1. A transmission apparatus of an agricultural working automobile, comprising:
a first gear-shifting part which performs gear shifting to adjust a speed of an agricultural working automobile; and
a second gear-shifting part which performs gear shifting to adjust the speed of the agricultural working automobile,
wherein,
the first gear-shifting part includes a main gear-shifting part which performs first gear shifting to adjust the speed of the agricultural working automobile,
the second gear-shifting part includes a sub gear-shifting part which performs second gear shifting on a driving power transmitted from the first gear-shifting part,
the main gear-shifting part includes a main gear-shifting drive mechanism which performs the first gear shifting and a main gear-shifting output mechanism connected to the sub gear-shifting part,
the main gear-shifting drive mechanism includes a main gear-shifting input mechanism and a plurality of main gear-shifting drive gears,
the main gear-shifting input mechanism is rotated by a driving power provided from an engine of the agricultural working automobile,
the main gear-shifting drive gears are idly coupled to the main gear-shifting input mechanism,
the main gear-shifting output mechanism includes a plurality of main gear-shifting output gears connected to the main gear-shifting drive mechanism, and a main gear-shifting output member coupled to the main gear-shifting output gears,
the sub gear-shifting part includes a sub gear-shifting connection mechanism connected to the main gear-shifting drive mechanism, a sub gear-shifting drive mechanism which performs the second gear shifting, and a sub gear-shifting input mechanism connected to each of the sub gear-shifting connection mechanism and the sub gear-shifting drive mechanism,
one side of the main gear-shifting output member is coupled to the main gear-shifting output gears and the other side of the main gear-shifting output member is coupled to the sub gear-shifting drive mechanism to implement a first power transmission path,
one side of the sub gear-shifting connection mechanism is coupled to one main gear-shifting drive gear of the main gear-shifting drive gears, and the other side of the sub gear-shifting connection mechanism is coupled to the sub gear-shifting input mechanism to implement a second power transmission path, and
the sub gear-shifting drive mechanism performs the second gear shifting using one driving power selected from a driving power transmitted through the first power transmission path and a driving power transmitted through the second power transmission path.
