Description

Technical Field

[0001] The present application relates to the technical field of feed additive production, and in particular to a sampling and detection device for feed additives that promote intestinal health of livestock and poultry. Background Art

[0002] Currently, an increasing number of adverse factors are threatening the health of livestock and poultry, leading to the occurrence of diseases. Once livestock and poultry become ill, their production efficiency is reduced. Therefore, ensuring livestock and poultry health is a prerequisite for efficient production. The intestine is a vital component of the animal body. Intestinal health determines the overall function and productivity of livestock and poultry. Improving intestinal structure and function is crucial for the development of healthy livestock and poultry farming. A stable intestinal environment, intact intestinal structure, and a relatively balanced intestinal microbiome are the foundations of a healthy animal's gut. The intestine, through its unique structure, separates various intestinal substances from the animal's internal environment, effectively digesting and absorbing nutrients while preventing the invasion of harmful substances within the intestinal lumen. Complex regulatory mechanisms and signaling pathways between the various intestinal mucosal barriers form a defensive barrier, jointly combating the invasion of harmful substances such as bacteria and viruses. Through this mucosal barrier, the intestine effectively prevents harmful substances such as bacteria and endotoxins from entering the tissues or blood circulation of poultry, thereby protecting the healthy growth of livestock and poultry. However, under adverse external conditions (such as heat stress, harmful gas stimulation, nutrient deficiency, etc.), intestinal microorganisms and endotoxins break through the intestinal barrier, leading to intestinal mucosal lesions, reduced digestive enzyme activity, and microbial flora disorders, which seriously endanger the health and production performance of livestock and poultry.

[0003] In the related art, a Chinese patent with publication number CN108077600A proposes a sampling and detection device for a feed additive that promotes intestinal health in livestock and poultry, using cetylpyridinium chloride to modify montmorillonite to load carvacrol. The montmorillonite modified by cetylpyridinium chloride increases the interlayer spacing, specific surface area and hydrophobicity of the montmorillonite, greatly enhancing the adsorption rate of carvacrol. Montmorillonite has excellent biocompatibility and affinity for the gastrointestinal mucosa, and has a controlled release effect on the loaded carvacrol, which can more effectively exert the antibacterial, anti-inflammatory, and antioxidant effects of carvacrol, and has a combined synergistic and synergistic effect on antibacterial activity. The feed additive of the present invention has the characteristics of strong antibacterial effect and low resistance to drug resistance of bacteria. It can effectively inhibit the proliferation of harmful bacteria in the intestinal tract of livestock and poultry, increase the height of intestinal villi and intestinal barrier function, benefit the secretion of digestive enzymes and the digestion of feed nutrients, promote the intestinal health of livestock and poultry, and improve the production performance of livestock and poultry.

[0004] Regarding the above-mentioned related technologies, the inventors believe that there are the following defects: in the process of producing feed additives that promote intestinal health of livestock and poultry, the final filter cake needs to be dried. If it contains moisture, it will cause problems with the powder obtained in the subsequent crushing process, such as agglomeration. However, since the filter cake is a layered solid, when it is dried, its surface is dried while its interior is not dried. Summary of the Invention

After sampling is completed, rotate the sampling cylinder so that the opening is facing upwards, that is, facing the squeezing plate, pull the test paper to the bottom of the filter, and squeeze out water from the sample in the sampling cylinder by controlling the squeezing rod and the squeezing plate.

When the two drying half rings are combined together, the two magnet blocks attract each other, thereby achieving the effect of combining the drying half rings and connecting the scraper to the drying half ring. Since the thickness of the drying half ring is larger than the thickness of the scraper, the heating element in the drying half ring dries the sample on the scraper's movement path. Turn on a power supply so that the power flows on the two guide rails and the slide rod. The two guide rails, the slide rod and the external DC power supply form a closed loop. According to the direction of current flow and Ampere's law, the direction of the magnetic flux lines within the range of the two guide rails and the slide rod close to the energized power supply side can be obtained. Then, by the left-hand rule, the direction of the Ampere force on the slide rod is parallel to the guide rail and points to the opening of the sampling tube. That is, when the guide rail is energized, the slide rod is acted upon by the Ampere force and moves on the guide rail toward the opening of the sampling tube, thereby driving the slide rod and the scraper to move. The dried sample is convenient for the scraper to scrape, thereby ensuring the cleanliness of the sampling tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1-5 This application is described in further detail. Example 1

[0036] The present application discloses a sampling and detection device for feed additives that promote intestinal health of livestock and poultry. Figure 1-Figure 5 A method for preparing a feed additive for promoting intestinal health of livestock and poultry comprises the following steps:

[0037] S1. Add water to montmorillonite and sodium chloride and stir evenly to prepare a suspension slurry with a concentration of 10% to 20%, sodiumize at room temperature, and re-form the slurry with a concentration of 15% to 40% with water;

[0038] S2. Slowly add cetylpyridinium chloride to the ore slurry in step S1 under stirring, and continue stirring at room temperature for a certain time;

[0039] S3. Slowly add carvacrol to the slurry from step S2 under stirring, and continue stirring at room temperature for a certain period of time;

[0040] S4, dehydrating the reaction solution in step S3 and drying the resulting filter cake; after drying, the interior of the filter cake needs to be inspected to see if it is completely dried;

[0041] Reference Figure 1-Figure 3 , S5, crushing, to obtain a feed additive that promotes intestinal health of livestock and poultry; in S4, the inside of the filter cake is sampled and tested by a detection device, the detection device includes a sampling inspection mechanism, a testing mechanism for testing whether there is water, and a cleaning mechanism for cleaning the sampling inspection mechanism; the sampling inspection mechanism includes a frame 1, a bracket 2 that is lifted and lowered on the frame 1, a sampling inspection cylinder 3 that is rotatably arranged on the bracket 2, and a rotating component for controlling the rotation of the sampling inspection cylinder 3, the bottom end of the sampling inspection cylinder 3 is open, and the other end is closed. The length of the sampling inspection cylinder 3 is greater than the thickness of the filter cake. After the length of the sampling inspection cylinder 3 is greater than the filter cake, the sampling inspection cylinder 3 can take samples from all positions of the center of the filter cake, thereby not only performing a dry inspection on the surface of the filter cake, but also performing a clean inspection on the inside of the filter cake. When drying test is carried out, the inspection cylinder 3 is opened downward in the initial state and is facing the center of the filter cake. The lifting and lowering of the bracket 2 is achieved by an electric push rod or a cylinder. The rotating assembly is controlled by a rotating motor 4. The inspection cylinder 3 and the bracket 2 are rotatably connected with a rotating shaft. The output end of the rotating motor 4 is connected to the end of the rotating shaft. The rotating shaft is located at the end of the inspection cylinder 3 close to the bottom end. First, the inspection cylinder 3 is rotated to the position where the opening is facing downward, and the bracket 2 moves downward. When the inspection cylinder 3 moves toward the filter cake, the sample enters the inspection cylinder 3. When the inspection cylinder 3 moves to the bottom end of the filter cake, the bracket 2 and the inspection cylinder 3 are moved upward until they are separated from the filter cake. The rotating motor 4 is then used to control the rotation of the inspection cylinder 3, and the open end of the inspection cylinder 3 is rotated upward to complete the sampling work.

[0042] The testing mechanism includes an extrusion cylinder 5, an extrusion frame 6 rotatably arranged on the bracket 2, an extrusion rod 7 lifted and arranged on the extrusion frame 6, an extrusion disk 8 fixed at the bottom end of the extrusion rod 7 and an identification component arranged in the extrusion cylinder 5. One end of the extrusion cylinder 5 is open and connected to the open end of the sampling cylinder 3. A filter screen 9 is fixedly connected to the opening of the extrusion cylinder 5. The filter screen 9 is used to block the sample from entering the extrusion cylinder 5 and ensure that water can enter the extrusion cylinder 5. Similarly, an outlet is provided at the bottom end of the extrusion cylinder 5, and an electromagnetic valve is provided at the outlet. When the test is completed, the water in the extrusion cylinder 5 needs to be released. The extrusion frame 6 is located above the sampling cylinder 3. The rotation of the extrusion frame 6 is realized by the extrusion motor, and the lifting of the extrusion rod 7 can be realized by an electric push rod or a cylinder. The extrusion disk 8 is adapted to the shape of the sampling cylinder 3, and can then enter the extrusion cylinder 5 and squeeze out water from the sample in the extrusion cylinder 5. The identification component is used to detect whether there is water in the sample.

[0043] Reference Figure 1-Figure 3 The identification component includes a test paper 10, a winding portion for winding the test paper 10, a color sensor 14, and a buzzer 15 electrically connected to the color sensor 14. The test paper 10 is movably arranged in the extrusion cylinder 5. The color sensor 14 is opposite to the test paper 10 and close to the bottom wall of the extrusion cylinder 5. The area of ​​the test paper 10 is larger than the area of ​​the filter 9 so that the squeezed water can fall onto the test paper 10. The winding portion includes two winding motors 12, multiple winding ropes 11 and two winding rollers 13. The winding rollers 13 are respectively located on both sides of the extrusion cylinder 5. The winding motor 12 is used to control the rotation of the winding rollers 13. In this embodiment, the test paper 10 uses cobaltous chloride test paper. The cobaltous chloride test paper turns red when it comes into contact with water, and thus it can be judged whether there is water in the sample. Multiple winding ropes 11 and multiple test papers 10 are arranged at intervals. When the extrusion cylinder 5 starts to release water, the winding rope 11 is located in the extrusion cylinder 5. When testing is required, the test paper 10 is located in the extrusion cylinder 5. The color sensor 14 and the buzzer 15 are controlled and connected by a PLC controller; when sampling is completed, the sampling cylinder 3 is rotated so that the opening is facing upward, that is, facing the extrusion disk 8, and the test paper 10 is pulled to the bottom of the filter screen 9. The sample in the sampling cylinder 3 is squeezed out of water by controlling the extrusion rod 7 and the extrusion disk 8. If the sample is not dried, the water is squeezed into the extrusion cylinder 5 at this time, and the test paper 10 changes color after encountering water. The color sensor 14 recognizes that the test paper 10 has changed color, and the color sensor 14 triggers the buzzer 15 to make a sound, proving that the filter cake is not dried.

[0044] The testing mechanism also includes a testing rod 16 slidably arranged on the frame 1, an absorbent paper 17 fixedly sleeved on the end of the testing rod 16, and a reciprocating part for realizing the reciprocating movement of the testing rod 16. The movement direction of the testing rod 16 is along the horizontal direction. The side wall of the sampling tube 3 is provided with a testing hole 18 adapted to the testing rod 16. When the sampling tube 3 is rotated to the opening facing upward, the testing rod 16 is opposite to the testing hole 18. In the initial position, the testing rod 16 is away from the position of the sampling tube 3, thereby preventing the testing rod 16 from affecting the normal operation of the sampling tube 3. In this embodiment, the absorbent paper 17 can of course also use the detection principle of the cobaltous chloride test paper 10 and the color sensor 14. However, the main function of the absorbent paper 17 in this embodiment is to squeeze out water from the filter cake, but its interior is in a moist state. At this time, when the sample is pressed in the sampling tube 3, the absorbent paper 17 can still absorb water for the moist sample. The color depth of the absorbent paper 17 is different in the dry and moist states, and only the staff needs to observe.

[0045] The reciprocating part includes a reciprocating electric push rod 28, which is used to control the movement of the test rod 16. When the sampling tube 3 completes sampling and the sampling tube 3 is rotated to the position where the opening is facing upward, the end of the test rod 16 is facing the test hole 18, and the reciprocating electric push rod 28 moves the test rod 16 toward the test hole 18. The test rod 16 moves into the test hole 18 and the test rod 16 does not extend out of the test hole 18, and the absorbent paper 17 can just abut against the sample, and the test rod 16 can also seal the test hole 18 to prevent water from being squeezed out of the test hole 18. When the sample starts to be squeezed, the absorbent paper 17 on the test rod 16 is always in contact with the sample. As samples at different positions are squeezed, the absorbent paper 17 contacts samples at different positions, and then the absorbent paper 17 can fully contact the wet sample to determine whether the sample is wet, thereby greatly improving the detection accuracy.

[0046] Reference Figure 1-Figure 3The cleaning mechanism includes a loosening component for breaking up the sample after extrusion, a drying component for drying the sample, and a scraper component for cleaning the inner wall of the sampling tube 3. The loosening component includes a loosening frame 19 that is lifted and lowered on the extrusion frame 6, a loosening motor 20 fixed on the loosening frame 19, and a loosening leaf 21 that is rotatably arranged on the loosening frame 19. The loosening motor 20 controls the rotation of the loosening leaf 21. The loosening frame 19 and the extrusion rod 7 are respectively located at the two ends of the extrusion frame 6. The lifting of the loosening frame 19 is also achieved by an electric push rod or a cylinder. The loosening leaf 21 adopts a spiral shape in this embodiment to facilitate the extrusion. After the sample is broken up, when the test is completed, the extrusion frame 6 is controlled to rotate. After the extrusion motor controls the extrusion frame 6 to rotate 180°, the loosening leaf 21 is opposite to the opening of the sampling tube 3. The opening size of the sampling tube 3 is larger than the size of the loosening leaf 21. At this time, the loosening frame 19 is controlled to descend and the loosening leaf 21 moves into the sampling tube 3. The loosening motor 20 controls the loosening leaf 21 to rotate and breaks up the sample in the sampling tube 3. At this time, it is convenient for the sample to fall from the sampling tube 3. After the loosening leaf 21 is moved to a position away from the sampling tube 3, the sampling tube 3 is controlled to rotate and the opening of the sampling tube 3 is facing downward, and the sample falls from the sampling tube 3.

[0047] The scraper assembly includes a scraper 22 slidably arranged in the sampling tube 3 and a driving part that controls the reciprocating movement of the scraper 22. The scraper 22 is located close to the extrusion tube 5 in the initial state. The driving part includes two guide rails 23 and a slide rod 24. The two guide rails 23 are respectively fixed at two opposite positions in the sampling tube 3. The two ends of the slide rod 24 are respectively sleeved and slid on the two guide rails 23. The guide rails 23 and the slide rod 24 are made of conductive material, and the two guide rails 23 are respectively connected to the external power supply with opposite positive and negative poles. The scraper 22 is set to be annular, and the slide rod 24 is also set to be arc-shaped. The thickness of the scraper 22 gradually decreases towards the inside of the sampling tube 3, so that the inner wall of the sampling tube 3 can be scraped for sampling. Since the guide rails 23 and the slide rod 24 are both located in the sampling tube 3, the scraper 22 and the extrusion disk 8 are both selected to have corresponding shapes so as to fully adapt to the inner wall of the sampling tube 3.

[0048] In this embodiment, a positive and negative power supply is connected to the same end of the two guide rails 23, and then another positive and negative power supply is connected to the other end of the guide rail 23, and the two ends of the same guide rail 23 are respectively connected to power supplies of different electrodes, thereby realizing the reciprocating motion of the slide bar 24. In the initial state, the scraper 22 is located close to the extrusion cylinder 5, so that the scraper 22 is located above the sampling cylinder 3 when unloading. When the scraper 22 needs to move, a power supply is turned on at this time, so that the power flows on the two guide rails 23 and the slide bar 24. The two guide rails 23, the slide bar 24 and the external DC power supply form a closed loop. According to the direction of the current flow and the installation By the left-hand rule, the direction of the magnetic flux lines of the two guide rails 23 and the slide bar 24 within the range of the energized power supply side can be obtained. Then, by the left-hand rule, the direction of the Ampere force on the slide bar 24 is parallel to the guide rail 23 and points to the opening of the sampling tube 3. That is, when the guide rail 23 is energized, the slide bar 24 is acted upon by the Ampere force and moves on the guide rail 23 toward the opening of the sampling tube 3, thereby driving the slide bar 24 and the scraper 22 to move. When the scraper 22 needs to move to the initial position, this power supply can be turned off and another power supply can be turned on. At this time, the movement direction of the slide bar 24 is in the direction away from the extrusion tube 5, thereby moving the scraper 22 to the initial position.

[0049] Reference Figure 1-Figure 5 The drying assembly includes two drying half rings 25, a heating element 26, a control unit for controlling the movement of the drying half rings 25, and a connection unit for connecting the drying half rings 25 and the slide bar 24. The two drying half rings 25 are adapted to the sampling tube 3. The heating element 26 is arranged in the drying half ring 25. The thickness of the drying half ring 25 is greater than the thickness of the scraper 22. The two drying half rings 25 are adsorbed by two first electromagnets 31. The heating element 26 can be selected from electric heating wires in this embodiment. The control unit includes a control electric push rod 27 and a second electromagnet 32. The second electromagnet 32 ​​is connected to the pair of The drying half ring 25 should be adsorbed, and the drying half ring 25 is slidably set on the frame 1. Therefore, the drying half ring 25 is also away from the movement route of the sampling tube 3 in the initial position to avoid affecting the normal operation of the sampling tube 3. When the drying half ring 25 needs to be dried, the electric push rod 27 is controlled to move the drying half ring 25 toward the sampling tube 3. When the two drying half rings 25 abut, the two drying half rings 25 adapt to the outer wall of the sampling tube 3. After the drying half rings 25 are in contact, the first electromagnet 31 is energized and the second electromagnet 32 ​​is de-energized. At this time, the two drying half rings 25 are combined together.

[0050] The connecting part includes two magnet blocks 29 and a partition 30. The magnet block 29 is fixed in the sliding rod 24. The sampling tube 3 is provided with a partition for installing the partition 30. The other magnet block 29 is fixed to the inner wall of any drying semi-ring 25. The two magnet blocks 29 are respectively located on both sides of the partition 30 and adsorbed to each other. The drying semi-ring 25 moves together with the scraper 22. The partition 30 is made of a material that facilitates the mutual adsorption of the two magnet blocks 29. The corresponding drying semi-ring 25 is provided with a mounting hole, and the corresponding magnet block 29 is installed in the mounting hole. When the two drying semi-rings 25 are combined together, the two magnet blocks 29 adsorb each other, thereby achieving the effect of combining the drying semi-rings 25 and connecting the scraper 22 to the drying semi-ring 25. Since the thickness of the drying semi-ring 25 is greater than the thickness of the scraper 22, the heating element 26 in the drying semi-ring 25 dries the sample on the movement path of the scraper 22. The dried sample is convenient for the scraper 22 to scrape, thereby ensuring the cleanliness of the sampling tube 3.

[0051] The implementation principle of the sampling and detection device for feed additives that promote intestinal health of livestock and poultry in the embodiment of the present application is as follows: first, the sampling tube 3 is rotated to a position where the opening is facing downward, and the bracket 2 is moved downward. When the sampling tube 3 moves toward the filter cake, the sample enters the sampling tube 3. When the sampling tube 3 moves to the bottom end of the filter cake, the bracket 2 and the sampling tube 3 are moved upward until they are separated from the filter cake. Then, the rotating motor 4 is used to control the rotation of the sampling tube 3, and the open end of the sampling tube 3 is rotated upward to complete the sampling work.

[0052] When the sampling is completed, the sampling cylinder 3 is rotated to the point where the opening is facing upwards, that is, facing the squeezing plate 8, and the test paper 10 is pulled under the filter screen 9. The sample in the sampling cylinder 3 is squeezed out of water by controlling the squeezing rod 7 and the squeezing plate 8. If the sample is not dried, the water is squeezed into the squeezing cylinder 5, and the test paper 10 changes color after encountering the water. The color sensor 14 recognizes that the test paper 10 has changed color, and the color sensor 14 triggers the buzzer 15 to sound, proving that the filter cake is not dried; the test rod 16 moves to the test hole 18 and the test is carried out. The test rod 16 does not extend out of the test hole 18, and the absorbent paper 17 can just contact the sample. The test rod 16 can also block the test hole 18 to prevent water from being squeezed out of the test hole 18. When the sample begins to be squeezed, the absorbent paper 17 on the test rod 16 is always in contact with the sample. As the sample at different positions is squeezed, the absorbent paper 17 contacts the sample at different positions. Then, the absorbent paper 17 can fully contact the wet sample and be used to determine whether the sample is wet, greatly improving the detection accuracy.

[0053] When the two drying half rings 25 are combined together, the two magnet blocks 29 attract each other, thereby achieving the effect of combining the drying half rings 25 and connecting the scraper 22 to the drying half ring 25. Since the thickness of the drying half ring 25 is greater than the thickness of the scraper 22, the heating element 26 in the drying half ring 25 dries the sample on the movement path of the scraper 22. A power supply is turned on, so that the power flows on the two guide rails 23 and the slide rod 24. The two guide rails 23, the slide rod 24 and the external DC power supply form a closed loop. According to the direction of current flow and Ampere's law, the direction of the magnetic flux lines of the two guide rails 23 and the slide bar 24 within the range of the energized power supply side can be obtained. Then, through the left-hand rule, it can be obtained that the direction of the Ampere force exerted on the slide bar 24 is parallel to the guide rail 23 and points to the opening of the sampling tube 3. That is, when the guide rail 23 is energized, the slide bar 24 is acted upon by the Ampere force and moves on the guide rail 23 toward the opening of the sampling tube 3, thereby driving the slide bar 24 and the scraper 22 to move. The dried sample is convenient for the scraper 22 to scrape, thereby ensuring that the inside of the sampling tube 3 is clean. Example 2

[0054] The present application discloses a feed additive that promotes intestinal health of livestock and poultry. Figure 1 A feed additive for promoting intestinal health of livestock and poultry includes montmorillonite, sodium chloride and cetylpyridinium chloride. The feed additive for promoting intestinal health of livestock and poultry is obtained by the above components. When 0.1% (mass percentage) of the feed additive for promoting intestinal health of livestock and poultry is added to the diet of laying hens, the egg production rate of laying hens can be increased by 1.5 percentage points, spotted eggs can be effectively controlled, the eggshell smoothness can be improved, and the qualified egg rate can be increased by 2 percentage points. The results of intestinal microecology and intestinal morphology analysis show that the addition of 0.1% of the feed additive for promoting intestinal health of livestock and poultry can reduce the number of Escherichia coli and Clostridium perfringens in the contents of the small intestine and cecum, and significantly increase the ratio of villus height to crypt depth in the duodenum, jejunum and ileum (P<0.05).

[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
