Problems solved by technology

Internationally, it is generally believed that the diameter of the trunk at a height of 4.5 feet (about 1.37m) is the closest to the true diameter of the tree. When measuring the diameter of a single standing tree in China, most of them rely on the experience of the operator to estimate the position of 1.3m, and measure it with a tape measure The circumference of the tree, and then calculate the diameter value of the tree, or directly read the diameter value of the tree by using a diameter measuring gage that is equal to the relationship between the circumference equal to π times the diameter and marking the scale on the ruler like a tape measure. The operation process requires manual reading Acquiring and recording measurement data and processing the data, the measurement speed is slow, the labor intensity is high, and it is not convenient for the statistics and management of the data

Embodiment 1

[0023] see Figure 1-6 As shown, the plant diameter measuring device includes a fixed plate 1, a scale 8 and a slide bar 3 are vertically inserted into the two ends of the fixed plate 1, and the other end of the scale 8 and the slide bar 3 are vertically inserted into the two ends of the movable plate 7 Inside, a quadrilateral measurement area is formed, and the two ends of the fixed plate 1 and the movable plate 7 are respectively provided with elastic bolts 2 . A scale and a slide bar are vertically inserted into the two ends of the fixed plate, and the other end of the scale and the slide bar are vertically inserted into the inside of the two ends of the moving plate to form a quadrilateral measurement area for measuring the diameter of the plant. The set scale , can show the diameter of the plant more intuitively. The two ends of the fixed plate and the movable plate are respectively equipped with elastic bolts. By adjusting the tightness, the movable plate can move up and...

Embodiment 2

[0032] The working principle of the plant diameter measuring device of the present invention is as follows: on the moving plate 7, by adjusting the elastic bolts 2 at both ends, the moving plate 7 is rotated out around one end, and the belt measuring plant diameter at breast height is placed in the quadrilateral measurement area for measurement, and the lower end surface of the moving plate 7 A cleaning knife 19 is installed to clean up the miscellaneous branches at the breast diameter of the plant to be measured, fix one side of the plant through the fixing device 20, then rotate the moving plate 7 back, and slide the moving plate 7 on the upper end of the scale 8 , so that the mobile plate 7 fits the other side of the plant, and tighten the elastic bolts 2 at both ends. At this time, the display panel 9 displays the plant diameter at breast height, and the data transmitter 91 provided is used to measure the diameter of the plant measured by the scale 8. The DBH size is transm...

Abstract

The present invention discloses a plant breast diameter measuring device. The device comprises a fixing plate. A scale and a sliding rod are vertically inserted into the inner part of both ends of thefixing plate, and the other ends of the scale and the sliding rod are vertically inserted into the inner sides of both ends of a moving plate to form a quadrilateral measuring area. The fixing plateand the moving plate are respectively provided with elastic bolts at both ends. According to the technical scheme of the present invention, the scale and the sliding rod are vertically inserted into the inner part of both ends of the fixing plate, the other ends of the scale and the sliding rod are vertically inserted into the inner sides of both ends of the moving plate to form a quadrilateral measuring area for measuring the plant breast diameter, and by using the scale, the plant breast diameter can be more intuitively displayed; and the fixing plate and the moving plate are respectively provided with elastic bolts at both ends, and the moving plate can be moved up and down by adjusting the elasticity, so that the measuring distance can be adjusted, and the measurement is more convenient.

Description

technical field [0001] The invention belongs to the field of environmental technology, and in particular relates to a plant diameter measuring device. Background technique [0002] In forest resources investigation, the measurement of tree diameter is a very important content. Internationally, it is generally believed that the diameter of the trunk at a height of 4.5 feet (about 1.37m) is closest to the true diameter of the tree. When measuring the diameter of a single standing tree in China, most of them rely on the operator's experience to estimate the position of 1.3m, and measure it with a tape measure The circumference of the tree, and then calculate the diameter value of the tree, or directly read the diameter value of the tree by using a diameter measuring gage that is equal to the relationship between the circumference equal to π times the diameter and marking the scale on the ruler like a tape measure. The operation process requires manual reading Acquiring, record...
