Description
Technical field
It the utility model is related to a kind of measuring forest device, more particularly to a kind of Portable tree tree breast diameter survey device.
Background technology
In current forest assessment and Forestry Investigation research, tree breast-height diameter is an index of necessary investigation.
Present tree breast-height diameter mainly with diameter of a cross-section of a tree trunk 1.3 meters above the ground tape measure carries out manual measurement, it is necessary to by the circular trunk of tape measure, for trunk compared with
Thick trees, even two people are needed to assist during measurement, operation inconvenience.And human hand inevitably contacts with trunk when measuring,
It is subject to worm ant to bite, while manually reads scale, also easily produces error.So the precision and efficiency of traditional measurement mode
All it is difficult to ensure.
Although having there is the instrument for measuring tree diameters, e.g., including support bar and two kellies for opening 60 °, swash
Bisector of angle is opened in the Laser emission direction of ligh-ranging probe towards two kellies, and support bar is where two kellies
The distance between plane, the laser ranging probe for measuring to obtain to trees is the radius of trees to be measured.But this kind of measuring instrument
Angle between two kellies of device is integrally fixed at 60 °, if changing its measurement angle, can not realize the survey of tree diameters
Amount.And the diameter distribution of trees to be measured is larger, if during the measurement larger trees of the diameter of a cross-section of a tree trunk 1.3 meters above the ground, by the angle between two kellies
Be fixed on 60 °, by two kellies and trees it is tangent when, then need kelly that there is larger length, it has not been convenient to carry；And if surveyed
When measuring the less trees of diameter, the length of kelly is larger, it has not been convenient to operates, a people is difficult to complete measurement, influences the standard of measurement
Exactness.In addition, it is necessary to ensure that the laser direction of laser ranging probe opens positioned at two kellies when being measured using the device
On bisector of angle, if laser direction is slightly offset, the accuracy of detection will be had a strong impact on, so the essence to instrument manufacturing
Density requirements are strict, substantially increase the manufacturing cost of instrument.
Other tree breast diameter survey instruments are larger there is also volume, it is difficult to carry out the standard of diameter to the trees of larger diameter distribution
Really measurement, meanwhile, the factor for influenceing tree diameters measurement accuracy is more, it is difficult to ensures the accuracy of measurement.
In summary, the tree breast diameter survey equipment instrument of trees is larger in the prior art, inconvenient carrying, it is difficult to larger straight
The problem of trees of footpath distribution carry out the accurate measurement of diameter, still lacks effective solution.
