A clamping and pressing device for terminal buds obliquely inserted into grafted rootstocks

Abstract

The invention discloses a device for clamping and pressing seedlings used for oblique insertion of terminal buds into grafted rootstocks, which comprises a support foot, a base, a clamping mechanism and a seedling pressing mechanism. The clamping mechanism includes a finger cylinder and a clamping piece, the finger cylinder is fixed at one end of the base, and the clamping piece is installed on the finger cylinder; the seedling pressing mechanism includes a base, a seedling pressing sheet, a connecting frame, a pushing frame and The seedling pressing cylinder, the base can be slidably installed on the base, the cylinder body of the seedling pressing cylinder is fixed on the other end of the base, and the base is located between the finger cylinder and the seedling pressing cylinder; one end of the seedling pressing sheet It is connected with one end of the connecting frame, the other end of the connecting frame is hinged to the base, one end of the pushing frame is installed on the piston rod of the seedling pressing cylinder, and the other end of the pushing frame is connected with the middle part of the connecting frame. The invention has the advantages of simple structure, convenient operation, improved working efficiency and guaranteed survival rate of grafting.

Description

technical field [0001] The invention relates to a terminal bud oblique insertion grafting machine, in particular to a clamping and pressing device for terminal bud oblique insertion grafting stock. Background technique [0002] Grafting is often required in modern agricultural planting. With the development of grafting technology, the mechanization level of grafting technology has been greatly improved, and the survival rate of grafting has also made great progress. However, in mechanical grafting, the traditional grafting rootstock clamping and pressing device fixes the integral clamping piece on the pneumatic gripper, and the rootstock seedlings are clamped by starting the opening and closing of the gripper, and the seedling pressing part is controlled by two air cylinders. Drive the linear reciprocating motion of the seedling pressing sheet and the rotation of lifting and pressing respectively. Therefore, the current device for grafting has a complex structure, inconven...

AI Technical Summary

Problems solved by technology

Therefore, the current device for grafting has complex structure, inconvenient operation, and low work efficiency, resulting in low efficiency of rootstock punching and clamping operations in the whole grafting process.

Due to the use of the current grafting device for grafting, the operation time is too long, which causes the grafted rootstock to be easily oxidized, resulting in low survival rate and economic loss.
