An apparatus for selectively harvesting a plant material (such as tea plants) having a stem. The apparatus has a first plant material engaging element rotatable about a first axis, and a second plant material engaging element rotatable about a second axis in the opposite direction to, and synchronized at a fixed ratio with, rotation of the first engaging element. The first and second engaging elements each have a moveable engagement surface to entrap a first respective upper portion of a plant stem therebetween. With continued rotation, the first and second engaging elements pull the entrapped first respective upper portion of the plant over a time period so as cause increasing tension in a second respective lower portion of the plant stem. The second engaging element has a plant material breaking surface which is moveable along an arc so as to contact the second respective lower portion of the plant stem.

This automated driving system for a work vehicle is provided with: an inertia measuring device that obtains tilt information of a work vehicle; and an automated driving control unit that causes the work vehicle to automatically travel along a target path. The work vehicle is provided with a work device that carries out a predetermined work with respect to a part to be worked on that is positioned away from the ground. The automated driving control unit calculates an offset amount on the basis of height information of a work center of the work device and the tilt information, and controls the location of the work vehicle with respect to the target path on the basis of the offset amount.

Provided is an integrated harvesting device for picking and sorting famous tea. The device includes a frame, a control module, and a traveling module, a picking module, a conveying module, a sorting module, a collecting module and a visual detection module which are electrically connected to the control module. The traveling module is installed at a lower end of the frame, the picking module is installed on the frame and arranged adjacent to a front end and the lower end of the frame. The picking module can pick tea leaves with assistance of the visual detection module. The conveying module and the sorting module are both installed on the frame, the conveying module is configured to convey tea leaves picked by the picking module to the sorting module.
