본 연구는 국내의 답리작 랩-사일리지 및 볏짚 등의 대형 원형 베일을 한번의 작업으로 세절 및 급여 할 수 있는 원형 베일 조사료용 트랙터 견인형 세절-급여기 개발에 관한 것으로 외국의 건초나 목초와 달리 절단저항이 큰 볏짚 등의 원형 베일까지 원활히 세절 할 수 있도록 하기 위하여 세절 메카니즘을 개발하고, 여기에 적합한 세절 부품들을 설계제작 하였으며, 그 성능을 테스트하였다. 그 결과를 요약하면 다음과 같다.Not many types of roughage cutters have been introduced in Korea so far. However, those machines could not satisfy farmers to cut rice straw or barley wrap-silage properly. There were two major obstructing factors to cut roughages; roughages were too stuff to be cut and round bale was too firm to be unbaled.
In order to solve this problem, a tractor attached cut-feeding machinery for the round baled roughage was developed for dairy and beef cattle farm in Korea.
For the study, a series of tests were performed and acquired data were analyzed by using the several imported roughage cutters, which have been already introduced in dairy farm in Korea. And, a prototype of forage cutter was selected, analyzed, designed and manufactured to develop a tractor attached roughage cut-feeder for round bale. Also, the prototype machinery was tested, modified and improved through revising model. As a result, a tractor attached roughage cut-feeder for round bale was manufactured. In order to evaluate the performance of the model machinery. a series of test were performed by the prototype machinery both at the plant and field. The model machinery developed satisfied in both power requirement and cutting capacity.
As a conclusion, one of the obstacles against feeding the round baled roughage in the korea cattle farm can be eliminated by developing the tractor attached round baled roughage cut-feeder.
