Description

Technical Field

[0001] This invention relates to technical solutions related to the feeding process in sheep farming, specifically a precision nutrition feeding system and method for sheep during pregnancy and lactation. Background Technology

[0002] Scientific management of nutrition during the gestation and lactation periods of meat sheep is crucial for ensuring the health of ewes, improving lamb survival rates, and promoting later growth. During the later stages of pregnancy, the fetus grows rapidly (70% of birth weight is achieved in the last six weeks), and milk production during lactation requires a large amount of energy. Insufficient nutrition can lead to ewes consuming their own fat and muscle, resulting in rapid weight loss and metabolic disorders. Calcium and phosphorus deficiencies can easily cause postpartum paralysis, and long-term phosphorus deficiency can also reduce conception rates. Deficiencies in vitamins A and E, zinc, and selenium can weaken the ewe's disease resistance and increase the risk of postpartum infection. Furthermore, insufficient nutrition can also hinder lamb development. Malnutrition during pregnancy leads to low birth weight, incomplete organ development, and reduced survival rates in lambs. Insufficient maternal milk results in slow growth, lower weaning weight, and even death due to starvation or poor immunity. Therefore, when feeding meat sheep during the gestation and lactation periods, in addition to the precise ratio of conventional energy and protein feeds, it is necessary to add minerals or vitamins to supplement the feed, increasing the sheep's nutritional intake and ensuring that both the ewe and the lambs receive sufficient nutrition.

[0003] In sheep farming, the feed mainly consists of roughage and concentrate. Roughage primarily refers to hay, straw, and green fodder, which constitute the main daily ration and provide basic satiety. Concentrate mainly refers to energy feeds such as corn, barley, and wheat, and protein feeds such as soybean meal and rapeseed meal. It mainly supplements the sheep with protein and energy, promoting their growth, fattening, and reproduction. It needs to be supplemented precisely according to the sheep's growth stage and needs, and should not be excessive. In addition, nutritional supplements tailored to the sheep's growth stage are also essential, such as salt, bone meal, and vitamins.

[0004] The structure of a sheep's feed varies depending on its growth stage, especially during the gestation and lactation periods. The required nutrient intake at each stage should be adjusted accordingly, meaning the necessary minerals and vitamins should be tailored to the ewe's gestation and lactation stages. The feed ratio can also be adjusted based on the sheep's specific growth condition. Nutrients are primarily obtained from concentrates, which are then added to the concentrate. Concentrates are typically pelleted for sheep consumption. However, adding nutrients to these pellets presents a significant challenge: these nutrients are usually in powder form, while concentrate raw materials are generally granular. This necessitates a high degree of mixing between the concentrate raw materials and nutrient components. Otherwise, uneven distribution of nutrients within the pellets can lead to insufficient homogeneous intake and absorption by the sheep. Conventional granulation equipment mainly refers to roller granulators. Roller granulators are effective for granulating granular raw materials such as corn, barley, and wheat. During the extrusion process, heat is generated to mature the granules. Furthermore, the granulation process denatures trypsin inhibitors in grains and legumes, reducing adverse effects on digestion. It also kills various parasite eggs and other pathogenic microorganisms, reducing the risk of parasitic infections and digestive system diseases. However, roller granulators struggle to achieve complete homogenization of powder and granules during granulation. Existing equipment rarely includes pre-mixing facilities for granules and powder. The structural characteristics of granules and powder cause powder to easily fall to the bottom of the granules during mixing, making it difficult to achieve the desired uniformity. Currently, the best method is to crush the granules before mixing them with the nutrient components for granulation. However, when using powder for granulation, the temperature is difficult to reach the desired maturation temperature, making this maturation process challenging. Moreover, this process requires crushing and mixing the raw materials, making it relatively cumbersome. Therefore, from a holistic perspective, if roller pelleting equipment can be used to pelletize raw materials and ensure the uniform mixing of granular raw materials and powdered nutrient components, it will have far-reaching significance for the precise nutrition feeding of meat sheep. Summary of the Invention

[0005] This invention relates to a precision nutrition feeding system for pregnant and lactating sheep. It is designed with a structure that mixes nutrients with granular materials, and combines it with a roller pellet mill to form a direct forming process from raw materials to finished pellets. In addition, this invention also provides a method for using the feeding system.

[0006] The present invention adopts the following technical solution: A precision nutrition feeding system for pregnant and lactating sheep includes a pelleting section, a feed hopper, and a homogenizing section located between the pelleting section and the feed hopper. The feed hopper is connected to the pelleting section and conveys materials into the pelleting section. The homogenizing section is located between the feed hopper and the pelleting section. The homogenizing section disperses powdered nutrient components. During the process of the material in the feed hopper entering the pelleting section, the nutrient components are dispersed into the pelleting section and rolled into pellets together with the material.

[0007] The hopper is arranged in a ring shape above the granulation section. The corresponding material enters the granulation section in a ring-shaped manner. The homogenizing section is located at the center of the ring-shaped area formed by the falling material. The homogenizing section is a vertical tubular structure. Powdered nutrient components are put into the homogenizing section, and the bottom of the homogenizing section is provided with a corresponding mechanism to disperse the powdered nutrient components inside it horizontally to the outside.

[0008] The homogenizing section includes an annular storage cylinder with a funnel-shaped feed hopper at the top. The bottom of the storage cylinder has vertically evenly distributed through-holes. The bottom of the storage cylinder also has a discharge plate that seals its bottom surface. The discharge plate has a rotating structure at the bottom of the storage cylinder and a discharge groove that extends horizontally to its outer edge. When the discharge plate rotates, the discharge groove rotates and intersects with the slots in sequence. Nutrient components enter the discharge groove from the storage cylinder through the slots and then flow out of the homogenizing section from the side through-hole of the discharge groove.

[0009] Furthermore, a sliding sleeve is provided at the center of the storage cylinder, a drive motor is provided at the top of the sliding sleeve, and a rotating shaft is provided above the center of the discharge plate. The rotating shaft passes through the sliding sleeve, and the upper end of the rotating shaft is connected to the drive motor. The drive motor drives the rotating shaft and the discharge plate at the bottom to rotate.

[0010] Furthermore, the slots are strip-shaped structures, and are evenly distributed in a ring on the bottom plate between the sliding sleeve and the cylinder wall of the storage cylinder, with the slots penetrating vertically on the bottom plate; the bottom plate is also provided with evenly distributed air grooves, which are staggered with the slots, and the air grooves penetrate horizontally through the lower half of the bottom plate. The inner diameter of the sliding sleeve is larger than the diameter of the rotating shaft on the discharge plate, and the rotating shaft is provided with a support ring that supports the inner wall of the sliding sleeve, and the support ring is provided with a grid for gas to pass through; the inner side of the air groove is connected to the space between the sliding sleeve and the rotating shaft, and the sliding sleeve is also provided with an air inlet pipe that maintains communication with its interior.

[0011] Furthermore, the hopper includes a cylindrical section and a feeding section. The cylindrical section has a cylindrical structure, and the feeding section has an inverted conical structure. The cylindrical section is connected to the top of the feeding section to form the hopper. The top of the granulation section is provided with a conical cover plate, which is connected to the bottom of the feeding section. The hopper and the cover plate form an hourglass-shaped structure. The homogenization section is located at the center of the hopper and extends downward into the cover plate.

[0012] Furthermore, a conical material distribution plate is provided at the center of the top of the cover plate, and the four sides of the material distribution plate are connected to the bottom of the cover plate by connecting plates; the top of the material distribution plate is connected to the lower part of the storage cylinder, and the bottom of the homogenization section corresponds to the inner side of the material distribution plate.

[0013] The granulation unit includes a shell and pressure rollers disposed inside the shell. A perforated plate is provided at the center of the shell, and a drive shaft driven by a drive motor is provided at the center of the shell and the perforated plate. Two pressure rollers symmetrically mounted on the drive shaft above the perforated plate are mounted on the left and right sides. A discharge hopper is provided at the bottom of the shell.

[0014] The silo is also equipped with several fan-shaped distribution silos. The inner and outer sides of the distribution silos are supported by the top of the feed hopper and the cylindrical part, respectively. The distribution silos form a ring structure around the homogenizing part in the silo. The bottom of the distribution silos is equipped with an electronically controlled discharge port with metering function.

[0015] A method for using a precision nutrition feeding system for pregnant and lactating sheep involves setting up a corresponding number of feed bins in the feed silo according to the raw material composition of the concentrated feed. Then, each raw material is put into the corresponding feed bin, and the powdered nutrient to be added is added to the storage cylinder of the homogenizing section through the feed hopper. During the pelleting process, the ratio of raw materials entering the pelleting section is adjusted by controlling the electrically controlled feed inlet as needed, and the amount of powdered nutrient to be added is adjusted by controlling the speed of the drive motor of the homogenizing section.

[0016] The present invention, by adopting the above technical solution, has the following beneficial effects: The addition of a homogenizing section in this device enables the continuous addition and mixing of powdered nutrient raw materials. Compared to grinding all raw materials into powder before mixing and granulation, this method greatly improves ease of use. This device directly realizes the heating and maturation process in the granulation operation, and it also achieves uniform mixing and granulation of granular and powdered raw materials, preventing uneven distribution of nutrient raw materials in the finished granules during the granulation process.

[0017] Furthermore, the homogenization section of this device employs a pneumatic structure to blow nutrients, which allows for better dispersion of materials within the granular raw materials, thereby achieving uniformity in the final product and ensuring that sheep receive precise nutritional supplementation during feeding. Finally, the multi-component silos and the central homogenization section in this device can be controlled by programming in actual use, thereby realizing automated proportioning. By controlling the electronically controlled discharge port and the speed of the drive motor, the proportion of raw materials and the proportion of added nutrients can be adjusted, thus facilitating automated control and operation.

[0027] like Figures 1-7 The system shown is a precision nutrition feeding system for pregnant and lactating sheep. It includes a pelleting section 1, a feed hopper 2, and a homogenizing section 3 located between the pelleting section 1 and the feed hopper 2. The feed hopper 2 is connected to the pelleting section 1 and conveys materials into the pelleting section 1.

During the process of the material in the feed hopper 2 entering the pelleting section 1, the nutrient components are dispersed into it and rolled into pellets together with the material.

[0028] The hopper 2 is arranged in a ring shape above the granulation section 1. The corresponding material enters the granulation section 1 in a ring-shaped manner.

Nutrient components enter the discharge groove 305 from the storage cylinder 301 through the slots 303, and then flow out of the homogenizing section 3 from the side through-hole of the discharge groove 305.

[0030] Furthermore, a sliding sleeve 306 is provided at the center of the storage cylinder 301, a drive motor 307 is provided at the top of the sliding sleeve 306, and a rotating shaft 308 is provided above the center of the discharge plate 304.

The drive motor 307 drives the rotating shaft 308 and the discharge plate 304 at the bottom to rotate.

[0031] Furthermore, the slots 303 are strip-shaped structures, and are evenly distributed in a ring on the bottom surface between the sliding sleeve 306 and the cylinder wall of the storage cylinder 301, with the slots 303 extending vertically through the bottom surface. The bottom surface of the storage cylinder 301 is also provided with evenly distributed air grooves 309, which are staggered with the slots. The air grooves 309 extend laterally through the lower half of the bottom surface. The inner diameter of the sliding sleeve 306 is larger than the diameter of the rotating shaft 308 on the discharge plate 303. The rotating shaft 308 is provided with a support ring 310 that supports the inner wall of the sliding sleeve 306, and the support ring 310 is provided with a grid for gas to pass through. The inner side of the air grooves 309 communicates with the space between the sliding sleeve 306 and the rotating shaft 308. The sliding sleeve 306 is also provided with an air inlet pipe 311 that maintains communication with its interior.

[0032] Furthermore, the hopper 2 includes a cylindrical part 201 and a feeding part 202. The cylindrical part 201 has a cylindrical structure, and the feeding part 202 has an inverted conical structure. The cylindrical part 201 is connected to the top of the feeding part 202 to form the hopper 2. The top of the granulation part 1 is provided with a conical cover plate 101. The cover plate 101 is connected to the bottom of the feeding part 202. The hopper 2 and the cover plate 101 form an hourglass-shaped structure. The homogenizing part 3 is located at the center of the hopper 2 and extends downward into the cover plate 101.

[0033] Furthermore, a conical material distribution plate 102 is provided at the top center of the cover plate 101, and the four sides of the material distribution plate 102 are connected to the bottom of the cover plate 101 through the connecting plate 103; the top of the material distribution plate 102 is connected to the lower part of the storage cylinder 301, and the bottom of the homogenizing part 3 corresponds to the inner side of the material distribution plate 102.

[0034] The granulation unit 1 further includes a housing 104 and pressure rollers 105 disposed inside the housing 104. A perforated plate 106 is provided at the center of the housing 104. A drive shaft 108 driven by a drive motor 107 is provided at the center of the housing 104 and the perforated plate 106. Two pressure rollers 105 are mounted symmetrically on the drive shaft 108 above the perforated plate 106. A discharge hopper 109 is provided at the bottom of the housing 104.

[0035] The hopper 2 is also provided with several fan-shaped distribution hoppers 203. The inner and outer sides of the distribution hoppers 203 are respectively supported to the top of the feed hopper 302 and the cylindrical part 201. The several distribution hoppers 203 form a ring structure around the homogenizing part 3 in the hopper 2. The bottom of the distribution hoppers 203 is provided with an electronically controlled discharge port 204 with metering function.

[0036] This invention also describes a method for using a precision nutrition feeding system for pregnant and lactating sheep. The system involves setting up a corresponding number of feed distribution bins 203 within the feed silo 2 according to the composition of the concentrated feed. Each raw material is then fed into its corresponding feed distribution bin 203. The powdered nutrient to be added is then fed into the storage cylinder 301 of the homogenizing section 3 via the feed hopper 302. During granulation, the ratio of raw materials entering the granulating section 1 is adjusted by controlling the electrically controlled feed inlet 204 as needed. Simultaneously, the amount of powdered nutrient to be added is adjusted by controlling the rotation speed of the drive motor 307 of the homogenizing section 3.

[0037] The innovation of this device lies in its ability to directly granulate powdered additives with granular raw materials without crushing them, and to ensure that the powdered additives are evenly dispersed in the whole granules, so that all sheep can eat concentrated feed containing nutrients.

[0038] The working principle of the homogenization operation in the homogenization section is that the nutrients are stored in the storage cylinder outside the bushing. When the drive motor rotates, it drives the discharge plate at the bottom to rotate. During the process, when the discharge chute corresponds to the slot, the material enters the discharge chute from the slot. At this time, the air supply from the air inlet pipe to the bushing will not affect the material in the discharge chute. When the discharge plate rotates to the bottom of the air slot, the nutrients in the discharge chute are sent out along the air slot as the air flow in the bushing flows outward. The nutrients are scattered with the air flow into the material falling from the hopper, and then they are extruded and granulated together in the granulation section.

[0039] Even when the discharge chute is not aligned with the air chute, the air chute continues to supply air to the granulation section, accelerating the airflow within the granulation section and allowing the powder and granules to mix better and more evenly. The distribution plate can disperse the material falling from the hopper and guide the powder dispersed from the homogeneous part, ensuring that it makes full contact with the material dispersed at the distribution plate.
