Description

Technical Field

[0001] The present invention relates to the technical field of feed processing, and particularly to a feed stirring and mixing device based on an automatic feeding system. Background Art

[0002] In a farm automatic feeding system, a stirring device is required to stir and mix feed for better feeding. For example, in the prior art, the patent document with the publication number CN108479552B discloses an efficient pig feed stirring device. The technical solution it solves includes a horizontally placed tank body. There are grooves on the inner edge surface of the tank body. There are arc-shaped plates on both sides of the grooves. Baffles and stirring rods are fixed on the arc-shaped plates. The outer ends of the stirring rods are hinged with connecting rods. The ends of adjacent connecting rods are hinged to form a hinge point. The intermittent rotation of the tank body makes the hinge point located directly below in turn. There is a box body below the tank body. There is a vertical rod in the box body. The vertical rod moves up and down reciprocally and pushes the hinge point to move up and down. There is a coaxially rotatable rotating shaft in the tank body. There is a first stirring rod on the rotating shaft. There are multiple cross rods in the tank body that are in the same direction as the rotating shaft and are circumferentially distributed. There are several second stirring rods that are radial and misaligned with the first stirring rod on the cross rods. The end of the second stirring rod is connected with a crushing block. The above-mentioned efficient pig feed stirring device inputs various feeds into the tank body for centralized stirring and mixing. Usually, it is relatively large in volume and has a very limited applicable application scenario.

[0003] To sum up, the existing stirring devices are mostly designed for centralized mixing. In the actual use process, when adding water and mixing feed before feeding in a pig farm, using a stirring device for centralized mixing, if it is transported to each feeding trough through a pipeline to achieve point feeding, when the conveying pipeline is relatively long, it is difficult to control the feeding amount, and the residual feed in the pipeline is difficult to clean, which is easy to breed bacteria and affect the health of livestock. Based on this, the existing stirring devices cannot meet the use requirements of point-feed stirring and feeding in an automatic feeding system and urgently need to be solved. Summary of the Invention

[0004] The purpose of the present invention is to provide a feed stirring and mixing device based on an automatic feeding system to solve the problem in the prior art that the existing stirring devices cannot meet the use requirements of point-feed stirring and feeding in an automatic feeding system.

[0005] To achieve the above purpose, the present invention adopts the following technical scheme: A feed stirring and mixing device based on an automatic feeding system includes a hopper and a material control cylinder fixedly installed at the bottom of the hopper. A transmission shaft is rotatably installed inside the hopper. A stirring assembly is installed at the bottom end of the transmission shaft. A driving motor is fixedly installed on the surface of the hopper. The driving motor drives the transmission shaft to rotate through belt transmission. A water supply pipe is fixedly installed outside the hopper. The outlet end of the water supply pipe extends into the hopper. A liquid level gauge is arranged inside the hopper.

[0006] An activity plate is slidably installed inside the material control cylinder. An electric telescopic rod is fixedly installed at the bottom of the material control cylinder, and the telescopic end of the electric telescopic rod is fixedly connected to the bottom of the activity plate. A diversion pipe is fixedly installed on the surface of the material control cylinder.

[0007] The present invention proposes a plurality of stirring and mixing devices, which are distributed above each feeding trough. The hopper and the material control cylinder are fixedly installed above the feeding trough through brackets. The outlet end of the diversion pipe extends into the feeding trough. The automatic feeding system uses a tube chain conveyor as the feeding mechanism, and uses the tube chain conveyor to transport dry feed into the hopper for temporary storage. During use, the material transported in the tube chain conveyor is dry feed. Compared with wet feed, the dry feed remaining in the tube chain conveyor has a longer storage time and is not easy to breed bacteria. Moreover, the inner cavities of the hopper and the material control cylinder can be washed or soaked by injecting water, and the cleaning is also convenient. The stirring and mixing device proposed by the present invention can meet the use requirements of the automatic feeding system for point-by-point feed stirring and feeding.

[0008] Preferably, a partition plate is fixedly arranged inside the hopper. The partition plate divides the inner cavity of the hopper into a dry material chamber located on the upper side and a wet material chamber located on the lower side. A rotating disk is rotatably installed on the upper surface of the partition plate. A plurality of first flow holes are formed on the surface of the rotating disk, and a plurality of second flow holes are formed on the surface of the partition plate. The dry material chamber and the wet material chamber are communicated through the first flow holes and the second flow holes.

[0009] A control sleeve is fixedly installed at the center of the partition plate. The transmission shaft passes through the rotating disk and the control sleeve. A linkage assembly is arranged inside the rotating disk. The control sleeve drives the linkage assembly to act, so that the rotating disk rotates together with the transmission shaft. An electric pin is arranged inside the partition plate, and a pin hole is formed on the surface of the rotating disk. The telescopic end of the electric pin can be inserted into the pin hole to restrict the angle of the rotating disk when it stops rotating.

[0010] The linkage assembly includes a lifting ring and a magnetic ring. A guide rod is fixedly installed on the surface of the lifting ring. The guide rod is slidably inserted into the rotating disk. A support spring is sleeved on the surface of the guide rod. The two ends of the support spring are respectively fixedly connected to the rotating disk and the lifting ring. A hexagonal sleeve is fixedly installed on the surface of the transmission shaft. The magnetic ring is slidably installed on the surface of the hexagonal sleeve. A hemispherical protrusion is fixedly installed on the lower surface of the lifting ring, and a groove adapted to the hemispherical protrusion is formed on the upper surface of the magnetic ring. This design makes the feeding into the wet material chamber of the hopper controllable.

[0011] Preferably, the stirring assembly includes an orifice plate. The orifice plate is rotatably installed inside the material control cylinder, and the bottom end of the transmission shaft is fixedly connected to the orifice plate. Stirring rods are fixedly installed on the upper surface of the orifice plate. During the process of the stirring assembly stirring the material, when the stirring rods stir in layers and cooperate with the up-and-down reciprocating movement of the activity plate, it promotes the vertical flow of the feed, greatly improving the mixing efficiency.

[0012] Preferably, a magnetic sleeve is slidably sleeved on the surface of the transmission shaft. A partition plate is fixedly installed at the bottom end of the magnetic sleeve. The partition plate covers the upper surface of the orifice plate and covers the holes on the surface of the orifice plate. A cleaning sleeve is slidably sleeved on the surface of the stirring rod. The cleaning sleeve is fixedly connected to the partition plate. The top end of the cleaning sleeve is in a conical structure. Using less water, the stirring assembly can be immersed in water, which has the functions of cleaning and preventing feed residue from solidifying.

[0013] Preferably, a first excitation coil is embedded inside the top end of the control sleeve. The first excitation coil generates an electromagnetic field that repels the magnetic ring. A second excitation coil is embedded inside the bottom end of the control sleeve. The second excitation coil generates an electromagnetic field that attracts the magnetic sleeve, which can respectively control the rotation stop of the rotating disk and the up and down movement of the partition plate, achieving the effect of controlling the opening and closing of the orifice plate.

[0014] Preferably, an overflow valve is arranged on the surface of the material control cylinder. When the overflow valve is opened, the soaking water in the wet material chamber of the hopper can be drained away from the overflow valve. The liquid level gauge is fixedly installed on the lower surface of the partition plate, which is convenient for detecting the height of the material in the wet material chamber of the hopper. A plurality of material blocking arms are fixedly installed inside the hopper. The lower surface of the material blocking arm is in sliding contact with the upper surface of the rotating disk. During the rotation of the rotating disk, the material blocking arm blocks the material from rotating, facilitating the feeding of the material.

[0015] The present invention has the following beneficial effects:

[0016] 1. The stirring and mixing equipment proposed by the present invention can be installed above each feeding trough. The automatic feeding system uses a tube chain conveyor to transport dry feed to each hopper for temporary storage. The material is stirred with water through this stirring and mixing equipment, and the storage volume of the material control cylinder is adjusted by the movable disk. According to actual needs, the prepared wet feed is quantitatively put into each feeding trough. The material in each material control cylinder can be manually adjusted and controlled, and the amount of feed transported to the feeding trough is different, with the function of differential feeding. During use, the material transported in the tube chain conveyor is dry feed. Compared with wet feed, the dry feed remaining in the tube chain conveyor can be stored for a longer time and is not prone to breeding bacteria. The stirring and mixing equipment proposed by the present invention can meet the use requirements of the automatic feeding system for point-by-point feed stirring and feeding.

[0017] 2. The stirring of the feed by the stirring and mixing equipment proposed by the present invention has the following advantages:

[0018] (1) Adjust the height of the movable disk through the electric telescopic rod to change the storage volume in the material control cylinder. Taking the water injection speed of the water supply pipe into the wet material chamber of the hopper as a certain value, the dry feed in the hopper falls into the wet material chamber, and the stirring component stirs and mixes it. The liquid level of the feed rises until the liquid level gauge is triggered. At this time, the water supply pipe stops supplying water, and the first excitation coil is powered off. The telescopic end of the electric pin can be inserted into the pin hole, and the feed stops falling. The stirring component continues to stir. Then, the movable disk moves downward, so that the feed in the material control cylinder is discharged into the feeding trough through the diversion pipe. The controllable feed quantity is determined by the height of the movable disk. The stirring and mixing equipment proposed by the present invention has the function of quantitative feeding, and each stirring and mixing equipment can be independently controlled to meet the needs of differential feeding;

[0019] (2) During the process of the stirring component stirring the material, the stirring rod moves in a circular motion, promoting the layered flow of the feed. At the same time, the movable disk moves up and down reciprocally, promoting the vertical flow of the feed. The stirring and mixing equipment proposed by the present invention has the advantages of fast and uniform mixing speed of the feed, greatly improving the mixing efficiency;

[0020] (3) In the case of a large amount of feed to be fed, it takes a long time to wait for the feed to fall and the water to be injected into the wet material chamber of the hopper. This stirring and mixing equipment can first mix and process a certain amount of feed and introduce it into the feeding trough. During the process of introducing the feed into the feeding trough, water can continue to be added, the feed can continue to fall, and the feed can be stirred in the wet material chamber of the hopper. Then, control the partition disk to move up and separate from the orifice plate, and the material in the wet material chamber of the hopper can pass through the orifice plate and enter the material control cylinder. The present invention realizes the functions of batch mixing and continuous discharging, shortening the waiting time. Especially in the season with relatively low temperature, it can well ensure the temperature of the feed in the feeding trough.

[0021] 3. For the stirring and mixing equipment proposed by the present invention, the falling speed of the feed into the wet material chamber of the hopper is controlled by the rotation speed of the rotating disk. The operating speeds of the rotating disk and the stirring component are both controlled by the driving motor. When the falling amount of the feed increases, the stirring speed also increases accordingly, so that the feed falling into the water in the wet material chamber of the hopper is quickly stirred and dispersed, which can prevent the situation that the feed forms lumps due to the increase in the falling amount of the feed. Livestock need to be fed with feeds of different viscosities at different growth stages. This design adjusts the viscosity of the feed by regulating the rotation speed of the driving motor to meet the needs of differential feeding, providing conditions for the remote linkage control of the automatic feeding system.

[0022] 4. The stirring and mixing equipment proposed by the present invention performs wet material treatment above the feeding trough (the end of the automatic feeding system). That is, the dry feed is conveyed in the tube chain conveyor of the automatic feeding system, solving the problems that it is easy to leave residues and difficult to clean when wet feed is conveyed in the tube chain conveyor;

[0023] In addition, when the movable plate moves to the top of the material control cylinder, only a small amount of water needs to be injected into the wet material chamber of the hopper, so that the stirring assembly can be immersed in the water, which has the functions of cleaning and preventing feed residues from solidifying. When the partition plate moves up and down to control the opening and closing of the orifice plate, the cleaning sleeve also moves up and down accordingly, facilitating the scraping of the materials on the surface of the stirring rod, thus achieving the effect of facilitating the cleaning of residual feed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0034] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0035] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , a feed stirring and mixing device based on an automatic feeding system, including a hopper 1 and a material control cylinder 2 fixedly installed at the bottom of the hopper 1. A transmission shaft 3 is rotatably installed inside the hopper 1, and a stirring assembly is installed at the bottom end of the transmission shaft 3. A driving motor 4 is fixedly installed on the surface of the hopper 1, and the driving motor 4 drives the transmission shaft 3 to rotate through belt transmission. For details, see Figure 4 .

[0036] Among them, the stirring assembly includes an orifice plate 23, the orifice plate 23 is rotatably installed inside the material control cylinder 2, and the bottom end of the transmission shaft 3 is fixedly connected to the orifice plate 23. Stirring rods 24 are fixedly installed on the upper surface of the orifice plate 23, as shown in Figure 5 .

[0037] A water supply pipe 5 is fixedly installed outside the hopper 1, and the outlet end of the water supply pipe 5 extends into the hopper 1. A liquid level gauge 6 is arranged inside the hopper 1.

[0038] A movable disk 7 is slidably installed inside the material control cylinder 2. An electric telescopic rod 8 is fixedly installed at the bottom of the material control cylinder 2, and the telescopic end of the electric telescopic rod 8 is fixedly connected to the bottom of the movable disk 7. A diversion pipe 9 is fixedly installed on the surface of the material control cylinder 2, and an overflow valve 27 is arranged on the surface of the material control cylinder 2.

[0039] Specifically, a partition plate 10 is fixedly arranged inside the hopper 1, and the liquid level gauge 6 is fixedly installed on the lower surface of the partition plate 10.

[0040] The partition plate 10 divides the inner cavity of the hopper 1 into a dry material chamber located on the upper side and a wet material chamber located on the lower side. A rotating disk 11 is rotatably installed on the upper surface of the partition plate 10. A plurality of material blocking arms 28 are fixedly installed inside the hopper 1, and the lower surface of the material blocking arms 28 is in sliding contact with the upper surface of the rotating disk 11.

[0041] A plurality of first flow holes 12 are formed on the surface of the rotating disk 11, and a plurality of second flow holes 13 are formed on the surface of the partition plate 10. The dry material chamber and the wet material chamber are communicated through the first flow holes 12 and the second flow holes 13, as shown inFigure 2 As shown, the dry feed is stored in the dry feed chamber of the hopper 1, and the dry feed is located on the upper side of the partition 10. When the rotating disk 11 rotates, the dry feed passes through the overlapping position of the first flow channel hole 12 and the second flow channel hole 13 and falls into the wet feed chamber on the lower side.

[0042] A control sleeve 14 is fixedly installed at the center of the partition 10, and the transmission shaft 3 passes through the rotating disk 11 and the control sleeve 14. A linkage component is arranged in the rotating disk 11. The control sleeve 14 drives the linkage component to rotate the rotating disk 11 and the transmission shaft 3. An electric pin 15 is arranged inside the partition 10. A pin hole 16 is opened on the surface of the rotating disk 11. The telescopic end of the electric pin 15 can be inserted into the pin hole 16 to constrain the angle of the rotating disk 11 when it stops rotating. Figure 4 As shown, the telescopic end of the electric pin 15 extends out and presses against the outer circumferential surface of the rotating disk 11 to slide. Finally, the telescopic end of the electric pin 15 is inserted into the pin hole 16. The angle at which the rotating disk 11 stops is just enough to completely stagger the first flow channel hole 12 and the second flow channel hole 13. Figure 4 At this time, the feed in the dry material chamber cannot fall into the wet material chamber below.

[0043] Among them, Figure 3 , Figure 6 As shown, the linkage assembly includes a lifting ring 17 and a magnetic ring 18. A guide rod 19 is fixedly installed on the surface of the lifting ring 17. The guide rod 19 is slidably inserted into the rotating disk 11. A support spring 20 is sleeved on the surface of the guide rod 19. The two ends of the support spring 20 are respectively fixedly connected to the rotating disk 11 and the lifting ring 17. The lifting ring 17 rotates with the rotating disk 11, but can move up and down.

[0044] A hexagonal sleeve 21 is fixedly installed on the surface of the transmission shaft 3, and a magnetic ring 18 is slidably installed on the surface of the hexagonal sleeve 21. The magnetic ring 18 can rotate with the transmission shaft 3. A hemispherical protrusion 22 is fixedly installed on the lower surface of the lifting ring 17, and a groove adapted to the hemispherical protrusion 22 is opened on the upper surface of the magnetic ring 18.

[0045] The surface sliding sleeve of the transmission shaft 3 is provided with a magnetic sleeve 25 , and a separation plate 29 is fixedly installed at the bottom end of the magnetic sleeve 25 . The separation plate 29 covers the upper surface of the orifice plate 23 and covers the holes on the surface of the orifice plate 23 .

[0046] In this embodiment, a first excitation coil 30 is embedded inside the top of the control sleeve 14. When the first excitation coil 30 is energized, the first excitation coil 30 generates an electromagnetic field that repels the magnetic ring 18. Figure 6, the magnetic ring 18 moves upward and abuts against the lifting ring 17. At this time, the rotating disk 11 rotates together with the transmission shaft 3. When it is necessary to stop the rotating disk 11 at a fixed angle, the first flow channel hole 12 and the second flow channel hole 13 are completely staggered, and the telescopic end of the electric pin 15 extends out until it is inserted into the pin hole 16, and the rotating disk 11 stops rotating. Because the first excitation coil 30 is powered off, the electromagnetic field generated by the first excitation coil 30 that repels the magnetic ring 18 gradually becomes smaller, ensuring that the rotating disk 11 stops delaying, so that the telescopic end of the electric pin 15 can be inserted into the pin hole 16, and the magnetic ring 18 and the lifting ring 17 can rotate relative to each other. The stop of the rotating disk 11 does not hinder the rotation of the transmission shaft 3.

[0047] Inside the bottom end of the control sleeve 14, a second excitation coil 31 is embedded. After the second excitation coil 31 is powered on, the second excitation coil 31 generates an electromagnetic field that attracts the magnetic sleeve 25. The magnetic sleeve 25 is subjected to an upward electromagnetic adsorption force, and the magnetic sleeve 25 moves upward. At this time, the partition disk 29 is separated from the orifice plate 23, as Figure 5 shown, the wet material in the wet material chamber of the hopper 1 can pass through the orifice plate 23 and enter the material control cylinder 2. Under normal conditions, the second excitation coil 31 is in a powered-off state, as Figure 7 shown, under the action of gravity, as well as the pressure of the material and water, the partition disk 29 covers the holes on the surface of the orifice plate 23.

[0048] In this embodiment, a cleaning sleeve 26 is slidably sleeved on the surface of the stirring rod 24. The cleaning sleeve 26 is fixedly connected to the partition disk 29. The top end of the cleaning sleeve 26 is in a conical structure. When the second excitation coil 31 is powered on and drives the partition disk 29 to move up and down to control the opening and closing of the orifice plate 23, the cleaning sleeve 26 moves up and down along the surface of the stirring rod 24, and the cleaning sleeve 26 can scrape the material on the surface of the stirring rod 24.

[0049] During use, there are multiple stirring and mixing devices proposed by the present invention, which are distributed above each feeding trough. The hopper 1 and the material control cylinder 2 are fixedly installed above the feeding trough through brackets. The outlet end of the diversion pipe 9 extends into the feeding trough. The automatic feeding system uses a tube chain conveyor as the feeding mechanism, and uses the tube chain conveyor to transport dry feed into the hopper 1 for temporary storage.

[0050] The stirring and mixing device proposed by the present invention has the following advantages for stirring feed:

[0051] (1) As Figure 8As shown, the height (H1 / H2) of the movable plate 7 is adjusted by the electric telescopic rod 8 to change the storage volume in the control barrel 2. Taking the case where the water supply pipe 5 injects water into the wet material chamber of the hopper 1 at a certain speed as an example, the dry feed in the hopper 1 falls into the wet material chamber, and the stirring component stirs and mixes it. The liquid level of the feed rises until the liquid level meter 6 is triggered. At this time, the water supply pipe 5 is cut off, the first excitation coil 30 is powered off, the telescopic end of the electric pin 15 can be inserted into the pin hole 16, the feed stops falling, and the stirring component continues to stir. Then, the movable plate 7 moves down to discharge the feed in the control barrel 2 into the feeding trough through the guide pipe 9. The controllable amount of feed is determined by the size of H1 / H2. The stirring and mixing device proposed by the present invention has the function of quantitative feeding, and each stirring and mixing device can be independently controlled to meet the needs of differentiated feeding.

[0052] (2) If Figure 8 As shown in the left figure, the stirring rod 24 moves in a circular motion to promote the feed to flow in layers, and the movable plate 7 moves up and down to promote the feed to flow in a vertical direction. The stirring and mixing device proposed by the present invention has the advantages of fast and uniform mixing speed, which greatly improves the mixing efficiency.

[0053] (3) When the amount of feed is large, it takes a long time to drop feed and inject water into the wet feed chamber of hopper 1. Figure 7 As described, the stirring and mixing equipment can first mix and process a certain amount of feed and introduce it into the feeding trough. During the process of introducing the feed into the feeding trough, water can be continuously added, material can be dropped and stirred in the wet material chamber of the hopper 1. Then, the partition plate 29 is controlled to move up and separate from the orifice plate 23. The material in the wet material chamber of the hopper 1 can pass through the orifice plate 23 and enter the material control cylinder 2. The present invention realizes the functions of batch stirring and continuous discharging, shortens the waiting time, and can well ensure the temperature of the feed in the feeding trough, especially in seasons with low temperatures. The stirring and mixing equipment proposed in the present invention has the advantage of fast discharging speed. It should be noted that the stirring and mixing equipment proposed in the present invention does not need to be provided with a heat preservation mechanism itself, which makes the equipment simpler and reduces the manufacturing cost. When it is necessary to strictly control the temperature of the fed feed, it is only necessary to add a heat preservation layer to the water supply pipe 5. For a large automatic feeding system, this method is easier to implement.

[0054] The stirring and mixing equipment proposed by the present invention controls the feeding speed of the wet material chamber of the hopper 1 by the rotation speed of the rotating disk 11. The operating speeds of both the rotating disk 11 and the stirring assembly are controlled by the driving motor 4. When the feeding amount increases, the stirring speed also increases accordingly, so that the feed falling into the water in the wet material chamber of the hopper 1 is quickly stirred and dispersed, which can prevent the situation that the stirring speed cannot keep up with the change due to the increase in the feeding amount, resulting in the feed agglomerating, seriously affecting the mixing speed and even causing blockage. Livestock need to be fed with feeds of different viscosities at different growth stages. This design adjusts the viscosity of the feed by regulating the rotation speed of the driving motor 4 to meet the needs of differential feeding, providing conditions for the remote linkage control of the automatic feeding system. Here, the viscosity of the feed, for example, a large viscosity specifically refers to less water added and more dry feed input, and a small viscosity specifically refers to more water added and less dry feed input.

[0055] The stirring and mixing equipment proposed by the present invention performs wet material treatment above the feeding trough (the end of the automatic feeding system). That is, the dry feed is conveyed in the tube chain conveyor of the automatic feeding system, solving the problems of easy residue and difficult cleaning of the wet feed conveyed in the tube chain conveyor.

[0056] In addition, as Figure 8 shown in the left figure, when the movable disk 7 moves to the top of the material control cylinder 2, only a small amount of water needs to be injected into the wet material chamber of the hopper 1, so that the stirring assembly can be immersed in the water, which has the functions of cleaning and preventing feed residue from solidifying. The partition disk 29 moves downward. At this time, the soaking water in the wet material chamber of the hopper 1 can be drained away from the overflow valve 27. When the partition disk 29 moves up and down to control the opening and closing of the orifice plate 23, the cleaning sleeve 26 also moves up and down accordingly, facilitating scraping the materials on the surface of the stirring rod 24, so as to achieve the effect of facilitating the cleaning of the residual feed.

[0057] By using this stirring and mixing equipment to add water and stir the feed, according to actual needs, the prepared wet feed is quantitatively put into each feeding trough. The materials in each material control cylinder 2 can be adjusted and controlled manually, and the feed amounts conveyed to the feeding troughs are different, having the function of differential feeding. During the use process, the materials conveyed in the tube chain conveyor are dry feeds. Compared with wet feeds, the residual dry feeds in the tube chain conveyor have a longer storage time and are not easy to breed bacteria. Moreover, the inner cavities of the hopper 1 and the material control cylinder 2 can be washed or soaked by injecting water, and the cleaning is also convenient. The stirring and mixing equipment proposed by the present invention can meet the use requirements of the automatic feeding system for point-by-point feed stirring and feeding.

[0058] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent replacements or changes, should be covered by the protection scope of the present invention.
