A Study on Improving the Performance of the Planting Device of a Vegetable Transplanter
(이앙기 성능 개선을 위한 고찰)
Abstract :
Due to
the growing demand for vegetables all year round, the use of vegetable
transplanters has become widespread in agricultural production. However, the
type of planting device used for the transplanter affects its overall
efficiency. Problems such as inaccurate planting angles and inefficiently wide
transplanting hole diameters of the planting device has limited the efficient
use of some vegetable transplanters. Our goal in this study was to improve the
efficiency of the transplanter by analyzing and modifying the linkages of the
planting device of a vegetable transplanter. Methods: Because of its widespread
usage in Korea, a linkage-type planting device was used for the experiment,
which was divided into three parts. In the first part, the physical trajectory
of the tranplanter was extracted using a CCD (charge-coupled device) camera and
analyzed. In the second part, a simulated trajectory was developed using
Recurdyn 3D software. The simulated and actual trajectories were then compared
and analyzed. In the third part, based on the results of the comparison,
improvements were made on the linkages of the transplanter and a demonstrative
exercise was conducted. Finally, in experiment B, the performance was evaluated
through an exercise using both the existing and improved planting devices.
Results: The results demonstrated that the average planting angle was improved
by 4.96 mm, the soil intrusion diameter was improved by 11.30 mm, and the
planting depth was improved by 0.68 mm. Conclusion: It was concluded that the
efficiency of a vegetable transplanter can be improved
