Description

Technical Field

[0001] The invention relates to the technical field of soil sampling devices, in particular to a soil microbial ecology test sampling device. Background Art

[0002] Soil microbial ecology experiments are dedicated to studying the community structure, functional characteristics of soil microorganisms, and their interactions with the soil environment. This research is of vital importance in revealing the operating mechanism of soil ecosystems, evaluating the health of soil quality, and exploring the material cycle and energy conversion laws of ecosystems. At present, there are many types of sampling equipment used in soil microbial ecology experiments, and the most common ones are manual soil drills and electric spiral drills. Manual soil drills are relatively simple to operate and have low costs, but they are difficult to operate when facing hard or deep soils, and it is difficult to ensure the accuracy and consistency of sampling. Electric spiral drills can improve sampling efficiency and can penetrate into soils of different depths, but in actual applications, these traditional sampling devices have exposed many problems.

[0003] It is difficult for traditional sampling equipment to ensure the integrity of the samples when obtaining soil samples. In most cases, the samples obtained are often loose and scattered, and the original clear layered structure of the soil is severely damaged. The layered structure of the soil contains a wealth of information. The microbial community structure, activity, and interrelationships with various substances in the soil vary in different soil layers. However, during the sampling process, the original layered structure of the soil is disrupted by the working mode of the traditional sampling equipment, such as the rotating stirring action of the auger when drilling into the soil, or the disturbance of the manual soil drill when taking out the sample. This makes it difficult for subsequent biological analysis to accurately reflect the true distribution and functional characteristics of soil microorganisms in their natural state. Summary of the invention

[0004] 1. Technical issues

[0005] The invention provides a soil microbial ecology test sampling device which can completely collect soil samples, retain the original layered structure, is convenient for subsequent biological analysis, and is easy to operate.

Hole 23, an electric push rod 8 for driving the carrying plate 5 to move up and down is fixedly arranged on the upper end of the U-shaped frame 3; a through hole 9 is arranged at the center of the upper end of the sampling tube 6, a push rod 10 is inserted and connected inside the through hole 9, a push plate 11 is fixedly arranged at one end of the push rod 10 extending into the interior of the sampling tube 6, a spring 12 is sleeved on the push rod 10 and located between the push plate 11 and the top surface of the interior of the sampling tube 6, and the side edge of the push plate 11 is fixedly arranged on the sealing rubber ring 22; a stabilizing component for connecting with the ground to enhance stability is arranged on the outer side of the mobile base 1.

[0031] In this embodiment, as a preferred technical solution, the stabilizing component includes a limit frame 13 fixed on the upper end surface of the mobile base 1, a connecting plate 14 is slidably provided inside the limit frame 13, a circular bottom plate 15 is fixedly provided at the bottom of the connecting plate 14, a plurality of ground plugs 16 are fixedly provided at the bottom of the circular bottom plate 15 along its circumference, and an electric push rod 17 for driving the connecting plate 14 to rise and fall is fixedly provided on the outer side surface of the vertical plate 2.

[0032] In this embodiment, as a preferred technical solution, a slide rail 18 is fixedly provided on the inner wall of the U-shaped frame 3, and sliders 19 matching and sliding with the slide rail 18 are fixedly provided on both sides of the bearing plate 5. A through hole 20 is provided at the top center of the U-shaped frame 3 for the push rod 10 to pass through, and a limit plate 21 is fixedly provided at the upper end of the push rod 10.

[0033] The working principle of the soil microbial ecology test sampling device of the present invention is: the motor 4 provides power to drive the U-shaped frame 3 to rotate to achieve the angle adjustment of the sampling tube 6; the linear thrust generated by the electric push rod 8 is used to drive the bearing plate 5 and the sampling tube 6 to move up and down for sampling; with the help of the combination of the push rod 10, the push plate 11 and the spring 12, the soil sample is completely pushed out; the electric push rod 17 in the stabilizing component controls the lifting and lowering of the connecting plate 14, and uses the ground plug 16 to insert into the ground to enhance the stability of the device.

[0034] The working process of a soil microbial ecology test sampling device of the present invention is as follows:

[0035] 1. Preparation: Move the mobile base 1 to the designated sampling location and connect the external power supply, start the electric push rod 17, the electric push rod 17 extends, pushes the connecting plate 14 to slide downward in the limit frame 13, the connecting plate 14 drives the annular bottom plate 15 to descend, and the ground plug 16 is inserted into the ground to enhance the stability of the mobile base 1.

[0036] 2. Sampling operation: Start the motor 4, which drives the U-shaped frame 3 to rotate between the vertical plates 2, and adjust the U-shaped frame 3 to the sampling position so that the sampling tube 6 is located directly above the sampling hole 23. Then start the electric push rod 8, which extends and pushes the bearing plate 5 to slide downward along the slide rail 18. The bearing plate 5 drives the sampling tube 6 to move downward, and the soil-breaking blade 7 contacts and cuts into the soil. As the sampling tube 6 continues to go deeper, the soil sample enters the sampling tube 6. When the sample enters the sampling tube 6, it pushes the push plate, which exerts a force on the sample under the action of the spring, so that the sample is intact and not loose.

[0037] 3. Sampling completion and transfer: After sampling is completed, the electric push rod 8 retracts, driving the carrier plate 5 and the sampling tube 6 to rise to the initial position. The motor 4 is started again, and the motor 4 drives the U-shaped frame 3 to rotate, adjusting the sampling tube 6 to a horizontal state, which is convenient for subsequent material collection.

[0038] 4. Take out the sample: push the push rod 10 to generate thrust on the push plate 11. With the cooperation of the sealing rubber ring 22, the push plate 11 fits tightly against the inner wall of the sampling tube 6 to completely push out the soil sample in the sampling tube 6 to complete the sample collection.

[0039] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
