The shaker assembly comprises a support provided with at least one cavity and at least one shaker rod configured to be clamped into said cavity. The cavity comprises an entry portion and a clamping portion, oriented along different angles and partly overlapping each other. The entry portion is shaped and dimensioned to enable sliding the rod into and out of said entry portion, while the clamping portion is shaped and dimensioned to clamp the rod by a radial clamping force. The cavity further comprises at least one bottleneck area that is narrower than the shaker rod, enabling to move the rod from the entry portion to the clamping portion or vice versa by tilting the rod between said different angles, thereby forcing the rod to pass through said bottleneck area or areas.

A detection device for metal stakes in a wire-trained plant-crop hedge having at least one detector configured to generate a detection signal when it passes next to a metal stake of the hedge wherein the metal stake detector has a first and a second metal detector arranged for generating respectively a first and a second measurement signal when they pass next to one of the metal stakes of the hedge. The first and second metal detectors are mechanically secured to each other in movement and arranged for being spaced vertically relative to each other. The detection device has an electronic management unit for the detection signals, configured for, upon detection of a temporal offset between the maximum variation levels of the first and second measurement signals, generating a signal indicating an inclined state of the metal stake.

A trellis and DOV grape growing system utilized for grape vines, featuring an overhead training wire system that allows for the positioning of canes in a multi-quadrant arrangement. The canes are supported by posts positioned along adjacent rows of vines. The system includes a network of training wires which allow the canes to be directed in multi-axial directions from each vine. The trellis system allows the grapes to desiccate under solar warmth while on the vine, thus forming raisins. The DOV grapes may then be efficiently harvested by a vehicle having a canopy-shaking apparatus passing under the trellis canopy.

A field harvesting device for small fruits having a harvesting header, a hitching pole and framework on wheels so as to be pulled by a moving motorized machine and the harvesting header is a single assembly comprised of a frame, conveyor, dividing cones, and a plurality of assemblies formed at first by worm screws, from each of which individual worm screw extends a rotating separator from which extends a shaft extending into a sprocket wheel. Two of the assemblies working as a pair of axially parallel aligned assemblies such that when one rotating separator, forming part of the pair, rotates clockwise and faces the other rotating separator forming part of the same pair rotates counterclockwise. The counter rotating separator having paddles which are configured for stripping fruits off of fruit plants; the stripped fruits are projected upwards by the action of the paddles rotating in an upward direction; the fruits fall onto U shaped cups located on the underneath supports, and roll off onto a primary conveyor. The primary conveyor conveys the fruits to an elevator conveyor which directs the fruits into a container. The assemblies are linked together at the back of the harvesting header by way of a roller chain connected to the sprocket wheels which are rotationally connected to pillow bearings mounted to the harvesting header frame and covered by a back cover. The assemblies are hold at the front end of the device by supports brackets mounted on a header frame member, which are rotationally connected by way of bearings that allow rotational movements of the assemblies.

An autonomous harvesting machine for orchard operating environments is described. The autonomous harvesting machine uses machine vision techniques to identify and triangulate features in the operating environment using a stream of monocular images. For instance, the harvesting machine identifies and localizes a shake point of a tree by projecting virtual rays from the pose of the identification system to the identified emergence point feature. To harvest the fruit of trees in the orchard, the harvesting machine shakes the tree at the identified shake point. Additionally, the harvesting machine autonomously navigates through the orchard using a combination high resolution spatial information based on localized features and low resolution spatial information from accessed satellite images.

A method for operating a permanently excited synchronous motor of a hand-held working device includes the steps of: sensorlessly determining a position variable representative of a position of a rotor of the synchronous motor at a standstill; determining a direction variable for a continuous rotation of the rotor from standstill in a direction on the basis of the determined position variable such that an absolute value of an attainable torque that can be generated by the synchronous motor during its sensorless actuation for the rotation in the direction is greater than an absolute value of a breakaway torque limit of the working device; and sensorlessly actuating the synchronous motor on the basis of the determined direction variable for the rotation in the direction.

The double-swing-rod mechanism includes a supporting main body used for rigidly supporting a fruit picking machine, a rotating shaft component connected to the supporting main body, two conical gears that axially rotate around the rotating shaft component, two swing rods movably connected to the two conical gears respectively to achieve a swing effect, and a drive gear movably connected to the supporting main body.
