The invention provides a lateral-crossing vibration exciting type berry harvester. A plurality of vibration exciting devices can be hung on the harvester laterally. The harvester is mainly used for mechanized continuous harvesting of wolfberry, height and harvesting amplitude of the vibration exciting devices can be adjusted to meet requirements on efficient continuous harvesting of fruits on berry fruiters different in height and line spacing, and cherry harvesting of two rows of the berry fruiters can be completed through one harvesting operation; the harvester comprises a rack arranged on atraveling device, a pair of supporting guide plates oppositely arranged in the rack through vertical movement of a supporting guide plate moving device, a main vibration exciting frame arranged on the supporting plates through transverse movement of a vibration exciting frame moving device along the traveling device, vibration exciting brushes with inwards-concave middles arranged in the main vibration exciting frame and an auxiliary vibration exciting frame through up-down vibration of the vibration exciting devices, a main berry collection box arranged on the traveling device, an auxiliaryberry collection box arranged below the auxiliary vibration exciting frame and used for temporarily containing berries and conveying devices detachably arranged on two sides of the traveling device and used for carrying and conveying the berries to the main berry collection box.
