Development of Adjustable Elevator for Tractor Drawn Potato Digger
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 5
Abstract
Potato is the major crop grown in the country. It is a rich source of carbohydrate, used all over the country. Potato is harvested when it attains the physiological maturity. Potato harvesting is a time consuming operation, due to its various activities taken place at the same time. There is different equipment of harvesting the potato, from the field. This equipment is tractor operated, animal drawn, or hand operated. Tractor operated potato digger cum elevator is mainly used for digging and exposing potato tubers, simultaneously. The digger was found to perform very well, under varying soil condition. A potato digger cum elevator was designed and constructed, which is capable of digging potato with a minimum of injury, working on the principle of digging and elevating the soil and potatoes, simultaneously. Because of the irregular shape of a potato, many of them impact with rods, side walls and solid colds, and jump out of the conveyor web inserted windrowing them in a row. Potato jumping and damage become excessive, when vertical oscillation is vigor. Extra labor is, therefore, required for manual picking. To rectify this problem of bouncing of tubers, on the conveyor the adjustable elevator is made, at which we can adjust the elevator height two different distinct were the tubers doesn’t bounce on the elevator. It was observed that, at an elevated height of 40cm the implement is working more efficient rather than at another height, there was no damage, loss, bruising loss, cutting loss and also, there was no bouncing of the tubers on the elevator while digging. Actual field capacity is 0.30 – 040ha/h, Digging efficiency (%) 94 – 96, Cutting of tubers (%) 1.8, Field efficiency (%) 76.54.
