Abstract
The utility model relates to a measuring device for tree diameter, comprising a measuring component, a supporting rod and a digital display. The distance between two clamping claws can carry out photoelectric conversion through the movement of the movable clamping claws and the movement of an inner side toothed rack and a gear, and the distance can be displayed on the digital display. In this way, the diameter of a tree to be measured can be measured accurately and conveniently, the bulky labor of artificial climbing measurement is omitted, the error is few, the efficiency is high, and the utility model is suitable for using in forestry research department.
Description
The utility model belongs to the measurement equipment.
Measure the diameter of trunk eminence and the object distance of other position higher position, take the method for manual measurement always, waste time and energy, and efficient is low, and the diameter of each section of employing camera trunk that has now is because camera lens has scale, just can calculate the diameter of captured part according to photographic scale, this method has improved efficient, but data of being calculated and actual diameter error are bigger, and general error is more than 10mm.
The purpose of this utility model is that design a kind ofly can be measured trunk diameter more accurately, rapidly, used again, trunk diameter measuring appliance easy to carry.
This trunk diameter measuring appliance is made up of main body measuring appliance, support bar and device for digit-displaying three parts, 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 gearing mesh be loaded on the inboard tooth bar of a guide rail, 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 trunk diameter measuring appliance 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.
