dc.description.abstractIn this research project, a mechanism was developed to remove dirt from surface of street and sidewalks. Before concept generation and selection, characteristics, types and distribution of debris on street surface was analysed to facilitate the next design phase. During conceptual design phase, different concepts were proposed using concept generation methods and the best concepts were selected. From the selected concepts, the design was developed in accordance with technical and economic criteria and general arrangement, component shapes and materials were determined. Moreover, the components and assembly were analysed and tested using SolidWorks motion analysis tools and SolidWorks simulation tool. The machine is compact and manually driven, and capable of reducing the cost of road surface cleaning work. It also prevents dust from being blown up without spraying water on the road surface during the cleaning process. At optimum working speed, it absorbs dirt efficiently without damaging the road surface. Moreover, it applies an absorbing force to the debris effectively. In its working process, the coarse debris cleaning mechanism will clean larger litters first, and then the spur gear mechanism drives the roller brush rotating at optimum speed, and thus produces negative pressure to direct the fine debris into the container. By pushing the machine, it moves the coarse and fine debris towards the dirt container. Therefore, it saves power and reduces labor force more than manually cleaning using brooms, and reduces cost when compared to employing street sweepers.en_US
