Technical Field

[0001] The utility model relates to the technical field of sampling devices for soil detection, in particular to a sampling device for soil detection. Background Art

[0002] Soil testing is the process of analyzing and testing soil samples to determine their chemical and physical properties. This test can help farmers understand the soil's fertility level, pH value, organic matter content and other information, thereby guiding planting and fertilization. Existing soil testing usually uses a drill to drill a hole on the top of the soil, then inserts the sampling device into the hole, and uses an external pile driver to nail the sampling device into the hole, forcing the soil into the device, and then removes the sampling device to complete the soil sampling. However, when the sample is taken out, it may be in contact with the air for a long time, which will cause the internal structure to change and affect the test value. At the same time, when the sampling device is sampling, it may cause vibration due to the drive of the pile driver, which will affect the sampling speed. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a technical solution, please refer to Figure 1 A soil testing sampling device comprises: a sampling tube 1, a conical tube bottom 2 and a sample tube 3. The conical tube bottom 2 can increase the smoothness of the sampling tube 1 being hammered into the soil. The sample tube 3 can collect soil samples. The top of the sampling tube 1 is threadedly connected with a tube cover 11, and the bottom of the tube cover 11 is connected to the top of the sample tube 3. The top of the tube cover 11 can be provided with a plum blossom groove or a straight groove, so that the staff can drive the sampling tube 1 with a tool. The tube cover 11 can open the top of the sampling tube 1. The sample tube 3 is closed and then fixed. The interior of the sampling tube 1 is connected with guide rings 12 at equal intervals. The inner bottom of the sampling tube 1 is fixedly connected with a load-bearing ring 13. The interior of the sampling tube 1 is provided with an annular groove 14. The interior of the annular groove 14 is provided with a short groove. The short groove facilitates the movement of the first inclined rod 44 and the second inclined rod 47. The guide ring 12 can limit the sample tube 3, and the load-bearing ring 13 can support the sample tube 3. The conical tube bottom 2 is installed at the bottom of the sampling tube 1, and the sample tube 3 is inserted into the interior of the sampling tube 1.

[0024] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 A closing mechanism 4 is installed above the sampling tube 1, and the closing mechanism 4 includes a top ring 41. The top ring 41 can press the vertical arm 43 to move, and can also drive the vertical arm 43 and the sampling tube 1 to return. A magnetic ring 42 is embedded on the top of the top ring 41, and the magnetic ring 42 is a ring-shaped magnetic block. The magnetic ring 42 facilitates the top ring 41 to be adsorbed and driven by the external magnetic block.

[0025] Both ends of the bottom of the top ring 41 are connected to vertical arms 43, and one end of the vertical arm 43 close to the sample tube 3 is hingedly connected to a first inclined rod 44, and the first inclined rod 44 can be driven by the vertical arm 43. The bottom of the first inclined rod 44 is hingedly connected to a push rod 45, and the push rod 45 can be driven by the first inclined rod 44. Both ends of the interior of the sampling tube 1 are fixedly connected to guide rail slot blocks 15, and a guide rail is provided on the top of the guide rail slot block 15.

[0026] The guide rail at the top of the guide rail slot block 15 is slidably connected to a slider, and the slider is connected to the bottom of the push rod 45. The guide rail slot block 15 cooperates with the slider to guide the push rod 45 so that the push rod 45 moves linearly. The end of the push rod 45 close to the sample tube 3 is connected to a C-shaped ring 46, and the C-shaped ring 46 can clamp and fix the sample tube 3. The lower part of the outside of the vertical arm 43 is connected to a second inclined rod 47 through a hinge, and the second inclined rod 47 can drive the sealing plate 48 to move, and the other end of the second inclined rod 47 is connected to the sealing plate 48 through a hinge, and the sealing plate 48 can close the bottom of the sampling tube 1.

[0027] The bottom of the sealing plate 48 is fixedly connected with a guide block 16, and the guide block 16 is slidably set on the top of the sampling tube 1. The guide block 16 can guide the sealing plate 48 to make the sealing plate 48 move linearly. The vertical arm 43 is set through the interior of the sampling tube 1 and the conical tube bottom 2. A spring 49 is connected between the vertical arm 43 and the conical tube bottom 2. The two sealing plates 48 are closed to match the bottom groove of the sampling tube 1, and the top of the sealing plate 48 is polished.

[0028] In this scheme, a hole is first drilled in the ground by a punch, the tube cover 11 is rotated to open, and then the sample tube 3 is inserted into the interior of the sampling tube 1. Then the tube cover 11 is returned to its original position, and the assembled sampling tube 1 is inserted into the hole. The tube cover 11 is hammered into the ground by an external pile driver. At the same time, when the top ring 41 is hit and drops by its own weight, it will be transmitted through the vertical arm 43, and then the push rod 45 and the C-shaped ring 46 will be driven to move through the first inclined rod 44. When the two C-shaped rings 46 move relative to each other, the position of the sample tube 3 is fixed and limited. At the same time, the vertical arm 43 is transmitted through the second inclined rod 47, and then the sealing plate 48 is pulled to move. After the two sealing plates 48 move away from each other, the sealing of the bottom of the sampling tube 1 is released. At this time, the soil sample will enter the interior of the sample tube 3 through the bottom of the sampling tube 1 for collection;

[0029] After the sample is taken, the external magnetic block is attracted to the magnetic ring 42, and the top ring 41 is dragged, and then the sampling tube 1 is taken out. At the same time, when the top ring 41 is dragged, the push rod 45 and the sealing plate 48 will move in the opposite direction, and the sealing plate 48 will release the restriction on the sample tube 3, and the sealing plate 48 will seal the bottom of the sample tube 3;

[0030] When sampling and collecting soil samples, the position of the sample tube 3 is automatically fixed and limited to prevent the sample tube 3 from vibrating when being driven by an external pile driver, thereby reducing the soil collection speed. When the soil collection is completed, the sealing plate 48 automatically seals the bottom of the sample tube 3 to prevent the soil inside from reacting with external oxygen and sunlight when the sample tube 3 is returned and taken out, thereby reducing the accuracy of the soil detection value.

[0031] When the sampling tube 1 is completely pulled out by the magnetic ring 42, the staff can open the tube cover 11, take out the sample tube 3 from the inside of the sampling tube 1, and then seal the bottom of the sample tube 3 with the closing cover to complete the sampling of the sample.
