A tree breast height measuring device and measuring method

Abstract

A tree diameter measuring device and method, wherein the tree diameter measuring device comprises a main housing, a pair of clamping arms which can be synchronously opened and closed and one end of each clamping arm is rotatably assembled to the main housing, each clamping arm comprises a position indicating assembly arranged at the front end, the position indicating assembly is used to constrain the tangent point of the clamping arm and the tree trunk, so that the clamping arm is perpendicular to the tree trunk at the contact point, an angle bisector arm is arranged between the pair of clamping arms and can reciprocatingly move along a straight line and is penetratedly assembled to the main housing, the angle bisector arm comprises an indicating rod arranged at the front end of the angle bisector arm body, the indicating rod is vertically arranged relative to the angle bisector arm body, a sensing assembly is assembled to the shape change spring sheet, and a laser range finder is assembled to the main housing and is electrically connected with the sensing assembly. The tree diameter measuring device and the use method of the tree diameter measuring device can improve the ranging accuracy and the work efficiency.
