Description

A large-scale chicken farm feed mixing device Technical Field

[0001] This invention relates to the field of feed mixing for resource recovery, specifically to a feed mixing device for large-scale chicken farms. Background Technology

[0002] In the chicken farming industry, there are often chicken feeds that involve resource recycling. This refers to the reprocessing of food industry by-products, agricultural residues, or waste into components of chicken feed. This practice not only reduces feed costs and environmental pollution but also aligns with the concept of a circular economy. The main sources of chicken feed involving resource recycling are food processing by-products, such as: distiller's grains and vinegar residues: grain residues left after brewing beer, spirits, and rice vinegar (such as dried distiller's grains and their solubles). Rich in protein and fiber, they are excellent sources of energy and protein; fruit pomace: apple pomace, citrus pomace, grape seeds / skins, etc., left after juice extraction. Rich in fiber and sugar, they can be used as part of an energy feed after drying; soybean residue: a by-product of making tofu and soy milk, high in protein but high in moisture, requiring timely drying or fermentation to prevent spoilage; and kitchen waste: solids extracted from leftover food in restaurants or canteens after strict treatment such as high-temperature sterilization, desalination, degreasing, and sterilization.

[0003] In large-scale chicken farms, drugs need to be added to feed made from recycled resources. In large-scale farming, drugs are usually added to prevent diseases (by adding them continuously at low doses) or to treat diseases (by adding them in pulses at higher doses).

[0004] However, conventional feed has a more uniform particle size, making it easier to mix medications. But recycled feed ingredients can have significantly different particle sizes (e.g., distillers' grains are coarse, while blood meal is fine), requiring a higher degree of carrier uniformity. Furthermore, some recycled ingredients (such as fermented straw powder or fruit pomace containing high fiber or lignin) have strong adsorption properties. They may adsorb medications (such as antibiotics and vitamins), preventing effective release of the drugs in the chicken's intestines and thus reducing efficacy.

[0005] Therefore, using existing mixing equipment to add medication to these chicken feeds can lead to difficulties in mixing, resulting in reduced efficacy, complete drug failure, or excessive dosage. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a feed mixing device for large-scale chicken farms, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a large-scale chicken farm feed mixing device, comprising an adjustable outer shell assembly, and further comprising an outer stirring assembly, an inner dispensing assembly, and a planetary drive assembly installed within the adjustable outer shell assembly. The outer stirring assembly is rotatable relative to the adjustable outer shell assembly, and the inner dispensing assembly is located within the outer stirring assembly and is rotatable relative to the outer stirring assembly. The planetary drive assembly is used to drive both the outer stirring assembly and the inner dispensing assembly. The planetary drive assembly can achieve the following: the inner dispensing assembly rotates while the outer stirring assembly remains stationary; the inner dispensing assembly and the outer stirring assembly rotate synchronously; the inner dispensing assembly and the outer stirring assembly rotate at different speeds; the inner dispensing assembly remains stationary while the outer stirring assembly rotates.

[0008] Preferably, the external stirring assembly includes a stirring tank, with a closed joint fixedly installed at both ends of the stirring tank. The end of the closed joint away from the stirring tank is installed on the side wall of the adjustable outer shell assembly and rotatably connected to it. The closed joint at the first end has a feed inlet, and the closed joint at the last end has a discharge outlet. The inner wall of the stirring tank has a barrier strip that occupies half of the stirring tank and is close to the closed joint at the last end of the stirring tank.

[0009] Preferably, the internal drug delivery assembly includes an inner tube with a mesh on the outside. Both ends of the inner tube are fixedly installed with shrink tubes. The two shrink tubes pass through the middle of two closed joints and are rotatably connected to them. The inner wall of the inner tube is equipped with a spiral baffle strip, and the outer wall of the inner tube is fixedly installed with a spiral pusher strip. The outer side of the spiral pusher strip extends to the inner wall of the mixing tank, and the spiral pusher strip is located on the other side of the corresponding baffle strip.

[0010] Preferably, the planetary drive assembly includes a servo motor, a sun gear, planet gears, and an external gear ring. The sun gear is fixedly sleeved on the shrink tube. Multiple planet gears are provided, and their axles are all connected to the side of the closed joint. The external gear ring is rotatably connected to the side wall of the adjustable housing assembly. The sun gear, planet gears, and external gear ring mesh with each other. Two servo motors are provided, both fixed on the adjustable housing assembly. One servo motor is used to drive the sun gear, and the other servo motor is used to drive the external gear ring.

[0011] Preferably, the output shaft of the servo motor is fixedly mounted with gears, and the outer gear ring has teeth on both the inner and outer sides. The teeth of the inner ring mesh with the planetary gears, the teeth of the outer ring mesh with the gears, and the other gear meshes with the sun gear.

[0012] Preferably, the adjustable outer casing assembly includes an inner box, a bottom beam, a hydraulic cylinder, and a feed head. The mixing tank is housed within the inner box and rotatably connected to it. The servo motor and the external gear ring are both mounted on the side wall of the inner box. The bottom beam is located at the bottom of the inner box, with one end of the inner box rotatably connected to the tail end of the mixing tank. The two ends of the hydraulic cylinder are rotatably connected to the inner box and the bottom beam, respectively. The extension of the hydraulic cylinder can lift one end of the inner box, thereby lifting the head end of the mixing tank. The feed head is installed at the upper end of the inner box, corresponding to the position of the closed joint feed inlet. The feed head has an elastic structure, and when subjected to downward force, its lower end can be inserted near the feed inlet. A discharge joint is installed on the inner box corresponding to the discharge port.

[0013] Preferably, the internal drug delivery assembly further includes a drug delivery tube, which is mounted on the inner casing. The end of the retractable tube away from the inner tube has a flared structure, allowing the drug delivery tube to be inserted into the retractable tube.

[0014] Preferably, it also includes an outer casing, with the inner casing installed inside the outer casing.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The large-scale chicken farm feed mixing device, by setting an internal drug delivery component and an external stirring component, places the feed in the external stirring component and the drug delivery component in the internal drug delivery component. When the stirring tank rotates, it can mix the chicken feed, and the drug in the inner tube will be evenly dispersed with the rotation of the inner tube, and then evenly spread in the stirring tank with the movement of the inner tube. Therefore, even if the carrier particle size is uneven, the recycled feed in the stirring tank can achieve a relatively balanced drug mixing.

[0016] 2. This large-scale chicken farm feed mixing device, through the setting of a planetary drive component, allows for multiple motion modes between the inner tube and the mixing tank. When the inner tube rotates while the mixing tank does not, chicken feed can be added in the early stage and evenly distributed in the mixing tank. When the inner tube and the mixing tank rotate at different speeds, the medicine can be evenly spread on the feed in the mixing tank. When they rotate at the same speed or the mixing tank rotates alone, they can be mixed or fed separately. Unlike traditional feed mixers, this device separates the medicine from the chicken feed in the early stage, making it less likely to cause local clumping and excessively high drug concentration.

[0017] 3. This large-scale chicken farm feed mixing device, by setting an adjustable outer shell component, allows the chicken feed to be discharged by tilting the inner box after the chicken feed mixed with medicine has been processed. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0022] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0024] As shown in Figures 1-10, a large-scale chicken farm feed mixing device includes an adjustable outer shell assembly 1, and further includes an outer stirring assembly 2, an inner dispensing assembly 3, and a planetary drive assembly 4 installed inside the adjustable outer shell assembly 1. The outer stirring assembly 2 can rotate relative to the adjustable outer shell assembly 1, and the inner dispensing assembly 3 is located in the outer stirring assembly 2 and can rotate relative to the outer stirring assembly 2. The planetary drive assembly 4 is used to drive the outer stirring assembly 2 and the inner dispensing assembly 3 respectively. The planetary drive assembly 4 can achieve the following: the inner dispensing assembly 3 rotates while the outer stirring assembly 2 does not rotate; the inner dispensing assembly 3 and the outer stirring assembly 2 rotate synchronously; the inner dispensing assembly 3 and the outer stirring assembly 2 rotate at different speeds; the inner dispensing assembly 3 does not rotate while the outer stirring assembly 2 rotates.

[0025] When mixing medication, three key points need to be clarified first: Confirm the medication plan: a prescription must be issued by a licensed veterinarian, specifying the name of the medication, dosage (usually expressed in milligrams per kilogram of body weight or grams per ton of feed), and withdrawal period; Accurately calculate the dosage: Formula: Total dosage = Total weight of flock (kg) × Recommended dosage (mg / kg) ÷ Effective drug content (%). Distinguish between treatment and preventative dosages. Treatment dosages are usually higher and require continuous feeding for 3-5 days; After confirming the feed-to-medication ratio, mix the feed in the external mixing component 2, while the internal medication component 3 is mainly used to prevent medication from entering. The relative rotation of the two components disperses the medication into the external mixing component 2. The planetary drive component 4 provides the power for their rotation. The planetary drive component 4 has roughly three motion forms, resulting in three effects: Internal medication component 3 rotates, external mixing component 2 does not rotate: In this state, external feed can be added to the external mixing component 2. The added feed tends to accumulate in one area, so the rotation of the internal medication component 3 disperses the accumulated feed until the measured amount of feed is completely incorporated into the external mixing component 2.

[0026] The internal drug delivery component 3 and the external stirring component 2 rotate synchronously: In this state, the drug has been delivered into the internal drug delivery component 3. When the external stirring component 2 rotates, the drug will tumble. However, there is no speed difference between the external stirring component 2 and the internal drug delivery component 3, so the drug simply rolls. At this time, the drug in the internal drug delivery component 3 will be spread evenly on the feed, resulting in a uniform planar distribution.

[0027] The internal drug delivery component 3 and the external stirring component 2 rotate at different speeds. In this state, there is a speed difference between the two, so the feed is tumbled more violently, and the drug is continuously delivered and has basically been delivered. At this time, the drug and feed have been mixed and are being continuously stirred.

[0028] The internal drug dispensing component 3 does not rotate, while the external stirring component 2 rotates. This indicates that the drug has been released. The feed in the external stirring component 2 performs the final mixing work and keeps the feed rolling continuously to ensure that the drug particles are completely broken up and evenly attached to the feed, making it easy to pour out.

[0029] In an optional embodiment, the external stirring assembly 2 includes a stirring tank 201. Both ends of the stirring tank 201 are fixedly installed with a sealing joint 202. The end of the sealing joint 202 away from the stirring tank 201 is installed on the side wall of the adjustable outer shell assembly 1 and rotatably connected thereto. The sealing joint 202 at the first end is provided with a feed inlet 203, and the sealing joint 202 at the last end is provided with a discharge outlet 204. The inner wall of the stirring tank 201 is provided with a barrier strip 205, which occupies half of the stirring tank 201 and is close to the sealing joint 202 at the last end of the stirring tank 201.

[0030] In this embodiment, the sealing joint 202 is used to seal both ends of the mixing tank 201 to prevent the feed from moving out, so that the feed can only be discharged from the discharge port 204. The feed inlet 203 is equipped with a one-way baffle, which will open inward when subjected to force. When the mixing tank 201 rotates, the protruding baffle strip 205 inside it will provide a certain tumbling force to the feed. The sealing joint 202 is connected to the adjustable outer shell assembly 1 by a large bearing and provides support for rotation.

[0031] In an optional embodiment, the internal drug delivery assembly 3 includes an inner tube 301 with a mesh 302 on its outer surface. Both ends of the inner tube 301 are fixedly installed with shrink tubes 303. The two shrink tubes 303 pass through the middle of two closed joints 202 and are rotatably connected to them. The inner wall of the inner tube 301 is equipped with a spiral baffle 304, and the outer wall of the inner tube 301 is fixedly installed with a spiral push bar 305. The outer side of the spiral push bar 305 extends to the inner wall of the mixing tank 201, and the spiral push bar 305 is located on the other side of the corresponding baffle bar 205.

[0032] In this embodiment, the mesh 302 of the inner tube 301 is combined with the requirements of the diameter of the drug particles. The constriction tubes 303 at both ends of the inner tube 301 are used for drug inlet and outlet. The mesh 302 can also further screen the drug particles. Drug particles exceeding a certain diameter can be discharged again from the constriction tube 303.

[0033] The spiral baffle 304 of the inner tube 301 can disperse the drug when it rotates, so that the drug is opened and evenly distributed in the inner tube 301. Compared with the prior art, there is an additional step of preliminary drug treatment, which is carried out simultaneously with the mixing of feed.

[0034] In an optional embodiment, the planetary drive assembly 4 includes a servo motor 401, a sun gear 402, planet gears 403, and an external gear ring 404. The sun gear 402 is fixedly sleeved on the shrink tube 303. Multiple planet gears 403 are provided, and their axles are all connected to the side of the closed joint 202. The external gear ring 404 is rotatably connected to the side wall of the adjustable housing assembly 1. The sun gear 402, planet gears 403, and external gear ring 404 mesh with each other. Two servo motors 401 are provided, both fixed to the adjustable housing assembly 1. One servo motor 401 drives the sun gear 402, and the other servo motor 401 drives the external gear ring 404.

[0035] In this embodiment, the large bearing mentioned above is also installed on the outer side of the external gear ring 404 to achieve the effect of supporting rotation. When setting up, in order to increase the smoothness of transmission, the number of planetary gears 403 is set to four, and their axles are evenly distributed on the closed joint 202. When installing, the sun gear 402 is in the middle, the planetary gears 403 are distributed in a circle, and the external gear ring 404 is on the outermost side, forming a meshing state.

[0036] The servo motor 401 used for control is driven by a servo board and can provide various effects such as limiting rotation and controlling rotation speed.

[0037] In an optional embodiment, the output shaft of the servo motor 401 is fixedly mounted with gears 405. The outer gear ring 404 has teeth on both the inner and outer sides. The teeth of the inner ring mesh with the planet gears 403, and the teeth of the outer ring mesh with the gears 405. Another gear 405 meshes with the sun gear 402.

[0038] In this embodiment, the servo motor 401 combined with the gear 405 can not only provide rotational force, but also provide a reaction force to prevent rotation.

[0039] In an optional embodiment, the adjustable outer casing assembly 1 includes an inner housing 101, a bottom beam 102, a hydraulic cylinder 103, and a feed head 104. A mixing tank 201 is disposed within and rotatably connected to the inner housing 101. A servo motor 401 and an external gear ring 404 are both mounted on the side wall of the inner housing 101. The bottom beam 102 is located at the bottom of the inner housing 101, with one end of the inner housing 101 rotatably connected to the bottom beam 102 corresponding to the tail end of the mixing tank 201. Both ends of the hydraulic cylinder 103 are rotatably connected to the inner housing 101 and the bottom beam 102, respectively. Extension of the hydraulic cylinder 103 can lift one end of the inner housing 101, thereby lifting the head end of the mixing tank 201. The feed head 104 is installed at the upper end of the inner housing 101, corresponding to the position of the feed inlet 203 of the closed connector 202. The feed head 104 is an elastic structure; when subjected to downward force, its lower end can insert into the vicinity of the feed inlet 203. The inner box 101 is equipped with a discharge connector 105 at the position corresponding to the discharge port 204.

[0040] In this embodiment, the inner box 101 is a closed structure. Under different actual application conditions, electronic components such as heating coils, temperature sensors, and humidity sensors can be installed inside to monitor the feed temperature and maintain temperature and humidity. The bottom beam 102 supports the inner box 101. When the mixing tank 201 is relatively short, the first end of the mixing tank 201 can be kept slightly lower than the last end during the initial mixing when the hydraulic cylinder 103 is not in operation. This way, the feed will not be discharged from the last end while the mixing tank 201 is mixing the feed. However, when the mixing tank 201 is longer, this angle can be set to be smaller, just enough to ensure that the feed does not flow out from the discharge port 204.

[0041] In an optional embodiment, the internal drug delivery assembly 3 further includes a drug delivery tube 306 mounted on the inner casing 101. The end of the retractable tube 303 away from the inner tube 301 has a flared structure, and the drug delivery tube 306 can be inserted into the retractable tube 303.

[0042] In this embodiment, the dosing tube 306 is used to combine liquid drugs with existing technology, which can achieve the effect of directly pumping to the middle of the inner tube 301, or it can be connected to a pipeline for pumping granular drugs.

[0043] In an optional embodiment, an outer housing 5 is also included, with an inner housing 101 installed inside the outer housing 5.

[0044] In this embodiment, the outer casing 5 serves to protect the equipment and also houses electrical components, and its end is equipped with a safety door.

[0045] In use, chicken feed that needs to be mixed with the medication is first fed through the feed head 104. At this time, the servo motor 401 drives the mixing tank 201, so that the feed inlet 203 at the end of the mixing tank 201 faces upward and corresponds to the feed head 104. The chicken feed fed through the feed head 104 will enter the mixing tank 201. At the same time, the servo motor 401 drives the inner tube 301 to rotate. When the inner tube 301 rotates, the spiral bar 305 evenly distributes the feed inside the mixing tank 201. Then, the medication is added into the inner tube 301. The servo motor 401 is controlled to keep the outer gear ring 404 stationary and the sun gear 402 rotating. At this time, the inner tube 301 and the mixing tank 201 rotate at different speeds. At this time, the medicine can be dispersed and evenly sprinkled on the chicken feed. When the mixing tank 201 rotates, it can mix and stir the chicken feed. The medicine is mixed into the chicken feed at this time. The baffle strip 205 set inside the mixing tank 201 can tumble the feed. Then, by controlling two servo motors 401, the inner tube 301 and the mixing tank 201 can be rotated at the same time to achieve a further tumbling effect. Before feeding, controlling the outer gear ring 404 to rotate can achieve only the mixing tank 201 to rotate. The medicine and feed are mixed in the last step before feeding. Finally, the hydraulic cylinder 103 is controlled to extend to lift the mixing tank 201 and the outer box 5. The medicine can be discharged from the discharge port 204 of the closed joint 202.
