Description

Technical Field

[0001] The invention relates to the technical field of component detection, in particular to a device for quantitatively detecting components of feed additives. Background Art

[0002] Feed additives refer to small or trace substances added during feed processing, production or use. Although the amount used is small, it has a significant impact on the nutritional value of feed, animal health and production efficiency. Its main functions include: improving and strengthening the nutritional value of feed, improving feed utilization efficiency, and promoting animal growth and development. It is mainly divided into two types: powder and liquid.

[0003] The main purpose of quantitative testing of feed additive ingredients is to ensure that feed additives comply with the requirements of relevant laws and regulations, protect the health of animals and humans, and improve the quality and safety of feed; the most significant role is to help identify heavy metal detection (such as lead, cadmium, mercury, etc.), antibiotic residues, microorganisms (such as Salmonella, E. coli, etc.) and nutrients. The common way to test the ingredients of powder additives is to use a spectrometer.

[0004] Common detection devices include a mixing barrel, a conveyor belt, and a spectrometer. When in use, the sample is put into the mixing barrel for mixing, and then discharged onto the conveyor belt after mixing. The spectrometer is set above the conveyor belt. When the conveyor belt transports the mixed sample, the spectrometer can detect the sample in real time.

[0005] During the mixing and transfer of powders to the conveyor belt, some finer additive powders (with extremely small particle sizes, including a certain component with extremely small particle sizes, and also including extremely small powders formed by 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 realistic to wait for them to fall back before testing (if the conveyor belt is not working, samples are prone to accumulation, affecting the test results; if the conveyor belt is working, the tested samples are incomplete, which also affects the test results).

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0033] See also Figures 1 to 12 In an embodiment of the present invention, a quantitative detection device for the composition of feed additives includes a chassis 1, on which a mixing barrel 2, a motor 3 and a spectrometer 33 are fixedly mounted; The mixing barrel 2 is fixedly provided with a feed port 201, a discharge port 202 and a fixing plate 203; The mixing barrel 2 is provided with a mixing structure; The chassis 1 is provided with a loading plate 13; the chassis 1 is provided with a receiving structure; The chassis 1 is fixedly provided with an air collecting tank 32; an air inlet pipe 3201 communicating with the discharge port 202 is fixedly provided on the air collecting tank 32, and an air inlet port 3204 is formed at one end of the air inlet pipe 3201; a fan blade 24 is rotatably provided on the air inlet pipe 3201; a conical pipe 3202 and an exhaust pipe 3203 are fixedly provided on the air collecting tank 32; The chassis 1 is provided with an air blowing structure; the air blowing structure can drive the fan blades 24 to rotate; When the mixing structure is in motion, it can drive the receiving structure to move, so as to drive the carrier plate 13 to move toward the spectrometer 33 , and when the carrier plate 13 passes over the discharge port 202 , the mixing structure can drive the blowing structure to move, so as to quickly make the air in the mixing barrel 2 flow into the air collecting tank 32 .

[0034] Taking the embodiment of all the features combined in this application as an example, when in use, multiple groups of samples are quantitatively collected from multiple groups of feed additives to be tested, and the collected samples are put into the mixing barrel 2 from the feed inlet 201. Sampling from multiple groups of additives separately can effectively avoid deviations in the test results.

[0035] Start the motor 3, thereby driving the mixing structure to move, so as to mix the sample in the mixing barrel 2, so as to improve the accuracy of the test result and avoid the uneven distribution of the components in the additive, which may cause a large error between the test result and the actual value.

[0036] The mixing structure can mix the samples and transport the samples toward the discharge port 202 , and the samples will eventually be discharged from the discharge port 202 .

[0037] The mixed structure can drive the receiving structure to move, thereby driving the carrier plate 13 to move toward the spectrometer 33; the sample discharged from the discharge port 202 will fall on the carrier plate 13, and because the carrier plate 13 continues to move, the sample can be distributed more evenly on the carrier plate 13, thereby further improving the accuracy of the detection results.

[0038] When all the samples in the mixing barrel 2 are discharged, the carrier plate 13 just passes over the discharge port 202; 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; 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 .

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] The multiple groups of collected samples are mixed through the mixing structure so that the distribution of each component in the sample is more uniform, thereby improving the accuracy of the test results.

[0046] In another embodiment of the present invention, the supporting structure includes a first rotating shaft 10 rotatably mounted on the chassis 1; a spiral groove 1001 is opened on the first rotating shaft 10; a guide rod 101 is fixedly mounted on the chassis 1; a follower frame 12 is provided on the chassis 1; the loading plate 13 is fixedly connected to the follower frame 12; a guide block 1203 slidably engaged with the guide rod 101 and a sliding sleeve 11 slidably connected to the first rotating shaft 10 are fixedly mounted on the follower frame 12; a first protruding column 1101 slidably engaged with the spiral groove 1001 is fixedly mounted on the sliding sleeve 11; the first rotating shaft 10 and the main rotating shaft 4 are connected by a belt.

[0047] Taking the embodiment combining all the features described in the present application as an example, when in use, the main shaft 4 rotates, which drives the first shaft 10 to rotate through the belt, thereby driving the spiral groove 1001 to rotate.

[0048] Through the sliding cooperation 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, thereby driving the guide block 1203 to move synchronously on the guide rod 101, and the loading plate 13 will move synchronously with the follower frame 12.

[0049] The carrier plate 13 and the follower frame 12 are separable. When in use, a suitable carrier plate 13 is selected to be connected with the follower frame 12, thereby improving the adaptability of the device and helping to improve the cleaning efficiency of the device after detection.

[0050] The mixing structure moves while the receiving structure moves; the mixing structure will continuously discharge the sample from the discharge port 202, and the carrier plate 13 will move along the discharge port 202 driven by the receiving structure, so that the discharged sample can be distributed more evenly on the carrier plate 13, avoiding excessive accumulation of the sample on the carrier plate 13 or excessive dispersion, which may lead to large errors in the detection results.

[0051] In another embodiment of the present invention, a closing plate 6 is slidably engaged with the fixed plate 203; a first spring 7 is provided on the fixed plate 203; two ends of the first spring 7 respectively contact with the closing plate 6 and the fixed plate 203; a limiting groove 601 is provided on the closing plate 6; a limiting sleeve 204 is fixedly installed on the discharge port 202; a limiting column 9 cooperating with the limiting groove 601 is slidably engaged in the limiting sleeve 204; a second spring 8 is provided in the limiting sleeve 204; two ends of the second spring 8 respectively contact with the limiting sleeve 204 and the limiting column 9; a second protrusion 1202 cooperating with the limiting column 9 and a first protrusion 1201 cooperating with the closing plate 6 are fixedly installed on the follower frame 12.

[0052] Taking the embodiment combining all the features described in this application as an example, when in use, in the initial state, the limiting column 9 and the limiting groove 601 are mutually engaged, and the end of the limiting column 9 is an arc surface. At this time, the closing plate 6 and the discharge port 202 do not cooperate, so that the sample can smoothly pass through the discharge port 202 to the loading plate 13; the first spring 7 is in a compressed state; and the first protrusion 1201 contacts one end of the closing plate 6; the second protrusion 1202 contacts the bottom end of the closing plate 6.

[0053] When the receiving structure moves, the follower frame 12 drives the first protrusion 1201 and the second protrusion 1202 to move synchronously, so that the first protrusion 1201 will be out of contact with the closing plate 6, and the second protrusion 1202 will slide along the surface of the closing plate 6.

[0054] When all the samples in the mixing barrel 2 are discharged, the receiving structure drives the follower frame 12 to just pass over the discharge port 202. At this time, the second protrusion 1202 just contacts the limiting column 9.

[0055] After that, the supporting structure continues to move, thereby driving the second protrusion 1202 to squeeze the limit column 9, so that the limit column 9 moves inward in the limit sleeve 204 to compress the second spring 8; and when the limit column 9 moves to the slope surface and contacts the limit 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 limit column 9, so that the limit column 9 and the limit groove 601 are out of engagement.

[0056] The elastic force of the first spring 7 will drive the closing plate 6 to move toward the discharge port 202. At the end of the stroke, the closing plate 6 blocks the discharge port 202 to prevent the air flow from moving from the discharge port 202 to the air inlet duct 3201 when the subsequent blowing structure is actuated, thereby driving the evenly distributed samples on the carrier plate 13 to move, causing the samples to be unevenly dispersed, resulting in a large error in the detection result.

[0057] The motor 3 drives the main rotating shaft 4 to rotate reversely, thereby driving the first rotating shaft 10 to rotate reversely, thereby driving the follower frame 12 to move in the opposite direction to complete the reset.

[0058] During the resetting process, the first protrusion 1201 will contact the closing plate 6, and after the contact, it will drive the closing plate 6 to move synchronously, compressing the first spring 7; and when the follower frame 12 is reset, the limit groove 601 moves to just below the limit column 9, and under the action of the elastic force of the second spring 8, the limit column 9 will re-enter the limit groove 601 in the machine, and through the mutual cooperation between the limit groove 601 and the limit column 9, the closing plate 6 will no longer move, thereby allowing the discharge port 202 to be reopened.

[0059] In another embodiment of the present invention, the blast structure includes a second large pulley 21 rotatably mounted on the discharge port 202; a second small pulley 2401 is fixedly mounted 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 mounted on the second large pulley 21; a fixed rod 16 is fixedly mounted on the gas collecting tank 32, and a connecting rod 15 slidably mounted on the fixed rod 16 and slidably engaged with the main rotating shaft 4; a first large pulley 14 slidably engaged with the main rotating shaft 4 is rotatably mounted on one end of the connecting rod 15; the other end of the connecting rod 15 A first small pulley 17 is rotatably mounted on one end; the first large pulley 14 is connected to the first small pulley 17 by a belt; a first turntable 18 is fixedly mounted on the first small pulley 17; a plurality of groups of mutually meshing tooth blocks 20 are fixedly mounted on the first turntable 18 and the second turntable 19; a screw column 401 is fixedly mounted on the main shaft 4; an internally threaded sleeve 22 is threadedly connected to the screw column 401; a blocking rod 23 cooperating with the connecting rod 15 is slidably mounted on the internally threaded sleeve 22, and a third spring 34 fixedly connected to the internally threaded sleeve 22 is fixedly mounted on the blocking rod 23.

[0060] Taking the embodiment combining all the features recorded in this application as an example, when in use, when the main shaft 4 rotates, it will drive the screw column 401 to rotate synchronously, and drive the internal threaded sleeve 22 to move toward the mixing barrel 2 through thread cooperation, thereby driving the blocking rod 23 to move synchronously.

[0061] During the movement of the blocking rod 23, it will first collide with the connecting rod 15, and after the collision, it will drive the connecting rod 15 to move synchronously (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 is close to the second turntable 19.

[0062] When 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 thereon engage with each other, so that the second turntable 19 rotates synchronously with the first turntable 18, thereby driving the second large pulley 21 to rotate, and rotates the second small pulley 2401 through the belt, so that the fan blades 24 rotate synchronously.

[0063] Through the acceleration effect 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 blade 24 is much greater than the rotation speed of the main shaft 4.

[0064] Afterwards, when the main shaft 4 rotates, the fan blades 24 will rotate rapidly to accelerate the air in the mixing barrel 2 to flow into the air collecting tank 32 to collect the suspended sample powder.

[0065] When the fan blade 24 rotates, the screw column 401 is still rotating, thereby driving the internal threaded sleeve 22 to move. At this time, the blocking rod 23 is blocked by the connecting rod 15, so the internal threaded sleeve 22 compresses the third spring 34.

[0066] The air in the mixing barrel 2 quickly enters the gas collecting tank 32 through the air inlet pipe 3201. Under the action of centrifugal force and airflow, the sample powder will spiral downward close to the inner wall of the gas collecting tank 32 and gather on the conical pipe 3202. It will be discharged from the outlet end of the conical pipe 3202, and the air will be discharged outward from the exhaust pipe 3203.

[0067] 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 between the gaps between samples).

[0068] Through the cooperation between the blowing structure and the gas collecting tank 32, the sample powder suspended on the mixing barrel 2 and the discharge port 202 can be collected faster, thus avoiding errors in the test results caused by incomplete samples and improving the test efficiency.

[0069] In another embodiment of the present invention, a rotating block 29 is rotatably sealed and installed on the air intake duct 3201; an opening and closing inclined groove 2901 is provided on the rotating block 29; a plurality of sets of mutually cooperating guide plates 30 are rotatably installed on the circumference of the air intake duct 3201; a third protruding column 3001 which is slidably engaged with the rotating block 29 is fixedly installed on the guide plate 30.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] Then, the second protruding column 2501 will slide in the second straight groove 2603, and the second rotating shaft 26 will not rotate to maintain the conducting state. During this process, the fan blade 24 will continue to rotate.

[0078] In another embodiment of the present invention, the air intake pipe 3201 is located in the tangential direction of the air collecting tank 32; and the exhaust pipe 3203 is vertically installed in the middle of the air collecting tank 32, and one end is connected to the outside.

[0079] Taking the embodiment combining all the features described in the present application as an example, when in use, the air inlet pipe 3201 is located tangentially to the air collecting tank 32, so that after the air flow enters the air collecting tank 32 from the air inlet pipe 3201, it will flow along the circumference of the air collecting tank 32, and under the action of gravity, the air flow will spirally flow toward the lower end; during this process, the sample powder will move downward in a spiral.

[0080] When the airflow reaches the end of the flow, an internal vortex is formed, so that it can be discharged outward through the exhaust pipe 3203. The powder is discharged onto the carrier plate 13 along the tapered pipe 3202.

[0081] In another embodiment of the present invention, a baffle 402 is fixedly mounted on the main shaft 4; a return spring 31 is wrapped around the main shaft 4; and two ends of the return spring 31 are in contact with the baffle 402 and the first large pulley 14 respectively.

[0082] Taking the embodiment combining all the features described in the present application as an example, when in use, the return spring 31 will be compressed during the process of the first rotating disk 18 approaching the second rotating disk 19 .

[0083] During the resetting process, the elastic force of the resetting spring 31 drives the first large pulley 14 to reset, thereby separating the first rotating disk 18 from the second rotating disk 19 and resetting.

[0084] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0085] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
