Spraying irrigation spray nozzle capable of automatic rotary spraying

Abstract

The invention discloses a spraying irrigation spray nozzle capable of automatic rotary spraying. The spraying irrigation spray nozzle comprises a spraying irrigation frame (5), a rotation body (4) and two spray nozzle main bodies (3), wherein the two spray nozzle main bodies (3) are fixed at the upper end of the rotation body (4); a spray nozzle is arranged at the front end of each spray nozzle main body (3); a radial main nozzle (2) is arranged at the top end of the spray nozzle (1); the side surfaces of the two spray nozzles (1) are provided with an auxiliary nozzle (8) and an auxiliary nozzle (9) respectively; and the two auxiliary nozzles (8, 9) form a 180-degree angle. When in use, the water flow sprayed by the two auxiliary nozzles (8, 9) generates a rotation moment and enables the two spray nozzle main bodies (3) to rotate. In the invention, the spray nozzles rotate under the reacting force of water flow, a base or bracket receives uniform force and does not topple easily, and a relatively high bracket can be arranged. The main nozzle and auxiliary nozzles spray outwards in different directions and distances to form a uniform spraying zone which is beneficial for saving water and improving the spraying irrigation effect.

Description

technical field [0001] The invention relates to a sprinkling irrigation device, in particular to a sprinkling irrigation nozzle which uses reaction force to rotate automatically. Background technique [0002] Sprinkler irrigation is a mechanized irrigation method, and it is also an efficient irrigation technology widely adopted in the world. Compared with traditional flood irrigation, sprinkler irrigation can generally save 30-50% of water and increase crop yield by 20-30%. In the prior art, the sprinkler head used is as figure 1 As shown, it includes the nozzle body 3 connected in sequence, the rotating body 4 and the sprinkler frame 5, the nozzle 1 is fixed on the nozzle body 3, the front end of the nozzle 1 is provided with the main nozzle 2; the nozzle body 3 is provided with a water separator 6, and the rotating body 4 A double-wing rocker 7 is arranged on the top, and the rocker 7 is provided with a water-injecting guide body on the rocker arm corresponding to the mai...

Problems solved by technology

[0005] Secondly, because the setting of the sprinkler nozzle must be higher than the height of the crops, otherwise the sprinkler irrigation operation cannot be carried out. The fan-shaped reciprocating swing of the rocker-arm sprinkler head is greatly affected by the wind force and wind direction when the height of the sprinkler head increases, which makes the sprinkler irrigation unstable and unstable. Increased uniformity, such as corn, sorghum, etc., and these crops can only be flooded when they encounter drought during the grain filling period
