MNF exhibits some unique characteristics under the influence of external magnetic fields such as magneto-viscous effect which makes it as a promising option in the field of electronic systems cooling.
As in a rapid developing era the farming industry is in need of the equipment’s which can perform multiple tasks at a time with less effort. The smaller power tiller can perform to remove weed from field and easily handling the equipment. .Main objective of this project is to design and fabricate a mini power tiller with cultivator which is suitable for one acre to three acres of land at low cost and high efficient.
Objective of the present invention is to provide a double hollow nozzle to extrude feedstock and spray nanoparticle coating at the same time.
Multi Nozzle agricultural sprayer is designed for spraying of both insecticide and herbicide simultaneously. Insecticide is sprayed on the plants where as herbicide will be sprayed on the weed grown in between the plantation. Multi Nozzle agricultural sprayer is provided with height adjustment system which is used to change the height of the nozzle setup as per the requirement.
The idea of Seed planter is for planting of cotton and groundnut seeds. Seed hopper is designed to distribute seeds uniformly at the desired application rates. Two rows seeding can be done. Crank rocker mechanism is incorporated in the planter which would act like a seed Dibbler and sow the seed deep into the soil.
Quad machine is a multi-purpose machine which operates on single power and transmits power to many tools. The existing multi-purpose machine which operates on single power and transmits power to many tools is complicated in design and heavy weight and also it requires more space. The idea of Quad machine is to reduce space and make it as simple and concise in operation.
