[0002] Available silicon in soil refers to silicon in the soil that is soluble in water or weak acid solution and can be absorbed by plant growth. Available silicon is an essential element for plant growth and development. It can be directly absorbed and utilized by plant roots and is one of the trace beneficial elements in cultivated soil.

[0003] The national forestry standard LY / T1266-1999 "Determination of Available Silicon in Forest Soils" and the agricultural standard NY / T1121.15-2006 "Soil Testing Part 15: Determination of Available Silicon in Soil" both use the molybdenum blue spectrophotometric method to determine the available silicon content in soil. This method uses an extractant to soak the soil sample.

[0004] Ultrasonic soil extraction is a technology that uses ultrasound to assist in the extraction of chemical substances from soil. Ultrasonic extraction is mainly based on the cavitation effect and vibration of ultrasound, which stirs and shears the soil, accelerates the interaction and diffusion process between molecules, and promotes the extraction of substances. Compared with traditional extraction methods, ultrasonic extraction technology has the characteristics of high efficiency, rapidity, and high extraction rate, and is suitable for the detection and analysis of soil element content.

[0005] In the actual ultrasonic extraction process for effective silicon content detection in some soils, such as clay, agglomeration may occur. Soil agglomeration will affect the diffusion of the extractant in the soil, resulting in insufficient soil extraction, increasing the time required for the entire extraction process and reducing the extraction efficiency. Soil agglomeration leads to inadequate extraction process, which will affect the accuracy of the analysis results. Utility Model Content

[0035] This embodiment provides an ultrasonic extraction device for detecting the effective silicon content in soil, see Figure 1-Figure 5As shown, it includes a processing chamber 1, the upper part of the processing chamber 1 is connected to a feed pipe 21, the upper end of the feed pipe 21 is connected to a hopper 2, the upper part of the processing chamber 1 is installed with a first motor 11, the first motor 11 is connected to a rotating rod 111, the rotating rod 111 extends into the processing chamber 1, the inner wall of the processing chamber 1 is installed with a heating plate 12, the outer wall of the rotating rod 111 is connected with a blade 112, the processing chamber 1 is connected to the crushing device 4 through a guide pipe 3, the guide pipe 3 is installed with a first control valve 31, and the crushing device 4 includes a conical shell 4 1. A conical panel 42 is provided in the conical shell 41. The bottom of the conical shell 41 is connected to the upper part of the leaching chamber 5. A connecting rod 43 is connected to the lower part of the conical panel 42. The connecting rod 43 is transmission-connected to the second motor 44. The second motor 44 is installed on the upper part of the leaching chamber 5 through a fixing rod 441. An ultrasonic generator 51 is provided on the inner wall of the leaching chamber 5. The side walls of the leaching chamber 5 are respectively connected to a liquid inlet pipe 52 and a liquid outlet pipe 53. A second control valve 531 is installed on the liquid outlet pipe 53. A support leg 6 is provided at the bottom of the leaching chamber 5.

[0036] In the above embodiment, a feed pipe 21 is connected to the upper portion of the processing chamber 1, and a hopper 2 is connected to the upper end of the feed pipe 21. Soil to be extracted is placed in the hopper 2, and the soil enters the processing chamber 1 through the feed pipe 21. A first motor 11 is installed at the upper portion of the processing chamber 1. The first motor 11 is in transmission connection with a rotating rod 111 within the processing chamber 1. The outer wall of the rotating rod 111 is connected to blades 112. The first motor 11 drives the rotating rod 111 to drive the blades 112 to stir within the processing chamber 1. The collision of soil clumps with the blades 112 can break up the soil clumps and reduce their volume. Furthermore, a heating plate 12 is installed on the inner wall of the processing chamber 1. The heating plate 12 can increase the temperature within the processing chamber 1, evaporate the moisture within the soil, dry the soil, increase the brittleness of the soil, make the soil clumps easier to separate, and facilitate the crushing of the soil. The stirring of the soil by the blades 112 can heat the soil evenly within the processing chamber 1, improving the evaporation efficiency of the soil moisture. The processing chamber 1 is connected to the crushing device 4 through the guide pipe 3, and the guide pipe 3 is equipped with a first control valve 31. After the soil is processed in the processing chamber 1, the first control valve 31 is opened, and the soil passes through and enters the crushing device 4. A conical panel 42 is provided in the conical shell 41 of the crushing device 4. The top surface of the conical panel 42 is close to the bottom surface of the conical shell 41, so that there is a gap between the top surface of the conical panel 42 and the bottom surface of the conical shell 41, and a connecting rod 43 is connected to the lower part of the conical panel 42. The connecting rod 43 is connected to the second motor 44 for transmission. The second motor 44 drives the connecting rod 43 to drive the conical panel 42 to rotate, and the soil falls to the top surface of the conical panel 42 and the conical shell 4 1. The conical panel 42 rotates to further rub and crush the soil in the gap. The crushed soil falls along the conical top surface of the conical panel 42 and enters the extraction chamber 5 through the opening on the upper end surface of the extraction chamber 5. The second motor 44 is located below the conical panel 42. The crushed soil falls along the edge of the conical panel 42, preventing it from falling on the second motor 44 and affecting its operation. The soil particles become more broken and fine, allowing them to be more fully exposed to ultrasonic energy and the extractant, thereby improving the soil extraction effect. In other words, by pre-treating the soil through crushing, the soil extraction efficiency is improved, and the accuracy of the soil extraction analysis results is improved. In addition, the side walls of the extraction chamber 5 are connected to a liquid inlet pipe 52 and a liquid outlet pipe 53. The liquid outlet pipe 53 is equipped with a second control valve 531. The liquid inlet pipe 52 is used to inject the extracting liquid into the extraction chamber 5. Opening the second control valve 531 allows the soil extracting liquid to be discharged through the liquid outlet pipe 53 for relevant testing.

[0037] In one embodiment of the present application, see Figure 4 As shown, a crushing roller shaft 22 is installed in the hopper 2, and the crushing roller shaft 22 is transmission-connected to a third motor 23 on the outer wall of the hopper 2.

[0038] In the above embodiment, a pair of crushing rollers 22 are installed in the hopper 2, and the two crushing rollers 22 are respectively connected to the two third motors 23. The soil is placed between the two crushing rollers 22, so that the rotating crushing rollers 22 perform preliminary squeezing and crushing on the soil, thereby preventing the sampled soil from containing excessively large lumps that may cause the feed pipe 21 to be blocked, which is beneficial to improving the discharge smoothness of the feed pipe 21 and thereby improving the efficiency of soil extraction.

[0039] In one embodiment of the present application, see Figure 4 As shown, the side wall of the hopper 2 is connected to the top of the processing chamber 1 through a support plate 24.

[0040] In the above embodiment, the soil has a high density and a large deadweight. When the soil sample is placed in the hopper 2, the feed tube 21 is compressed and bent. The support plate 24 is used to support the hopper 2 and disperse the pressure of the hopper 2 on the feed tube 21, which is beneficial to improving the stability of the device.

[0041] In one embodiment of the present application, see Figure 1 As shown, an exhaust pipe 7 is connected to the top of the processing chamber 1.

[0042] In the above embodiment, when the heating plate 12 heats the soil sample in the processing chamber 1, the moisture in the soil will evaporate due to the heat, and the exhaust pipe 7 is used to discharge excess water vapor in the processing chamber 1, thereby reducing the humidity in the processing chamber 1 and improving the drying efficiency of the soil sample.

[0043] In one embodiment of the present application, see Figure 3 As shown, the connecting rod 43 is a telescopic rod.

[0044] In the above embodiment, the connecting rod 43 is a telescopic rod. By controlling the extension and shortening of the connecting rod 43, the gap between the conical inner wall of the conical shell 41 and the top of the conical panel 42 is changed. By changing the size of the gap, the particle size of the soil particles is controlled, which is used to control the variables of the soil extraction test. Later, the test data is compared, which is beneficial to improve the objectivity and accuracy of the data analysis.

[0045] In one embodiment of the present application, see Figure 1 As shown, a heat exchange tube 8 is installed in the extraction chamber 5 , and a water inlet 81 and a water outlet 82 of the heat exchange tube 8 are arranged on the outer wall of the extraction chamber 5 .

[0046] In the above embodiment, water of different temperatures is injected into the heat exchange tube 8, and the water undergoes heat exchange in the extraction chamber 5 through the heat exchange tube 8, thereby changing the temperature in the extraction chamber 5. When performing ultrasonic extraction testing of soil, temperature control is an important consideration. Temperature adjustment can not only affect the release rate of soluble substances in the soil, but may also affect the chemical composition of the extract, which is beneficial to improving the accuracy of the analytical results of ultrasonic extraction testing of soil.

[0047] In one embodiment of the present application, the outer wall of the leaching chamber 5 is covered with a thermal insulation layer.

[0048] In the above embodiment, during the ultrasonic extraction of soil, temperature fluctuations may lead to inconsistent results during the extraction process. The outer wall of the extraction chamber 5 is coated with an insulation layer, which is used to improve the temperature stability in the extraction chamber 5 and avoid temperature fluctuations, which is beneficial to improving the accuracy of the extraction data.

[0049] During the actual use of this application: the soil enters the processing chamber 1 through the feed pipe 21, the first motor 11 drives the rotating rod 111 to drive the blades 112 to stir in the processing chamber 1, and the soil lumps collide with the blades 112 to cause the soil lumps to break. A heating plate 12 is installed on the inner wall of the processing chamber 1 to increase the temperature in the processing chamber 1, so that the moisture in the soil evaporates and the soil dries, increasing the brittleness of the soil and making the soil lumps easier to separate. After the soil is processed in the processing chamber 1, the first control valve 31 is opened, and the soil passes through the crushing device 4. A conical panel 42 is disposed within the conical housing 41 of the crushing device 4. The top surface of the conical panel 42 is adjacent to the bottom surface of the conical housing 41, leaving a gap between the top and bottom surfaces of the conical housing 41. A connecting rod 43 is connected to the bottom of the conical panel 42, which is in transmission connection with a second motor 44. The second motor 44 drives the connecting rod 43 to rotate the conical panel 42, causing the soil to fall into the gap between the top and bottom surfaces of the conical housing 41. The rotation of the conical panel 42 further causes friction and crushing of the soil in the gap, resulting in finer and more pulverized soil particles. The crushed soil eventually enters the extraction chamber 5. Extraction liquid is added to the extraction chamber 5 through the liquid inlet pipe 52. The ultrasonic generator 51 is activated to ultrasonically extract the soil in the extract liquid. The second control valve 531 is opened to discharge the soil extract liquid through the liquid outlet pipe 53 for relevant testing.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
