Description

Technical Field

[0001] This invention relates to the field of piglet milk preparation and feeding technology, specifically to a piglet milk preparation device and a feeding device. Background Technology

[0002] After a sow gives birth to piglets, the newborn piglets are relatively weak. If the piglets cannot consume adequate milk in a timely manner to supplement their nutrition, their growth performance will be severely impaired. In modern large-scale pig farming, sows often face the problem of insufficient milk. To solve this problem, artificial milk is usually prepared and then fed to the piglets.

[0003] The quality of existing artificially prepared milk is greatly affected by the operator's operation and uncontrollable human factors, which is not conducive to the preparation of high-quality milk. At the same time, the inside of the milk discharge pipe of the existing artificially prepared milk is not easy to clean, and residual materials are easy to accumulate. The residual materials inside the milk discharge pipe will contaminate the milk consumed by piglets later, which is detrimental to the health of piglets. Summary of the Invention

[0004] The purpose of this invention is to provide a piglet milk preparation device and a feeding device. Using this invention, the piglet milk preparation device and feeding device can achieve automated and precise control for manual milk preparation.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] As attached Figure 1-25 As shown, a piglet milk preparation device includes a milk powder supply component, a water supply component, a tank 1, a motor 15, an electric lifting device 16, a rotating shaft 17, a stirring paddle 18, a sealing plate 19, a pin 20, a cylinder 21, a block 22, a cover 23, a pin groove 26, a discharge pipe 13, a first magnet strip 14, a sealing plug 27, a reciprocating screw 28, a nut 29, a second magnet strip 30, a first scraper 31, a second scraper 32, a bracket 33, a bushing 34, a fixing frame 35, and a controller 36.

[0049] A milk powder supply assembly supplies milk powder to tank 1. The milk powder supply assembly is positioned above tank 1, with its outlet connected to the tank 1. Milk powder discharged from the outlet enters tank 1. A water supply assembly supplies drinking water to tank 1. The water supply assembly is also positioned above tank 1, with its outlet connected to the tank 1. Drinking water discharged from the outlet enters tank 1. The motor 15 is connected to the electric lifting device 16. A motor 15 is positioned above a tank body 1, with an electric lifting device 16 above the tank body 1 and a motor 15 above the electric lifting device 16. The motor 15 is positioned above the tank body 1 via the electric lifting device 16. The tank body 1 may be made of plastic. A rotating shaft 17, a stirring paddle 18, a sealing plate 19, a pin 20, a cylinder 21, a block 22, and a cover 23 are disposed inside the tank body 1. The rotating shaft 17 is vertically positioned, and the stirring paddle 18 is mounted on the rotating shaft 17. The cylinder 21 is a hollow sleeve, and the height of the cylinder 21 is greater than the height of the block 22. The block 22 is disposed inside the cylinder 21. At the end, a second circular hole 25 and a pin groove 26 are provided in the middle of the block 22. The pin groove 26 is an elongated through hole. The pin groove 26 and the second circular hole 25 on the block 22 meet in the middle of the block 22. The cover 23 is provided on the upper outer side of the cylinder 21. The cover 23 is a cap-shaped cover with its opening facing downwards. A first circular hole 24 is provided in the middle of the cover 23. The cover 23 covers the upper end of the cylinder 21. It can be connected into a whole by inserting a fastener 43 into the fixing holes of the cylinder 21, the block 22, and the cover 23; or, the fastener 43 can also be inserted into the cylinder 21. In the fixing hole of block 22, cylinder 21 and block 22 are connected as one unit. Then, another fixing member 43 is inserted into the fixing hole of cylinder 21 and cover 23 to connect cylinder 21 and cover 23 as one unit. The fixing member 43 is a screw or pin. The number of fixing members 43 can be no less than two, and the number of fixing members 43 can be set as many as needed. When there are multiple fixing members 43, the multiple fixing members 43 are arranged symmetrically. According to the use needs, cylinder 21, block 22 and cover 23 can be disassembled by removing the fixing members 43, which is convenient to use.

[0050] The lower end of the rotating shaft 17 passes through the first circular hole 24 on the cover 23 and the second circular hole 25 on the block 22. A pin 20, a long, round rod, is provided at the lower end of the rotating shaft 17. The pin 20 is inserted and fixed to the lower end of the rotating shaft 17. The pin 20 is movably embedded in the pin groove 26 on the block 22, and the pin groove 26 matches the pin 20. When the rotating shaft 17 moves downwards, the pin 20 can move downwards out of the pin groove 26 on the block 22 and then enter the cavity of the cylinder 21 below the block 22. The height of the cavity of the cylinder 21 below the block 22 can be sufficiently large. The height of the cavity of the cylinder 21 below the block 22 is greater than the diameter of the pin 20. After the pin 20 enters the cavity of the cylinder 21 below the block 22, the pin 20 can rotate together with the rotating shaft 17. The pin 20 can rotate in the cavity of the cylinder 21 below the block 22. When the rotating shaft 17 moves upward, the pin 20 enters the area of ​​the pin groove 26. The pin 20 can smoothly move upward into the pin groove 26 on the block 22. When the pin 20 moves into the pin groove 26 on the block 22, the rotating shaft 17 can drive the block 22 to rotate through the pin 20.

[0051] The lower end of the cylinder 21 is connected to the upper surface of the sealing plate 19; a discharge pipe 13 is provided at the lower part of the tank 1, and the upper port of the discharge pipe 13 is connected to the discharge port at the lower part of the tank 1. The discharge pipe 13 is vertically arranged and is made of plastic and magnetically permeable material. The magnetic field of the magnet can pass through the pipe wall of the discharge pipe 13 to generate a magnetic force. The sealing plug 27 is inserted into the upper port of the discharge pipe 13, and the upper surface of the sealing plug 27 is connected to the lower surface of the sealing plate 19. For example, the upper surface of the sealing plug 27 and the lower surface of the sealing plate 19 can be made of adhesive. Water-sealed adhesive connections, etc., can also assist in mechanical fastening connections. Two first magnet strips 14 are symmetrically fixed on the outer diameter of the discharge pipe 13. The two first magnet strips 14 can be fixed on the outer side of the discharge pipe 13 by clamps, pipe clamps, or other fixing devices. The length direction of the two first magnet strips 14 is parallel to the radial direction (axis) of the discharge pipe 13. The first magnet strips 14 are strong magnets. The reciprocating screw 28 is vertically set in the middle of the discharge pipe 13. The middle of the sealing plug 27 is provided with a first through hole 40. The upper end of the reciprocating screw 28 passes through the sealing plug 27. The first through hole 40 on the plug 27 connects the upper end of the reciprocating screw 28 to the middle of the lower surface of the sealing plate 19. The reciprocating screw 28 is coaxial with the rotating shaft 17, meaning the vertical axis of the reciprocating screw 28 and the vertical axis of the rotating shaft 17 are on the same axis. The reciprocating screw 28 is also coaxial with the discharge pipe 13, meaning the vertical axis of the reciprocating screw 28 and the vertical axis of the discharge pipe 13 are on the same axis. A nut 29 is provided, and two second magnet strips 30 are symmetrically arranged on the outer diameter of the nut 29. The length direction of the two second magnet strips 30 is parallel to the radial direction (axis) of the discharge tube 13, and the length direction of the two second magnet strips 30 is parallel to the radial direction (axis) of the reciprocating screw 28. The second magnet strips 30 are strong magnets. On the same side of the reciprocating screw 28, the magnetic pole of the first magnet strip 14 that contacts the outer surface of the discharge tube 13 is different from the magnetic pole of the second magnet strip 30 that is close to (or faces) the inner surface of the discharge tube 13. A specific example is as follows:

[0052] For example, in scenario one: the first magnet strip 14 and the second magnet strip 30 are located on the same cross-sectional plane, on the left side of the reciprocating screw 28. The magnetic pole of the first magnet strip 14 contacting the outer surface of the discharge tube 13 is N-level. At the same time, on the left side of the reciprocating screw 28, the magnetic pole of the second magnet strip 30 near (or towards) the inner surface of the discharge tube 13 is S-level. That is, on the left side of the reciprocating screw 28, the magnetic pole of the first magnet strip 14 contacting the outer surface of the discharge tube 13 is close to (or towards) the discharge tube 13. The magnetic poles on the inner surface of tube 13 are opposite and attract each other; on the right side of the reciprocating screw 28, the magnetic pole of the first magnet strip 14 that contacts the outer surface of the discharge tube 13 is N-position, and at the same time, on the right side of the reciprocating screw 28, the magnetic pole of the second magnet strip 30 that is close to (or faces) the inner surface of the discharge tube 13 is S-position. That is, on the right side of the reciprocating screw 28, the magnetic pole of the first magnet strip 14 that contacts the outer surface of the discharge tube 13 and the magnetic pole of the second magnet strip 30 that is close to (or faces) the inner surface of the discharge tube 13 are opposite and attract each other.

[0053] For example, in scenario two: the first magnet strip 14 and the second magnet strip 30 are located on the same cross-sectional plane, on the left side of the reciprocating screw 28. The magnetic pole of the first magnet strip 14 contacting the outer surface of the discharge tube 13 is S-pole. At the same time, on the left side of the reciprocating screw 28, the magnetic pole of the second magnet strip 30 near (or towards) the inner surface of the discharge tube 13 is N-pole. That is, on the left side of the reciprocating screw 28, the magnetic pole of the first magnet strip 14 contacting the outer surface of the discharge tube 13 is close to (or towards) the discharge tube 13. The magnetic poles on the inner surface of tube 13 are opposite and attract each other; on the right side of the reciprocating screw 28, the magnetic pole of the first magnet strip 14 that contacts the outer surface of the discharge tube 13 is S-pole, and at the same time, on the right side of the reciprocating screw 28, the magnetic pole of the second magnet strip 30 that is close to (or faces) the inner surface of the discharge tube 13 is N-pole. That is, on the right side of the reciprocating screw 28, the magnetic pole of the first magnet strip 14 that contacts the outer surface of the discharge tube 13 and the magnetic pole of the second magnet strip 30 that is close to (or faces) the inner surface of the discharge tube 13 are opposite and attract each other.

[0054] For example, in scenario three: the first magnet strip 14 and the second magnet strip 30 are located on the same cross-sectional plane, on the left side of the reciprocating screw 28. The magnetic pole of the first magnet strip 14 contacting the outer surface of the discharge tube 13 is N-level. At the same time, on the left side of the reciprocating screw 28, the magnetic pole of the second magnet strip 30 near (or towards) the inner surface of the discharge tube 13 is S-level. That is, on the left side of the reciprocating screw 28, the magnetic pole of the first magnet strip 14 contacting the outer surface of the discharge tube 13 is close to (or towards) the discharge tube 13. The magnetic poles on the inner surface of tube 13 are opposite and attract each other; on the right side of the reciprocating screw 28, the magnetic pole of the first magnet strip 14 that contacts the outer surface of the discharge tube 13 is S-pole, and at the same time, on the right side of the reciprocating screw 28, the magnetic pole of the second magnet strip 30 that is close to (or faces) the inner surface of the discharge tube 13 is N-pole. That is, on the right side of the reciprocating screw 28, the magnetic pole of the first magnet strip 14 that contacts the outer surface of the discharge tube 13 and the magnetic pole of the second magnet strip 30 that is close to (or faces) the inner surface of the discharge tube 13 are opposite and attract each other.

[0055] For example, in scenario four: the first magnet strip 14 and the second magnet strip 30 are located on the same cross-sectional plane, on the left side of the reciprocating screw 28. The magnetic pole of the first magnet strip 14 contacting the outer surface of the discharge tube 13 is S-pole. At the same time, on the left side of the reciprocating screw 28, the magnetic pole of the second magnet strip 30 near (or towards) the inner surface of the discharge tube 13 is N-pole. That is, on the left side of the reciprocating screw 28, the magnetic pole of the first magnet strip 14 contacting the outer surface of the discharge tube 13 is close to (or towards) the discharge tube 13. The magnetic poles on the inner surface of tube 13 are opposite and attract each other; on the right side of the reciprocating screw 28, the magnetic pole of the first magnet strip 14 that contacts the outer surface of the discharge tube 13 is N-position, and at the same time, on the right side of the reciprocating screw 28, the magnetic pole of the second magnet strip 30 that is close to (or faces) the inner surface of the discharge tube 13 is S-position. That is, on the right side of the reciprocating screw 28, the magnetic pole of the first magnet strip 14 that contacts the outer surface of the discharge tube 13 and the magnetic pole of the second magnet strip 30 that is close to (or faces) the inner surface of the discharge tube 13 are opposite and attract each other.

[0056] In this invention, the length, width, thickness, magnetic field strength, and other specifications of the first magnet strip 14 and the second magnet strip 30 can be flexibly set as needed. This ensures that, under the action of two pairs of mutually attracting first magnet strips 14 and second magnet strips 30 on the left and right sides of the reciprocating screw 28, the direction of the nut 29 remains unchanged, i.e., the nut 29 is kept from rotating. Furthermore, two or more pairs of first magnet strips 14 and second magnet strips 30 can be provided, with multiple pairs of mutually attracting first magnet strips 14 and second magnet strips 30 arranged symmetrically.

[0076] A feeding trough 38 for feeding piglets is placed below the lower port of the discharge pipe 13. The milk prepared by the piglet milk preparation device of the present invention is discharged from the lower port of the discharge pipe 13 into the feeding trough 38, and the piglets can eat the prepared milk in the feeding trough 38.

[0077] The present invention also aims to provide a piglet feeding device, which includes the piglet milk preparation device as described above, and further includes a housing 37 and a feeding trough 38. The piglet milk preparation device is disposed inside the housing 37, that is, the housing 37 is disposed outside the piglet milk preparation device. The feeding trough 38 is disposed in the lower part of the housing 37 and is detachably installed. The lower port of the discharge pipe 13 is located above the feeding trough 38. The prepared milk is discharged from the lower port of the discharge pipe 13 into the feeding trough 38 for storage. Piglets can consume the prepared milk in the feeding trough 38. The structure and style of the housing 37 can be flexibly customized as needed. The design allows piglets to easily access milk from the feeding trough 38. Preferably, the front and / or rear sides of the lower part of the shell 37 are open, meaning that the front and / or rear sides of the lower part of the shell 37 have openings, or the front side of the lower part of the shell 37 has an opening, or the rear side of the lower part of the shell 37 has an opening, or both the front and rear sides of the lower part of the shell 37 have openings. Piglets can access the milk in the feeding trough 38 through the openings on the front and / or rear sides of the lower part of the shell 37. Depending on the need for flexible use, the shell 37 can be further secured, for example, by fixing the lower part of the shell 37 to the ground in the piglet feeding area using expansion screws.

[0078] Preferably, the housing 37 also includes a movable door 39. Movable doors 39 are provided on both sides of the upper part of the housing 37. Preferably, a movable door 39 is provided on the top of the housing 37. During operation, the components inside the housing 37 can be operated or maintained by opening the movable door 39.

[0079] When using the piglet milk preparation device described in this invention, milk powder can be added to container 3 for storage.

[0080] Add drinking water to the water tank 4 in the water supply assembly, or connect the drinking water supply pipe to the water inlet 7 at the top of the water tank 4. The drinking water is added to the water tank 4 in the water supply assembly from the water inlet 7 at the top of the water tank 4. When the water level in the water tank 4 reaches the required water level, the float valve 8 floats up and automatically closes to add water to the water tank 4.

[0081] When using the piglet feeding device described in this invention, the movable doors 39 on both sides of the upper part of the housing 37 or the movable door 39 on the top of the housing 37 can be opened as needed to add milk powder into the container 3 for storage.

[0082] The power supply of each electrical device in this invention is turned on, and the required water temperature in the water tank 4 is set by the controller 36. The electric heating device 5 is started by the controller 36 to start heating. The electric heating device 5 heats the water in the water tank 4. The temperature probe 6 monitors the temperature of the water in the water tank 4 in real time and transmits the monitoring signal to the controller 36 in real time. When the real-time temperature of the water in the water tank 4 reaches the temperature value set by the controller 36, the controller 36 controls the electric heating device 5 to stop heating. When the real-time temperature of the water in the water tank 4 is lower than the set temperature value, the controller 36 starts the electric heating device 5 again to start heating. The above automatic cycle realizes the automatic maintenance of the temperature of the water in the water tank 4, and maintains the water temperature in the water tank 4 at the required temperature.

[0083] During the process of heating water in the water tank 4 by the electric heating device 5, the electric stirrer 9 can also be started by the controller 36 to rotate and stir the water in the water tank 4.

[0084] The controller 36 adjusts the electric lifting device 16 to descend, causing the motor 15 to descend to its lowest position. The rotating shaft 17 descends synchronously with the motor 15 to its lowest position. The lower end of the rotating shaft 17 pushes down the sealing plate 19 and the sealing plug 27, causing the sealing plug 27 to be stably inserted into the upper port of the discharge pipe 13. The edge of the sealing plug 27 contacts the upper port of the discharge pipe 13, achieving a seal on the upper port of the discharge pipe 13, thus sealing the discharge port at the bottom of the tank 1. Material stored in the tank 1 will not enter the discharge pipe 13. In this state, the pin 20 moves downward out of the pin groove 26 on the block 22 and enters the cavity of the cylinder 21 below the block 22.

[0085] The controller 36 sets the required amount of water to be added to tank 1 for a batch. The controller 36 then opens the solenoid valve 11, and the water stored in tank 4 flows down through the pipe, through the metering device 10 and the solenoid valve 11, and into tank 1. The metering device 10 monitors the amount of water flowing into tank 1 in real time and transmits the monitoring signal to the controller 36 in real time. When the amount of water flowing into tank 1 reaches the required amount of water to be added to tank 1 for a batch set by the controller 36, the controller 36 automatically closes the solenoid valve 11 and stops adding water to tank 1.

[0086] When water needs to be added to tank 1 quickly, the water pump 12 can be turned on by the controller 36 during the process of adding water to tank 1 by opening the solenoid valve 11. The water pump 12 will quickly add water to tank 1. When the amount of water flowing into tank 1 reaches the amount of water to be added to tank 1 set by the controller 36 for the batch, the controller 36 will automatically turn off the water pump 12 and the solenoid valve 11 at the same time. Alternatively, the water pump 12 can be turned off in advance before the amount of water flowing into tank 1 reaches the amount of water to be added to tank 1 set by the controller 36 for the batch. When the amount of water flowing into tank 1 reaches the amount of water to be added to tank 1 set by the controller 36 for the batch, the controller 36 will automatically turn off the solenoid valve 11 and stop adding water to tank 1.

[0087] Before adding milk powder to tank 1, the feeding amount of the feeding device 2 per unit time can be checked and measured to determine the rotation speed and running time of the feeding device 2 when adding the required mass of milk powder to tank 1 in batches. Then, the rotation speed and running time of the feeding device 2 can be set through the controller 36. That is, the batch quantitative milk powder addition setting of the feeding device 2 is completed through the controller 36. The feeding device 2 is started by the controller 36, and the feeding device 2 begins to add milk powder into tank 1. When the running time of the feeding device 2 reaches the set value, the controller 36 automatically controls the feeding device 2 to stop adding milk powder into tank 1.

[0088] The controller 36 sets the appropriate speed of the motor 15, and starts the motor 15. The motor 15 drives the stirring paddle 18 to rotate through the rotating shaft 17. The stirring paddle 18 stirs the drinking water and milk powder in the tank 1 to produce the required milk liquid, thus realizing the preparation of piglet milk liquid.

[0089] When the rotating shaft 17 and the stirring paddle 18 rotate, the pin 20 has moved downward out of the pin groove 26 on the block 22 and enters the cavity of the cylinder 21 below the block 22. The pin 20 rotates in the cavity of the cylinder 21 below the block 22. The pin 20 cannot act on the block 22 and the cylinder 21. At this time, the block 22, the cylinder 21, the cover 23, and the sealing plate 19 are all stationary and maintain their original state.

[0090] Once the required milk is produced in tank 1, the control motor 15 stops running, and the electric lifting device 16 is slowly raised by the controller 36. The motor 15 is slowly lifted by the electric lifting device 16, and the rotating shaft 17 also moves upward synchronously. The pin 20 can simultaneously drive the cylinder 21 to move upward (the pin 20 can push the lower surface of the block 22 or the lower surface of the cover 23 upward). Then, the sealing plate 19, the sealing plug 27, and the reciprocating screw 28 all move upward synchronously. The lower end of the reciprocating screw 28 moves upward in the bushing 34. The bushing 34 keeps the lower end of the reciprocating screw 28 centrally stable. The sealing plug 27 disengages from the upper port of the discharge pipe 13, the discharge port at the bottom of tank 1 is opened, and the milk in tank 1 is discharged downward from the discharge pipe 13.

[0091] The milk in tank 1 is discharged into the feeding trough 38 below through the discharge pipe 13 for storage. Piglets can consume the milk in the feeding trough 38 of the piglet feeding device described in this invention.

[0092] After the milk in tank 1 has been discharged, the process of adding water to tank 1 can be repeated as needed. The tank 1 is cleaned by adding clean water. During the cleaning process, motor 15 can be turned on and adjusted to a suitable speed. The motor 15 drives the stirring paddle 18 to rotate. The stirring paddle 18 rotates and stirs the clean water in tank 1 to rinse and clean the inside of tank 1. The rubber or silicone strips on the outer edge of the stirring paddle 18 can also scrape off the residual material attached to the inner wall of tank 1, further improving the cleaning effect.

[0093] With the sealing plug 27 disengaged from the upper port of the discharge pipe 13, the motor 15 is started. The motor 15 maintains a suitable slow speed, and the rotating shaft 17 rotates synchronously. When the pin 20 enters the opening area of ​​the pin groove 26, the pin 20 moves into the pin groove 26 on the block 22. When the pin 20 moves into the pin groove 26 on the block 22, the pin 20 pushes the lower surface of the cover 23. The rotating shaft 17 pushes the side wall of the pin groove 26 on the block 22 through the side of the pin 20, causing the block 22 to rotate. Subsequently, the cylinder 21 and the cover 23 rotate. 3. The sealing plate 19 and the reciprocating screw 28 also rotate synchronously with the block 22. At this time, since the nut 29 does not rotate, the reciprocating screw 28 rotates. The nut 29 will move up and down on the reciprocating screw 28. The thread lead on the reciprocating screw 28 can be flexibly set to the required length as needed. The nut 29 in the reciprocating motion drives the first scraper 31 and the second scraper 32 to move up and down in the discharge pipe 13, thereby cleaning the inner wall of the discharge pipe 13 through the up and down reciprocating motion of the first scraper 31 and the second scraper 32.

[0094] During the cleaning of the inner wall of the discharge pipe 13 by the first scraper 31 and the second scraper 32, the above-mentioned operation of adding water to the tank 1 can be repeated. The clean water added to the tank 1 flows downward into the discharge pipe 13. The clean water flowing into the discharge pipe 13, together with the first scraper 31 and the second scraper 32 moving up and down in the discharge pipe 13, cleans the inner wall of the discharge pipe 13 thoroughly. Because the opening diameter of the second through hole 41 on the first scraper 31 and the second scraper 32 is larger than that of the previous one, the inner wall of the discharge pipe 13 can be thoroughly cleaned. The outer diameter of the reciprocating screw 28 and the second through holes 41 on the first scraper 31 and the second scraper 32 are all appropriately spaced from the reciprocating screw 28. During the above cleaning process, the cleaning water can flow smoothly down and be discharged from the discharge pipe 13 through the gap between the second through hole 4 on the first scraper 31 and the reciprocating screw 28, and through the gap between the second through hole 4 on the second scraper 32 and the reciprocating screw 28. The cleaning water can also flow smoothly down and be discharged from the discharge pipe 13 through the third through holes 42 provided on the first scraper 31 and the second scraper 32.

[0095] As the nut 29 reciprocates up and down on the reciprocating screw 28, the first scraper 31 can rise above the upper port of the discharge pipe 13 with the help of the extension of the bracket 33. Since the diameter of the second through hole 41 on the second scraper 32 is greater than or equal to the outer diameter of the bushing 34, the bushing 34 can pass through the second through hole 41 on the second scraper 32 during the descent of the second scraper 32. With the help of the extension of the bracket 33, the second scraper 32 can descend to the lower part of the bushing 34. The second scraper 32 can also descend to the lower port of the discharge pipe 13, making the cleaning of the discharge pipe 13 more complete and comprehensive.

[0096] During the process of cleaning the inner wall of the discharge pipe 13 with the aid of the first scraper 31 and the second scraper 32, the liquid residue can flow down and be discharged from the discharge pipe 13 through the second through hole 41 and the third through hole 42 provided on the first scraper 31 and the second scraper 32.

[0097] The piglet milk preparation device and feeding device of the present invention can realize automated and precise control for manual milk preparation. The precise control of milk preparation eliminates the uncontrollable factors of human error in manual milk preparation to the greatest extent, which is conducive to the preparation of high-quality milk. The milk discharge pipe in the piglet milk preparation device and feeding device of the present invention can be thoroughly cleaned. The cleaning operation is convenient, and there is little material residue inside the milk discharge pipe after cleaning. The milk consumed by piglets is clean and hygienic, which helps to protect the health of piglets.
