Description

Technical Field

[0001] This invention belongs to the field of sample testing technology, and specifically relates to a high-throughput sample testing device for fertilizer production. Background Technology

[0002] With the increasing demand for precise quality control of fertilizers in modern agriculture, high-throughput fertilizer testing technology has become crucial for improving production efficiency and product compliance. Existing high-throughput fertilizer production sample testing devices integrate multi-channel parallel detection technology, automated sample pretreatment systems, and intelligent data analysis algorithms. These devices can simultaneously and rapidly detect over 20 indicators in fertilizers, including nitrogen, phosphorus, potassium, organic matter, heavy metals, and microbial activity. The throughput for a single test is 12-24 samples, and the testing efficiency is more than 10 times higher than traditional methods (e.g., the chloride ion detection cycle is shortened to 15 minutes per sample). The detection accuracy meets national standards (error ≤ 0.5%). Through multi-parameter integrated detection and expert decision-making systems, these devices can automatically generate fertilization recommendations and risk assessment reports, and support the uploading of test data to regulatory platforms, enabling full-process traceability management.

[0003] The following shortcomings still exist in the existing technology:

[0004] The contradiction between sample homogenization and stability: Existing devices usually require the samples to be pretreated to a homogeneous state and a specified temperature. However, during the transfer of samples to the detection chamber and the waiting process for detection, high-density components (such as heavy metal particles and incompletely dissolved nutrient complexes) are prone to precipitation due to the influence of gravity and ambient temperature. This leads to uneven distribution of the components in the test sample, inaccurate sample temperature, significantly reduced repeatability and accuracy of test results, and affects the accurate assessment of fertilizer quality.

[0005] The conflict between cleaning and efficiency of the stirring module: To meet the homogenization requirements, some devices have built-in stirring modules to achieve online mixing of samples; however, the stirring mechanism is located in a closed detection chamber, which makes cleaning the residue after detection very difficult; currently, it can only be cleaned manually by disassembling the stirring components, which takes a long time for each maintenance; in the case of mass production, this inefficient cleaning method will seriously restrict the efficiency of continuous detection, and may even lead to the interruption of the detection process, affecting the overall production schedule.

[0006] Therefore, it is necessary to invent a high-throughput fertilizer production sample testing device to solve the above problems. It can enable timely testing after sample pretreatment, and at the same time facilitate internal cleaning, thereby improving testing efficiency. Summary of the Invention

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0045] This invention provides, for example Figure 1-16 The high-throughput fertilizer production sample testing device shown includes a sample testing support and positioning mechanism 1. A limiting mechanism 3 is rotatably connected to the bottom end of the inner wall of the sample testing support and positioning mechanism 1. A sample positioning mechanism 4 is connected to the middle position of the limiting mechanism 3.

[0046] The limiting mechanism 3 includes a rotating frame 301;

[0047] The sample positioning mechanism 4 includes a positioning seat 401 rotatably mounted on the bottom of the inner wall of a rotating frame 301. Multiple positioning posts 405 are fixedly mounted on the top of the positioning seat 401. A fixed seat 402 is connected to the top of each positioning post 405. A positioning screw 407 is rotatably connected to the middle position of the bottom of the fixed seat 402. A lifting seat 408 is threadedly connected to one end of the outer wall of the positioning screw 407. Multiple lifting frames 409 are fixedly mounted on the outer wall of the lifting seat 408. A heating base 410 is fixedly mounted on one end of each lifting frame 409. The middle position of each lifting seat 408 is inserted into one end of the outer wall of each positioning post 405. The bottom end of the outer wall of the positioning screw 407... A positioning gear ring 411 is fixedly provided. A positioning groove 415 is provided in the middle of the bottom of the positioning seat 401. A first positioning gear 412 is rotatably connected to one end of the positioning groove 415. An intermittent gear 417 is fixedly provided at the bottom end of the first positioning gear 412. A second positioning gear 413 is meshed with the tooth surface of the intermittent gear 417. One side of the second positioning gear 413 is rotatably connected to the inner wall of the positioning groove 415. One side of the tooth surface of the first positioning gear 412 meshes with the tooth surface of the positioning gear ring 411. A control gear ring 416 is fixedly provided on one side of the inner wall of the positioning groove 415. The tooth surface of the second positioning gear 413 meshes with the tooth surface of the control gear ring 416.

[0048] Multiple limiting seats 403 are fixedly provided on the outer wall of the fixed seat 402, and a positioning ring 404 is fixedly provided at one end of each of the multiple limiting seats 403.

[0049] A first limiting groove 304 is provided at the middle position of the bottom of the rotating frame 301. A first drive motor 406 is fixedly provided at the middle position of the first limiting groove 304. The output end of the first drive motor 406 is fixedly connected to the bottom end of the positioning screw 407. A through groove 414 is provided at the middle position of the positioning seat 401. The outer wall of the positioning screw 407 does not contact the inner wall of the through groove 414.

[0050] When a high-throughput fertilizer production sample testing device is needed, the waste sample to be tested is diluted and placed in multiple sample reagent bottles 7. These bottles are then placed inside corresponding positioning rings 404. The output of the first drive motor 406, fixed to the bottom of the rotating frame 301, drives the positioning screw 407 to rotate. This causes the lifting seat 408, threaded onto the outer wall of the positioning screw 407, to rise and fall along multiple positioning posts 405. This, in turn, causes multiple lifting frames 409, fixed to the outer wall of the lifting seat 408, to drive multiple heating elements. The base 410 is raised and lowered, causing the heated base 410 to move the sample reagent bottle 7 at the top downwards. Through the positioning of multiple limiting seats 403 and multiple positioning rings 404 fixed to the outer wall of the fixed base 402, the outer edge of the sample reagent bottle 7 contacts the top of multiple rotating toothed rings 504 respectively. The bottom of the outer edge of the sample reagent bottle 7 is anti-slip contacted by anti-slip pads 505 fixed to the top of the rotating toothed rings 504, ensuring that all sample reagent bottles 7 move downwards stably. During the downward movement of the lifting base 408, the bottom of the outer wall of the positioning screw 407 is fixed... The tooth surface of the positioning gear ring 411 at the end meshes with the tooth surface of the first positioning gear 412, causing the intermittent gear 417 fixed at the bottom end of the first positioning gear 412 to rotate synchronously. When the lifting seat 408 descends to a certain position, the tooth surface of the intermittent gear 417 meshes with the tooth surface of the second positioning gear 413. At the same time, the tooth surface of the second positioning gear 413 meshes with the tooth surface of the control gear ring 416, causing the control gear ring 416 to drive the positioning seat 401, the fixed seat 402, the lifting seat 408, and the multiple sample reagent bottles 7 to rotate. This allows the sample reagent bottle 7 to rotate from directly below the detection contact end 208 to directly below the stirring shaft 207 as it moves to the bottom, facilitating stirring of the sample inside. When the first drive motor 406 rotates in the opposite direction, the sample reagent bottle 7 moves upward via the lifting seat 408, rotating from directly below the stirring shaft 207 to directly below the detection contact end 208, and is subsequently lifted upwards until the top of the sample reagent bottle 7 is higher than the rotating gear ring 504. Figure 8 As shown, this facilitates the retrieval of sample reagent bottle 7; at the same time, the sample positioning mechanism 4 enables the sample reagent bottle 7 to have a lifting and directional change movement tendency, making it easy to lift the sample reagent bottle 7 when it is picked up, avoiding the potential problem of the sample reagent bottle 7 slipping. In addition, by changing the angle of the sample reagent bottle 7, it is easy to stir and test the sample in the sample reagent bottle 7, making the operation process smooth.

[0051] In one specific embodiment of the present invention, a plurality of connecting frames 302 are fixedly provided at the top end of the inner wall of the rotating frame 301. One end of the plurality of connecting frames 302 is connected to a support base 303, and the bottom end of the support base 303 is connected to a sample rotation control mechanism 5. The sample rotation control mechanism 5 includes a drive gear ring 502 that rotates at the bottom end of the support base 303. A plurality of control gears 503 are meshed with the outer wall of the drive gear ring 502, and the top ends of the plurality of control gears 503 are rotatably connected to the bottom end of the support base 303. A first reduction motor 501 is fixedly installed at one end of the middle position. The output end of the first reduction motor 501 is fixedly connected to the middle position of one of the control gears 503. The top ends of multiple positioning rings 404 are rotatably connected to rotating gear rings 504. The tooth surfaces of multiple control gears 503 respectively mesh with the tooth surfaces of multiple rotating gear rings 504. The top ends of multiple rotating gear rings 504 are fixedly provided with anti-slip pads 505. The bottom ends of the drive gear ring 502 and the bottom ends of multiple control gears 503 do not contact the top end of the fixed seat 402.

[0052] When the sample reagent bottle 7 rotates to directly below the stirring shaft 207, the tooth surface of the rotating gear ring 504 rotating at the top of the positioning ring 404 meshes with the tooth surface of the corresponding control gear 503. The output end of the first reduction motor 501 fixed on one side of the support base 303 drives one of the control gears 503 to rotate. Through the transmission meshing of the driving gear ring 502, multiple control gears 503 drive multiple rotating gear rings 504 and the sample reagent bottle 7 to rotate synchronously, assisting the stirring shaft 207 in homogenization. At the same time, the sample temperature is controlled by controlling the heating base 410. Rotating the sample reagent bottle 7 helps to equalize the internal sample temperature and improve the accuracy of sample detection data.

[0053] The tops of multiple rotating toothed rings 504 are in anti-slip contact with sample reagent bottles 7 via anti-slip pads 505, and the bottoms of the outer walls of multiple sample reagent bottles 7 are in contact with the inner walls of multiple heating bases 410 respectively.

[0054] In one specific embodiment of the present invention, the sample detection support and positioning mechanism 1 includes a support and positioning base 101. A support frame 103 is fixedly provided at one end of the support and positioning base 101. A sliding groove 104 is provided in the middle position of the support frame 103. A control screw 105 is rotatably connected to the middle position of the sliding groove 104. A sliding frame 106 is threadedly connected to one end of the outer wall of the control screw 105. A protective cover 102 is fixedly connected to one end of the sliding frame 106. A second limiting groove 107 is provided on both sides of the inner wall of the sliding groove 104. The two sides of the sliding frame 106 are slidably connected to the inner walls of the two second limiting grooves 107 respectively. A second drive motor 108 is fixedly provided at the bottom end of the inner wall of the support frame 103. The output end of the second drive motor 108 is fixedly connected to the bottom end of the control screw 105.

[0055] The output end of the second drive motor 108 fixed to the bottom of the support frame 103 drives the control screw 105 to rotate, so that the sliding frame 106 threaded to the outer wall of the control screw 105 moves up and down along the inner wall of the sliding groove 104, so that the protective cover 102 fixed to one end of the sliding frame 106 can be easily raised and lowered. During the test, the protective cover 102 stably protects the top of the rotating frame 301. The telescopic end of the first electric telescopic rod 201 fixed to the top of the protective cover 102 drives the detection and auxiliary detection mechanism 2 to move up and down. When the detection and auxiliary detection mechanism 2 moves to the top of the protective cover 102, the bottom of the detection and auxiliary detection mechanism 2 is still higher than the top of the rotating frame 301, so as to avoid collision with the limiting mechanism 3 when not stirring or testing.

[0056] When the sample reagent bottle 7 moves to the bottom of the stirring shaft 207, the first electric telescopic rod 201, fixed in the middle of the protective cover 102, drives the lifting plate 202 to move downward, so that the stirring shaft 207 extends into the interior of the sample reagent bottle 7. The second reduction motor 206, fixed at the top of the first positioning platform 204, drives the stirring shaft 207 to rotate, so that the sample in the sample reagent bottle 7 is homogenized. After processing, the lifting plate 202 is raised, and the first drive motor 406 controls the sample reagent bottle 7 to rotate, so that the sample reagent bottle 7 rotates to the bottom of the detection contact end 208. The detection contact end 208 is inserted for detection and analysis. After the analysis is completed, the protective cover 102 is moved upward, and the sample reagent bottle 7 is moved upward to replace the sample.

[0057] In one specific embodiment of the present invention, a detection and auxiliary detection mechanism 2 is connected to the top of the inner wall of the sample detection support positioning mechanism 1. The detection and auxiliary detection mechanism 2 includes a first electric telescopic rod 201 fixed to the top of the protective cover 102. The telescopic end of the first electric telescopic rod 201 is fixedly connected to a lifting plate 202. A plurality of first positioning platforms 204 are fixedly connected to the outer wall of the lifting plate 202. A stirring shaft 207 is rotatably connected to the bottom of each of the plurality of first positioning platforms 204. A second reduction motor 206 is fixedly connected to the top of each of the plurality of first positioning platforms 204. The output ends of the plurality of second reduction motors 206 are respectively fixedly connected to the top of the plurality of stirring shafts 207. A plurality of second positioning platforms 205 are also fixedly connected to the outer wall of the lifting plate 202. A detection contact end 208 is inserted and connected to the bottom of each of the plurality of second positioning platforms 205. A fertilizer detector 203 is fixedly connected to the middle position of the top of the lifting plate 202. One end of each of the plurality of detection contact ends 208 is stably connected to the outer wall of the fertilizer detector 203.

[0058] In one specific embodiment of the present invention, the bottom end of the rotating frame 301 is connected to an auxiliary cleaning mechanism 6, which includes a cleaning control water pump 601. An installation groove 306 is provided at the middle position of the bottom of the rotating frame 301. The cleaning control water pump 601 is positioned inside the installation groove 306 and is connected to an external water source. The outer wall of the cleaning control water pump 601 is connected to multiple cleaning frames 603 through multiple guide pipes 602. Multiple cleaning grooves 305 are provided at the bottom end of the inner wall of the rotating frame 301. The outer walls of the multiple cleaning frames 603 slide in contact with the inner walls of the multiple cleaning grooves 305 respectively. Multiple second electric telescopic rods 604 are fixedly connected to the bottom end of the rotating frame 301. The telescopic ends of the multiple second electric telescopic rods 604 are fixedly connected to the bottom ends of the multiple cleaning frames 603 respectively. A protective groove 109 is provided at the top end of the supporting positioning base 101. The outer walls of the multiple second electric telescopic rods 604 are all located inside the protective groove 109.

[0059] When the sample in sample reagent bottle 7 is being tested and analyzed, the stirring shaft 207 also moves downward to the corresponding position. The extension end of the second electric telescopic rod 604, which is fixed to the bottom of the rotating frame 301, drives the cleaning frame 603 to rise and fall along the cleaning tank 305, so that the stirring shaft 207 is immersed in the interior of the cleaning frame 603. The cleaning control water pump 601 controls the pumping in and out of the cleaning liquid inside the cleaning frame 603. At the same time, the stirring rod is cleaned by controlling the rotation of the stirring shaft 207. This allows the stirring rod to be cleaned while the sample is being tested, reducing the preparation time for the next test and improving the efficiency of batch testing.
