Description

Tree breast diameter measuring device

Technical Field

The utility model relates to a forest measures technical field, especially relates to a tree diameter at breast height measuring device.

Background

The diameter at breast height refers to the diameter of the main trunk of the arbor at the position higher than the breast surface, and is one of the most basic factors for the measurement of the standing tree. The chest heights of different arbors are different, the specifications of different countries on the chest diameters are also different, and the chest height positions of China and most countries are determined to be 1.3m higher than the ground.

The existing method for measuring the breast diameter of the tree generally adopts a tape measure or a ruler to measure the position of the tree, which is 1.3m away from the ground, and after marks are made, the breast diameter of the tree is measured in the circumferential direction at the marked position by using the tape measure or a vernier caliper. According to the measuring method, a worker needs to bend down to measure the vertical height of the tree and then measure the breast diameter in the circumferential direction, and if the number of the trees to be measured is large, time and labor are wasted.

In view of the above, it is necessary to provide a tree diameter at breast height measuring device to solve the above problems.

In the figure: the ruler comprises a ruler 1, a positioner 2, a tape 3, a ruler channel 4, a first screw hole 5, a first bolt 6, a second screw hole 7, a threaded rod 8, a butt plate 9, a fixing plate 10 and a grab handle 11.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, fig. 1 is a schematic side view of a tree breast-height diameter measuring device provided by the present invention; FIG. 2 is a schematic top view of the fixture of FIG. 1; fig. 3 is a front structural view of the straightedge of fig. 1.

This trees chest diameter measuring device includes: a straightedge 1, a locator 2 and a tape 3.

The middle part of the locator 2 is vertically provided with a ruler channel 4 which runs through the upper surface and the lower surface of the locator. A first screw hole 5 is formed in the rear side of the positioner 2, the first screw hole 5 is vertically communicated with the ruler channel 4, and a first bolt 6 is in threaded connection with the first screw hole 5. The ruler 1 is inserted into the ruler channel 4 and fixed through the first bolt 6. In this embodiment, the first screw holes 5 and the first bolts 6 are provided in two, and the two first screw holes 5 are correspondingly provided on the rear side of the positioner up and down. As the chest height position of China and most countries is determined to be 1.3m higher than the ground, the length of the ruler 1 is not less than 1.4m, and the scale surface of the ruler 1 faces the rear side of the positioner 2. The top end of the ruler 1 is fixedly provided with the grab handle 11, and the bottom end of the ruler 1 can be arranged to be of a square sheet structure perpendicular to the ruler 1, so that the ruler is convenient to place.

The middle part of the front side of the locator 2 is provided with a second screw hole 7 which is transversely arranged, one end of a threaded rod 8 is inserted into the second screw hole 7 and is in threaded connection with the second screw hole 7, and the other end of the threaded rod is fixedly connected with a resisting plate 9. The butt plate 9 is a circular structure, and the top of the butt plate is lower than the bottom of the fixing plate 10.

The front side of the locator 2 is connected with a fixing plate 10, the tape 3 is fixed on the fixing plate 10, the opening end of the tape 3 faces to the side far away from the locator 2, and the upper end face of the graduated ruler of the tape 3 is flush with the upper surface of the locator 2.

This trees chest footpath measuring device, when measuring trees height, the staff can directly touch to the ground the ruler bottom, and it can to get the height through the ruler degree. When the breast height of a tree needs to be measured, if the breast height of 1.3m needs to be measured, the grab handle needs to be grasped firstly, the ruler is inserted into the ruler channel, the scale of 1.3m is just exposed out of the top port of the ruler channel, namely the upper surface of the positioner, the position of the tape measure is 1.3m, and then the ruler is fixed by screwing the first bolt; and then, rotating the threaded rod to enable the abutting plate to extend forwards and abut against the trunk, then pulling out the ruler of the tape measure, and reading after surrounding the trunk for a circle, wherein the obtained numerical value is the numerical value of the breast diameter. The whole process does not need to bend down the lower ruler, only needs to put down the ruler, then leans against the abutting plate in front, and finally surrounds the reading, so that the method is very convenient, and if a plurality of trees need to be measured, the position of the ruler does not need to be changed, and the measurement is faster.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
