이러한 로터베이터는 대한민국 등록실용신안 제20-0492282호(이하 '선행기술문헌'이라 한다)에서 제안된 바 있다.Such a rotavator has been proposed in Republic of Korea Utility Model Registration No. 20-0492282 (hereinafter referred to as 'prior art literature').
선행기술문헌에 개시된 종래의 로터베이터는, 트랙터의 동력이 전달되는 동력전달부가 상부 중앙 영역에 구비되고, 양단부가 각각의 측판으로 마감된 본체와, 동력전달부와 양 측판 사이에 각각 설치된 양측의 지지프레임과, 동력전달부에 일측단이 연결된 상태로 타측단이 일측 지지프레임 즉 좌측 지지프레임을 통해 좌측의 측판을 관통하여 회전 가능하게 구비되는 기어결합축과, 기어결합축의 좌측단에 결합 고정된 상태로 회전되는 제1 스프로킷휠과 체인으로 연결되는 한편 경운축에 결합 고정된 상태로 회전되는 제2 스프로킷휠로 이루어진 기어박스가 구성된다.The conventional rotavator disclosed in the prior art literature has a main body in which the power transmission unit to which the power of the tractor is transmitted is provided in the upper center area, and both ends are finished with respective side plates, and both sides installed between the power transmission unit and both side plates, respectively. With one end connected to the support frame and the power transmission unit, the other end passes through the left side plate through one support frame, that is, the left support frame, and the gear coupling shaft provided rotatably and coupled to the left end of the gear coupling shaft. A gearbox consisting of a first sprocket wheel rotated in a rotated state and a second sprocket wheel connected by a chain while being coupled and rotated to a tiller shaft is configured.
이때, 경운축에는 다수의 경운날이 결합 고정된 상태로 설치되어 경운축에 의해 회전되면서 농지를 적정 깊이로 경운하게 된다.At this time, a plurality of tillage blades are installed in a coupled and fixed state on the tillage shaft, and the farmland is plowed to an appropriate depth while being rotated by the tillage shaft.
즉, 트랙터의 동력이 동력전달부로 전달되어 오면, 이의 동력은 동력전달부에 연결된 기어결합축으로 전달되어 기어결합축을 지지프레임 내에서 회전시키게 되고, 기어결합축에 결합 고정된 제1 스프로킷휠이 기어결합축과 같이 회전됨에 따라 체인으로 연결된 제2 스프로킷휠이 회전되며, 제2 스프로킷휠의 회전에 의해 경운축이 회전되면서 다수의 경운날이 농지를 경운하게 된다.That is, when the power of the tractor is transmitted to the power transmission unit, the power is transmitted to the gear coupling shaft connected to the power transmission unit to rotate the gear coupling shaft in the support frame, and the first sprocket wheel coupled and fixed to the gear coupling shaft As the gear coupling shaft rotates, the second sprocket wheel connected by the chain rotates, and as the tilling shaft rotates by the rotation of the second sprocket wheel, a plurality of tillage blades plow the farmland.
하지만, 로터베이터와 같은 작업기를 트랙터의 후방에 장착할 시는 트랙터 후방의 3점 링크에 로터베이터를 위치시킨 상태에서 작업자가 수작업으로 3점 링크와 로터베이터 간의 연결부에 연결핀을 끼워 고정시키고, 트랙터의 PTO 축을 로터베이터에 연결해야 하는데, 이러한 일련의 연결 작업은 매우 어렵고 번거롭게 이루어지고, 이로 인해 숙련된 작업자 2인 이상이 협력해야만 연결할 수 있는 불편한 단점이 있다.However, when a work machine such as a rotavator is mounted on the rear of a tractor, the operator manually inserts a connecting pin into the connection between the 3-point link and the rotavator while placing the rotavator on the 3-point link at the rear of the tractor, It is necessary to connect the PTO shaft of the tractor to the rotavator, and this series of connection work is very difficult and cumbersome, and due to this, there is an inconvenient disadvantage that it can be connected only by the cooperation of two or more skilled workers.
