[0029] See also Figure 1 - Fig.10 A convenient-to-operate land surveying and calibration device comprises a marking mechanism 1, a cleaning mechanism 2 is arranged at the lower end of the marking mechanism 1, the marking mechanism 1 comprises a supporting tube 11, the outer side of the supporting tube 11 is connected with a supporting frame 3 through a damping rotating shaft, a first annular groove 12 is provided on the inner side of the supporting tube 11, a rotating ring 13 is rotatably connected to the inner side of the first annular groove 12, a rotating disk 14 is fixedly connected to the inner side of the rotating ring 13, a plurality of groups of sliding grooves 15 are provided on the upper end of the rotating disk 14, a rotating groove 16 is provided on the inner side of the rotating disk 14, a plurality of groups of moving components 17 are movably connected to the upper end of the rotating disk 14, a second annular groove 18 is provided on the inner side of the supporting tube 11, a rotating plate 19 is rotatably connected to the inner side of the second annular groove 18, and a cross groove 110 is provided on the inner side of the rotating plate 19.

[0030] In this embodiment, the moving component 17 includes a first internally threaded tube 171, which is slidably connected to the inner side of the cross groove 110, and a moving rod 172 is fixedly connected to the outer side of the first internally threaded tube 171. A spring 173 is commonly provided between the moving rod 172 and the cross groove 110. The lower end of the moving rod 172 passes through the cross groove 110 and is fixedly connected to a sliding ball 174. The lower end of the sliding ball 174 is fixedly connected to a sliding block 175, and the sliding block 175 is slidably connected to the inner side of the sliding groove 15.

[0031] Specifically, under the output of the second motor 29, the second gear column 212 is driven to rotate through the first gear column 210, and the turntable 14 is rotated under the engagement of the gear 213 and the inner gear ring 214. When the turntable 14 rotates, the connection between the slider 175 and the slide groove 15 allows the moving rod 172 and the first internally threaded tube 171 to move with the turntable 14, and the first internally threaded tube 171 is connected to the inner side of the cross groove 110, so that when the first internally threaded tube 171 moves with the turntable 14, the rotating plate 19 is driven to rotate at the same time.

[0032] In this embodiment, the inner side of the first internal threaded tube 171 is movably connected with a mark rod 112, the lower end of the mark rod 112 is fixedly connected with a cone block 111, the outer side of the mark rod 112 is fixedly connected with an external threaded tube 113, the external threaded tube 113 is threadedly connected to the first internal threaded tube 171, the upper end of the mark rod 112 is fixedly connected with a connecting column 114, the outer side of the connecting column 114 is fixedly connected with a stopper 115, a third annular groove 116 is provided on the inner side of the support tube 11, the inner side of the third annular groove 116 is fixedly connected with a first baffle 117, one end of the first baffle 117 extends to the surface of the turntable 14, one end of the first baffle 117 is fixedly connected with an arc plate 118, the outer side of the arc plate 118 is fixedly connected with a second baffle 119, and one end of the second baffle 119 is fixedly connected to the inner side of the third annular groove 116.

[0033] Specifically, as the turntable 14 rotates, the sliding ball 174 will come to the side of the first baffle 117, and the first baffle 117 will block the sliding ball 174 from continuing to move with the turntable 14. Through the inclined setting of the first baffle 117 and the condition that the slider 175 is slidingly connected with the slide groove 15, the sliding ball 174 will slide with the mark rod 112 in the direction of the second internal threaded tube 23. Then, as the turntable 14 continues to rotate, the sliding ball 174 will slide to the side of the arc plate 118, so that the first internal threaded tube 171 and the second internal threaded tube 23 are on the same vertical line, thereby moving the mark rod 112 to the top of the second internal threaded tube 23, completing the automatic filling of the mark rod 112.

[0034] In this embodiment, the upper end of the support tube 11 is fixedly connected to an extension plate 120, and a camera 121 is installed on the upper end of the extension plate 120. A connecting tube 122 is installed on the lower end of the camera 121. A multi-stage electric push rod 123 is provided on the inner side of the connecting tube 122. The output end of the multi-stage electric push rod 123 is fixedly connected to a first motor 124, and the output end of the first motor 124 is fixedly connected to a rotating block 125, and the lower end of the rotating block 125 is fixedly connected to a connecting rod 126.

[0035] Specifically, the multi-stage electric push rod 123 and the first motor 124 are started at the same time, so that the rotating block 125 and the connecting rod 126 move downward and rotate at the same time. When the rotating block 125 moves down to contact the connecting column 114, the rotation of the connecting rod 126 pushes the block 115 to move, thereby causing the benchmark 112 to rotate. With the continuous output of the multi-stage electric push rod 123 and the first motor 124, the benchmark 112 and the external threaded tube 113 rotate and move downward, so that the external threaded tube 113 passes smoothly through the first internal threaded tube 171 and the second internal threaded tube 23, and the benchmark 112 and the cone block 111 are rotated and inserted into the soil. The benchmark 112 can be marked and the operation is convenient.

[0036] In this embodiment, the impurity removing mechanism 2 includes a connecting plate 1 21 and a connecting plate 2 22. The upper ends of the connecting plates 1 21 and 22 are fixedly connected to the supporting tube 11. The inner side of the connecting plate 1 21 is fixedly connected to a second internally threaded tube 23. The upper end of the second internally threaded tube 23 extends to the inner side of the rotating groove 16. The lower end of the connecting plate 1 21 is provided with two groups of multi-stage electric push rods 24. The output ends of the two groups of multi-stage electric push rods 24 are fixedly connected to a connecting plate 3 25. The inner side of the connecting plate 3 25 is rotatably connected to a rotating drum 26. The second internally threaded tube 23 is rotatably connected to the rotating drum 26. The outer side of the rotating drum 26 is fixedly connected to an outer gear ring 27. A connecting plate 4 28 is fixedly connected to one side of the connecting plate 3 25. A second motor 29 is installed on the inner side of the connecting plate 4 28. The output end of the second motor 29 is fixedly connected to a first gear column 210, and the first gear column 210 is meshed with the outer gear ring 27.

[0037] Specifically, when there is grass in the area to be calibrated, the second motor 29 is started to rotate the first tooth column 210. When the first tooth column 210 rotates, it engages the outer tooth ring 27 to rotate the drum 26, thereby rotating the blade 215 to cut the grass. When the grass is deep, it is only necessary to start the multi-stage electric push rod 24 to push the connecting plate 3 25 downward, so that the blade 215 breaks and cleans the grass from top to bottom.

[0038] In this embodiment, the inner side of the connecting plate 22 is rotatably connected to a rotating rod 211, the lower end of the rotating rod 211 is fixedly connected to a second tooth column 212, the upper end of the rotating rod 211 is fixedly connected to a gear 213, the second tooth column 212 and the gear 213 are meshed with the first tooth column 210, the outer side of the gear 213 is meshed with an inner gear ring 214, the upper end of the inner gear ring 214 is fixedly connected to the turntable 14, and the outer side of the rotating drum 26 is fixedly connected to multiple groups of blades 215, the blades 215 are located below the connecting plate 3 25, and the lower end of the blades 215 is provided with a brush 216.

[0039] Specifically, when the connecting plate 25 drives the blade 215 to move down close to the ground, the brush 216 cleans the ground surface under the rotation of the drum 26, effectively preventing the gravel on the ground from affecting the insertion of the benchmark 112, making the area to be calibrated clean, thereby ensuring the calibration effect.

[0040] When in use, the support frame 3 is spread out and placed on the land to be surveyed. After surveying, when calibration work is required, multiple groups of benchmarks 112 are inserted into the first internally threaded cylinder 171 in sequence, and the externally threaded cylinder 113 is located at the upper end of the first internally threaded cylinder 171 without rotating. When there is grass in the area to be calibrated, the second motor 29 is started to rotate the first tooth column 210. When the first tooth column 210 rotates, it engages the external tooth ring 27 to rotate the rotating drum 26, so that the blade 215 rotates to cut the grass. When the grass is deep, it is only necessary to start the multi-stage electric push rod 24 to push the connecting plate 3 25 downward, so that the blade 215 breaks and cleans the grass from top to bottom, and then the second motor 29 stops outputting. In addition, When the first tooth column 210 meshes with the outer tooth ring 27 and rotates, it will mesh with the second tooth column 212 to rotate it. When the second tooth column 212 rotates, the gear 213 is rotated at the same time under the connection of the rotating rod 211, and the gear 213 is meshed with the inner tooth ring 214, so that the rotating disk 14 is also rotated at the same time. When the rotating disk 14 rotates, it is connected through the slider 175 to drive the sliding ball 174 to move with the rotating disk 14, and under the connection between the moving rod 172 and the first internal threaded tube 171, the marking rod 112 is driven to move at the same time. As the rotating disk 14 rotates, the sliding ball 174 will come to one side of the first baffle 117, but as the rotating disk 14 continues to rotate, the first baffle 117 will block the sliding ball 174 from continuing to move with the rotating disk 14. Through the inclined setting of the first baffle 117, and under the condition that the slider 175 is slidably connected with the slide groove 15, the sliding ball 174 will slide with the benchmark 112 in the direction of the second internally threaded cylinder 23, and then continue to rotate with the rotation of the turntable 14, the sliding ball 174 will slide to one side of the arc plate 118, so that the first internally threaded cylinder 171 and the second internally threaded cylinder 23 are on the same vertical line, and then the second motor 29 will stop outputting, so that the benchmark 112 and the cone block 111 are kept above the second internally threaded cylinder 23, and then the multi-stage electric push rod 123 and the first motor 124 are started at the same time, so that the rotating block 125 and the connecting rod 126 move downward and rotate at the same time. When the rotating block 125 moves down to contact with the connecting column 114, as the connecting rod 126 is connected, the rotating block 125 is connected to the connecting column 114. The rotation of rod 126 will push block 115 to move, so that the marker rod 112 rotates. With the continuous output of multi-stage electric push rod 123 and first motor 124, marker rod 112 and external threaded barrel 113 rotate and move downward, so that external threaded barrel 113 smoothly passes through first internal threaded barrel 171 and second internal threaded barrel 23, and marker rod 112 and cone block 111 rotate and insert into soil, completing marking work. If marking work at the next place is required, multi-stage electric push rod 24 and multi-stage electric push rod 1 123 need to be retracted at this time, and then the device is moved to the next place to be marked, and the above operation can be repeated. In the process of rotating disk 14 to move the next group of marker rods 112 in the direction of second internal threaded barrel 23,The upper set of sliding balls 174 and the first internally threaded barrel 171 continue to move with the slider 175 following the turntable 14. Then, when the sliding balls 174 move to the position of the second baffle 119, the slider 175 slowly slides inside the slide groove 15 and gradually moves away from the second internally threaded barrel 23 through the pulling force of the spring 173 and the blocking limit of the second baffle 119. At this time, the next set of first internally threaded barrels 171 come to the top of the second internally threaded barrel 23 with the marking rod 112, ready to continue the marking process.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
