Tree age non-destructive measuring device based on stress wave technique

The utility model relates to a device capable of non-destructively measuring the age of living trees, and aims to provide a device with the characteristics of high measuring precision, high detection efficiency and no radiation, and convenient use and lower cost. The technical scheme is that: the tree age non-destructive measuring device based on the stress wave technique comprises two bolts, a pulse hammer, a starting sensor, a terminating sensor and a detection system, wherein the bolts are used for being embedded in a measured tree, and the pulse hammer is used for striking the bolts; and the starting sensor and the terminating sensor are respectively and electrically connected with the bolts by leads, and the detection system is respectively communicated with the starting sensor and the terminating sensor by data cables. The detection system is of a waveform analyzer.
