DETAILED DESCRIPTION

[0017] Embodiment 1, as Figure 1-Figure 5 As shown, the land surveying and sampling device for land reclamation and ecological restoration proposed in this embodiment includes a fixing mechanism and a sampling mechanism, and the sampling mechanisms are distributed in multiple groups around the fixing mechanism.

[0018] The sampling mechanism includes a cover 16, a bracket 21 arranged in the cover 16, a rotating drum 20 rotatably arranged on the bracket 21, a sliding column 22 slidably clamped on the rotating drum 20, a screw rod 23 arranged at the bottom of the sliding column 22, a connecting frame 24 arranged at the bottom of the cover 16, a fixing platform 25 arranged on the connecting frame 24 and threadedly connected to the screw rod 23, a fixing ring 35 arranged at the bottom of the screw rod 23, a sampling assembly rotatably arranged at the bottom of the screw rod 23, a gear ring 38 located below the sampling assembly, a plurality of rotating rods 36 connected between the fixing ring 35 and the gear ring 38, and a driving mechanism 1 arranged in the cover 16 and driving the rotating drum 20 to rotate. The rotating rods 36 are selected from harder metal rods, and the number and density of the rotating rods 36 are set to be able to drive the gear ring 38 to effectively rotate into the soil. The sliding column 22 can adopt a polygonal columnar structure, and the rotating drum 20 has a slideway adapted to the sliding column 22. The cover 16 has a through hole for the sliding column 22 to pass through, so as to prevent interference with the movement of the sliding column 22.

[0019] like Figure 1-Figure 4 As shown, the driving mechanism 1 includes a motor 2 17 arranged in the cover body 16, a gear 3 18 connected to the output end of the motor 2 17, and a gear 4 19 meshingly connected to the gear 3 18, and the gear 4 19 is arranged on the rotating drum 20. The output end of the motor 2 17 can rotate forward and reverse, the motor 2 17 drives the gear 3 18 to rotate, the gear 3 18 drives the gear 4 19 to rotate, the gear 4 19 drives the rotating drum 20 forward and reverse, the rotating drum 20 can drive the sliding column 22 to rotate, the sliding column 22 drives the screw rod 23 to rotate, because the screw rod 23 and the fixed platform 25 are threadedly connected, the screw rod 23 will spirally rise and fall, and the sliding column 22 will spirally rise and fall synchronously. When sampling soil, the screw rod 23 is screwed downward, and the toothed ring 38 is driven to be screwed downward through the fixed ring 35 and the rotating rod 36, and the toothed ring 38 is drilled into the soil, and the drilling effect is good. The bottom of the toothed ring 38 has a drilling tooth portion, and the drilling tooth portion is used to drill into the soil, and harder soil can be drilled.

[0020] The sampling assembly includes a rotating plate 26 rotatably arranged at the bottom of the screw rod 23 and a sampling barrel locked with the rotating plate 26. The upper part of the sampling barrel is provided with an air vent. When the soil enters the sampling barrel from below, the air in the sampling barrel is discharged from the air vent on the upper part, which is conducive to the smooth entry of the soil below into the sampling barrel. The sampling barrel includes a cylinder body 1 271 and a cylinder body 2 272, both of which are semi-cylindrical structures and hinged at one end by a hinge 28. The cylinder body 1 271 and the cylinder body 2 272 can be closed into a cylindrical structure. The other ends of the cylinder body 1 271 and the cylinder body 2 272 are locked and connected. The inner diameter of the toothed ring 38 is larger than the outer diameter of the cylinder body 1 271. After the toothed ring 38 drills the soil, a soil column is left inside for the sampling barrel to be inserted. The sampling barrel is squeezed in along the periphery of the soil column, and the soil column is pressed into the inside to achieve soil sampling. Because the rotating plate 26 and the bottom of the screw rod 23 are rotatably connected, there is friction resistance between the sampling tube and the soil. When the gear ring 38 is screwed downward, the sampling tube is basically inserted into the outer periphery of the soil column along the vertical direction. When the sampling tube needs to be moved upward to remove the soil, a plug can be plugged at the vent of the sampling tube to prevent outside air from entering the top of the sampling tube from the vent and prevent soil from falling from the sampling tube. The inner wall of the sampling tube can be frosted to increase the friction between it and the soil and further prevent the soil from falling from the inside of the sampling tube.

[0021] In addition, if Figure 2 As shown, multiple reinforcing rings 37 are sleeved on multiple rotating rods 36 in the vertical direction. The reinforcing rings 37 are located on the outer peripheral side of the sampling tube, so that the rotating rods 36 are not easily deformed and can effectively drive the gear ring 38 to rotate into the soil.

[0022] Scale lines are arranged along the length direction at the butt joint end surfaces when cylinder body 1 271 and cylinder body 272 are closed. When the sampling cylinder is removed and cylinder body 1 271 and cylinder body 272 are opened, the soil layer conditions at various depths can be determined by observing the scale lines.

[0023] This embodiment can insert the sampling tube into the soil by first rotating the drill and then inserting it, which is suitable for sampling harder soil. The toothed ring 38 is rotated into the path, and the soil is loose. The sampling tube can be inserted into the soil column inside the toothed ring 38, and the soil column is accommodated inside. The soil is not easy to fall off, and it is easier to sample. After taking out the soil, the sampling tube is removed from the rotating plate 26, and the soil layer thickness is conveniently measured by opening the sampling tube, which is convenient for subsequent sampling and testing of soil at different depths.

[0024] Embodiment 2, as Figure 1-Figure 5As shown, the land surveying and sampling device for land consolidation and ecological restoration proposed in this embodiment, compared with the first embodiment, in this embodiment, the end of the cylinder body 1 271 away from the hinge 28 is rotatably provided with a limit buckle 1 29, the limit buckle 1 29 has a notch 1 291, and the end of the cylinder body 272 away from the hinge 28 is provided with a convex plate 1 30, and the convex plate 1 30 is threadedly connected with a threaded knob 1 31 that can pass through the notch 1 291 and lock on the limit buckle 1 29. When the cylinder body 1 271 and the cylinder body 2 272 are closed, the limit buckle 1 29 is rotated to the side where the threaded knob 1 31 is located, so that the threaded knob 1 31 is stuck in the inner side of the notch 1 291, and then the threaded knob 1 31 is tightened on the limit buckle 1 29, so that the cylinder body 1 271 and the cylinder body 2 272 are locked, and a complete sampling cylinder is obtained.

[0025] like Figure 4 As shown, two limit buckles 32 are symmetrically arranged on the rotating plate 26, and the limit buckles 32 have a notch 2. The cylinder 1 271 and the cylinder 2 272 are both provided with a convex plate 33, and the convex plate 33 is threadedly connected with a threaded knob 34 that can pass through the notch 2 and be locked on the limit buckle 32. When installing the sampling barrel on the rotating plate 26, the sampling barrel is passed through the gear ring 38 from below, and the top of the sampling barrel is aligned with the bottom of the rotating plate 26. The limit buckle 32 is rotated to make the threaded knob 34 snap into the inner side of the notch 2, and then the threaded knob 34 is tightened on the limit buckle 32, so that the entire sampling barrel is locked on the rotating plate 26 to prepare for soil sampling.

[0026] like Figure 4 As shown, the rotating rod 36 includes a folding rod portion and a vertical rod portion that are integrally connected, and the folding rod portion is located outside the limiting buckle 1 29 and the limiting buckle 2 32, so that the rotating rod 36 will not interfere with the limiting buckle 1 29 and the limiting buckle 2 32 when rotating.

[0027] This embodiment can realize the opening, closing and disassembly of the sampling tube by rotating the threaded knob after the entire device has been sampled and laid down, and the operation is very convenient.

[0028] Embodiment three, as Figure 1-Figure 5As shown, the land surveying and sampling device for land consolidation and ecological restoration proposed in this embodiment, compared with the first embodiment, in this embodiment, the fixing mechanism includes a support 1, a bidirectional screw 6 rotatably arranged on the support 1, a mobile platform 2 92 and a mobile platform 1 91 respectively threadedly connected to the upper and lower sides of the bidirectional screw 6, a plurality of plugs 10 arranged at the bottom of the mobile platform 1 91, a slide rod 11 vertically arranged on the mobile platform 1 91 and slidably connected to the support 1, a top platform 8 arranged at the top of the bidirectional screw 6, a mounting cover 5 arranged on the support 1, a guide rod 7 arranged between the mounting cover 5 and the top platform 8 and slidably connected to the mobile platform 2 92, a driving mechanism 2 arranged in the mounting cover 5 and driving the bidirectional screw 6 to rotate, and a plurality of linkage components that link the cover body 16, the mobile platform 2 92 and the top platform 8. The driving mechanism 2 is located on the inner side of the mounting cover 5, and includes a motor 1 2 arranged on the support 1, a gear 1 3 connected to the output end of the motor 1 2, and a gear 2 4 meshingly connected to the gear 1 3, and the gear 2 4 is arranged on the bidirectional screw 6. Motor 1 2 can drive gear 1 3 to rotate forward and reversely, and gear 1 3 drives bidirectional screw 6 to rotate through gear 2 4. When mobile platform 2 92 rises, multiple sets of sampling mechanisms are deployed, mobile platform 1 91 descends, and plug posts 10 are inserted into the soil to fix the entire device. When mobile platform 2 92 descends, multiple sets of sampling mechanisms are retracted, and mobile platform 1 91 rises and moves out of the soil.

[0029] like Figure 2 As shown, the linkage assembly includes a plate 14 arranged on the side of the top platform 8, a plate 2 15 arranged on the side of the cover body 16, two connecting rods 13 connected in parallel rotation between the plate 14 and the plate 2 15, and a support rod 12 whose two ends are respectively connected in rotation with the moving platform 2 92 and a connecting rod 13. The connecting rod 13, the plate 14 and the plate 2 15 form a parallelogram mechanism. When the moving platform 2 92 is raised or lowered, the support rod 12 is driven to move, the support rod 12 drives the connecting rod 13 to rotate, and the connecting rod 13 drives the cover body 16 to move through the plate 14, so as to realize the expansion or folding of the cover body 16, thereby realizing the expansion or folding of multiple sets of sampling mechanisms.

[0030] This embodiment can realize the expansion or folding of multiple sets of sampling mechanisms by driving the second driving mechanism. When expanded, they can be used for soil sampling; when folded, the occupied space of the entire device can be reduced, which is convenient for storage and transportation.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
