Abstract: Mechanical post-harvest processing devices for processing plant material by separating a desired portion of plant material from an undesired portion of plant material are shown and described. The mechanical post-harvest processing devices each include: a saddle having a plant material container-proximate region and one or more saddle openings; a plant material container having one or more plant material container openings and an exterior surface proximate the saddle and circumferentially enclosing a post-harvest processing space; and a rotary actuator mechanically connected to the plant material container and configured to rotationally drive the plant material container such that the plant material chamber rotates within the saddle. In some examples, a portion of the one or more plant material container openings and a portion of the one or more saddle openings overlap at one or more positions during rotation of the plant material chamber.

Abstract: Mechanical plant harvesting devices for harvesting crops from plant material including saddles, harvesting containers, and mechanical actuators. In some examples, the saddles define harvesting container-proximate regions over portions of the surface areas and saddle openings positioned within the harvesting container-proximate regions. In some examples, the harvesting containers define exterior surfaces proximate the saddles over at least a portion of the harvesting container-proximate regions of the saddles and harvesting container openings in the exterior surfaces. In some examples, the rotary actuators are mechanically connected to the harvesting containers and are configured to rotationally drive the harvesting containers through ranges of rotation. In some examples, portions of the harvesting container openings and portions of the saddle openings overlap at one or more harvesting positions in the mechanical actuators' ranges of rotation.
