[0038] The working principle of this utility model is:

[0039] Photovoltaic panel 1 3-3 and photovoltaic panel 2 3-4 can generate electricity and store the electricity in the battery box 3-1 to provide power for the device. Through solar energy, the robot can be self-sufficient in terms of the amount of electricity it needs, which reduces power consumption, increases battery life, and improves the utilization rate of solar energy, thus achieving the purpose of energy saving.

[0040] The device is driven to move by a plurality of wheels.

[0042] The motor 2 4-4-3 is energized to drive the rotating wheel 4-4-4 to rotate. The rotating wheel 4-4-4 drives the sliding rod 4-4-6 to slide inward along the sliding slot frame 4-4-2 through the arc hole and the convex column, thereby driving the fan-shaped baffle 4-4-5 to close. At this time, the fan-shaped baffle 4-4-5 is closed into a circle to block the hollow telescopic tube 4-3 so that the fertilizer does not flow out. The above steps can be reversed to make multiple fan-shaped baffles 4-4-5 expand and separate outward for fertilization, which can ensure the accuracy of fertilization and avoid fertilizer blockage.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
