Rotating speed adjustable water power driving rotary spraying nozzle and speed adjusting method

Abstract

The invention relates to a key device in a water-saving sprinkling irrigation system and particularly to a rotating speed adjustable water power driving rotary spraying nozzle and a speed adjusting method. Water currents enter into a channel to impact an impeller, the impeller generates driving force to drive a shaft A to rotate, the shaft A and a back taper gear belt rotate together, a belt drives a taper gear belt to rotate, and the tapered gear belt and a shaft B rotate together. After the water currents pass through the impeller, the shaft B section which enters into the channel enters into an interior channel of the shaft B through a water inlet hole in the wall of the shaft B, the tail end of the shaft B is connected with the spraying nozzle, and the water currents enter into a spraying nozzle channel after passing through the shaft B to spray to the exterior. According to the speed changing method, a rotating speed ratio of the back tapered gear belt and the tapered gear belt is changed due to the fact that the belt positions in the back tapered gear belt and the tapered belt are changed and accordingly the rotating speed of the spraying nozzle is changed.

Description

technical field [0001] The invention relates to a key device in a water-saving irrigation sprinkler irrigation system. The rotational speed of the sprinkler head can be adjusted, in particular to a hydraulically driven rotary sprinkler head with adjustable rotational speed and a speed regulating method. Background technique [0002] In agricultural water-saving irrigation, nozzles are commonly used sprinkler irrigation equipment, and the speed of nozzles has a great influence on the hydraulic performance of spraying. In the case of no damping mechanism, the greater the driving force of the nozzle, the faster the rotation speed, and the shorter the range of the nozzle, but in different applications, the requirements for the rotation speed of the nozzle are different, and for the same nozzle within the range of one revolution, Changing the speed of the nozzle will often get better spraying effect; therefore, researchers are committed to studying the nozzle at which speed the n...

Problems solved by technology

In the case of no damping mechanism, the greater the driving force of the nozzle, the faster the rotation speed, and the shorter the range of the nozzle, but in different applications, the requirements for the rotation speed of the nozzle are different, and for the same nozzle within the range of one revolution, Changing the speed of the nozzle will often get better spraying effect; therefore, researchers are committed to studying the nozzle at which speed the nozzle has the best spraying performance, and there is still no mechanism for the research on the influence of the speed of the nozzle on the performance. The speed of the nozzle can be adjusted, so it is of great significance to study the influence of the speed of the nozzle on the performance of a hydraulically driven rotary nozzle with adjustable speed.
