The main function of seedling pick-up is to take away theseedlings from seedling trays and place them in to the transplanting hopperfrom where the seedlings are transplanted in to the soil In spite of the factthat the working pace was about the speed of the human hands , it was expectedtoward the start of the investigation to focus numerous endeavors on making theremoving capacity of the seedling pick-up device more exact. Accordingly, thistransplanting operation requires that the pick-up device can dependably get theattachments with no harm to leaves, the stem and the root mass of a vegetableseedling, for that a sensible transplanting design must be made as below.The seedling tray has a movement at an angle ?to the transplanting surface.
The tray movement can be divided in to tray cellto cell horizontal move , row to row length wise feeding . This feed angle hasto be almost perpendicular, which limit the feeding interpretation space and in this manner is more gainful for the structureformat.Picking pins length should be greater than the height of theseedling tray cell, which pick the seedling freely from the tray cellperpendicular to the longitudinal feed movement. For quality-high picking , thepicking pins should go inside the root soil of vegetable seedling along line FEand pick ,lift the seedling in the same path .
In this way we can escape theroot of vegetable seedling from being damageThe opening of pick-up pins should have the width less thanthe width of tray cell and the pick-up pin goes inside the cell which was lessthan height of the tray cell . As thepick-up pins go inside the tray cell , they will close according to the widthof the cell and the minimum width of opening is less than the width of thebottom tray cell . press also, hold the root protuberance solidly at thegreatest entrance profundity.The pick-up pins transfer the seedling from tray along thecurved path FG. From there the seedling is dropped by pick-up pins in to thetransplanting hopper.
From there the seedlings will fall in to the furrow createdby gravity and packed with the packing wheels.
