Design and development of an automatic vegetable transplanter using a novel rotating finger device with push-type mechanism for plug seedlings

Design of seedling picking mechanism for automatic transplanting machine for nodular vegetables

“…Seedling transplanting can improve soil utilization and seedling emergence rate, and the survival rate of transplanting is high [2]. At present, the development of automatic transplanting machine in China is slow compared with that of foreign countries [3], with the increase of labor cost, the demand of using machinery, automation and other technologies for vegetable planting is more urgent [4][5].…”

Design and evaluation of a power tiller vegetable seedling transplanter with dibbler and furrow type

“… SL No. Transplanter Type Power Sources Mechanized types Design Parameters Results References 1 Power tiller operated vegetable transplanter Power tiller Semi-automatic Inclined press wheels attachment for transplanting on flat bed, and the mould board with truncated conical ridge shaper attachment Effective field capacity was found to be 0.057, 0.058, 0.073, 0.046 and 0.074 ha h −1 for transplanting cabbage, chilli, tomato, knolkhol and brinjal, respectively [ 12 ] 2 Tractor mounted vegetable transplanter Tractor Semi- automatic Conical distributor cup into the fall tube and transferred to the furrow formed by the furrower Field experiment was conducted at the three levels of forward speed, and two levels of cultivation depth at 5 and 10 cm [ 13 ] 3 Walk-behind hand tractor two-row vegetable transplanter Power tiller Automatic Horizontal chain conveyor to a hopper-type planting device Planting rate of the transplanter was 31 plants min −1 and the field capacity was 0.045 ha h −1 for transplanting tomato and chilli pepper [ 14 ] 4 Tractor mounted automatic vegetable transplanter Tractor Automatic Rotating finger device with a push-type mechanism for plug seedlings Field transplanting efficiency and effective field capacity was 76.12% and 0.093 ha h −1 , respectively [ 15 ] 5 Power tiller operated paddy transplanter Power tiller Semi-automatic Modification of the planting claw Increase in spacing resulted in more tillers and more panicle per plant, increase in yield with an increase in spacing [ 16 ] ...…”

Design, development and application of a compact robotic transplanter with automatic seedling picking mechanism for plug-type seedlings

“…Looking at the shortcomings of SVTs viz. labour demanding, lower efficiency, lower accuracy, etc., focus has been changed towards the growth of AVTs 28 . These AVTs uses electro-mechanical system for achieving its desired function.…”
