초록
과수농가에서 수행되는 수확작업은 노동부하가 큰 주요작업으로 수확된 과실의 적재 및 운반작업에 소모되는 노동력이 크다. 본 연구에서는과수농가를 대상으로 수확된 열매의 적재 및 운반작업에 사용 가능한 간이형 보행 동력운반차를 개발하였다. 과수 농민들의 요구조건을 고려하여동력운반차의 이동속도 및 적재 용량을 선정하였다. 이에 따라, 동력운반차의 주요 구성요소를 선정하고 동력전달경로를 분석하였다. 또한, 개발된동력운반차의 성능시험을 수행하였으며 상용 소프트웨어를 활용하여 구조해석을 수행하였다. 설계된 간이형 보행 동력운반차는 전·후진이 가능하고이동속도는 최대 1 m/s이며, 최대적재용량은 500 kg이다. 본 연구에서 개발된 간이형 보행 동력운반차를 활용하면 농민들의 작업효율을 높이고신체적인 부담을 경감시킬 수 있을 것으로 판단된다.
Abstract
The harvesting work in orchard is a major work with the high labor load, and the required labor for loading and transporting fruit is huge. In this study, the working-type simple power cart that can be used for loading and transporting is developed. Moving speed and loading capacity of the power cart were selected considering of requirements of orchard farmers. Accordingly, the main components of the power cart were selected and the power transmission path was analyzed. The performance test was conducted and structural analysis was performed using commercial software. The working-type simple power cart is capable of moving forward and backward, and it can adjust the moving speed from 0 to 1 m/s using the motor controller. The maximum loading capacity is 500 kg. The developed working-type simple power cart is expected to reduce the labor load and increase the work efficiency required for the harvesting work in orchard.
