Forest size measuring instrument

Abstract

The invention discloses a forest tree size measuring instrument which comprises a handheld frame, a handle is arranged at the top end of the handheld frame, the bottom end of the handheld frame is connected with a measuring device, the measuring device comprises an operating panel, a connecting rod, a left clamping arm and a right clamping arm, the left clamping arm and the right clamping arm aresymmetrically arranged, and the front ends of the left clamping arm and the right clamping arm obliquely extend outwards to form a splayed shape; arc-shaped clamping grooves are formed in the inner side of the left clamping arm and the inner side of the right clamping arm. The left clamping arm is provided with a meter counter I, a measuring line I, a winding shaft and a front-back clamping head sliding front and back, and the right clamping arm is provided with a guide rod and a left-right clamping head sliding left and right. A controller is arranged on the handheld frame, a display screen,a clock chip, a memory card and a keyboard are arranged on the controller, the display screen is arranged on the upper surface of the controller, and data of the meter counter I and the meter counterII are displayed on the display screen. The invention has the characteristics of high measurement efficiency, rapid data recording, high measurement precision and convenience in use.

Description

technical field

[0001] The invention relates to a tree size measuring instrument. Background technique

[0002] In the process of measuring the size of landscaping trees, gardeners generally use a tape measure to measure around the greening trees. The following problems exist in the process of measurement: 1. The trees are thick and thin, and the shape of the trees is often irregularly circular. Due to the small deformation of the tape measure, it is difficult to stick to the trunk for the concave-convex position, which affects the accuracy of the measurement. . 2. General measurement requires the cooperation of two people, one to measure and the other to record the data. The measurement efficiency is not high, and the recording is not standardized at the same time, which makes it difficult to enter the later information. 3. Calipers are generally used to measure the diameter of green trees. When measuring the circumference and diameter, it is necessary to switch measureme...
