Preferably, both ends of the elastic rubber strip are located inside the flange.

The beneficial effect of adopting the above-mentioned technical scheme is that: since the present invention is used for small-batch and accurate transplanting of bare-root seedlings in the laboratory, it does not adopt the common duckbill hanging cup method in traditional field transplanting operations. Instead of a transplanting mechanism, the clamping arm is used to directly clamp and transplant the seedlings. In order to effectively protect the stems and leaves of the seedlings, the invention improves the clamping arm structure. First of all, the present invention adopts the air bag on the upper part of the clamping arm to support and protect the leaf area of the seedlings, which can reduce the possibility of damage to the leaves during the transplanting process. Perform blowing to keep the blades away from the area of the limit rod, so as to avoid crushing damage to the leaves by the limit rod or the air bag. The clamping mechanism is used at the lower part of the clamping arm to clamp and fix the main stem of the seedling. The clamping mechanism The upper and lower positions can be flexibly adjusted according to the size of the seedlings, and the entire seedlings can be transplanted under the condition that the upper part is limited and protected, and the lower part is clamped and fixed. The clips are used in the clamping mechanism to clamp the seedlings. The clips are installed on the slider through the universal joint and the second connecting rod. When the vertical force between them increases instantaneously, buffering can be performed to prevent the clips from damaging the surface of the main stem of the seedlings. As the clamping force between the clamping mechanism and the seedlings increases, the sliding friction between the second connecting rod and the rubber layer will also increase synchronously, thereby applying damping to the sliding of the slider and preventing the slider from reciprocating in the chute shaking. The universal joint can enable the clip to hold and fix the main stem at different angles well. Since the top of the clamping arm is hinged, the upper part of the clip first contacts the seedlings when clamping the seedlings. In order to reduce the probability of clamping failure of the clips, an arc-shaped guide plate is set up to preliminarily check the position of the seedlings and the clips. Position-limiting guide, and then with the closing of the clamping arm, the elastic extension plate clamps the seedlings to realize the horizontal clamping and fixing of the seedlings, and the soft pad is used to protect the seedlings. After the elastic extension plate clamps the seedlings, the seedlings press down the inner end of the retainer, so that the outer end of the retainer is upturned, so that the two retainers on the same elastic extension plate form a "concave structure", and the seedlings are in the "sag structure". The limited fixation is realized in the "depressed structure", which can improve the stability of the lateral clamping of the seedlings without increasing the risk of damage to the seedlings. The flanges on both sides of the airbag body can overlap with the side branches of the seedlings after being inflated, so that during the transplanting process, the overlapping of the flanges and the side branches can be used to cooperate with the clamping mechanism to exert force on the seedlings at multiple points. Thereby further avoiding that the main stem of the seedling is overstressed and damaged. At the same time, the seedlings can be prevented from shaking during the transplanting process through the effective overlapping of the airbags to limit the seedlings, thereby improving the clamping stability of the clamping mechanism for the seedlings.
