The invention provides a mulberry picker, belonging to the field of agricultural machinery. The mulberry picker comprises a collecting device, a rack, a power and transmission device and a traveling device. By clockwise and anticlockwise rotation of a rotary rocking bar, a transmission system can be used for controlling meshing between a gear and an arc-shaped gear rack, a collecting umbrella is opened and closed to wrap a mulberry tree to form a wrapping and encircling surface with an area of 4-5 square meters below the mulberry tree, by shaking the mulberry tree, mulberries can fall in the collecting umbrella, the collecting umbrella is used for collecting the mulberries, and the mulberries fall in a hopper through a collecting pipeline. A motor can also be used for driving a main shaftto rotate to open or close the collecting umbrella, and a motor can be used for driving the traveling device to lead a machine to advance in the field. The mulberry picker has a reasonable structure,and is easy to manufacture, when the motor is used as power in the using process, the motor speed can be adjusted to control the traveling speed of the device, in addition, the work efficiency of thedevice is dozens of times greater than artificial picking, the manufacture cost is relatively low, so that the mulberry picker is suitable for wide-range popularization.
