A device and method for automatically picking and placing seedlings with movable fingers

Abstract

The invention relates to an automatic tray seedling picking and releasing device with movable fingers and an automatic tray seedling picking and releasing method. The automatic tray seedling picking and releasing device with the movable fingers comprises a mechanical cantilever palm, a supporting rod, a finger distance regulating plate, tray seedling clamping finger bodies, finger tips, functional stoppers, finger stretch and retraction driving units and finger tip motion driving units, wherein the tray seedling clamping finger bodies move vertically under the driving of the finger stretch and retraction driving units and are vertically inserted into tray seedlings; the finger tips can rotate to point at the horizontal direction under the driving of the finger tip motion driving units so as to pick the tray seedling and also can rotate to vertical positions to release the tray seedlings. The finger tip motion driving units are arranged to control the finger tips to rotate to point at the horizontal direction on the basis that the tray seedling clamping finger bodies are vertically inserted into the tray seedlings, and the tray seedlings are firmly clamped in both vertical and horizontal directions, so that the tray seedlings are unlikely to slip off, the defect that the tray seedlings and pot bodies thereof are damaged by too large clamping forces during only transverse tightening of the tray seedling clamping finger bodies and the other defects are overcome; the device and the method are applicable to automatic transplantation of the tray seedlings with different specifications.

Description

technical field [0001] The invention relates to an automatic transplanting technology for plug-in seedlings, in particular to an automatic transplanting technology for plug-in seedlings with gripping fingers and rotatable fingertips. Background technique [0002] Industrial seedling cultivation of vegetables, flowers and other crops is the pioneer of modern agriculture and factory agriculture, and has become the industry leader of modern vegetables and flowers. The industrialization of seedlings has great potential for development, and automated seedling raising and transplanting equipment is the key technical equipment for the seedling industry. Plug seedling transplanting technology started earlier in developed countries. Holland has widely used plug seedling automatic transplanting machines (such as Visser Group’s Pic-O-Mat PC series automatic transfer machines, etc.) in greenhouse flower production. Seedlings are automatically transplanted from high-density plug trays ...

AI Technical Summary

Problems solved by technology

The structure of this invention is complicated, and the rubber finger air bag is required to deflate and inflate, and the spring is tightened to stretch and tighten, and the gripping force is not easy to control. The plate seedlings are easy to fall, the success rate of seedling picking is low, and it is easy to damage the seedlings
