Description
Technical Field
The utility model relates to a novel trees angle measuring apparatu that is lopped is applicable to the angle data of measuring contained angle between arbor trunk branch and the trunk, is applied to in the middle of the study of trees growth law. And the method is also suitable for measuring the angle of similar objects.
Background
The branch-planting angle refers to an angle formed between a trunk and branches when branches of arbor species are planted on the trunk, usually the degree of the branch-planting angle is less than 90 degrees, and the phenomenon that the degree of the branch-planting angle is more than 90 degrees appears when the growth period of individual tree species is prolonged.
The branch angle is very important for researching the growth rule of trees and constructing a tree growth model and a forest stand growth model, so that the accurate and rapid measurement of the branch angle of the trees is very important for forestry researchers.
The traditional method for measuring the angle of the branches of the trees adopts a flat protractor for students to measure, namely, the plane of the protractor is placed on a trunk, the circle center of the protractor is close to the position where the branches are planted, and the angle formed by the side branches is measured through the protractor. This method has some problems: 1, the measurement position is difficult to master, and the measurement angle is difficult to find because the branch is thick after growing for many years and the branch can bend after growing for many years; 2, the measurement precision can not be guaranteed, and due to the fact that the protractor for students is semicircular and the shape of the branches, an observer cannot accurately read the degree of the pruning angle.
Therefore, if the angle of the tree landing angle is required to be measured quickly and accurately, the measuring instrument is required to have the advantages of being convenient to carry, easy to operate, high in measuring precision and the like.
SUMMERY OF THE UTILITY MODEL
1. Problems to be solved
Improve measurement of efficiency and measurement accuracy and be the utility model discloses the main problem that needs the solution still needs to have easily to carry moreover, advantages such as good operation.
2. Technical scheme
The device principle is that the device which is convenient to put into the inner part of the tree pruning angle is utilized to determine the angle of the pruning angle, and the degree of the pruning angle is calculated by utilizing the principle that a digital display angle ruler automatically measures the angle of any included angle.
The utility model relates to a novel trees angle measuring instrument that is being attached to a branch utilizes the principle of the arbitrary contained angle of automatic measurement of digital display bevel protractor, changes the structure of the digital display bevel protractor commonly used on the market, makes inside its angle of being attached to a branch that can place the trees under survey, measures the angle at angle of being attached to a branch to reach the purpose of acquireing data.
The invention discloses a novel tree landing angle measuring instrument, which consists of a measuring support rod and a digital display angle ruler. The total number of the measuring supporting rods is 3, the measuring supporting rods are all fixed on one side of the digital display angle ruler and are perpendicular to the ruler body of the digital display angle ruler, and when the digital display angle ruler returns to zero, the 3 measuring supporting rods are collinear. Wherein 2 measuring struts are fixed on the body of the digital display angle ruler, and 1 measuring strut is fixed at the joint of the body of the digital display angle ruler and connected with the rotating shaft of the digital display angle ruler. The inner side of the ruler body at one side of the digital display angle ruler is provided with an opening, and when the digital display angle ruler returns to zero, the measuring support rod on the ruler body at the other side can be placed in the opening.
Preferably, the measuring support rod is made of high-strength alloy materials, is light, hard and small in elasticity, and is cylindrical, the diameter of the measuring support rod is about 3-5mm, and the length of the measuring support rod is 100 mm. The diameter of 3-5mm can ensure that the measuring support rod can be well placed at the bottom of the branch angle. The length of 100mm can ensure that when the trunk is too thick or too thin, the placement of the instrument cannot be influenced, because the thicker trunk surface can form a wider approximate plane, and branches live on the trunk, when the branches are thinner, the larger plane formed by the trunk can influence the placement of the instrument (although the measuring support rod is thinner, the digital display angle ruler has a certain width, how to measure the short support rod, the ruler body of the digital display angle ruler can be attached to the trunk, and the wider ruler body of the digital display angle ruler can influence the accuracy of angle measurement), so that the measurement accuracy is influenced; when the trunk is too thin, the spacing between the branches can diminish, and if the measuring support rod is too long, the adjacent branches can influence the measuring work of the instrument. All the vertical fixation of 3 survey branch is in one side of digital display bevel protractor, and 1 vertical fixation in the survey branch is in the blade junction of digital display bevel protractor, with the pivot connection of digital display bevel protractor, and 2 survey branch vertical fixation are in blade one side of digital display bevel protractor in addition, and when digital display bevel protractor zero return, 3 survey branch collineations. The distance between the position of the measuring support rod on the body of the digital display angle ruler and the measuring support rod fixed at the joint of the body of the digital display angle ruler is about 5-8cm, and the measured data at the distance can accurately express the real angle of the branch angle (the trunk and the branches are not flat surfaces, and the accuracy of the data is influenced by overlarge length). When data measurement is carried out, the measuring support rods fixed at the connecting parts of the ruler bodies of the digital display angle ruler are placed at the bottom of a branch landing angle of a trunk (namely, the positions of the joints of the branches and the trunk), one of the other 2 measuring support rods is attached to the trunk, the other measuring support rod is attached to a branch to be measured, and the angle formed by the 3 measuring support rods is the angle of the branch landing angle.
Preferably, the digital display angle ruler consists of a digital display angle sensor and a digital display angle ruler body, wherein the ruler body is made of alloy materials, and is light in weight, hard, small in contractibility and good in smoothness. An opening is reserved on one side of the body of the digital display angle ruler close to the inner side, when the digital display angle ruler returns to zero (namely, the two bodies are combined, and the angle of the digital display angle ruler returns to zero), the measuring support rod of the other body can be placed in the opening to prevent the angle ruler from being incapable of returning to zero. The digital display angle sensor is positioned at the joint of the body of the digital display angle ruler, the angle data are transmitted to the digital angle sensor through the rotation of the body, and the data displayed by the digital display angle ruler are displayed, namely the angle data of the branch angle are measured.
