Description
Technical field
The utility model belongs to trees branch measuring apparatus field; Be specifically related to Portable tree crotch angle measuring instrument.
Background technology
The apparatus derivatorius of trees is the emphasis of Crown Structure research always.The branch of trees and spatial variations feature thereof are the principal elements that determines trees and shape of tree-crown.After 20 century 70s, people start the apparatus derivatorius of trees to study widely, wherein the branch progression of branch, branching pattern, crotch angle and spatial configuration state thereof, not only directly determined tree crown size and shape, also affects the space distribution of bud and leaf.
Crotch angle is an important factor in Crown Structure, and it plays a part decision row to crown formation, is also an important indicator weighing plant space distribution capability, and its capacity to spatial spread branches and leaves to illumination, temperature, CO
2the space distribution of utilizing machine different component biomass.
At present, the instrument report of measuring about trees crotch angle seldom.
Summary of the invention
The utility model object has been to provide Portable tree crotch angle measuring instrument.
Portable tree crotch angle measuring instrument, it comprises fixed ruler and semicircle protractor, and one end of fixed ruler is provided with semicircle protractor, and one end that semicircle protractor center and first turns chi is connected by the first fastening bolt; First other end that turns chi is provided with the first circular protractor, the first circular protractor center is connected by the second fastening bolt with second one end that turns chi, second other end that turns chi is provided with the second circular protractor, and the center of the second circular protractor and the 3rd turns chi and is connected by the 3rd fastening bolt.
Semicircle protractor is provided with the first fan-shaped pylone, facilitates hand-held.
Uniform 3 the second fan-shaped pylones of the first circular protractor, facilitate hand-held.
The second uniform 3 of circular protractors the 3rd fan-shaped pylone, facilitates hand-held.
When measurement, operator, by range estimation, by parallel with trunk fixed ruler placement, then adjusts first and turns chi, makes it parallel with the branch on trunk, fastening with the first fastening bolt; Then adjust the second motion bar, make it parallel with next branch, fastening with the second fastening bolt; Adjust the 3rd motion bar again, make it parallel with next branch, fastening with the 3rd fastening bolt, reading angular value, obtains crotch angle, for research Crown Structure provides accurate data.
Of the present utility model simple in structure, easily processing, easy to use, collapsible, conserve space, is easy to carry.
