[0029] Specifically, the first clamping mechanism 204 includes a first servo 2041 and two first clamping claws 2042, both of which are arranged on the slide 203. The two first clamping claws 2042 are rotatably connected to the slide 203. One end of the two first clamping claws 2042 constitutes the seedling clamping end, and the other ends of the two first clamping claws 2042 are respectively connected to the first gears 2043. The two first gears 2043 are meshed with each other, and one of the first gears 2043 is coaxially connected to the first servo 2041.

[0030] Specifically, the second driving mechanism 202 includes a driving motor 2021 arranged on the main frame 1, a synchronous belt 2022, a first synchronous wheel 2023 located at the top of the vertical arm 201, and a second synchronous wheel 2024 rotatably arranged at the bottom of the vertical arm 201, the first synchronous wheel 2023 is transmission-connected to the output end of the driving motor 2021, the first synchronous wheel 2023 and the second synchronous wheel 2024 are connected by the synchronous belt 2022; the slide 203 is connected to the synchronous belt 2022.

The top surface of the storage bin 501 is designed to be open, and a second side opening is disposed on the side of the storage bin 501 close to the guide sleeve 402. The push rod 502 pushes the grafting clamp 6 in the storage bin 501 into the first side opening 4021 under the control of the fourth driving mechanism 503, and the grafting clamp 6 fixes the grafting end of the spike seedling and the grafting end of the rootstock seedling together. Figure 7 As shown, in this embodiment, the fourth driving mechanism 503 is also a gear rack 4013 mechanism. The push rod 502 is slidably connected to the placement bin 501. The push rod 502 is provided with a latch tooth, which meshes with the gear below. The gear is then driven by a motor or a servo to control the displacement of the push rod 502.

[0035] Specifically, the first driving mechanism 401 includes a base 4011 arranged on the main frame 1, a third servo 4012 arranged on the base 4011, a rack 4013 horizontally slidably arranged on the base 4011, and a driving gear 4014 adapted to the rack 4013, the driving gear 4014 is transmission-connected to the output end of the third servo 4012, and meshes with the rack 4013; one end of the rack 4013 is connected to the guide sleeve 402.

[0036] In some implementations of this embodiment, both ends of the guide sleeve 402 are inverted cone-shaped structures to facilitate the grafted ends of the spike seedlings and the grafted ends of the rootstock seedlings to enter the guide sleeve 402 .

[0037] Working principle:

[0038] When not grafted, the two first clamping claws 2042 and the two second clamping claws 3032 are both in an open state.

[0039] During grafting, the fringe seedling to be grafted is placed between the two first clamping claws 2042, and the grafting end of the fringe seedling is directed toward the top of the guide sleeve 402. Then the first steering gear 2041 operates to close the two first clamping claws 2042 to clamp the fringe seedling to be grafted. Similarly, the rootstock seedling to be grafted is placed between the two second clamping claws 3032, and the grafting end of the rootstock seedling is directed toward the bottom of the guide sleeve 402. Then the second steering gear 3031 operates to close the two second clamping claws 3032 to clamp the rootstock seedling to be grafted.

[0040] Before docking, the guide sleeve 402 moves horizontally to a suitable position under the control of the first driving mechanism 401, so that the grafted end of the fringe seedling and the grafted end of the stock seedling can be respectively extended into the guide sleeve 402. Then the second driving mechanism 202 works to move the slide 203 downward, and the downward movement of the slide 203 drives the first clamping mechanism 204 to move downward. When the grafted end of the fringe seedling extends into the guide sleeve 402, the second driving mechanism 202 stops working. The third driving mechanism 301 works to move the support plate upward, and the upward movement of the support plate drives the second clamping mechanism 303 to move upward. When the grafted end of the stock seedling extends into the guide sleeve 402 and is aligned and abutted with the grafted end of the fringe seedling, the third driving mechanism 301 stops working.

[0041] When the grafting end of the fringe seedling is aligned with the grafting end of the rootstock seedling, this part is located in the guide sleeve 402. Then the fourth driving mechanism 503 works to move the push rod 502 toward the guide sleeve 402, thereby pushing the grafting clamp 6 out of the placement bin 501. In the process of leaving the placement bin 501, the grafting clamp 6 is squeezed by the second side opening, causing its clamping part to open. When the grafting clamp 6 moves to the grafting end, its clamping part wraps the grafting end inside. At this time, the grafting clamp 6 is closed due to elasticity without the squeezing of the second side opening, thereby clamping the pepper seedling and the rootstock, and completing the grafting.

It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
