At present, a central pivot type sprinkler is widely applied in many countries and regions, and compared with other sprinklers, the central pivot type sprinkler has the advantages of high automation degree, large control area, strong adaptability to crops and terrain, good sprinkling uniformity, water saving, energy saving and the like, and has obvious defects that four corners of a square land can not be irrigated, so that the land utilization rate is low.

The Chinese invention patent CN104841585A discloses a controllable variable spray gun, which solves the problem of irrigation of the ground corner of a square plot to a certain extent by arranging the spray gun at the far end of a sprinkler. However, the technology of this patent also has certain drawbacks, as shown in fig. 1, in which the mechanism for driving the spray gun to rotate horizontally adopts a worm and gear structure, and the worm fixedly connected to the rotating shaft of the motor is driven to the worm gear, so as to drive the vertical pipe fixedly connected to the worm gear and drive the spray gun main body fixedly connected to the vertical pipe to rotate horizontally. However, due to the disadvantages of the worm gear structure, on the one hand, when the tooth surface is loaded, the tooth contact state of the worm gear is changed to the bad aspect, that is, deformed to the direction of the oil film break of the tooth surface, and the tooth surface adhesion is easily generated; on the other hand, the tooth-shaped clearance also causes larger transmission error when the worm gear and the worm are assembled. The obvious consequence of the reduced transmission accuracy is that slight changes in the rotational angle of the main body of the spray gun will result in large deviations of the spray point several tens of meters away, so that the use of a worm and gear drive is detrimental to the even irrigation of the spray gun to the farmland.
