Description

Technical Field

[0001] The invention relates to the field of livestock feeding systems, and in particular to an integrated system for feeding and dosing liquid feed for pigs. Background Art

[0002] In the current large-scale pig farming enterprises, the use of liquid feed for breeding has gradually become the development direction. Compared with dry feed, liquid feeding is not easy to produce dust, and will not cause health problems such as anorexia, respiratory diseases, and digestive tract diseases in the pig herd; on the other hand, liquid feed is easier for pigs to absorb, and pigs are easier to fatten, thus achieving the goal of maximizing benefits.

[0003] At present, the mainstream products of liquid feed use the mode of centralized mixing and centralized transportation to each pig pen. Each mixing and transportation generally covers 1 to 4 pig houses, about 500 to 1500 fattening pigs. The total amount of liquid feed fed each time ranges from 1000kg to 5000kg. Liquid feed is made by mixing dry feed + water. In the actual feeding process, in addition to the above-mentioned dry feed and water, some vitamins, drugs and other agents will be added according to the actual situation of the pigs. The total amount of these agents that need to be added is generally only 1‰ to 2‰ of the total amount of liquid feed. However, due to the huge amount of liquid feed, the supporting adding equipment used for liquid feed has relatively low precision, and the speed of adding dry feed and water to the mixing tank is fast. Therefore, if the liquid feed batching system is used to add agents, it is difficult to meet the accuracy of the agent content, thereby affecting the growth and development of pigs. Summary of the invention

[0004] The present invention aims to provide an integrated system for feeding and dosing liquid feed for pigs, so as to solve the problem that it is difficult to meet the accuracy of drug content in the prior art.

[0005] To achieve the above object, the present invention adopts the following technical solution: a pig liquid feed feeding and drug administration integrated system, comprising:

[0006] The weighing unit comprises at least two weighing mechanisms for weighing the medicine powder and the medicine liquid respectively, the weighing mechanism comprises a weighing hopper and a weighing device installed in the weighing hopper, and the lower part of the weighing hopper is connected to a medicine discharge pipe;

[0007] The mixing unit includes a mixing barrel, which is installed below the weighing hopper. The medicine discharge pipe is connected to the mixing barrel, which is also connected to a clean water delivery pipe. A stirring mechanism is installed in the mixing barrel, and an output pipe is connected to the bottom of the mixing barrel, which is connected to a pump for pumping the mixed medicine in the mixing barrel.

[0008] The pump machine is connected with a medicine delivery pipe, and the medicine delivery pipe is provided with a plurality of delivery branches respectively connected to each pig pen, and the delivery branch pipes are connected with electromagnetic valves.

[0009] The principles and advantages of this solution are: to solve the problem that the proportion of the medicine to liquid feed in the prior art is too small, so that when the medicine is added using the liquid feed batching system, the accuracy of the medicine content cannot be met, thereby affecting the growth and development of pigs. Therefore, this solution sets up a separate integrated drug delivery system to accurately weigh the medicine and stir and mix it. During the mixing process, clean water is added through a clean water delivery pipe, which on the one hand allows the medicine to be fully mixed, and on the other hand facilitates pumping by the pump. In addition, in this solution, the weighing of powder and liquid medicines is refined and classified to avoid the mixing and adhesion of dry and wet medicines, which affects the discharge of the medicine and the accuracy of the medicine weighing.

[0010] By implementing this plan, the dosage of the medicine can be accurately administered, thereby ensuring the good growth and development of pigs.

[0011] Secondly, in the actual feeding process, not all pigs need to add medicines, but they are added in different pens according to the growth and development of the pigs in each pen. Therefore, a plurality of delivery branches connected to each pig pen are provided on the medicine delivery pipe, and solenoid valves are connected to the delivery branches. In this way, when it is necessary to add medicines to some pigs in need, it is only necessary to open the solenoid valve of the corresponding pig pen to achieve independent delivery in each pen.

[0012] Preferably, as an improvement, a flow guide cover is coaxially sleeved on the medicine discharge pipe of the powder weighing unit, and flow guide holes are opened in the circumference of the flow guide cover. The flow guide holes located on the uppermost layer are at least 5 cm away from the outlet of the medicine discharge pipe. An isolation cover is connected to the outer surface of the flow guide cover, and one side of the isolation cover is connected to the clean water delivery pipe.

[0013] Preferably, as an improvement, the guide holes are arranged along the guide cover, tilted downward from outside to inside, and the relative guide holes are staggered.

[0014] Preferably, as an improvement, the bottom of the air guide cover is coaxially connected to a rotating disk, the rotating disk includes a central axis and a circular ring, a plurality of diverter plates are connected between the central axis and the circular ring, the plurality of diverter plates are all inclined along the same circumferential direction; the guide holes located in the lower layer are all inclined along the same circumferential direction, and the inclination direction is opposite to the inclination direction of the diverter plates, and the extension line of the axis of the guide hole is located on the diverter plate.

[0015] Preferably, as an improvement, the stirring mechanism comprises at least two lightweight stirring rods, and the lightweight stirring rods are connected to the ring or the diverter plate.

[0016] Preferably, as an improvement, a cleaning hole for cleaning the outlet of the medicine discharge pipe is provided on the upper portion of the deflector, and the cleaning hole is arranged obliquely toward the direction of the medicine discharge pipe.

[0017] Preferably, as an improvement, the lightweight stirring rod is circular and hollow inside. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is further described in detail through specific implementation methods:

[0023] The figure marks in the drawings of the specification include: weighing hopper 1, mixing barrel 2, medicine discharge pipe 3, clean water delivery pipe 4, stirring mechanism 5, guide cover 6, guide hole 7, isolation cover 8, guide cavity 9, central axis 10, ring 11, diverter plate 12, bracket 13, lightweight stirring rod 14, cleaning hole 15.

[0024] Example 1

[0025] This embodiment is basically as shown in the attached Figure 1 Shown: Pig liquid feed feeding and dosing integrated system, including:

[0026] The weighing unit includes two weighing mechanisms for weighing the medicine powder and the medicine liquid respectively. The weighing mechanism includes a weighing hopper 1 and a weighing device installed at the bottom of the weighing hopper 1. The weighing device adopts a weighing sensor in the prior art. The weighing hopper 1 is connected to a medicine discharge pipe 3.

[0027] The mixing unit includes a mixing barrel 2, which is located below the weighing mechanism. A medicine discharge pipe 3 is connected to the mixing barrel 2. A clean water delivery pipe 4 is also connected to the side wall of the mixing barrel 2. A stirring mechanism 5 is installed at the bottom of the mixing barrel 2. The stirring mechanism 5 includes a motor. A stirring shaft is connected to the output shaft of the motor. The motor is installed outside the mixing barrel 2. The stirring shaft extends into the mixing barrel. The stirring shaft and the mixing barrel are connected by bearings and sealed (sealing technology is a common technology in the prior art and will not be described here). A pump is provided at the bottom of the mixing barrel 2 for pumping the mixed liquid in the mixing barrel 2 to each pig pen.

[0028] The weighing hopper 1, the mixing barrel 2, the mixer 5 and the pump are all fixed on the frame.

[0029] In this solution, a separate integrated drug delivery system is provided to accurately weigh the medicine and stir and mix it. During the mixing process, clean water is added through the clean water delivery pipe 4, which not only fully mixes the medicine but also facilitates pumping by the pump. In addition, in this solution, the weighing of powder and liquid medicine is finely classified to avoid the mixing and agglomeration of dry and wet medicines, which affects the discharge of the medicine and the accuracy of the medicine weighing.

[0030] Among them, the pump is connected to a medicine delivery pipe, and the medicine delivery pipe is connected to each pig pen through a delivery branch pipe. In this solution, the delivery branch pipe is connected to the delivery branch pipe of the liquid material, so that the medicine can be put into the corresponding pig pen together with the liquid material, which is conducive to the pigs' feeding. The delivery branch pipe is connected to a solenoid valve. In the actual feeding process, not all pigs need to add medicine, but they are added in different pens according to the growth and development of the pigs in each pig pen. Therefore, through the above settings, the pigs that need to add medicine only need to control the opening of the solenoid valve of the corresponding pig pen to achieve independent delivery.

[0031] Example 2

[0032] like Figure 2 As shown, in this embodiment, a guide cover 6 is coaxially sleeved on the medicine discharge pipe 3 of the weighing mechanism of the powder, and the guide cover 6 is detachably connected to the outlet of the medicine discharge pipe 3, and can be threaded or clamped. In this scheme, threaded connection is selected. A plurality of guide holes 7 are opened on the circumference of the guide cover 6, and the guide holes 7 are arranged downwardly from the outside to the inside along the guide cover 6, and the relative guide holes 7 are staggered. The guide holes 7 located at the top layer are at least 5 cm away from the outlet of the medicine discharge pipe 3, and an isolation cover 8 is coaxially fixedly sleeved on the outside of the guide cover 6, and a guide cavity 9 is formed between the isolation cover 8 and the guide cover 6, and the clean water delivery pipe 4 is installed on one side of the isolation cover 8 and communicated with the guide cavity 9.

[0033] In Example 1, since the medicine discharge pipe 3 of the medicine powder is connected to the mixing barrel 2, it is found in actual operation that most of the agglomerated medicine powder blocks always remain on the outlet of the medicine discharge pipe 3. On the one hand, these residual medicine powder blocks are easy to breed bacteria, which increases the risk of disease in some pigs in special stages (such as sows that have just given birth and pigs in the recovery period); on the other hand, when changing the medicine for pigs with different symptoms, the residual medicine powder blocks may be opposite to or counteract the next medicine, which will cause other problems.

[0034] Therefore, the applicant analyzed the reasons for the agglomeration of the above-mentioned powders, because during or after the discharge of the powders, the discharge of the liquid medicine and clean water and the stirring process, the liquid will splash onto the outlet of the medicine discharge pipe 3 of the powders, causing the liquid and the powders to adhere and agglomerate. In order to avoid the agglomeration phenomenon, the applicant connected the medicine discharge pipe 3 of the powders to the top of the mixing barrel 2. Although this method solves the problem of powder agglomeration well, the powders cause dust flying during the discharge process, making the environment of the entire batching workshop poor and affecting the health of the workers.

[0035] In summary, this scheme is designed. By implementing this scheme, the clean water delivery pipe 4 is opened at the same time when discharging the powder. The water in the clean water delivery pipe 4 enters the guide cavity 9 through the isolation cover 8, and is sprayed into the guide cover 6 after passing through multiple guide holes 7 to impact and mix with the powder. On the one hand, the preliminary mixing of the powder is achieved; on the other hand, the problem of dust flying is avoided after the mixed powder is discharged from the guide cover 6; the most important thing is that no powder agglomeration will occur at the outlet of the medicine discharge pipe 3 or on the guide cover 6. The specific reason is: the uppermost guide hole 7 is at least 5 cm away from the outlet of the medicine discharge pipe 3, and the guide holes 7 are all arranged downwardly from the outside to the inside along the guide cover 6, and the relative guide holes 7 are staggered, so it is difficult for clean water to splash onto the medicine discharge pipe 3; at the same time, since the ratio of powder to water is usually greater than 1:20, after the powder is discharged, the clean water will continue to be discharged from the guide cover 6, so that the inner wall of the guide cover 6 can be rinsed to avoid the problem of powder sticking to the wall.

[0036] Among them, a cleaning hole 15 for cleaning the outlet of the medicine discharge pipe 3 is opened in the circumference of the upper part of the deflector 6. The cleaning hole 15 is located above the outlet of the medicine discharge pipe 3 and is inclined toward the medicine discharge pipe 3. The cleaning hole 15 is connected to a pipeline and a valve is set. A small booster pump can be added to the pipeline according to actual conditions. The cleaning hole 15 and the clean water delivery pipe 4 are both connected to the same water source. Through the above arrangement, even if the medicine powder is adhered to the outlet of the medicine discharge pipe 3 during the discharge process, the valve of the cleaning hole 15 can be opened to flush it.

[0037] Example 3

[0038] like Figure 3 , 4 As shown, based on Example 2, this embodiment has a rotating disk coaxially connected to the bottom of the air guide cover 6, the rotating disk includes a central axis 10 and a ring 11, the ring 11 is rotatably connected to the air guide cover 6 through a bearing, a plurality of diverter plates 12 are fixedly connected between the central axis 10 and the ring 11, all of the diverter plates 12 are inclined in the same circumferential direction; the guide holes 7 located in the lower layer are all inclined in the same circumferential direction, and the inclination direction is opposite to the inclination direction of the diverter plates 12, and the extension line of the axis of the guide holes 7 is located on the diverter plates 12.

[0039] The purpose of setting the diverter sheet 12 in this scheme is to impact and disperse some of the drug powders that agglomerate when they encounter water; in addition, all the diverter sheets 12 are tilted in the same circumferential direction, which is not only more convenient for the drug powders mixed with water to flow, but more importantly: the clean water can impact the diverter sheet 12, causing the rotating disk to rotate, and the rotating diverter sheet 12 can centrifuge part of the medicine so that part of the mixed medicine rotates and part falls linearly, so that the medicine forms turbulence in the mixing barrel 2, thereby making the drug powder and clean water mixed more evenly. The degree of mixing under this method can basically meet the mixing requirements of most categories of drugs, so for easily mixed and easily soluble drugs, there is no need to start the stirring mechanism 5 for stirring and mixing.

[0040] Therefore, by implementing this embodiment, not only the problem of drug powder agglomeration and drug powder flying is solved, but also the basic mixing effect is achieved, and there is no need to start the stirring mechanism 5 for mixing except in special circumstances.

[0041] In another embodiment, the rotating disk can also be connected in a rotating manner: three brackets 13 are fixedly connected to the upper part of the central shaft 10, and the free ends of the brackets 13 are fixed to the inner wall of the air guide cover 6. The ring 11 includes an inner ring 11 and an outer ring 11, and the inner ring 11 is rotatably connected to the central shaft 10, and a plurality of flow diverters 12 are fixed between the inner ring 11 and the outer ring 11. The advantage of this rotating connection method is that the rotating disk rotates more lightly and smoothly, and rotates faster.

[0042] Example 4

[0043] The difference from Example 1 is that the stirring mechanism in this embodiment includes three lightweight stirring rods 14, and the lightweight stirring rods 14 are connected to the ring 11 or the diverter plate 12, so that when the rotating disk rotates, the lightweight stirring rods 14 can be driven to stir the medicine in the mixing barrel 2 to make the medicine fully mixed. In order to reduce the weight of the stirring mechanism 5 and make the turntable easier to rotate, the lightweight stirring rods 14 are designed to be circular and hollow inside. The lightweight stirring rods 14 are made of lightweight materials, such as TPEE, TPX, aluminum alloy, etc. In addition, a small booster pump can be installed on the clean water delivery pipe 4 according to actual conditions to increase the impact of water pressure on the turntable.

[0044] With the above arrangement, there is no need to additionally arrange a stirrer 5 at the bottom of the mixing barrel 2, so as to reduce maintenance costs and cleaning difficulty.

[0045] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
