A shaker device including at least one motorized member that is intended to transmit by contact a shaking force to objects to be shaken. The member includes a plurality of structural inserts that are covered by a wear jacket. Each of the structural inserts has respective left lobes and right lobes. The inserts are distributed in the jacket so as to form a respective discrete stack of left lobes and right lobes.

A Manoeuvring rod comprising a first elongated portion tubular-shaped and provided with a handle portion configured to be grasped by a user, and a second elongated portion engaged to the working tool). The elongated portions are mutually telescopically engaged in such a way to be able to freely slide one with respect to the other. A blocking/unblocking device is then provided arranged to move from a blocking configuration, in which impedes the above disclosed free sliding, to an unblocking configuration, in which, instead, allows the above disclosed free sliding. The above mentioned movement of the blocking/unblocking device from the blocking configuration to the unblocking configuration, or vice versa, is directly actuated by the user by acting on a control member positioned at the handle portion.

A graphical user interface is disclosed for controlling a harvesting system, the harvesting system driving each of two shaking actuator frequencies individually, the user interface setting or displaying the frequencies of the two actuators as a single point on a displaya Frequency-Frequency User Interface (FFUI). The FFUI abstracts the tuning process of shaking with independent frequency control, allowing a user to choose the parameters for shaking the tree, e.g., frequencies, duration at a given frequency, etc., all while observing the effects of the shake taking place on the tree. The FFUI employs user gestures to map the shaker eccentric speeds and directions to the x and y coordinates of a graph, with the length of time a user gesture remains at any given coordinate pair determining the time that the first and second eccentric frequencies are driven according to the values of the given coordinate pair.

Systems, device, and methods for harvesting fruits or nuts are disclosed. Some fruits or nuts grow on trees, such as almonds. A two-piece harvester is disclosed that mitigates damage to fruits or nuts deposited on the ground after harvesting from the tree. The two-piece harvester may include a shaker configured to shake a tree and cause the fruits or nuts to fall and a receiver configured to collect the fallen fruits or nuts and deposit the fruits or nuts on the ground or in bins. The shaker and the receiver may include cabs that is configured to be in a plurality of different positions. The shaker may also include a wheel that is extendible between a retract position and an extended position. The receiver may also include chute that is configured to deposit the fruits or nuts in different locations based on the direction of travel of the receiver.

A harvester using shaking to dislodge product from trees in which the shaking in each of at least two inertial force generators is controlled independently of the others. Embodiments provide the flexibility to adapt a harvesting procedure to different product and to adapt the harvesting procedure to different individuals within a particular type of plant, and in real-time.

A berry harvester provides flexible cushioned elements and surfaces to limit bruising of the fruit harvested. A chassis defines a picking tunnel that passes over rows of plants. A picking system removes fruit from the plants as the harvester moves along the rows. A catching system configured to receive fruit removed from the plants. The catching system includes resilient catch assemblies on each side of the picking tunnel, each of the catch assemblies at least partially overlapping adjacent catch assemblies. Each of the catch assemblies has an upper surface oriented orthogonally to horizontal and flex upon impact by falling fruit.

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.

A shaker device including at least one motorized member that is intended to transmit by contact a shaking force to objects to be shaken. The member includes a plurality of structural inserts that are covered by a wear jacket. Each of the structural inserts has respective left lobes and right lobes. The inserts are distributed in the jacket so as to form a respective discrete stack of left lobes and right lobes.

A walking power control system for wolfberry picking, including a frame, a turntable, rotating rods, first gears, second gear, gear racks, supporting rods, hydraulic motors, a front traveling wheel, a left traveling wheel and a right traveling wheel. Hydraulic motors rotate to drives three traveling wheels to rotate, thereby driving the frame to move, when it is necessary to turn, a turntable is rotated, the turntable rotates to drive two first gears to rotate, and the two first gears rotate to drive the supporting rods to rotate, thereby driving the left traveling wheel and the right traveling wheel to rotate, so that the traveling direction of the frame is changed.

Disclosed is a portable telescopic push-pull vibrating-shaking type Camellia oleifera fruit picking and beating machine. The machine includes a picking and beating head, a gear shifting mechanism, a power transmission and picking and beating rod, a direct current motor, a control system, a handheld grip, and a lithium battery. A battery supplies power to enable the direct current motor to rotate, the direct current motor drives a worm and worm wheel mechanism in the gear shifting mechanism to rotate through a power transmission rod, the worm and worm wheel mechanism drives the picking and beating head to achieve reciprocating push-pull motion, such that the picking and beating rod can pull a branch to generate push-pull and vibration to pick Camellia oleifera fruit down. The picking and beating head is provided with a force sensor capable of monitoring picking and beating strength at any time.
