Solar Powered Towable Single Tower Central Pivot Irrigator

 

Solar Powered Movable (Tow able) Center Pivot Irrigator has a Center Pivot with 180 feet to 230 feet, boom, including 20’-30’ overhang, revolving around it, in 360 degrees, delivering water like rain. Water is applied at this stationery Pivot point. Special bearing holds the Coupler with Rubber Boot avoiding leakage, while total water carrying structure is rotating. A stable ‘A’ frame, 48 Volts 100-150 Watt, Geared DC Motor, coupled to a Heavy Duty Gear Box, ultimately drives the wheels with Low Pressure Tractor Tires, at maximum speed of about 6 feet / Minute, and can be reduced to 10% with the help of setting, in order to increase the water supply.
A Hot Dipped Galvanized Pipe carries water for irrigation. Hot Dip Galvanized or Epoxy Coated structure makes the machine stable, while moving around the Central Pivot to irrigate the farm. The complete structure is transported in parts and is installed at site. Goose Necks with heavy pendants, at predefined calculated points, holds Sprinklers. The length of the pendent can be adjusted to suit the crop, crop conditions and cropping pattern. Proper selection (through computer program) of distance between the two adjutant sprinklers and the discharge through the same distributes the water evenly throughout the covered area, such that every part of the farm will get the same amount of water. Thus discharge from the sprinkler near the Pivot point is quite low as compared to next one, since it covers the smaller area. The Sprinkler at the far end spreads maximum water. The sprinklers works on Low-pressure (1.5 to 2.0 Kg /cm2) reduces the overhead on the Pump.

The yield is to the tune of 160-180% of the flood Irrigation, basically due to even distribution of Water, Liquid Fertilizers, Liquid Insecticides, Liquid weedicides which can be distributed along with water is an added feature of this machine. Water requirements reduce by 40 - 50%, thus reducing the pumping cost still further.

The use of Solar Power with storage batteries makes the machine operative, even during the nights, reducing the water requirements still further. The machine can be programmed to have any water scheduling. The Real Time Clock (RTC) in the logic controller takes care of the schedule in REAL TIME.

 
 
Machine Operation :
 

A) Auto Restart : When turned ON- If the machine STOPS due to Low Battery, thereby stopping the pump, will start the Machine & Pump again when the power resumes, i.e. battery voltage goes above high preset voltage level. Generally high preset Voltage level is set higher than the low cut-off voltage level, avoiding frequent Start /Stops of both the Machine and the Pump. This feature is really useful in remote unmanned farms, working during nights. If this feature is turned OFF, the machine will stop, when Battery Level goes Low, but has to be turned ON manually.

B) Auto Reverse : When turned ON- In case of non-circular farms, machine will oscillate between two end limits. When the machine reaches one end, it stops, changes direction and starts once again. When turned OFF, it goes to one end and Stops.

C) Wet /Dry: When put on WET- The machine starts Pump, when ON and checks for Water pressure, and continues working. In case of loss of water pressure, the machine stops, and waits till pressure is retrieved, and then starts again. This feature is most useful; when the water stops due to Pump Failure, Power failure, or Loss of water in the well or Chocked pipe. Otherwise machine just runs without putting the Pump On, not checking water pressure. This feature is useful during parking, and testing.

 
 
All the above conditions are indicated on the Bright LED display on the Front Panel, as well as on the LCD display. Battery Voltage and the Current is also indicated in the Digital Meters.

AGRICULATURE BENEFITS :

Water :
• The machine saves more than 40- 50% water. A great improvement
• Watering during night reduces water requirements, still further.
• Pumping cost is largely reduced, due to reduced Water Requirements.
• Water can be applied either in large quantity with bigger gaps or in smaller quantities, with small gaps, suitable for the particular crop,    depending on soil and atmospheric conditions.
• Appropriate sprinkler package for different crops is available.
• Water Application is adjusted with variable speed. More water - lower speed and vice versa.
• Water can be supplied any time of the year, even during extended time to rain, even after initial showers.
   (We had to do this during June 08 and August 09 at Rajgurunagar, near Pune)

The yield :
• 180-220% (80-100% above normal) yield, due to EVEN and PROPER DISTRIBUTION OF WATER, FARTILIZER, INSECTISIDES and ANTI-WEEDS
• 10-15% extra yield, with extra farm coverage, as otherwise lost in trenches, channels, furrows etc.
• Yield is faster by 1-2 weeks.
• Hilly, Uneven Portions of field are brought under Cultivation; slopes of 15-20 degrees are covered, increasing the yield still further.

Power :
• Machine works on SOLAR energy, thus no Electrical Power needed, operation is free from Power Cuts, Failures, Maintenances and Shortages.
• Solar Powered charged Storage Batteries allow the machine to be operated any time, even during nights.
• No need to carry dangerous expensive Underground / Overhead high tension expensive wires, cables at remote fields.
   Thus remote fields really become cultivable.
• Problem creating Collector Rings (Commutator) is avoided. We need Collector Rings if we use Electrical Power entry,
   and the machine moves all 360 Degrees.

Crops :

• WHEAT
• CORN
• MAIZE
• SOYBEAN
• SUNFLOWER
• POTATOS / ONIONS
• TOMATOS /GARLIC
• PEANUTS
• COTTON
• CHANA
• GHAS
• FODDER
• ALL VEGETABLES, PULSES, and MANY MORE

Benefits to fields :
• No Calcinations, helps to avoid degradation of Soil
• No Erosion of Soil, at all
• FERTILISERS in Liquid form can be applied with water.
• INSECTISIDES in Liquid form can be applied with water.
• ANTI WEED in Liquid form can be applied with water.

Other Great benefits :
• Expensive and tedious Preparation of field, with proper slopes etc. essential in the case of flood irrigation, not required.
   Sometimes this may not be possible all.
• Time bound laying and Removing of System like Drip is not required
• Laborious, troublesome and tedious, watering in HOT & SCORCHING sun is avoided, improving the operating standards of
   Farmers and Farm Labor.
• Skilled Farm Labor is not needed.
• Less susceptible to Viral Attacks, due to washing of leaves.
• Farmer can cultivate third cash crop, with saved water

The machine :
• Suitable for 3-5 ACERS, farms
• Long Life – More than 20-25 years
• Low Cost on Long Term basis
• No hidden operational cost as almost any maintenance is not needed
• Once installed the machine can be operated any time.
• Machine can climb up or down, safely 15-20 Degree slope thus very useful in any Indian conditions, bringing every inch of farm under Cultivation.
• Machine can to Towed to next neighboring fields, after one rotation, increasing the total coverage area by 4-5 times and helps to have different    cropping patterns.
• Variable Speed Drive (10-100%) makes it adaptable for convenient any water management.
• Reduction in speed increases water distribution, and vice versa
• Micro controller based operation for Highest Reliability.
• Controls the End Gun operation for watering field corners
• Real Time Clock (RTC) for precise timing control
• Suitable Alphanumeric, backlit LCD Display and LEDs indicates proper working of the Pivot.
• Programmability offers great flexibility in operation.
• Total completed running Hours in one Rotation are displayed.
• End Limit Switches make it suitable for Non Circular Fields.
• In case of wheels start churning in mud, due to excess water, Slip Timer incorporated in the machine STOPS it.
   This avoids excessive water at one location of farm, and wearing of Tires, in case of remote unattended operation.
