Seedling picking mechanism for plug-seedling transplanter

Abstract

The invention discloses a seedling picking mechanism for a plug-seedling transplanter and relates to the field of dry land transplantation machinery. The seedling picking mechanism comprises a planet carrier (1), a central wheel (2), a planet wheel A (3), a planet wheel B (4), a seedling picking claw (6), a connecting rod A (7), a roller (8), a groove-shaped cam (9) and a connecting rod B (10). The seedling picking mechanism has the advantages of high motion precision, easy control, simple whole structure, reliable work, convenient use, low manufacturing cost, high reliability and capacity of meeting complex requirement on field transplantation environment.

Description

technical field [0001] The invention relates to the field of dry land transplanting machinery, in particular to a seedling picking mechanism capable of driving seedling picking claws to pick up seedlings from hole holes in a tray according to a specific path, and bring the seedlings to the seedling throwing position to release the seedlings. Background technique [0002] The seedling picking mechanism of the plug seedling transplanting machine is an important part of the plug seedling automatic transplanting machine. Its main function is to drive the end effector of the seedling picking mechanism to take out the seedlings from the hole of the plug tray according to a certain path, and entrain the seedlings Put the seedlings at the seedling opening of the seedling planter of the transplanting machine. At present, most of the transplanting machines used in field operations are semi-automatic machines, and the seedlings still need to be supplied manually, that is, the seedlings...

AI Technical Summary

Problems solved by technology

A kind of automatic seedling-taking mechanism that is used for pot seedling transplanting such as my country's patent CN200920065731.9 announces, has adopted crank slider mechanism, clamping seedling mechanism, cam mechanism, parallelogram mechanism, realizes the automatic opening of seedling-taking claw and from carrying seedling The pot seedlings are clamped and placed in the table or hole tray, but the patent does not point out the movement track of the seedling claws; in 2000, Xu Liming of China Agricultural University designed an automatic seedling picking mechanism for corn transplanters. The connecting rod mechanism drives the seedling claws to be inserted into the seedling pot to realize the seedling picking action, and it is pointed out that the movement track of the terminal point of the seedling finger depends on the length of the four connecting rods and the positions of the connecting points in the four-bar linkage mechanism
