When the elevation control wheel 454 is driven to move by the elevation control power source 453, the elevation transmission assembly 452 is moved by the elevation control wheel 454, so that the elevation valve control assembly 451 can move by the elevation transmission assembly 452.

The lift control wheel 454 is rotatably mounted to the connection beam 12 of the frame 10 about an axis. Specifically, the elevation control wheel 454 is attached to the coupling beam 12 of the vehicle frame 10, and in this embodiment, for example, the elevation control wheel 454 is attached to a portion of the coupling beam 12 of the vehicle frame 10 that covers a PTO power transmission shaft. Preferably, the lift control wheel 454 is rotatable about a horizontal axis.

The lifting control wheel 454 can rotate forward or backward, and the lifting transmission assembly 452 moves along with the movement of the lifting control wheel 454, so that the lifting valve control assembly 451 moves along with the movement of the lifting control wheel 454, thereby controlling the height of the rice transplanting operation device 30.

The elevation control power source 453 is located below the elevation control wheel 454, and the elevation control wheel 454 and the gear of the elevation control power source 453 are engaged with each other. When the elevation control power source 453 is driven to rotate the gear of the elevation control power source 453, the elevation control wheel 454 may move forward or backward, thereby moving the elevation transmission member 452 connected to the elevation control wheel 454 to move at least a portion of the elevation valve control member 451.

For example, when the lifting control wheel 454 moves forward, the guide rod moves downward, the guide groove moves downward, and the lifting transmission assembly 452 moves along with the movement, so that the position of the lifting valve control assembly 451 is changed, and the control of the position height of the seedling planting device 30 is realized, until the movement of the guide rod exceeds the movable range of the lifting limit piece 455, the guide rod cannot move continuously, and the lifting control wheel 454 cannot move forward any more. The lift valve control assembly 451, which is coupled to the lift transmission assembly 452, also stops moving.

Further, in this embodiment, the guide bar is located behind the rotation axis of the elevation control wheel 454, the elevation transmission member 452 connected to the elevation control wheel 454 is close to the seedling planting work device 30 when the elevation control wheel 454 moves forward, and the elevation transmission member 452 connected to the elevation control wheel 454 is far from the seedling planting work device 30 when the elevation control wheel 454 moves backward.

That is, the correspondence between the turning direction of the elevation control wheel 454 and whether the seedling planting device 30 is elevated or lowered may be set as desired. For example, when the lifting control wheel 454 rotates counterclockwise, the seedling planting device 30 is raised, and when the lifting control wheel 454 rotates clockwise, the seedling planting device 30 is lowered, or when the lifting control wheel 454 rotates clockwise, the seedling planting device 30 is lowered, and when the lifting control wheel 454 rotates counterclockwise, the seedling planting device 30 is raised.

The rotation direction of the elevation control wheel 454 is controlled by controlling the rotation direction of the gear of the motor as the elevation control power source 453.

The elevation control wheel 454 is provided in a fan shape, which facilitates downsizing of the elevation control mechanism 45. It should be noted that, in the present embodiment, the elevation control wheel 454 is located in a vertical direction, that is, the elevation control wheel 454 is maintained in a standing posture and then engaged with the elevation control power source 453.

The throttle control mechanism 46 further includes a throttle actuator assembly 464, wherein the throttle actuator assembly 464 is connected to the throttle control wheel 461 and the throttle control 462, respectively. When the throttle control wheel 461 is driven to move by the throttle control power source 463, the throttle actuator assembly 464 is driven to move by the throttle control wheel 461 such that the throttle control 462 is movable by the throttle actuator assembly 464.

The throttle control wheel 461 is rotatably mounted to the connecting beam 12 of the frame 10 about an axis. Specifically, the accelerator control wheel 461 is attached to the coupling beam 12 of the frame 10, and for example, in the present embodiment, the accelerator control wheel 461 is attached to a portion of the coupling beam 12 of the frame 10 that covers a PTO power transmission shaft. Preferably, the throttle control wheel 461 is rotatable about a horizontal axis.

The throttle control wheel 461 can rotate forward or backward, and as the throttle control wheel 461 moves, the throttle actuator assembly 464 can move along with the throttle control wheel so that the throttle control member 462 moves along with the throttle control wheel to control the throttle size of the engine 511.

More specifically, the throttle control wheel 461 is a sector wheel, and preferably, the sector wheel has a sector angle of less than 180 degrees.

The accelerator control power source 463 is located below the accelerator control wheel 461, and the accelerator control wheel 461 and the gear of the accelerator control power source 463 are engaged with each other. When the throttle control power source 463 is driven to rotate the gear of the throttle control power source 463, the throttle control wheel 461 may move forward or backward, thereby moving the throttle transmission assembly 464 connected to the throttle control wheel to move the throttle control member 462.

The throttle actuator assembly 464 may include a transmission rod or a transmission cable, and the throttle control member 462 and the throttle control wheel 461 are connected through the throttle actuator assembly 464, but it will be understood by those skilled in the art that the throttle actuator assembly 464 may be arranged in various ways, and is not limited to the above examples.

The rotation angle of the throttle control wheel 461 is limited to a certain range to avoid the opening and closing angle of the throttle control 462 from being too large.

Specifically, the stopper 465 is provided with a guide groove 460, and the throttle control wheel 461 is provided with a guide rod 466, wherein the guide rod 466 is received in the guide groove 460, and the guide rod 466 can move back in the guide groove 460. The guide groove 460 has a predetermined length to limit the rotation of the throttle control wheel 461.

When the throttle control wheel 461 rotates forward or backward, the guide rod 466 moves along the guide groove 460, and since the stopper 465 is mounted on the frame, the movement range of the stopper 465 is fixed, and the movement range of the guide rod 466 that can move along the guide groove 460 is fixed. For example, when the throttle control wheel 461 moves forward, the guide rod 466 moves downward, the guide slot 460 moves downward, and the throttle actuator 464 moves along with the guide rod to change the position of the throttle control 462, thereby controlling the throttle size of the engine 511, until the guide rod 466 moves beyond the movable range of the stop 465, the guide rod 466 cannot move further, and the throttle control wheel 461 cannot move further forward. The throttle control 462, which is coupled to the throttle actuator assembly 464, also stops moving.

Further, in this embodiment, the guiding rod 466 is located behind the rotation axis of the throttle control wheel 461, when the throttle control wheel 461 moves forward, the throttle transmission assembly 464 connected to the throttle control wheel 461 is close to the throttle, and when the throttle control wheel 461 moves backward, the throttle transmission assembly 464 connected to the throttle control wheel 461 is far away from the throttle.

In other embodiments of the present invention, when the throttle control wheel 461 moves forward, the throttle transmission assembly 464 connected to the throttle control wheel 461 is far away from the throttle, and when the throttle control wheel 461 moves backward, the throttle transmission assembly 464 connected to the throttle control wheel 461 is close to the throttle.

That is, the correspondence relationship between the steering direction of the accelerator control wheel 461 and the accelerator size of the engine 511 may be set as needed. For example, when the accelerator control wheel 461 rotates counterclockwise, the accelerator of the engine 511 is larger, and when the accelerator control wheel 461 rotates clockwise, the accelerator of the engine 511 is smaller, or when the accelerator control wheel 461 rotates clockwise, the accelerator of the engine 511 is smaller, and when the accelerator control wheel 461 rotates counterclockwise, the accelerator of the engine 511 is larger.

The rotation direction of the accelerator control wheel 461 is controlled by controlling the rotation direction of a gear of the electric motor as the accelerator control power source 463.

The throttle control wheel 461 is provided in a fan shape, which facilitates downsizing of the throttle control mechanism 46. It should be noted that in this embodiment, the throttle control wheel 461 is located in a vertical direction, that is, the throttle control wheel 461 is kept in a standing posture and then is engaged with the throttle control power source 463. In this manner, it is advantageous to reduce the size of the throttle control mechanism 46 in the horizontal direction.

Further, the throttle control mechanism 46 includes an angular velocity sensor 467, wherein the angular velocity sensor 467 is disposed on the throttle control wheel 461 to obtain the rotation state of the throttle control wheel 461, so as to detect the operation state of the throttle control mechanism 46 in real time in the subsequent step.
