Design, Construction and Performance Test of a Pedal Powered Wood Drilling Machine

This paper deals with the Design, Construction and Performance Test of a Pedal Powered Wood Drilling Machine.It does not require any specific input energy or electric power.In this paper, human power plays a vital role.This paper consists of a larger sprocket which rotates with the help of a human-powered pedal.The smaller sprocket is connected to the plane which is mutually perpendicular to the axis of the larger sprocket and is rotated by using a chain drive.The smaller sprocket is rigidly supported utilizing shaft and bearing support.A bevel gear is set with the smaller sprocket and with that another bevel gear is set at 90 degrees with that.With that bevel gear, a larger spur gear is set with the help of a shaft and then another smaller gear is meshed with that larger spur gear.With the smaller spur gear, a drill bit will be mounted for drilling.When the pedal is operated, the drill bit is rotated which will drill the wooden block material.The main aim is to reduce the human effort for drilling various materials such as wooden blocks.This paper's importance lies in the fact that it is green paper and helps us reduce our need for electricity too.Secondly, this cutter can be used and transferred in the working place easily.The machine can produce 477 rpm speed at drill bit.The machine drills Chambul, Kerosene, Shirish, Debdaru, and Almond wood samples.Moreover, this paper is very effective for electric power saving and rural area where there is no electricity.
