The finger row frame is arranged along a vertical plane. The four sliding blocks are respectively installed on the two optical axes in a sliding mode in pairs, so that the finger row frame is positioned on the two optical axes. A plurality of finger board are horizontally fixed (preferably in a bolt fixing mode) on the finger frame; a plurality of the finger bars are fixed on the finger board through the optical axis fixing ring 305, and the finger bars extend outwards perpendicular to the plane of the finger frame. The distance between the adjacent finger row plates and the adjacent finger row rods can be set according to actual conditions in a user-defined mode so as to adapt to oil tea tree trees of different types and different densities. The fingerboard rods are arranged in a wave shape to increase the excitation area of the fingerboard rods. The finger row rods on two adjacent finger row plates are arranged in a staggered mode to enhance the vibration excitation effect. When the device works, the vibration excitation device can horizontally move along the optical axis, the optical axis can vertically move along the guide rail, and the superposed motion track is the elliptic motion track of the vibration excitation device.
