up-and-down movement process, so that the rotating gear rotates, the rotating gear rotates to drive the rotating pipe fitting to rotate, and the nozzle is rotated.

Further, the connecting pipe is vertically connected with the short pipe through a shaft joint. The shaft joint is screwed with the outer teeth of the connecting pipe through the inner teeth, the short pipe is screwed with the inner teeth through the outer teeth, and the connection is convenient.

Furthermore, the short tubes are divided into a front short tube and a rear short tube, the front short tube is connected with the connecting tube, the rear short tube is connected with the rotating shaft sleeve, and the front short tube is connected with the rear short tube through the union cap. The short pipe is connected with the takeover before respectively, and the back short pipe is connected with the pivot cover, installs rotatory pipe fitting in the pivot cover, and the completion back is passed through and the cap links together two parts, fast assembly to the depth of parallelism of rotatory pipe fitting of regulation that can be accurate and takeover.

Further the inner tube is telescoped relative to the outer tube a distance sufficient to rotate the swivel fitting 180 °.

Furthermore, two nozzles are arranged and positioned on two sides of the rotating gear, and the nozzles are vertical to the rotating pipe fitting; the nozzle is directed vertically upwards when the inner tube extends a maximum distance beyond the outer tube and vertically downwards when the inner tube extends a minimum distance beyond the outer tube.

Has the advantages that: compared with the prior art, the utility model has the advantages of:

1) the nozzle realizes 180-degree rotation from top to bottom, thereby reducing dead angles in the cleaning process and enlarging the effective cleaning range;

2) the operation is stable and smooth without blockage;

3) all the parts are movably connected, the assembly is quick, and the adjustment is accurate.
