The rural development administration started supplying equipment for convenience to the farm area since 2008 as part of the improving the farm work environment. A survey was conducted to the 286 farms in Gyungbuk province for analyzing the usage status and effectiveness of convenience equipment among 3,308 farms supplied until year 2011. From the survey, it was found that the average age of the convenience equipment user age is 56.9. The elderly as well as women farmers used the equipment for work, relieving the labor shortage. Reduced physical loads (posture, dealing with heavy objects, etc.) resulted in the prevention of musculoskeletal disorders (MSDs). Regarding the evaluation of equipment, 37% experienced equipment problems, inconvenience in operating and manipulating the equipment, and other issues regarding human body size, noise and vibration. 56% of the users were satisfied. There is a need for research in the areas of part reliability, usability, and in manufacturing better equipment for convenience.

장석근,Duk Gam Woo,Tae Han Kim 한국농업기계학회 2020 바이오시스템공학 Vol.45 No.1

Purpose Harvesting chili peppers is a very difficult task in chili pepper farming. It imposes a great burden on farmers, many of whom are old. Therefore, in this study, we proposed and fabricated a motor-driven convenience for harvesting chili peppers. This equipment is suitable for use in the local chili pepper farming environment to help workers harvest chili peppers conveniently. Methods We proposed and fabricated a device by considering the physical body dimensions of farm workers and the chili pepper cultivation method. Moreover, we conducted an experiment to check the ultraviolet (UV) blocking performance of shading nets to develop a sun blocking device that protects workers from UV rays. The performance of the proposed device was evaluated through productivity verification by conducting harvesting tests and convenience analysis by using the Rapid Entire Body Assessment (REBA) tool. Results The REBA score of the proposed motor-driven convenience equipment for harvesting chili peppers was one point, and harvest quantity per hour achieved with the motor-driven convenience equipment was 21% and 7% higher than those achieved with human labor and the manually driven convenience-type equipment, respectively. Conclusions The proposed motor-driven convenience equipment for harvesting chili peppers improved the productivity of harvesting work compared to those of existing manual convenience equipment and human labor, in addition to improving work convenience.
