Except for the rear axle box 3 and the steering linkage mechanism 6, the self structures of other parts, the connection structures and the linkage modes of the parts are common technologies in the field, and the details are not repeated.
The rear axle box 3 includes a box 31, a transmission shaft 32 disposed in the box and linked with the transmission assembly 5, two gears 33 located at the left and right ends of the transmission shaft 32 and respectively engaged with the two rear wheels 4, and two clutch mechanisms 34 located at the two ends of the transmission shaft 32 and controllably transmitting the motion of the transmission shaft 32 to the two gears 33, wherein the two clutch mechanisms 34 are both connected with the steering linkage mechanism 6.
It can be understood that the rear wheel 4 is not directly engaged with the gear 33, but a transmission gear 7 connected to the axle 41 of the rear wheel 4 is additionally provided, and the transmission gear 7 is directly or indirectly engaged with the gear 33 to realize the linkage between the rear wheel 4 and the gear 33, so that the gear 33 can drive the rear wheel 4 to rotate synchronously.
The clutch mechanism 34 has an engaged state in which the transmission unit 5 rotates the gear 33 to drive the corresponding rear wheel 4 to rotate, and a disengaged state in which the transmission unit 5 cuts off the power transmitted to the gear 33 to allow the corresponding rear wheel 4 to rotate freely; the steering linkage 6 is capable of switching one of the clutch mechanisms 34 between the engaged state and the disengaged state during steering.
While the steering linkage mechanism 6 drives the front wheels 2 to turn, the clutch mechanism 34 corresponding to the rear wheel on the turning center side is driven to perform clutch operation, so that the clutch mechanism 34 is switched from an engaged state to a disengaged state, the power transmitted by the speed change assembly 5 to the rear wheel on the turning center side is disconnected, and the paddy field working machine 100 can perform turning operation conveniently.

The linkage structure between the speed changing assembly 5 and the transmission shaft 32 is a common structure in the art and is not described herein again.
Specifically, a blind hole 331 is formed in one of the gear 33 and the transmission shaft 32, and a plug 321 matched with the blind hole 331 is formed in the other one; when the gear 33 is matched and connected with the transmission shaft 32, the inserting column 321 is inserted into the blind hole 331 along the axial direction of the transmission shaft 32, on one hand, the coaxial rotation of the transmission shaft 32 and the gear 33 is facilitated, and the running stability of the paddy field working machine 100 is enhanced; on the other hand, there is not direct spacing connection between transmission shaft 32 and gear 33, namely, transmission shaft 32 can't directly transmit the rotation motion of self to gear 33, but pass through whether clutch mechanism 34 control will the rotation motion of transmission shaft 32 transmit to gear 33 realizes clutch control, the moment of torsion of gear 33 operation obviously shortens, is favorable to reducing gear 33's production requirement and manufacturing difficulty, practices thrift the cost.
In this embodiment, the blind hole 331 is disposed on the gear 33, the plug 321 is disposed on the transmission shaft 32, and the plug 321 and the transmission shaft 32 are integrally formed, that is, the plug 321 can be regarded as a shaft end of the transmission shaft 32.
Further, the rear axle housing 3 further includes support bearings 35 disposed at two ends of the gear 33, the gear 33 is supported by the two sections of the support bearings 35, and compared with the conventional case where the gear 33 is supported by the transmission shaft 32, the pressure borne by the transmission shaft 32 can be reduced, and the support mechanisms are disposed at two ends of the gear 33, so that the overall stability of the clutch mechanism 34 is higher.
Further, each clutch mechanism 34 includes a spline housing 341 slidably connected to the transmission shaft 32, a clutch case 343 connected to an end of the gear 33 near the transmission shaft 32 and engaged with the spline housing 341 by a friction member 342, and a driving assembly 344 for driving the spline housing 341 to move along the axial direction of the transmission shaft 32 to switch the spline housing 342 between an engaged position where the clutch mechanism 34 is in an engaged state and a disengaged position where the spline housing is in a disengaged state, wherein the driving assembly 344 is movably connected to the steering linkage mechanism 6.
Specifically, the spline housing 341 and the transmission shaft 32 are slidably connected by a spline, on one hand, the spline housing 341 can synchronously rotate with the transmission shaft 32, and can drive the corresponding gear 33 to rotate when the clutch mechanism 34 is in an engaged state, and meanwhile, the spline housing 341 can move in the axial direction of the transmission shaft 32, so that the spline housing 341 can be switched between the engaged position and the disengaged position, and the operation is simple and is not prone to failure; on the other hand, the spline connection has uniform stress, the total contact area is large, and large load can be borne, and meanwhile, the spline sleeve 341 and the transmission shaft 32 have good alignment, good guidance and high precision.
The clutch case 343 is connected to the gear 33, when the clutch mechanism 34 is in an engaged state, the transmission shaft 32 rotates to drive the clutch mechanism 34 to integrally rotate, and at this time, the clutch case 343 is a part of the clutch mechanism 34 and rotates synchronously to drive the gear 33 and the transmission shaft 32 to synchronously rotate, so that the paddy field working machine 100 travels.
When the clutch mechanism 34 is in the disengaged state, the transmission shaft 32 rotates, and the spline housing 341 is rotated in synchronization only, and the clutch case 343 is kept stationary, and at this time, the gear 33 corresponding to the clutch mechanism 34 is in the free rotation state, and the rear wheel 4 meshing with the gear 33 is also in the free rotation state, and can turn left or right, so that when the paddy field working machine 100 is turned, the clutch mechanism 34 corresponding to the rear wheel on the turning center side is switched from the engaged state to the disengaged state, and the rear wheel 4 on the turning center side is in a state of advancing while rotating appropriately along with the turning, and the damage of the rear wheel 4 to the field during turning is reduced.

When the spline housing 341 is in the disengaged position, that is, the clutch mechanism 34 is in the disengaged state, the friction plates are separated from the clutch disc, and at this time, the power transmission between the transmission shaft 32 and the corresponding gear 33 is cut off by the clutch mechanism 34, the transmission shaft 32 idles, and the gear 33 is not operated and is in a freely rotating state.
Further, the driving assembly 344 includes an elastic member 345 sleeved on the transmission shaft 32 and partially located inside the spline housing 341; one end of the elastic member 345 abuts against the spline housing 341, and the other end abuts against the clutch case 343. The elastic member 345 is always in a compressed state, and when the spline housing 341 is located at the engaging position, under the driving of the elastic restoring force of the elastic member 345, the elastic member 345 applies a force to the spline housing 341 to move in a direction away from the clutch case 343, so as to enhance the abutting force between the friction plate and the clutch disc, thereby increasing the frictional force therebetween, and further facilitating the power transmission between the transmission shaft 32 and the gear 33.
The elastic member 345 is further compressed when the driving assembly 344 drives the spline housing 341 to switch from the engaged position to the disengaged position, and the spline housing 341 automatically switches from the disengaged position to the engaged position under the elastic restoring force of the elastic member 345 after the driving assembly 344 cancels the driving force applied to the spline housing 341.
Specifically, the elastic element 345 is a spring sleeved on the transmission shaft 32.

While the steering linkage 6 drives the front wheel 2 to turn, the corresponding rotating body 346 is driven to rotate by the connecting piece 348 of the clutch mechanism 34 corresponding to the rear wheel at the turning center side, so that the eccentric piece 347 is driven to rotate, and the spline housing 341 is driven to switch from the engaging position to the disengaging position; after the turning is completed, the steering linkage mechanism 6 returns to the original position to drive the eccentric member 347 to return to the original position, and meanwhile, the elastic member 345 drives the spline housing to be switched from the separation position to the engagement position, so that the rear wheel on the turning center side and the transmission shaft 32 can synchronously rotate, and the normal running of the paddy field working machine 100 is realized.
Specifically, in this embodiment, the eccentric member 347 includes a rotating shaft 3471 protruding from the upper end of the rotating body 346 and deviating from the center of the rotating body 346, and a bearing 3472 sleeved on the rotating shaft 3471 and acting on one end of the spline housing 341 away from the clutch case 343, and when the rotating body 346 rotates, the bearing 3472 is driven to perform eccentric motion, so that the bearing 3472 drives the spline housing 341 to switch between the engaging position and the disengaging position.
