Abstract

본 연구에서는 국내에서 주로 사용되는 채소 정식기를 대상으로 전체적인 작동 특성을 분석하였다. 식부장치 거동에 영향을 주는 주요 구성요소 및 동력전달경로를 파악하였으며, 식부장치의 링크 구조를 기구적으로 분석하고 3D모델링 및 시뮬레이션을 수행하였다. 이를 바탕으로 식부호퍼 극하단점의 궤적을 분석하였다. 또한 엔진회전속도 및 식부변속단수 변화에 따른 주간거리를 도출하고 필드시험을 통해 검증하였다. 주요 결과로써, 식부장치는 10개의 링크와 13개의 회전 조인트로 구성된 1 자유도의 기구이며 각 부분들은 4절 링크식으로 구성되어 있었다. 링크장치의 거동에 의해 식부호퍼는 일정한 자세를 유지하면서 연직 방향으로 묘를 심어준다. 동력은 엔진을 통해 주행부 및 식부로 전달되었으며 식부장치의 최대 및 최소 주간거리는 각각 428.97mm, 261.20mm로 나타났다.

In this study, the operational characteristics of a domestic vegetable transplanter were investigated. The main functional components and power path of the tranplanter were analyzed. The link structure of transplanting device waskinematically analyzed, and 3D modeling and dynamic simulation were performed. Based on this analysis, the trajectory of the bottom end of the transplanting hopper was analyzed. Also, the plant spacing according to the engine speed and the shifting stage of transplanting transmission was analyzed and verified by field test. As main results of this study, the transplanting device is one degree of freedom(DOF) 4-bar link type mechanism which comprises 10 links and 13 rotating joints. The transplanting hopper plants seedlings in a vertical direction while maintaining a constant posture by the links of transplanting device. The power is transmitted to both the driving part and transplanting part from the engine, and the maximum and minimum plant spacing of the transplanting device were 428.97 mm and 261.20 mm.
