Bicycle Powered Portable Irrigation Pump

The equipment was specifically developed for use in rural areas having marginal land holding and inaccessibility of electricity.

The average flow rate was varied between 27 to 40 l/min for different pumping head of 0 to 5 m.

The maximum flow rate was obtained as 40 l/min at zero head while the minimum average flow rate of 22 l/min was obtained at 5 m head.

Its main advantage over existing technology is its mobility which means that it is suitable for irrigating the farm lands of uneven terrains and with where canal irrigation is impossible. Slide3

Bicycle powered portable irrigation pumpSlide4

The developed bicycle powered pump could be an ideal pumping system for marginal land holding in those areas, where an electricity supply is inaccessible.

Based on the results, the pumping head and flow rate were found to be directly related with the input power generated by human being through pedaling of bicycle.

The performance of the pump depended on the subject and the amount of effort put in.

Different

pedallers

generate different power depending upon their strengths.

The developed pump could be utilized successfully up to a pumping head of 4-5 m. Slide5

Modified Biogas Plant for Temperate Region

The floating drum type biogas plant of 3 m

was selected for temperate climate.

The biogas plant was designed for an average retention period of 40 days.

The slurry consists of 20% of total solid content of fresh cattle manure and mixed with water in 1:1 ratio.

The volume of gas holder was designed as 70% of capacity of plant.

The column was designed for the maximum load equal to the total weight of the gas holder and weight of guide frame.

The backfilling between wall and pit-side was done with straw, husk and plant residues. Slide6

To maintain desired temperature in the digester, a poly-house type structure was constructed on floating drum type biogas plant.

The ambient temperature, temperature inside

polyhouse

and temperature inside digester (covered with

polyhouse

) was recorded on daily basis.

Based on the results available, it was observed that from

June to August

, biogas production is normal without additional inputs.Slide9

From

March to May

and September to November, biogas can be produced successfully with the help of insulation like polyhouse

type structure on a plant.

While in remaining months viz.

December to February

, additional heat in form of mixing hot water as input is required for biogas production in the region.

The modified biogas plants works successfully whole the year for production of biogas.

T

he modified biogas plant was installed at 06 different locations of farmer’s house.

More than 100 farmers were provided trainings. Slide10

Foot Operated Maize Cob Sheller

A low cost and highly efficient foot operated maize

sheller

was designed, developed and evaluated for its performance and techno-economic feasibility in comparison to three existing methods of shelling.

Average output of 24.27 kg/h and shelling efficiency of 97.32 % were obtained.

Maximum

detachment of grains with minimum damage of 5.15 % were observed at a moisture content of 16-18 %.

The

designed maize

sheller

was techno economically feasible with an operating cost of $1.24 /

qtl

. as compared to $1.68, 2.45 and 3.71 per quintal for the beating method, horizontal maize

sheller

and octagonal maize

sheller

, respectively.

The net present value, benefit cost ratio, break-even point and pay back period were $ 60, 2.07, 8.75 q and 4 months, respectively, of the designed

sheller

Pipe Bending Machine

In the State of J&K where the peoples faced with the issue of livelihood due to declining land holdings and rising cost of production, protected cultivation through greenhouse technology is a good option under the prevailing circumstances.

The results have shown that the productivity can be enhanced by 5-10 times under green house conditions of protected environment.

Efforts have been made to promote protected farming to increase cropping intensity, productivity and improve product quality for more income and employment.

Off season produce can fetch greater net returns, achieving greater degree of food and nutritional security and widen livelihood opportunities for the rural people. Slide13

A simple intervention made by resulted in development of more than 300 low cost

polyhouses

, semi controlled polyhouses and Hi-Tech

polyhouses

in farmers fields, government farms and agricultural entrepreneurs farms.

Innovations like pipe bending machines have resulted in greatly increasing the capacity and efficiency in fabrication of these structures.

The pipe bending machine is useful for bending circular and square Mild steel and G.I. Pipe of up to 38.1 mm (1.5”) size.Slide14

Removing of outer shell of walnut is very difficult by hand.

However it is being done manually by using a sharp knife with a production rate of 25-30 kg/hr, which is time consuming and laborious.

Presently few imported machines of large capacities are available with Industrialist but these machines are not economical viable for small and marginal farmers.

In present research work, a motorized walnut

dehulling

machine based on the principle to shear-off the husk of the dry walnut by shearing force was developed and evaluated, with rotational speed and number of heaping days being optimized to make the best quality of hulling process.Slide17

The results indicate that increasing the rotational speed, increases the amount of walnuts hulled but that the percentage of damaged nuts also increases.

Similarly hulling efficiency also increases with number of heaping days before hulling but the quality of fruit decreases with increase in the number of heaping days after harvest.

The hulling capacity of the developed machine was obtained as 350 kg/h with hulling efficiency of 93 % at optimum rotational speed of 350 rpm. Slide18

Apricot Harvesting NetSlide19

Fruit harvesting net with Mechanical Shaker/Vibrator is very promising equipment for fruit grower.

The harvesting capacity is 300-350 kg/h against 15-17 kg/h by traditional methods.

Fruits harvested by using the developed net results in negligible bruising and fetches about 20-30 % higher prices than the traditional method of harvesting.

Also, the quality of the dried fruits is retained without damage and dirt.

The operating cost of harvesting is

Rs

. 1.0 -1.40/ kg against

Rs

. 2.0-3.3/kg with traditional harvesting. Cost of the device is
