[0031] The transmission device 5 includes a first steering box 18, and the front and rear sides of the first steering box 18 are connected to a transmission device cover 16. The front end of the transmission device cover 16 on the front side is connected to the second steering box 24, and the rear end of the transmission device cover 16 on the rear side is connected to the third steering box 27. The first output shaft 6 is rotatably installed on the inner side of the second steering box 24, and two sets of second output shafts 13 are rotatably installed on the inner side of the third steering box 27.
[0032] The transmission device 5 drives the first output shaft 6 and the second output shaft 13 to rotate through the internal transmission structure.
[0033] The right side of the first steering box 18 is connected to a power output shaft 17 , and the right end of the power output shaft 17 is connected to the output shaft of the diesel engine 1 .
[0034] The output shaft of the diesel engine 1 drives the power output shaft 17, thereby driving the transmission device 5 to operate.
[0035] The left end of the power output shaft 17 is connected to a first bevel gear 19 , and the first bevel gear 19 is meshed with a second bevel gear 20 and a third bevel gear 22 .
[0036] The power output shaft 17 drives the first bevel gear 19 to rotate when driven by the diesel engine, and the rotating first bevel gear 19 drives the second bevel gear 20 and the third bevel gear 22 to rotate.
