| Summary: | To collect clams automatically and effectively on coastal beach, an automatic clam collecting device was designed. The device consists of a connecting device, a shovelling device, a conveying device, and a filtering device. The mechanical device is designed based on some of the presented devices, such as a blade with slope, a pipelined conveyor belt, planar linkage mechanisms and a ski mechanism. The connecting device is connected to the device body by bolts. The shovelling device adopts a blade with slope, which can reduce the resistance between sandy soil and the device. The transmission device adopts a conveyor belt with a two-stage reducer, which can effectively control the speed of the transmission and avoid the splash of mud. A mesh structure is used for soil filtering, which is designed with a certain slope, thus sandy soil and other impurities fall from the mesh for its own weight. The designed device for clam collecting will improve efficiency and decrease cost effectively.
