Problems solved by technology

[0004] (1) The measurement of tree crown width is generally measured remotely by a ruler or a laser rangefinder. The ruler measurement method has terrain restrictions, and the method of measuring and calculating by a laser rangefinder needs to adjust the laser rangefinder to a horizontal state every time, which is troublesome to operate.
[0005] (2) When measuring the crown width of the tree with the laser rangefinder, it is operated from a certain side of the tree every time. Compared with the method of vertical measurement directly below the tree, no matter the measurement is performed from any side, the observed crown The frames are covered, so the accuracy of the measurement cannot be achieved
[0006] (3) The existing laser range finder drives the instrument to adjust the angle through gear transmission. This method is very inefficient in adjusting the angle, resulting in slow measurement

Abstract

The invention relates to the technical field of arbor crown breadth measurement, in particular to an arbor crown breadth rapid measuring device which comprises a laser range finder, a sliding table is arranged at the bottom of the laser range finder, an arc-shaped adjustable track is connected to the middle of the sliding table, sliding barrels are connected to the two ends of the adjustable track respectively, and ruler rails are slidably connected to the middles of the sliding barrels; and the sliding table is provided with a rapid leveling platform plate and a locking block, the top of the rapid leveling platform plate is provided with an angle rapid adjustment support, and the laser range finder is arranged on the angle rapid adjustment support. The laser range finder can be supported through the sliding table, so that the laser range finder can move along an arc-shaped adjustable track. The crown breadth of the arbor is measured at multiple angles on the same horizontal plane and at the same distance away from the trunk of the arbor, so that the problem that the visual field is shielded due to measurement at a fixed position can be avoided, and the measurement data is more accurate through convenient and repeated measurement.

Description

technical field [0001] The invention relates to the technical field of arbor crown width measurement, in particular to a rapid measurement device for arbor crown width. Background technique [0002] The crown can reflect the maximum width of the tree in the horizontal direction and the projected area on the ground, reflecting the growth of the tree. The tree body of the tree is relatively tall, usually as high as six meters to tens of meters [0003] In the prior art, there are the following problems in the measurement of trees: [0004] (1) The measurement of tree crown width is generally measured remotely by a ruler or a laser rangefinder. The ruler measurement method has terrain restrictions, and the method of measuring and calculating by a laser rangefinder needs to adjust the laser rangefinder to a horizontal state every time, which is troublesome to operate. . [0005] (2) When measuring the crown width of the tree with the laser rangefinder, it is operated from a ce...
