Beach cleaner

Abstract

A beach cleaner having a grate-like frame is formed with multiple longitudinal members. Each of the longitudinal members is provided with a plurality of sand pins projecting downward therefrom, and the frame is provided at its front end with the tow portion. The beach cleaner can be towed by a towing vehicle to generate on a sand area, while the sand pins scrape and collect waste scattered on the sand. The sand pins are detachably attached to the longitudinal members. The beach cleaner also includes a weight mount member, enabling the amount of burying the sand pins in a sand area to be optimized to enhance waste collection performance.
