Abstract: A process for weighing a harvested crop stored in a tank of a harvesting machine, a frame supporting the tank is mounted on a wheel set by a lifting device which is operable to move the frame upwardly and downwardly upon control of a hydraulic system. The process controlling the hydraulic system and includes the steps of: determining at least one height position of the frame on the displacement course; measuring a lowering pressure and a raising pressure in the hydraulic system at the position; calculating, from the measured pressures, a balancing pressure for the frame. The process is performed before unloading the stored crop in order to calculate a loaded balancing pressure and after the unloading in order to calculate an empty balancing pressure. The weight of the stored crop is calculated from a pressure variation between the loaded balancing pressure and the empty balancing pressure.

Abstract: A destemmer for use in a fruit harvester includes a frame, a box carried by the frame, and an eccentric drive connected with the box. The box includes an inlet for receiving berries clusters. At least one top link interconnects the box and the frame. The top link include a first end pivotally connected to the frame, and a second end pivotally connected to the box. At least one bottom link interconnects the box and the frame. The bottom link include a first end pivotally connected to the frame, and a second end pivotally connected to the box. The longitudinal axis of each of the top link and the bottom link intersects at a virtual pivot axis, when viewed from a side of the box, which is located upstream from the inlet to the box, relative to a travel direction of the berries and MOG through the box.

Abstract: A cleaning fan system for use in a fruit harvester includes at least one cleaning fan having an inlet and an outlet. The at least one cleaning fan is configured as a mixed flow fan with a rotor having a frustroconical shaped hub and a plurality of blades. The hub includes a smaller diameter inlet end and a larger diameter outlet end. Each blade is attached to the hub and curves forward from the inlet end toward the outlet end, relative to a direction of rotation of the rotor, whereby air is blown during operation both axially and radially. At least one intake duct includes at least one inlet and an outlet. The inlet is positioned in association with an area to be cleaned on the fruit harvester, and the outlet is coupled with an inlet of a corresponding cleaning fan.

Abstract: A harvesting unit including a chassis intended to be moved along rows of plants to be harvested, and a shaker system including a shaker device including: a drum operable to detach a crop from the plants, the drum including a drum shaft mounted for rotation on the chassis about a vertical axis and shaker organs mounted to the drum shaft; a rotational driving mechanism for the drum including a driven body and a first driving device engaged with the driven body to steer its rotation about the vertical axis; an oscillatory driving mechanism for the drum about the vertical axis including comprising an eccentric module and a second driving device engaged with the eccentric module to steer its rotation, the eccentric module being connected to the drum shaft by a mechanical member arranged to transform the eccentric rotation of the eccentric module into an oscillation of the drum shaft.
