Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil testing device technology, and in particular to a sample rapid positioning mechanism that assists in soil testing. Background Technology
[0002] In the soil testing process, the soil sampling device plays a crucial role. It is a key tool for obtaining original soil samples and is directly related to the accuracy and representativeness of the test results. By accurately collecting soil samples from different depths and areas, the true condition of the soil can be fully reflected, providing a reliable sample basis for soil fertility assessment, pollution detection, and analysis of suitable crop planting.
[0003] However, in the existing technology, the actual soil testing environment is complex and variable, with many factors interfering with the initial position control. In mountainous areas, the terrain is undulating, making it difficult to place the sampling device stably on the sloping ground and determine the horizontal starting position, which leads to a decrease in the positioning accuracy during sampling and causes inaccurate sampling. Utility Model Content
[0004] The purpose of this invention is to address the problem in the existing technology that the actual soil testing environment is complex and variable, with many factors interfering with the initial position control. In mountainous areas, the terrain is undulating, making it difficult to stably place the sampling device on sloping ground and determine the horizontal starting position. Therefore, this invention proposes a sample rapid positioning mechanism to assist in soil testing.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a rapid sample positioning mechanism for assisting soil testing, comprising a support mechanism, an adjustment mechanism fixedly connected to the upper part of the support mechanism, a sampler installed inside the adjustment mechanism, the support mechanism including a support platform, a fixing plate fixedly connected to the side of the support platform, a threaded support rod rotatably connected to the surface of the fixing plate, a threaded plate threadedly connected to the surface of the threaded support rod, a support leg fixedly connected to the side of the threaded plate, the adjustment mechanism including a first slide rail, a first slider slidably connected inside the first slide rail, a second slide rail fixedly connected to the upper part of the first slider, a second slider slidably connected inside the second slide rail, a first connecting plate fixedly connected to the side of the second slider, and a clamping assembly provided on the side of the first connecting plate.
[0006] Preferably, a guide rod is fixedly connected to the bottom of the fixing plate, a guide block is slidably connected to the surface of the guide rod, and the guide block is fixedly connected to the side of the support leg.
[0007] Preferably, the bottom of the support leg is fixedly connected with an anti-slip rubber pad.
[0008] Preferably, a lead screw is rotatably connected to the surface of the first slide rail, and the lead screw is threadedly connected to the first slider.
[0009] Preferably, a second lead screw is rotatably connected to the surface of the second slide rail, and the second lead screw is threadedly connected to the second slider.
[0010] Preferably, the clamping assembly includes a No. 3 lead screw, which is threadedly connected to a No. 1 connecting plate. A No. 2 connecting plate is rotatably connected to the end of the No. 3 lead screw, and a clamping plate is fixedly connected to the side of the No. 2 connecting plate. The clamping plate is clamped and fixed to the sampler.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0012] 1. In this utility model, the support mechanism keeps the support platform horizontal, enabling the sampler installed on it to perform sampling work in the correct posture. This effectively solves the problem of the sampler tilting due to ground inclination, which causes the sampling position to deviate from the target area. This greatly improves the positioning accuracy of the sampling and ensures that the collected soil samples accurately reflect the soil characteristics of the target area. Secondly, in terms of stability, the support legs form a stable support structure with the ground, which greatly enhances the stability of the entire device in complex terrain and ensures the continuity and accuracy of the sampling process. Furthermore, the operation of this solution is relatively simple. Testing personnel do not need complicated tools and professional skills; they can simply adjust the system by rotating the threaded support rod, which improves work efficiency and reduces the difficulty of carrying out soil testing in complex environments.
[0013] 2. In this utility model, the sampling machine is clamped and fixed by rotating the No. 3 lead screw, ensuring that the sampling machine will not shake or shift during the entire sampling process, providing a solid foundation for accurate sampling. In terms of position adjustment, the cooperation of the No. 1 and No. 3 lead screws enables large-range rapid movement and small-range precise fine adjustment, allowing the sampling machine to quickly and accurately reach any required sampling position, greatly improving work efficiency. During sampling, rotating the No. 2 lead screw drives the sampling machine to move steadily downwards, and with the guiding effect of the No. 2 slide rail, the stability and verticality of the sampling process are ensured, effectively improving the quality of the collected soil samples and making the test results more accurately reflect the actual situation of the soil.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0021] Example 1: As Figures 1-4 As shown, this utility model provides a rapid sample positioning mechanism to assist in soil testing, including a support mechanism 1. An adjustment mechanism 2 is fixedly connected to the upper part of the support mechanism 1, and a sampler 3 is installed inside the adjustment mechanism 2. The support mechanism 1 includes a support platform 11, a fixing plate 12 is fixedly connected to the side of the support platform 11, a threaded support rod 13 is rotatably connected to the surface of the fixing plate 12, a threaded plate 14 is threadedly connected to the surface of the threaded support rod 13, a support leg 15 is fixedly connected to the side of the threaded plate 14, a guide rod 16 is fixedly connected to the bottom of the fixing plate 12, a guide block 17 is slidably connected to the surface of the guide rod 16, the guide block 17 is fixedly connected to the side of the support leg 15, and an anti-slip rubber pad is fixedly connected to the bottom of the support leg 15.
[0022] The specific settings and functions of this embodiment are described in detail below. Based on the flatness of the sampling ground, the height of the support leg 15 is adjusted by rotating the threaded support rod 13, which in turn drives the threaded plate 14 to adjust along the threaded support rod 13. By adjusting the height of multiple independent support legs 15 at the bottom of the support platform 11, the upper part of the support platform 11 is kept horizontal, and a stable support is formed between the support legs 15 and the ground. This provides stable support for the sampler 3, ensuring that the sampler 3 remains stable during sampling. Regarding positioning accuracy, the horizontal position of the support platform 11 allows the sampler 3 mounted on it to perform sampling work in the correct posture. Previously, the sampler 3 would tilt due to ground inclination, thus affecting the sampling accuracy. The problem of sample location deviating from the target area has been effectively solved, greatly improving the positioning accuracy of sampling and ensuring that the collected soil samples accurately reflect the soil characteristics of the target area. Secondly, in terms of stability, the support leg 15 forms a stable support structure with the ground, which greatly enhances the stability of the entire device in complex terrain. Even in severe weather conditions such as strong winds that may be encountered in mountainous areas, the device is not prone to shaking or displacement, ensuring the continuity and accuracy of the sampling process. Furthermore, the operation of this solution is relatively simple. Testing personnel do not need complicated tools and professional skills. They can complete the adjustment simply by rotating the threaded support rod 13, which improves work efficiency and reduces the difficulty of carrying out soil testing in complex environments.
[0023] Example 2: Figures 1-4 As shown, the adjustment mechanism 2 includes a first slide rail 21, a first slider 22 is slidably connected inside the first slide rail 21, a second slide rail 24 is fixedly connected to the upper part of the first slider 22, a second slider 25 is slidably connected inside the second slide rail 24, a first connecting plate 27 is fixedly connected to the side of the second slider 25, a clamping assembly is provided on the side of the first connecting plate 27, a first lead screw 23 is rotatably connected to the surface of the first slide rail 21, the first lead screw 23 is threadedly connected to the first slider 22, a second lead screw 26 is rotatably connected to the surface of the second slide rail 24, the second lead screw 26 is threadedly connected to the second slider 25, the clamping assembly includes a third lead screw 28, the third lead screw 28 is threadedly connected to the first connecting plate 27, a second connecting plate 29 is rotatably connected to the end of the third lead screw 28, a clamping plate 210 is fixedly connected to the side of the second connecting plate 29, and the clamping plate 210 is clamped and fixed to the sampler 3.
[0024] The overall effect of this embodiment is as follows: the sampler 3 is placed inside the clamping plate 210. By rotating the third lead screw 28, the second connecting plate 29 and the clamping plate 210 are pushed to clamp and fix the sampler 3. At the same time, rotating the third lead screw 28 can adjust the position of the sampler 3 on the upper part of the support platform 11. Similarly, rotating the first lead screw 23 drives the first slider 22 to slide along the first slide rail 21, adjusting the position of the sampler 3 so that the sampler 3 reaches the sampling position. Finally, rotating the second lead screw 26 drives the second slider 25 to slide downward along the second slide rail 24, so that the sampler 3 can stably perform the sampling operation downward. In terms of fixation, rotating the third lead screw 28 drives the clamping plate 29 to fix the sampler 3. The 10 clamps secure the sampler 3, ensuring it remains stable and doesn't shake or shift during the sampling process, providing a solid foundation for accurate sampling. For position adjustment, the cooperation of lead screw 23 (number one) and lead screw 28 (number three) enables both large-range rapid movement and small-range precise fine-tuning, allowing the sampler 3 to quickly and accurately reach any desired sampling position, significantly improving work efficiency. During sampling, rotating lead screw 26 drives the sampler 3 downwards stably, and the guidance of slide rail 24 ensures stability and verticality during the sampling process, effectively improving the quality of the collected soil samples and making the test results more accurately reflect the actual soil conditions.
[0025] The usage and working principle of this device are as follows: Based on the flatness of the sampling ground, the height of the support leg 15 is adjusted by rotating the threaded support rod 13 to drive the thread plate 14 along the threaded support rod 13. By adjusting the height of multiple independent support legs 15 at the bottom of the support platform 11, the upper part of the support platform 11 is kept horizontal, and a stable support is formed between the support legs 15 and the ground, thereby providing stable support for the sampler 3.
[0026] The sampler 3 is placed inside the clamping plate 210. By rotating the third lead screw 28, the second connecting plate 29 and the clamping plate 210 are pushed to clamp and fix the sampler 3. At the same time, by rotating the third lead screw 28, the position of the sampler 3 on the upper part of the support platform 11 can be adjusted. Similarly, rotating the first lead screw 23 drives the first slider 22 to slide along the first slide rail 21 to adjust the position of the sampler 3 so that the sampler 3 reaches the sampling position. Finally, rotating the second lead screw 26 drives the second slider 25 to slide downward along the second slide rail 24 so that the sampler 3 can stably perform the sampling operation downward.
[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
