[0030] The functional frame 34 is provided with a lubricating oil tank 36 at the bottom, an oil supply pump 361 is provided on the side of the lubricating oil tank 36, an oil supply pipe 362 is connected to the side of the oil supply pump 361, a transition shaft frame 363 is provided at the bottom of the lubricating oil tank 36, and a ball 37 is provided at the bottom of the transition shaft frame 363.

[0031] A rotating ring 371 is installed on the upper part of the sphere 37, and a lubricating ball 372 is nested at the bottom of the rotating ring 371. An annular groove 38 is provided at the bottom of the center of gravity adjustment chamber 3, and the rotating ring 371 is nested in the annular groove 38. A center of gravity offset detector 39 is provided at the bottom of the fifth drive motor 31.

[0032] In this embodiment, when the center of gravity ball 33 moves, the fifth drive motor 31 starts, and the fifth drive motor 31 drives the fifth rotating rod 311 to rotate. The fifth rotating rod 311 drives the structure connected to it to rotate, including the center of gravity ball 33, thereby realizing the 360° rotation of the center of gravity ball 33. During the rotation, the rotating ring 371 rotates synchronously along the ring groove 38, the lubricating ball 372 at the bottom of the ball 37 rolls in the ring groove 38, and the oil pump 361 on the side of the lubricating oil tank 36 starts intermittently, injecting lubricating oil into the ring groove 38 through the oil supply pipe 362 to reduce friction and improve rotation efficiency.

[0033] Furthermore, the sixth drive motor 32 is started, which drives the lead screw 321 to rotate. The lead screw 321 drives the slider 322 to move back and forth, thereby controlling the center of gravity ball 33 on the upper part of the slider 322 to move back and forth.

[0034] Working principle Before use, sufficient amounts of crayfish feed and crab feed are added to the two sets of aquaculture feeding boxes 5 respectively. When in use, the device is placed in the rice paddy 14 and the device is started. The four sets of steering modules 8 automatically control the device to move forward, backward, left, right and up and down. During the movement, the first stop shaft 823 and the second stop shaft 9 in the steering module 8 rotate simultaneously to drive the crayfish and crabs in and prevent debris from entering.

[0035] During the movement of the device, the fourth drive motor 11 starts in both directions, driving the fourth rotating rod 111 to rotate left and right, with a flipping angle of -90° to 90°. The fourth rotating rod 111 drives the flipping plate 112 to flip left and right to strike debris encountered during the movement, preventing it from affecting the movement of the device.

[0036] Meanwhile, the intelligent capture camera 6 at the bottom of the device intelligently monitors the bottom of the paddy field 14, intelligently analyzes whether the encountered organisms are a group of crayfish or a group of crabs, and controls the corresponding feeding box 5 to feed them. Before feeding, the hydraulic pump 10 is started, and the hydraulic pump 10 drives the hydraulic telescopic shaft 101 to retract. The hydraulic telescopic shaft 101 drives the insertion rod 113 to pass through the insertion hole 1111 and insert it into the bottom of the paddy field 14 to stabilize the device and prevent the crayfish or crabs from knocking the device over when competing for food.

[0037] To prevent the device from tipping over due to a shift in the center of gravity, a center of gravity offset detector 39 located on the bottom side of the center of gravity adjustment chamber 3 monitors the center of gravity in real time during use. When the center of gravity shifts, the center of gravity ball 33 inside the center of gravity adjustment chamber 3 begins to move and adjust the center of gravity of the device.

[0038] When the center of gravity ball 33 moves, the fifth drive motor 31 starts, and the fifth drive motor 31 drives the fifth rotating rod 311 to rotate. The fifth rotating rod 311 drives the structure connected to it to rotate, including the center of gravity ball 33, thereby realizing the 360° rotation of the center of gravity ball 33. During the rotation, the rotating ring 371 rotates synchronously along the ring groove 38. The lubricating ball 372 at the bottom of the ball 37 rolls in the ring groove 38, and the oil pump 361 on the side of the lubricating oil tank 36 starts intermittently, injecting lubricating oil into the ring groove 38 through the oil supply pipe 362 to reduce friction and improve rotation efficiency.

[0039] At the same time, the sixth drive motor 32 starts, and the sixth drive motor 32 drives the lead screw 321 to rotate. The lead screw 321 drives the slider 322 to move back and forth, thereby controlling the center of gravity ball 33 on the upper part of the slider 322 to move back and forth.
