Abstract: The invention achieves a mechanical device for pulling seedling plants from the ground in greenhouses and for conveying them by conveyor to a collection receptacle for grading the more mature or better quality plants. Essentially the invention includes an inclined conveyor formed by a pair loop belts, each belt travelling between an idler pulley and a drive wheel, such that the loop belts, being composed of a resilient material such as sponge rubber, are placed in an abutting juxtaposed position to thereby co-operatively form the mechanism which pulls the plant from the ground and as well conveys the plant from the ground toward the collection receptacle.

Abstract: A mobile device for harvesting tree seedlings includes means for subsurface cutting to separate and loosen from the surrounding ground the body of earth adjoining the roots of the tree seedlings. The movement and relative position of the earth separating means enables it to efficiently sever the roots of the tree seedlings from the surrounding ground while allowing only a minimum amount of earth of adhere to the roots of the seedlings as they are removed. A plurality of paired gripper belts remove the loosened seedlings by lifting them upwardly and rearwardly relative to the ground, each pair of gripper belts having male-female intercoupled gripping surfaces which minimize damage to the stems of the seedlings. Disposed below the gripper belts are a plurality of elongated root beater means adapted to move in a transverse oscillatory manner to agitate the roots and remove the earth adhering thereto without damaging the seedlings. A drive linkage mechanism controls the movement of the root beater means and balances the forces resulting therefrom to substantially reduce vibration in the harvester. Finally, an improved sheave structure for the gripper belt drive mechanism enables worn-out bearings to be readily replaced without replacing the entire sheave structure.

Abstract: A device and method for automated, mechanical harvesting of plants having differing heights and stem lengths, wherein a stem portion of the plant must be severed at a uniform, predetermined length from the top of the plant. The inventive method comprises the steps of (i) guiding the stems of the plants into a first severing blade (ii) severing a lower portion of the stems at an excess length to the free the plant from its root and form a precut stem length greater than the predetermined length required for the harvested plant, (iii) guiding the precut stem along a guide track toward a second severing blade which is positioned at a separation distance below the guide track which will cause severance of the stem at the predetermined length, (iv) vertically positioning the precut stem within the guide track such that the top of the plant is at a predetermined elevation with respect to the second severing blade, and (v) severing an additional portion of the stem from the plant by advancing the vertically positioned precut stem to the second severing blade to yield a harvested plant having a uniform, predetermined stem length. Structural components for implementing these steps are disclosed as well as the features of a conveyor belt useful for controlling stem movement, orientation and position displacement through the process.
