In addition, an insertion end 24 is also provided on the support frame 23, and a positioning hole 25 is provided on the insertion end 24; at the same time, a sliding mechanism 26 is provided at the bottom of the support frame 23, which can effectively adjust the position of the second hook 27 so that the second hook 27 is compatible with the first hook 20. The second hook 27 can be pulled by the sliding mechanism 26, so that the first movable plate 11 and the second movable plate 12 can be opened or closed at the same time.

[0055] After the seedling picking mechanism 3 rotates to the right position, the second hook 27 is opposite to the first hook 20, and the second hook 27 can pull the first hook 20 through the sliding mechanism 26, and the lower rack 18 and the second movable plate 12 can be moved together by pulling the first hook 20, and then the lower rack 18 drives the rotating gear 16 to rotate, thereby driving the upper rack 17 and the first movable plate 11 to move in the opposite direction. When the first movable plate 11 and the second movable plate 12 are closed, the rice seedling skin can be placed in the seedling support frame 5, and when the first movable plate 11 and the second movable plate 12 are opened, the rice seedling skin will fall on the seedling receiving plate 7.

[0056] The sliding mechanism 26 includes a sliding motor 38 and a sliding screw 39 . The sliding motor 38 is connected to the sliding screw 39 , and the second hook 27 is disposed on the sliding screw 39 .

[0062] The lifting mechanism 1 further includes a slide 56 , which is disposed between the lifting platform 36 and the frame 2 to facilitate the lifting and lowering movement of the lifting platform 36 relative to the frame 2 .

[0063] The seedling taking device of the unmanned rice transplanter with automatic continuous seedling supply is in the initial state when the rice transplanter is working (such as Figure 1 As shown), the seedling support frame 5 is filled with rice seedling skins, and the seedling taking mechanism 3 is located in the middle position of the uppermost part.

[0064] When the upper travel switch on the seedling receiving plate 7 detects that there is no seedling, the seedling taking mechanism 3 rotates rightward, and the insertion end 24 is inserted into the opening 32 of the seedling supporting frame 5. At this time, the first hook 20 is opposite to the second hook 27, and the positioning hole 25 on the insertion end 24 is opposite to the pin 33 (such as Fig. 9 shown).

When the first stroke switch 40 is fully opened, the lifting mechanism drives the seedling receiving plate 7 to be lifted and leveled to take the seedlings.

[0071] During the seedling removal process, if the second stroke switch 42 on the seedling box 41 is not turned on, after the seedling receiving plate 7 is loaded with seedlings, the lifting mechanism drives the seedling receiving plate 7 to flip downward, and the seedlings automatically slide into the seedling box 41; during the seedling removal process, if any second stroke switch 42 on the seedling box 41 is turned on, the seedling receiving plate 7 flips downward, and the seedlings automatically slide into the seedling box 41; when the first stroke switches 40 are all turned on again, the seedlings are loaded first according to the seedling loading sequence that was not completed last time.
