[0087] 3. The gripper of the utility model pushes the plastic part, the spring plate opening angle, the bottom is explored from both sides of the plug tray, the plastic part spring plate is pulled after the bottom, and the material in the plug tray is taken out; the waste material is removed, and the good seedling is placed in the hole of the plug tray through the linear module moving forward, backward, left and right; the gripper structure of the utility model is applied to the seedling transplanting and replanting, the accuracy of clamping is improved, and the working efficiency of the machine is improved.

[0088] 4. The seedling pressing assembly of the utility model, the guide device is pressed in the groove on both sides of the plug tray, and the stability of the plug tray in the material grabbing process is fully guaranteed; the displacement problem of the plug tray is solved, the plug tray is displaced by the repeated grabbing and replanting of the gripper structure, especially the up and down displacement of the plug tray, the position is more stable after the seedling pressing assembly, and the operation is more accurate.

[0089] The above is only a specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the technical field can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
