[0027] Working principle: When using the device, when there is a lot of dust on the smart display screen 203 and it needs to be cleaned, the motor 205 drives the threaded rod 206 to rotate. When the threaded rod 206 rotates, the slider 207 moves along the threaded rod 206 and drives the U-shaped plate 208 to move. When the U-shaped plate 208 moves, it drives the first gear 213 to move through the rotating rod 212. Since the rack 214 is engaged with the first gear 213, the first gear 213 will drive the rotating rod 212 to rotate. The rotating rod 212 will drive the active bevel gear 215 to rotate, and since the driven bevel gear 216 is engaged with the active bevel gear 215, the driven bevel gear 216 will drive the support rod 209 to rotate. At this time, the support rod 209 will drive the cleaning roller 210 to rotate, so that the dust on the smart display screen 203 can be wiped clean. When the device needs to be used on an inclined ground, the second transmission rod 309 is rotated to drive the worm 310 to rotate. Since the worm gear 308 is engaged with the worm gear 310, when the worm gear 310 rotates, the worm gear 308 will rotate accordingly and drive the turntable 303 to rotate through the first transmission rod 302. The rotation of the turntable 303 will drive the support column 304 to move, and the support columns 304 on both sides are arranged relative to each other. When the support column 304 on one side moves upward, the support column 304 on the other side moves downward. When the support column 304 moves, it can drive the support block 305 to move through the through groove 306, thereby driving the support plate 307 to move. At this time, the support plates 307 on both sides will move up and down in opposite directions, thereby driving the bottom plate 5 to tilt, keeping the tilt direction of the bottom plate 5 opposite to the tilt direction of the ground, thereby keeping the smart display screen 203 in a horizontal state, so that the device can be used on different ground surfaces; When it is necessary to spread rural culture in different directions, pull the connecting rod 404 on one side, the connecting rod 404 will drive the gear card 403 to move, and when the gear card 403 on one side moves, the movable plate 406 can be pulled to rotate through the connecting plate 407, and the movable plate 406 will drive the gear card 403 on the other side to move through the connecting plate 407, so that the gear cards 403 on both sides are disengaged from the meshing state with the second gear 402. At this time, by rotating the back panel 202, the orientation of the smart display screen 203 can be adjusted, so that rural culture can be spread in different directions, and when the angle of the back panel 202 needs to be fixed, the spring 405 will push the gear card 403 to engage with the second gear 402, so as to conveniently fix the angle of the back panel 202.
