The traveling direction is the connection direction from the first sensor 81 to the second sensor 82. In this example, the direction of travel/connection direction is the direction from back to front. That is to say, when the second sensor 82 located in the front senses the seat unit 5 below, the control unit 9 will drive the vehicle body unit 1 forward.

Similarly, when the user U drives the base unit 5 to move backwards so that the base unit 5 comes under the second sensor 82 at the rear, the travel direction/the connection direction is determined by The direction to the back. That is to say, when the second sensor 82 located at the rear senses the base unit 5 below, the control unit 9 will drive the vehicle body unit 1 back.

The user U driving the first embodiment is quite simple. After completing part of the agricultural work at a certain point in a farmland, if he wants to move forward to the next certain point, that is, move the first embodiment forward. As long as the base unit 5 is intuitively driven to move forward, the power unit 3 will then drive the vehicle body unit 1 to move forward.

When the vehicle body unit 1 moves forward to a certain point, the user U can step on the supporting surface G with his feet to prevent the seat body unit 5 from moving forward as the vehicle body unit 1 moves. In this way, the base unit 5 can be reset to the bottom of the first sensor 81 relative to the vehicle body unit 1 while the vehicle body unit 1 is moving forward, and the first sensor 81 The base unit 5 is sensed to generate the sensing signal that causes the control unit 9 to stop the operation of the hub motors 31 of the power unit 3, so as to stop the first embodiment from continuing to move forward.

If the first embodiment moves too much, or when there is a U-turn to go back to deal with the previously uncompleted agricultural work, the user U can also move the base unit 5 backwards intuitively to move the first embodiment backwards. . When moving backward to a fixed point, the user only needs to step on the ground to drive the base unit 5 to move forward and below the first sensor 81 to stop the first embodiment and continue to move backward.

The advantage of the liquid supply pipe 72 in the first embodiment that is pivotally connected to the vehicle body unit 1 is that when not in use, it can be straightened as shown in FIG. When the liquid feeding pipe 72 is hung in the hook 73 as shown in Figure 4, it can not only spray liquid to crops conveniently, but also can be used as a guardrail. advantage.

Referring to FIG. 6, a second embodiment of the farming vehicle of the present invention is similar to the first embodiment, except that the second embodiment further includes an operating unit 91 provided at the front end of the frame 11. The operating unit 91 is a faucet commonly found in ordinary vehicles, and can allow the user U to manually operate the second embodiment to move forward and turn, which is convenient for the user U to move when there is no need for farming or only to move the second embodiment. When required, the second embodiment can be moved in a conventional manner.

Referring to Fig. 7, a third embodiment of the farming vehicle of the present invention is similar to the first embodiment. The difference is that the carrying unit 6 of the third embodiment is changed from a metal mesh to a rectangular seat plate. For other users to ride, it is convenient for multiple people to carry out farming at the same time, and the guide unit 4 is directly arranged on the frame of the frame 11, so that the width of the part of the frame 11 originally used to support the guide unit 4 can be changed. reduce. Compared with the first embodiment, the third embodiment has a lighter weight.

In summary, the effect of the farming vehicle of the present invention is that it can allow the user U to move the seat unit 5 with his body and control the power unit 3 to drive the vehicle body unit 1 to move back and forth, that is, it can be used by the user U to move forward and backward. The movement of the present invention is controlled in an intuitive somatosensory way, and there is no need to operate with two hands during the control, which is beneficial for the user U to free up his hands for agricultural work, which is quite convenient.
