The present invention relates to a transmission apparatus for an agricultural work vehicle, comprising: a preceding transmission unit performing a primary speed-changing with respect to the drive generated from the engine of the agricultural work vehicle; an intermediate transmission unit performing forward/backward transmission for moving the agricultural work vehicle forward or backward in response to the drive transmitted from the preceding transmission unit, and performing a secondary speed-changing for adjusting the running speed of the agricultural work vehicle; and a trailing transmission unit performing a third speed-changing with respect to the drive transmitted from the intermediate transmission unit. In the present invention, the preceding transmission unit performs the primary speed-changing by using a preceding input shaft rotating by the drive generated from the engine and a preceding output shaft spaced apart from the preceding input shaft, the intermediate transmission unit performs the forward and backward speed-changing and the secondary speed-changing using an intermediate input shaft coupled to the preceding output shaft and an intermediate transmitting shaft spaced apart from the intermediate input shaft, and the trailing transmission unit may perform the third speed-changing by using a trailing input shaft connected to the intermediate transmission unit and a trailing output shaft spaced apart from the trailing input shaft. Therefore, the transmission apparatus for an agricultural work vehicle allows an efficient use of an installation space of the agricultural work vehicle while enabling speed-changing in a plurality of speed-changing steps.

    본 발명은 농업용 작업차량의 엔진으로부터 발생된 구동에 대해 1차 변속을 수행하는 선행변속부; 상기 선행변속부로부터 전달된 구동에 대해 상기 농업용 작업차량을 전진 또는 후진시키는 전후진변속과 상기 농업용 작업차량의 주행속도를 조절하는 2차 변속을 수행하는 중간변속부; 및 상기 중간변속부로부터 전달된 구동에 대해 3차 변속을 수행하는 후행변속부를 포함하는 농업용 작업차량의 변속장치에 관한 것이다. 본 발명에 있어서, 상기 선행변속부는 상기 엔진으로부터 발생된 구동으로 회전하는 선행입력축과 상기 선행입력축으로부터 이격되어 배치된 선행출력축을 이용하여 상기 1차 변속을 수행하고, 상기 중간변속부는 상기 선행출력축에 결합된 중간입력축과 상기 중간입력축으로부터 이격되어 배치된 중간전달축을 이용하여 상기 전후진변속과 상기 2차 변속을 수행하며, 상기 후행변속부는 상기 중간변속부에 연결된 후행입력축과 상기 후행입력축으로부터 이격되어 배치된 후행출력축을 이용하여 상기 3차 변속을 수행할 수 있다.
