Then, the plant is planted between the two guide plates 402, so that the plant is on the moving axis of the device;

[0042] In a specific application scenario, the plant guiding module 4 is suitable for the planting link of landscape greening plants, that is, the plant guiding module 4 can limit the planting position of the plants when planting landscape greening plants, so that the plants are on the moving axis of the device, thereby avoiding the contact between the moving axis and the device due to the deviation of the plants during backfilling operations, thereby avoiding damage to the plants or causing plant death, thereby increasing the use effect of the device, and the device can also adapt to plants of different diameters.

[0049] During trenching, the trench is opened by the trenching member 7. At this time, the driving motor 910 is running, and the driving motor 910 can drive the transmission gear 909 to rotate. Since the transmission gear 909 is meshed with the driven gear 912, the driven gear 912 can drive the eccentric vertical rod 908 to rotate, and further drive the linkage rod 911 and the connecting member 904 to operate, so that the movable guide tube 905 moves back and forth inside the rotating sleeve 906, thereby causing the stabilizing side plate 903 to reciprocate and close, so as to stably compact the soil on both sides of the trench.

[0050] During the planting operation, the air pump body 406 is activated, and gas is delivered to the inside of the delivery pipe 405 through the air pump body 406, and further delivered to the inside of the communication chamber 403, so that the multiple telescopic tube chambers 404 are inflated through the communication chamber 403, and then the telescopic tube chambers 404 drive the guide plates 402 to move, so as to adjust the distance between the two guide plates 402. Then, the plant is planted between the two guide plates 402, so that the plant is on the movement axis of the device;

[0051] During backfilling, the servo motor 513 is started, and the shaft member 512 and the mounting plate frame 504 are rotated by the servo motor 513, thereby driving the connecting shaft 511 and the guide rod member 509 to move. At this time, the guide rod member 509 moves on the guide block, and as it moves, the telescopic spring rod 515 is compressed, so that the guide rod member 509 drives the two backfill guide plates 505 to approach each other and adjust to a certain distance. At this time, as the device moves, the backfill guide plates 505 will backfill the soil on both sides of the trench to the trench, and after backfilling, the compacting roller 503 will compact the people on both sides of the plant, and then as the device moves, the soil on both sides of the trench will be backfilled to the trench. The backfill pressing wheel 525 and the pressing wheel piece 526 move to the position between the two plants. At this time, the electric push rod 521 and the universal motor 520 are running, and the universal motor 520 drives the driving gear 523 to rotate. Since the driving gear 523 is engaged with the gear guide plate 501, the auxiliary wheel 524 cooperates to make the driving plate frame 522 move along with the guidance of the guide rail seat 502. At the same time, the electric push rod 521 drives the movable plate frame 527 to move, so that after the driving plate frame 522 moves, the backfill pressing wheel 525 and the pressing wheel piece 526 contact the ground to compact the soil between the two plants.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
