Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ground scale, more specifically, it relates to a forestry investigation ground scale of adjustable height. BACKGROUND

[0002] The forestry investigation ground scale is a tool specially used for measuring and recording forestry resource data, and is widely used in forest resource investigation and management. It is usually used to measure the diameter, height, distance and other key parameters of trees, helping investigators to obtain accurate forest resource information. Through the ground scale, investigators can mark the sample plot position, measure the tree spacing, record the terrain changes, and provide reliable basis for subsequent data analysis and forest planning. It is an indispensable tool in forestry investigation.

[0003] The traditional ground scale can only measure a single item during forestry investigation, such as measuring the height or distance of a tree alone, and cannot measure multiple parameters simultaneously. This single-function limitation makes investigators need to change tools or adjust measurement methods multiple times during forestry resource data collection, which not only increases the workload, but also reduces the work efficiency. Especially in large-scale forest investigation, this inefficient measurement method will significantly prolong the investigation time and affect the overall work progress.

[0004] On the other hand, forestry investigation is often carried out in areas with complex terrain, where the ground flatness varies greatly, and there may be slopes, unevenness or vegetation coverage. The traditional ground scale often has difficulty in maintaining verticality and stability when dealing with such complex terrain, especially in areas with steep slopes, the ground scale is prone to tilt or slide, which affects the accuracy of the measurement results. In addition, the lack of stability of the ground scale may also require repeated adjustment during the measurement process, further reducing the work efficiency. SUMMARY
