Development of automatic fish grading machine especially for catfish with low time consumption and low capacity usage

摘要

Development of fish grading machine is a new automatic system especially for catfish for low time consumption and low capacity usage. The system is worked according to the measured sizes that want to be grade. In aquaculture sector, grading machine is very important to grade the size in order to avoid the small fishers are eaten by the big fish especially carnivore type such as catfish. This automatic machine consists of some mechanism as the main function on how the machine will be operated. This machine is created consists of linkages, DC power supply, chain and gearing system in order to operate the machine. ALGOR analysis is used to analyze and determine the critical part of the machine structure in order to know the toughness and the tensile strength of the material to be used. The tensile strength of the structure complete with 150 N loads is validated with theory and the agreement between them is achieved. The maximum value of the material steel AISI 1010 from the analysis is 26.4543 N
