Abstract
The utility model relates to a plant sample instrument technical field especially relates to a foldable multi -functional sample prescription frame, including four end to end's main deckle board, wherein seting up symmetrical water flat groove on two relative main deckle board inner walls, arrange the spaced apart draw -in groove that is equipped with the symmetry of water flat groove equidistance of symmetry the sample prescription inside casing that the joint comprises the diaphragm handed over by a plurality of horizontal strokes, longitudinal phase and vertical plate in the draw -in groove of symmetry. Because of application of the technical solution, the utility model discloses not only being fit for taking a sample on a large scale, also being fit for among a small circle, the multidraw, the sample effect is better. And this application is convenient for assemble, dismantle, and the sample range adjustment is swift, and especially adapted field is carried, is used.
Description
Technical field
The utility model relates to plant sampling instrument technical field, is specifically related to a kind of folding utility sample prescription frame.
Background technology
Sample prescription, i.e. square sample plot, being modal form in area sampling, is also use the most general a kind of sampling technique in vegetation investigation.The size of sample prescription, shape and number, depend primarily on the character of studied group and the academic thinking of employing.Usually, group is more complicated, and sample area is larger; The number of sampling is generally no less than 3, and sampling number is more, and sampling error is less.When a lot of teaching, R&D institution carry out the scientific research about the aspect such as ecological construction and meadow, measure, analyze the Species Structure of plant, output, quadrat method will be adopted to conduct a research in unit area work.
Chinese invention patent 200910079979.5 " draft sample ground cover degree, point cover degree measuring apparatus " provides the draft sample ground sample prescription defining method of a kind of sample prescription framework and slidingtype punch block composition.Utility model patent CN203249646U " a kind of measurement mechanism of herbosa " provides the sample prescription assay method of a kind of fixed sample prescription frame and dismountable stay cord formation.CN203629923U " device laid by a kind of herbosa sample prescription " adopts the dividing strip composition sample prescription of square frame and different size to lay device.Above-mentioned patented method can precisely determine sample prescription specification, but inconvenience is carried in existence, dismounting is complicated, is unfavorable for the problem of the various some investigation in field.
Summary of the invention
The purpose of this utility model is that, for above-mentioned Problems existing with not enough, proposition one is easy to carry, assembles, and can change the folding utility sample prescription frame of sampling scope according to actual needs fast.
The purpose of this utility model is achieved in that folding utility sample prescription frame, comprise four end to end main deckle boards, two relative main deckle board inwalls offer symmetrical level trough wherein, level trough equi-spaced apart along described symmetry offers symmetrical draw-in groove, is connected with the sample prescription inside casing be made up of the transverse slat of some horizontal strokes, longitudinal phase friendship and stringer board in the draw-in groove of described symmetry.
Due to implement technique scheme, the utility model be not only applicable to samples on a large scale, be also applicable among a small circle, multidraw, sampling better effects if.And the application is convenient to assembling, dismounting, the adjustment of sampling scope is quick, is applicable to very much field and carries, uses.
Accompanying drawing illustrates: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is folding utility sample prescription mount structure schematic diagram.
Legend: 1, draw-in groove, 2, level trough, 3, main deckle board, 4, connector, 5, transverse slat, 6, transverse slat draw-in groove, 7, stringer board draw-in groove, 8, stringer board.
Detailed description of the invention: the utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, folding utility sample prescription frame comprises four end to end main deckle boards 3, two relative main deckle board 3 inwalls offer symmetrical level trough 2 wherein, level trough 2 equi-spaced apart along described symmetry offers symmetrical draw-in groove 1, is connected with the sample prescription inside casing be made up of the transverse slat 5 of some horizontal strokes, longitudinal phase friendship and stringer board 8 in the draw-in groove 1 of described symmetry.
Described transverse slat 5 two ends are convex falcon structure, and described convex falcon snaps in aforementioned draw-in groove 1, make transverse slat 5 and the clamping of main deckle board 3.
Described transverse slat 5 is equally spaced and is provided with transverse slat draw-in groove 6, described stringer board 8 is equally spaced is provided with the stringer board draw-in groove 7 of clamping corresponding to transverse slat draw-in groove 6.
Described transverse slat draw-in groove 6 is the open slots offered downwards by transverse slat 5 upper end, and described stringer board draw-in groove 7 is the open slots upwards offered by stringer board lower end.
Spacing between draw-in groove 1 adjacent is between two 10cm-20cm, and the spacing between transverse slat draw-in groove 6 adjacent is between two 10cm-20cm, and the spacing between stringer board draw-in groove 7 adjacent is between two 10cm-20cm.
Described connector 4 can adopt the multiple turntable such as hinge, rotating shaft, as long as ensure can carry out between main deckle board 3 folding.
During use, first main deckle board 3 is launched, make it be after square, some transverse slats 5 are snapped in corresponding draw-in groove 1 by demand, thus determine sample prescription width, subsequently the stringer board 8 of identical number is snapped in corresponding transverse slat draw-in groove 6, after transverse slat 5 and stringer board 8 are intersected, produce some square sample frames.
Two of optional position and with after upper cross plate 5 and the clamping of main deckle board 3, can ensure that four main deckle boards 3 keep rectangle or square and indeformable, guarantee the accurate of sampling scope.
Above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease inessential technical characteristic according to actual needs, meet the needs of different situations.
