Abstract
Street sweeping using local brooms and parkers are laborious and time consuming and street sweepers are always under stresses and extreme body pains during and after work. This study therefore was aimed at creating a system for effective sweeping while minimizing associated bodily stress. A machine that simulates the traditional method of sweeping was developed and produced using locally sourced raw materials like bristles, teflon, mild steel; these materials were subjected to different common manufacturing processes and techniques. The sweeping action was achieved by principle of a portable gasoline petrol engine with shaft drive. As the rotational drive of the gasoline engine was converted to linear motion via the sprocket and chain arrangement which in turn rotates a secondary shaft with bearing attachment unto an attached portable gear box which converts the linear drive into rotary movement of the brittles dressed teflon drum for the required sweeping action. The results of the performance tests carried out showed that the machine sweeping efficiency increased with the increase in the energy input and speed thus its sweeping capacity was determined using The comparison between the developed mechanical street sweepers using gasoline engine (5.5h.p & 7.5h.p) and hand- held broom (common sweeping method) being carried out by men and women sweepers on street and major roads, depicts the variance in time taken, swept area output energy and their corresponding efficiencies. The results of this study were analyzed; we conclude that there was a significant difference in efficiencies of the machine developed and sweeping.
