The invention provides a fruit picking method.A picking head is eccentrically driven by outputting rotating motion, so that fruit tree branches and fruits swing, inertia forces produced by the fruits due to the swing can be between the bonding forces of mature fruits and non-mature fruits and the branches by controlling the speed of the picking head outputting the rotating motion and / or a distance / eccentric distance from a rotary center, and it is ensured that the non-mature fruits are not shaken off when the mature fruits are effectively picked.The invention further provides a picking device.The picking device comprises the picking head and a power device, wherein the picking head comprises a picking head unit, the picking head unit comprises a housing, an eccentric cylinder cam mechanism and a combing tooth mechanism, and a drive shaft is positioned and supported on the housing.The eccentric cylinder cam mechanism comprises a cylinder cam and a swing rod, wherein the cylinder cam is eccentrically arranged on the drive shaft, the swing rod is connected with the cylinder cam on a closed motion trajectory structure on the cylinder cam in a slidable mode, one end of the swing rod is connected with the housing through a spherical hinge, and the swing rod extends out of the housing to be connected with the combing tooth mechanism.The method and the device are high in picking efficiency and are suitable for picking operations in orchards in hilly and mountain areas.

The invention discloses a three-string movable tooth transmission mechanism and a reducer thereof. The three-string movable tooth transmission mechanism includes a drive shaft, a tuning wire wheel, a shock wave string wheel, a moving string wheel and a movable tooth. The centerline of the tooth profile where the movable tooth center of the three-string movable tooth transmission mechanism is located is three chord lines, and a plurality of movable teeth are arranged between the chord line tooth profiles on the tuning wheel, the shock wave string wheel and the moving string wheel, each The centers of the movable teeth are simultaneously set on the tooth profile centerlines corresponding to the three chord line tooth profiles. The transmission principle of the present invention is different from the existing string movable tooth transmission, and the calculation expression of the reduction ratio can be accurately determined. Moreover, under the condition that the reduction ratio is constant, the number of movable teeth of the single-stage mechanism is increased compared with the number of movable teeth in the existing chordal movable tooth transmission mechanism, thereby improving the bearing capacity and making the output torque more stable.
