摘要:
Disclosed is a power transmission device for a direct seeder, the device comprising: an operating unit having one end which is axially coupled with the side surface of a frame of the direct seeder to be capable of rotation; a plunger which is supported by means of the frame so as to push the other end of the operating unit to a tractor wheel and separate the same therefrom; a driving wheel which is installed on the other end of the operating unit to be capable of rotation and is rotated along with the wheel when coming in contact with the outer circumferential surface of the tractor wheel; a power transmission member including a driver which is installed on the other end of the operating unit to be capable of rotation so as to be co-axially formed with the driving wheel and is rotated by means of the rotary power of the driving wheel, a follower which is installed on one end of the operating unit to be capable of rotation, and a first connecting unit which connects the driver and follower so as to transfer the rotation power of the driver to the follower; and a power connecting member which transfers the rotation power of the follower to a drive shaft of the seeding unit. The plunger further comprises a hydraulic cylinder including: a cylinder body coupled with the frame through a hinge; and a cylinder rod which is forwardly and backwardly moved from the cylinder body by means of fluid pressure so as to push or pull the other end of the operating unit to or from a wheel direction of the tractor.직파기용 동력전달장치가 개시되어 있다.개시된 직파기용 동력전달장치는 상기 직파기의 프레임의 측면에 일단이 회동 가능하게 축 결합된 작동간; 상기 프레임에 지지된 채 상기 작동간의 타단을 트랙터 바퀴를 향해 밀어주거나 또는 이격시켜주는 플런저; 상기 작동간의 타단 상에 회전 가능하게 설치되어, 상기 트랙터 바퀴의 외주면에 접촉되었을 때 바퀴와 함께 회전되는 작동륜; 상기 작동륜과 동축을 이루도록 상기 작동간의 타단 상에 회전 가능하게 설치되어, 상기 작동륜의 회전동력에 의해 회전되는 구동자; 상기 작동간의 일단 상에 회전 가능하게 설치되는 종동자; 상기 구동자의 회전동력을 종동자로 전달하기 위해 구동자와 종동자를 상호 연결하는 제1 연결부재;로 이루어진 동력전달부재; 및 상기 종동자의 회전동력을 상기 파종유닛의 구동축으로 전달하는 동력연결부재;를 포함하며,상기 플런저는, 상기 프레임에 힌지 결합되는 실린더 본체와, 유압에 의해 상기 실린더 본체로부터
