The invention relates to an anchor rod anchoring quality detector, and belongs to the non-destructive test technical field. The detector comprises a central control module, a guided wave excitation module, a power amplification module, a channel switching module, a signal conditioning module, a data acquisition module, a user interaction module, a rechargeable battery module, a power adapter and a guided wave transceiving transducer. The detector adopts high-frequency and low-frequency guided wave dual-mode detection, and can comprehensively evaluate the anchor rod anchoring quality. The detector has simple operation, can display detection results in real time, can be manufactured into a plurality of modes such as a portable type, a vehicle-borne type, a stationary type and the like, and facilitates working personnel to be capable of rapidly detecting the anchor rod anchoring quality in practical engineering.
