ABSTRACT:
The transplant head of the transplanter has an upper plate with four pinholes spaced at the corners of a square of a determined width. A lower plate is adjustably spaced beneath the upper plate and has four pinholes located at the corners of a square of a lesser width than the upper plate pinhole spacing. Four transplant pins extend between the upper and lower holes such that when the upper plate is brought closer to the lower plate by a pneumatically activated mechanical linkage, the pins converge within a seedling plug. Additional pins and pinholes provide for transplanting of an array of seedlings. A pneumatic actuator is connected to the lower plate and is adapted to elevate the transplant head with engaged plug. A carriage is driven by a pneumatic actuator to position a growth pot beneath the engaged plug. A computer controller causes the plug to be lowered into the soil of the growth pot after which the mechanical linkage may be activated to space the plates to disengage the pins from the plug. A table supports the seedling tray beneath the transplant head and is positionable at selected positions such that an array of pins in the transplant head may incremently transplant the seedlings of a tray into a plurality of flats.
