Abstract – The main purpose of our Project is to help
available in all parts of rural Maharashtra due to financial or transportation reasons.
small scale farmers who having land area less than 5 acres by designing small scale harvester machine to harvest grains very efficiently. Our project work will focus on ease of harvesting operation to the small scale farmers for harvesting varieties of grain in less time and at low cost by considering different factors such as cost of equipment, ease of operation, time of operation and climatic conditions. This machine has cutting blades which cut crops in scissoring type of operation can cut up to two rows of crops. The power unit for this machine is Petrol engine of 14.25 HP. This power is transmitted through gear box, sprocket-chain mechanism to the cutter blades and other power requiring mechanisms for performing cutting, harvesting, and separation operation. This harvester might be the best solution for the problems faced by small scale farmers relating with availability of labors and cost of harvesting.
Thus, there is requirement of a compact and efficient combine harvester which would be more accessible and also considerably cheaper. The mission is to create a portable, user-friendly and low cost mini harvester. The idea was to create a machine which is cheap and will reduce the labour required to harvest crops. This machine has the capability and the economic value for fulfilling the needs of farmers having small land holdings. A. Conventional harvesting process: In conventional harvesting process, the crop is cut manually by labour and then this crop is get threshed by Thresher. It takes time and it is not effective as they can work only 5-6 hours in a day. Even though the small scale farmers who having land less than 5 acres, it takes two to three days to cut and harvest the crops. After plantation of crops, if proper care is not taken then non-required plants also grows with crop. So, to separate this unwanted plant while harvesting is tedious work. Aim of our project is to target small scale farmers who’s having land less than 5 acres.
Key Words: Petrol engine, cutter blade, gear box, sprocket chain. 1. INTRODUCTION Recently Maharashtra has seen a shortage of skilled labour available for agriculture. Because of this shortage, the farmers have transitioned to using harvesters. These harvesters are available for purchase but they are not affordable Recently Maharashtra has seen a shortage of skilled labour available for agriculture. Because of this shortage the farmers have transitioned to using harvesters. These harvesters are available for purchase but they are not affordable, because of their high costs. However, agriculture groups make these available for rent on an hourly basis. But the small holding farm owners generally do not require the full-featured combine harvesters. Also, these combine harvesters are not
