Abstract
Description
Technical Field
[0001] This invention relates to the field of aquaculture technology, and in particular to an energy-nitrogen ratio control system for monitoring the production of body fat in lactating buffalo. Background Technology
[0002] Energy-nitrogen balance refers to the appropriate ratio between energy, protein, and amino acids in feed. An improper ratio can affect nutrient utilization efficiency and lead to nutritional disorders. An excessively high energy-nitrogen ratio results in decreased amino acid utilization, reduced muscle mass, and increased body fat deposition. Conversely, an excessively low energy-nitrogen ratio means that the energy intake cannot meet the animal's needs for maintenance, growth, and production. Consequently, ingested protein undergoes deamination metabolism for energy, increasing ammonia excretion, reducing ammonia utilization, wasting protein, and increasing environmental pollution. Therefore, protein supply levels should not be excessively increased or decreased, nor should protein nutrition be overemphasized when energy is insufficient. Maintaining a balanced ratio between energy and protein is extremely important for feeding lactating buffalo.
[0003] Compared to traditional weight scales, body fat scales can detect fat primarily by measuring the difference in electrical conductivity between muscle and fat. Since muscle contains a certain amount of water and is conductive, while fat is not, current passes more easily through muscle. This allows the scale to determine the proportion of muscle in body weight, and consequently, the amount of fat.
[0004] In the existing technology, there is no effective body fat monitoring facility for lactating buffalo. Therefore, based on the working principle of human body fat scales, we can set up a special body fat scale for lactating buffalo to monitor the body fat production of lactating buffalo in real time, thereby controlling the intake of energy, protein, and amino acids when feeding lactating buffalo. Furthermore, the body fat monitoring process of lactating buffalo is automated and streamlined, increasing measurement efficiency. Therefore, this application discloses an energy-nitrogen ratio control system for monitoring the body fat production of lactating buffalo to make the body fat monitoring of lactating buffalo more intuitive.

A measuring component is fixedly installed at the bottom end of the vertical moving block. The measuring component includes a fixed rod, and two collars are sleeved on the outer surface of the fixed rod. A first moving plate is rotatably installed on both sides of the two collars. A second moving plate is fixedly installed at the other end of each of the two first moving plates. Two electrode plates are disposed at the bottom end of each of the two second moving plates.

[0007] Preferably, the upper surface of the weighing platform is provided with a plurality of protruding strips arranged at equal intervals, the weighing platform is made of conductive metal, and a pressure sensor is provided inside the weighing platform.
[0008] Preferably, springs are sleeved on both sides of the fixing rod, and the two springs are respectively disposed on one side of the two collars.
[0009] Preferably, a set of clamping plates is provided on both sides of the bottom end of the measuring component.

The two sets of clamping plates are respectively fitted onto the outer surface of the two first movable plates, and the side of the clamping plate closest to the bottom surface of the first movable plate is sloped.
[0010] Preferably, the first movable plate is arranged in a straight shape, the second movable plate is arranged in an arc shape, and the two first movable plates and the two second movable plates are arranged in an inverted "V" shape.

[0016] The beneficial effects of this invention are:
[0017] 1. This energy-nitrogen ratio control system for monitoring body fat production in lactating buffalo utilizes a weighing component and a measuring component. During its movement, the buffalo passes the weighing component in the middle of the testing shed. The weighing component and the weighing platform at its base are a certain distance apart, allowing the buffalo sufficient time to walk on the platform and remain there for a certain period. This ensures the buffalo is fully weighed while walking, accurately recording its weight data, which is displayed on a screen. Simultaneously, while the buffalo is on the weighing platform, the measuring component is positioned between its neck and back, with electrodes connected to the buffalo's skin. As the buffalo continues to walk, the measuring component and a vertical moving block move along a slide rail, ensuring timely measurement. Meanwhile, motors on two secondary moving plates conduct electricity, one positive and one negative. An impedance meter connected to the electrodes measures and analyzes the buffalo's body fat. The analyzed data is also displayed on the screen, providing a direct comparison with the weight data.
[0018] 2. This energy-to-nitrogen ratio control system for monitoring the production of body fat in lactating buffalo utilizes a push plate and connecting rod within the measurement assembly. Through the coordinated action of the connecting rod, push plate, first moving plate, and second moving plate, it ensures that the electrode pads and vertical moving blocks are not squeezed or dislodged during the buffalo's undulating movement, thus improving the accuracy and stability of the measurement. It also ensures that the electrode pads remain in the appropriate position throughout the measurement process, while preventing excessive force on the electrode pads during the buffalo's undulating movements. The coordinated sliding motion keeps them in the correct position, ensuring the reliability of the measurement.
[0019] 3. This energy-nitrogen ratio control system for monitoring the production of body fat in lactating buffalo uses a telescopic rod connected to a connecting rod below a longitudinal moving block on a positioning component. A return spring is fitted to the telescopic end of the telescopic rod. After the vertical moving block rises to separate the measuring component from the buffalo, the return spring forces the longitudinal moving block to quickly return it to the fixed position, allowing for testing of the next buffalo, thus achieving streamlined measurement of buffalo fat.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0034] like Figures 1 to 9As shown, a control system for monitoring the energy-to-nitrogen ratio of body fat production in lactating buffalo includes: a detection shed 1, with pads 4 at both ends of the detection shed 1, and a hollow bottom plate; a weighing assembly 5, which is fixedly installed in the center of the detection shed 1, with several fixed legs 6 at the bottom of the weighing assembly 5 and fixedly installed inside the bottom plate of the detection shed 1, the weighing assembly 5 including a weighing platform 7 and fences 8 on both sides of the weighing platform 7; and a positioning assembly 9, which is fixedly installed at the top of the two fences 8, with slide rails 10 on both sides of the upper end of the positioning assembly 9, a distance sensor 29 at one end of each slide rail 10, and a longitudinal moving block 11 sliding on the slide rail 10. A transverse moving block 12 is slidably disposed on one side of the longitudinal moving block 11, and a vertical moving block 14 is slidably disposed on the other side of the transverse moving block 12. A first servo motor 13 for driving the transverse moving block 12 and a second servo motor 15 for driving the vertical moving block 14 are respectively disposed on both sides of the transverse moving block 12. A measuring component 16 is fixedly installed at the bottom end of the vertical moving block 14. The measuring component 16 includes a fixed rod 17. Two collars 18 are sleeved on the outer surface of the fixed rod 17. A first moving plate 19 is rotatably installed on both sides of the two collars 18. A second moving plate 20 is fixedly installed at the other end of each of the two first moving plates 19. Two electrode plates 21 are disposed at the bottom end of each of the two second moving plates 20.An impedance meter 30 is fixedly installed at one end of the exterior of the testing shed 1. A display screen 31 is mounted on the top of the impedance meter 30. The impedance meter 30 is electrically connected to the electrode plate 21. Several equidistant protrusions are arranged on the upper surface of the weighing platform 7. The weighing platform 7 is made of conductive metal and contains a pressure sensor. The first moving plate 19 is straight, and the second moving plate 20 is arc-shaped. The two first moving plates 19 and two second moving plates 20 together form an inverted "V" shape. The impedance meter 30 contains a data storage module. When measuring the body fat of a cow, the cow is driven to one side of the testing shed 1. It first enters the testing shed 1 through the pad 4 on one side of the testing shed 1, and then... The cow continues walking forward in the testing shed 1. During its journey, the cow passes the weighing component 5 in the middle of the shed. The weighing component 5 and the weighing platform 7 at its bottom are a certain distance apart, allowing the cow a sufficient walking time on the platform 7 to remain completely on it for a certain period. This ensures the cow is fully weighed while walking, accurately recording its weight data, which will be displayed on the screen 31. When the cow reaches the weighing platform 7, the pressure sensor on the platform detects pressure, activating the first servo motor 13 on the positioning component 9 to drive the lateral moving block 12 to adjust its lateral position. Meanwhile, the second servo motor 15 in the positioning component 9 drives the vertical... The measuring component 16 slides downwards onto the moving plate 14, thereby pressing it down between the cow's neck and back. The first moving plate 19 and the second moving plate 20 on the measuring component 16 are V-shaped, simulating the traction tool used when the cow is plowing. This allows the measuring component 16 to easily lock between the cow's neck and back. At the same time, the vertical moving block of the positioning component 9 is pressed down to limit its movement and prevent it from falling off. At this time, the electrode 21 is connected to the cow's skin. As the cow continues to walk forward, the measuring component 16 and the vertical moving block 14 will drive the longitudinal moving block 11 to slide on the slide rail 10, thus following the cow's movement and ensuring measurement time. Meanwhile, the motor plates distributed on the two second moving plates 20 are respectively positive and negative. The negative electrode 21 conducts electrical conductivity, and then the impedance meter 30 connected to the electrode plate 21 measures and analyzes the body fat of the cow. The analyzed data is also displayed on the display screen 31, allowing for intuitive understanding and comparison with the weight data. Simultaneously, the analyzed data can be directly stored in the data storage module for easy retrieval and comparison later. When the cow completes the body fat and weight measurement while walking, as it continues to walk forward, it causes the longitudinal moving block 11 to touch the distance sensor 29. At this time, the second servo motor 15 starts, causing the vertical moving block 14 to rise, separating the measuring component 16 from the cow. Then, it resets and repeats the operation with the next cow, thus achieving a streamlined measurement effect and improving the fat measurement results.
[0035] like Figures 2 to 6As shown, springs are respectively fitted on both sides of the fixing rod 17, and the two springs are respectively set on one side of the two collars 18. A set of clamping plates 22 is respectively set on both sides of the bottom end of the measuring component 16. Each set of clamping plates 22 consists of two plates, which are arranged opposite each other and have an "L" shaped cross-section. The two sets of clamping plates 22 are respectively fitted with the outer surface of the two first moving plates 19, and the side of the clamping plate 22 near the bottom surface of the first moving plate 19 is sloping. A connecting rod 23 is rotatably connected to the bottom of the two collars 18. A push plate 24 is rotatably connected to the bottom end of the connecting rod 23. The push plate 24 is set in an upwardly convex arc shape. When the cow walks during the fat measurement process, the cow's walking will produce an undulating effect. During the cow's undulation, the push plate 24 will move up and down, which in turn will push the two collars 18 away from each other or closer together through the connecting rod 23 above the push plate 24, thereby driving the first moving plate 19 to move closer together. The sliding plate 19 and the second sliding plate 20 slide to provide the buffalo with an undulating range during its movement. When the buffalo floats upward, the first sliding plate 19 and the second sliding plate 20 slide outward to match the buffalo's upward movement, ensuring that the buffalo does not squeeze the electrode plate 21 or the vertical moving block 14 during its upward movement. When the buffalo floats downward, the first sliding plate 19 and the second sliding plate 20 slide inward under the force of the spring to clamp the buffalo's body. It is worth noting that even though the second sliding plate 20 will cause the electrode plate 21 to move slightly during its sliding, the second sliding plate 20 remains in close contact with the buffalo's body and will not cause the electrode plate 21 to detach from the buffalo's body and interrupt the measurement. At the same time, the sliding setting of the clamping plate 22 coordinates the sliding of the first sliding plate 19 and the second sliding plate 20 during the buffalo's undulating movement, which helps to keep the electrode plate 21 in the proper position during the buffalo's movement without being squeezed or detached.
[0036] like Figure 5 , Figure 7 As shown, a connecting rod 25 is provided below the longitudinal moving block 11, and a fixed block 26 is provided on one side of the positioning component 9. A telescopic rod 27 is fixedly installed on the side of the fixed block 26 near the connecting rod 25. The telescopic end of the telescopic rod 27 is connected to the connecting rod 25, and a return spring 28 is sleeved on the telescopic end of the telescopic rod 27. When the longitudinal moving block 11 touches the distance sensor 29, the second servo motor 15 starts and drives the vertical moving block 14 to rise, so that the measuring component 16 is separated from the cow. Under the force of the return spring 28, the longitudinal moving block 11 is driven to quickly return to the position of the fixed block 26 for detection of the next cow.
[0037] like Figure 1As shown, observation windows 2 are provided on both sides of the testing shed 1. A fan 3 is installed at the top of the testing shed 1. The cross-section of the pad 4 is a right-angled triangle. One end of the pad 4 is flush with the height of the bottom plate of the testing shed 1, ensuring that the buffalo can easily enter and leave the testing shed 1. At the same time, the observation windows 2 can be used to monitor the behavior and status of the buffalo in the testing shed 1. The fan 3, together with the observation windows 2, provides ventilation, improves the air circulation in the testing shed 1, maintains a suitable temperature and humidity, and thus improves the comfort of the buffalo in the testing shed 1, helping to avoid the adverse effects of excessive heat or humidity on the health of the buffalo.
[0038] The working principle of this invention is as follows: When measuring the body fat of a cow, the cow is driven to one side of the testing shed 1. First, it enters the testing shed 1 through the pad 4 on one side. Then, the cow continues to walk forward within the testing shed 1. During its movement, the cow passes the weighing component 5 in the middle of the testing shed 1. Since there is a certain distance between the weighing component 5 and the weighing platform 7 at its bottom, the cow has a certain amount of walking time on the weighing platform 7, allowing it to remain completely on the platform for a certain period. Therefore, the cow can be fully weighed while walking, and its weight data can be accurately recorded. The cow's weight data will be displayed on screen 31. When the cow walks onto the weighing platform 7, the pressure sensor on the weighing platform 7 detects pressure, thereby activating the first servo motor 13 on the positioning component 9 to drive the lateral moving block 12 to adjust its lateral position. Meanwhile, the second servo motor 15 in the positioning component 9 drives the vertical moving plate 14 to slide downwards, thereby causing the measuring component 16 to press downwards between the cow's neck and back. The first moving plate 19 and the second moving plate 20 on the measuring component 16 are V-shaped, which can simulate the traction tool used when the cow is plowing, so that the measuring component... Measuring plate 16 can easily be positioned between the cow's neck and back, while the vertical moving block of positioning component 9 presses down to limit its movement and prevent it from falling off. At this time, electrode plate 21 is connected to the cow's skin. As the cow continues to walk forward, the measuring component 16 and the vertical moving block 14 drive the longitudinal moving block 11 to slide on the slide rail 10, thus following the cow's movement and ensuring measurement time. Meanwhile, the motor plates distributed on the two second moving plates 20 conduct electricity with one positive and one negative polarity, and then the impedance meter 30 connected to electrode plate 21 is used for measurement and analysis. The analyzed data is also... The display screen 31 shows the weight data for intuitive understanding and comparison. The analyzed data can be directly stored in the data storage module for easy retrieval and comparison later. When the cow completes the measurement of body fat and weight while walking, as it continues forward, the longitudinal moving block 11 touches the distance sensor 29. At this time, the second servo motor 15 starts, causing the vertical moving block 14 to rise, separating the measuring component 16 from the cow. Then, it resets and repeats the operation with the next cow, achieving a streamlined measurement effect and improving the fat measurement results.
