Basic Information of Center Pivot Sprinkling Machine
This center pivot sprinkling machine is also called pointer-type sprinkling machine, a kind of irrigation equipment featured by saving water and improving productivity. It is mainly used for irrigating various agricultural crops, industrial crops and pastures, such as corn, wheat, vegetables, sugarcane, cotton, seedlings and grass, etc.
Center Pivot Sprinkling Machine Features and Advantages
- Optional engine of electricity grid or diesel generator set.
- Safe and reliable electrical alignment control system.
- The over-watering protection device saves water; the automatic display unit saves operation troubles.
- Equipped with impact sprinkler with more than 85% uniformity coefficient; can be used for high-uniformity chemicals and fertilizers sprinkling.
- This machine can work in the fields with slopes of up 25%.
- Its important components and parts are all hot-dipped galvanized for 15 year’s anti-corrosion warranty.

Center Pivot Sprinkling Machine Working Principle
When the machine begins to work, start the remotest tower wagon first, and according to the working condition, separately start the neighboring tower wagon. Then all the tower wagons start to work one by one, rotating around the center pivot to complete the automatic spraying work of circular shape.

Center Pivot Sprinkling Machine Structure
- Center pivot: it is the gyration center and the water inlet of the irrigation system, and its base plate can be fixed on the reinforced concrete base to keep stable.
- Sprinkling system: consists of sprinkling side-pipe and spraying nozzle.
- Girder: it is the elementary unit of the center pivot sprinkling machine, and sprinkling side-pipe is its structural component.
- Tower wagon: includes tower post, road wheel and driving system; it is not only the base of the girder, but also the drive part of the irrigation equipment.
- Cantilever: its length is adjustable to meet the irrigation requirements of different fields.
- Control system: consists of control cabinet, collecting ring, tower box, designated device for machine halt and electric cable, etc. to ensure the sprinkler machine working smoothly.
