Description

Technical Field

[0001] The present invention relates to the field of soil sampling, and in particular to a soil quality assessment device and a use method thereof. Background Art

[0002] Soil structure and quality affect the physical, chemical and biological processes of the soil, such as the retention and movement of water in the soil, the circulation and transformation of nutrients, and the survival and activity of microorganisms.

[0003] Research on soil structure and quality helps to understand and predict how soil responds to external environmental changes, such as climate change and changes in farming methods, thereby providing a scientific basis for agricultural production, helping farmers choose appropriate farming and irrigation strategies, and improving crop yields and quality. Before evaluating soil structure and quality, soil sampling is required, and then the soil samples are sent to analysis equipment for analysis and evaluation. However, it is difficult to remove samples during the sampling process with existing sampling equipment, especially for sampling deep soil. There are too many soil samples in the sampling tube. In the process of removing the soil sample from the sampling tube, the existing technology usually uses a combination of pushing and knocking to remove the soil sample, that is, the soil sample is squeezed when it is taken out of the sampling rod, causing local compression of the soil sample, that is, part of the soil sample structure is loose and squeezed, thereby compressing the soil sample, and the compressed soil sample cannot determine the corresponding depth of the soil, thereby affecting the subsequent analysis and evaluation of the soil sample. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art that soil samples are usually taken out by a combination of pushing and knocking, that is, the soil sample is squeezed when it is taken out from the sampling rod, causing local compression of the soil sample, that is, part of the soil sample structure is loose and squeezed, thereby compressing the soil sample, and the compressed soil sample cannot determine the corresponding depth of the soil, thereby affecting the subsequent analysis and evaluation of the soil sample, the present invention provides a soil quality assessment device and a method for using the same.

[0005] The technical implementation scheme of the present invention is: a soil quality assessment device, including a fixed frame, a slide rail, a first connecting plate and a sampling barrel; the two fixed frames are fixedly connected with the slide rails; all the slide rails are slidably connected with the first connecting plate; the first connecting plate is fixedly connected with the sampling barrel; it also includes a second connecting plate, a fixed plate, a limiting barrel, a connecting shaft, a driving assembly and a separating assembly; the fixed frame can be provided with a detection device for performing on-site detection of the collected soil samples; a plurality of second connecting plates are connected to the first connecting plate; all the second connecting plates are fixedly connected with the fixed plate; the fixed frame is connected with a driving assembly, and the driving assembly is used to drive the first connecting plate, the sampling barrel, the second connecting plate and the fixed plate to move up and down; the limiting barrel is fixedly connected with the fixed plate; the limiting barrel is rotatably connected with a plurality of connecting shafts; all the connecting shafts are connected with a plurality of separating assemblies;

[0006] Each partition assembly includes a first limiting plate, a telescopic cloth and a shifting rod; each connecting shaft is fixedly connected to a first limiting plate; the inner side of each first limiting plate is fixedly connected to a telescopic cloth; the other end of each telescopic cloth is fixedly connected to another adjacent first limiting plate; and each connecting shaft is fixedly connected to a shifting rod.

[0008] Furthermore, the first connecting plate and the second connecting plate are arranged in a quick-release structure.

[0009] Furthermore, the lower parts of the sampling tube and the limiting tube are arranged in a conical structure.

[0010] Furthermore, a blade is arranged on the first limiting plate.

[0011] Furthermore, it also includes a second limit plate; a plurality of limit groups are connected to the limit cylinder; each limit group is composed of a plurality of second limit plates, and the second limit plates on the same limit group are fixedly connected to each other; each limit group is located between two adjacent partition components.

[0012] Furthermore, the second limiting plate and the limiting cylinder are arranged in a quick-release structure.

[0013] Furthermore, a blade is provided at the lower portion of the second limiting plate.

[0014] A method for using a soil quality assessment device comprises the following steps:

[0015] Step 1: Place the sampling equipment in the area where soil assessment is required and then carry out sampling work;

[0016] Step 2: During the sampling process, the soil sample is protected by the first limiting plate and the telescopic cloth to prevent leakage of the soil sample when the soil sample is taken out, resulting in loss of the soil sample;

[0017] Step 3: Take out the soil sample and seal it with the first limit plate and the telescopic cloth to prevent the soil sample from being subjected to excessive squeezing force as a whole, which may cause the soil sample to be damaged;

[0022] 2. The spiral agitator is inserted into the soil by rotating and limiting the position through the limiting cylinder. The spiral agitator mixes the layered soil samples originally collected in the limiting cylinder and transports them to the external collection device, thereby realizing the collection of mixed soil samples and layered soil samples, avoiding the need to mix soil samples of different depths during subsequent soil sample analysis, thereby saving time for subsequent mixing of soil samples and facilitating subsequent analysis and evaluation of different soil samples.

[0023] 3. When the lower part of the sampling tube is sealed by the blocking structure, the soil sample in the sampling tube is divided into seven parts by the blocking structure. Therefore, when the soil sample is taken out from the sampling tube by the cooperation of the limiting tube, the first limiting plate and the telescopic cloth, the soil sample is pushed by the eight groups of blocking structures, thereby reducing the degree of compression of the soil sample when the soil sample is pushed out, that is, effectively reducing the degree of compression of the soil sample when it is taken out, which is conducive to ensuring the integrity of the soil sample.

[0037] The driving assembly includes a multi-stage push rod 15, a third connecting plate 16 and a connecting rod 17; each fixed frame 1 is fixedly connected to the multi-stage push rod 15; the telescopic end of each multi-stage push rod 15 is fixedly connected to the third connecting plate 16; each third connecting plate 16 is fixedly connected to a connecting rod 17; all the connecting rods 17 are fixedly connected to the fixed plate 6.

[0038] Each partition assembly includes a first limiting plate 12, a telescopic cloth 13 and a lever 14; each connecting shaft 11 is fixedly connected to a first limiting plate 12; the inner side of each first limiting plate 12 is fixedly connected to a telescopic cloth 13; the other end of each telescopic cloth 13 is fixedly connected to another adjacent first limiting plate 12; each connecting shaft 11 is fixedly connected to a lever 14.

[0039] It also includes a mixing component, which includes a DD motor 7, a connecting cylinder 8 and a spiral agitator 9; the DD motor 7 is bolted to the fixed plate 6; the rotating part of the DD motor 7 is fixedly connected to the connecting cylinder 8, and the connecting cylinder 8 is rotatably connected to the fixed plate 6; the spiral agitator 9 is fixedly connected to the connecting cylinder 8; the spiral agitator 9 is located in the limiting cylinder 10.

[0040] The first connecting plate 3 and the second connecting plate 5 are arranged in a quick-release structure to facilitate quick separation.

[0041] The lower parts of the sampling tube 4 and the limiting tube 10 are arranged in a conical structure, so as to facilitate insertion into the soil.

[0042] The first limiting plate 12 is provided with a blade to facilitate the division of the soil sample.

[0043] First, the staff installs the soil quality assessment equipment on the external mobile device, and uses the bolt fixing frame 1 to fix it on the external mobile device, then controls the external mobile device to drive the fixing frame 1 to be placed where sampling is required, and then controls the multi-stage push rod 15 to contract and drive the third connecting plate 16 to move downward, the third connecting plate 16 drives the connecting rod 17 to move downward, the connecting rod 17 drives the fixing plate 6 to move downward, the fixing plate 6 drives the first connecting plate 3, the sampling tube 4, the second connecting plate 5, the limiting tube 10, the connecting shaft 11, the first limiting plate 12, the telescopic cloth 13 and the lever 14 to move downward, that is, drives the two first connecting plates 3 to move downward on the two slide rails 2, and keeps the sampling tube 4 vertically downward through the slide rails 2 and the first connecting plate 3. The first connecting plate 3 drives the sampling tube 4 to be inserted into the soil, and the fixing plate 6 drives the limiting tube 10 to be inserted into the soil, so that the soil sample is collected by the sampling tube 4 and the limiting tube 10 to form two groups of soil samples. After the soil sample collection is completed and the sampling tube 4 and the limiting tube 10 are separated from the soil, the staff first turns the three levers 14 to rotate, so that the levers 14 drive the connecting shaft 11 to rotate, and the connecting shaft 11 drives the first limiting plate 12 to rotate with the connecting shaft 11 as the rotation center, so that the first limiting plate 12 contacts the inner wall of the sampling tube 4, that is, the soil sample is divided by the blade arranged on the first limiting plate 12, and at the same time, the first limiting plate 12 stretches the telescopic cloth 13 to form a blocking structure. Figure 7As shown, the blocking structure formed by the first limiting plate 12 and the telescopic cloth 13 blocks the lower part of the sampling tube 4, so as to prevent the soil sample in the sampling tube 4 from falling back into the soil when the sampling tube 4 and the limiting tube 10 are separated from the soil, thereby affecting the soil sample collection and the subsequent soil evaluation. In addition, by arranging a spiral agitator 9 in the limiting tube 10, arranging a DD motor 7 and a connecting tube 8 on the fixing plate 6, and connecting an external collecting device to the connecting tube 8, during the soil sample collection process, that is, when the limiting tube 10 is inserted into the soil, the DD motor 7 is controlled to drive the connecting tube 8 to collect the soil sample. The connecting tube 8 rotates, and the connecting tube 8 drives the spiral stirrer 9 to rotate, that is, the spiral stirrer 9 rotates and cooperates to be inserted into the soil, and is limited by the limiting tube 10. The spiral stirrer 9 mixes the layered soil samples originally collected in the limiting tube 10 and transports them to the external collecting device, thereby realizing the collection of mixed soil samples and layered soil samples, avoiding the need to mix soil samples of different depths in subsequent soil sample analysis, thereby saving the time for subsequent mixing of soil samples, facilitating the subsequent analysis and evaluation of different soil samples, and then controlling the multi-stage push rod 15 to push The third connecting plate 16 moves upward, the third connecting plate 16 drives the connecting rod 17 to move upward, the connecting rod 17 drives the fixing plate 6 to move upward, the fixing plate 6 drives the parts connected thereto upward, that is, the sampling tube 4 and the limiting tube 10 move upward and separate from the soil, the first connecting plate 3 moves to contact with the uppermost end of the slide rail 2, at this time the staff uses a tool to disassemble the second connecting plate 5 and the first connecting plate 3, and at the same time removes the peripheral collecting device from the connecting tube 8, and then controls the multi-stage push rod 15 to further push the third connecting plate 16 and the connecting rod 1 7 moves upward, and then the connecting rod 17 drives the fixing plate 6 to move upward, and the fixing plate 6 drives the parts connected thereto to move upward, and the fixing plate 6 drives the DD motor 7, the connecting cylinder 8, the spiral agitator 9, the limiting cylinder 10, the connecting shaft 11, the first limiting plate 12, the telescopic cloth 13 and the shifting rod 14 to move upward, that is, the soil sample is taken out of the sampling cylinder 4 by the limiting cylinder 10, the first limiting plate 12 and the telescopic cloth 13, thereby realizing the rapid removal operation of the soil sample, without the need to manually use the push plate to take out the soil sample in the sampling cylinder 4, saving manpower.

[0044] Furthermore, when the lower part of the sampling tube 4 is blocked by the blocking structure formed by the first limiting plate 12 and the telescopic cloth 13, eight groups of blocking structures are formed, and the distance between each group of blocking structures is the same. Therefore, when the lower part of the sampling tube 4 is blocked by the blocking structure, the soil sample in the sampling tube 4 is divided into seven parts by the blocking structure. Therefore, when the soil sample is taken out of the sampling tube 4 by the limiting tube 10, the first limiting plate 12 and the telescopic cloth 13, the soil sample is pushed by the eight groups of blocking structures, thereby reducing the degree of compression of the soil sample when the soil sample is pushed out, that is, effectively reducing the degree of compression of the soil sample when it is taken out, which is conducive to ensuring the integrity of the soil sample. In addition, the soil sample in the sampling tube 4 is divided into seven parts by the blocking structure, and each soil sample is blocked. The structure is isolated, so that even if the soil sample is squeezed when it is taken out of the sampling tube 4, the soil sample of the corresponding depth can be clearly taken out, avoiding the problem that the soil sample is squeezed when it is taken out of the sampling tube 4, resulting in local compression of the soil sample, and the corresponding depth of the soil cannot be determined, thereby affecting the subsequent analysis and evaluation results. The soil samples can be taken out in turn through the blocking structure composed of eight groups of first limiting plates 12 and telescopic cloths 13, that is, when each group of first limiting plates 12 and telescopic cloths 13 is moved to be flush with the upper outlet of the sampling tube 4, tools are used to remove and preserve the soil samples between two adjacent groups of first limiting plates 12 and telescopic cloths 13, so as to avoid the mixing of soil samples from different areas when taking out the soil samples, which affects the data analysis and evaluation results.

[0045] Example 2

[0046] On the basis of the above-mentioned embodiment 1, Figure 1 and Figure 8 As shown, it also includes a second limit plate 201; a plurality of limit groups are connected to the limit cylinder 10; each limit group is composed of three second limit plates 201 distributed in a circular array, and the second limit plates 201 on the same limit group are bolted to each other; each limit group is located between two adjacent partition components.

[0047] The second limiting plate 201 and the limiting cylinder 10 are arranged in a quick-release structure for limiting and cooperating in taking out the soil sample.

[0048] A blade is provided at the lower part of the second limiting plate 201 for breaking the soil.

[0049] During the sampling process, the second limiting plate 201 is used to break the soil sample and divide it into three groups. When taking out the soil sample, the staff uses tools to remove the bolts at the connection of the second limiting plate 201 of the same group, and then takes out the second limiting plates 201 one by one, that is, quickly taking out the soil sample to avoid being affected by the limiting tube 10 during the process of taking out the soil sample. The soil sample cannot be quickly divided and taken out by cutting, and sampling needs to be performed by scraping, resulting in a slow speed of taking out the soil sample. That is, through the above method, the soil sample can be taken out quickly while ensuring the integrity of the soil sample, which is more conducive to the subsequent analysis and evaluation of the soil sample. In addition, when the sampling tube 4 and the limiting tube 10 are inserted into the soil, the second limiting plate 201 is used to break the soil sample and divide it into three groups, which is convenient for the sampling tube 4 and the limiting tube 10 to be inserted into the soil for sampling.

[0050] A method for using a soil quality assessment device comprises the following steps:

[0051] Step 1: Place the sampling equipment in the area where soil assessment is required and then carry out sampling work;

[0052] Step 2: During the sampling process, the soil sample is protected by the cooperation of the first limiting plate 12 and the retractable cloth 13 to prevent leakage of the soil sample when the soil sample is taken out, resulting in loss of the soil sample;

[0053] Step 3: Take out the soil sample and seal it with the cooperation of the first limiting plate 12 and the telescopic cloth 13 to prevent the soil sample from being subjected to excessive squeezing force as a whole, which may cause the soil sample to be damaged;

[0054] Step 4: Encapsulate and preserve soil samples at different depths;

[0055] Step 5: Use detection instruments to analyze and evaluate the packaged soil samples. Preferably, it also includes a first soil detection box 18 and a second soil detection box 19; a first soil detection box 18 and a second soil detection box 19 are bolted to the two fixing frames 1; the first soil detection box 18 is provided with a pH detection probe, a conductivity detection probe and a moisture measurement probe; the second soil detection box 19 is provided with a heavy metal detection probe and a chemical composition detection probe; after taking out the soil sample from the sampling tube 4, the staff will place the taken out soil sample in the first soil detection box 18 and the second soil detection box 19 located on the left fixing frame 1, respectively, and the pH detection probes in the first soil detection box 18 and the second soil detection box 19 will be used to detect the soil sample. The soil samples are tested by using probes, conductivity detection probes, moisture determination probes, heavy metal detection probes and chemical composition detection probes, and then the probes transmit the detection data to the staff's mobile phone, so that the staff can evaluate the soil. After the spiral agitator 9 mixes the layered soil samples collected in the limiting cylinder 10 and transports them to the external collection device, the staff transfers part of the mixed soil samples in the external collection device, so that the soil samples in the external collection device are placed in the first soil detection box 18 and the second soil detection box 19 located on the right side fixed frame 1, respectively, and the mixed soil samples are detected and evaluated by the probes in the first soil detection box 18 and the second soil detection box 19.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention.
