Description

Technical Field

[0001] The present invention relates to the technical field of component detection, and specifically to a device for quantitatively detecting the components of a feed additive. Background Art

[0002] A feed additive refers to a small amount or trace substance added during the processing, production, or use of feed. Although its dosage is small, it has a significant impact on the nutritional value of the feed, animal health, and production efficiency. Its main functions include: improving and enhancing the nutritional value of the feed, increasing the utilization efficiency of the feed, promoting animal growth and development, etc. It is mainly divided into two types: powder and liquid.

[0003] The main purpose of quantitatively detecting the components of feed additives is to ensure that feed additives meet the requirements of relevant laws and regulations, safeguard the health of animals and humans, and improve the quality and safety of feed; the most significant role is to help identify heavy metal detections (such as lead, cadmium, mercury, etc.), antibiotic residues, microorganisms (such as Salmonella, Escherichia coli, etc.), and nutritional components. The common method for detecting the components of powder additives is to use a spectrometer for detection.

[0004] Common detection devices include a mixing barrel, a conveyor belt, and a spectrometer, etc.; during use, the sample is put into the mixing barrel for mixing, and after mixing, it is discharged onto the conveyor belt. The spectrometer is arranged above the conveyor belt; when the conveyor belt conveys the mixed sample, the spectrometer can detect the sample in real time.

[0005] Since during the mixing of the powder and its transfer to the conveyor belt, some finer additive powders (with extremely small particle sizes, including a certain component with an originally extremely small particle size, and also including powders with extremely small particle sizes formed by the friction of components with originally larger particle sizes during the mixing and movement process) will be suspended in the air; since they cannot fall onto the conveyor belt, the spectrometer cannot detect them; it takes a long time for these powders to fall back onto the conveyor belt, so it is not very realistic to wait for them to fall back for detection (if the conveyor belt does not work, the samples are likely to accumulate, affecting the detection results; if the conveyor belt works, the detected samples are incomplete, which also affects the detection results).

[0071] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0072] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, which can be directly on the other element or there may also be a middle element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be a middle element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0073] Please refer to Figures 1 to 12 , in the embodiment of the present invention, a device for quantitatively detecting the components of a feed additive includes a chassis 1, and a mixing material cylinder 2, a motor 3 and a spectrometer 33 are fixedly installed on the chassis 1;

[0074] A feed inlet 201, a discharge outlet 202 and a fixing plate 203 are fixedly installed on the mixing material cylinder 2;

[0075] A mixing structure is arranged in the mixing material cylinder 2;

[0076] The chassis 1 is provided with a loading plate 13; a receiving structure is provided on the chassis 1;

[0077] A gas collecting tank 32 is fixedly installed inside the chassis 1; an intake pipe 3201 communicated with the discharge port 202 is fixedly installed on the gas collecting tank 32, and one end of the intake pipe 3201 forms an intake port 3204; a fan blade 24 is rotatably installed on the intake pipe 3201; a conical pipe 3202 and an exhaust pipe 3203 are fixedly installed on the gas collecting tank 32;

[0078] A blowing structure is provided on the chassis 1; the blowing structure can drive the fan blade 24 to rotate;

[0079] When the mixing structure operates, it can drive the receiving structure to operate, so as to drive the loading plate 13 to move towards the spectrometer 33. When the loading plate 13 passes over the discharge port 202, the mixing structure can drive the blowing structure to operate, so as to quickly flow the air in the mixing material cylinder 2 into the gas collecting tank 32.

[0080] Taking the embodiment combined with all the features described in this application as an example, during use, multiple groups of samples are quantitatively collected from multiple groups of feed additives to be detected, and the collected samples are put into the mixing material cylinder 2 from the feed port 201. Sampling separately from multiple groups of additives can effectively avoid deviation of the detection results.

[0081] Start the motor 3; thereby driving the mixing structure to operate, so as to mix the samples in the mixing material cylinder 2, improve the accuracy of the detection results, and avoid large errors between the detection results and the actual values caused by uneven distribution of components in the additive.

[0082] The mixing structure can mix the samples and transport the samples towards the discharge port 202, and finally the samples will be discharged from the discharge port 202.

[0083] The mixing structure can drive the receiving structure to operate, thereby driving the loading plate 13 to move towards the spectrometer 33; the samples discharged from the discharge port 202 will fall on the loading plate 13, and due to the continuous movement of the loading plate 13, the samples can be more evenly distributed on the loading plate 13, thereby further improving the accuracy of the detection results.

[0084] When all the samples in the mixing material cylinder 2 are discharged, the loading plate 13 just passes over the discharge port 202;

[0085] Afterwards, the mixing structure will drive the blowing structure to move, so as to drive the fan blades 24 to rotate, thereby accelerating the speed of air flowing from the discharge port 202 to the gas collecting tank 32, thereby driving the relatively fine sample powder suspended in the air of the mixing barrel 2 and the discharge port 202 to flow to the gas collecting tank 32, so as to collect the sample, thereby avoiding the incomplete detection sample causing a large error between the detection result and the actual result;

[0086] The air containing the sample powder is separated in the air collecting tank 32 , and the sample powder falls on the conical pipe 3202 and is discharged from the lower end; the air is discharged to the outside through the exhaust pipe 3203 .

[0087] The sample powder discharged from the conical pipe 3202 will fall on the carrier plate 13, and the carrier plate 13 is still moving continuously, so the sample powder can be distributed on the carrier plate 13 more evenly, further improving the detection accuracy.

[0088] When the carrier plate 13 reaches the end of the stroke, the detection probe of the spectrometer 33 is just located in the middle of the carrier plate 13. By performing component detection on the sample in the middle of the carrier plate 13 by the spectrometer 33, more accurate data can be obtained.

[0089] Through the cooperation between the mixing structure and the receiving structure, the samples can be distributed on the carrier plate 13 more evenly; after the carrier plate 13 receives most of the samples, the suspended sample powder can be effectively and quickly collected through the cooperation between the blowing structure and the gas collecting tank 32, and the collected sample powder will be more evenly covered on the collected sample surface on the carrier plate 13 or in the gap between samples; through the cooperation between the mixing structure, the receiving structure and the blowing structure, the detection efficiency and the accuracy of the detection results can be effectively improved.

[0090] In another embodiment of the present invention, the mixing structure includes a main rotating shaft 4 rotatably installed in the mixing barrel 2; and one end of the main rotating shaft 4 is fixedly connected to the output end of the motor 3, and a spiral blade 5 rotatably sealed and connected to the mixing barrel 2 is fixedly installed on the main rotating shaft 4.

[0091] Taking the embodiment combining all the features described in the present application as an example, when in use, the motor 3 rotates to drive the main shaft 4 to rotate, thereby driving the spiral blades 5 to rotate.

[0092] After the sample enters the mixing barrel 2 from the feed port 201, the rotating spiral blades 5 will continuously stir the sample and provide power for the sample to move toward the discharge port 202. Therefore, the sample is stirred and moved at the same time, thereby improving the mixing efficiency and mixing effect.

[0093] Mix multiple groups of collected samples through a mixing structure, making the distribution of each component in the samples relatively uniform, so as to improve the accuracy of the detection results.

[0094] In another embodiment of the present invention, the receiving structure includes a first rotating shaft 10 rotatably installed on the chassis 1; a spiral groove 1001 is provided on the first rotating shaft 10; a guide rod 101 is fixedly installed on the chassis 1; a follower frame 12 is provided on the chassis 1; the carrier plate 13 is fixedly connected to the follower frame 12; a guide block 1203 slidably fitted with the guide rod 101 and a sliding sleeve 11 slidably connected to the first rotating shaft 10 are fixedly installed on the follower frame 12; a first protruding column 1101 slidably fitted with the spiral groove 1001 is fixedly installed on the sliding sleeve 11; the first rotating shaft 10 is connected to the main rotating shaft 4 through a belt.

[0095] Taking the embodiment combined with all the features described in this application as an example, when in use, when the main rotating shaft 4 rotates, it will drive the first rotating shaft 10 to rotate through the belt, thereby driving the spiral groove 1001 to rotate.

[0096] Through the sliding fit between the spiral groove 1001 and the first protruding column 1101, the sliding sleeve 11 can be driven to move, and the moving direction is from one end of the chassis 1 to the other end (the direction where the spectrometer 33 is located), thereby driving the follower frame 12 to move synchronously, so as to drive the guide block 1203 to move synchronously on the guide rod 101, and the carrier plate 13 will move synchronously with the follower frame 12.

[0097] The carrier plate 13 and the follower frame 12 can be separated. When in use, a suitable carrier plate 13 is selected to be connected to the follower frame 12, so as to improve the adaptability of the device; and it helps to improve the cleaning efficiency of the device after detection.

[0098] The mixing structure and the receiving structure act simultaneously; the mixing structure will continuously discharge the samples from the discharge port 202, and the carrier plate 13 will move along the discharge port 202 under the drive of the receiving structure. Therefore, the discharged samples can be more evenly distributed on the carrier plate 13, avoiding large errors in the detection results caused by excessive accumulation or overly scattered distribution of the samples on the carrier plate 13.

[0099] In another embodiment of the present invention, a closing plate 6 is slidably fitted on the fixing plate 203; a first spring 7 is arranged on the fixing plate 203; both ends of the first spring 7 are in contact with the closing plate 6 and the fixing plate 203 respectively; a limiting groove 601 is formed on the closing plate 6; a limiting sleeve 204 is fixedly installed on the discharge port 202; a limiting post 9 that cooperates with the limiting groove 601 is slidably fitted in the limiting sleeve 204; a second spring 8 is arranged in the limiting sleeve 204; both ends of the second spring 8 are in contact with the limiting sleeve 204 and the limiting post 9 respectively; a second protrusion 1202 that cooperates with the limiting post 9 and a first protrusion 1201 that cooperates with the closing plate 6 are fixedly installed on the follower frame 12.

[0100] Taking the embodiment combined with all the features described in this application as an example, during use, in the initial state, the limiting post 9 and the limiting groove 601 are mutually fitted, and the end of the limiting post 9 is an arc surface. At this time, the closing plate 6 does not cooperate with the discharge port 202, so that the sample can smoothly pass through the discharge port 202 and reach the carrier plate 13; the first spring 7 is in a compressed state; and the first protrusion 1201 is in contact with one end of the closing plate 6; the second protrusion 1202 is in contact with the bottom end of the closing plate 6.

[0101] When the receiving structure acts, the follower frame 12 will drive the first protrusion 1201 and the second protrusion 1202 to move synchronously. Therefore, the first protrusion 1201 will be separated from the contact with the closing plate 6, and the second protrusion 1202 will slide along the surface of the closing plate 6.

[0102] When all the samples in the mixing cylinder 2 are discharged, the receiving structure drives the follower frame 12 to just cross over the discharge port 202. At this time, the second protrusion 1202 just contacts the limiting post 9.

[0103] After that, the receiving structure continues to act, so as to drive the second protrusion 1202 to squeeze the limiting post 9, so that the limiting post 9 moves inward in the limiting sleeve 204 to compress the second spring 8; and when the limiting post 9 moves to the slope surface and contacts the limiting groove 601, the elastic force of the first spring 7 will drive the closing plate 6 to move, so as to further accelerate the displacement of the limiting post 9, so that the limiting post 9 is separated from the cooperation with the limiting groove 601.

[0104] The elastic force of the first spring 7 will drive the closing plate 6 to move towards the discharge port 202. At the end of the stroke, the closing plate 6 blocks the discharge port 202, so as to prevent the air flow from moving from the discharge port 202 direction to the intake pipe 3201 direction when the subsequent air blowing structure acts, and drive the samples evenly distributed on the carrier plate 13 to move, resulting in uneven dispersion of the samples and large errors in the detection results.

[0105] The main rotating shaft 4 is driven to reverse by the motor 3, so as to drive the first rotating shaft 10 to reverse, thereby driving the follower frame 12 to move in the reverse direction to complete the reset.

[0106] During the reset process, the first protrusion 1201 will contact the closing plate 6 and drive the closing plate 6 to move synchronously after the contact, compressing the first spring 7; and when the follower frame 12 is reset, the limiting groove 601 moves to directly below the limiting post 9, and under the elastic force of the second spring 8, the limiting post 9 will re-enter the limiting groove 601. Through the mutual cooperation of the limiting groove 601 and the limiting post 9, the closing plate 6 no longer displaces, so that the discharge port 202 is re-opened.

[0107] In another embodiment of the present invention, the air blowing structure includes a second large pulley 21 rotatably installed on the discharge port 202; a second small pulley 2401 is fixedly installed on the fan blade 24; the second large pulley 21 and the second small pulley 2401 are connected by a belt; a second turntable 19 is fixedly installed on the second large pulley 21; a fixed rod 16 is fixedly installed on the air collection tank 32, and a connecting rod 15 slidably engaged with the main rotating shaft 4 is slidably installed on the fixed rod 16; a first large pulley 14 slidably engaged with the main rotating shaft 4 is rotatably installed at one end of the connecting rod 15; a first small pulley 17 is rotatably installed at the other end of the connecting rod 15; the first large pulley 14 and the first small pulley 17 are connected by a belt; a first turntable 18 is fixedly installed on the first small pulley 17; a plurality of groups of meshing teeth 20 are fixedly installed on both the first turntable 18 and the second turntable 19; a lead screw column 401 is fixedly installed on the main rotating shaft 4; an internal thread sleeve 22 is threadedly connected to the lead screw column 401; a stop rod 23 cooperating with the connecting rod 15 is slidably installed on the internal thread sleeve 22, and a third spring 34 fixedly connected to the internal thread sleeve 22 is fixedly installed on the stop rod 23.

[0108] Taking the embodiment combined with all the features described in this application as an example, when in use, when the main rotating shaft 4 rotates, it will drive the lead screw column 401 to rotate synchronously, and drive the internal thread sleeve 22 to move towards the mixing cylinder 2 through thread cooperation, thereby driving the stop rod 23 to move synchronously.

[0109] During the movement of the stop rod 23, it will first contact the connecting rod 15 and drive the connecting rod 15 to move synchronously after the contact (the elastic force of the third spring 34 is relatively large), thereby driving the first large pulley 14 and the first small pulley 17 to move synchronously, so that the first turntable 18 approaches the second turntable 19.

[0110] After the closing plate 6 blocks the discharge port 202, the first turntable 18 and the second turntable 19 cooperate with each other, and the tooth blocks 20 on the two mesh with each other, so that the second turntable 19 rotates synchronously with the first turntable 18 to drive the second large pulley 21 to rotate, and the second small pulley 2401 rotates through the belt, so that the fan blades 24 rotate synchronously.

[0111] Through the acceleration of the first large pulley 14 and the first small pulley 17 and the second large pulley 21 and the second small pulley 2401, the rotation speed of the fan blades 24 is much greater than the rotation speed of the main rotating shaft 4.

[0112] After that, when the main rotating shaft 4 rotates, the fan blades 24 will rotate rapidly to accelerate the flow of air in the mixing cylinder 2 into the air collecting tank 32 to collect the suspended sample powder.

[0113] And while the fan blades 24 are rotating, the screw rod column 401 is still rotating, so as to drive the internally threaded sleeve 22 to move. At this time, the stop rod 23 is blocked by the connecting rod 15, so the internally threaded sleeve 22 compresses the third spring 34.

[0114] The air in the mixing cylinder 2 quickly enters the air collecting tank 32 through the air inlet pipe 3201. Under the action of centrifugal force and the airflow, the sample powder will move spirally downward close to the inner wall of the air collecting tank 32 and gather on the conical pipe 3202, and is discharged from the outlet end of the conical pipe 3202, while the air will be discharged outward through the exhaust pipe 3203.

[0115] The discharged powder will fall on the moving carrier plate 13, so that the sample powder is more evenly distributed on the carrier plate 13 (covering the surface of the sample discharged from the discharge port 202 or the gap between samples).

[0116] Through the mutual cooperation of the air blowing structure and the air collecting tank 32, it is possible to accelerate the collection of the suspended sample powder on the mixing cylinder 2 and the discharge port 202, avoid errors in the test results caused by incomplete samples, and improve the test efficiency.

[0117] In another embodiment of the present invention, a rotating block 29 is rotatably and sealingly installed on the air inlet pipe 3201; an opening and closing inclined groove 2901 is provided on the rotating block 29; a plurality of groups of mutually cooperating conducting plates 30 are rotatably installed on the circumference of the air inlet pipe 3201; and a third protruding column 3001 slidably fitted with the rotating block 29 is fixedly installed on the conducting plate 30.

[0118] Taking the embodiment combining all the features recorded in the present application as an example, when in use, in the initial state, the conduction plates 30 conflict with each other to block the discharge port 202 and the air inlet duct 3201, so as to prevent samples with larger particle sizes from entering the air inlet duct 3201 during the falling process of the samples, and when the blowing structure is in action, the sample cannot be driven to move, thereby making the detected sample incomplete, resulting in a large error in the detection result.

[0119] When the first turntable 18 cooperates with the second turntable 19, the rotating block 29 rotates, thereby driving the opening and closing inclined slot 2901 to rotate, and through the sliding cooperation with the third protruding column 3001, driving the conducting plate 30 to rotate, so as to connect the discharge port 202 and the air inlet pipe 3201; thereby, the suspended sample powder can smoothly enter the gas collecting tank 32.

[0120] In another embodiment of the present invention, a second pulley 28 is fixedly mounted on the rotating block 29; a second rotating shaft 26 is rotatably mounted on the discharge port 202; a first pulley 27 is fixedly mounted on the second rotating shaft 26; the first pulley 27 and the second pulley 28 are connected by a belt; a matching groove is provided on the second rotating shaft 26; a movable sleeve 25 fixedly connected to the internal threaded sleeve 22 is slidably mounted on the second rotating shaft 26; a second protruding column 2501 slidably engaged with the matching groove is fixedly mounted on the movable sleeve 25.

[0121] In another embodiment of the present invention, the matching groove includes a first straight groove 2601, an inclined groove 2602 and a second straight groove 2603; wherein the two ends of the inclined groove 2602 are respectively connected to one end of the first straight groove 2601 and one end of the second straight groove 2603.

[0122] Taking the embodiment combining all the features described in the present application as an example, when in use, when the screw column 401 rotates, the internal threaded sleeve 22 drives the movable sleeve 25 to move synchronously, thereby driving the second protruding column 2501 to slide in the matching groove.

[0123] The second protruding column 2501 will first slide in the first straight groove 2601 . At this time, the second rotating shaft 26 does not rotate, and the first rotating disk 18 and the second rotating disk 19 do not match.

[0124] Afterwards, the second protruding column 2501 will slide in the inclined groove 2602, and the second rotating shaft 26 will rotate through the squeezing effect between the second protruding column 2501 and the inclined groove 2602, thereby driving the first pulley 27 to rotate, and the second pulley 28 to rotate through the belt, thereby driving the rotating block 29 to rotate, so that the conducting plate 30 rotates, thereby conducting the discharge port 202 and the air intake duct 3201. In this process, the first rotating disk 18 and the second rotating disk 19 cooperate with each other to make the fan blades 24 rotate quickly.

[0125] Subsequently, the second protruding column 2501 will slide in the second straight groove 2603 while the second rotating shaft 26 does not rotate to maintain the conducting state. During this process, the fan blade 24 continues to rotate.

[0126] In another embodiment of the present invention, the intake duct 3201 is located tangentially to the air collecting tank 32; and the exhaust duct 3203 is vertically installed at the middle position of the air collecting tank 32 and is in communication with the outside at one end.

[0127] Taking the embodiment combined with all the features described in this application as an example, during use, the intake duct 3201 is located tangentially to the air collecting tank 32, so that after the air flow enters the air collecting tank 32 from the intake duct 3201, it will flow along the circumferential direction of the air collecting tank 32, and under the action of gravity, the air flow will spiral downward; during this process, the sample powder will move downward in a spiral manner.

[0128] When the air flow reaches the end of the flow, an internal eddy current will be formed, so that it can be discharged outward through the exhaust duct 3203. And the powder will be discharged onto the carrier plate 13 along the conical duct 3202.

[0129] In another embodiment of the present invention, a baffle 402 is fixedly installed on the main rotating shaft 4; a return spring 31 is wound around the main rotating shaft 4; and both ends of the return spring 31 are in contact with the baffle 402 and the first large pulley 14 respectively.

[0130] Taking the embodiment combined with all the features described in this application as an example, during use, when the first turntable 18 approaches the second turntable 19, the return spring 31 will be compressed.

[0131] The elastic force of the return spring 31 will drive the first large pulley 14 to reset during the reset process, so that the first turntable 18 is separated from the second turntable 19 and resets.
