This paper presents a complete case study for designing and manufacturing chain parts for chain conveyor use for a harvest shallot for a real. The process of harvesting shallot in Vietnam is being done manually. Mechanization, automation of the harvest process has been demanded by farmers. In the harvest shallot equipment, the chain conveyor system is used to handling the desired orbit to the packing position. Shallots are uneven in size, distributed in a certain size range. Chain conveyor systems with the chain was non-standardized were choiced. Therefore, a complete design is required to meet requirement. The design procedures are: (1) calculation of the expected loads that exert on the chain during operation, (2) selection of materials, (3) designing the different parts of the chain taking into account safety, assembly process and economic considerations. The final design was justified and validated. The chain of chain conveyor system is working properly and safety under real conditions. |
