Pineapple picking apparatus

The invention provides a pineapple picking apparatus, comprising a body unit, a picking unit and a control unit. The picking unit comprises: a mounting frame connected with the body unit; a picking claw movably mounted on the mounting frame; a driving source connected with the control unit and driving the picking claw to move back and forth between an initial position and a stop position; a rotaryshaft having two ends supported on the mounting frame through torsion springs; a retaining plate mounted on the rotary shaft and which initially limits the picking claw from moving to the stop position from the initial position; and a collecting plate having one end positioned below the stop position, wherein with movement of the body unit, when the retaining plate gains contact with a pineapple,the retaining plate is pushed by the pineapple so that the rotary shaft rotates around its axis; after the pineapple is picked by the picking claw, the picking claw moves to the initial position, andthe retaining plate return
