Center Pivot + Towable Pivot + Drivable Mobile Pivot* Lateral Move RAIN FINE (DALIAN) IRRIGATION CO.,LTD.

RAINFINE irrigation We have started to make pivot irrigation machines since 2002. We have good design of toolings and dies for mass production. We have a great team for technical development. We have efficient installation and training program. We have a good team for after sale services. Our products are mainly supplied to USA, Argentina, Australia, Brazil, Chile, Ghana, Germany, Ethiopia, France, New Zealand, Libya, Mongolia, Iraq, Paraguay, Saudi Arabic, Sudan, UAE, Zambia, Kazakhstan and Russia. Warehouse in Dalian Free Trade Zone for international market. Warehouse in Dalian factory...

The specially designed steel structure can satisfy different lengths of the machines. The smallest machine is designed only one span plus one overhang (80m in length) which is for small land operation. The heavy duty design can be extended to more than 19 spans (800m). The angles, bolts and pivot anchors are strong enough to fight windstorm. Center Pivot One end of the machine is fixed and other spans move clock wise by motor driven tires, this system is called fixed center pivot system. River water or bore well water is supplied from the fixed point, transfered through main pipes and...

Center Pivot Towing gearbox position Three or four wheels are assembled on the center part of pivot.The system can be moved from one place to another by towing main pivot point tower with a tractor.Steel cables are used to secure structure and minimalize posibility of damage.This system is called tow-able center pivot ( mobile) system.The advantage of this design is to use one machine for two or three different lands.The investment is more economical.

Lateral & Pivoting Lateral & Towable Ditch feed: - Standard lateral - Pivoting lateral (require temorary bridges) Towable lateral 2 wheels maximum 250m Hose feed lateral maximum 450m: - Standard lateral - Pivoting lateral All the machine works in linear movement by motor driven wheels to irrigate rectangle area, this system is called lateral move system or linear system. Unlike center pivot systems, where the area irrigated is dependent only on the length of the machine, lateral system area is determined by two factors: system length and travel distance. This system is mainly used for...

Control Panel 16 Wires Collector Ring Drivable control panel : • Irrigation operation / Driving operation • Tire turning / Tire turning back • Drive / Stop • Driving indicator • Emergency stop Drivable mobile pivot Two wheels on the span can be turned automatically by the motor at the center of Four wheels on the pivot point can be turned by the motor at the center of the pivot. Pivot can be driven by the motors to any place you want. All the wheels can be turned back to the irrigation position by motors after towing.

Center Pivot Rainfine 500 meters towable pivot in Kazakhstan is used in 3 different fields and is designed to tow every one or two weeks in 400mm furrow potato fields . After 4 years working, the structures and truss rods have no any distortion

Truss rods are the key parts for holding the total weight of the pivot like the bridge sling. The way of processing is very important because if the processing is not correct, the truss rods would be broken when the pivot is working and cause the falling down of the complete machine. We use high frequency electric heating system to heat the end of the steel rods and use head forging machine to forge both ends of the steel rods. We use 22mm diameter rods instead of 19mm to make them stronger than other manufacturings. You can find that the steel rod and the headed part are exactly the same...

Overall processing Yield Strength Yield strength of the rod material is 60,000 PSI ( 421.8 N/mm2) Section area: Total strength: Section area: Total strength: 22mm truss rod can stand 16 tons strength which is 34% higher than 19mm ones.

Irrigation Solution. All the steel parts are galvanized by hot dip galvanization in the top leading galvanizing plant in China. The thickness is 2.0 — 4.0 mil, which is the US galvanization standard of pivot manufacture ASTM Galvanizing process to ensure quality products.

Irrigation Solution. Pivot pipes are the most important parts of the machine. Rainfine uses 8 robots instead of workers to weld the flanges, bracket. This is the guarantee of the quality of all the pipes. On the process of manually welding, it is very difficult to control the welding speed and cause the quality Welding Speed Too much penetration even melt holes on the pipe Too less penetration even not Good penetration, strong enough

Flanges stress The best quality flanges 45°bended hammer impact test without cracking. Properly control the speed of pipe rotation and the electric current of the welding.

The Formdrill is a thermal drilling and bush-forming tool that attaches to the chuck of any high-powered drill-press. Rotating the Formdrill at high speed under high axial load (the drill-bit being strongly pushed towards the work piece) generates frictional heat.

Q The temperature of the Formdrill rapidly climbs to around 650-750 °C, while the focal area of metal reaches around 600 °C. This heat softens a small section of the metal's structure and allows the formdrill to penetrate the work piece. There is absolutely no cutting involved during the creation of the hole. Unlike a conventional drill, the strength of the work piece is not compromised by the removal of material. Instead, the heated material Forms away from its original position to form a 360° bush around the periphery of the hole. During initial stages of the Formdrill process, the heated...
