Row type seed-leaf-direction-adjustable seedling feeding device

Abstract

The invention relates to a row type seed-leaf-direction-adjustable seedling feeding device. The row type seed-leaf-direction-adjustable seedling feeding device is capable of automatically performing positioning, root breakage, clamping and seed leaf direction adjustment operations for grafted seedlings in a whole row in a seedling tray, automatically adjusting the unordered seed leaf directions to the direction suitable for grafting and providing the grafted seedlings for rootstock woods and scion woods so that subsequent full-automatic grafting efficiency is improved. The technical scheme includes that the row type seed-leaf-direction-adjustable seedling feeding device is characterized by comprising a positioning mechanism, a clamping mechanism and a seedling cutting mechanism, wherein the positioning mechanism comprises a group of gripping connecting rods, a restraining stop plate and at least one arc-shaped stop plate mounted on the clamping mechanism; the clamping mechanism comprises a group of mechanical grippers and air cylinders; and the seedling cutting mechanism comprises a cutter which is horizontally arranged and driven by an external actuator.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable grafting, in particular to a cotyledon direction-adjustable seedling lifting device of a fruit and vegetable grafting machine. Background technique [0002] Grafting is a method of artificial vegetative propagation of plants, that is, grafting branches or buds of one plant to the stem or root of another plant, so that the two parts grow into a complete plant. In these two parts, the seedlings that bloom and bear fruit are usually called earwood, and the seedlings that are stuck in the soil to absorb water and nutrients are called rootstocks. The seedlings of vegetables and fruits are very slender. The diameter of the earwood is generally only about 1 mm, and the diameter of the rootstock is only about 3-4 mm. Moreover, the suitable period for vegetable grafting is relatively short, generally only a few days, so the operator needs to have high skills Graft two seedlings together accura...

AI Technical Summary

Problems solved by technology

[0004] In a conventional fruit and vegetable grafting machine, the manipulator claws of the seedling actuator will be affected by the randomness of seedling growth when performing the seedling picking operation, that is, the seedlings are not vertical enough, and the manipulator grips in the gripping process. Problems such as accuracy and seedling injury have yet to be resolved
