[0035] In some embodiments, the sling 4 further includes a reinforcing rod 44, one end of which is connected to the sling 41, and the other end of which is connected to both the first stabilizing rod 35 and the second stabilizing rod 36. The reinforcing rod 44 connects the sling 41 and the first stabilizing rod 35 and the second stabilizing rod 36, which can enhance the connection strength between the sling 41 and the connecting rod 33, thereby improving the stability and reliability of the device.

[0036] In some embodiments, the hanger 4 further includes a bracket 45 for supporting the bottom of the seedlings, and the bracket 45 is connected to the suspension rod 41 and is located below the suspension rod 41. The bracket 45 is installed below the suspension rod 41, and the upper part of the seedlings is fastened to the suspension rod 42 by the suspension rope 43.

The supporting plate 452 is connected to the top of the connecting frame 451, and the supporting plate 452 is perpendicular to the connecting frame 451. In actual use, the supporting plate 452 can be disassembled from the connecting frame 451, or the supporting plate 452 can be rotated around the connecting frame 451 to facilitate the loading and unloading of seedlings.

[0038] In a specific embodiment, Figure 3As shown, a plug hole 4511 is provided at the bottom of the connector, and a plug post 4521 is provided at one end face of the support plate 452. The plug post 4521 is plugged into the plug hole 4511 and fixed by a pin. The plug post 4521 is plugged into the plug hole 4511 to achieve a detachable connection between the support plate 452 and the connecting frame 451. When unloading the seedlings, the pin can be removed and the plug post 4521 can be taken out from the plug hole 4511, thereby facilitating the unloading of the seedlings.

[0039] In some other embodiments, the support plate 452 and the connecting frame 451 may be connected by other means such as bolt connection, snap connection, etc., as long as a detachable connection between the support plate 452 and the connecting frame 451 can be achieved.

[0040] In another specific embodiment, Figure 4 As shown, the bracket 45 further includes a telescopic rod 453, the support plate 452 is hinged to the connecting frame 451, and the telescopic rod 453 is respectively hinged to one end of the support plate 452 away from the connecting frame 451 and the top of the connecting frame 451. The support plate 452 is hinged to the connecting frame 451, and the telescopic rod 453 is respectively hinged to the support plate 452 and the connecting frame 451. The change of the angle between the support plate 452 and the connecting frame 451 is achieved by the extension and contraction of the telescopic rod 453. When loading seedlings, the telescopic rod 453 is extended to rotate the support plate 452 around the connecting frame 451 until it is lowered to the ground, which is convenient for loading seedlings; after loading the seedlings, the lifting and contracting rod is shortened to rotate the support plate 452 around the connecting frame 451 and rise; when unloading the seedlings, the telescopic rod 453 is extended to rotate the support plate 452 around the connecting frame 451 until it is lowered to the ground, which is convenient for unloading the seedlings. The bracket 45 of this embodiment facilitates the loading and unloading of seedlings and improves the convenience of the device.

[0041] In some embodiments, the support plate 452 is provided with water holes 4522. By providing the water holes 4522 on the support plate 452, it is prevented that too much rainwater accumulates on the support plate 452 and damages the root soil of the seedlings, thereby improving the integrity of the seedlings and ensuring the survival rate of the seedlings.

[0042] In some embodiments, two lower tie rods 32 are provided, and the two lower tie rods 32 are respectively connected to the two ends of the connecting rod 33, the connecting rod 33, the carriage 11 and the two lower tie rods 32 form a quadrilateral shape, and the suspension rod 41 is connected to the middle of the connecting rod 33; the transmission mechanism 3 also includes a driving arm 37, and the driving arm 37 is respectively connected to the driving device 2 and the lifting arm 31, and the lifting arm 31 is respectively connected to the two lower tie rods 32. By connecting the two lower tie rods 32 to the two ends of the connecting rod 33, and the suspension rod 41 is connected to the middle of the connecting rod 33, the stability of the lifting of the connecting rod 33 can be improved compared with the structure of a single lower tie rod 32; the driving arm 37 is respectively connected to the two lower tie rods 32, driving the two lower tie rods 32 to rise and fall synchronously, thereby driving the lifting of the connecting rod 33, and improving the stability and reliability of the device.

[0043] In some further embodiments, the transmission mechanism 3 further includes two lifting rods 38, the lifting rods 38 are hinged to the lifting arm 31, and the two lifting rods 38 are respectively hinged to the position of the lower pull rod 32 close to the connecting rod 33. By hingedly connecting the two lifting rods 38 to the position of the lower pull rod 32 close to the connecting rod 33, the distance between the force point of the lifting rod 38 and the connecting rod 33 is closer, the torque can be reduced, and the force on the connecting rod 33 can be reduced while saving more effort, so as to avoid the connecting rod 33 from being damaged due to excessive force, thereby improving the stability and reliability of the device.

[0044] In some embodiments, Figure 5 As shown, the lifting rod 38 includes a middle piece 381, a first connecting piece 382 and a second connecting piece 383. The two ends of the middle piece 381 are respectively connected to the first connecting piece 382 and the second connecting piece 383. The first connecting piece 382 is hinged to the lower rod 32, and the second connecting piece 383 is hinged to the lifting arm 31. The cross-sectional areas of the first connecting piece 382 and the second connecting piece 383 are both smaller than the cross-sectional area of ​​the middle piece 381. The first connecting piece 382 is hinged to the lower rod 32, and the second connecting piece 383 is hinged to the lifting arm 31, so that the two ends of the lifting rod 38 have a rotatable degree of freedom, ensuring that in the process of the lifting arm 31 lifting and driving the lower rod 32 to rise and fall, the lifting arm 31 and the lifting rod 32 can be smoothly rotated and lifted at the same time, ensuring the reliability and stability of the device.

[0045] The working principle of the seedling transporting device is as follows: the driving arm 37 is driven to move by the driving device 2, thereby driving the lifting arm 31 to rise and fall, and the driving arm 37 drives the two lower pull rods 32 to rise and fall synchronously, thereby driving the connecting rod 33 and the hanging rod 41 to rise and fall. When loading seedlings, the hanging rod 41 is lowered to the lowest height, the seedlings are fastened by the hanging rope 43 and hung on the hanging rod 42, and then the hanging rod 41 is raised and transported to the designated position by the transport vehicle 1. When unloading seedlings, the hanging rod 41 is also lowered to the lowest level. The seedlings are convenient to load and unload, and the integrity of the seedlings can be ensured by hanging the seedlings; the support plate 452 can be disassembled from the connecting frame 451, or the support plate 452 can be rotated around the connecting frame 451. When unloading seedlings, the support plate 452 is disassembled from the connecting frame 451, or the support plate 452 is rotated around the connecting frame 451 to be lowered to the ground, so as to facilitate the loading and unloading of seedlings.
