The utility model provides a pair of sample prescription investigation and sample frame through setting up detachable horizontal pole, L type fixation clamp, traction rope connection spare and round bar, can satisfy sample frame sample accuracy, convenient to detach and basic function such as equipment, convenient to carry on the one hand, still can carry out the precision measurement to community's cover degree, many degree in complicated topography region or the fixed area, improves the application scope of sample frame.
Description
Technical field
The utility model relates to a kind of sampling frame, particularly a kind of sample investigation for field study and sampling frame.
Background technology
Field study is basic skills that is ecological, particularly synecology research.In ecological and botany association area, sample investigation in the past lays particular emphasis on the acquisition of some master datas, as the height of plant, frequency, cover degree etc., along with the development that the epoch are progressive and scientific and technological, current field study is not only the acquisition being confined to master data, simultaneously according to the basal cover needing meeting corresponding analysis group of investigation, biomass, the soil physico-chemical property etc. on plant growth ground, this wherein just relates to the base portion height of plant, the problems such as the spot sampling in sample prescription, in order to adapt to modern field study, thereby produce the needs to novel sample investigation and sampling frame.
The instrument being applied to sample investigation is at present mainly tape measure, cord or prefabricated wooden frame, and major defect is: 1), can not well determine sample prescription shape and fixed-area, enquiry data can be caused thus inaccurate; 2) although, prefabricated wooden frame can solid form and area, but joint is generally screw rod to be connected with nut, ensure that wooden frame can shrink and need make it movable, so very easily cause screw rod and nut to be lost in the wild, wooden frame compares effort due to heavier long-time carrying simultaneously.3), present sample investigation improves frame has and adopt contractile and aluminum, be generally speaking conducive to carrying and lightweight, but the sample prescription not possessing complex condition measures, as slope, concavo-convex etc.; Also reckon without the sampling of biomass in sample prescription and pedotheque simultaneously, cause obtaining of sample to have artificial property, cause measurement to occur relatively large deviation thus.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of sample investigation and sampling frame, can solve in existing sample investigation and carry inconvenience, sample prescription frame under complicated landform is placed and sampling is inconvenient and in sample prescription frame for problems such as cover degree of communities in fixed area, many degree measuring accuracies are inadequate.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of sample investigation and sampling frame, comprise cross bar, L-type geometrical clamp, traction rope web member and round bar, described L-type geometrical clamp two ends is equipped with interface, L-type geometrical clamp corner is provided with draw-in groove, cross bar is joined end to end by interface, form quadra structure, 4 round bars are each passed through draw-in groove and form support underframe, and at least one pair of traction rope web member is arranged on cross bar and position is relative.
Traction rope web member on described side cross bar is provided with traction rope.
The first scale is equipped with on described cross bar He on round bar.
Described L-type geometrical clamp is provided with the second scale, and after L-type geometrical clamp docks with cross bar, the first scale and the second scale form complete Measurement scales line.
Described round bar lower end is provided with spur.
A kind of sample investigation of the utility model and sampling frame, have following technique effect:
1), by cross bar and L-type geometrical clamp form quadra structure, meanwhile, each bar rib of framework arranges scale, accurately can understand the area of sample prescription thus.In addition because L-type geometrical clamp is fixed by socket with cross bar, be therefore convenient to dismounting and assembling, easy to carry.
2), by arranging the spur of round bar and the round bar lower end that can move up and down relative to quadra, can conveniently be applied to the complex environments such as concavo-convex ground, slope, meanwhile, the adjustment of quadra height is conducive to the mensuration of group's basal cover.
3), by arranging at least one pair of traction rope web member on cross bar, experimentally require sample prescription to be divided into required lattice number, be conducive to plant community cover degree, the Accurate Determining of frequency, many degree; Accurately can gather community biomass in sample prescription and pedotheque simultaneously, reduce experimental error, promote sample investigation quality and work efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Fig. 2 is the structural representation of L-type geometrical clamp of the present utility model.
In figure: cross bar 1, L-type geometrical clamp 2, interface 2-1, draw-in groove 2-2, traction rope web member 3, round bar 4, the first scale 5, second scale 6, spur 7.
Embodiment
As shown in Figure 1 and 2, a kind of sample investigation and sampling frame, comprise cross bar 1, L-type geometrical clamp 2, traction rope web member 3 and round bar 4, described L-type geometrical clamp 2 two ends is equipped with interface 2-1, L-type geometrical clamp 2 corner is provided with draw-in groove 2-2, cross bar 1 is joined end to end by interface 2-1, form detachable quadra structure, because L-type geometrical clamp 2 and cross bar 1 are fixed by socket, not only be convenient to dismounting and assembling, easy to carry, and be connected and fixed relative to original nuts and bolt, add the stability of sample prescription frame and ensure the standard of sample prescription.4 round bars 1 are each passed through draw-in groove 2-2 and form support underframe, and quadra can be made to move up and down.At least one pair of traction rope web member 3 is connected on cross bar 1 and position is relative.
Traction rope web member 3 on described side cross bar 1 is provided with traction rope.Because traction rope web member 3 experimentally can need setting, therefore sample prescription can divide to needs condition by the traction rope of varying number.Improve the accuracy and efficiency of investigation thus, also ensure that the requirement of getting community biomass in sample prescription, sampling in soil seed bank, soil seed pool soil sampling etc. simultaneously, and traction rope shrinks freely, fixing simple possible, handled easily, has saved the field study time.
The first scale 5 is equipped with on described cross bar 1 He on round bar 4.Described L-type geometrical clamp 2 is provided with the second scale 6, and after L-type geometrical clamp 2 docks with cross bar 1, the first scale 5 and the second scale 6 form complete Measurement scales line.Structure thus, makes on the one hand the area that records more accurate, on the other hand, when relate to measure group's basal cover etc. time, round bar independently can be elevated to preset height, thus the measured value needed for obtaining.
Described round bar 4 lower end is provided with spur 7.Structure thus, conveniently carries out good fixing, thus ensures the planarization of sample prescription and the authenticity of area when the sample investigation under the complicated landform such as slope, concavo-convex ground.
Principle of work and step:
1), this device is carried into field, experimentally need connections such as cross bar 1, L-type geometrical clamps 2, and be placed to traction rope web member 3 at the default scale place of relative cross bar, connected by traction rope, sample prescription is divided into required lattice number, the experiment of relevant sample investigation and sampling work can be carried out.
2), according to sample ground condition and requirement of experiment can install round bar additional voluntarily, regulated the height of quadra by round bar after, carry out the measurement similar or extra to (1) again to ensure the planarization of sample prescription and the mensuration to data such as basal covers.
