In a field harvester and trimmer for root crops having foliage tops growing from the crowns of the crop to be harvested and trimmed, such as large bulbous onions, turnips, parsnips and rutabagas.
This project is intended to discuss the design leaf, root cutting and sorting machine. Tomato Sorting Machine is a machine used to effectively sort the onion on Size based sorting. This machine can be used for the agricultural purpose and it can be also employed in the food industries.Leaf, root cutting and sorting machine will sort the onion in three grades based on their size that is Small, Medium and Large. Leaf, root cutting and sorting machine works on belt and pulley arrangement. Onion are fed through feeding tray into the machine
India is world's second largest Onion harvested.But yet Farmers processes onion by hand labor after harvest to remove the leaves and roots. This operation is referred to as topping which is time consuming and They Can't afford New Techniques Because of the cost of Appraisal Our Motive is to supply them with effective and efficient method for harvesting to reduce human effort without damaging the onion, Efforts to date have all been in the direction of large and expensive machinery and none of these has as yet been perfected so as to reach the market. A Prototype aims at separating onion bulb from rest of the crop using two rollers and cutters to cut onions which can be collected in bags using chain conveyer for further processing or packaging
The heart of the invention is in the topping mechanism itself which generally involves the following parts and steps of operation. The onion containing both roots and leaves is fed into a drum by hands. The drum grips the onion by the leaves in the vicinity of the neck of the onion and holds the body and root in a position while it is being moved along on the drum. At the discharge end of the drum cutting blades separates the leaves from the onion and sort according size.
