[0002] Compound premixes for pigs are formed by mixing various trace components such as vitamins, minerals, amino acids, etc. with carriers in a certain proportion. In modern pig farming, compound premixes, as key inputs to improve pig growth performance, enhance immunity, and optimize feed utilization rate, their quality and safety are directly related to pig growth and development, production performance, breeding efficiency, and food safety.

The top of the sampling box is open. A sampling opening is formed in the side of the conveying pipeline corresponding to the sampling box. A clamping hole is formed in the side of the mounting seat and located in the upper part of the side of the sampling box. A baffle plate for blocking and sealing the sampling opening is slidably arranged in the clamping hole.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The cross-contamination prevention conveying equipment for swine compound premix of the present invention example separately and sealedly conveys different types and batches of premixes to reduce the influence caused between various premixes, ensure the quality of the compound premix, control the working of the air supply assembly to convey air flow into the air supply duct, and the air flow in the air supply duct enters the conveying pipeline through the connecting pipe. The air flow assists the premix to move in the conveying pipeline and avoids the accumulation and blockage of the premix in the conveying pipeline.

[0017] 2. For the cross-contamination prevention conveying equipment for swine compound premix of the present invention example, when producing bio-fermented premix and the internal water content is on the high side resulting in high humidity, the electric heating plate can be controlled to work. Under the heat conduction of the heat preservation liquid, the temperature control box heats the connecting pipe. When the air flow enters the conveying pipeline through the connecting pipe, it is heated and can be used for drying the premix, which is convenient for the preparation of the compound premix. When the water content of the premix is on the low side resulting in excessive dust, the water pump group is controlled to pump water from the outside, and the water pumped by the water pump group enters the water spraying box through the water inlet pipe and is sprayed out through the atomizing nozzles on the water spraying box. Then, the water mist is driven by the air flow conveyed by the air supply assembly into the conveying pipeline and mixed with the premix, which is convenient for humidifying the premix.

[0018] 3. For the cross - contamination prevention conveying equipment of the compound premix for pigs in the examples of the present invention, the telescopic cylinder is controlled to work to push the arc - shaped restraint plate to move, so that the arc - shaped restraint plate squeezes the feeding hose to deform and contract inward. Then, the driving assembly drives the annular moving plate to move to adjust the extrusion position of the arc - shaped restraint plate on the feeding hose, facilitating the pushing of the premix in the feeding hose to move and realizing the horizontal conveying of the premix. In addition, after the feeding hose is squeezed and contracted by the arc - shaped restraint plate, its diameter decreases. When the air flow passes through this position, it can be used for the condensation of the air flow, thereby increasing the air flow velocity. If the premix accumulates in the feeding hose, it can be dredged in this way.

[0019] 4. For the cross - contamination prevention conveying equipment of the compound premix for pigs in the examples of the present invention, when the driving motor drives the driving screw to rotate forward to make the feeding component feed, the driving screw drives the deformation of the spring in the spring box through the one - way transmission mechanism, applying a force to the spring to make it rotate and contract. When the driving motor drives the driving screw to rotate reversely to make the feeding component reset, the one - way transmission mechanism disconnects the connection between the driving screw and the spring box, facilitating the use of the spring box. After the spring in the spring box is stressed and contracted, the spring restores its deformation under the action of its own elasticity. During this process, the spring in the spring box drives the output shaft to rotate, and the output shaft drives the toothed disk to rotate through the gear. When the premix passes through the crushing hole, the rotating toothed disk and the stationary crushing disk apply forces to the premix to crush it. The setting of the spring box enables the gear to rotate continuously for a long time, ensuring that the toothed disk and the crushing disk continuously crush the premix. Since the feeding component also operates continuously, the driving screw can indirectly apply force to the spring box, further extending the rotation duration of the spring box driving the gear and facilitating the use of this conveying equipment.

[0020] 5. For the cross - contamination prevention conveying equipment of the compound premix for pigs in the examples of the present invention, after the conveying pipeline finishes conveying the premix, the switch valve on the connecting pipe is opened, and the water pump group and the air - supply component are controlled to work. When the air - supply component conveys air flow to the conveying pipeline, it carries water mist, facilitating the cleaning of the inside of the conveying pipeline. During the cleaning process, the sampling box collects the cleaning water, and the cleaning quality inside the conveying pipeline can be judged according to the cleanliness of the water collected in the sampling box. When the cleaning is completed, the water pump group is turned off and the electric heating plate is controlled to work, so that the air - supply component conveys hot air into the conveying pipeline, facilitating the drying treatment of the conveying pipeline and avoiding the growth of bacteria due to water droplets adhering to the inside of the conveying pipeline for a long time.

DETAILED DESCRIPTION

[0032] 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 - 10, the present invention provides a technical solution: a cross - contamination prevention conveying device for pig compound premix, including a conveying pipeline 1 and a blowing pipeline 5. The conveying pipeline 1 is used for conveying the premix, and the blowing pipeline 5 is used to assist the conveying pipeline 1 in conveying the premix. There are several conveying pipelines 1, and these several conveying pipelines 1 are used for conveying different types and batches of premixes, such as premixes rich in vitamins, premixes rich in minerals, premixes rich in amino acids, etc. By conveying various premixes, it is convenient for the production and preparation of compound premixes, improving the growth performance of piglets, enhancing immunity and optimizing the feed. In this solution, by separately and hermetically conveying different types and batches of premixes, the influence caused between various premixes is reduced, ensuring the quality of the compound premix. Preferably, the conveying pipeline 1 is made of food - grade stainless steel material.

[0034] At the top of the conveying pipeline 1, there is a feeding assembly, and the feeding assembly includes a storage tank 2 and a feeding tank 3. The feeding tank 3 is installed at the lower part of the side of the storage tank 2 and is communicated with the inner cavity of the storage tank 2, and the feeding tank 3 is fixed at the top end of the conveying pipeline 1 and is communicated with the inner cavity of the conveying pipeline 1. An inlet is opened in the upper part of the side of the storage tank 2, and a sealing plate 4 is movably arranged in the inlet. The storage tank 2 provides a space for storing the premix. By opening the inlet with the sealing plate 4, the premix can be replenished into the storage tank 2. When the premix is fed, the premix in the storage tank 2 enters the conveying pipeline 1 through the feeding tank 3, and the conveying pipeline 1 conveys the premix.

[0035] An installation shaft 31 is rotatably installed in the feeding tank 3. Several limiting blades 32 are fixed on the side of the installation shaft 31. A servo - motor 33 is installed outside the feeding tank 3, and the output shaft of the servo - motor 33 is fixedly connected to one end of the installation shaft 31. The limiting blades 32 installed on the side of the installation shaft 31 are used to limit the premix in the feeding tank 3. By controlling the operation of the servo - motor 33, the servo - motor 33 drives the installation shaft 31 to rotate, driving the limiting blades 32 to move in the feeding tank 3, realizing the feeding of the premix. The setting of the limiting blades 32 is convenient for controlling the feeding amount of the premix and facilitating the ratio of the compound premix.

[0036] One end of the air supply duct 5 is provided with an air supply component 6, and the air outlet of the air supply component 6 is communicated with the inner cavity of the air supply duct 5. A connecting pipe 51 communicated with its inner cavity is installed on the side of the air supply duct 5. The side of the connecting pipe 51 far away from the air supply duct 5 is fixed on the side of the conveying pipe 1 and communicated with the inner cavity of the conveying pipe 1. The air supply component 6 includes, but is not limited to, an air pump or a blower. Control the air supply component 6 to work to convey air flow into the air supply duct 5. The air flow in the air supply duct 5 enters the conveying pipe 1 through the connecting pipe 51. The air flow assists the premix to move in the conveying pipe 1, avoiding the accumulation and blockage of the premix in the conveying pipe 1. A protective filter screen 7 is installed at the air inlet of the air supply component 6. The protective filter screen 7 is used for filtering foreign matters outside, avoiding foreign matters outside from entering the air supply component 6 and affecting or even damaging the use of the air supply component 6. At the same time, filtering foreign matters such as dust and hair outside through the protective filter screen 7 ensures the quality of the premix in the conveying pipe 1.

[0037] A heating component is arranged on the side of the connecting pipe 51. The heating component includes a temperature control box 53 installed outside the connecting pipe 51. The temperature control box 53 is filled with a heat preservation liquid. The heat preservation liquid includes, but is not limited to, oil liquid or water. An electric heating plate 54 is installed on the side of the temperature control box 53, and the heating end of the electric heating plate 54 is located in the heat preservation liquid. When the humidity inside the premix is relatively high, the electric heating plate 54 can be controlled to work. Under the action of the heat conduction of the heat preservation liquid, the temperature control box 53 heats the connecting pipe 51. When the air flow enters the conveying pipe 1 through the connecting pipe 51, it is heated and can be used for drying the premix, facilitating the preparation of the composite premix.

[0038] A switching valve 52 is installed on the connecting pipe 51. The switching valve 52 is located between the temperature control box 53 and the air supply duct 5. The switching valve 52 is used to control the air flow in the connecting pipe 51, facilitating the conveyance of air flow with different degrees into different conveying pipes 1 according to requirements. When the air supply component 6 is used in cooperation with the heating component, it can be used for heating and drying the premix in different conveying pipes 1 to different degrees.

[0039] A water spraying component is arranged on the side of the air supply duct 5. The water spraying component includes a water pump group 82 and a water spraying tank 8. An installation opening is formed in the upper part of the side of the air supply duct 5. The water spraying tank 8 is clamped in the installation opening. A plurality of atomizing nozzles are installed on the side of the water spraying tank 8, and the atomizing nozzles are located inside the air supply duct 5. A water inlet pipe 81 communicated with the inner cavity of the water spraying tank 8 is arranged at the water outlet end of the water pump group 82. The water spraying tank 8 is movably clamped with the air supply duct 5 through the installation opening, facilitating the removal of the water spraying tank 8 from the air supply duct 5 to clean and replace the atomizing nozzles. When the humidity of the premix does not meet the standard, control the water pump group 82 to work to pump water from the outside. The water flow pumped by the water pump group 82 enters the water spraying tank 8 through the water inlet pipe 81 and is sprayed out through the atomizing nozzles on the water spraying tank 8. Then, the water mist is driven by the air flow conveyed by the air supply component 6 to enter the conveying pipe 1 and mix with the premix, facilitating the humidification treatment of the premix.

[0040] At the bottom of the conveying pipeline 1, there is a discharge pipe 16. The discharge pipe 16 is fixedly connected to the conveying pipeline 1 through a positioning rod 18. And a feeding hose 17 is fixedly installed between the discharge pipe 16 and the conveying pipeline 1. The material of the feeding hose 17 includes but is not limited to rubber or plastic. A pushing assembly is arranged between the conveying pipeline 1 and the discharge pipe 16 for assisting the premix to move in the feeding hose 17. The feeding hose 17 is arranged in the horizontal direction of the feeding path or can also be arranged on a gentle uphill slope. By setting the pushing assembly to squeeze the feeding hose 17 to deform, the premix is conveyed. As Figure 1 , Figure 2 shown, the setting of the pushing assembly facilitates the conveying of the premix.

[0041] The pushing assembly includes an annular moving plate 22. A number of sets of telescopic cylinders 23 are fixedly arranged on the side of the annular moving plate 22. The telescopic cylinders 23 include but are not limited to servo electric cylinders or electric hydraulic cylinders. And the telescopic ends of the telescopic cylinders 23 face the center of the annular moving plate 22. An arc-shaped restraint plate 24 is fixed at the telescopic ends of the telescopic cylinders 23. A driving assembly for driving the annular moving plate 22 to move is arranged on the upper part of the side of the discharge pipe 16. Control the telescopic cylinders 23 to work to push the arc-shaped restraint plate 24 to move, so that the arc-shaped restraint plate 24 squeezes the feeding hose 17 to deform and shrink inward. Then, drive the annular moving plate 22 to move through the driving assembly to adjust the squeezing position of the arc-shaped restraint plate 24 on the feeding hose 17, which is convenient for pushing the premix in the feeding hose 17 to move, realizing the conveying of the premix in the horizontal direction; In addition, after the feeding hose 17 is squeezed and shrunk by the arc-shaped restraint plate 24, its diameter decreases. When the air flow passes through, it can be used for the condensation of the air flow, thereby increasing the air flow velocity. If the premix accumulates in the feeding hose 17, it can be dredged in this way.

[0042] When the pushing assembly moves from the conveying pipeline 1 to the discharge pipe 16, control the telescopic cylinders 23 to work to make the arc-shaped restraint plate 24 squeeze the feeding hose 17 to deform and shrink inward. Then, during the process of driving the pushing assembly to move by the driving assembly, assist the conveying of the premix; When the pushing assembly moves from the discharge pipe 16 to the conveying pipeline 1, control the telescopic cylinders 23 to work to drive the arc-shaped restraint plate 24 to move back to its original position. At this time, the arc-shaped restraint plate 24 no longer squeezes the feeding hose 17. After the pushing assembly moves to the conveying pipeline 1, the above cycle can be repeated for auxiliary feeding.

[0043] The driving assembly includes a driving motor 19 installed on the upper part of the side of the discharge pipe 16. A driving screw 20 is installed on the output shaft of the driving motor 19. A transmission mechanism is fixed at a position on the side of the conveying pipe 1 corresponding to the driving screw 20, and one end of the driving screw 20 away from the driving motor 19 is connected to the transmission mechanism. A threaded cylinder 25 is fixed on the side of the annular moving plate 22, and the threaded cylinder 25 is in threaded connection with the driving screw 20. When the driving assembly is in use, the driving motor 19 is controlled to work to drive the driving screw 20 to rotate. The driving screw 20 drives the annular moving plate 22 to move through the threaded cylinder 25, facilitating the use of the pushing assembly.

[0044] The transmission mechanism includes a spring box 10 installed on the side of the conveying pipe 1, and a coiled spring is arranged in the spring box 10. The spring box 10 adopts the prior art and is commonly found in items such as mechanical watches and music boxes. The end of the driving screw 20 drives the spring in the spring box 10 to deform through a one-way transmission mechanism 28. The one-way transmission mechanism 28 is preferably a ratchet and pawl structure, which is commonly found in bicycles. When rotating forward, the pawl drives the ratchet to rotate, and when rotating backward, the pawl disconnects from the ratchet and the ratchet idles. In this conveying equipment, when the driving motor 19 drives the driving screw 20 to rotate forward to convey materials by the pushing assembly, the driving screw 20 drives the spring in the spring box 10 to deform through the one-way transmission mechanism 28, applying a force to the spring to make it rotate and contract. When the driving motor 19 drives the driving screw 20 to rotate backward to reset the pushing assembly, the one-way transmission mechanism 28 disconnects the connection between the driving screw 20 and the spring box 10, facilitating the use of the spring box 10.

[0045] An output shaft connected to the spring is arranged on one side of the spring box 10 away from the driving screw 20, and a gear 11 is installed on the output shaft. An installation opening is formed at a position on the side of the conveying pipe 1 close to the gear 11, and a toothed disk 12 is rotatably installed in the installation opening. The toothed disk 12 meshes with the gear 11. After the spring in the spring box 10 is stressed and contracts, the spring restores its deformation due to its own elasticity. During this process, the spring in the spring box 10 drives the output shaft to rotate, and the output shaft drives the toothed disk 12 to rotate through the gear 11. A crushing disk 14 is fixed at a position on the inner side of the conveying pipe 1 close to the toothed disk 12, and a number of crushing holes are evenly formed on the side of the crushing disk 14 and the side of the toothed disk 12. When the premix passes through the crushing holes, the rotating toothed disk 12 and the stationary crushing disk 14 apply forces to the premix to crush it. The setting of the spring box 10 enables the gear 11 to rotate continuously for a long time, ensuring that the toothed disk 12 and the crushing disk 14 continuously crush the premix. Since the pushing assembly also operates continuously, the driving screw 20 can indirectly apply force to the spring box 10, further extending the rotation duration of the spring box 10 driving the gear 11, facilitating the use of this conveying equipment. A connecting rod 13 is fixed at a position on the side of the conveying pipe 1 close to the installation opening, and the connecting rod 13 is used for connecting and fixing the conveying pipe 1 at the installation opening.

[0046] A connecting shaft 15 which is fixedly connected to the crushing disc 14 is fixed at the center of the gear disc 12, and one end of the connecting shaft 15 penetrates and extends into the discharge pipe 16. A positioning frame 26 for positioning the end of the connecting shaft 15 is fixed in the discharge pipe 16. The setting of the positioning frame 26 ensures the stability of the connecting shaft 15 during rotation. A plurality of force-applying rods 27 are fixed on the side surface of the connecting shaft 15, and the force-applying rods 27 are located in the discharge pipe 16. During the rotation of the gear disc 12, the connecting shaft 15 is driven to rotate. The force-applying rods 27 installed on the connecting shaft 15 perform a dispersing operation on the premix to be discharged, avoiding the premix from sticking together when the pushing assembly extrudes the conveying hose 17 for feeding, and facilitating the mixing preparation of the composite premix.

[0047] A sampling assembly is arranged at a position on the side of the conveying pipeline 1 close to the conveying hose 17. The sampling assembly includes a mounting seat 9 installed on the side of the conveying pipeline 1. A detachable sampling box 92 is arranged at the bottom of the mounting seat 9. The top of the sampling box 92 is open. A sampling port is opened on the side surface of the conveying pipeline 1 corresponding to the sampling box 92. A clamping hole located in the upper part of the side surface of the sampling box 92 is opened on the side surface of the mounting seat 9. A baffle plate 91 for blocking and sealing the sampling port is slidably arranged in the clamping hole. When the conveying pipeline 1 conveys the premix, the staff can sample and inspect the premix in the conveying pipeline 1 through the sampling assembly to detect whether the temperature and humidity of the premix meet the standards. If the temperature and humidity of the premix do not meet the standards, the air supply assembly 6 can be used in cooperation with the heating assembly or the water spraying assembly to adjust the temperature and humidity of the premix, facilitating the preparation of the composite premix; when the sampling assembly is used, the staff pulls out the baffle plate 91 in the clamping hole to open the sampling port, and part of the premix is discharged through the sampling port and collected by the sampling box 92 during the conveyance of the premix by the conveying pipeline 1, facilitating the detection of the temperature and humidity of the premix.

[0048] After the conveying pipeline 1 finishes conveying the premix, the switch valve 52 on the communicating pipe 51 is opened, and the water pump group 82 and the air supply assembly 6 are controlled to work. When the air supply assembly 6 conveys air to the conveying pipeline 1, it carries water mist, facilitating the cleaning of the inside of the conveying pipeline 1. During the cleaning process, the sampling box 92 collects the cleaning water, and the cleaning quality of the inside of the conveying pipeline 1 can be judged according to the cleanliness of the water collected in the sampling box 92. After the cleaning is completed, the water pump group 82 is turned off and the electric heating plate 54 is controlled to work, so that the air supply assembly 6 conveys hot air into the conveying pipeline 1, facilitating the drying treatment of the conveying pipeline 1 and avoiding bacteria breeding due to long-term attachment of water droplets in the conveying pipeline 1.

[0049] The servo motor 33, electric heating plate 54, water pump group 82, fan group 11, battery pack 12, drive motor 19, telescopic cylinder 23, etc. used in the present invention are all common electronic components in the prior art, and their working modes and circuit structures are all well-known technologies.
