Description

Technical Field

[0001] This invention belongs to the field of grain sorting, and specifically relates to a device for analyzing grains using fluorescence spectroscopy. Background Technology

[0002] During the analysis of oats, infrared spectroscopy is used to detect and analyze the internal components of the oats. The tested oats need to be sorted to select fully hulled oats. However, due to the light weight of oats, the oats fall too quickly during the sorting process. At the same time, the small surface area of ​​the oats exposed to the wind can cause them to fall completely before the fan blows them, resulting in insufficient sorting. In addition, some oats may adhere to the wind deflector due to the wind force, making it impossible to sort the oats.

[0003] Therefore, it is hoped that existing grain analysis devices can be optimized and improved to accommodate the thorough sorting of oats after spectral analysis. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a device for analyzing grains using fluorescence spectroscopy, thereby solving the problems of insufficient spectral analysis and subsequent sorting of oats in the prior art.

[0007] The sorting unit includes: a support platform, on the upper surface of which an air duct is fixedly connected. One end of the air duct is fixedly connected to a cylindrical outer shell that wraps around the air outlet. A baffle plate is attached to the inner surface of the outer shell and rotates around the axis of the outer shell. A connecting rod is fixedly connected to the baffle plate away from the air duct, and a rotating wheel is fixedly connected to the end of the connecting rod away from the air duct. A drive rod passes through a movable hole in the center of the rotating wheel, and a lever is mounted on the drive rod. A stop lever is also mounted on the rotating wheel. When the drive rod rotates, the stop lever causes the rotating wheel to rotate around its own axis, thereby driving the baffle plate to rotate around the outer shell. The rotating wheel is rotatably mounted on the support frame via bearings. The baffle plate has multiple axially distributed openings; each opening is penetrated by a mating pin, and the pins are fixedly connected to a movable ring.

[0008] In some disclosures, the support frame rotates around the housing axis and is slidably mounted on the support frame, the support block, and the roller brush inside the housing is in contact with the wind deflector.

[0009] In some publicly available designs, a limit block is installed between the support frame and the support block, and the support frame abuts against the support block between the limit blocks.

[0012] In some publicly available images, a storage bin is fixedly connected to the upper surface of the support plate, and a discharge port is fixedly connected to the storage bin near the inlet.

[0013] In some publicly available designs, a telescopic rod is fixedly connected to the upper surface of the support plate, and a sample slot is fixedly connected to the upper end of the telescopic rod. The sample slot is located directly below the discharge port.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This combination Figures 1 to 5 This describes an embodiment of a device for analyzing grains using fluorescence spectroscopy. Specifically, the device is constructed as a split structure, including a wind deflector 110, a connecting rod 113, and a rotating wheel 111. Rotating the rocker arm 112 drives the rotating wheel 111, which in turn drives the connecting rod 113 on the rotating wheel 111 to rotate, thereby controlling the unfolded area of ​​the wind deflector 110 and adjusting the airflow area of ​​the oats. Simultaneously, the rotation of the motor 102 also drives the support frame 109. Since a roller brush 117 is fixedly connected to the support frame 109, the roller brush 117 rotates with the support frame 109, cleaning the oats attached to the wind deflector 110 during rotation, thus achieving thorough sorting of the oats.

[0033] Please refer to Figure 1-5 An apparatus for analyzing grains by fluorescence spectroscopy, comprising:

[0034] The sorting unit is used to sort the oats.

[0035] The sorting unit includes: a support platform 1, with an air duct 104 fixedly connected to the upper surface of the support platform 1. A housing 106 is fixedly connected to one end of the air duct 104. The housing 106 is cylindrical and encloses the air outlet. A baffle plate 110 is attached to the inner surface of the housing 106 and rotates about the axis of the housing 106. A connecting rod 113 is fixedly connected to the side of the baffle plate 110 away from the air duct 104. A rotating wheel 111 is fixedly connected to the end of the connecting rod 113 away from the air duct 104. A movable hole 1110 is opened in the middle of the rotating wheel 111, and a drive rod 112 penetrates through the movable hole 1110. The drive rod 112 is equipped with... There is a toggle lever 1120; at the same time, a stop lever 1111 is provided on the rotating wheel. When the drive rod 112 rotates, the toggle lever 1120 moves the stop lever 1111, causing the rotating wheel 111 to rotate around its own axis, thereby driving the wind deflector 110 to rotate around the outer shell 106. The rotating wheel 111 is rotatably mounted on the support frame 109 through the bearing. The wind deflector 110 has multiple axially distributed openings 1102; each opening 1102 is penetrated by a matching pin 119. The pins 119 are all fixedly connected to the movable ring 115. The movable ring 115 is located between 106 and 107, and the outer diameter of the movable ring 115 is equal to the inner diameter of 106.

[0036] The windbreak 110 is folded to adjust the wind-receiving area of ​​the oats. The windbreak 110 is folded in a ring shape from one end to the other. The windbreak 110 is an essential product for constructing windbreak and dust suppression walls for various storage yards. Most of them are made of high-molecular composite materials, while some are made of aluminum-zinc coated steel plates with powder coating.

[0037] The rotating wheel 111 is controlled by rotating the rocker arm 112, which in turn drives the connecting rod 113 to rotate, thereby adjusting the size of the windshield 110. It can be used to transmit force, motion, or control the movement of other mechanical components. Common rotating wheels include wheels, rollers, and gears.

[0038] The fan delivers air into the ventilation duct 104. Oats enter the ventilation duct 104 through the feed inlet 205 for sorting. The ventilation duct 104 is a major air guiding device for local ventilation. Depending on the manufacturing material, there are flexible ventilation ducts made of canvas, artificial leather, plastic and rubber, as well as metal ventilation ducts made of sheet metal and aluminum plates.

[0039] After analysis, the oats enter the air duct 104 for sorting. When the motor 102 is turned on, the fan 103 sorts the oats inside the air duct 104. The air duct 104 provides an airflow channel during the sorting process, allowing for rapid sorting of the oats. Because the oats pass through the air duct 104 at a relatively high speed, they fall during the airflow sorting process, resulting in insufficient airflow area. At this time, the oscillating rod 1120 is rotated. The oscillating rod 1120 drives the drive rod 112 and the rotating wheel 111 to rotate, which in turn drives the baffle 110 to adjust. The baffle 110 can adjust the amount of oats falling according to the amount of oats falling. The airflow area can be adjusted. When there is too much oat, the area of ​​the baffle plate 110 can be reduced to increase the airflow area of ​​the oat. When there is a small amount, the area of ​​the baffle plate 110 can be appropriately increased to make the sorting more thorough. In some cases, the oat may adhere to the baffle plate 110 due to the wind force and needs to be cleaned. The movable ring 115 can move the pin 119. When cleaning, the movable ring 115 is moved. At this time, the pin 119 and the baffle plate 110 form a groove to guide the airflow. At the same time, the roller brush 117 and the support block 116 move towards the baffle plate 119 to clean the oat.

[0040] Before sorting oats, analysis can be performed using a spectrometer. Infrared spectroscopy can be used, taking advantage of oats' characteristic absorption of infrared light to form a specific infrared spectrum, allowing for analysis of the oat's internal structure. Alternatively, atomic absorption spectroscopy can be used, utilizing the characteristics of spectral lines and the degree of line attenuation for qualitative and quantitative analysis of the target elements. Both infrared and atomic absorption spectroscopy can be used simultaneously for detection and analysis. Infrared spectroscopy is used to detect the internal nutrients of oats, while atomic absorption spectroscopy is used to detect specific elements. For example, near-infrared spectroscopy analysis models for detecting the main nutrient content of oat hay can be referenced when performing infrared spectroscopy analysis on oats.

[0041] A power supply 3 is fixedly connected to the upper surface of the support plate 2. A support frame 301 is fixedly connected to the power supply 3 near the sample chamber 203. A xenon lamp 302 is fixedly connected to the upper surface of the support frame 301. The xenon lamp 302 is mounted on the support frame 301 to transmit power from the power supply 3 to the xenon lamp 302. When the power supply 3 is turned on, power is transmitted to the xenon lamp 302 through the support frame 301, at which point the xenon lamp 302 emits light, preparing for subsequent detection.

[0042] A slit plate 303 is fixedly connected to the upper surface of the support frame 301. The function of the slit plate is to capture light source information. When the light source enters the slit plate 303, the slit plate 303 will collect the light source information and then transmit the light source 3 to the reflector 307.

[0043] A first support frame 309 is fixedly connected to the three sides of the support frame 301 away from the power source. A first rotating shaft 308 is fixedly connected to the first support frame 309 near the power source. A reflector 307 is movably connected to the first rotating shaft 308. During the analysis process, the reflector 307 can change the direction of the light. When the light passes through the slit 303 and enters the reflector 307, the reflector 307 will reflect the light away due to the reflection. Then, the first rotating shaft 308 can be adjusted to change the direction of rotation so that the light reaches the grating 306.

[0044] A second support frame 304 is fixedly connected to the side of the support frame 301 away from the power source. A second rotating shaft 305 is fixedly connected to the end of the second support frame 304 away from the power source. A grating 306 is rotatably connected to the second rotating shaft 305. The grating can increase the light intensity during the analysis process. When the light enters the grating 306, the second rotating shaft 305 can be adjusted to allow the light to enter the sample cell 203 for analysis.

[0045] The support frame 109 rotates around the axis of the outer shell 106 and is slidably mounted on the support frame 109. A roller brush 117 is fixedly connected to the support block 116 away from the support frame 119. The roller brush 117 is provided inside the outer shell 106 and is in contact with the wind deflector 110. The support block 116 can fix the roller brush 117 and also connect the roller brush 117 to the support frame 109. During sorting, some oats will be blown to the wind deflector 110 away from the filter plate 107. This part of oats will adhere to the wind deflector 110 due to the wind force. The roller brush 117 will rotate with the rotation of the support frame 109 to clean the oats attached to the wind deflector 110. During cleaning, the brush on the surface of the roller brush 117 sweeps the attached oats by rotating.

[0046] A limiting block 118 is provided between the support frame 109 and the support block 116. The support frame 109 rotates coaxially between the limiting blocks 118, and the limiting blocks 118 abut against the support block 116. The limiting blocks 118 are fixed on the support frame 109 to prevent the support block 116 from moving towards the air duct 104 end, which would cause the roller brush 117 to lose contact with the baffle plate 110 and fail to complete the cleaning. During the cleaning process, the position of the support block 116 can also be moved according to the distance between the roller brush 117 and the baffle plate 110, so that the support block 116 and the roller brush 117 move closer to the baffle plate 110, thereby allowing the roller brush 117 to contact the baffle plate 110 and complete the cleaning of the oats.

[0047] A fan 103 is fixedly connected to the other end of the air duct 104. A motor 102 is fixedly connected to the drive shaft of the fan 103. A rotating shaft 1031 is fixedly connected to the support frame 109 near the end of the fan 103. The fan 103 and the motor 102 are designed to provide a power source. During sorting, the motor 102 is turned on to drive the fan 103. The rotating shaft 1031 is rotated to rotate the support frame 109, thereby driving the roller brush 117 to rotate for cleaning.

[0048] A drawstring 108 is attached to the side of the filter plate 7 away from the air duct 104, and the drawstring 108 is fixedly connected to the drawstring bag 105. The filter plate 107 is designed to sort out the lighter oat hulls, while the drawstring bag 105 collects the waste. During sorting, because the oat hulls are light, they are blown towards the filter plate 7 by the fan 103 and enter the drawstring bag 105. After sorting, the drawstring 108 attached to 104 is untied, the drawstring bag 105 can be removed, and the drawstring 108 can be tightened to complete the sealing. In some cases, the filter plate 107 can be replaced according to the type and shape of the oats, so that the filter holes on its surface can be adapted to the sorting of different oats.

[0049] The collection box 101 passes through the support platform 1 and is fixedly connected to the air duct 4, and the inlet 205 passes through the support plate 2 and is fixedly connected to the air duct 4. The collection box 101 and the inlet 205 are respectively set on the upper and lower surfaces of the support platform 1 to facilitate the rapid sorting of oats. During sorting, the oats enter the air duct 104 through the inlet 205. After sorting, the sorted oats enter the collection box 101 to complete the sorting process.

[0050] A storage tank 201 is fixedly connected to the upper surface of the support plate 2, and a discharge port 202 is fixedly connected to the side of the storage tank 201 near the inlet 205. The main function of the storage tank 201 and the inlet 205 is to put oats into the sample cell 203 for analysis by irradiation with power supply 3.

[0051] A telescopic rod 204 is fixedly connected to the upper surface of the support plate 2, and a sample slot 203 is fixedly connected to the upper end of the telescopic rod 204. The sample slot 203 is located directly below the discharge port 202. The sample slot 203 facilitates sample analysis and testing. The telescopic rod 204 controls the tilt angle of the sample slot 203. When oats enter the sample slot 203, the telescopic rod 204 moves upward, tilting the sample slot 203 to facilitate the entry of the light source 3 into the sample slot 203 for analysis. At the same time, the upward movement of the telescopic rod 204 causes the sample slot 203 to form an tilt angle with the support plate 2, which facilitates the rapid entry of the oats inside the sample slot 203 into the air duct 104 for sorting.

[0052] The apparatus for analyzing grains by fluorescence spectroscopy provided by the present invention will be further described below with reference to the accompanying drawings and embodiments.

A drive rod 112 is provided, and a toggle lever 1120 is provided on the drive rod 112. At the same time, a stop lever 1111 is provided on the rotating wheel. When the drive rod 112 rotates, the toggle lever 1120 moves the stop lever 1111, causing the rotating wheel 111 to rotate around its own axis, thereby driving the wind deflector 110 to rotate around the outer shell 106. The rotating wheel 111 is rotatably mounted on the support frame 109 through bearings. The wind deflector 110 has multiple axially distributed openings 1102. Each opening 1102 is penetrated by a matching pin 119, and each pin 119 is fixedly connected to the movable ring 115.

[0055] The spectral unit is used to receive the oats sorted by the sorting unit and perform spectral analysis, using infrared spectroscopy and atomic absorption spectroscopy to detect the internal components of the oats.

[0059] A drawstring 108 is tied to the side of the filter plate 7 away from the air duct 104, and the drawstring 108 is fixedly connected to the drawstring bag 105.

[0060] A telescopic rod 204 is fixedly connected to the upper surface of the support plate 2, and a sample groove 203 is fixedly connected to the upper end of the telescopic rod 204. The sample groove 203 is located directly below the discharge port 202.

[0063] During analysis, the power supply 3 is first turned on to enable the xenon lamp 302 to operate. The light emitted by the xenon lamp 302 enters the reflector 307 through the slit 303. Then, the first rotating shaft 308 is rotated to allow the light in the reflector 307 to enter the grating 306 to increase the light intensity. Next, the second rotating shaft 305 is rotated to allow the light on the grating 306 to enter the sample cell 203 for analysis.

[0064] After the analysis is completed, the raw materials enter the air duct 104. At this time, the motor 102 is turned on and the fan 103 starts to work. During sorting, the air blows the lighter oats into the filter plate 7 and into the drawstring bag 105. Then, the oscillating rod 1120 can be rotated to make the rotating wheel 111 rotate around its own axis, which in turn drives the baffle plate 110 to rotate around the outer shell 106 to adjust the size of the baffle plate 110, increase the air receiving area, and make the oats quickly sorted. The sorted oats enter the collection box 101. Due to the wind force, some oats will be blown onto the baffle plate 110.
