Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, specifically to a soil testing drilling and sampling device. Background Technology

[0002] Environmental science is a discipline that studies the geographical, physical, chemical, and biological aspects of the environment. It provides comprehensive, quantitative, and interdisciplinary methods for studying environmental systems. Because most environmental problems involve human activities, knowledge from economics, law, and social sciences can often be applied to environmental science research. It is a science that studies the interaction between human social development activities and the laws of environmental evolution, seeking pathways and methods for the co-evolution and sustainable development of human society and the environment.

[0003] When using soil sampling devices, the lack of a corresponding fixing device means that manual pressing can cause the device to tilt, and uneven ground makes it difficult to ensure stability, preventing the acquisition of soil samples at the desired depth. This results in biased soil sample data. Furthermore, if the sampling part is tilted during sampling, it may be impossible to accurately obtain soil samples at the target depth, leading to a decrease in the representativeness of the samples and an inability to truly reflect the actual soil conditions. To address these issues, a drilling soil sampling device for soil testing is proposed. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a soil sampling device for drilling, which solves the problems of existing soil sampling devices. These devices lack a proper fixing mechanism, leading to manual pressing and potential tilting. Uneven ground conditions also compromise stability, preventing the acquisition of soil samples at the desired depth and resulting in data inaccuracies. Furthermore, if the sampling area is tilted during sampling, it may be impossible to accurately obtain soil samples at the target depth, reducing the representativeness of the samples and failing to accurately reflect the actual soil conditions.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a soil sampling device for drilling, comprising a fixed plate and an adjusting plate. At least three adjusting threaded rods are threadedly connected to the surface of the fixed plate. A rotating handwheel is fixedly connected to the bottom of each of the three adjusting threaded rods, and a spherical block is fixedly connected to the top of each of the three adjusting threaded rods. A rotating block is fixedly connected to the bottom of the adjusting plate at a position corresponding to the spherical block. The spherical block is rotatably connected inside the rotating block. A sampling component is provided in the middle of the upper surface of the adjusting plate, and a clamping component is provided on the outer side of the upper surface of the adjusting plate. Three sets of height adjusting components are fixedly connected to the bottom of the fixed plate.

[0006] Preferably, the sampling component includes a mounting plate, which is disposed above the adjustment plate. A lead screw stepper motor is fixedly mounted on the middle of the upper surface of the mounting plate. Guide rods are slidably connected to the upper surface of the mounting plate and the left and right sides of the lead screw stepper motor. Connecting plates are fixedly connected to the upper and lower ends of the two guide rods.

[0007] Preferably, the upper and lower ends of the lead screw in the middle of the lead screw stepper motor are fixedly connected to the two connecting plates respectively, and two connecting strips are fixedly connected to the bottom of the lower connecting plate, and sampling cylinders are detachably connected to the bottom of the two connecting strips.

[0008] Preferably, the height adjustment assembly includes a telescopic sleeve, a first connecting lug is fixedly connected to the top of the telescopic sleeve, a rotating seat is rotatably connected to the upper end of the first connecting lug, and the rotating seat is fixedly connected to the bottom of the fixed plate.

[0009] Preferably, a telescopic rod is slidably connected inside the telescopic sleeve, and a locking sleeve is threadedly connected to the outside of the telescopic sleeve at the connection position of the telescopic rod. A second connecting lug is fixedly connected to the lower end of the telescopic rod, and a fixing member is rotatably connected to the lower end of the second connecting lug.

[0010] Preferably, the clamping assembly includes a rotating column, which is fixedly connected to the rear side of the upper surface of the adjustment plate. A semi-circular first clamp is rotatably connected to the upper outer side of the rotating column, and a semi-circular first groove is formed on the inner side of the first clamp.

[0011] Preferably, a semi-circular second clamp is rotatably connected to the lower outer end of the rotating column, and a semi-circular second groove is provided on the inner side of the second clamp. Both the first clamp and the second clamp are fixedly connected to a locking ring for locking at the end away from the rotating column.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. This utility model adjusts the level of the adjusting plate by adjusting the threaded fit between the threaded rod and the fixed plate, thereby ensuring that the sampling component can remain parallel to the ground. This ensures that the sampling depth is not affected by the tilt of the device during sampling, which helps to ensure that each sampling accurately reflects the soil conditions at a specific level.

[0014] 2. This utility model, by setting a height adjustment component, can effectively support the sampling device during sampling, preventing the sampling device from tilting. The height adjustment component allows the operator to easily adjust the height of the sampling device as needed, adapting to different terrains and sampling requirements, enhancing the flexibility and convenience of operation. The stable support structure reduces the frequency of corrections required by the operator when adjusting the sampling device, lowering the probability of errors.

[0015] 3. This utility model incorporates a clamping component, which allows the sampling component to be replaced without moving its position by clamping or releasing the component. This avoids wasting time due to position adjustments and improves work efficiency. Since the sampling component can be replaced without moving the device, the stability of the device is maintained, thus avoiding tilting or instability caused by position adjustments and ensuring sampling accuracy.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0026] Reference Figure 1-7 As shown, a soil sampling device for soil testing includes a fixed plate 1 and an adjusting plate 2. At least three adjusting threaded rods 5 are threadedly connected to the surface of the fixed plate 1. A rotating handwheel 6 is fixedly connected to the bottom of each of the three adjusting threaded rods 5. A spherical block 4 is fixedly connected to the top of each of the three adjusting threaded rods 5. A rotating block 3 is fixedly connected to the bottom of the adjusting plate 2 at a position corresponding to the spherical block 4. The spherical block 4 is rotatably connected inside the rotating block 3. The rotatable connection design between the spherical block 4 and the rotating block 3 allows the adjusting plate 2 to move up and down while also making a certain degree of vertical fine adjustment as needed, increasing the flexibility of the device. A sampling component 7 is provided in the middle of the upper surface of the adjusting plate 2, and a clamping component 9 is provided on the outer side of the upper surface of the adjusting plate 2. Three sets of height adjusting components 8 are fixedly connected to the bottom of the fixed plate 1.

[0027] Reference Figure 5 As shown, the sampling component 7 includes a mounting plate 701, which is positioned above the adjustment plate 2. A lead screw stepper motor 702 is fixedly mounted on the middle of the upper surface of the mounting plate 701. Guide rods 703 are slidably connected to the upper surface of the mounting plate 701 and the left and right sides of the lead screw stepper motor 702. Connecting plates 704 are fixedly connected to the upper and lower ends of the two guide rods 703.

[0028] Reference Figure 5 As shown, the upper and lower ends of the lead screw in the middle of the lead screw stepper motor 702 are fixedly connected to two connecting plates 704 respectively. Two connecting strips 705 are fixedly connected to the bottom of the lower connecting plate 704. The sampling cylinder 706 is detachably connected to the bottom of the two connecting strips 705. The drive of the lead screw stepper motor 702 enables the sampling cylinder 706 to move up and down automatically, realizing automated sampling and improving work efficiency. The lead screw stepper motor 702 can be an LA-through shaft linear stepper motor. The detachable connection design between the sampling cylinder 706 and the connecting strips 705 makes it easy to replace sampling cylinders 706 of different specifications to adapt to soil sampling needs at different depths.

[0029] Reference Figure 6 As shown, the height adjustment component 8 includes a telescopic sleeve 801, a first connecting ear 802 fixedly connected to the top of the telescopic sleeve 801, a rotating seat 803 rotatably connected to the upper end of the first connecting ear 802, and the rotating seat 803 fixedly connected to the bottom of the fixed plate 1. The sliding connection design between the telescopic sleeve 801 and the telescopic rod 804 enables the device to adapt to soil sampling needs at different heights.

[0030] Reference Figure 6As shown, a telescopic rod 804 is slidably connected inside the telescopic sleeve 801. A locking sleeve 805 is threadedly connected to the outside of the telescopic sleeve 801 at the connection position of the telescopic rod 804. A second connecting lug 806 is fixedly connected to the lower end of the telescopic rod 804. A fixing piece 807 is rotatably connected to the lower end of the second connecting lug 806. The locking sleeve 805 ensures the stability of the telescopic rod 804 after it is adjusted to a suitable height and prevents it from rising or falling due to external forces. Its principle can be referred to as the fixing structure of a tripod.

[0031] Reference Figure 7 As shown, the clamping assembly 9 includes a rotating column 901, which is fixedly connected to the rear side of the upper surface of the adjusting plate 2. A semi-circular first clamp 902 is rotatably connected to the upper outer side of the rotating column 901, and a semi-circular first groove 903 is provided on the inner side of the first clamp 902.

[0032] Reference Figure 7 As shown, a semi-circular second clamp 904 is rotatably connected to the lower outer end of the rotating column 901. A semi-circular second groove 905 is provided on the inner side of the second clamp 904. The ends of the first clamp 902 and the second clamp 904 away from the rotating column 901 are fixedly connected to a locking ring 906 for locking. The first clamp 902 and the second clamp 904 are quickly locked by the locking ring 906, so that the mounting plate 701 is stuck in the first groove 903 and the second groove 905 and limited, so that the mounting plate 701 is quickly fixed on the adjusting plate 2, which improves the working efficiency.

[0033] Working principle: Before use, firstly, open the first clamp 902 and the second clamp 904 around the rotating column 901. Then, pass the sampling cylinder 706 through the hole in the center of the adjusting plate 2, so that the mounting plate 701 is placed above the adjusting plate 2. Next, close the first clamp 902 and the second clamp 904 and lock them with the locking ring 906. Then, pull the telescopic rod 804 out from the telescopic sleeve 801, adjust it to a suitable height, and lock it with the locking sleeve 805. Then, open the three sets of height adjustment components 8 to a suitable opening degree, insert the fixing piece 807 into the ground for fixation, and then turn the handwheel. The drive adjustment screw 5 rotates, thereby pushing or pulling the adjustment plate 2 to move up and down, thus adjusting the level of the adjustment plate 2. The level can be observed by placing an external spirit level on the adjustment plate 2. During sampling, the lead screw stepper motor 702 works to make the lead screw in the middle move linearly, causing the sampling cylinder 706 to move downward to perform circumferential sampling of the ground soil. If it is necessary to obtain samples from deeper soil, simply remove the soil inside the sampling cylinder 706 after sampling, and then repeat the above sampling operation. Alternatively, sampling cylinders 706 of different heights can be used for sampling.
