High-speed transplanter for seedlings attached to tape

摘要

An automated transplanter has been designed for seedlings previously loaded and correctly spaced on a low tensile-strength, biodegradable tape wound on a spool. The transplanter design allowed for rapid planting of the tape with the attached seedlings while minimizing the tension placed on the tape. The design linked the unspooling of the tape directly to the ground speed of the tractor and provides for an anti-backlash mechanism to prevent the spool from free-wheeling when the tractor speed slowed quickly. Using this design, synthetic seedlings attached to a low tensile-strength tape were successfully planted at speeds up to 7.5 mph.
