They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0022] With current technology, spray guns can only rotate circumferentially perpendicular to the ground by using a rotating tube mounted on a base and the force of the water jet. As a result, the area covered by the sprayed water is always at a constant distance from the spray gun, and the distance of the water jet cannot be adjusted. Therefore, when irrigating farmland, it is necessary to repeatedly change the position of the spray gun to reach areas that the spray gun cannot reach, which leads to low irrigation efficiency and waste of manpower.

[0023] To solve the above problems, such as Figures 1 to 3 As shown, this utility model provides an adjustable-angle rotary spray gun, including a base 1, a rotating tube 2, a connecting tube 3, and a water pipe 4. The base 1 is fixed on a horizontal plane. The rotating tube 2 is rotatably mounted on the base 1 and rotates around an axis perpendicular to the horizontal plane.

A nozzle is provided on the water pipe 4. The rotating tube 2 is connected to the outer connecting tube, which provides a water source.

[0024] When the angle of the water column sprayed by the nozzle needs to be adjusted, the water pipe 4 or the adapter pipe 3 is held so that the adapter pipe 3 can rotate around the fixed pin 22, since the second arc-shaped part 31 and the first arc-shaped part 21 both have the axis of the fixed pin 22 as the rotation axis, so that freedom can be provided for the relative movement of the adapter pipe 3 in the rotating pipe 2, the angle between the water pipe 4 and the horizontal plane can be changed, and then the angle between the water column sprayed by the nozzle and the ground can be changed, if the angle between the water column sprayed and the ground can be changed, the distance of the water column from the spray gun after being sprayed can be changed, according to the law of physics, when the angle between the water column sprayed and the ground is close to 45°, the spraying distance is the farthest, and when the angle between the water column sprayed and the ground is far away from 45°, the spraying distance will be closer and closer, and accordingly the spraying distance of the spray gun can be changed, so that the spraying distance of the spray gun of the utility model can be adjusted, the coverage range of the spray gun is larger, and the number of times of moving the spray gun is reduced.

[0025] The angle-adjustable rotary spray gun further comprises a first arc-shaped plate 5, the first arc-shaped plate 5 is formed with two groups of fixing holes, the adapter pipe 3 is formed with two groups of fixing columns 33, the fixing columns 33 are correspondingly inserted into the fixing holes, and the two groups of fixing columns 33 can fix the first arc-shaped plate 5 on the adapter pipe 3.
