Tree Seedling Planter Public

The goal of this project was to design a trailer mechanism that transplants two year-old evergreen saplings. The mechanism automates the processes of digging holes, planting seedlings, and refilling the holes. To dig the hole, a four bar linkage with a dibble on the end intermittently pierces conical holes into the ground, minimizing soil disturbance. The saplings are held in a hopper and individually separated by an arm on a linkage that reorients and places the saplings into the holes. Finally, two angled wheels on the rear of the trailer refill the holes with surrounding dirt. These systems were designed to operate synchronously using the torque generated by the wheels as they roll across the field. Future research could use this information to actualize the transplanting mechanism.
