AI Technical Summary

Technical Problem

The existing tree breast diameter measurement device is troublesome and difficult, especially when installing springs, it requires complicated steps, which is laborious and inconvenient.

Method used

An automatic detection instrument for tree breast diameter is designed, using a flexible steel strip ruler and fixing assembly. One end of the strip ruler is connected to the fixing device, and the fixing device includes a mounting shell, a fixing assembly and a coil spring. The fixed teeth on the fixing wheel snap into the groove of the steel strip ruler, and the coil spring is used to prevent the steel strip ruler from slack, achieving continuous automatic measurement.

Benefits of technology

The operation process of tree breast diameter measurement is simplified, making measurements easier and more convenient, avoiding the complexity and laboriousness of existing devices during installation, and achieving continuous automatic measurement of tree trunks.

Abstract

The utility model relates to the technical field of measurement, and discloses an automatic detection instrument for the diameter at breast height of a tree, which comprises a flexible steel belt ruler, one end of the steel belt ruler is connected with a fixing device, and the fixing device comprises a mounting shell and a fixing assembly; a penetrating opening for the other end of the steel belt ruler to penetrate through is formed in the mounting shell, a mounting cavity for mounting the fixing assembly is formed in the mounting shell, and the mounting cavity is located above the penetrating opening and communicated with the penetrating opening; the fixing assembly comprises a fixing wheel, a mounting frame and a coil spring. When the diameter at the breast height of a tree trunk is measured, the steel belt ruler is tightly attached to the tree trunk and surrounds the tree trunk by a circle and then penetrates through the through hole, then the fixing assembly is pressed down, the fixing teeth on the fixing wheel are clamped into the tooth grooves of the steel belt ruler, and the steel belt ruler can be prevented from loosening under the action of the coil spring; the trunk can be continuously and automatically measured by means of the deformation quantity of the coil spring in the growth process, and the whole operation is simpler and more convenient.
