[0002] Transplanting of forestry fruit tree seedlings is an important agricultural activity, which involves moving the seedlings from one place to another to facilitate their growth and reproduction. Before transplanting the seedlings, planting holes are generally dug in advance. During transplanting, the seedlings with root balls are placed in the planting holes.

[0049] In the embodiment of the present invention, the telescopic member 34 is an electric telescopic rod, and the telescopic member 34 is used to control the turntable 32 to rotate 90 degrees through a transmission connection between the rack 35 and the second transmission gear 36 .

[0050] See also Figures 13 to 16 In one embodiment of the present invention, it also includes a seedling sending component 4, which includes a rotating shell 41, a driving part 42, a sleeve, a third transmission gear 43 and a seedling releasing tube 44.

[0051] In an embodiment of the present invention, the maximum distance between the arc-shaped shell 234 and the annular shell 211 is no greater than the distance between the annular frame 12 and the arc-shaped frame 13. After rotating 90 degrees, the annular shell 211 is aligned with the center of the through hole 121. Angle sensors are installed on the surface of the center column 33 and the sleeve to monitor and control the rotation angle.

[0052] Working principle: First, a number of seedlings are placed in the seedling tube 44 in sequence, and then the mobile body 1 is used to move the transplanting mechanism 2 to the pre-dug pit, and then the driving part 42 and the third transmission gear 43 are used to control the rotating shell 41 to rotate 20 degrees or 30 degrees, so as to move the seedling tube 44 containing the seedlings to the through hole 121, and then the electromagnet 224 is controlled to be energized. When the electromagnet 224 after being energized is magnetically attached to the magnetic ring 226, the first gear ring 231 is connected to the driving gear 223 by transmission, and the first driving motor 221 is used to control the driving gear 223 and the first gear ring 231 to rotate through the driving rod 222, and the rotating first gear ring 231 is connected to the movable pin 233 by sliding by the arc guide rail 232. The arc-shaped housing 234 is driven to move along the linear guide rail 212 toward a position away from the center of the annular housing 211. At this time, the elastic band 235 is in the maximum opening state. Since the annular housing 211 is located between the through hole 121 and the arc-shaped frame 13 in the initial state, the sapling dropped from the through hole 121 enters the annular housing 211, and the arc-shaped frame 13 plays a role in supporting the sapling. Then, the electromagnet 224 is controlled to be powered off, and the reset spring 225 drives the driving gear 223 to fit the surface of the limit block 228. At this time, the driving gear 223 is connected to the second gear ring 241 in transmission. While the elastic deformation of the elastic band 235 tightens the sapling, it can drive the first gear ring 231 to rotate in the opposite direction through the arc-shaped housing 234 and the movable pin 233.

[0053] Then, the telescopic member 34 is used to control the rack 35 to be connected to the second transmission gear 36 in a transmission manner to control the longitudinal guide 31, the turntable 32 and the transplanting mechanism 2 to rotate 90 degrees with the center column 33 as the axis, and the longitudinal guide 31 is used to control the lower half or the root of the sapling to descend into the pit, and then the first drive motor 221, the drive gear 223 and the second gear ring 241 are used to control the rotation of the soil-moving part 242. The rotating soil-moving part 242 is connected to the first arcuate rack 214 and the second arcuate rack 215 in sequence by the first transmission gear 2423 to drive the plowshare 2421 to swing back and forth with the rotating shaft 2422 as the axis. The plowshare 2421 that swings back and forth and rotates with the annular shell 211 or the pit as the axis is used to send or sweep nearby soil into the pit, and then to bury the roots of the saplings. This reciprocating cycle realizes the function of automatically transplanting saplings.

[0054] In summary, (1) the present application utilizes the design of the housing component 21, the driving component 22, the seedling binding component 23 and the soil burying component 24 to cooperate with each other, which can automatically bind the seedlings and send them into the pre-dug pits on the one hand, and automatically send soil into the pits for burying while binding the seedlings in the pits, so as to prevent the seedlings from tilting during the burying process, and has the characteristics of automatic transplanting and preventing the seedlings from tilting;

[0055] (2) The design of the transplanting mechanism 2, the rotating assembly 3 and the seedling delivery assembly 4 cooperate with each other, on the one hand, the function of automatically storing and adjusting the position of the transplanting mechanism 2 is realized, and on the other hand, the seedlings to be transplanted can be automatically delivered into the transplanting mechanism 2, which has the characteristics of easy adjustment and automatic seedling delivery.
