Description

Technical Field

[0001] The utility model relates to the technical field of forestry surveying and mapping, in particular to a surveying and mapping instrument which is easy to install quickly. Background Art

[0002] Forestry refers to the production sector that protects the ecological environment to maintain ecological balance, cultivates and protects forests to obtain timber and other forest products, and utilizes the natural characteristics of forests to play a protective role. Surveying and mapping refers to measuring and drawing. Forestry surveying and mapping is to measure and draw timber in forests and other environments. The staff will place the surveying instrument on the ground for surveying and recording. At present, the general use on the market is to place the support frame on the soil and install the surveying instrument on the support frame. However, it takes a lot of time to install the surveying instrument. Therefore, we have launched a surveying instrument that is easy to install quickly.

[0003] The existing patent (publication number: CN215636177U) discloses a forestry surveying and mapping instrument with good stability, which relates to the field of surveying and mapping technology. The utility model includes a box body, and the bottom bearing of the box body is connected to two vertical drill rods with sharp heads. The two drill rods are inserted into the soil to form support for the entire device. The utility model connects the drill rod with a sharp head to the bearing on the box body, starts the driving mechanism arranged inside the box body, drives the drill rod to rotate, and presses the box body downward by manpower. The drill rod will form a hole in the soil, and the depth of the drill rod drilling into the soil is used to clamp the entire device. The clamping mechanism on the top of the box body clamps the mapping instrument. When taking out the device, the driving mechanism is started and the device is lifted up with force. In summary, the forestry surveying and mapping instrument designed by us has good stability, which replaces the existing method of only placing it on the ground, greatly improves the stability of the device, and the setting of the clamping mechanism makes the device not easy to be knocked over and damaged. The existing technology has the following problems: 1. The existing surveying instrument mainly fixes the middle surveying instrument by driving the suction cup to fix the surveying instrument by twisting the threaded rods on both sides, but the efficiency of rotating the threaded rod to drive the suction cup to move and clamp is low, and the two threaded rods and the suction cup on both sides are independently set. It is difficult to ensure that the surveying instrument is fixed in the middle position of the top of the box when the threaded rod is rotated manually; 2. The existing surveying instrument uses a drill rod to drill into the ground for fixation during installation, but the drill rod itself has no downward force, and the user is required to press the surveying instrument downward while the drill rod is rotating, and the pressing needs to continue until the drill rod is completely drilled into the ground, which requires high physical strength from the user and has high labor intensity.

When the drilling assembly 4 drives the lifting plate 408 to move down to the inner bottom of the shell 1, the lifting plate 408 will contact and press the U-shaped rod 505, and at this time the U-shaped rod 505 will The return spring 506 is squeezed and drives the lifting frame 504 to move downward.

[0030] The use method and advantages of the utility model: When the surveying and mapping instrument which is easy to install quickly is used, the working process is as follows:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, first, the dual-axis motor 405 drives the rotating shaft 403 and the drill rod 406 to rotate at the same time, and two convex strips are fixedly connected to the two sides of the outer surface of the rotating shaft 403, so the rotating shaft 403 can drive the main gear 402 and the rotating cylinder 401 to rotate, and the main gear 402 can drive the sub-gear 404 to rotate. When the sub-gear 404 rotates, it can drive the movable shaft 4014 to rotate through the fixed shaft 4015 at the bottom, and when the movable shaft 4014 rotates, it can drive the upper ring gear 4012 to rotate. The upper ring gear 4012 is squeezed to the lower ring gear 4011 by the squeezing spring 4013 and meshes with it, so the upper ring gear 4012 can drive the threaded rod 4010 to rotate. The purpose of adjusting the height of the lifting plate 408 is thereby achieved. When the drill rod 406 at the bottom output end of the dual-axis motor 405 rotates, the drill rod 406 is an active drill rod 406. The active drill rod 406 can drive the secondary pulley 409 to rotate through the main pulley 407 and the synchronous belt. When the secondary pulley 409 rotates, it drives another driven drill rod 406 to rotate at the same time. The drill rod 406 is connected to the middle part of the lifting plate 408 in rotation. Therefore, the drill rod 406 can rotate while descending with the lifting plate 408. There is no need to apply downward force to the drill rod 406 by manpower to make the drill rod 406 drilled into the ground and fixed, which greatly reduces the labor intensity of the user. In addition, the upper and lower ring gears have an anti-overload function. When the drill rod 40 When encountering a very hard object during the drilling process, the upper ring gear 4012 cannot continue to drive the lower ring gear 4011 to rotate, and the upper ring gear 4012 will compress the extrusion spring 4013. At this time, the two ring gears move relative to each other to prevent the dual-axis motor 405 from overloading and burning. When the surveying instrument body needs to be installed, it is only necessary to place the surveying instrument between the two L-shaped clamps 502 on the top of the shell 1, and then start the drilling assembly 4. When the drilling assembly 4 drives the lifting plate 408 to move down to the bottom of the inner side of the shell 1, the lifting plate 408 will contact the U-shaped rod 505 and press it down. At this time, the U-shaped rod 505 will squeeze the reset spring 506 and drive the lifting frame 504 to move down. The downward movement of the lifting frame 504 will drive the I-shaped slider 501 to move along the slide groove 2 toward the middle of the shell 1 through the top hinged connecting rod 503, thereby clamping and fixing the surveying instrument on the top surface of the shell 1. The greatest advantage of this fixing method is that it is only necessary to place the surveying instrument between the two L-shaped clamps 502. When the drill rod 406 is driven by the lifting plate 408 to drill to a certain depth, the entire device is fixed and automatically drives the two L-shaped clamps 502 to approach each other to clamp and fix the surveying instrument. Since the two L-shaped clamps 502 move synchronously, the surveying instrument body can be automatically fixed in the middle of the shell 1, and there is no need to fine-tune the position of the surveying instrument later, which saves a lot of time.
