Technical Field

[0001] This utility model relates to the field of land engineering surveying technology, specifically to a sampling device for land engineering surveying. Background Technology

[0002] During engineering geological surveys, soil samples are usually taken outdoors. Soil samplers are an indispensable tool in land surveys, used to collect samples from the soil for detailed analysis of its properties, composition, and health status.

[0003] A soil sampler for land surveying is disclosed in Chinese Patent Publication No. CN220829369U. This soil sampler for land surveying samples deep soil through a sampling tube, which effectively avoids shallow soil from mixing in during the sampling process of deep soil, thereby improving the accuracy of deep soil testing.

[0004] However, the existing technologies mentioned above are mainly for soil sampling at a single depth. To obtain soil samples at different depths, multiple samplings are usually required, which is not only time-consuming but also labor-intensive. Therefore, there is an urgent need for a sampling device for land engineering surveying. Utility Model Content

[0024] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0025] For the land engineering survey sampling device described in this specific embodiment, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 It includes a base plate 1, a longitudinal adjustment mechanism is fixedly connected to the left side of the base plate 1, and a sampling mechanism is slidably provided at the left end of the longitudinal adjustment mechanism;

[0026] The sampling mechanism includes a motor 11, with a transmission rod 12 fixedly connected to the output end of the motor 11. A drill rod 13 is fixedly connected to the bottom of the transmission rod 12. A first lead screw 14 is rotatably connected inside the drill rod 13. Two first bevel gears 15 are fixedly connected to the surface of the first lead screw 14. Two sampling holes are opened on the left side of the drill rod 13. A sampling cylinder 16 is slidably arranged in each sampling hole. Two sliding grooves are opened inside the drill rod 13. Two second lead screws 17 are rotatably connected in each sliding groove. A second bevel gear 18 is fixedly connected to the right side of each second lead screw 17. A slider 19 is threadedly connected to the surface of each second lead screw 17. A connecting rod is fixedly connected to the top of each slider 19. A mounting block 20 is fixedly connected to the left side of each connecting rod. Each sampling cylinder 16 is threadedly sleeved on the outside of the mounting block 20.

[0027] Through the above technical solution, the base plate 1 serves as the basic platform of the device. A longitudinal adjustment mechanism is fixedly connected to the left side to control the vertical movement of the sampling mechanism. The motor 11 drives the drill rod 13 to rotate via the transmission rod 12, achieving the drilling function. The drill rod 13 integrates a first lead screw 14 and two first bevel gears 15. Two sampling holes are opened on the left side. The sampling cylinder 16 is slidably disposed within the sampling holes and connected to the connecting rod via the mounting block 20. Two second lead screws 17 are installed in each groove inside the drill rod 13, and a slider 19 is threadedly connected to its surface. The slider 19 drives the sampling cylinder 16 to move horizontally via the connecting rod. The first bevel gears 15... Engaging with the second bevel gear 18, the transmission from the rotation of the first lead screw 14 to the movement of the second lead screw 17 is realized. After the drill rod 13 is driven to rotate and drill into the ground by the motor 11, when the first lead screw 14 rotates, the engagement of the first bevel gear 15 and the second bevel gear 18 drives the second lead screw 17 to rotate, thereby causing the slider 19 to move in the groove, realizing the sliding of the sampling tube 16 in the sampling hole. The sampling tubes 16 extend from the sampling hole respectively to realize the stratified sampling of soil at different depths. After the sampling is completed, the first lead screw 14 is rotated in the opposite direction, so that the sampling tube 16 retracts into the sampling hole, completing the sampling action.

[0028] Each slider 19 is slidably disposed in the groove, and each first bevel gear 15 meshes with the second bevel gear 18.

[0029] Through the above technical solution, the slider 19 slides in the groove to ensure the stability of the horizontal movement of the sampling cylinder 16. The meshing of the first bevel gear 15 and the second bevel gear 18 can convert the rotational motion of the first lead screw 14 into the rotation of the second lead screw 17, thereby driving the slider 19 to move horizontally.

[0030] Each sampling hole is connected to a slide groove, and a throttle 21 is fixedly connected to the top of the first lead screw 14.

[0031] Through the above technical solution, the sampling hole is directly connected to the slide groove, so that the connecting rod at the top of the slider 19 can smoothly drive the sampling cylinder 16 to move. The handle 21 is fixed to the top of the first lead screw 14 and is used to manually rotate the first lead screw 14 to control the extension and retraction of the sampling cylinder 16.

[0032] A slot is provided on the left side of the top of the drill rod 13, and a baffle 22 is inserted into the slot.

[0033] With the above technical solution, a slot is opened on the top left side of the drill rod 13, and the baffle 22 is inserted to close the sampling hole, preventing soil from entering the drill rod 13 when not sampling. When sampling in layers, the baffle 22 is lifted so that the sampling tube 16 can be extended.

[0034] The longitudinal adjustment mechanism includes a bracket 23, on which a cylinder 24 is fixedly connected. An adjustment frame 25 is fixedly connected to the output end of the cylinder 24, and a motor 11 is fixedly mounted on the adjustment frame 25.

[0035] Through the above technical solution, the bracket 23 is fixed on the base plate 1 as the basis of the longitudinal adjustment mechanism. The output end of the cylinder 24 is connected to the adjustment frame 25. The vertical position of the adjustment frame is controlled by telescopic control. The adjustment frame 25 is fixed to the motor 11. With the movement of the cylinder 24, the drill rod 13 is raised and lowered to realize the drilling depth adjustment. The sampling mechanism is automatically moved vertically by the cylinder 24.

[0036] Limiting ear plates 26 are fixedly connected to the front and rear ends of the adjusting frame 25, and a limiting rod 27 is slidably inserted inside each limiting ear plate 26. The top of each limiting rod 27 is fixedly connected to the bracket 23.

[0037] Through the above technical solution, the limiting ear plate 26 is fixed at both ends of the adjusting frame 25, and the limiting rod 27 is slidably inserted inside. The top of the limiting rod 27 is fixedly connected to the bracket 23, which restricts the adjusting frame 25 to move only in the vertical direction, prevents the adjusting frame 25 from deviating when driven by the cylinder 24, and ensures the verticality of the drilling.

[0038] Four casters 2 are fixedly connected to the bottom of the base plate 1, a storage box 3 is fixedly connected to the top of the base plate 1, and a pusher 4 is fixedly connected to the right side of the storage box 3.

[0039] Through the above technical solution, four casters 2 are installed at the bottom of the base plate 1 to facilitate the overall movement of the device. The storage box 3 is fixed to the top of the base plate 1 and is used to store the sampling tube 16, tools and other accessories. The push frame 4 is fixed to the right side of the storage box 3 and provides a hand-held push-pull interface, thereby enhancing the portability of the device, integrating storage functions and improving on-site operation efficiency.

[0040] Its working principle is as follows: The device is moved to the work site. Since the bottom of the base plate 1 is equipped with four casters 2, the operator can easily move the entire sampling device to the location where land surveying and sampling are needed by holding the pusher 4 on the right side of the storage box 3. The cylinder 24 in the longitudinal adjustment mechanism starts working, and the output end of the cylinder 24 drives the adjustment frame 25 to move up and down. The limiting ears 26 at both ends of the adjustment frame 25 slide on the limiting rod 27, ensuring the smooth movement of the adjustment frame 25. Because the motor 11 is fixedly installed on the adjustment frame 25, the motor 11 and the sampling mechanism connected to the motor 11 will also move up and down accordingly, thereby achieving… Adjusting the longitudinal position of drill rod 13 allows it to reach a suitable sampling depth. Motor 11 starts, and its output drives the transmission rod 12 to rotate. The transmission rod 12 then drives the bottom drill rod 13 to rotate. The rotating drill rod 13, utilizing its structural features, gradually drills into the soil. During drilling, a baffle in the slot on the top left of drill rod 13 prevents soil and other debris from entering. Once the drill rod 13 reaches the predetermined sampling depth, the operator removes the baffle 22 and rotates the handle 21 on the top of the first lead screw 14, causing it to rotate. Two screws are fixedly connected to the surface of the first lead screw 14. The first bevel gear 15 rotates together with the first lead screw 14. Since the first bevel gear 15 meshes with the second bevel gear 18 on the right side of the second lead screw 17, the rotation of the first bevel gear 15 will drive the second bevel gear 18 to rotate, thereby causing the second lead screw 17 to rotate in the groove. The surface of the second lead screw 17 is threadedly connected to the slider 19. As the second lead screw 17 rotates, the slider 19 slides in the groove. Because the top of the slider 19 is connected to the mounting block 20 through a connecting rod, and the sampling cylinder 16 is threaded onto the outside of the mounting block 20, the sliding of the slider 19 will drive the sampling cylinder 16 through the connecting rod and the mounting block 20. Slide the sampling tube 16 into the sampling hole on the left side of the drill rod 13. The sampling tube 16 extends out of the sampling hole and is inserted into the surrounding soil to collect the soil into the sampling tube 16, thus completing the soil sample collection. After the sampling is completed, turn the handle 21 in the opposite direction to retract the sampling tube 16 into the sampling hole. Then insert the baffle 22 and start the cylinder 24 again to make the adjusting frame 25 drive the drill rod 13 to rise and pull the drill rod 13 out of the soil. The operator can unscrew the sampling tube 16 from the mounting block 20 and store the collected soil sample in the storage box 3 on the top of the base plate. Finally, the operator can move the device to the next work site or leave the site by pushing the pusher.

[0041] It should be noted that, although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
