Adopt the beneficial effect that above-mentioned technical scheme brought to lie in: because the invention is used for carrying out the bare-root seedling transplanting operation in small batch and accurately in a laboratory, a duckbilled suspended cup type transplanting mechanism which is common in the traditional field transplanting operation is not adopted, and the seedling is directly clamped and transplanted by the clamping arm. In order to effectively protect the stems and leaves of seedlings, the structure of the clamping arm is improved. Firstly, the upper part of the clamping arm is provided with the air bag for supporting and protecting the blade area of the seedling, the possibility of damage of the blade can be reduced in the transplanting process, the air jet holes are used for blowing the blade through air flow in the seedling clamping process so as to enable the blade to be far away from the vicinity of the limiting rod area, the blade is prevented from being extruded and damaged by the limiting rod or the air bag, the main stem of the seedling is clamped and fixed by the clamping mechanism at the lower part of the clamping arm, the vertical position of the clamping mechanism can be flexibly adjusted according to the size of the seedling, and the whole seedling is transplanted under the states of upper limiting protection and lower clamping fixation. Use the clamping piece to carry out the centre gripping to the seedling among the fixture, the clamping piece passes through universal joint and second connecting rod and installs on the slider, and the slider can realize the slip of limited distance in the spout to can cushion when the vertical effort between clamping piece and seedling increases in the twinkling of an eye, avoid the clamping piece to harm the surface of seedling stem. Along with the clamping-force increase between fixture and the seedling, the sliding friction between second connecting rod and the rubber layer also can increase in step to exert the damping to the slip of slider, avoid the slider to appear reciprocating rocking in the spout. The universal joint can lead the clamping piece to well clamp and fix the main stems at different angles. Because the top of centre gripping arm is articulated, the upper portion of clamping piece first contacts the seedling when the centre gripping seedling of event clamping piece, in order to reduce the probability of clamping piece centre gripping failure, has set up the arc deflector, carries out preliminary spacing direction to the position of seedling and clamping piece, then along with the closure of centre gripping arm, elasticity extension plate centre gripping seedling, and the realization is fixed to the horizontal centre gripping of seedling, and the cushion is used for protecting the seedling. After elasticity extension plate centre gripping seedling, the seedling pushes down the medial extremity of separation blade to make the outside end upwarp of separation blade, thereby make two separation blades on the same elasticity extension plate form one "sunk structure", the seedling realizes spacing fixedly in "sunk structure", sunk structure "can improve the stability to the horizontal centre gripping of seedling under the prerequisite that does not increase the damage seedling risk. The flanges at the two sides of the air bag body can be in lap joint with the lateral branches of the seedlings after being inflated, so that the flanges and the lateral branches can be matched with the clamping mechanism to apply force to the seedlings at multiple points in the transplanting process, and the main stems of the seedlings are further prevented from being damaged due to overlarge stress. Meanwhile, the air bags are used for limiting the effective lap joint of the seedlings, so that the seedlings can be prevented from shaking in the transplanting process, and the clamping stability of the clamping mechanism to the seedlings is improved.
