Description

Technical Field

[0001] The invention relates to the technical field of animal nutrition and feed production, in particular to a milky nutrient solution preparation injection device and an injection method for promoting animal lactation and fattening. Background Art

[0002] China is a country with a large population and a large livestock industry. The improvement of people's living standards calls for the development of the livestock industry. In 2023, China's cattle breeding volume will reach 105.0851 million heads, the number of live pigs will reach 434.22 million heads, the number of sheep will reach 322.33 million heads, the pork production will reach 57.94 million tons, the poultry production will reach 25.63 million tons, an increase of 1.2 million tons over the previous year, the beef production will reach 7.53 million tons, the mutton production will reach 5.31 million tons, the milk production will reach 41.97 million tons, and the egg production will reach 35.63 million tons.

[0003] After animals eat feed, part of it is digested and absorbed by the gastrointestinal tract, enters the liver for metabolism, and synthesizes animal fat, protein and milk in the body, while part of it cannot be digested and absorbed and is excreted in the form of feces. In the process of digestion and absorption of feed in the gastrointestinal tract, a certain amount of energy is often consumed. In production practice, due to the limited or restricted gastrointestinal volume of animals, animals often cannot eat too much feed, which makes it difficult for animals to exert their maximum production performance, especially lactating cows and lactating sows. In order to increase the milk production of lactating cows and lactating sows, people try their best to increase the feed intake of lactating cows and lactating sows. However, it is often difficult to significantly increase the feed intake of lactating cows and lactating sows. Therefore, if the complete nutrition of feed can be injected into the blood without entering the gastrointestinal tract and directly reaching the liver for metabolic synthesis, it can not only reduce the energy consumption of gastrointestinal nutrient absorption, but also improve animal production performance.

[0004] Therefore, we propose a milky nutrient solution preparation injection device and injection method for promoting animal lactation and fattening to solve the above problems. Summary of the invention

[0041] 1. Emulsified instant intravenous emulsified complete nutrient solution is rich in bioactive nutrients such as homogenized emulsified soy protein, homogenized emulsified fat powder, maltodextrin, glucose, calcium, phosphorus, and complex vitamins. It contains not only fat and protein, but also carbohydrates, minerals and vitamins, which can quickly supplement complete nutrition for animals. It has the characteristics of high emulsified fat content, high soluble protein content, high maltodextrin content, low glucose content, aseptic purification, low anti-nutritional factor content, and good effect in promoting animal lactation and fattening. It can effectively make up for the nutritional deficiencies of animals in their natural feeding state, and the injected nutrients do not require the animal's own digestion and absorption ability, and directly enter the blood, quickly supplementing nutrition for animals, promoting lactation, accelerating fattening, and greatly improving animal production performance.

[0042] 2. By connecting the device inlet with the stirring tank, the initial flow meter accurately measures the raw material flow, providing a basis for subsequent precise allocation. The detection hose simulates the fluid mechanics environment in the body. Different inner diameters and bending settings promote full mixing of the raw materials, improve the uniformity of the mixed liquid, and provide animals with nutrient solution with stable ingredients. The detection hose not only achieves mixing, but also can perform preliminary quality inspection on the mixed substances.

[0043] 3. The change of tube diameter and the curved structure can filter and block impurities, ensure the purity of the nutrient solution delivered to the animals, reduce health problems caused by impurities, select the corresponding diameter detection hose according to different animal species and weight, optimize the mixing effect and detection accuracy, and meet the special needs of different animals for nutrient solution. For example, small-diameter detection hoses are suitable for animals with small body size and fast metabolism, which helps to improve the mixing speed and detection sensitivity and ensure the animal's nutrient absorption.

[0044] 4. Check the flow meter and compare the initial flow meter data to confirm the accuracy and stability of the nutrient solution flow during the preparation process. The cyclic detection mechanism, through the three-way pipe, solenoid valve and return pipe, ensures that the quality and uniformity of the prepared nutrient solution are in the best state, improving the safety and effectiveness of the nutrient solution used by animals.

[0045] 5. When the inner diameter of the detection hose is changed, the device works together through the servo motor, gear transmission and feeding components to achieve accurate docking of the injection pipe with the new detection hose. The first return spring, the second return spring and the piston ring and other components ensure the stability of the docking while preventing the leakage of high-viscosity raw materials, ensuring the stable operation of the device and meeting the needs of different animals for nutrient solution.

The feed elbow 9 includes a main pipe, a bent pipe and a straight pipe, and the main pipe is inserted in the sealing plate 5, and its center line coincides with the center line of the sealing plate 5, and the straight pipe does not coincide with the center line of the sealing plate 5, and the bent pipe is connected between the main pipe and the straight pipe, and the feed assembly is installed at the lower end of the straight pipe;

[0120] The inlet of the device is connected to the discharge port of the stirring tank through a pipeline. The raw materials of the emulsified nutrient solution first pass through the initial flow meter 4 connected to the upper end of the feed elbow 9. The initial flow meter 4 accurately measures the flow of the raw materials entering the device. After the servo motor 3 is started, its output shaft drives the driving gear 15 to rotate. The driving gear 15 engages with the transmission gear 11 installed outside the feed elbow 9, thereby driving the feed elbow 9 to rotate, so that the feed assembly connected to the lower end of its straight pipe rotates, and the injection pipe 13 in the feed assembly slides on the annular cover 10, and the injection port 23 is aligned with the feed hole 19 in turn, and the raw materials that have been preliminarily measured are accurately transported to the detection hose 8.

[0121] The detection hose 8 has different inner diameters and is curved. This unique design simulates the complex fluid mechanics environment in the body. When different raw materials enter the detection hose 8, the flow rate and flow direction of the raw materials are constantly changing due to the change in the tube diameter and the curved path, so that they collide and merge with each other to achieve full mixing. At the same time, the detection hose 8 performs a preliminary quality inspection on the mixed substance. For example, the change in tube diameter and the curved structure play a certain filtering and blocking role on the impurities in the raw materials to ensure the purity of the mixed liquid. In addition, according to different animal species and weights, the detection hose 8 of the corresponding diameter is selected, which can further adjust the flow characteristics of the mixed substance therein, thereby optimizing the mixing effect and detection accuracy to adapt to the special needs of different animals for nutrient solution. For example, for animals with smaller body size and faster metabolism, it may be necessary to select a detection hose with a smaller inner diameter to speed up the mixing speed and improve the sensitivity of detection.

[0122] The nutrient solution flows from the detection hose 8 through the discharge hole 20 into the discharge hopper 6, and then passes through the calibration flowmeter 7, which measures the outflowing nutrient solution flow again and compares it with the data of the initial flowmeter 4 to confirm the accuracy and stability of the nutrient solution flow during the entire preparation process. Subsequently, the nutrient solution flows to the three-way pipe 27. If the prepared nutrient solution needs to be tested again, the solenoid valve 1 29 can be opened and the solenoid valve 2 28 can be closed to allow the nutrient solution to return to the starting end of the device through the return pipe 31 and participate in the mixing and testing process again to ensure that the quality and uniformity of the nutrient solution reach the best state. When the nutrient solution is prepared and tested, the solenoid valve 2 28 is opened and the solenoid valve 1 29 is closed. The nutrient solution is transported to the subsequent injection equipment or storage container through the discharge pipe 30 under the action of gravity or possible pressure, ready for animal injection. 。

[0123] It is worth noting that since the viscosity of the mixed substance may be high, there is a potential impact on the blood flow and drug absorption of animals. Therefore, it is particularly important to select a detection hose 8 of a corresponding diameter according to different animal species and weights. The different inner diameters of the detection hose 8 will affect the flow characteristics of the mixed substance therein, and then affect the mixing effect and detection accuracy, so as to adapt to the needs of different animals for nutrient solution.

[0124] When it is necessary to change the inner diameter of the detection hose 8, after the servo motor 3 is started, its output shaft drives the driving gear 15 to rotate, and the driving gear 15 meshes with the transmission gear 11 installed outside the feed elbow 9, thereby driving the feed elbow 9 to rotate, so that the feed assembly connected to the lower end of its straight tube rotates, and the injection pipe 13 in the feed assembly drives the annular cover 10 to slide in the limiting ring groove 17, guiding the injection pipe 13 to move, and the smooth transition part between the injection pipe 13 and the injection port 23 abuts against the edge of the feed hole 19 in the initial state, driving the injection pipe 13 to move upward until the lower end of the injection port 23 abuts against the upper end surface of the upper mounting plate 18, at this time, the first return spring 16 and the second return spring 32 are both compressed until the injection pipe 13 rotates to the required detection hose 8, the servo motor 3 stops rotating, the first return spring 16 and the second return spring 32 restore their original length, driving the injection pipe 13 to restore the initial state, at this time the injection port 23 is located in the selected detection hose 8.

[0125] The raw materials flow from the feed elbow 9 into the injection tube 13 via the fixed tube 24. The diameter design of the injection tube 13 and the fixed tube 24 provides temporary storage and buffer space for raw materials of different viscosities. The extension tube 25 is connected to the injection tube 13 and is sleeved on the outside of the fixed tube 24 to ensure that the nutrient solution flows smoothly into the injection tube 13. The first return spring 16 and the piston ring 22 work together. When the injection tube 13 may be displaced due to the pressure generated by the change in raw material viscosity or the impact of external force, the first return spring 16 buffers and maintains the connection between the injection tube 13 and the feed hole 19. The piston ring 22 prevents leakage of high-viscosity raw materials, thereby ensuring accurate delivery of raw materials.
