[0041] In this embodiment, the supporting shaft 13 is provided with a driven gear 17. The front side cross beam plate 3 is provided with a driving shaft 21 through a bearing shaft. The front end of the driving shaft 21 is provided with a handle 20, and the rear end is provided with a driving pinion 22 which is engaged with the driven gear 17 for transmission. The driven gear 17 provided on the supporting shaft 13, the driving shaft 21 provided on the front side cross beam plate 3, the handle 20 at the front end of the driving shaft 21 and the driving pinion 22 provided at the rear end of the driving shaft 21 together constitute a mechanical transmission system. Through the design of the handle 20 and the driving shaft 21, the operator can manually control the seedling process of the seedling bed, which is high in flexibility and strong in adaptability.

Since the limiting rod 62 is inserted into the sleeve 63 and is slidably connected thereto, the movement range of the top plate 26 is limited by the sleeve 63. When the top plate 26 moves to the limit position, the limiting rod 62 will contact the end of the sleeve 63, thereby preventing the top plate 26 from continuing to move, achieving the limiting function. The combination of the upper support plate 61, the lower support plate 64, the sleeve 63 and the limiting rod 62 forms a stable support and limiting structure, ensuring the stable movement and accurate limiting of the top plate 26, effectively preventing the top plate 26 from shaking during movement, making the movement of the top plate 26 more stable and smooth.

[0046] In this embodiment, the bed body 1 is provided with a guard plate 4 around the upper edge. The bottom of the guard plate 4 is hingedly connected to the bed body 1 through a hinge 41, and adjacent two groups of guard plates 4 are detachably connected through a lock buckle 42. The guard plate 4 is installed around the upper edge of the bed body 1, forming a surrounding protection structure. The guard plate 4 can shield and protect the seedlings that are pushed out of the seedling bed 7 during seedling lifting, preventing them from falling off the edge of the bed body 1 and being damaged. The hinge 41 and the lock buckle 42 can fold the guard plate 4 when not needed, reducing the occupied space and facilitating quick connection.

[0047] The working principle of the cutting seedling bed is as follows:

[0048] In actual use, the cutting seedling of Akebia trifoliate is cultivated in the seedling groove 7, when it is needed to be lifted, first, the guard plate 4 is turned up and surrounded on the bed body 1, and is connected and fixed through the lock catch 42. Then the handle 20 is rotated, the driving shaft 21 is driven through the handle 20, the driving small gear 22 at the rear end of the driving shaft 21 is engaged and driven with the driven large gear 17 on the supporting rotating shaft 13, and the supporting rotating shaft 13 is rotated. The rotation of the supporting rotating shaft 13 further drives the cam 14 on it to rotate. When the cam 14 rotates, the contour change pushes the bottom of the driven branch 15 equipped with the roller to move up, the driven branch 15 drives the center fixed plate 16 and the top plate 26 and the hollow top rod 5 on it to rise. The lifting top disc 10 at the top of the hollow top rod 5 lifts the supporting plate 8 in the seedling groove 7, and then lifts the seedling, so that the seedling is separated from the seedling groove 7. At this time, the pawl 19 is manually adjusted to be clamped into the ratchet wheel 18, the ratchet wheel 18 is clamped and fixed through the pawl 19, and then the supporting rotating shaft 13 is locked to prevent it from rotating by itself. Then the Akebia trifoliate seedling after lifting is taken out one by one.
