DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figures 1-3 , the present utility model provides a technical solution: a five - speed integrated machine, including a housing 1, inside which a five - speed shifting mechanism 2 and a power output mechanism 3 are installed. Five - speed shifting operations can be performed through the five - speed shifting mechanism 2. The five speeds are three forward gears, a reverse gear, and a neutral gear, increasing the number of gears of the transmission, effectively improving the adaptability of agricultural machinery to driving conditions, and transmitting power to the power output mechanism 3. The power output mechanism 3 is used to output power to the agricultural machinery for driving.

[0016] The five-speed transmission mechanism 2 includes a shift shaft 201, a gear shaft 202, and a reverse gear shaft 206. The shift shaft 201, the gear shaft 202, and the reverse gear shaft 206 are all rotatably connected to the inner wall of the housing 1 through a first bearing, which can reduce the frictional force when the shift shaft 201, the gear shaft 202, and the reverse gear shaft 206 rotate, making their rotation smoother. A sleeve 204 is connected to the shift shaft 201 through a spline 203, enabling the sleeve 204 to move when rotating, thereby enabling speed change operations. Three speed-changing gears 205 are fixedly connected to the sleeve 204, so that during the rotation of the shift shaft 201, the gear shifting of the gears can be achieved by controlling the meshing conditions and positions of the three speed-changing gears 205. A first gear 209, a second gear 208, and a third gear 210 are fixedly connected to the gear shaft 202, and a reverse gear 207 is fixedly connected to the reverse gear shaft 206. The third gear 210 is arranged between the first gear 209 and the second gear 208. By meshing the three speed-changing gears 205 with the first gear 209, the second gear 208, and the third gear 210 respectively, three forward gears can be formed. When not meshing, a neutral gear is formed, and when meshing with the reverse gear 207, a reverse gear is formed.

[0017] The power output mechanism 3 includes a transmission shaft 301. The top end of the transmission shaft 301 is drivingly connected to the gear shaft 202 through a first bevel gear pair 304, and the bottom end of the transmission shaft 301 is drivingly connected to a power output shaft 305 through a second bevel gear pair 303. The power output shaft 305 and the transmission shaft 301 are both rotatably connected to the inner wall of the housing 1 through a second bearing 302, which can output power. The power output shaft 305 is a double shaft, which can meet the usage requirements of agricultural machinery.

[0018] During operation, when the speed-changing gear 205 meshes with the first gear 209, a first gear is formed; when the speed-changing gear 205 meshes with the second gear 208, a second gear is formed; when the speed-changing gear 205 meshes with the third gear 210, a third gear is formed; when the speed-changing gear 205 meshes with the reverse gear 207, a reverse gear is formed; when the speed-changing gear 205 is in a non-meshing state, a neutral gear is formed, enabling the five-speed gear shifting operation. The five speeds are three forward gears, a reverse gear, and a neutral gear, increasing the number of gears of the transmission and effectively improving the adaptability of agricultural machinery to driving conditions.
