Abstract
The utility model discloses a vernier-caliper type angle gauge dendrometer, in order to overcome the disadvantages that the prior angle gauge dendrometer has poor adaptability, inconvenient use and low working efficiency. In the utility model, the angel gauge rod is improved to become an extensible pull rod that can be shortened or elongated, the angle gauge gap at the end of the angle gauge rod can be changed by a movable vernier caliper. The vernier-caliper type angle gauge dendrometer is used for the measurement of basal area and diameter of forest living tree, furthermore by local unitary volume table, forest volume can be worked out rapidly. The vernier-caliper type angle gauge dendrometer has the advantages of flexible and convenient use, strong adaptability, and high working efficiency.
Description
Technical field
The utility model relates to a kind of instrument that is used for forest standing tree measuring and calculating alive, is specially a kind of vernier caliper formula angle gauge tree surveying apparatus.
Background technology
Have now in the angle gauge instrument of the standing volume of living with the measuring and calculating forest, its not flexible of angle gauge bar, be installed on the card of this angle gauge boom end and only leave a changeless breach (observation back sight), the deficiency of this angle gauge instrument is produced and is, the angle gauge bar can not be flexible with gradient size, the angle gauge breach can not change along with the variation of angle gauge coefficient, use dumbly, usable range is limited, and measuring speed is slow, labour intensity is big, inefficiency.
The utility model content
The purpose of this utility model will overcome above-mentioned deficiency exactly, provides that a kind of angle gauge bar is scalable, the angle gauge breach can change, uses flexibly, applicability is strong, measuring speed is fast, labour intensity is little, the vernier caliper formula angle gauge tree surveying apparatus of high efficiency.
For achieving the above object, the technical solution of the utility model is, this vernier caliper formula angle gauge tree surveying apparatus comprises the angle gauge with angle gauge breach and is installed on the angle gauge bar at this angle gauge middle part, having installed on described angle gauge can be by moving the angle gauge vernier that changes this angle gauge breach size, and described angle gauge bar is made of at least 2 joints that can stretch.By mobile angle gauge vernier, can change the size of this angle gauge breach, to adapt to the measurement in different forest lands, improved practicality; The angle gauge bar can stretch, and use is easy to carry.
Compare with existing angle gauge tree surveying apparatus, 2 angle gauge verniers that can move about have been installed on the angle gauge of the present utility model, make the angle gauge breach of observation can be, enlarged usable range with the far and near size variation of measured tree, measuring speed is fast, labour intensity is little, work efficiency improves 50%; The angle gauge bar can stretch, and is easy to use flexible.The utility model was used for the measuring and calculating of the loose China fir 2 ten thousand stere forest lands standing tree alive in 10 townshiies, 2 counties in 2006, and accuracy of the mean is 98.6%, and work efficiency improves 50%.
Description of drawings
This accompanying drawing is the utility model structural representation.
Among the figure, 1. angle gauge, 2. angle gauge breach, 3. angle gauge vernier, 4. angle gauge bar.
Embodiment
As shown in the figure, the utility model comprises the angle gauge [1] with angle gauge breach [2] and is installed on the angle gauge bar [4] at this angle gauge [1] middle part, having installed on described angle gauge [1] can be by moving the angle gauge vernier [3] that changes this angle gauge breach [2] size, and described angle gauge bar [4] is made of 3 joints that can stretch.
During use, according to the ratio of angle gauge [1], elongation angle gauge bar [4], it is terminal by pasting lower eyelid, move angle gauge vernier [3] according to concrete forest land, determined the size and the angle gauge coefficient of angle gauge breach [2], aim at standing tree, preceding sight line is along with slope change, graticule scanning gap slot forms and cuts width mutually and aim at tested standing tree breastheight place and measure (being that conventional angle gauge tree surveying apparatus makes usage), can record forest land the live breastheight and the basal area of standing tree, look into the various places single entry volume table, draw the forest land volume of timber.
Claims (1)
1. vernier caliper formula angle gauge tree surveying apparatus, comprise angle gauge [1] and be installed on the angle gauge bar [4] at this angle gauge [1] middle part with angle gauge breach [2], it is characterized in that, having installed on described angle gauge [1] can be by moving the angle gauge vernier [3] that changes this angle gauge breach [2] size, and described angle gauge bar [4] is made of at least 2 joints that can stretch.
