When the connecting shaft 28 rotates, the second bevel gear 211 will be driven to rotate through the first bevel gear 210 at the end, and the second bevel gear 210 will be driven to rotate. The wheel 211 rotates and drives the fifth gear 212 on the inner side of the end of the rotating sleeve 23 to rotate, thereby driving the sixth gear 213 meshing with the fifth gear 212 to rotate.

The gear 24 and the rotating sleeve 23 are both rotatably connected to the outer side of the end of the first motor 21. Because the second gear 24 rotates, it will drive the rotating sleeve 23 to rotate, so that the user can turn more easily. The rotating sleeve 23 and the rolling wheel 25 can be used to assist the movement of the mechanized boat. At the same time, compared with the traditional mechanized boat, the device is less likely to get stuck with grass. When the mechanized boat is operating in the field, it often needs to face complex terrain and obstacles. The design of the rolling wheel 25 allows the mechanized boat to move freely in multiple directions, especially in a small or irregular space. It can adjust the direction more flexibly, making it easier to avoid obstacles and improve the handling efficiency. High operating efficiency. Different farmland terrains and operating requirements have different requirements on the steering and mobility performance of the mechanized tiller boat. The rolling wheel 25 with a transmission mechanism such as the second gear 24 and an overall steering function can quickly adjust the direction as needed, so that the mechanized tiller boat can better adapt to various terrains and operating conditions. The rotation and steering of the rolling wheel 25 are controlled by the first motor 21 and the second motor 26, which can simplify the operation process of the mechanized tiller boat. The driver can easily realize the rotation and steering of the inflatable sleeve 215 by controlling the start and stop of the first motor 21 and the second motor 26, reducing the need for complex operating skills and reducing the difficulty of operation.

[0034] Going further:

[0035] In an optional embodiment, a plurality of grooves 214 are provided in a ring shape on the inner side of the end of the rolling wheel 25. The grooves 214 are of a trapezoidal structure. An inflatable sleeve 215 is detachably connected to the inner side of the grooves 214. The outer side of the end of the inflatable sleeve 215 is a hollow rubber structure.

[0036] In this embodiment: the inflatable air sleeve 215 has good shock-absorbing performance, which can effectively reduce the vibration caused by the uneven ground during the driving of the motor-tillage boat, thereby protecting the various components of the motor-tillage boat, especially its precision components, and reducing the risk of damage. At the same time, the inflatable air sleeve 215 can increase the buoyancy of the device and increase the support for the motor-tillage boat. Due to its softness and deformability, the inflatable air sleeve 215 can better adapt to different ground conditions, including uneven, potholed, and puddled ground, ensuring that the motor-tillage boat can travel stably and smoothly in various terrains.

[0037] Going further:

[0038] In an optional embodiment, the outer side of the end of the inflatable sleeve 215 is a fan-shaped structure, and the interior of the inflatable sleeve 215 can be filled with gas.

At the same time, the inflatable sleeve 215 is small in size and can be quickly disassembled. When the inflatable sleeve 215 is damaged, the user can quickly disassemble and replace it. Multiple inflatable sleeves 215 jointly bear the weight of the motor tiller, which can improve the carrying capacity of the rolling wheel 25, allowing it to withstand a larger load and meet different operational requirements.

[0040] Working principle: When the user uses the device, the user can fix the device on the stern of the mechanized tiller by welding. At this time, when the user uses the device to move, the user can start the second motor 26, and the second motor 26 drives the third gear 27 on the outside of its main shaft to rotate, and then drives the fourth gear 29 meshing with it to rotate through the third gear 27, and at the same time drives the fourth gear 29 fixedly connected to the middle of the fourth gear 29 to rotate through the fourth gear 29. When the connecting shaft 28 rotates, the second bevel gear 211 is driven to rotate through the first bevel gear 210 at the end, and the second bevel gear 211 rotates while driving the fifth gear 212 on the inner side of the end of the rotating sleeve 23 to rotate, thereby driving the fifth gear 212 meshing with the fifth gear 212 to rotate. The sixth gear 213 meshingly connected to the wheel 212 rotates, and the sixth gear 213 rotates, and the scroll wheel 25 on the inner side of the end of the rotating sleeve 23 is driven to rotate. At this time, the user can move more labor-savingly through the scroll wheel 25. When the user needs to turn, the user can start the first motor 21, and the first motor 21 drives the first gear 22 on the outer side of its main shaft to rotate. When the first gear 22 rotates, it drives the second gear 24 meshing with the first gear 22 to rotate. Since the second gear 24 and the rotating sleeve 23 are both rotatably connected to the outer side of the end of the first motor 21, the rotation of the second gear 24 will drive the rotating sleeve 23 to rotate, and the user can turn more easily. 5 can realize auxiliary movement of the mechanized tiller boat. At the same time, compared with the traditional mechanized tiller boat, the device is less likely to get stuck with grass. When the mechanized tiller boat is working in the field, it often needs to face complex terrain and obstacles. The design of the rolling wheel 25 allows the mechanized tiller boat to move freely in multiple directions, especially in a narrow or irregular space, and can adjust the direction more flexibly, so that it is easier to avoid obstacles and improve the working efficiency.

The rolling wheel 25 with the transmission mechanism such as the second gear 24 and the overall steering function can quickly adjust the direction as needed, so that the mechanized tiller boat can better adapt to various terrains and working conditions. The rolling wheel 25 is controlled by the first motor 21 and the second motor 26. The rotation and steering of the motor-tillage boat can simplify the operation process of the motor-tillage boat. The driver can easily realize the rotation and steering of the inflatable sleeve 215 by controlling the start and stop of the first motor 21 and the second motor 26, which reduces the need for complex operating skills and reduces the difficulty of operation. The inflatable sleeve 215 has good shock absorption performance and can effectively reduce the vibration caused by the uneven ground during the driving of the motor-tillage boat, thereby protecting the various components of the motor-tillage boat, especially its precision components, and reducing the risk of damage.
