Description

Technical Field

[0001] This invention relates to the field of spectral soil analysis, and more specifically, to a soil composition analysis system and apparatus based on spectral technology. Background Technology

[0002] The properties of soil in absorbing and reflecting light waves are closely related to the soil's composition, structure, and texture. The reflectance and absorptivity of soil samples within a specific wavelength range can directly reflect the soil's biochemical characteristics. By performing spectral analysis on soil samples, a wealth of information about the soil's physical, chemical, and biological characteristics can be obtained, making it an important tool in the field of soil science research.

[0003] Traditional soil composition analysis systems require soil samples to be extracted and sent to the laboratory for analysis, which is time-consuming. Because of this time-consuming process, soil samples may be affected by the environment or improperly preserved, which can lead to errors in the soil analysis results.

[0004] For example, the specification of the "Intelligent Analysis System and Analytical Device for Soil Composition Content Detection" disclosed in Chinese Invention Patent (Application No.: CN202110497684.0) states that: Currently, existing soil composition detection equipment requires sending the soil to be tested to a laboratory for testing, which is cumbersome, inefficient, and costly; at the same time, because soil composition is very complex, the content of soil texture, moisture, organic matter, iron oxide, etc., will affect the spectral characteristics of the soil, and ex-situ detection of soil samples may result in soil degeneration, affecting the test results; the above patent can corroborate the defects of the existing technology.

[0005] Therefore, we have made improvements to this and proposed a soil composition analysis system and device based on spectral technology. Summary of the Invention

[0006] The purpose of this invention is to address the issue that in existing traditional soil composition analysis systems, soil samples are extracted first and then sent to the laboratory for analysis. However, the results can be erroneous due to environmental factors or improper storage of the soil samples.

[0007] To achieve the above-mentioned objectives, the present invention provides the following soil composition analysis system and apparatus based on spectral technology to improve the aforementioned problems.

[0008] The application is as follows:

[0009] A soil composition analysis system based on spectral technology, comprising:

[0010] Light source: Used to emit light of a specific wavelength;

[0011] Spectral detection module: Employs a photodiode array to precisely measure the spectral reflectance and absorbance of soil samples at different wavelengths, thereby acquiring spectral information of the soil samples;

[0012] Data analysis and processing module: used to process the measured spectral data and infer the composition of the soil based on the pre-established model;

[0013] User interface: Used to display soil composition analysis results.

[0014] As a preferred technical solution of this application, the light source is a laser diode, and its wavelength range can be selected by the staff on-site according to the needs of soil composition analysis.

[0015] As a preferred technical solution of this application, the spectral detection module includes a detection device for detecting soil samples and providing data to the spectral detection module. The spectral detection module achieves continuous measurement of the full spectrum and specific wavelength range of the soil sample through multi-channel measurement.

[0016] As a preferred technical solution of this application, the data analysis and processing module can accurately infer the component content in the soil by comparing it with the spectral data of the soil sample and using model fitting.

[0017] As a preferred technical solution of this application, the data analysis and processing module includes a data integration unit, which integrates data from environmental monitoring stations in various regions.

[0018] As a preferred technical solution of this application, the user interface includes a human-computer interaction unit, which allows users to select and adjust different data processing methods, model parameters or result display methods as needed.

[0019] A soil composition analysis device based on spectral technology includes a detection component. A fixed handle is fixedly connected to the top of the detection component. Positioning rings are fixedly connected to both sides of the front and back of the fixed handle. An L-shaped support column is movably connected to the outside of the positioning ring. A soil cleaning and loosening component is fixedly connected to the bottom of the outside of the positioning ring. The soil cleaning and loosening component includes a first rotating component, which is located on the front of the fixed handle.

[0020] As a preferred technical solution of this application, the detection component includes a detection handle, a control button fixedly connected to one side of the detection handle, a power supply movably connected to the bottom of the detection handle, a detection host fixedly connected to the top of the detection handle, a spectral emission end fixedly connected to one side of the detection host, a glass plate fixedly connected to one side of the detection host, a U-shaped fixing plate fixedly connected to one side of the bottom of the detection host, an electric telescopic sleeve fixedly connected to one side of the U-shaped fixing plate, and an electric telescopic inner tube movably connected to the inner side of the electric telescopic sleeve.

[0021] As a preferred technical solution of this application, the fixed handle includes a handle body, a first fixing block is movably engaged with the top of one side of the handle body, a prototype handle is fixedly connected to one side of the first fixing block, a positioning strip is fixedly connected to the other side of the first fixing block, and a rubber strip is fixedly connected to the bottom of the positioning strip.

[0022] As a preferred technical solution of this application, the cleaning and loosening component also includes a conversion component, and a second rotating component is fixedly connected to one side of the bottom of the conversion component, and the outer side of the second rotating component is movably engaged with the first rotating component.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] In the scheme of this application:

[0025] 1. In order to solve the problem that soil samples sent to the laboratory are affected by the environment or improperly stored, which can lead to errors in the results, the soil composition analysis system is built into the soil composition analysis device. Compared with traditional soil composition analysis methods, this system can perform rapid and accurate soil composition analysis in the field without having to bring the samples back to the laboratory for processing, saving time and human resources.

[0026] 2. To address the issue of inaccurate test results caused by the inability of the testing end to stably adhere to the ground during testing in existing portable soil testing equipment, a positioning ring and a fixing handle are designed. The positioning ring connects the fixing handle, the soil cleaning and loosening component, and the L-shaped support column. The fixing handle serves as a support rod at the top of the positioning ring, and the soil cleaning and loosening component serves as a support rod at the bottom of the positioning ring. Together with the L-shaped support column, this design ensures that the testing end of the testing component is parallel to the ground when testing soil composition, thus providing a fixing function.

[0027] 3. The first and second rotating components of this application are configured such that when the electric telescopic sleeve and the electric telescopic inner tube are fully retracted, the first and second rotating components are on the same horizontal plane as the L-shaped support column, which assists the L-shaped support column in supporting the entire detection component and can play an auxiliary role in fixing the equipment during detection.

[0028] 4. By setting the first and second rotating components, when the electric telescopic sleeve and the electric telescopic inner tube are pushed out and the other side of the first and second rotating components are on the same plane as one side of the detection component, the first and second rotating components can clean the soil attached to the detection port of the equipment, which solves the problem in the prior art that the soil attached to the detection port after soil detection interferes with the next detection.

[0029] 5. In order to solve the problem of inaccurate soil composition analysis caused by high surface moisture content after rain and snow in the prior art, this application sets up a first rotating component and a second rotating component. When the electric telescopic sleeve and the electric telescopic inner tube are pushed out and the other side of the first rotating component and the second rotating component are away from the detection component, the first rotating component and the second rotating component rotate, thereby loosening the soil at the detection position, facilitating the detection of deeper soil and ensuring the accuracy of the detection results;

[0030] 6. With the fixed handle, staff can lift the handle body to use it as a handle to pick up the device, avoiding accidental touches of control buttons when directly detecting the handle, and preventing empty or useless data from being left in the system;

[0031] 7. With the fixed handle, the first fixed block, prototype handle, positioning strip and rubber strip work together to clean the dust on the surface of the equipment. After work, the staff can directly clean the surface of the equipment without the need to prepare additional cleaning materials, thus saving costs. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0049] As in the background art, traditional soil composition analysis systems first extract soil samples and then send them to the laboratory for analysis. Soil samples may be affected by the environment or improperly preserved, which can lead to errors in the results.

[0050] To address this technical problem, the present invention provides a soil composition analysis system and apparatus based on spectral technology, which is applied to spectral soil analysis.

[0056] The soil composition analysis system based on spectral technology provided by this invention, by integrating a soil composition analysis system into a soil composition analysis device, allows for rapid and accurate soil composition analysis in the field compared to traditional soil composition analysis methods. This eliminates the need to bring samples back to the laboratory for processing, saving time and human resources.

[0057] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0058] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0059] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0060] Example 1

[0061] Please refer to Figure 1 A soil composition analysis system based on spectral technology, whose light source uses laser diodes and whose wavelength range can be selected by staff on-site according to the needs of soil composition analysis.

[0062] Please refer to Figure 1A soil composition analysis system based on spectral technology is disclosed.

The spectral detection module achieves continuous measurement of the full spectrum and specific wavelength range of soil samples through multi-channel measurement. By measuring the spectral information of soil samples at different wavelengths through the spectral detection device, the system can simultaneously analyze multiple soil composition parameters, such as water content, organic matter content, nitrogen, phosphorus, potassium and other element content, providing comprehensive soil analysis results.

[0063] Furthermore, such as Figure 1 The data analysis and processing module can accurately infer the content of soil components by comparing the spectral data with the soil sample and using model fitting. The data analysis and processing module includes a data integration unit, which integrates data from environmental monitoring stations in various regions, integrates local environmental data, comprehensively analyzes soil components, and provides more comprehensive soil component analysis results and decision support.

[0064] Furthermore, such as Figure 1 The user interface includes a human-computer interaction unit, allowing users to select and adjust different data processing methods, model parameters, or result display methods as needed, thereby optimizing the user experience.

[0065] Example 2

[0066] Please refer to Figure 1 and Figure 3 A soil composition analysis device based on spectral technology includes a detection component 1. A fixed handle 2 is fixedly connected to the top of the detection component 1. Positioning rings 3 are fixedly connected to both sides of the front and back of the fixed handle 2. An L-shaped support column 5 is movably connected to the outside of the positioning ring 3. A soil cleaning and loosening component 4 is fixedly connected to the bottom of the outside of the positioning ring 3. The soil cleaning and loosening component 4 includes a first rotating component 402, which is located on the front of the fixed handle 2.

[0067] The soil composition analysis device based on spectral technology provided by this invention includes a detection component 1 suitable for detecting soil components; a fixed handle 2 that can be used as a handle for picking up the handle body 201, and also used for cleaning dust from the surface of the device through the cooperation of the first fixing block 202, the prototype handle 203, the positioning strip 204, and the rubber strip 205; a positioning ring 3 for connecting the fixed handle 2, the cleaning and loosening component 4, and the L-shaped support column 5; and the extension of the electric telescopic sleeve 108 and the electric telescopic inner tube 109 to move the other side of the first rotating component 402 and the second rotating component 403 away from the detection component. When the first rotating component 402 and the second rotating component 403 rotate on one side of component 1, they loosen the soil at the detection position. When the electric telescopic sleeve 108 and the electric telescopic inner tube 109 are fully retracted, the first rotating component 402 and the second rotating component 403 provide certain support for the detection chamber equipment. When the electric telescopic sleeve 108 and the electric telescopic inner tube 109 are extended and the other side of the first rotating component 402 and the second rotating component 403 are on the same plane as one side of the detection component 1, the first rotating component 402 and the second rotating component 403 can clean the soil attached to the detection port of the equipment.

[0068] Example 3

[0069] The soil composition analysis device based on spectral technology provided in Example 2 has been further optimized, specifically, as follows: Figure 2 As shown, the detection assembly 1 includes a detection handle 101, a control button 102 fixedly connected to one side of the detection handle 101, a power supply 103 movably connected to the bottom of the detection handle 101, a detection host 104 fixedly connected to the top of the detection handle 101, a spectral emission end 105 fixedly connected to one side of the detection host 104, a glass plate 106 fixedly connected to one side of the detection host 104, a U-shaped fixing plate 107 fixedly connected to one side of the bottom of the detection host 104, an electric telescopic sleeve 108 fixedly connected to one side of the U-shaped fixing plate 107, and an electric telescopic inner tube 109 movably connected to the inner side of the electric telescopic sleeve 108.

[0070] When testing soil composition, the operator holds the testing handle 101, then holds the testing host 104 perpendicular to the soil surface, then brings the glass plate 106 into contact with the soil surface, and then presses the control button 102 to start the equipment to test the soil composition at the bottom of the glass plate 106.

[0071] Furthermore, such as Figure 2As shown, the fixing hole at the top of the electric telescopic inner tube 109 cooperates with the positioning ring 3 to ensure the stability of the connection between the detection component 1 and the positioning ring 3. The other side of the detection host 104 is equipped with a data display, which is used to display the soil composition analysis results. The glass plate 106 completely covers the space where the spectral emission end 105 is located. The spectral emission end 105 analyzes the soil composition through spectral technology. The glass plate 106 covers it to protect the spectral emission end 105. The detection component 1 is the detection device of the spectral detection module. During the soil composition detection process, the spectral information of the spectral detection module comes from the data extracted by the spectral emission end 105.

[0072] Example 4

[0073] The soil composition analysis device based on spectral technology provided in Example 2 or 3 is further optimized, specifically, as follows: Figure 4 As shown, the fixed handle 2 includes a handle body 201. During the movement of the equipment, the operator can lift the handle body 201 to facilitate the movement of the equipment. A first fixing block 202 is movably engaged at the top of one side of the handle body 201. A prototype handle 203 is fixedly connected to one side of the first fixing block 202. A positioning strip 204 is fixedly connected to the other side of the first fixing block 202. A rubber strip 205 is fixedly connected to the bottom of the positioning strip 204. The first fixing block 202, the prototype handle 203, the positioning strip 204, and the rubber strip 205 can be removed to clean the dust on the surface of the equipment.

[0074] Furthermore, such as Figure 4 As shown, a fixing groove is provided on one side of the top of the handle body 201. The size of the fixing groove of the handle body 201 matches the positioning strip 204 and the rubber strip 205 to ensure that the positioning strip 204 and the rubber strip 205 can be completely stored in the fixing groove on one side of the top of the handle body 201, and can be used for cleaning equipment when needed.

[0075] Example 5

[0076] Furthermore, such as Figure 4 As shown, the cleaning and loosening component 4 includes a conversion component 401. The length of the conversion component 401, the length of the fixed handle 2, and the length of the L-shaped support column 5 are the same. When the fixed handle 2, the cleaning and loosening component 4, and the L-shaped support column 5 are used together as a base, the height of the four corners is uniform to ensure the stability when the detection component 1 is fixed. A second rotating component 403 is fixedly connected to one side of the bottom of the conversion component 401. The outer side of the second rotating component 403 is movably engaged with the first rotating component 402.

[0077] Furthermore, such as Figure 4As shown, the conversion assembly 401 includes a positioning rod 4011. A second fixing block 4012 is fixedly connected to one side of the top of the positioning rod 4011. A first motor 4013 is fixedly connected to the top of the second fixing block 4012. The second fixing block 4012 is used to fix the first motor 4013. The output shaft of the first motor 4013 is connected to a first gear 4014 for transmission. The first motor 4013 drives the first gear 4014 to rotate. A bearing 4015 is fixedly sleeved on one side of the positioning rod 4011. A positioning shaft 4016 is fixedly connected to the inner side of 5. The connection between the positioning shaft 4016 and the bearing 4015 is the inner wall of the bearing 4015, and the connection between the bearing 4015 and the positioning rod 4011 is the outer wall of the bearing 4015. When the positioning shaft 4016 and the second gear 4017 rotate synchronously, the inner wall of the bearing 4015 rotates while the outer wall remains stationary, that is, the positioning rod 4011 remains horizontal. The second gear 4017 is fixedly connected to one side of the positioning shaft 4016, and a third fixing block 4 is fixedly connected to one side of the second gear 4017. 019, when the first gear 4014 rotates under the operation of the first motor 4013, it drives the second gear 4017 to rotate. The second gear 4017 is fixedly connected to the third fixed block 4019, so they can rotate synchronously. The bottom of the third fixed block 4019 is provided with a T-shaped groove 4018, and the top of the third fixed block 4019 is movably engaged with a fourth fixed block 40110. One side of the fourth fixed block 40110 is fixedly connected with a first T-shaped positioning block 40111, and the bottom of the fourth fixed block 40110 is fixed. The first rotating component 402 and the second rotating component 403 are fixedly connected to a second T-shaped positioning block 40112. When the first rotating component 402 and the second rotating component 403 are working, the fourth fixing block 40110, the first T-shaped positioning block 40111 and the second T-shaped positioning block 40112 are taken out along the concave groove on the top of the third fixing block 4019. Then, the second T-shaped positioning block 40112 is turned to the other side, and the first T-shaped positioning block 40111 is inserted into the T-shaped groove 4018, thereby limiting the first rotating component 402 and the second rotating component 403.

[0078] Furthermore, such as Figure 4As shown, one side of the first gear 4014 and one side of the second gear 4017 are on the same plane. The outer teeth of the first gear 4014 mesh with the outer teeth of the second gear 4017. The first motor 4013 drives the first gear 4014 to rotate. Due to the meshing relationship, the first gear 4014 can drive the second gear 4017 to rotate. A combined circular hole is provided on the front of the positioning rod 4011. The size of the circular hole of the positioning rod 4011 matches the size of the positioning ring 3. The cleaning and loosening component 4 passes through the positioning rod 4011. The circular hole is fixedly connected to the positioning ring 3, so that the top of the third fixing block 4019 is fitted with a concave groove. The concave groove on the top of the third fixing block 4019 matches the size of the second T-shaped positioning block 40112, ensuring that the fourth fixing block 40110, the first T-shaped positioning block 40111 and the second T-shaped positioning block 40112 can be removed along the concave groove on the top of the third fixing block 4019. The size of the first T-shaped positioning block 40111 matches the size of the T-shaped groove 4018. The top of the electric telescopic inner tube 109 is provided with a fixing hole.

[0079] Furthermore, such as Figure 8 As shown, the first rotating assembly 402 includes a rotating block 4021, with a positioning rod 4022 fixedly connected to the top and bottom of the rotating block 4021. A third gear 4023 is fixedly connected to the top of the outer side of the rotating block 4021. A circular hole is provided on the top of the rotating block 4021, and a positioning rod and a first cleaning cloth 4024 are fixedly connected to one side of the rotating block 4021. The second rotating assembly 403 includes a fixing plate 4031, with a rotating... The rotating block 4032 has a positioning block 4033 fixedly connected to its bottom. The positioning block 4033 has a fifth fixing block 4034 fixedly connected to its front. The fifth fixing block 4034 has a second motor 4035 fixedly connected to its front. The output shaft of the second motor 4035 is connected to the fourth gear 4036 for transmission. The positioning block 4033 has a rotating rod 4039 fixedly connected to its bottom. The positioning block 4033, located in the middle of the second rotating assembly 403, has a positioning arc groove 4037 on its top.

[0080] The first rotating component 402 and the second rotating component 403 support the surface of the soil being tested, preventing deviations in the soil composition results from the detection component 1 due to the operator holding the device during testing. The second motor 4035 then drives the fourth gear 4036 to rotate, which in turn drives the third gear 4023 to rotate. The third gear 4023 then rotates along the rotating rod 4039. The positioning groove 4037 and the positioning rod 4022 limit the angle between the rotating block 4021 and the positioning block 4033 to 45 degrees. The relationship between the side of the soil cleaning component 4 and the side of the detection component 1 is controlled by the telescopic control between the electric telescopic sleeve 108 and the electric telescopic inner tube 109. When the electric telescopic sleeve 108 and the electric telescopic inner tube 109 are fully retracted, the first rotating component 402 and the second rotating component 403 support the detection component 1.

[0081] When the electric telescopic sleeve 108 and the electric telescopic inner tube 109 are extended and the other side of the first rotating component 402 and the second rotating component 403 are on the same plane as one side of the detection component 1, the operation of the first motor 4013 can drive the first rotating component 402 and the second rotating component 403 to rotate, and the glass plate 106 is cleaned by the first cleaning cloth 4024 and the second cleaning cloth 4038 on the other side of the first rotating component 402 and the second rotating component 403.

[0082] When the electric telescopic sleeve 108 and the electric telescopic inner tube 109 are extended to the side of the first rotating component 402 and the second rotating component 403 away from the detection component 1, the second motor 4035 drives the fourth gear 4036 to rotate, which in turn drives the third gear 4023 to rotate. Then the third gear 4023 rotates along the rotating rod 4039. The positioning arc groove 4037 and the positioning rod 4022 limit the angle between the rotating block 4021 and the positioning block 4033 to 45 degrees. The first motor 4013 drives the first rotating component 402 and the second rotating component 403 to rotate and loosen the soil.

[0083] Furthermore, such as Figure 4As shown, the circular hole at the top of the rotating block 4021 matches the dimensions of the rotating rod 4039. The rotating rod 4039 is movably fitted inside the circular hole at the top of the rotating block 4021, allowing the rotating block 4021 to rotate along the rotating rod 4039. The dimensions of the positioning arc groove 4037 match the dimensions of the positioning rod 4022. When the rotating block 4021 rotates along the rotating rod 4039, the positioning rod 4022 moves within the positioning arc groove 4037. When the positioning rod 4022 is at the center of the positioning arc groove 4037, the rotating block 4021 and the positioning block 4033 are on the same horizontal line. When the positioning rod 4022 is at either end of the inner side of the positioning arc groove 4037, the included angle between the rotating block 4021 and the positioning block 4033 is forty-five degrees. The distance between the rotating blocks 4021 is matched with the size of the positioning block 4033. There is a positioning block 4033 between two adjacent rotating blocks 4021. The distance between the positioning blocks 4033 is matched with the size of the rotating blocks 4021. There is a rotating block 4021 between two adjacent positioning blocks 4033. The top of the fourth gear 4036 is on the same plane as the top of the third gear 4023. When the second motor 4035 is running, the rotation of the fourth gear 4036 can drive the rotation of the third gear 4023. The outer teeth of the fourth gear 4036 mesh with the outer teeth of the third gear 4023. The second motor 4035 can drive the fourth gear 4036 to rotate, which in turn drives the third gear 4023 to rotate.

[0084] The usage process of the soil composition analysis system and device based on spectral technology provided by this invention is as follows:

[0085] When testing soil composition, the operator holds the testing handle 101, then holds the main testing unit 104 perpendicular to the soil surface, and then contacts the glass plate 106 with the soil surface. Pressing the control button 102 starts the equipment to test the soil composition at the bottom of the glass plate 106. During equipment movement, the operator can easily remove the handle body 201 for convenient equipment movement. The first fixing block 202, prototype handle 203, positioning strip 204, and rubber strip 205 can be removed to clean the surface of the equipment. The first motor 4013 drives the first gear 4014 to rotate, which in turn drives the second gear 4017 to rotate due to the meshing of the teeth. Then, the third fixing block 4019 rotates synchronously. When the first rotating component 402 and the second rotating component 403 are working, the fourth fixing block 40110, the first T-shaped positioning block 40111, and the second T-shaped positioning block 40112 are removed along the fixing groove on the top of the third fixing block 4019. Then, the second T-shaped positioning block 40112 is turned to the other side, and the first T-shaped positioning block 40111 is inserted into the T-shaped groove 4018. This limits the first rotating component 402 and the second rotating component 403. The surface of the soil being tested by the first rotating component 402 and the second rotating component 403 supports the detection component 1, preventing the detection surface from not making good contact with the soil due to the operator holding the equipment during the detection process. The soil composition detected by the detection component 1 is deviated due to the soil condition. This is then addressed by the second motor 4035, which drives the fourth gear 4036 to rotate, which in turn drives the third gear 4023. The third gear 4023 then rotates along the rotating rod 4039. The positioning groove 4037 and the positioning rod 4022 limit the angle between the rotating block 4021 and the positioning block 4033 to 45 degrees. The relationship between the side of the soil cleaning and loosening component 4 and the side of the detection component 1 is controlled by the telescopic control between the electric telescopic sleeve 108 and the electric telescopic inner tube 109. When the electric telescopic sleeve 108 and the electric telescopic inner tube 109 are fully retracted, the first rotating component 402 and the second rotating component 403 support the detection component 1. When the telescopic sleeve 108 and the electric telescopic inner tube 109 are extended, and the other side of the first rotating assembly 402 and the second rotating assembly 403 are on the same plane as one side of the detection assembly 1, the operation of the first motor 4013 can drive the first rotating assembly 402 and the second rotating assembly 403 to rotate. The first cleaning cloth 4024 and the second cleaning cloth 4038 on the other side of the first rotating assembly 402 and the second rotating assembly 403 clean the glass plate 106. When the electric telescopic sleeve 108 and the electric telescopic inner tube 109 are extended, and the other side of the first rotating assembly 402 and the second rotating assembly 403 is away from the side of the detection assembly 1, the operation of the second motor 4035 drives the fourth gear 4036 to rotate, which in turn drives the third gear 4023 to rotate.Then, the third gear 4023 rotates along the rotating rod 4039. The positioning groove 4037 and the positioning rod 4022 limit the angle between the rotating block 4021 and the positioning block 4033 to forty-five degrees. The first motor 4013 then drives the first rotating assembly 402 and the second rotating assembly 403 to rotate, loosening the soil.
