Background

High-speed rice transplanters can be divided into conventional high-speed rice transplanters, which are generally manually variable in speed, and intelligent high-speed rice transplanters, which are generally automatically variable in speed, in an intelligent manner. With the development of the intelligent era, the intelligent high-speed rice transplanter is more and more popular with people.

Conventionally, the forward or backward movement of the conventional high-speed rice transplanter is performed by a driver operating a shift lever to control the rotational position of a valve arm of a manual transmission through the transmission action of a link and a swing arm mechanism. When a driver steps on a brake pedal of a vehicle body in the traveling process of the traditional high-speed rice transplanter, a brake arm of the vehicle body is reversely linked with the connecting rod and the swing arm mechanism, and the gear handle and the valve arm of the manual transmission are driven to return to a neutral position.

At present, the connecting rod and the swing arm mechanism are eliminated from the intelligent high-speed rice transplanter, an angular displacement sensor detects the rotation angle of the gear handle, and based on the rotation angle, a gear motor drives the pull rod to move forwards or backwards to drive the valve arm of an automatic transmission to swing, so as to control the forward or backward movement of the body of the intelligent high-speed rice transplanter. However, when the intelligent high-speed rice transplanter brakes during running, the brake arm and the gear handle are linked to return the gear handle to the neutral position, but the valve arm of the automatic transmission is not linked to the brake arm, so that the valve arm of the automatic transmission cannot return to the neutral position, that is, the gear is not reset to zero, and therefore the automatic transmission is damaged, the transmission efficiency is reduced, and the service life of the automatic transmission is shortened.

Or, for the unmanned intelligent high-speed transplanter, because the unmanned intelligent high-speed transplanter does not need to be driven manually, the gear handle is not needed to be arranged, and the mechanical transmission between the gear handle and the automatic transmission is also cancelled. However, how to return the valve arm of the automatic transmission to the neutral position when braking during driving is a problem that needs to be solved at present.

Fig. 1 to 7 show an intelligent high-speed rice transplanter according to a preferred embodiment of the present invention, wherein the intelligent high-speed rice transplanter comprises a rice transplanter body 10, an automatic transmission 20, a speed change control device 30 and a neutral-return linkage 40, wherein the automatic transmission 20 is mounted on the rice transplanter body 10, wherein the speed change control device 30 is configured to control the automatic transmission 20 to realize automatic speed change, and wherein the neutral-return linkage 40 is mounted between the rice transplanter body 10 and the automatic transmission 20 in a linkage manner. When the rice transplanter body 10 is braked during driving, the automatic transmission 20 returns to a neutral state by the linkage action of the neutral linkage mechanism 40, so that the automatic transmission 20 is prevented from being damaged.

It is understood that the transplanter body 10 of the intelligent high-speed rice transplanter may be implemented as a body of an unmanned intelligent high-speed rice transplanter, or the transplanter body 10 may be operated by a driver, such as the driver merely operates but not limited to the steering or shifting of the intelligent high-speed rice transplanter, etc. Alternatively, in another example, the rice transplanting machine body 10 of the intelligent high-speed rice transplanting machine may be implemented to be compatible with unmanned driving and manual driving, without limitation thereto.

As shown in fig. 2, further, the rice transplanter body 10 comprises a frame 11, an engine 12 and a driving system 13, wherein the engine 12 and the driving system 13 are both mounted on the frame 11, and wherein the driving system 13 can control the rotation of the engine 12 and control the running of the frame 11 such as steering or braking. The automatic transmission 20 is installed between the engine 12 and the wheels of the frame 11 to change the gear ratio or the shift position between the engine 12 and the wheels, wherein the automatic transmission 20 and the shift control device 30 are respectively provided to the rice transplanter body 10, and the automatic transmission 20 is controllably connected to the shift control device 30, wherein the shift control device 30 controls the shift of the automatic transmission 20 according to the current vehicle speed and the upcoming future vehicle speed of the rice transplanter body 10.

Preferably, the driving system 13 is implemented as an unmanned system, wherein the driving system 13 further comprises at least one driving sensor 131 and a driving processor 132, wherein the driving sensor 131 comprises a sensor for detecting the operation state of the engine, a sensor for detecting the information of the human remote control signal, at least one pair of sensors for detecting the surrounding environment of the driving vehicle, a detector for detecting the driving path, and the like, so as to respectively detect driving-related information, or detect the driving intention of the operator, and feed back the detection result to the driving processor 132, wherein the driving processor 132 controls and changes the driving state of the transplanter body 10, such as turning, accelerating, decelerating, braking, or completing the designated transplanting operation, and the like, based on the driving-related information, so as to complete the intelligent driving.

It is worth mentioning that the sensor for detecting the surrounding environment of the rice transplanter can be implemented as at least one camera module, wherein each camera module is respectively installed on the front side, the left side, the right side or the rear side of the rice transplanter body 10, and the like, and the camera module obtains the information related to the rice transplanter by shooting the surrounding environment state of the rice transplanter body 10 in real time. Or the sensor for detecting the surrounding environment of the traveling crane may be implemented as a radar device which is mounted on the rice transplanter body 10 and acquires the surrounding environment state of the rice transplanter body 10 by radar detection, etc., without limitation.

Further, the rice transplanter body 10 further comprises a brake system 14, wherein the brake system 14 is mounted on the frame 11, and when the driving sensor 131 detects brake related information requiring parking, such as an obstacle, during driving of the rice transplanter body 10, the driving processor 132 generates a brake command and feeds the brake command back to the brake system 14, wherein the brake system 14 completes braking operation, so that the rice transplanter body 10 is in a braking state.

Specifically, as shown in fig. 3A, the braking system 14 includes an actuator 141, a braking arm 142 and a braking device 143, wherein the service processor 132 is electrically connected to the actuator 141, wherein the actuator 141 is mechanically connected to the braking arm 142, wherein the braking arm 142 is connected to the braking device 143, and wherein the braking device 143 is mounted to the frame 11 to perform a braking operation.

When the rice transplanter body 10 brakes during the running process, the running processor 132 of the driving system 13 generates the braking instruction and feeds the braking instruction back to the driver 141, wherein the driver 141 drives the braking arm 142 to swing, and the braking arm 142 drives the braking device 143 to perform braking action, so that the rice transplanter body 10 brakes.

It is understood that the actuator 141 may be implemented as a motor, wherein the brake device 143 may be implemented as a hydraulic brake device, wherein the brake device 143 may be implemented as a drum brake or a disc brake, without limitation.

It should be noted that, when the rice transplanter body 10 is braked, the actuator 141 drives the brake arm 142 to swing from an initial position to a braking position by a certain stroke, so that the brake arm 142 can trigger the brake device 143 to perform a braking action in the process of swinging to the braking position to complete braking. After the rice transplanter body 10 is braked, the brake arm 142 returns to the initial position again so as to trigger the next braking action. In other words, the brake arm 142 swings back and forth between the initial position and the braking position, when the rice transplanting machine body 10 is braked, the brake arm 142 swings from the initial position to the braking position, and when the rice transplanting machine body 10 is braked, the brake arm 142 swings from the braking position to the initial position.

In a first variant of the preferred embodiment, as shown in fig. 3B, the frame 11 of the rice transplanter body 10 has a brake pedal 111, wherein the brake pedal 111 is connected to the brake arm 142, and normally, the brake pedal 111 is in a natural state and the brake arm 142 is in the initial position. When the brake pedal 111 is moved downward by a force, such as when a driver steps on the brake pedal, the brake arm 142 swings from the initial position to the braking position due to the mechanical connection, so that the braking device 143 performs a braking action. When the brake pedal 111 returns to its natural state, such as when the pedal force is removed, the brake arm 142 returns to the initial position. That is, the intelligent high-speed rice transplanter can allow the driver to artificially brake the rice transplanter body 10 by stepping on the brake pedal 111.

It is understood that the brake pedal 111 and the actuator 141 can independently control the brake arm 142 to swing back and forth between the initial position and the braking position without interfering with each other. Or the intelligent high-speed transplanter can realize unmanned intelligent braking and also can allow a driver to manually tread the brake, and the two are compatible and compatible.

Further, the automatic transmission 20 includes a transmission 21, a valve arm 22 and a safety clutch 23, wherein the transmission 21 is disposed between the engine 12 and the wheels of the frame 11 of the rice transplanter body 10 and has a certain transmission ratio to control the rotation speed of the wheels of the frame 11. When the gear ratio of the transmission 21 is changed, the transmission rate between the output shaft of the engine 12 and the wheels is changed accordingly. The speed change control device 30 is connected to the transmission device 21, wherein the speed change control device 30 controls to change the transmission ratio of the transmission device 21 according to the current speed and the upcoming future speed of the rice transplanting machine body 10, thereby completing automatic speed change. The valve arm 22 is connected to the transmission 21 and changes the gear of the transmission 21, wherein the valve arm 22 is rotated back and forth between a forward position, a neutral position and a reverse position. When the valve arm 22 is located at the forward position, the valve arm 22 controls the transmission device 21 to be in a forward gear state, and the rice transplanter body 10 can only move forward. When the valve arm 22 is located at the neutral position, the valve arm 22 controls the transmission device 21 to be in a zero gear state or a neutral state, and at the moment, the transmission device 21 stops transmitting power, so that the rice transplanter body 10 cannot drive to travel continuously. When the valve arm 22 is positioned at the reverse gear position, the valve arm 22 controls the transmission device 21 to be in a reverse gear state, and the rice transplanter body 10 can run in a reverse mode. The safety clutch 23 is provided between the engine 12 and the transmission 21 to interrupt power transmission between the engine 12 and the transmission 21, thereby enabling the transmission 21 to safely change the gear ratio.

Further, the intelligent high-speed rice transplanter automatic transmission returning to the neutral linkage method when braking in the driving process comprises the following steps: the valve arm 22 of the automatic transmission 20 is pulled back to a neutral position based on the swing of the brake arm 142 of the rice transplanter body 10.

As shown in fig. 7A, when the rice transplanting machine body 10 is braked during the forward movement, the safety clutch 23 of the automatic transmission 20 is driven to enter a disengaged state based on the swing of the brake arm 142 of the rice transplanting machine body 10; and pulling the valve arm 22 of the automatic transmission 20 back to a neutral position.

As shown in fig. 7B, when the rice transplanter body 10 is braked during the backward movement, the valve arm of the automatic transmission 20 is pulled back to the neutral position based on the swing of the brake arm of the rice transplanter body.

The linkage method further comprises the step of detecting and obtaining the driving related information; and controlling the brake swing of the brake arm 142 based on the driving-related information.

It is understood that when the safety clutch 23 is in the engaged state, the output shaft of the engine 12 is normally coupled with the input shaft of the automatic transmission 20, wherein the automatic transmission 20 is normally driven, and wherein the rice transplanter body 10 can normally drive. When the safety clutch 23 is in a disengaged state in which the output shaft of the engine 12 is disengaged from the input shaft of the automatic transmission 20, the engine 10 is in an idling state, so that the transmission 21 can safely switch gear ratios.

In other words, when the rice transplanter body 10 is driven forward, the valve arm 22 is located at the forward position, in which the transmission 21 is in the forward gear state. When the transplanter body 10 runs in reverse, the valve arm 22 is located at the reverse gear position, wherein the transmission device 21 is in a reverse gear state. When the valve arm 22 is located at the neutral position, the transmission device 21 is in a neutral state, and the rice transplanter body 10 cannot obtain power to continue running.

It will be understood by those skilled in the art that the automatic transmission 20 generally has a forward gear set, a reverse gear set, an input shaft and an output shaft, wherein the input shaft of the automatic transmission 20 is coupled with the input shaft of the generator 12, wherein the output shaft of the automatic transmission 20 is coupled with the wheels of the rice transplanter body 10, and the rotation direction of the input shaft of the generator 12 is unchanged. When the rice transplanter body 10 needs to be driven forward, the rotation angle of the valve arm 22 is positive, i.e. is located at the front gear position, wherein the forward gear set is coupled with the output shaft, so that the wheels are driven to rotate forward. When the rice transplanter body 10 needs to park in a neutral gear or slide, the valve arm 22 has a rotation angle of 0, i.e., is located at the neutral position, wherein the output shaft of the automatic transmission 20 is not coupled to the forward gear set and the reverse gear set, so that the wheels cannot be driven to rotate. When the rice transplanting machine body 10 needs to be reversed, the rotation angle of the valve arm 22 is a negative value, namely, is located at the reverse gear position, wherein the output shaft of the automatic transmission 20 is coupled with the reverse gear set, so that the vehicle is driven to rotate reversely.

Specifically, the safety clutch 23 has a clutch plate 231, wherein the engine 12 has a cam 121, wherein the clutch plate 231 is coupled to the cam 121, wherein the clutch plate 231 is rotated by a certain angle when a torque generated by the clutch plate 231 is applied with a force greater than a preset safety value, thereby disengaging the clutch plate 231 from the cam 121 to disengage the output shaft of the generator 12 from the input shaft of the automatic transmission 20, thereby entering the disengaged state.

For example, when the rotation speed of the engine 12 is reduced during high-speed running of the intelligent rice transplanter, that is, if the running speed of the rice transplanter body 10 is greater than the rotation speed of the engine 12, the clutch plate 231 is forced to rotate by a certain angle, so that the clutch plate 231 is separated from the cam 121 of the engine 12, wherein the intelligent rice transplanter continues high-speed running by using its own inertia, and when the running speed of the rice transplanter body is reduced to match the rotation speed of the engine 12, the clutch plate 231 and the cam 121 of the engine 12 automatically engage, so that the rice transplanter body 10 continues to enter a driving running state, and the like, without limitation.

In the present embodiment, the automatic transmission 20 is implemented as a continuously variable transmission or a box, that is, the transmission ratio of the transmission device 21 of the automatic transmission 20 can be continuously changed within a certain range, and hydraulic, mechanical, and electric transmissions are commonly used. The automatic transmission 20 can be classified into a variable ramp type continuously variable transmission and a CVT continuously variable transmission. The stepless speed changing box has the advantages of saving complex and heavy gear combination variable speed transmission and only using two groups of belt wheels for variable speed transmission. The automatic transmission 20 performs stepless speed change by changing the contact radius of the driving wheel and the driven wheel transmission belt, and the stepless speed change can realize continuous change of the transmission ratio, so that the optimal matching of a transmission system and the working condition of an engine is obtained, the fuel economy and the power performance of the whole vehicle are improved, the running condition of a vehicle body is improved, and the vehicle is smoother and more stable. Particularly, in the transplanting process of the rice transplanter, the shaking of the body during the speed change can be prevented through the stepless speed change of the automatic speed changer 20, so that the transplanting process is more stable and uniform, and the method is not limited herein.

Further, the return-to-neutral linkage mechanism 40 comprises a first linkage member 41 and a second linkage member 42, wherein the first linkage member 41 is arranged between the brake arm 142 and the safety clutch 23 in a linkage manner, the brake arm 142 drives the first linkage member 41 to move based on braking of the rice transplanting machine body 10 in a forward process, the first linkage member 41 drives the safety clutch 23 to enter a separated state so as to enable the valve arm 22 to return to the neutral position, the second linkage member 42 is arranged between the brake arm 142 and the valve arm 22 in a linkage manner, and the brake arm 142 drives the second linkage member 42 to move based on braking of the rice transplanting machine body 10 in a backward process, and the valve arm 22 is pulled to the neutral position by the second linkage member 42.

As shown in fig. 5A and 5B, that is, when the braking system 14 performs a braking operation during a forward traveling of the rice transplanting machine body 10, the brake arm 142 swings from the initial position to the braking position, wherein the braking device 143 performs a braking action to brake the rice transplanting machine body 10, wherein the first link 41 moves a corresponding distance with the brake arm 142 and acts on the safety clutch 23, so that the safety clutch 23 enters the disengaged state, and the safety clutch 23 forcibly pulls the valve arm 22 from the forward position to the neutral position. Then, after the rice transplanter body 10 is braked, the brake arm 142 is returned to the initial position, in which the automatic transmission 20 is in a zero gear state or a neutral state, in which the safety clutch 23 is returned to the engaged state.

As shown in fig. 6A and 6B, in the reverse running of the rice transplanter body 10, when the braking system 14 performs a braking operation, the brake arm 142 swings from the initial position to the braking position, wherein the braking device 143 performs a braking action to brake the rice transplanter body 10, wherein the second linkage member 42 moves a corresponding distance with the brake arm 142 and pulls the valve arm 22 directly from the reverse position to the neutral position. Then, after the rice transplanter body 10 is braked completely, the brake arm 142 is returned to the initial position, in which the automatic transmission 20 is in a neutral state or a neutral state.

It is worth mentioning that when the rice transplanting machine body 10 brakes during the advancing process, the second linkage member 42 does not act on the valve arm 22 although it also moves a corresponding distance, and meanwhile, the second linkage member 42 provides an avoidance space to avoid the valve arm 22 moving from the front position to the neutral position.

Specifically, the first linkage member 41 includes a first braking end 411, a first linkage body 412 and a first clutch end 413, wherein the first braking end 411 and the first clutch end 413 are integrally formed at two ends of the first linkage body 412, respectively, wherein the first braking end 411 is connected to the braking arm 142, and wherein the first clutch end 413 is connected to the lower end 2311 of the clutch plate 231 of the safety clutch 23. When the rice transplanting machine body 10 is braked during forward driving, the first linkage body 412 correspondingly moves a certain distance as the brake arm 142 swings from the initial position to the braking position, wherein the first clutch end 413 pulls the bottom end 2311 of the clutch plate 231 of the safety clutch 23, so that the clutch plate 231 of the safety clutch 23 is forced to rotate, and when the torque is greater than the preset safety value, the high end 2312 of the clutch plate 231 is disengaged from the cam 121 of the engine 12, so that the safety clutch 23 enters a disengaged state.

Further, a transmission member is provided between the high end portion 2312 of the clutch plate 231 and the valve arm 22 of the automatic transmission 20, in other words, the transmission member is drivingly connected between the high end portion 2312 of the clutch plate 231 of the safety clutch 23 and the valve arm 22. When the high end 2312 of the clutch plate 231 rotates a certain distance and disengages from the cam 121 of the engine 12, the clutch plate 231 moves the transmission a certain distance, wherein the transmission pulls the valve arm 22 from the forward position back to the neutral position. It will be understood by those skilled in the art that the transmission member is preferably implemented as a metal rod, and is not limited thereto.

The first brake end 411 is preferably connected to the brake arm 142 by a screw assembly, and when the brake arm 142 swings a certain distance, the first linkage body 412 can synchronously move a corresponding distance stroke by the connection of the screw, so that the first valve arm end 413 also moves a corresponding distance and the safety clutch 23 enters the disengaged state, and the valve arm 22 is pulled back to the neutral position.

Preferably, the first clutch end 413 has a first movable hole 4131, wherein the clutch plate 231 has a first protrusion 2313, wherein the first protrusion 2313 is disposed to relatively move within the first movable hole 4131. When the brake arm 142 is in the initial position, i.e., the rice transplanter body 10 is not braked, the first protrusion 2313 is close to one side of the first movable hole. When the rice transplanting machine body 10 is braked during forward movement, in the process that the brake arm 142 moves from the initial position to the braking position, the first clutch end 413 of the first linkage 41 pulls the first protrusion 2313 of the bottom end 2311 of the clutch plate 231 to move by a corresponding distance, so that the torque applied to the clutch plate 231 is greater than the preset safety value, and the separation state is entered.

It can be seen that, in normal driving of the rice transplanting machine body 10, the first movable hole 4131 provides an avoidance space for avoiding normal operation of the clutch plate 231 of the safety clutch 23. That is, when the rice transplanter body 10 is not braked, the first movable hole 4131 of the first clutch end 413 remains stationary during the switching of the safety clutch 23 between the engaged state and the disengaged state, in which the first protrusion 2313 of the clutch plate 231 moves within the first movable hole 4131 without being hindered by the first link 41.

Specifically, the second linkage member 42 includes a second brake end 421, a second linkage body 422, and a second arm end 423, wherein the second brake end 421 and the second arm end 423 are integrally formed at two ends of the second linkage body 422, respectively, wherein the second brake end 421 is connected to the brake arm 142, and wherein the second arm end 423 is connected to the valve arm 22. When the rice transplanter body 10 is braked during backward traveling, the second link body 422 is moved by a predetermined distance as the brake arm 142 swings from the initial position to the braking position, and the second valve arm end 423 pulls the valve arm 22 from the reverse position to the neutral position.

Further, the second brake end 421 is preferably connected to the brake arm 142 by a screw, and when the brake arm 142 swings a certain distance, the second link body 422 can synchronously move a corresponding distance stroke by the connection action of the screw, so that the second valve arm end 423 also moves a corresponding distance, and the valve arm 22 is pulled back to the neutral state from the forward position.

In this embodiment, the second valve arm end 423 forms a second movable hole 4231, wherein the valve arm 22 has a second protrusion 221, wherein the second protrusion 221 is disposed to relatively move in the second movable hole 4231. When the brake arm 142 is in the initial state, the valve arm 22 is in the reverse gear position during the reverse operation of the rice transplanter body 10, the valve arm 22 is close to one side of the second movable hole 4231, and when the rice transplanter body 10 is braked during the reverse operation, the brake arm 142 drives the second linkage member 42 to move a corresponding distance, wherein the second valve arm end 423 of the second linkage member 42 pulls the valve arm 22 from the reverse gear position to the neutral position.

It will be appreciated that when the brake arm 142 is in the initial state, the second projection 221 is located at a middle position of the second movable hole 4231 when the valve arm 22 is located at the neutral position. When the valve arm 22 moves from the neutral position to the reverse position, the second projection 221 relatively moves to a position on one side of the second movable hole 4231. When the valve arm 22 moves from the neutral position to the front position, the second projection 221 moves to the other side of the second movable hole 4231. Thus, the second movable hole 4231 of the second linkage member 42 provides an escape space for the valve arm 22 to freely move between the forward position, the neutral position, and the reverse position when not braking.

It will be understood by those skilled in the art that the positions of the first movable hole 4131 of the first clutch end 413 and the first protrusion 2313 can be interchanged. That is, the first clutch end 413 having the first protrusion 2313 and the clutch plate 231 having the first movable hole 4131 can also achieve the above objectives, which are not described herein. Accordingly, the positions of the second movable hole 4231 of the second valve arm end 423 and the second protrusion can be interchanged, which is not described herein.

In practical operation, the first linkage member 41 and the second linkage member 42 do not interfere with each other, or the movement space of the first linkage member 41 and the movement space of the second linkage member 42 are independent of each other.

The motor 34 is similar to and consistent with the motor 34 of the preferred embodiment or the first modified embodiment in structure principle, so as to be able to control and change the transmission ratio of the AT or CVT continuously variable transmission, which is not described herein again.

In other words, the future vehicle speed sensor 31 is implemented as a power sensor that is mounted to a transaxle case of the automatic transmission 20 to detect the rotation speed of the input shaft of the automatic transmission 20 to acquire information on the output power of the engine and feed it back to the controller 33. In other words, the controller 33 analyzes the future vehicle speed of the upcoming driving state of the intelligent high-speed rice transplanter based on the rotational speed of the input shaft of the automatic transmission 20.

In another embodiment, the future vehicle speed sensor 31 is implemented to acquire power information related to the control of the driving system 13B to change the output power of the engine 12, or the future vehicle speed sensor 31 is electrically connected to the driving system 13, wherein the driving system 13 controls to change the output power of the engine 12, wherein the driving system 13 sends the control information for controlling the engine 12 this time to the future vehicle speed sensor 31, and the controller 33 calculates the future vehicle speed of the upcoming driving state of the intelligent high-speed rice transplanter based on the information of the output power of the engine 12.

In other words, the driving processing module 132 is connected to the controller 33, wherein the driving processing module 132 sends the driving-related information to the controller 33, and the controller 33 obtains the future speed of the rice transplanter body 10 to be performed based on the driving-related information.

Further, based on the feedback information of the future vehicle speed sensor 31 and the vehicle speed sensor 32, the controller 33 calculates the future vehicle speed and the current actual vehicle speed of the intelligent high-speed rice transplanter, and then controls the motor 34 to control the automatic transmission 20 to change the transmission ratio, so as to automatically change the vehicle speed of the intelligent high-speed rice transplanter, so as to enter the upcoming driving state and adapt to the driving environment.

It is to be noted that the vehicle speed sensor 32 for the present preferred embodiment or the first modified embodiment is implemented to acquire the actual vehicle speed of the intelligent high-speed rice transplanter by detecting the rotation speed of the output shaft of the automatic transmission 20. However, when the output shaft of the automatic transmission 20 abnormally rotates, such as idles, the detection value of the actual vehicle speed of the intelligent high-speed rice transplanter by the vehicle speed sensor 32 may be affected, and when the output shaft of the automatic transmission 20 abnormally rotates, the detection value of the current vehicle speed detected by the vehicle speed sensor 32 is generally larger than the actual value of the actual vehicle speed of the intelligent high-speed rice transplanter, and further, when the output shaft of the automatic transmission 20 abnormally rotates, the gear ratio of the automatic transmission 20 changed by the gear ratio control device 30 may not be suitable for the driving state of the intelligent high-speed rice transplanter to be performed, and serious driving accidents may be caused.

Therefore, in order to ensure that the vehicle speed sensor 32 detects the real value of the current actual vehicle speed of the intelligent high-speed rice transplanter, the gear ratio changed by the automatic transmission 20 controlled by the gear-shifting control device 30 is ensured to be suitable for the running state of the intelligent high-speed rice transplanter to be carried out.
