Abstract
Optoelectronic range finder for measuring trunk diameter.Form by main body measuring appliance, support bar and device for digit-displaying three parts.The main body measuring appliance is made up of measurement component and counter block, the people is on the ground by handling moving of rope control activity jaw, the opto-electronic conversion mechanism of counter block shows trunk diameter by device for digit-displaying, can make things convenient for, measure rapidly the different-diameter of tested each section of trunk, it is little to have error, the characteristics that efficient is high are for forestry scientific research, production mechanism provide desirable scientific research equipment.
Description
The utility model belongs to forestry scientific research equipment.
Need periodic measurement trunk growth diameter in the forestry scientific research, the past, labor capacity was big to the measurement of then need manually climbing tree of tall and big trees, and efficient is low.Present more employing photogrammetric method, the camera that promptly adds scale with the camera lens band, take tested each section of trunk diameter, calculate its actual diameter according to photographic scale then, this method has improved measuring and calculating efficient, but error is bigger, error is generally more than 10mm, and the employing method of geometry that also has is tabled look-up according to the height of tree, angle and to be calculated, do more loaded down with trivial detailsly, error is also more than 6mm.
The purpose of this utility model provides a kind of easy to use, can measure the scientific research trunk diameter stadimeter of trunk diameter again rapidly accurately.
This optoelectronic range finder for measuring trunk diameter partly is made up of main body measuring appliance, support bar and device for digit-displaying three, and the main body measuring appliance is made of distance member and counter block, and distance member comprises two garden tubular guide rails; The web joint that connects two guide rails; Be fixed in a stationary jaw on the web joint; Two guide pin bushings that can on two guide rails, move; Two guide pin bushings also have a plate to connect, a fixing movable jaw that can on guide rail, move by guide pin bushing on this web joint, movable jaw move through two deflection sheavies and the two top ropes controls that are fixed on the web joint bottom.Counter block is by being fixed in axle sleeve, support on the web joint, being loaded on a gear in the axle sleeve, and with the inboard tooth bar that is loaded on a guide rail inboard of gearing mesh, a unthreaded hole dish is fixed in the gear lower end, the unthreaded hole plate edge is equipped with a photoelectric tube.Support bar is fixed in main body measuring appliance bottom, is connected with fixed head, the main body measuring appliance can be propped up.The photoelectricity device for digit-displaying that device for digit-displaying is made up of integrated package, charactron, triode, diode and a plurality of resistance capacitance element is positioned over ground, is connected with photoelectric tube with lead, gets final product video data.
This optoelectronic range finder for measuring trunk diameter is lifted the main body measuring appliance by support bar, main body measuring appliance weight has only about 2 kilograms, therefore can measure each section of trunk diameter easily, again owing to be directly to clamp the trunk both sides by control rope control activity jaw, count by counter block again, and directly demonstrate data by device for digit-displaying, thereby rapidly, accurately, error is only about 1mm.For forestry at different levels scientific research institution, production unit provide a kind of desirable measurement equipment.
