Abstract
The invention discloses a rice tillering angle measuring instrument. The rice tillering angle measuring instrument comprises a horizontally-moving ruler and a vertical ruler, wherein the horizontally-moving ruler and the vertical ruler are both provided with length scales; the horizontally-moving ruler and the vertical ruler are in perpendicularly-intersected arrangement; the horizontally-moving ruler can move along the vertical ruler; and the horizontally-moving ruler and the vertical ruler are respectively provided with a level meter. According to the rice tillering angle measuring instrument, the level meters on the horizontally-moving ruler and the vertical ruler can ensure that the horizontally-moving ruler is horizontal and the vertical ruler stands vertically; and the horizontally-moving ruler is fixedly arranged at an appropriate height H of the vertical ruler according to the rice tillering height, the width F of rice tillering on the horizontally-moving ruler is recorded, and thus the rice tillering angle can be obtained through automatic calculation in an Excel table through an arctan function formula DEGREES(ATAN(F/H)). Compared with the prior art, the angle measuring instrument allows angle measurement to be converted into length measurement, and has the advantages of being simple and convenient and quick to operate, precise in measured data, not easy to damage and convenient to carry and the like.
Description
Technical field
The present invention relates to a kind of angel measuring instrument, be specifically related to a kind of rice tillering angle measuring instrument, belong to spatial angle measuring field.
Background technology
During current measurement rice tillering angle, normally used is graphometer, need bending even to squat down when measuring rice tillering angle in rice field or greenhouse, slowly graphometer be placed on rice tillering below and as far as possible close, graphometer as far as possible vertical place after read the number of degrees and record.Because rice tillering is many, operate very inconvenient in paddy field; And some graphometers are too little relative to paddy rice, easy reading out of true, causes very large error.And also have operation and carry very inconvenient problem when using larger graphometer to measure, and work efficiency is very low, is difficult to carry out a large amount of experiment material high-acruracy surveys.Therefore, need to provide a kind of brand-new measurement mechanism.
Summary of the invention
The object of this invention is to provide a kind of rice tillering angle measuring instrument, rice tillering angle measuring instrument of the present invention has that measuring accuracy is high, easy to operate, the advantage such as be easy to carry, and uses this angel measuring instrument can measure at the rice field rice tillering angle carrying out lot of materials rapidly and efficiently.
Rice tillering angle measuring instrument provided by the present invention, comprises one and moves horizontally chi and a upright chi, described in move horizontally on chi and described upright chi and be equipped with length scale;
Describedly move horizontally chi and described upright chi is the setting that intersects vertically, and described in move horizontally chi and can move along described upright chi;
Described state to move horizontally on chi and described upright chi be equipped with level meter.
In described rice tillering angle measuring instrument, described in move horizontally chi and described upright chi is fixed connection by fixed knob, by described fixed knob carry out rotation degree of tightness fix described in move horizontally chi and described upright chi.
In described rice tillering angle measuring instrument, described rice tillering angle measuring instrument is also provided with 2 diagonal braces, the bottom of chi and described upright chi joining is moved horizontally described in each described diagonal brace is all arranged at, and two ends are connected with described upright chi with the described chi that moves horizontally respectively, to move horizontally the connection between chi and described upright chi described in strengthening, prevent the movement between them.
In described rice tillering angle measuring instrument, the top of described upright chi is located at by described level meter, to ensure the upright horizontal placement of described upright chi, reduces the error measured.
In described rice tillering angle measuring instrument, described in move horizontally chi and be provided with 2 described level meters, and described in being located at, move horizontally the two ends of chi and described upright chi joining, described in ensureing, move horizontally chi horizontal positioned, reduce the error measured.
In described rice tillering angle measuring instrument, described level meter and the described distance moved horizontally between chi and described upright chi joining are 10 ~ 20cm.
Convenience during in order to take measurement of an angle and accuracy, up mark scale by the length scale of described upright chi, from 0 to 150cm, be preferably accurate to millimeter from distance end points 2cm place, lower end; The described length scale moved horizontally above chi has same scale at two side Fang Jun on the upper side, and scale is counted from the axis place of upright chi, toward both direction with the same scale of tense marker, all from 0 to 40cm, is preferably accurate to millimeter.
Rice tillering angle measuring instrument of the present invention, can ensure to move horizontally chi level and upright chi stands vertically at upright chi and the level meter moved horizontally on chi, according to rice tillering height the suitable height H moving horizontally chi and be fixed on upright chi, record rice tillering arrives the width F moving horizontally chi, and rice tillering angle automatically calculates acquisition by arctan function formula DEGREES (ATAN (F/H)) in Excel shows.The advantages such as compared with prior art, measurement of angle is converted into linear measure longimetry by angel measuring instrument of the present invention, has simple and efficient to handle, measures numerical value accurate, not fragile, easy to carry, thus have very high using value.
Accompanying drawing explanation
Fig. 1 is the structural representation of rice tillering angle measuring instrument of the present invention.
Fig. 2 is the schematic diagram when rice field uses rice tillering angle measuring instrument of the present invention.
In figure, each mark is as follows:
1 moves horizontally chi, 2 upright chis, 3 level meters, 4 length scale, 5 fixed knobs, 6 diagonal braces.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, but the present invention is not limited to following examples.
As shown in Figure 1, be rice tillering angle measuring instrument provided by the invention, it comprises one and moves horizontally chi 1 and a upright chi 2, is equipped with length scale 4 moving horizontally on chi 1 and upright chi 2.Move horizontally chi 1 and upright chi 2 is the setting that intersects vertically, carry out being connected and fixed particular by fixed knob 5, rotation degree of tightness by fixed knob 5 fixes and moves horizontally chi 1 and upright chi 2, and move horizontally chi 1 and can move along upright chi 2, specifically realize by unscrewing and tighten fixed knob 5.
In order to ensure that the vertical-horizontal of upright chi 2 is placed and moves horizontally the horizontal positioned of chi 1, reduce error, on the top of upright chi 2, a level meter 3 is set, 2 level meters 3 are set moving horizontally on chi 1, be located at the two ends moving horizontally chi 1 and upright chi 2 joining respectively, and level of control instrument 3 and the distance moved horizontally between chi 1 and upright chi 2 joining are between 10 ~ 20cm.
