Description:In India around 60% of land is under cultivation. In that land lot of vegetables and fruits are cultivated. Majorly maximum amount of vegetables and fruits are wasted by mishandling of improper harvesting methods and lack of labors to harvest the crops. Still many farmers can’t get proper harvesting techniques to get their yield. In our survey we have identified major problems in harvesting process are proper machinery not available in market and also lack of awareness among most of the implements is tractor mounted. And for production also all the machines do not covered for all the crops. The structure of the harvester is a 2 stroke petrol engine with single cylinder is mounted in the left side of bottom frame and the collecting box is fixed in front of the Engine, the conveyor and blade are fixed in the front portion of the harvester. By running the machine the blades starts to dig the crops then the harvested crops are transports by conveyer and dumped into the collecting box. We designed the harvester for harvesting majorly three crops and they are (i) Allium cepa, (ii) Saccharum sinense roxb. We designed digging blade[109] with the lifting mechanism with the dimensions of 400mm length and 300mm width, thickness of the blade is about 20mm and the holes are designed in the blade are used to pour down the soils, lever[108] is used to lift the blade for recover the blade from external distractions, front wheels[107] with the 60mm thickness attached with the handle bar [101], accelerator grip[102] it helps to control the speed of the harvester, back wheels[104] with the thickness of 80mm for supporting the harvester is connected to engine by the help of chain sprocket[111], petrol tank[103] with the capacity of 2.4l has been fixed in the top of the harvester, two stroke petrol engine[105] is used to run the harvester, spur gear[106] is used to reduce the speed and convert the forward motion into reverse moment of the conveyor[110] which is designed especially for pour down the soil particles, collecting box[112] is designed with the capacity of 16.4kg is mounted in the back side of the conveyor is convenient to the angle of the conveyor and the petrol cane is designed to close the petrol and it is designed as gripped material.The main component of the harvester is the frame which carry over the every other component namely blade, conveyer, collecting box, engine, petrol tank, handle bar. The frame is mainly designed to uplift the weight of the other components. The frame is made up of carbon steel material to withstand the weight. The blade is designed to dig up the vegetables from the lower soil to upper soil. The small holes in the blade helps in removing or pouring down the extra soil or unwanted soil back to the ground. Smaller sand particles fell into the gaps present in the blade. a shaft is attached at the back side for a balance in lifting the blade. A lever is attached to the shaft for lifting the blade upward and downward. The blade can be locked with the frame by the help of lever. A conveyer roller used to lift the vegetables from the lower to upper side to pour the vegetables into the collecting box. The conveyer works in the rolling motion with the help of chains attached in the both side of the conveyer roller. The roller is mounted in an inclined angle which helps to transfer the harvested crops. The conveyer has the specific gaps that help in removing the soils with the vegetables. Heavy Sand particles fell into the gaps present in the conveyer. The collecting box fixed in the frame right next to the conveyer collects the vegetables directly from the conveyer. Conveyor conveys the crops and collected in the collecting box. , Claims:1. Our harvester can be run by petrol engine and also run by the electric motor with battery.
2. Our Digging Type Harvester is designed for minimize to labour cost and it is less in weight and size compared to the other harvesting machineries for onion and potatoes.
3. Our Blade had been designed with lifting mechanism it reduce damage.
4. Cost effective and it collects the harvested crops during harvesting
5. Conveyor, blade and collecting had been specially designed for pour downs the soil during harvesting.
