Hard fruit picking mechanical head device

The invention discloses a hard fruit picking mechanical head device which can solve the technical problems that an existing hard fruit picking head is complex in structure, high in production cost andthe like on the premise that hard fruit picking and grabbing are stable. The picking head is provided with expandable fingers, each finger is composed of a picker body and a driven sliding rod, the fingers are fixed through the driven sliding rods and then installed on a palm disc, and a transmission rope drives the fingers to work by being connected with mechanical holes in the driven sliding rods. The transmission rope controls the fingers to work through a motor driving device connected with the palm disc. According to the hard fruit picking head, the fingers are driven to be folded through motor driving and rope transmission, the two expanding fingers are driven by the relatively small motor to complete picking of hard fruits, and compared with a common hard fruit picking head, the fruit picking head has the
