Rotationally rising and falling pop-up sprinkler

Abstract

The invention discloses a rotationally rising and falling pop-up sprinkler. The sprinkler comprises an internal thread fixed casing pipe, a screw rod, a rotationally rising and falling pipe, a spiral nozzle and a floating disc, wherein a water flow enters the internal thread fixed casing pipe, the water pressure drives the floating disc upward and the floating disc bears the rotationally rising and falling pipe and the spiral nozzle to rotationally move upward along the screw rod; the rotationally rising and falling pipe is installed in the internal thread fixed casing pipe in a sleeving manner, can be driven by the water flow to rotationally rise and can rotationally fall with the help of own gravity rather than the water flow; the spiral nozzle is provided with an external thread; the lower end of the spiral nozzle can be connected with the rotationally rising and falling pipe. The sprinkler does not affect tillage in the non-irrigation period, can save labor and materials during irrigation and can also meet the requirements of economy, reasonableness, durability in use and convenience in popularization and application.

Description

Technical field [0001] The invention relates to a rotary lifting control device, in particular to a rotary lifting buried nozzle. Background technique [0002] Sprinkler irrigation technology is that pressurized water formed by pump pressure or natural drop is sent to the field through a pressure pipe, and then sprayed into the air through a sprinkler to form fine water droplets, which are evenly sprayed on the farmland to achieve the purpose of irrigation. Sprinkler irrigation is greatly affected by wind and high equipment investment. There are many forms of sprinkler irrigation systems, mainly: mobile, semi-fixed and fixed pipe sprinkler irrigation systems; fixed pipe sprinkler irrigation systems can be buried underground or laid on the ground; semi-mobile and mobile pipes Sprinkler irrigation requires a lot of manpower to move branch pipes, and if poorly managed, the branch pipes are easily damaged, especially the soil that has just been sprayed, and it is also easy to damage...

AI Technical Summary

Problems solved by technology

Sprinkler irrigation is greatly affected by wind and equipment investment is high

There are many forms of sprinkler irrigation systems, mainly including: mobile, semi-fixed and fixed pipeline sprinkler irrigation systems; branch pipes of fixed pipeline sprinkler irrigation systems can be buried underground or laid on the ground; semi-mobile and mobile pipelines Sprinkler irrigation requires more manpower to move the branch pipes, and if the management is not good, the branch pipes are easily damaged, especially the soil that has just been sprayed, and it is easy to damage the seedlings and destroy the soil
