Introduction

For improving the productivity of ouragricultural lands it is stressed that they

must employ high technology in every

activity.

This involves the use of tractors, electrical

pumps and motors etc.

Hence if a manually operated solar speed

sprayer be designed it will prove but with avery high potential of growth.

Methodology

Auto CAD software is used fordesigning the solar seed sprayer

All the required equipment's are

purchased and the fabrication of solarseed sprayer is done manually

SPREADING INSTRUCTIONS

The opening in the hopper bottom isregulated by the control lever.

The size of the opening is determined

by the calibrated scale. Place the control lever at the desired

setting and adjust the stop bolt.


9/25

Check rate chart for suggested settingfor material type to be spread.

Width of spread depends upon the

motor speed and the weight of thematerial.

The heavier the material, the wider the

spread

SPREADING INSTRUCTIONS (Contd.)

Set seed gate opening stop for materialto be used according to the

Selected ground speed and for once or

twice over application, tighten gaff twiceover spread is used as recommended,

and area is not too large, it is advisable

to put approximately one-half of materialin hopper.

This will give an approximate check of

rate usage and will allow for adjustments



11/25

Finally close the gate and put in apredetermined amount of the material

to be spread.

Spread this and check the results. Make final adjustments to obtain

desired results stop securely on

calibrated seed plate.

TYPES OF SOWING

Hand sowing Hand sowing is the process of casting handfuls

of seed over prepared ground: broadcasting.

Usually a drag or harrow is employed to

incorporate the seed into the soil.

Open field Open field refers to the form of sowing used

historically in the agricultural context where byfields are prepared generically and left open, as

the name suggest, before being sown directly

with seed .

NEED OF SOLAR ENERGY

Developing countries in particular, facesituations of limited energy resources -especially provision of electricity in ruralareas.

There is an urgent need to address thisconstraint to the social and economicdevelopment of our country.

India faces a significant gap betweenelectricity demand and supply. Demand isincreasing at an alarming rate whencompared to supply.

According to leading Surveys, around 40

SOLAR POWER

Solar energy is the utilization of theradiation energy from the sun.

When photons strike a photovoltaic cell,

they may be reflected, pass right through,or be absorbed.

When enough sunlight is absorbed by the

material, electrons are dislodged from thematerial's atoms.

When the two surfaces are connected

through an external load, electricity flows.

TYPES OF SOLAR COLLECTORS


16/25

Concentrating solar collectors This type of solar collector consists of parabolic mirrors

that concentrate the light onto a spot or a line, where the

heat is generated.

The parabolic mirrors work like a magnifying glass.These collectors are efficient and can be produce energy

at a very high temperature 300-5000C).

Flat plate solar collectors These collectors are generally used for water heating at

moderate temperatures.

They consist of a cover made of glass or plastic and an

absorber plate with attached water tubes to heat up

water.



17/25

Evacuated tube collectors The evacuated tube collector is a non-tracking solar collector.

It consists of two concentric tubes made of borosilicate glass.

It utilizes a vacuum between the tubes in order to eliminate

conductive and convective losses. Generally they perform very well even in cold and overcast

weather.

Uncovered absorbers Uncovered absorbers are black surfaces with incorporated

water tubes. They have no additional means of retaining

heat.

They are able to yield high efficiencies near ambient

temperature (20 400 degree C). The costs are very low,

so the pay-back time is short.



18/25

Solar ponds A solar pond is a basin of water where convection is

prevented. Water is used as an insulator and as a heat

radiation barrier. Convection is prevented by a salt gradient

or by layers of transparent plastic film. The solar pond hasthe advantage that it also stores the heat.

LEADACID BATTERIES

Lead

acid batteries, invented in 1859 byFrench physicist Gaston Plant, are the oldest

type ofrechargeable battery. Despite having a

very low energy-to-weight ratio and a low

energy-to-volume ratio, their ability to supply

high currents means that the cells maintain a

relatively large power-to-weight ratio. These

features, along with their low cost, makethem attractive for use in motor vehicles to

provide the high current required

by automobile starter motors.

Leadacid batteries (under 5 kg) account for

1.5% of all portable secondary battery sales

in Japan by number of units sold (25% byprice). Sealed leadacid batteries accounted

for 10% by weight of all portable battery

sales in the EU in 2000

ADVANTAGES OF SOLAR ENERGY

Clean, renewable energy source

Solar systems are long lasting systems withwarranties that are 20-30 years

Virtually no maintenance and no recurringcosts

Ideal for remote locations that cannot be tied tothe grid

No noise or smells, solar operates totally silent

Reduce dependence on foreign oil


22/25

DISADVANTAGES OF SOLAR

ENERGY

No electricity can be produced at

night, and reduced production on

cloudy/rainy days


23/25

Results and Discussion

The device can be operated by a singleperson and an unskilled labour can

operated it.

Using this, a single person can sow seedsand cover an area of 6 hectares of land on

a songle day

Thus the design and fabrication of solar

seed sprayer has been done. Compared to manual spraying it takes only

less time and less effort.

Cost for fabricating this equipment is less.
