Description

Technical Field

[0001] This utility model relates to the field of liquid feed additive preparation technology, specifically a livestock and poultry additive testing and sampling device. Background Technology

[0002] In the preparation of immune-enhancing mixed feed additives for livestock and poultry, the production process of feed additives in solution form requires continuous quality testing of the product to check whether the content of various components meets the standards. It is necessary to take a representative sample from a large number of additive products, so a testing and sampling device is required.

[0003] A Chinese patent with authorization announcement number CN117388006A discloses a sampling device for the production of liquid feed additives, including a rectangular hole; a first side hole is opened on the side wall of the rectangular hole; an electric push cylinder is fixedly connected to the bottom of the first side hole; a baffle is fixedly connected to the end of the electric push cylinder; a flow meter is fixedly connected to the bottom of the baffle; the baffle is slidably connected in the first side hole; a shell is fixedly connected to the outer surface of the tank; an inclined outlet is opened at the junction of the shell and the rectangular hole; the rectangular hole is blocked by the baffle; during sampling, the electric push cylinder retracts, pulling up the baffle, and the liquid feed flows out through the inclined outlet; when the sampling is finished, the electric push cylinder pushes the baffle back to seal the rectangular opening, so that it is not necessary to open the feed port of the reaction vessel when extracting liquid feed, reducing the harm to people caused by the high pressure gas that may exist inside.

[0004] However, the above-mentioned sampling device still has some problems. In practical applications, it cannot achieve quantitative sampling, and the amount of each sample is not fixed. When analyzing the composition of liquid feed additives, the test results may not accurately reflect the true content of the additives, and it may not be possible to correctly determine whether the additives meet the quality standards. Therefore, a livestock and poultry additive testing sampling device is proposed to address the above problems. Utility Model Content

An electrode plate is installed on one side of the connecting block. An electrode sheet is installed on one side of the piston plate. An indicator light is installed on one side of the connecting plate. Through the coordinated work of the piston plate, connecting rod, and cylinder, combined with the scale rod and locking screw, precise quantitative sampling of the mixed liquid feed additive can be achieved.

[0007] Preferably, a valve is installed on the outer side of one end of the conveying pipe, an output pipe is installed on the bottom side of one end of the sampling cylinder, and a valve is installed inside the output pipe. The valve on the conveying pipe controls the feeding, and the valve on the output pipe at the bottom of the sampling cylinder controls the discharging, which facilitates sampling operations and subsequent testing.

[0008] Preferably, the top side of the mixing tank is connected to a feed pipe, the bottom side of the mixing tank is connected to a discharge pipe, and the discharge pipe is equipped with a discharge valve to facilitate the mixing and discharge of feed additives.

[0009] Preferably, a stirring motor is installed on the top side of the mixing tank, a rotating shaft is installed at the output end of the stirring motor, a scraper is installed at the top of the rotating shaft, the scraper is in contact with the inner wall of the mixing tank, and three stirring rods are installed at equal intervals on the outer side of the rotating shaft, one end of each stirring rod is installed on the inner side of the scraper. The stirring motor drives the rotating shaft and the scraper to rotate, the scraper contacts the inner wall of the mixing tank, and the stirring rods are installed on the rotating shaft to ensure that the feed additives are mixed evenly and to scrape off the residue on the tank wall.

[0010] Preferably, four mounting frames are equidistantly installed on the outer side of the rotating shaft. A driving bevel gear is installed inside each mounting frame on the outer side of the rotating shaft. A rotating shaft is rotatably installed through one side of each mounting frame. A driven bevel gear is installed at one end of the rotating shaft inside the mounting frame. The driving bevel gear and the driven bevel gear mesh with each other. Three sets of three stirring blades are installed at the other end of the rotating shaft. Through gear transmission, multiple stirring blades stir in different areas inside the mixing tank, further improving the mixing uniformity and thus improving the accuracy of sampling tests.

[0011] Preferably, four support legs are equidistantly installed on the bottom side of the mixing tank, and a control panel is installed on the outside of the mixing tank.

In addition, the active bevel gear on the rotating shaft rotates, which drives the driven bevel gear through meshing, causing the rotating shaft to rotate. This allows the stirring blades to stir in different areas of the tank, improving the uniformity of mixing and laying the foundation for accurate sampling and testing. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figure 1-3 As shown, a sampling device for testing livestock and poultry additives includes a mixing tank 1. A conveying pipe 2 is connected to one side of the bottom of the mixing tank 1. A sampling cylinder 3 is connected to one side of the conveying pipe 2. A connecting rod 4 is slidably installed inside one end of the sampling cylinder 3. A piston plate 5 is installed at one end of the connecting rod 4. The outer diameter of the piston plate 5 is equal to the inner diameter of the sampling cylinder 3. A connecting plate 6 is installed at the other end of the connecting rod 4. A cylinder 7 is installed on the outside of the mixing tank 1. The working end of the cylinder 7 is installed on one side of the top of the connecting plate 6. A limiting ring 8 is installed on one side of the sampling cylinder 3. A scale rod 9 is slidably installed inside the limiting ring 8, extending into the sampling cylinder 3. A locking screw 10 is rotatably installed inside the limiting ring 8. One end of the locking screw 10 abuts against the scale rod 9. A connecting block 11 is installed at one end of the scale rod 9. An electrode plate 12 is installed on one side of the connecting block 11. An electrode sheet 13 is installed on one side of the piston plate 5. An indicator light 14 is installed on one side of the connecting plate 6. A valve 15 is installed on the outer side of one end of the delivery pipe 2, and an output pipe 16 is installed on the bottom side of one end of the sampling cylinder 3. A valve 17 is installed inside the output pipe 16. Four support legs 30 are equidistantly installed on the bottom side of the mixing tank 1. A control panel 31 is installed on the outside of the mixing tank 1. The electrode plate 12, electrode sheet 13, indicator light 14, and power supply are connected in a circuit. The indicator light 14 is connected to the control panel 31 through a signal line. The control panel 31 is used to control the operation of the internal electrical components of the device and to close the cylinder 7. In actual application, quantitative sampling cannot be achieved during operation. The amount of each sample is not fixed. When analyzing the components of liquid feed additives, the test results may not accurately reflect the true component content of the additives, and it may be impossible to correctly determine whether the additives meet the quality standards. The sampling cylinder 3 is transparent. When sampling, first loosen the locking screw 10 inside the limiting ring 8 to release the fixation of the scale rod 9. The scale rod 9 can slide inside the limiting ring 8 and the sampling cylinder 3. The electrode plate 12 will also move together. By observing the scale on the scale rod 9, the electrode plate is... 12 moves to a position where the distance between it and electrode 13 is the required sampling amount of liquid feed additive. Then, the locking screw 10 is rotated so that one end of it abuts against the scale rod 9, thereby fixing the position of the scale rod 9. After determining the sampling amount, valve 15 and cylinder 7 are activated. The working end of cylinder 7 extends and pushes the connecting plate 6, so the connecting rod 4 moves with the connecting plate 6. As the connecting rod 4 moves, the piston plate 5 moves inside the sampling cylinder 3. At this time, the liquid in the mixing tank 1 enters the sampling cylinder 3 through the delivery pipe 2 under the pressure difference generated by the movement of the piston plate 5. When the piston plate 5 moves to contact the electrode plate 12, the electrode plate 12 and electrode 13 are connected to the circuit. At this time, the indicator light 14 lights up and transmits the signal to the control panel 31 through the signal line. At the same time, the control panel 31 receives the signal and controls the cylinder 7 to close, completing a quantitative sampling and realizing accurate quantitative sampling of the mixed liquid feed additive. After sampling is completed, open valve 17 inside the output tube 16. A fixed amount of liquid feed additive in the sampling cylinder 3 can be discharged through the output tube 16 for subsequent tests to evaluate the quality and performance of the immune-enhancing mixed feed additive for livestock and poultry.

[0018] Please see Figure 1 , 2 As shown in Figures 4 and 5, the top side of the mixing tank 1 is connected to a feed pipe 18, the bottom side of the mixing tank 1 is connected to a discharge pipe 19, and a discharge valve 20 is installed inside the discharge pipe 19. A stirring motor 21 is installed on the top side of the mixing tank 1. A rotating shaft 22 is installed at the output end of the stirring motor 21. A scraper 23 is installed at the top of the rotating shaft 22. The scraper 23 is in contact with the inner wall of the mixing tank 1. Three stirring rods 24 are installed at equal intervals on the outer side of the rotating shaft 22. One end of each stirring rod 24 is installed on the inner side of the scraper 23. Four mounting frames 25 are equidistantly installed on the outer side of the rotating shaft 22. A driving bevel gear 26 is installed inside each mounting frame 25 on the outer side of the rotating shaft 22. A rotating shaft 27 is rotatably mounted through one side of each mounting frame 25. A driven bevel gear 28 is installed at one end of the rotating shaft 27 inside the mounting frame 25. The driving bevel gear 26 and the driven bevel gear 28 mesh with each other. Three sets of stirring blades 29 are installed at the other end of the rotating shaft 27. During operation, in the production process of the solution-state feed additive, continuous quality testing of the product is required to check whether the content of various components meets the standards. A representative sample needs to be taken from a large number of additive products; therefore, a testing and sampling device is required. When preparing immune-enhancing mixed feed additives for livestock and poultry, various raw materials are first added to the mixing tank 1 through the feed pipe 18. At this time, the discharge valve 20 inside the discharge pipe 19 is closed to prevent premature discharge of raw materials. Subsequently... When the stirring motor 21 is started, its output drives the rotating shaft 22 to rotate. The scraper 23 rotates along with the rotating shaft 22. Since the scraper 23 is in contact with the inner wall of the mixing tank 1, it can scrape off the additive raw materials adhering to the inner wall of the mixing tank 1, preventing raw material residue and ensuring sufficient mixing. At the same time, the stirring rod 24 also rotates along with the rotating shaft 22. During the rotation, the stirring rod 24 continuously agitates the liquid in the mixing tank 1, mixing the liquids of different components. In addition, the driving bevel gear 26 rotates synchronously with the rotating shaft 22. Since the driving bevel gear 26 and the driven bevel gear 28 mesh with each other, when the driving bevel gear 26 rotates, it will drive the driven bevel gear 28 to rotate. The driven bevel gear 28 is installed at one end of the rotating shaft 27, so the rotating shaft 27 will also rotate. Therefore, the stirring blade 29 stirs in different areas inside the mixing tank 1, further improving the mixing uniformity and ensuring that various components can be fully mixed, providing a guarantee for subsequent accurate sampling and testing. Once mixing is complete, open the discharge valve 20, and the mixed liquid feed additive can be discharged through the discharge pipe 19 for subsequent packaging or other processes.

[0019] Working principle: When preparing immune-enhancing mixed feed additives for livestock and poultry, various raw materials are first added to the mixing tank 1 through the feed pipe 18. At this time, the discharge valve 20 inside the discharge pipe 19 is closed to prevent the raw materials from flowing out prematurely. Then, the stirring motor 21 is started. The output end of the stirring motor 21 drives the rotating shaft 22 to start rotating. The scraper 23 rotates together with the rotating shaft 22. Since the scraper 23 is in contact with the inner wall of the mixing tank 1, it can scrape off the additive raw materials adhering to the inner wall of the mixing tank 1, preventing raw material residue and ensuring sufficient mixing. At the same time, the stirring rod 24 also rotates together with the rotating shaft 22. During rotation, the stirring rod 24 continuously agitates the liquid in the mixing tank 1, mixing the liquids of different components. In addition, the driving bevel gear 26 rotates synchronously with the rotating shaft 22. Since the driving bevel gear 26 and the driven bevel gear 28 mesh with each other, when the driving bevel gear 26 rotates, it will drive the driven bevel gear 28 to rotate. The driven bevel gear 28 is installed at one end of the rotating shaft 27, so the rotating shaft 27 will also rotate. Therefore, the stirring blade 29 stirs in different areas inside the mixing tank 1, further improving the mixing uniformity and ensuring that various components can be fully mixed, providing a guarantee for accurate sampling and testing in the future. Once mixing is complete, open the discharge valve 20, and the mixed liquid feed additive can be discharged through the discharge pipe 19 for subsequent packaging or other processes. Sampling cylinder 3 is transparent. During sampling, first loosen the locking screw 10 inside the limiting ring 8 to release the fixation of the scale rod 9. The scale rod 9 can slide inside the limiting ring 8 and sampling cylinder 3, and the electrode plate 12 will also move. By observing the scale on the scale rod 9, move the electrode plate 12 to a position where the distance between it and the electrode plate 13 is the required sampling amount of liquid feed additive. Then, rotate the locking screw 10 so that one end abuts against the scale rod 9, thus fixing the position of the scale rod 9. After determining the sampling amount, activate valve 15 and cylinder 7. The working end of cylinder 7 extends, pushing the connecting plate. 6. Therefore, the connecting rod 4 will move together with the connecting plate 6. As the connecting rod 4 moves, the piston plate 5 moves inside the sampling cylinder 3. At this time, the liquid in the mixing tank 1 enters the sampling cylinder 3 through the delivery pipe 2 under the pressure difference generated by the movement of the piston plate 5. When the piston plate 5 moves to contact the electrode plate 12, the electrode plate 12 and the electrode sheet 13 are connected to the circuit. At this time, the indicator light 14 lights up and transmits the signal to the control panel 31 through the signal line. At the same time, the control panel 31 receives the signal and controls the cylinder 7 to close, completing a quantitative sampling and realizing accurate quantitative sampling of the mixed liquid feed additive. After sampling is completed, open valve 17 inside the output tube 16. A fixed amount of liquid feed additive in the sampling cylinder 3 can be discharged through the output tube 16 for subsequent tests to evaluate the quality and performance of the immune-enhancing mixed feed additive for livestock and poultry.
