[0016] In summary, the present invention includes the following beneficial technical effects:

[0017] 1. The present invention provides components such as a soil pressing block, an outer cylinder, concentric rings and a telescopic soil pressing structure. After the tree pit is dug, the outer cylinder is controlled to rotate to the top of the tree pit, and the soil pressing block is pushed into the tree pit through a power telescopic rod B. Then, the seedlings to be planted are placed from the concentric rings into the tree hole. The concentric rings rotate and drive the soil pressing block to rotate around the axis of the tree pit. At the same time, the soil pressing block gradually moves upward and continuously moves upward while rotating around the axis of the tree pit. The soil pressing block continuously and uniformly compacts the soil pushed into the tree pit around the axis of the tree pit while moving, thereby increasing the degree of soil compaction and increasing the firmness of the tree after planting.

[0018] 2. The present invention arranges components such as a reciprocating wire drum, a round rod, a twisting inner grooved drum and a synchronous wire drum. The round rod enables the reciprocating wire drum to move up and down only relative to the twisting inner grooved drum, and the center outer prism rod and the center inner grooved drum enable the soil pressing block to move up and down only relative to the twisting inner grooved drum. During the rotation of the twisting inner grooved drum, the reciprocating wire drum is engaged with the reciprocating wire drum in relative rotation, thereby driving the reciprocating wire drum to move upward, and then the reciprocating wire drum drives the synchronous wire drum, the center inner grooved drum and the soil pressing block to move upward. At the same time, when the twisting inner grooved drum rotates, the synchronous wire drum is driven to rotate relative to the reciprocating wire drum through the outer prism, so that the synchronous wire drum drives the soil pressing block to move upward and reciprocately with the reciprocating wire drum as a whole while moving upward, thereby continuously compacting the soil below.

[0019] 3. The present invention provides components such as an offset ring, a bulldozer threaded barrel and a prying plate. When the concentric ring rotates, the bulldozer threaded barrel drives the offset ring and the prying plate to rotate. During the rotation of the prying plate, the soil outside the tree pit is gradually pushed into the tree pit. At the same time, the lower inner gear ring engages with the bulldozer gear that rotates with the concentric ring, drives the bulldozer threaded barrel and the offset ring to rotate and engage relative to each other, continuously pushing the offset ring downward, so that the prying plate continuously moves downward while rotating around the tree pit, and continuously pushing the soil outside the tree pit into the tree pit.

[0020] 4. The present invention provides elastic limiting plates, arc-shaped telescopic rods, balls and other components, so that the saplings to be planted are pushed between two vertical poles with gaps into between multiple elastic limiting plates. The arc-shaped telescopic rod has a tendency to open the two connected vertical poles. Then, when the sapling moves downward, the balls come into contact with the tree trunk, reducing the damage to the bark caused by the elastic limiting plates. Multiple elastic limiting plates support the tree trunk on all sides, effectively preventing the tree trunk from tilting during planting. BRIEF DESCRIPTION OF THE DRAWINGS
