Abstract

Mini combine harvester needs a thresher that paddy and straw inserted into the thresher room. We design Hammer thresher as a part of the mini combine harvester. The research seeks to make a motorized rice thresher that paddy and straw are inserted into the thresher room. The concept of the thresher emanated from the working principles of the hammer mill mechanism, but the operating system is continuous. The result shows a rice thresher with a threshing hammer of diameter 350 mm and length 500 mm and a threshing hammer shaft of diameter 25.4 mm. We design the Components of the machine, and it makes a prototype. The power requirement of the machine was 1 HP. When the shaft thresher rotates, it will produce a beating, friction, and shaking. This process can separate the grain from rice straw and panicles respectively. The capacity of this machine is 132.1-168.0 kg of rice per hour. Therefore, the speed of shaft rotation and area of the straw chute affected threshing efficiency and rice quality.
