Design of Bamboo Splitting Machine Using Chain Drive

Abstract

In the rural community, bamboo splitting activities were done by using traditional tools called sickle that exposed the operators to harmful damages. This study was deal with the utilization of modern technology related to the field of forest tree processing machinery, particularly a bamboo splitting machine. The project was to design and analyze of bamboo splitting machines used for the construction of small houses, traditional house equipment, and fences in the rural and urban areas of Ethiopia. Different data collection techniques (tools) were used, to understand the current problems of bamboo splitting activities and the need for this machine. The design feature was considering the geometrical components, operating power identification and determination, and stress, forces, and deformation analysis of each part. Pro-Engineer software was used for part details and assembly drawing. Materials were selected based on availability, cost, functionality, and durability. The splitter machine was functioning intermittent feeding through a chain drive comprising a motor, a tool rest, a cutter-head, and blades or cutting die, whereby a guide rail is arranged on the side of the tailstock. According to the new design and development, the bamboo splitting machine can perform splitting bamboo culm up to 2.5 m in length and 120 mm in diameter with different strap sizes. The new machine is better efficient than the existing one that avoids tediousness, reduces operation time and avoids the irregular surface of bamboo.
