Design and Fabrication Beach Cleaning Machine

ABSTRACT Beach pollution caused by plastic waste, bottles, seaweed, and other debris has become a serious environmental problem affecting marine ecosystems and tourism. Traditional manual cleaning methods are time-consuming, labor-intensive, and inefficient for removing waste mixed with sand. To address this issue, the present project focuses on the design and fabrication of a beach cleaning machine that can efficiently separate waste materials from sand. The machine operates using a conveyor-based mechanism combined with a perforated sieve that allows sand to fall back while collecting waste in a hopper. The system is powered by an electric motor and utilizes a chain and sprocket mechanism for power transmission. The proposed machine is designed to be simple, cost-effective, and easy to operate, making it suitable for small and medium-scale beach cleaning applications. Structural components such as the frame, shaft, bearings, and drive system are carefully selected to ensure durability and reliability under working conditions. The fabricated model was tested under practical conditions and demonstrated effective waste separation and improved cleaning efficiency compared to manual methods. This machine provides a sustainable solution for maintaining beach cleanliness, reducing human effort, and supporting environmental conservation.
