Technical Field

[0001] The utility model belongs to the technical field of land surveying and mapping, in particular to a land surveying and mapping device. Background Art

[0002] Land surveying and mapping is the work of measuring and mapping the quantity, distribution and topography of various types of land using surveying and remote sensing technology. It covers topographic surveying, cadastral surveying, land leveling surveying, current land use surveying, and investigation of reserve resources such as barren hills and wastelands.

[0003] In the prior art, when surveying the land, it is necessary to collect soil samples in the surveying area. Currently, most of the soil samples are obtained by inserting a sampling tube deep into the soil. During long-term use and observation, it is found that the traditional soil sampling device has a relatively simple structure. When sampling the soil, the rod often tilts, resulting in inaccurate samples.

[0004] To this end, the utility model provides a land surveying and mapping device. Utility Model Content

When the staff needs to move the soil-taking assembly perpendicular to the plane When the soil is on the ground, the staff will insert the fixing pin 17 into the support frame 1 to limit the connecting ball 11. At this time, the soil taking component will be perpendicular to the ground. The staff rotates the soil taking component, and the spiral pattern 13 will rotate along the threaded groove 14, so that the soil taking component can move downward along the connecting ball 11 and then be inserted into the soil to sample the soil. This step is provided with the support frame 1, the connecting ball 11 and the fixing pin 17, so that the staff can adjust the angle between the soil taking component and the ground according to the sampling requirements, thereby improving the adjustable range of the device when taking soil. When sampling the soil, the soil taking component may tilt its rod body, resulting in inaccurate samples taken. By providing the spiral pattern 13, the staff can more conveniently move the soil taking rod 12 up and down, and the soil taking component can be more easily drilled into the soil, which is convenient for the staff to sample the soil.

[0026] Further, such as Figures 1 to 3 As shown, the soil sampling assembly includes a pair of soil sampling rods 12; the soil sampling rods 12 are arranged in a "C" shape; one end of the soil sampling rod 12 is fixedly connected with a fixing groove 2; the other end of the soil sampling rod 12 is provided with a fixing strip 21; in this step, by arranging the soil sampling rods 12 as a pair, it is convenient for the staff to take out the sample from the inside of the soil sampling rods 12, and by providing the fixing groove 2 and the fixing strip 21, it is convenient for the staff to fix the pair of soil sampling rods 12.

[0027] Further, such as Figures 1 to 3 As shown, a sealing plate 31 is fixedly connected to the top of the fixing groove 2; a handle 3 is fixedly connected to the side wall of the sealing plate 31; by providing the handle 3, the staff can rotate the soil sampling rod 12 more conveniently, thereby improving the work efficiency of the staff when sampling the soil.

[0031] Working principle: During work, the staff places the support frame 1 on the ground. When the staff needs to make the soil extracting assembly perpendicular to the plane, the staff pulls out the fixing pin 17 from the inside of the support frame 1. At this time, the connecting ball 11 will rotate along the support frame 1, so that the soil extracting assembly is perpendicular to the plane. When the staff needs to make the soil extracting assembly perpendicular to the ground, the staff inserts the fixing pin 17 into the inside of the support frame 1 to limit the connecting ball 11. At this time, the soil extracting assembly will be perpendicular to the ground. The staff rotates the soil extracting assembly. At this time, the spiral pattern 13 will rotate along the thread groove 14, so that the soil extracting assembly moves downward along the connecting ball 11 and then is inserted into the soil to sample the soil. By providing an elastic sleeve 6 at the end of the handle 3, the friction can be increased when the user grasps the handle 3.
