Abstract:
Agriculture is consider to be backbone of Pakistani economy, it is estimated that 19.5% of Gross Development Product employing a large quantity of the workforce to provide raw materials for many regions of value-added. Hence it plays a tremendous role in national development, security of food and shortage alleviation. Instantaneous progress in city areas in Pakistan depicts that the need for important fresh products such as fruits, vegetables, dairy products, and the meat is increasing.
In this research work, the utility model reveals a portable and safe chaff cutter machine which consists of a feed channel, a pair of feed roller, one shear blade, three cutting blades, a discharge channel, an electric motor, power transmission unit, an idler frame and a casing. Electric motor transmits power to the shaft of cutting blades and these blades act tangentially to the shear blade. The upper feed roller shaft transmits power to lower feed roller shaft through spur gears. These spur gears mesh and generate opposite rotation to each other and this rotation helps the chaff to move forward. The utility model has the advantage of good automatic feed effect, reduces the number of workers, lightens labor intensity, improves the efficiency, avoids personal injuries, and short crops and long crops can be all fed simultaneously.
