Description
Technical field
The utility model relates to the tree ring analytical equipment, specifically is a kind of tree ring and material detection analysis instrument.
Background technology
Tree wheel chronology (Dendrochronology) is also named the tree wheel fixed year (Tree-ring Dating), is the research to the tree ring chronosequence.The tree of science wheel chronology be astronomical scholar's Douglas (Douglass) doctor of the U.S. in earlier 1900s research set up.Tree ring is natural information bank.The research of tree ring is for the reconstruction of historical informations such as fixed year, nature weather, the hydrology, pollution, earthquake, geology, medical science, and the prediction that reaches aspects such as following nature weather, the hydrology, earthquakes plays crucial effects.Information that tree ring contained use additive method can not obtain.
Along with science and technology development, the detection analysis of trees material has been developed into higher level.As " the RESISTOGRAPH trees Zhen Measuring instrument " that Germany produces, by the pin that ridicules of computer control electronic sensor, measure the impedance that pierces of timber or trees, the inner structure of utilizing the software analysis trees is as rotten or empty situation, material status, upgrowth situation.It is applied to the detecting, trees of shade tree, park ancient tree and forest, dangerous trees or timber is corrupt and the discovery of wooden defective, trees year growth rate the state-detection such as wooden evaluation, wooden building, column of measurement, trees or timber.German in addition " the PiCUS that produces
Trees tomography portrait diagnostic device ", this Device Testing principle is based on healthy and the impaired trees transport properties different to sound.By integrating the velocity of propagation of each measurement gained, just can draw the sound of whole trunk xsect, the routine analyzer sound property that the trunk xsect is different that passes to PICUS comes out with different color showings.And it is whether healthy by distinguishing that different color relations can draw trees." RESISTOGRAPH trees pin is surveyed instrument " and " PiCUS
Trees tomography portrait diagnostic device " can survey the material status of trees, but can not survey tree ring.
The at present domestic method that the detection of tree ring is used always is the felling by trees, perhaps takes a sample with growth cone.Carry out the research of trees with growth cone, comparatively speaking relatively accurately, but carry out the statistical research of big regional trees, not only the manpower and materials requirement is bigger, and uses growth cone that the inconvenience part is arranged.Diameter as growth cone is bigger, and is bigger to the infringement of trees.The trees bigger to diameter go into to have any problem with the manpower rotary drill.Especially to ancient tree wood, bigger infringement is unallowed.Obtain annual ring information with trees felling and growth cone, especially the detection to ancient tree wood annual ring has been subjected to very big restriction.This has also limited obtaining of ancient tree wood annual ring information to a great extent, has limited the annual ring information of ancient times phase is rebuild.Ancient tree annual ring information is much more important than modern tree ring information.
Summary of the invention
The purpose of this utility model provides a kind of tree ring and material detection analysis instrument, material that can not only the detection analysis trees, and can survey tree ring, accurately determine the age of trees.
The utility model is achieved by the following technical solution: a kind of tree ring and material detection analysis instrument, comprise be used to thrust in the trees by drill bit and. drive the rig that the direct current motor of drill bit is formed, the augering screw that the promotion rig advances; Being equipped with between direct current generator and augering screw becomes the annual ring signal converter of analog electrical signal, annual ring signal converter to be connected with direct current motor with connecting rod the annual ring conversion of signals; Above-mentioned each parts are installed in forms detector on the guide groove; Also comprise the A/D converter and processing, demonstration, storage and the printing terminal that analog signal conversion are become digital signal; A/D converter is connected with processing, demonstration, storage and printing terminal by output line.
Principle of work is: different and greater than the characteristics of the hardness at other positions according to the hardness of each annual ring line, the resistance difference of each the annual ring line in the drill bit thorn in-tree is obtained the mechanical signal of each annual ring, convert the mechanical signal of annual ring to analog electrical signal by the annual ring signal converter, pass through A/D converter, the analog signal conversion that will contain annual ring is a digital signal, makes terminal with microcomputer the annual ring signal is handled, stores, shows, printed.
The beneficial effects of the utility model are: simple in structure, easy to use, and for ease of field work.Material that can easily the detection analysis trees is surveyed tree ring, accurately determines the age of trees.
