Description

Technical Field

[0001] This utility model relates to the field of saline-alkali land sampling technology, specifically a convenient and fixed saline-alkali land sampling device. Background Technology

[0002] The improvement and utilization of saline-alkali soils require precise soil sampling and analysis to detect key indicators such as salt content, pH value, and nutrient distribution. Traditional manual sampling methods are inefficient and cannot guarantee the consistency of sampling depth and the accuracy of stratification, affecting the reliability of test results.

[0003] The existing patent (authorization announcement number: CN222419544U) discloses a soil sampling device for saline-alkali land improvement. The key technical points of the solution are: the soil sampling component can realize the purpose of convenient automatic stratified sampling of saline-alkali land soil, and the soil sample storage component can realize the purpose of convenient and timely storage of soil samples, thereby improving the sampling efficiency of saline-alkali land soil.

[0004] However, the above-mentioned technical solutions still have certain defects. During the sampling process, because the surface layer of saline-alkali soil is soft or compacted, ordinary samplers are prone to tilting when inserted, resulting in the sampling position shifting. The device uses a spiral drill for sampling, but it lacks a fixed structure and is prone to shaking in soft soil. Therefore, a saline-alkali soil sampling device that is easy to fix is ​​proposed. Utility Model Content

[0005] The purpose of this invention is to provide a convenient and fixed sampling device for saline-alkali land to solve the problems in the background art.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] In one embodiment, such as Figures 1-5 As shown, a conveniently fixed saline-alkali land sampling device includes a fixing box 1, handles 2 fixedly installed on both sides of the fixing box 1, a fixing component 3 provided on the inner wall of the fixing box 1, and a sampling component 4 provided at the bottom of the fixing box 1.

[0033] In this embodiment, the fixed box 1 serves as the main frame, providing a stable support structure so that the entire device is not easily shaken during the sampling process. At the same time, handles 2 are provided on both sides of the fixed box 1 to improve the convenience of carrying. First, the surface of the saline-alkali land is fixed by the fixing component 3 to prevent the sampling position from shifting. At the same time, the sampling component 4 is activated to vertically insert into the deep soil at the sampling position to extract soil samples.

[0034] In one embodiment, such as Figure 2 and Figure 3As shown, the fixing assembly 3 includes a rotating handle 31 rotatably mounted on the top of the fixing box 1. A first gear 32 is fixedly mounted on the bottom end of the rotating handle 31, and the first gear 32 meshes with a second gear 33. A first screw 34 is fixedly mounted on the bottom of the second gear 33, and the first screw 34 is threadedly engaged with a moving platform 35. A connecting rod 36 is hinged to one side of the moving platform 35, and a fixing platform 37 is hinged to the other end of the connecting rod 36. A sliding rod 38 is fixedly mounted on one side of the fixing platform 37. The sliding rod 38 has two sets, and a base 39 is slidably connected to the other end of the sliding rod 38. The bottom of the first screw 34 is rotatably connected to the top of the base 39. Rotating the handle 31 drives the first gear 32 to rotate. When the first gear 32 rotates, the second gear 33 rotates accordingly, driving the first screw 34 to rotate. The rotation of the first screw 34 drives the moving platform 35 to move up and down along the first screw 34, thereby changing the angle between the connecting rod 36 and the horizontal plane. This causes the fixed platform 37 and the sliding rod 38 to move along the slide rail provided for the sliding rod 38 in the base 39. The fixing range of the fixing device can be adjusted, allowing the fixing claw to firmly penetrate saline-alkali soil of different hardness. At the same time, the inherent characteristics of the screw thread allow it to automatically maintain its position after fixing, without the need for an additional locking device.

[0035] In one embodiment, such as Figure 2 and Figure 3 As shown, there are four sets of the second gear 33, the first screw 34, and the connecting rod 36. The second gear 33 corresponds one-to-one with the first screw 34 and the connecting rod 36. The bottom of the fixed platform 37 is provided with multiple sets of insert rods. The four sets of identical gear-screw-connecting rod 36 mechanisms are evenly distributed in a 90° circle to form a stable cross support, ensuring uniform force in all directions.

[0036] In one embodiment, such as Figure 4 and Figure 5 As shown, the sampling assembly 4 includes a drive motor 41 fixedly installed at the bottom of the fixed box 1, a second screw 42 fixedly installed at the output end of the drive motor 41, a drive column 43 threadedly connected to the second screw 42, and a sampler 44 fixedly installed at one end of the drive column 43. By connecting an external controller, the drive motor 41 is started, and the output end of the drive motor 41 drives the second screw 42 to rotate. The second screw 42 drives the drive column 43 to rise and fall along the base 39, so that the sampler 44 is submerged in the saline-alkali land to extract soil.

[0037] In one embodiment, such as Figure 4 and Figure 5As shown, the sampler 44 includes a soil-breaking head 441 fixedly installed at the bottom of the drive column 43, and a sampling tube 442 fixedly installed at the top of the soil-breaking head 441. The sampling tube 442 is provided in multiple sets and is a circular hollow cylinder. The soil-breaking head 441 is a conical head. By adopting a 60° conical head design and making the conical head into tungsten steel, the resistance during soil breaking is reduced when the drive column 43 rotates to break the soil. Multiple soil samples can be obtained at one time. The inner wall of the sampling tube 442 is mirror polished and coated with a silicone oil coating, which reduces the soil sample loss rate while preserving the original pore structure of the soil.

[0038] The above embodiments disclose a conveniently fixed saline-alkali land sampling device, wherein the fixing box 1 serves as the main frame and main structure, and handles 2 are provided on both sides of the fixing box 1 to improve the convenience of carrying. First, the surface of the saline-alkali land is fixed by the fixing component 3 to maintain the stability of the sampling device and prevent the sampling position from shifting. At the same time, the sampling component 4 is activated to vertically insert into the deep soil at the sampling position to extract soil samples.

[0039] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
