JP90-300 winch type hose reel hydraulic folded spray sprinkler
It has many good features as follows:-

1. It is made up of chassis, base frame, winch, PE water pipe, automatic speed-adjusting device, water turbine, four wheels spraying gun cart, folded girder and so on.     
2. The PE pipe enwinds the winch, driven by the water turbine when spraying & changing speed through 6 gear box, which will reverse with the spraying gun cart & girder, spraying a rectangular area, it will finish spraying in the edge of the field.
3. The sprinkler adopts direct water turbine, which can save energy and consumption , and the hydrodynamic conversion of direct water turbine can reach 70% , it is the 1.5 times higher than the hydrodynamic conversion of traditional side compact water turbine. The sprinkler adopts 6 gears gear box for adjusting wor ept speed, which can satisfy different the watering rate requirements for different crops in different seasons.
4. Installed electronic monitoring system device on the sprinkler and manual hydraulic operating system, which make sure the spraying gun cart’ stable up-down and easy operating, moving smartly.
5. The sprinkler is suitable for wor ept in many kinds of areas , such as flatland, hills , can meet different watering rate for multiple kinds of crops. It is suitable for wor ept in the area where the water pump has large flow rate and long irrigating distance.
