Abstract
Disclosed in the utility model is a simple measuring device for an increment of a diameter at breast height of a tree. The simple measuring device comprises a flexible ruler with scales and a steel wire. Installing holes are respectively arranged at the two ends of the flexible ruler; the front end of the steel wire and the front end of the flexible ruler are fixedly connected; and the steel wire is tightened and successively wraps around a to-be-tested tree and the flexible ruler. And a mark is arranged at the steel wire and is overlapped with the initial scale at the front end of the flexible ruler. With the simple measuring device, the increment of the diameter at breast height of the tree can be known simply and conveniently; and the measurement is not influenced by the tree shape and the environment. The device with the simple structure can be manufactured conveniently and can be popularized conveniently in a large range.
Description
Technical field
The utility model relates to a kind of measurement mechanism of arboreal growth, in particular a kind of Simple measurement device of trees breast diameter growth amount.
Background technology
The measurement of trees breast diameter growth amount is used diameter of a cross-section of a tree trunk 1.3 meters above the ground tape measure to carry out all the time, is mainly to take year as chronomere's understanding trees breast diameter growth amount, but affected by the factors such as human factor, measuring position and arboreal growth speed, and accuracy is lower.In recent years, in carrying out the solid carbon potentiality research topic of trees, need accurately to understand the trees diameter of a cross-section of a tree trunk 1.3 meters above the ground half a year of Growth even, measure early stage with growth ring, its result of use on broad leaf tree and China fir treelet is fine, but finds for the quick growing species of trees and thicker, the soft aged trees of bark faster of growing, and growth ring can embed in bark, cause measurement inaccurate, bring greater impact to the assessment in later stage.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of Simple measurement device of trees breast diameter growth amount is provided, and realizes measuring comparatively accurately trees breast diameter growth amount.
The utility model is achieved through the following technical solutions, the utility model comprises is with graduated tape and steel wire, the two ends of described tape are respectively equipped with mounting hole, the head end of steel wire and the head end of tape are fixedly linked, Wire pulling also is wrapped on trees to be measured and tape successively, steel wire is provided with mark, the start index position overlaid of described mark and tape head end.
In order to prevent that steel wire is by rain erosion, described steel wire is provided with the antirust plastic sleeve pipe.
As one of optimal way of the present utility model, described gauge of wire is 0.1cm, and the diameter of described antirust plastic sleeve pipe is 0.25cm.
The head end of described steel wire is circular ring structure, and steel wire is wrapped in after trees to be measured and tape successively through the circular ring structure of steel wire head end, can conveniently place steel wire.
The utility model has the following advantages compared to existing technology: the utility model can be understood the increment of the trees diameter of a cross-section of a tree trunk 1.3 meters above the ground simply and easily, is not subject to the impact of tree type and environment, simple in structure, easy to make, is convenient to promote on a large scale.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, the present embodiment comprises is with graduated tape 1 and steel wire 2, the two ends of described tape 1 are respectively equipped with mounting hole 11, the head end of the head end of steel wire 2 and tape 1 is fixedly linked, steel wire 2 tensions also are wrapped on trees to be measured and tape 1 successively, steel wire 2 is provided with mark 21, the start index position overlaid of described mark 21 and tape 1 head end.In order to prevent that steel wire 2 is by rain erosion, described steel wire 2 is provided with the antirust plastic sleeve pipe.
The diameter of described steel wire 2 is 0.1cm, and the diameter of described antirust plastic sleeve pipe is 0.25cm.
The head end of described steel wire 2 is circular ring structure 22, and steel wire 2 is wrapped in trees to be measured and the rear circular ring structure 22 through steel wire 2 head ends of tape 1 successively, can conveniently place steel wire 2.
During use, the mounting hole at the two ends of tape 1 11 is fixed on trees to be measured by nail, after steel wire 2 head ends are fixing, through the antirust plastic sleeve pipe, then after straining and be wrapped in trees to be measured and tape 1, circular ring structure 22 through steel wire 2 head ends gets final product, and can roughly draw according to the displacement of mark 21 increment of trees, as need are accurately measured and again steel wire 2 taken off with vernier caliper measurement and gets final product.
