Technical field
The present invention relates to a kind of for measuring root system of plant anchor force, analyzing the device of the solid native effect of root system of plant, particularly relate to a kind of portable root system anchoring force detector.
Background technology
At present, in the research for plant solid slope effect, research of the prior art mainly concentrates on research root system of plant being improved to Soil Anti shear resistance, can be measured by equipment such as staight scissors to the shear strength of soil.
But the solid native effect of plant is not only embodied in above-mentioned research.
Summary of the invention
The object of this invention is to provide a kind of can be convenient and swift and measure the portable root system anchoring force detector of the anchor force of root system of plant accurately.
The object of the invention is to be achieved through the following technical solutions:
Portable root system anchoring force detector of the present invention, comprise terrace with edge, round platform, pyramid or cone shape metal support, the top of described metal support is fixed with draw-gear, the towbar of described draw-gear reaches in described metal support, the lower end of described towbar is fixed with geometrical clamp, described towbar is provided with pulling force sensor, and the bottom surface of described metal support is provided with through hole, and the lower of described towbar is rectified described through hole.
As seen from the above technical solution provided by the invention, the portable root system anchoring force detector that the embodiment of the present invention provides, owing to comprising metal support, the top of metal support is fixed with draw-gear, and the towbar of draw-gear reaches in described metal support, and the lower end of towbar is fixed with geometrical clamp, towbar is provided with pulling force sensor, the bottom surface of metal support is provided with through hole, and the lower of towbar is rectified through hole, can be convenient and swift and measure the anchor force of root system of plant accurately.
Accompanying drawing explanation
The structural representation of the portable root system anchoring force detector that Fig. 1 provides for the embodiment of the present invention;
Fig. 2 is the structural representation of pulling force sensor in the embodiment of the present invention;

Embodiment
To be described in further detail the embodiment of the present invention below.
Portable root system anchoring force detector of the present invention, its preferably embodiment be:
Comprise terrace with edge, round platform, pyramid or cone shape metal support, the top of described metal support is fixed with draw-gear, the towbar of described draw-gear reaches in described metal support, the lower end of described towbar is fixed with geometrical clamp, described towbar is provided with pulling force sensor, the bottom surface of described metal support is provided with through hole, and the lower of described towbar is rectified described through hole.
Also comprise receiver, described receiver and described pulling force sensor is wireless or wired connection.
Described receiver is provided with and receives line, display screen, control knob, battery compartment.
Described draw-gear comprises gear, and described gear is connected with runner.
Applicant, by the force analysis to radical operators, finds the effect of the anchoring also having a root system perpendicular to soil plane.By portable root system anchoring force detector of the present invention, can be convenient and swift and measure the anchor force of root system of plant accurately, by pulling force sensor, measurement result directly can be transferred to computer, and can view the change curve of anchor force in root system withdrawal process.And this instrument may be split into two parts, by changing support, can measure the root system of plant anchor force of different size.
The present invention utilizes support and the dynamometric system of small portable, completes the mensuration to root system anchoring power, and is conveyed into computer by induction module, analyzes the dynamic change characterization of anchor force in drawing process.
Specific embodiment:
As shown in Figure 1, comprise metal support 1, geometrical clamp 2(clamp root system of plant top for geometrical clamp), pulling force sensor 3, runner 4, replaceable gear 5 etc.The structure of pulling force sensor 3 as shown in Figure 2.
Also comprise receiver, the contour structures of receiver as shown in Figure 3, comprise receive line 6, display screen 7, control knob 8(comprise switch, menu, unit switching etc.), battery compartment 9 etc.
The application process of specific embodiment is:
Before measurement, the ground of cleaning surrounding plants, makes support to be positioned on ground stably, and makes the line of pulling force sensor and root system of plant perpendicular to soil plane.Use the clip be connected on pulling force sensor to fix upper half region of plant, rotating wheel, stops operating when tautness meter demonstrating reading, and now each assembly of instrument connects closely, and test early-stage preparations are complete.Uniform rotation runner, observes tautness meter reading, when tautness meter reading diminishes or observe when root system of plant is pulled out completely and stop test.By the data importing computer of pulling force sensor, obtain tension variations value, obtain root system of plant anchor force.
To note during application following some:
Note the ground of cleaning vicinity of plants, keep root system of plant direction of pull in drawing process perpendicular to the ground.
In drawing process, keep the velocity of rotation of runner even, too fast or velocity variations affects the accuracy of result compared with senior general.
Holder part is detachable, and can design different supports and pulling force sensor for the forest measuring different size.
The above; be only the present invention's preferably embodiment, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
