Technical Field
[0001] This utility model relates to the field of forestry, and more specifically, to a forestry field measurement device. Background Technology
[0002] Forestry refers to the production sector that protects the ecological environment and maintains ecological balance, cultivates and protects forests to obtain timber and other forest products, and utilizes the natural characteristics of trees to play a protective role. In the process of forest regeneration, measuring the spacing between trees can guide forestry workers to make reasonable planting plans, thereby ensuring that newly planted trees can obtain sufficient sunlight, water and nutrients, thus promoting their healthy growth.
[0003] A search revealed that Chinese Patent Publication No. CN222144060U discloses "a tree spacing measuring device for forestry field surveys, comprising a strip plate, an infrared ranging mechanism on the left side of the strip plate, and a temporary fixing mechanism on the right side of the strip plate. The infrared ranging mechanism includes a positioning frame, which is fixedly installed on the left side of the strip plate, and a rotating seat is rotatably connected to the inner wall of the positioning frame. This technical solution, through the design of the infrared rangefinder body, fixes it to one of the trees to be measured and aligns it with another tree to be measured, controlling its operation to emit infrared rays, thereby measuring the distance between trees. This avoids the problem of the user having to walk back and forth between the two trees to be measured, improving the efficiency of measurement. At the same time, through the design of the rotatable connection between the positioning frame and the rotating seat, the operator can adjust the infrared rangefinder body to a near-horizontal state, further improving the accuracy of measurement." However, it still has the following drawbacks:
[0004] When adjusting the illumination angle of the infrared rangefinder, the device uses rubber pads to fix the receiving frame and the bent rod. However, with long-term use, the rubber pads will wear down, which will reduce the friction between the bent rod and the positioning frame. Therefore, it needs to be improved.
[0005] Therefore, we have made improvements to this and proposed a forestry field measurement device. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0034] like Figure 1-6 As shown, this embodiment proposes a forestry field measurement device, including a frame 1, a measuring mechanism 2 is provided on the side wall of the frame 1, and a positioning component 3 is provided on the other side wall of the frame 1.
[0035] like Figure 3 and Figure 5As shown, the measuring mechanism 2 includes a vertical plate 201, a positioning plate 202, a fixing rod 203, a spring 204, a disc 205, a positioning groove 206, a mounting part 207, a fixing ring 208, a turntable 209, a sliding hole 210, a fixing tooth 211, a mounting block 212, and an infrared rangefinder 213. The vertical plate 201 is fixedly connected to the side wall of the frame 1. The positioning plate 202 is disposed on one side of the vertical plate 201 and fixedly connected to the side wall of the frame 1. The fixing rod 203 is fixedly connected to the inside of the vertical plate 201, and the spring 204 is sleeved on the fixing rod 203. On the side wall, a disc 205 is slidably connected to the outside of a fixed rod 203. A positioning groove 206 is formed on the side wall of the disc 205. A mounting part 207 is located between the vertical plate 201 and the positioning plate 202 and is bolted to the frame 1. A fixing ring 208 is fixedly connected to the side wall of the mounting part 207. A turntable 209 is rotatably connected to the inside of the fixing ring 208. A sliding hole 210 is formed on the side wall of the turntable 209. A fixing tooth 211 is fixedly connected to the side wall of the turntable 209. A mounting block 212 is fixedly connected to the side wall of the turntable 209. An infrared rangefinder 2... 13 is fixedly connected to the side wall of mounting block 212. The number of vertical plates 201, springs 204, discs 205, mounting parts 207, fixing rings 208, turntables 209, and fixing teeth 211 are all two, and they are arranged opposite each other. Positioning plates 202 are positioned between two adjacent vertical plates 201. Positioning grooves 206 on the two discs 205 are spaced far apart. The number of positioning grooves 206 and fixing teeth 211 are several, and they are distributed circumferentially along the central axis of the discs 205. The fixing teeth 211 are inserted into the positioning grooves 206. Infrared rangefinder 213 Powered by its internal battery, when it is necessary to adjust the illumination angle of the infrared rangefinder 213, the two discs 205 can be brought closer together. At this time, the positioning groove 206 will disengage from the fixing tooth 211, and the turntable 209 will be unrestricted and can rotate inside the fixing ring 208. Then the worker can adjust the illumination angle of the mounting block 212 and the infrared rangefinder 213. After the adjustment is completed, the two discs 205 are released, and the two springs 204 drive the two discs 205 to reset, thereby restricting the position of the turntable 209 again.
[0036] like Figure 4 and Figure 6As shown, the positioning assembly 3 includes a bidirectional lead screw 301, an extension plate 302, an arc-shaped plate 303, a fixing plate 304, a crank handle 305, a slot 306, and a positioning pin 307. The bidirectional lead screw 301 is rotatably connected to the side wall of the frame 1. The extension plate 302 is threaded to the end of the bidirectional lead screw 301. The arc-shaped plate 303 is fixedly connected to one end of the extension plate 302. The fixing plate 304 is fixedly connected to one end of the bidirectional lead screw 301. The crank handle 305 is rotatably connected to the side wall of the fixing plate 304. The slot 306 is formed on the side wall of the frame 1. The positioning pin 307 is slidably connected to the inside of the fixing plate 304. The device is slidably connected to the slot 306. There are two extension plates 302, two arc plates 303, and two fixing plates 304, which are arranged opposite to each other. There are several slots 306 distributed circumferentially along the central axis of the bidirectional lead screw 301. Before measuring the distance, the device is placed on the outside of the tree. Then, the bidirectional lead screw 301 is rotated to bring the two arc plates 303 closer to each other until the two arc plates 303 contact the outer surface of the tree. Then, the positioning pins 307 are inserted into the fixing plate 304 and the corresponding slots 306 in sequence to fix the device on the tree and prevent the protrusions on the ground from affecting the normal use of the infrared rangefinder 213.
[0037] like Figure 5 As shown, an arc-shaped piece 4 is fixedly connected to the side wall of the disc 205 near the positioning groove 206. A circular block 5 is fixedly connected to the other end of the arc-shaped piece 4. One end of the arc-shaped piece 4 passes through the sliding hole 210 and the vertical plate 201 and is slidably connected to the sliding hole 210 and the vertical plate 201. There are six arc-shaped pieces 4, which are arranged in groups of three. The three arc-shaped pieces 4 are distributed circumferentially along the central axis of the fixing rod 203. All three arc-shaped pieces 4 are located outside the fixing rod 203. The outer wall of the arc-shaped piece 4 is tightly fitted to the inner wall of the sliding hole 210. When adjusting the distance between the two discs 205, the discs 205 can be moved more conveniently by pressing the circular block 5 and the arc-shaped piece 4.
[0038] like Figure 1 As shown, a telescopic bellows 6 is sleeved on the outside of the spring 204. The two ends of the telescopic bellows 6 are fixedly connected to the side wall of the disc 205 and the side wall of the positioning plate 202, respectively. There are two telescopic bellows 6, which are located on the outside of the two springs 204. When in use, the telescopic bellows 6 can protect the spring 204, prevent foreign objects from entering the spring 204, and improve the service life of the spring 204.
[0039] like Figure 1 As shown, several anti-slip protrusions 7 are fixedly connected to the side wall of the arc plate 303. By setting the anti-slip protrusions 7, the arc plate 303 can be prevented from slipping on the outer surface of the tree.
[0040] like Figure 1As shown, a level 8 is fixedly connected to the side wall of the mounting block 212. The level 8 is located on one side of the infrared rangefinder 213. By setting the level 8, it is easier to determine whether the infrared rangefinder 213 is horizontal, thereby improving the accuracy of the distance measurement.
[0041] like Figure 4 As shown, a guide rod 9 is fixedly connected to the side wall of the frame 1. One end of the guide rod 9 passes through the extension plate 302 and is slidably connected to the extension plate 302. When the device is fixed on the outer surface of the tree, the guide rod 9 can prevent the extension plate 302 from rotating on the bidirectional lead screw 301, thereby improving the stability of the device.
[0042] Specifically, when using this forestry field measurement device: the infrared rangefinder 213 is existing technology and will not be elaborated on here. During use, place the device on the outside of the tree, then rotate the double-acting screw 301 to bring the two arc-shaped plates 303 closer together until the two arc-shaped plates 303 and the anti-slip protrusion 7 contact the outer surface of the tree. Then, insert the positioning pins 307 into the fixing plate 304 and the corresponding slots 306 in sequence, thereby fixing the device to the tree. If it is necessary to adjust the illumination angle of the infrared rangefinder 213, the circular block 5 and the arc-shaped plate 4 can be manually pressed to make the two discs 2... When the 05 trees approach each other, the positioning groove 206 will disengage from the fixing tooth 211. At this time, the turntable 209 will be unrestricted and can rotate inside the fixing ring 208. Then, the worker can adjust the illumination angle of the mounting block 212 and the infrared rangefinder 213. With the assistance of the level 8, the infrared rangefinder 213 can be easily leveled. After the adjustment is completed, the two round blocks 5 are released, so that the two springs 204 drive the two round discs 205 to reset, thereby restricting the position of the turntable 209 again. Then, the distance between the trees can be measured by the infrared rangefinder 213.
[0043] All technical features in this embodiment can be freely combined according to actual needs.
[0044] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
