Reel-Type Sprinkler Irrigation Machine: Working Principle and Benefits

The reel-type sprinkler irrigation machine is driven by various methods such as water turbine, electric drive, internal combustion engine, and hydraulic systems. This article focuses on the water turbine-driven version, where pressurized water powers the turbine to rotate. The turbine, in turn, drives a winch through a speed-changing device, pulling the tractor head to move and automate the sprinkling process.

The turbine utilizes water flow and pressure to spin, transferring power to the gearbox and chain, which then powers the reel to perform winding and recovery operations. This design enables the sprinkler irrigation machine to work effectively across farmlands of different sizes, ensuring ease of operation, labor savings, and time efficiency.

Components and Their Functions

• Chassis: The chassis connects the two wheels and bears the machine's full weight. It enables movement through traction equipment. The upper part of the chassis is linked to the slewing bearing, allowing 360-degree rotation of the reel.

• PE Coiled Pipe: Made from premium materials sourced from PetroChina, the PE coiled pipe offers excellent flexibility, wear resistance, tensile strength, and impact resistance. It is used to transport water and pull the sprinkler cart for recovery.

• Reel: The reel stores and winds the coiled pipe. Driven by the water turbine’s power, the gearbox and chain transmit energy to the reel, facilitating the winding and recovery of the pipe.

• Water Turbine: This turbine uses the flow and pressure of water to rotate, which then drives the gearbox and chain to power the reel. Runnong employs the Italian CASELLA impact water turbine, directly connected to a 4-speed gearbox, making it sturdy, durable, and suitable for various sprinkler irrigation models with a long service life.

• Gearbox Device: Equipped with 4-speed adjustment, the gearbox is easy to operate and has a compact structure.

• Sprinkler Cart: The cart is pulled by the PE pipe and is recovered during irrigation, ensuring uniform backward recovery while sprinkling.

Economic Benefits of the Reel-Type Sprinkler Irrigation Machine

The reel-type sprinkler irrigation machine offers numerous economic advantages in addition to its high efficiency and convenience in agricultural production. Its unique sprinkling irrigation method and mobility make the irrigation process more effective, saving significant water resources. At the same time, it reduces labor intensity, increases productivity, and promotes the modernization of agricultural practices. In many countries, including Germany, Austria, Russia, Africa, and Central Asia, the widespread use of this system has demonstrated its excellent performance in terms of economic benefits.

• High Efficiency and Water Saving: Compared to traditional flood irrigation, the reel-type sprinkler irrigation machine significantly improves water conservation. It reduces deep seepage loss and enhances irrigation efficiency. In actual tests, flood irrigation requires 1500-3000 cubic meters of water per hectare, while the reel-type system only requires 525 cubic meters per hectare.

• Farmland Saving: Sprinkler irrigation enhances farmland utilization. Compared to surface irrigation, it saves at least 7% of farmland. Agricultural experts estimate that using the reel-type system can increase crop income by $90 per hectare for field crops and $200 per hectare for vegetable crops.

• Increased Yield from Timely Irrigation: The machine ensures stable irrigation, improving field conditions and boosting crop yields. Field crops can see yield increases of over 10% annually, while vegetable crops can experience yield increases of over 20%, significantly boosting farmers' income.

• Labor Savings: The reel-type sprinkler system saves two laborers annually compared to traditional surface irrigation, greatly reducing labor costs.

  
  

Versatility and Benefits

The reel-type sprinkler irrigation machine is highly adaptable, with strong climbing ability and ease of movement, making it ideal for small and medium-sized farmlands. Runnong’s machine not only aids in soil and water conservation but also effectively prevents deep soil seepage and salinization. The unique sprinkling method creates a favorable microclimate in the field, maintaining soil structure and preventing erosion. It is especially well-suited for irrigating strip-shaped plots ranging from 5 to 20 hectares.Learn more
