Description

Technical Field

[0001] The present application relates to the technical field of soil treatment, and in particular to a soil treatment device used before soil trace element analysis. Background Art

[0002] Soil trace element analysis refers to the process of measuring and analyzing chemical elements in extremely low concentrations in the soil. Although these elements are present in small amounts, they play a vital role in the growth and development of plants. Common soil trace elements include boron, manganese, copper, zinc, iron, molybdenum, etc. Trace elements participate in a variety of physiological processes in plants, such as enzymatic reactions, photosynthesis, and material transport. They are indispensable catalysts or components of these processes3. For example, iron is an important element for chlorophyll synthesis, zinc participates in plant growth regulation, and manganese affects photosynthesis and nitrogen fixation.

[0003] Soil trace element detectors are the main tools for soil trace element analysis. They can detect nitrogen, phosphorus, potassium, organic matter, trace elements, pH value, moisture, salt content and other items in the soil2. These instruments use highly intelligent soil testing formula detection technology. Through the detection data, scientific fertilization plans can be formulated to meet the nutritional needs of crops, while reducing the burden on the soil, reducing fertilization costs, and improving crop yields and quality.

DETAILED DESCRIPTION

[0032] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0033] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0034] Figure 1 This is a schematic diagram of the structure of a soil treatment device before soil trace element analysis provided in an embodiment of the present application. Figure 1 As shown, the soil treatment device for soil trace element analysis comprises a screening component 100 and a reaction component 200. The screening component 100 mainly screens the soil to remove soil with large particle sizes, and the reaction component 200 is used to receive the soil screened by the screening component 100 and digest it to obtain soil that can be used for soil trace element analysis.

[0035] like Figure 2 and Figure 3 As shown, the screening assembly 100 includes an outer cylinder 101, an inner cylinder 102, a driving assembly 103 and a feed hopper 104. One end of the outer cylinder 101 is open, and the feed hopper 104 is arranged at the open end of the outer cylinder 101. A discharge pipe 105 is arranged on the outer cylinder 101, and the inner cylinder 102 is arranged inside the outer cylinder. The driving assembly 103 is fixed on the outer cylinder 101, and the driving assembly 103 is connected to the inner cylinder 102 to drive the inner cylinder 102 to rotate in the outer cylinder 101. The inner cylinder 102 is provided with a plurality of first sieve holes 1021 and second sieve holes 1022. The aperture of the second sieve holes 1022 is larger than the aperture of the first sieve holes 1021. When the inner cylinder 102 is in the initial state, the first sieve holes 1021 are located below the second sieve holes 1022.

[0036] In this embodiment, the working principle of the screening assembly 100 is as follows:

[0037] The initial state of the inner cylinder 102 is Figure 3The state shown, in which the soil to be treated is fed into the inner cylinder 102 through the feed hopper 106. The feeding method can be manual feeding or feeding using an existing feeding structure, which is not elaborated in detail in this embodiment. After a batch of soil to be treated is fed into the inner cylinder 102, the inner cylinder 102 is driven to rotate back and forth by the drive assembly 103, that is, it rotates clockwise and counterclockwise periodically, and the amplitude of each rotation should ensure that the soil to be treated in the inner cylinder 102 will not leak out from the second sieve hole 1022, so that the soil smaller than the aperture of the first sieve hole 1021 falls from the first sieve hole 1021 into the interlayer 106 between the outer cylinder 101 and the inner cylinder 102, and the sieved soil is transported to the reaction component 200 through the discharge pipe 105. After the screening is completed, the driving assembly 103 can be adjusted to drive the inner cylinder 102 to rotate 360 ​​degrees, so that the soil with large particle size can pass through the second sieve hole 1022 and then be discharged from the discharge pipe 105.

[0038] In some embodiments, Figure 4 As shown, the soil treatment device before soil trace element analysis also includes a support frame 300, which includes a support rod 301, a rotating motor 302 and a connecting rod 303. The rotating motor 302 is installed at the upper end of the support rod 301, and the rotating motor 302 is connected to the connecting rod 303. The screening component 100 is installed on the connecting rod 303.

[0039] In this embodiment, when screening small-particle soil, the screening component 100 is tiltedly arranged at the upper end of the reaction component 200, and the inclination direction of the screening component 100 is determined according to the setting position of the discharge pipe 105, so as to ensure that the soil in the interlayer 106 can be smoothly discharged from the discharge pipe 105. When the screening of small-particle soil is completed and large-particle soil needs to be discharged, the connecting rod 303 is driven to rotate by the rotating motor 302, so that the screening component 100 rotates accordingly, and is displaced to the receiving area of ​​large-particle soil. By adjusting the working mode of the driving component 103, the large-particle soil is discharged through the discharge pipe 105.

[0040] In some embodiments, Figure 3 As shown, the driving assembly 103 includes a servo motor 1031, a first sprocket 1032, a chain 1033 and a second sprocket 1034; wherein the output end of the servo motor 1031 is connected to the first sprocket 1032, the first sprocket 1032 is connected to the second sprocket 1034 through the chain 1033, and the second sprocket 1034 is arranged on the outer side of the inner cylinder 102.

[0041] In this embodiment, the servo motor 1031 periodically rotates forward and reverse, and drives the second sprocket 1034 arranged on the outside of the inner cylinder 102 to rotate through the first sprocket 1032 and the chain 1033, so that the inner cylinder 102 rotates, and the soil screening operation inside the inner cylinder 102 is realized through the rotating inner cylinder 102.

[0042] In some embodiments, Figure 1 As shown, the screening assembly 100 further includes a fan 107 , which is disposed at the upper end of the open end of the outer cylinder 101 .

[0043] In this embodiment, the function of the fan 107 is to slowly deliver hot air into the inner cylinder 102 facing the soil that has not been completely dried, so as to dry the soil. The fan 107 can be started before or during the soil screening process to provide a certain temperature environment during the soil screening to ensure the screening effect. It should be noted that the wind force of the fan 107 should not be too large to avoid blowing large particles of soil out of the second sieve hole 1022 and affecting the screening process.

[0044] In some embodiments, a discharge valve 108 is disposed on the discharge pipe 105 , and the discharge of the screening component 100 is controlled by the discharge valve 108 .

[0045] like Figure 5 and Figure 6 As shown, the reaction component 200 includes a frame 201, a first transverse plate 202, a second transverse plate 203, a third transverse plate 204 and a fourth transverse plate 205. The first transverse plate 202, the second transverse plate 203, the third transverse plate 204 and the fourth transverse plate 205 are arranged on the frame 201 from top to bottom, wherein the first transverse plate 202 and the fourth transverse plate 205 are fixedly arranged at the top and bottom of the frame 201, and the second transverse plate 203 and the third transverse plate 204 are rotatably arranged in the middle of the frame 201. A feed channel 2021 is arranged on the first transverse plate 202, and the feed channel 2021 corresponds to the discharge channel 105 on the outer cylinder 101. A first reaction container 206 is arranged on the second transverse plate 203, and a second reaction container 207 is arranged on the third transverse plate 204. An outflow pipe 2061 is arranged at the bottom of the first reaction container 206, and an outflow valve 2062 is arranged on the outflow pipe 2061.

[0046] In this embodiment, the working principle of the reaction component 200 is as follows:

[0047] The soil from the screening component 100 enters the first reaction container 206 through the feed channel 2021. There are multiple first reaction containers 206. Since the second transverse plate 203 is rotatable, when receiving the material, the second transverse plate 203 can be rotated to make the first reaction container 206 located below the feed channel 2021. After one first reaction container 206 has received the material, the second transverse plate 203 is rotated again to make another first reaction container 206 come to the bottom of the feed channel 2021 for receiving the material. The outflow valve 2062 in the first reaction container 206 is in a closed state during the material receiving process and the reaction process. After a batch of soil is received, the first reaction container 206 begins to soak and dissolve the soil. The first reaction container 206 has an opening at the top, and a proper amount of pure water can be directly added. After the pure water is added to each first reaction container 206, the second horizontal plate 203 is rotated at a set speed to achieve a stirring operation of the soil and pure water in the first reaction container 206 to accelerate the dissolution rate. After the dissolution operation is completed, the third horizontal plate 204 is rotated so that the second reaction container 207 is directly opposite to the first reaction container 206, and then the outflow valve 2062 is opened. Under the action of gravity, the soil solution / slurry obtained in the first reaction container 206 enters the second reaction container 207. The second reaction container 207 also has an opening at the top, and an acidic system solution can be added by configuring a pipeline or other means to digest the soil solution / slurry. After the addition of the acidic system solution is completed, the third horizontal plate 204 is rotated at a set speed to stir the reactants in the second reaction container 207 to speed up the digestion treatment efficiency. After the treatment is completed, the first reaction container 206 and the second reaction container 207 are removed. The reactants obtained in the second reaction container 207 can be taken out and stored or the second reaction container 207 can be directly used as a storage container to clean the first reaction container 206; then the first reaction container 206 and the second reaction container 207 are reinstalled on the second horizontal plate 203 and the third horizontal plate 204. The first reaction container 206 and the second reaction container 207 are assembled in the same manner as the second horizontal plate 203 and the third horizontal plate 204. Taking the first reaction container 206 as an example, a through hole is set on the second horizontal plate 203, and a clamp is set on the through hole. The bottleneck or body of the first reaction container 206 is fixed by the clamp to fix the first reaction container 206. When it is necessary to take it out, the clamp can be released.

[0048] In some embodiments, Figure 6 As shown, a vibration motor 208 is disposed at the lower end of the first horizontal plate 202 , and a screen 2022 is disposed in the feed channel 2021 .

[0049] In this embodiment, the first horizontal plate 202 also serves as a secondary screening function. According to actual needs, if finer particles of soil are required, if the diameter of the first sieve hole 1021 in the inner cylinder 102 is changed, the change amount is large. Therefore, it is considered to add a screen 2022 to the feed channel 2021. In the face of different needs, the corresponding screen 2022 can be directly selected, and the overall equipment is less changed. In addition, the vibration motor 208 is configured and the vibration screening method is adopted to avoid the problem of blockage of the screen 2023, and at the same time, the screening efficiency of the soil can be guaranteed.

[0050] In some embodiments, Figure 6 As shown, a first driving assembly 209 is disposed on the frame 201, and the first driving assembly 209 is used to drive the second transverse plate 203 to rotate. The first driving assembly 209 includes at least one first bracket 2091, and a first electric drive wheel 2092 is disposed on the first bracket 2091. The first electric drive wheel 2092 is disposed below the second transverse plate 203 and contacts the second transverse plate 203.

[0051] The present embodiment provides a method for driving the second transverse plate 203 to rotate. The second transverse plate 203 can be rotatably set on the frame 201 through a bearing seat. Considering the compactness of the overall structure, multiple first electric drive wheels 2092 are set. The first electric drive wheel 2092 can be a wheel body that can be rotated by a motor. When the first electric drive wheel 2092 rotates, it drives the second transverse plate 203 to rotate at the same time.

[0052] In some embodiments, Figure 6 As shown, a second drive assembly 210 is provided on the frame 201, and the second drive assembly 210 is used to drive the third transverse plate 204 to rotate. The second drive assembly 210 includes at least one second bracket 2101, and a second electric drive wheel 2102 is provided on the second bracket 201. The second electric drive wheel 2102 is arranged below the third transverse plate 204 and contacts the third transverse plate 204. The structural principle of the second drive assembly 210 is consistent with the structural principle of the first drive assembly 209, so it is not repeated here.
