Water jet driving spray-head with elevation angle automatic-adjustment function

Abstract

The invention relates to a water jet driving spray-head with an elevation angle automatic-adjustment function, belonging to key equipment for a water- saving irrigation and sprinkling irrigation system and being suitable for solving the problem that the jet range automatically changes when the spray-head rotates. The water jet driving spray-head comprises a mounting riser, a guide rail disc, a spray-head rotator, a spray-head elbow, an elevation angle adjusting mechanism, a spray pipe, a jet element body and a guide rod, wherein a rail is arranged at the periphery of the guide rail disc, and the guide rail is set according to the change rule of the jet range; the elevation angle adjusting mechanism consists of an internal spherical surface joint, an outer sleeve, an internal spherical surface joint and a rubber ring; and when the spray head works, the spray pipe rotates to drive the guide rod to rotate together, the guide rod extends into one end of the guide rail and travels along the guide rail, the guide rail moves up and down due to periodic vertical change of the guide rail, the spray pipe moves up and down while horizontally rotating so as to drive the internal spherical surface joint to rotate along the radian of the spherical surface in an up-down angle range, and therefore the elevation angle of the spray-head can be automatically adjusted.

Description

technical field [0001] The invention belongs to the key equipment of the water-saving irrigation sprinkler irrigation system, which is suitable for solving the problem of automatic change of the shooting range when the sprinkler head rotates, and particularly refers to a water jet driven sprinkler head whose elevation angle is automatically adjusted along with the guide track. Background technique [0002] The sprinkler is the key equipment that affects the quality of sprinkler irrigation. The traditional sprinkler is mainly a full-circle sprinkler rocker sprinkler. Leaked spray, over-spray or out-of-bound spray phenomenon will easily cause waste of water resources. In the combination area, the full-circle spraying area is superimposed unevenly, and the uniformity coefficient decreases. To avoid missed spraying and out-of-boundary spraying, the sprinkler head is required to change the original circular spraying area to adapt to the sprinkling irrigation of small plots and i...
