ELECTRIFIC DEVICE FOR SHAKING CEDAR CONES FROM TREES Russian patent published in 2022 - IPC A01D46/26 

FIELD: forestry.

SUBSTANCE: invention relates to the field of forestry. The device comprises a vehicle with a platform on wheels with a shaker pivotally mounted on it, consisting of an actuating element with a telescopic rod, and a cabin. The cab is located on a platform mounted on motor-wheels and equipped with an engine compartment, in the body of which an internal combustion engine and a generator are installed. At the corners of the platform there are four screw jacks with a ball screw drive controlled by an electric drive to ensure the balance of the device on an uneven surface. As the acting element of the shaker, a vibrator is used, containing vibrating elements installed inside its housing in the form of a worm gear, consisting of a drive gear fixed in the housing on two support bearings and two driven gears with their own axes of rotation and symmetrical masses of unbalances by a drive shaft, frequency controlled by an electric motor located on the body of the vibrator, on top of which there is a video camera. The telescopic rod is pivotally connected to the body of the engine compartment using an electric actuator. On the lower side surface of the rod there is a control unit for its direction and length. The upper part of the telescopic rod is connected to the body of the vibrator, placed on horizontal guides, and is equipped with two-axis reversible electric drives for vertical rotation and horizontal movement. The shaker has a device for gripping a tree trunk, made of at least three arcuate plates interconnected with the possibility of rotation in a horizontal plane. The outermost of the plates are pivotally connected by means of electric linear mechanisms to the vibrator body, and the middle one is fixedly connected to it at the location of the support bearing for the drive shaft.

EFFECT: increased productivity and quality of harvesting fruits.
