마늘수확 전처리 생력기계의 개발 : A Stem-Cutter and Vinyl-Remover 줄기절단 및 비닐피복 제거기
박준걸,용상호,노광모 건국대학교 자연과학연구소 1999 建國自然科學硏究誌 Vol.10 No.1
Garlic, which is one of very popular condiments in Korea, has been raised by human power because a method of mechanized cultivation is not set up completely and machinery for garlic production is not developed yet. The objectives of this paper are to develop a machine which can be used to cut garlic stems and to remove vinyls covered on soil before harvesting. To fulfil this objectives, a prototype machine consisting of a stem-cutter and a vinyl-remover was designed. Two disk blades were used as the stem-cutter, and the vinyl-remover was composed with a vinyl-cutter and a vinyl-divider. In the 1st experiment the function of the vinyl-cutter and vinyl-divider was investigated to improve their performance, and their proper locations were determined in the 2nd experiment. Also, it is observed whether garlic stems cut by two disk b lades are properly transferred backward between them. The performance of disk blades was tested in the garlic field, by changing disk speed and height of stem cutting, and overall performance of the vinyl-divider was investigated. The results showed that the angle between the center axis of vinyl-cutter and the leading edge of two vinyl-divider should be over 29 degrees, and the leading edge of dividers should be located at the same level of soil surface, for smooth operation. Also, the proper height of vinyl-cutter is 3 cm below the leading edge of divider.

A garlic harvester attached on tractor with pulling mechanism was developed in the study, based upon a kinematical analysis and related preliminary field tests on the conventional garlic harvesting method. The harvesting efficiency of the developed harvester was more than 80% in the garlic field irrigated before harvesting. The harvesting performance of the harvester was estimated to be about 400 Pyungs/hr in the irrigated field before garlic harvesting. for proper garlic drying and collection, the harvester discharged the harvested garlic on the ground uniformly at the angles of 135˚-150˚ to its forward direction with the garlic blb's placing toward the harvester. In the field test, the forward speed of the harvester ranged approximately from 0.2 m/s through 0.8 m/s. However, it was strongly recommended that the spacing of planting garlic seeds should be standardized in the near future for increasing its harvesting efficiency.
