Description

Technical Field

[0001] The invention relates to the technical field of feeding systems, in particular to a precise feeding system for water-mixed feed. Background Art

[0002] In the process of pig farming, feeding porridge is an effective method that can significantly improve the appetite of pigs. Porridge is made by mixing dry feed with water, which can provide more abundant moisture and nutrition and promote digestion and absorption of pigs. However, the shelf life of feed is closely related to its dry state, so when preparing feed, you must be careful not to mix dry feed with water too early, which can effectively extend the storage time of feed and avoid mildew or nutrient loss caused by moisture.

[0003] For large-scale pig farms, the scale of feeding is huge, and it is usually necessary to provide food for nearly a thousand pigs in one feeding. In this case, the transportation of porridge becomes a challenge. Since the fluidity of porridge is poor and it is difficult to effectively transport it through the pipeline system, farms usually choose to centrally mix dry feed with water, and then manually put the mixed porridge into each feeding trough one by one.

[0004] However, the mixing process is not easy to carry out in the feeding trough. Once the feed is placed in the feeding trough, pigs often do not wait patiently for mixing, but start eating immediately. In this case, the use of the mixing mechanism may cause pig injuries because the space between the mixing equipment and the pigs is very limited in the narrow feeding trough. Therefore, when designing the feeding system, it is necessary to fully consider the safety and comfort of the pigs to ensure that the feed can be evenly distributed while avoiding any harm to the pigs. Through reasonable management and technical means, the health and safety of the pigs can be guaranteed while improving feeding efficiency. Summary of the invention

DETAILED DESCRIPTION

[0043] 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.

[0044] Example 1

[0045] Reference Figure 1-Figure 6 .

[0046] A water-mixed feed precision feeding system, comprising a feeding trough 1,

[0047] A feeding system 2 for conveying dry powder feed toward the feeding trough 1;

[0048] The feeding system 2 has a feeding pipe 21, which is located above the feeding trough 1, and a screening cylinder 22 is provided at the discharge end of the feeding pipe 21;

[0049] A sieve plate 221 is provided in the sieve cylinder 22, and the diameter of the sieve cylinder 22 is larger than the diameter of the drop tube 21;

[0050] The mixing system 3 comprises: a mixing cylinder 31 arranged at the discharge end of the screening cylinder 22, and both ends of the mixing cylinder 31 are connected;

[0051] and an atomizing spraying device 32 for spraying water mist toward the mixing cylinder 31;

[0052] The jet device 34 delivers water flow toward the feeding trough 1, and the water flow forms a water flow drop point 4 in the feeding trough 1, and the water flow drop point 4 is located directly below the discharge end of the drop pipe 21;

[0053] The control system starts the feeding system 2 , the mixing system 3 , and the jet device 34 and determines the flow rates of the atomizing spray device 32 and the jet device 34 according to the feeding amount of the feeding system 2 .

[0054] Feed needs to be stored for a long time, so the feed needs to be kept dry to extend the shelf life. However, pigs prefer to eat porridge, that is, dry feed mixed with water. Therefore, when raising pigs, personnel will first use dry feed to add water to make porridge, and then feed the prepared porridge to the pigs. For large pig farms, all feeding uses an automated system. Dry feed and water are easy to transport, but porridge is difficult to transport, and the porridge is difficult to clean up after accumulating in the conveying pipeline, and it is very easy to mold. Therefore, in the prior art, large pig farms only pour dry feed and water into the feeding trough 1, and will not fully mix. Dry feed is easy to clump and float on the water surface, etc., and it is not in full contact with water. Therefore, manual mixing is still required. It is difficult to set a stirring mechanism in the feeding trough 1 to replace manual mixing, because when the feed is poured into the feeding trough 1, the pigs will start to eat quickly, and the stirring mechanism movement is very easy to injure the pigs. In addition, the stirring mechanism has many mechanical structures such as joints and blades, and the porridge is difficult to clean when it is adhered.

[0055] In this regard, the present application provides a water-mixed feeding system, which uses water to replace a stirring mechanism to complete the preparation of porridge.

[0056] The feeding system 2 includes a feeding pipe 21. The powdered feed enters the feeding pipe 21 and falls into a screening drum 22 at the bottom of the feeding pipe 21. A sieve plate 221 is arranged inside the screening drum 22. A motion mechanism such as a vibration module can be arranged between the feeding pipe 21 and the screening drum 22 to continuously shake off the feed. The sieve holes of the sieve plate 221 are not very fine small holes like a sieve, but large holes that are very easy for feed to pass through, with a diameter of about 0.5cm-2cm. The sieve plate 221 blocks the falling of the feed, prevents a whole lump of feed from falling instantly, and allows the feed to continuously float into the mixing system 3.

[0057] The mixing system 3 includes a mixing drum 31 and an atomizing spray device 32. The atomizing spray device 32 continuously sprays water mist into the mixing drum 31. After the feed enters the mixing drum 31, it is fully in contact with the water mist. At this time, the feed forms a slurry. The inside of the slurry feed is completely moistened. There will be no caking of dry feed by directly adding water, and the dry feed will not float on the water surface. The slurry feed falls vertically into the feeding trough 1 due to gravity, and then the jet device 34 transports water flow into the feeding trough 1. The water flow forms a water flow landing point 4 in the feeding trough 1. The water flow disperses the slurry feed to simulate the stirring action. The dry feed and water are fully mixed, and finally a uniform porridge material is formed.

[0058] The control system specifically includes a main controller, which can control the feeding amount of dry feed by controlling the speed and time of screening materials or controlling the amount of feed entering the drop pipe 21. Flow sensors are set in the pipelines of the atomizing spray device 32 and the jet device 34 to deliver water in a corresponding proportion according to the feeding amount of dry feed. The main controller can feed at a preset time, or set a trigger device near the feed trough to wait for the pig to activate the trigger device before feeding.

[0059] More specifically, a storage tank 25 is provided above the drop pipe 21;

[0060] A horizontally arranged auger conveyor 26 is provided below the storage tank 25;

[0061] Feed is transported between the storage tank 25 and the drop pipe 21 via the auger conveyor 26 .

[0062] A storage tank 25 is arranged above the drop tube 21, and a sufficient amount of dry feed is stored in the storage tank 25. The auger conveyor 26 is commonly used for conveying granules and powder materials. The feed is pushed forward by the internal auger, and the auger pushes the feed to the outlet, and the feed falls into the drop tube 21.

[0063] More specifically, the atomizing spray device 32 includes a plurality of atomizing spray heads surrounding the mixing drum 31, and the atomizing spray heads spray water mist toward the axis of the mixing drum 31;

[0064] The jet device 34 includes a plurality of jet nozzles surrounding the mixing cylinder 31;

[0065] The atomizing nozzle and the jet nozzle are both fixed to the mixing barrel 31 through a bracket 35;

[0066] Moreover, the height position of the jet nozzle is located between the blocking plate 33 and the atomizing nozzle. The atomizing spray device 32 and the jet device 34 use independent pipelines and pump groups.

[0067] Example 2

[0068] Reference Figure 4 and Figure 5 .

[0069] A rotating scraper 222 is disposed in the screening cylinder 22, and the edge of the rotating scraper 222 is in contact with the screening plate 221;

[0070] A first driving component 223 is further disposed in the screening drum 22 to drive the rotating scraper 222 to rotate around the axis of the screening drum 22 .

[0071] This embodiment provides a more preferred material screening method and structure.

[0072] The dry feed falls on the sieve plate 221. If the sieve hole is very small, the feed is easily blocked. Therefore, vibration and other methods are required to generate relative motion between the feed and the sieve plate 221 to allow the feed to continue to fall. The most common way to sieve is to shake the sieve plate 221. This is also the most common movement mode when sieving things in daily life. However, when there is too much backlog of feed above the sieve plate 221, the feed at the bottom and the sieve plate 221 are very tightly abutted. Simple shaking and vibration are difficult to cause relative motion between the feed at the bottom and the sieve plate 221, and will make the bottom feed more and more compact. Of course, if the aperture of the sieve plate 221 is large enough, the above problems will not occur. However, the larger the aperture, the more concentrated the feed falls. The closer the feed falls to a flowing state, the more difficult it is for the water mist to fully contact all the feed, and the feed cannot form a slurry feed in the mixing barrel 31. Therefore, it is necessary to ensure that the feed can be continuously shaken off when the diameter of the sieve hole is small.

[0073] In this regard, a rotating scraper 222 is provided in the present embodiment, and the rotating scraper 222 is driven to rotate around the axis of the screening barrel 22 by a first driving component 223, i.e., a motor. The scraper pushes some feed to rotate when rotating, and the feed moves relative to the sieve plate 221 during the rotation process, which effectively prevents feed blockage. The rotating scraper 222 only pushes the feed at the bottom, so it will not shake the feed above, which causes the feed to become compact and difficult to push due to excessive accumulation of feed.

[0074] Furthermore, a hemispherical protrusion 224 is provided above the rotating scraper 222 , and the hemispherical protrusion 224 is coaxial with the screening drum 22 ; a gap L3 is formed between the bottom surface of the hemispherical protrusion 224 and the screening plate 221 , and 7 cm>L3>3 cm.

[0075] The hemispherical protrusion 224 above the rotating scraper 222 supports part of the feed, reducing the feed moved by the rotating scraper 222. The bottom surface of the hemispherical protrusion 224 and the sieve plate 221 form a spacing L3, forming a part of the cavity, so that the feed has a certain movement space. When the rotating scraper 222 rotates, a large part of the feed will roll into the space after being squeezed, making the feed looser and less prone to blockage. In addition, the hemispherical protrusion 224 is a spherical surface, and the resistance of the feed during rotation is very small, and the rotating scraper 222 will also save more effort when pushing a small amount of feed, thereby reducing the strength requirements for the rotating scraper 222 and the requirements for the first drive component 223. In particular, the first drive component 223 is difficult to use a high-power motor because the first drive component 223 needs to be set in the screening barrel 22 and the volume is limited.

[0076] Example 3

[0077] Reference Figure 3 and Figure 4 .

[0078] The mixing system 3 further includes a blocking plate 33 disposed below the discharge end of the mixing barrel 31, wherein the diameter of the blocking plate 33 is greater than the diameter of the mixing barrel 31;

[0079] The blocking plate 33 is fixedly connected to the mixing drum 31 via a plurality of cantilevers, and the blocking plate 33 maintains a distance L1 from the discharge end of the mixing drum 31, 15 cm> L1> 5 cm;

[0080] The water flows toward the baffle plate 33 .

[0081] The water flow is injected into the mixing drum 31 to mix with the slurry feed once, and then mixed again when falling into the feeding trough 1. However, both of them move by their own gravity, and the contact time of the two during the movement is very short. In addition, the water flow is relatively concentrated and it is difficult to contact a large area of ​​feed. This results in a general mixing effect of the two, and it is not possible to form a uniform porridge in time when the feed enters the feeding trough 1.

[0082] In this embodiment, a blocking plate 33 is provided below the discharge end of the mixing barrel 31, and the diameter of the blocking plate 33 is larger than the diameter of the mixing barrel 31. That is to say, the feed in the mixing barrel cannot pass through the blocking plate 33 due to gravity, and the blocking plate 33 receives the slurry feed, which is static at this time, and external force is required to transfer the feed to the feeding trough 1. At this time, the jet device 34 delivers water toward the blocking plate 33, flushing the feed horizontally and falling into the feeding trough 1.

[0083] The blocking plate 33 is connected to the mixing drum 31 by a cantilever, and a distance L1 is maintained between the blocking plate 33 and the outlet of the mixing drum 31. The value of L1 can be in the range of 5 cm to 15 cm, so that the feed impacted by the water flow can flow out through the position of the distance L1 without being blocked.

[0084] Furthermore, the middle area of ​​the blocking plate 33 is a conical blocking surface 331, and the edge area is a horizontal blocking surface 332; the apex of the conical blocking surface 331 faces the mixing barrel 31, and the bottom diameter of the conical blocking surface 331 is greater than the diameter of the mixing barrel 31;

[0085] The jet device 34 sprays water toward the apex of the conical blocking surface 331 .

[0086] It is not possible to set too many nozzles for the jet device 34, and two or three nozzles are sufficient, otherwise it will lead to problems such as too many parts, difficult maintenance, and high cost. However, the proportion of feed is fixed, and the jet device 34 cannot spray a large amount of water. The cross-sectional area of ​​the water flow is very small, so the coverage area of ​​two or three water flows is limited, which is far less than the bearing area of ​​the blocking plate 33, which makes it difficult for the water flow to ensure that the feed is completely washed down.

[0087] In this regard, in this embodiment, a large area in the middle of the blocking plate 33 is set as a conical blocking surface 331, and a small area on the edge is kept horizontal and set as a horizontal blocking surface 332. The apex of the conical blocking surface 331 faces the mixing drum 31. When the slurry feed falls, it is mainly received by the conical blocking surface 331. The feed on the conical surface is easier to slide than on the horizontal surface. Therefore, the water flow only needs a smaller force to wash away the feed, and the feed on the conical blocking surface 331 can fall by its own gravity. It is only because the friction between itself and the conical blocking surface 331 is greater than the downward force that prevents it from falling. Therefore, as long as the water flow can weaken the friction of the feed, it is sufficient to make the feed fall.

[0088] However, in this embodiment, the blocking plate 33 is not just the conical blocking surface 331. The edge area of ​​the blocking plate 33 still retains the horizontal blocking surface 332 to prevent the slurry feed below from rolling down directly when the water flow just touches the top of the conical blocking surface 331. It still plays a role in preventing the feed from falling directly only by its own gravity, and ensures that the feed can only flow down with a certain impact force provided by the water flow (the impact force of the water flow flowing down from the top of the conical blocking surface 331 is sufficient).

[0089] Example 4

[0090] Reference Figure 1 , Figure 3 as well as Figure 4 .

[0091] The mixing cylinder 31 is slidably connected to the screening cylinder 22;

[0092] The outer wall surface of the discharge end of the screening cylinder 22 is provided with a circle of annular scrapers 225, and the annular scrapers 225 are in contact with the inner wall of the mixing cylinder 31;

[0093] The outer wall surface of the screening cylinder 22 is fixedly connected with a second driving component 226, and the second driving component 226 drives the mixing cylinder 31 to slide to a working end close to the feeding trough 1 or a storage end away from the feeding trough 1.

[0094] The dry feed is combined with the water mist in the mixing barrel 31, and it is inevitable that the feed will adhere to the inner wall of the mixing barrel 31. The mixing barrel 31 is different from the feeding trough 1. The feeding trough 1 is located on the ground and is easy to clean, while the mixing barrel 31 is located at a high place and is not convenient to clean. If the adhered wet feed is not cleaned in time, it will soon become moldy and deteriorate. In addition, the water mist sprayed by the atomizing spray device 32 has a very small mass and a very small impact force. Even if the next feeding is done, the wet feed adhered during the previous feeding process cannot be washed away.

[0095] In this application, an annular scraper 225 is provided on the outer wall surface of the port of the drop tube 21, and the annular scraper 225 is attached to the inner wall of the mixing barrel 31, and the mixing barrel 31 is slidably connected with the drop tube 21. When the mixing barrel 31 is fully extended, the mixing barrel 31 is at the working end. When the mixing barrel 31 is completed after feeding, the mixing barrel 31 is retracted in time. During the retraction process, the annular scraper 225 is stationary, and the mixing barrel 31 moves upward, so the two move relative to each other. The annular scraper 225 can scrape the slurry feed on the inner wall surface of the mixing barrel 31 and drop it to the blocking plate 33. In this process, dry feed is no longer fed, but the jet device 34 continues to deliver water to wash off the feed falling on the blocking plate 33.

[0096] The annular scraper 225 protrudes from the mixing drum 31 at the receiving end, completely scrapes out the feed in the mixing drum 31, and the jet nozzle moves with the mixing drum 31, and the jet nozzle can wash the annular scraper 225. Two or three jet nozzles may not be enough to fully wash the annular scraper 225. A spiral guide rail can be set on the outer wall of the mixing drum 31, and then the second driving component 226 drives a screw sleeve to rotate, thereby driving the mixing drum 31 to spirally rise, so as to wash the annular scraper 225 at different angles.

[0097] Example 5

[0098] Reference Figure 1 , Figure 2 as well as Figure 5

[0099] The screening cylinder 22 is movably connected to the drop tube 21 via a telescopic tube 23. The drop tube 21 is provided with a third driving component 24 to drive the screening cylinder 22 so that the bottom surface of the blocking plate 33 at the working end position forms a distance L2 with the bottom surface of the feeding trough 1;

[0100] 30cm>L2>20cm.

[0101] During feeding, the porridge falls directly from a great height, causing the porridge to splash everywhere. However, if the blocking plate 33 is too close to the feeding trough 1, the hungry pigs will gnaw and push the blocking plate 33, destroying the sliding fit between the mixing cylinder 31 and the screening cylinder 22, as well as the cantilever of the blocking plate 33, thereby affecting the normal operation of the system.

[0102] In this embodiment, the screening drum 22 and the drop tube 21 are movably connected by a telescopic tube 23, and the telescopic tube 23 can be a corrugated tube, a multi-section tube, etc. The screening drum 22 is driven by the third driving component 24, and the screening drum 22 and the mixing drum 31 are kept away from the feeding trough 1 in time after the feeding is completed. In addition, in this embodiment, after the third driving component 24 drives the screening drum 22 to approach the feeding trough 1, there is still a distance L2, 30cm>L2>20cm, so that the porridge material maintains a short falling distance, and the porridge material is further mixed by the impact when it falls.

[0103] Furthermore, the bottom surface of the feeding trough 1 has a diversion slope 11; the water flow drop point 4 is formed in the diversion slope 11;

[0104] The guide slope 11 forms an angle a with the horizontal plane; the opening of the angle a faces the outside of the feeding trough 1, 90°>a>45°.

[0105] A guide slope 11 is provided on the bottom surface of the feeding trough 1. When the porridge material falls, the guide slope 11 controls the splashing direction of the porridge material. When the liquid falls on the wall in the vertical falling direction, it will splash in the direction of 45° around, and when it falls on the 45° slope, the splashing direction will be rotated 45°.
