Abstract
The utility model discloses a device for measuring a tiller included angle. The device can be used for measuring the tiller included angle of paddy rice and similar paddy rice plants, and comprises at least one supporting rod, a reference rod which is fixedly connected with the supporting rod alternately, and a protractor which is matched with the reference rod for use. When the device is used, the supporting rod is inserted into soil, the reference rod and a tiller form two included angles, the protractor is used for measuring the two included angles formed by the reference rod and the tiller, and the tiller included angle is obtained by subtracting the two included angles from 180 degrees according to a principle that the sum of internal angles of a triangle is equal to 180 degrees. The device can be used for measuring the tiller included angle of the paddy rice and the similar paddy rice plants easily, quickly, intuitively and accurately, and is high in measurement accuracy, small in measurement error, simple in entire structure, and convenient to manufacture and use.
Description
Technical field
The utility model relates to a kind of measurement mechanism, particularly, relates to a kind of angle measurement mechanism of tillering, and can be used for measuring the angle of tillering of paddy rice and class rice plants.
Background technology
At present, in to the research of rice tillering angle, most of measuring methods that adopt have protractor directly to measure method and Method of Cosine, the protractor directly method of measuring is specially directly and measures the angle of tillering with protractor, the method shortcoming is because the angle summit fails to overlap with the protractor initial point, so it is larger to measure error; Method of Cosine is by measuring water intaking rice direction certain-length perpendicular to the ground and the correspondence angle hypotenuse length of tillering with a yardstick, utilize the cosine formula estimation angle of tillering, the method shortcoming angle vertex position that is to tiller is unknown, can only be similar to and think that the position of measuring is the summit, artificial measuring error occurs.Namely two kinds of methods of the prior art all directly adopt separately protractor or ruler as measurement mechanism at present, all have very large error.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect that above-mentioned measurement mechanism measuring accuracy of the prior art is inadequate, measuring error is larger, a kind of angle measurement mechanism of tillering is provided, can be used for measuring the angle of tillering of paddy rice and class rice plants, this device can be convenient and measure exactly the angle of tillering.
To achieve these goals, the utility model adopts following technical scheme:
A kind of angle measurement mechanism of tillering comprises that at least one support bar reaches the reference lever that is fixedly connected with alternately with described support bar, also comprises a protractor that is used with described reference lever.
Further, described support bar is one, and support bar and reference lever can form cruciformity, T-shaped shape, X-type frame shape or inverted L shape frame shape alternately.
Further, be provided with straight line on the described reference lever.
Further, described support bar and reference lever are the flat bar.
Further, the material of described support bar and reference lever is plastics or wooden.
Further, described support bar is that glue is connected, rope connects or screw connects with the connected mode of reference lever.
Further, described protractor all is not connected with support bar or reference lever, or described protractor is connected by connection cord with support bar or reference lever.
Compared with prior art, the utlity model has following beneficial effect:
1, adopt the angle measurement mechanism of tillering of the present utility model, can simply, rapidly, intuitively and accurately measure the angle of tillering of paddy rice and class rice plants, its measuring accuracy is high, measuring error is little, can be further research accurately Data Source is provided.
2, the angle measurement mechanism of tillering of the present utility model, one-piece construction is simple, making, easy to use, and the making material requested is easy to get.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is device construction of the present utility model and schematic diagram;
Fig. 2 is application example of the present utility model.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of angle measurement mechanism of tillering of the present utility model comprises that at least one support bar 2 reaches the reference lever 1 that is fixedly connected with alternately with support bar 2, also comprises a protractor 3 that is used with reference lever 1.
For one-piece construction is more simplified, support bar 2 can only arrange one, and support bar 2 can form cruciformity (as shown in Figure 1) alternately with reference lever 1, and in addition, support bar 2 also can form T-shaped shape, X-type frame shape or inverted L shape frame shape alternately with reference lever 1.
On reference lever 1, straight line can also be set, the reference line when can be used as protractor 3 and using, as this straight line is not set, then can be directly take one side of reference lever 1 as reference line.
Easy to connect and stable for support bar 2 and reference lever 1, support bar 2 all can be selected the flat bar with reference lever 1.
The above-mentioned angle measurement mechanism of tillering of the present utility model, its measuring method is as follows, to measure the rice tillering angle as example, shown in figure 1,2:
Shown in paddy rice model 6, the angle of tillering that we will measure is reached the tiller formation that is positioned at both sides that is extended out by the summit by the summit in soil (rice root).During measurement, fix in the soil with the support bar 2 insertion paddy rice outsides, as far as possible near rice tillering in case reading (such as Fig. 1, shown in 2, can select the support bar 2 vertical rice tillering outsides of inserting near the place, summit), namely form one take reference lever 1 and the triangle of rice tillering as the limit, straight line on reference lever 1(or the reference lever 1) measures angle 4 and 5 with the respectively formation of tillering on both sides, use amount hornwork 3 is measured respectively angle 4 and 5, when protractor 3 reading, straight line on 0 scale mark of protractor 3 and one side of reference lever 1 or the reference lever 1 is overlapping, the straight line on the center of circle of protractor 3 and reference lever 1 or the reference lever 1 and rice tillering points of intersection coincide.Recording respectively reading shown in the protractor 3, is 180 degree principles according to triangle interior angle sum, and 180 degree are deducted two measured angles, can calculate the rice tillering angle.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment the utility model is had been described in detail, for a person skilled in the art, it still can be made amendment to the technical scheme that previous embodiment is put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
