The invention provides a high-frequency transverse vibration type drill rod. The drill rod comprises a drill rod body, a vibrator and a transverse vibration conversion device, wherein the vibrator and the transverse vibration conversion device are arranged in the drill rod body; the transverse vibration conversion device comprises a fixing assembly, a hollow gear shaft, a coil device, a permanent magnet eccentric block arranged on the hollow gear shaft in a sleeving mode and a transmission assembly connected with the hollow gear shaft and used for transverse reciprocating operation of the impact block. The invention aims to realize high-frequency transverse vibration in a mode of combining electric energy and mechanical energy. 本发明提出一种高频横向振动式的钻杆，所述钻杆包括：钻杆本体和设置在钻杆本体内的振动器、横向振动转换装置；所述横向振动转换装置包括固定组件、空心齿轮轴、线圈装置、套设在空心齿轮轴上的永磁体偏心块和与空心齿轮轴连接且用于撞击块横向往复运行的传动组件。本发明旨在通过电能与机械能相结合的方式实现高频横向振动。
