Description

Technical Field

[0001] This invention relates to the field of chicken farming and feeding technology, and in particular to a method, device and storage medium for chicken feeding linkage control. Background Technology

[0002] In large-scale poultry farming, maintaining flock health and feed utilization is crucial for ensuring economic benefits. However, the disposal of leftover feed in the troughs remains a persistent technical challenge in actual production.

[0003] Current methods for handling leftover feed mostly involve mixing it evenly with new feed. While this reduces the retention time of leftover feed compared to adding new feed where it sits at the bottom, the even mixing means that some leftover feed remains at the bottom or in other hard-to-reach locations, resulting in a prolonged retention time and a high probability of spoilage and mold growth. This can negatively impact the normal development of chickens and lead to economic losses. Some existing technologies use additives to inhibit mold growth, but these additives increase feed costs and may also negatively affect the normal development of chickens. Summary of the Invention

[0004] The main objective of this invention is to provide a feeding linkage control method, device, and storage medium for chickens. This aims to address the problems in existing technologies where leftover feed is mixed with new feed through stirring, resulting in some leftover feed remaining at the bottom or in other hard-to-reach locations, remaining for a long time, and having a high probability of spoilage and mold growth, potentially affecting the normal development of chickens and causing economic losses. It also addresses the problem in existing methods using additives to inhibit mold growth, where the additives themselves increase feed costs and may negatively impact the normal development of chickens.

[0005] In a first aspect, to achieve the above objectives, the present invention provides a feeding linkage control method for chickens, comprising:

[0006] To obtain information on the feeding status of chickens and the amount of feed remaining in the feed trough;

[0007] When it is detected that the chicken has finished feeding once, the feed trough is adjusted to a preset angle no greater than the preset maximum angle according to the amount of feed remaining in the feed trough, so that the feed in the feed trough gathers in front of the chicken standing.

[0008] When the tilt angle of the feed trough reaches the preset maximum angle, before the next feeding of the chickens, the feed trough is kept tilted at the preset maximum angle. Fresh feed is added to the feed trough from a position near the rear of the feed trough. During the feeding process, the feed trough is simultaneously reset from the preset maximum angle to a horizontal state, so that after the reset, the remaining feed is in front of the newly added fresh feed. The execution time of the feed trough reset action is set to correspond to the execution time of the feeding action.

[0009] Optionally, multiple sets of feed remaining amount ranges in the feeding trough are preset, and the same number of preset tilt angles are set accordingly; the less feed remaining, the larger the corresponding preset tilt angle, and the preset tilt angles of each set increase in a step-like manner, with the preset tilt angle corresponding to the last set of feed remaining amount ranges being the preset maximum angle.

[0010] Optionally, the remaining amount of feed in the last group of feeding troughs is between 5% and 12% of the total amount of feed fed in this feeding.

[0011] Optionally, in the feeding step, fresh feed is added to the feeding trough at a uniform speed, and the feeding speed is linearly matched with the reset speed of the feeding trough, so that the thickness deviation of the fresh feed in the feeding trough does not exceed a preset value.

[0012] Optionally, the method further includes selecting a range of values ​​for the preset maximum angle based on the average age of the flock, wherein the range of values ​​for the preset maximum angle decreases as the average age of the flock increases.

[0013] Secondly, the present invention also provides a feeding linkage control device for chickens, including: a feed trough, a feeding status acquisition module, a remaining amount acquisition module, a feed trough angle adjustment module, and a feeding module;

[0014] The feeding status acquisition module is used to acquire the feeding status of chickens;

[0015] The remaining amount acquisition module is used to acquire the remaining amount of feed in the feeding trough;

[0016] The feed trough angle adjustment module is connected to the feed trough and is used to adjust the tilt angle of the feed trough. After a single feeding, the tilt angle of the feed trough is adjusted to a corresponding preset angle that is no greater than the preset maximum angle according to the current amount of feed remaining, so that the feed gathers in front of the chickens standing.

[0017] The feeding module is located near the rear of the feeding trough and is used to feed fresh feed into the feeding trough.

[0018] The feeding module is communicatively connected to the feeding trough angle adjustment module. The two work together to realize the synchronous execution of the feeding action and the feeding trough reset action, and the execution time of the reset action and the feeding action are set accordingly.

[0019] Optionally, the feeding status acquisition module is a photoelectric sensor, an infrared sensor, or a weight sensor, and the detection end of the feeding status acquisition module is correspondingly set on the side of the feed trough facing the chickens standing.

[0020] Optionally, the remaining quantity acquisition module is a weight sensor, and the detection end of the remaining quantity acquisition module is set inside the feeding trough.

[0021] Optionally, the feeding trough angle adjustment module includes a servo motor or an electric push rod, and the drive end of the feeding trough angle adjustment module is correspondingly connected to the feeding trough.

[0022] Thirdly, the present invention also provides a computer-readable storage medium storing a chicken feeding linkage control program, which, when executed by a processor, implements the chicken feeding linkage control method as described above.

[0023] This invention introduces fresh feed into the feed trough from the rear while maintaining a preset maximum angle. The feeding action and the trough resetting action are synchronized and their durations correspond, resulting in a layout where remaining feed is placed at the front and fresh feed at the rear after resetting. This prioritizes the consumption of leftover feed by leveraging the chickens' feeding habits, preventing long-term feed stagnation and reducing the probability of spoilage and mold growth. This ensures normal chicken development and improves economic efficiency. This invention eliminates the need for mold inhibitors, reducing feed costs and avoiding the potential negative impacts of additives on chicken development, further enhancing economic benefits. Furthermore, by monitoring the chickens' feeding status and the amount of feed remaining in the trough, the invention adjusts the trough angle to the preset maximum angle after each feeding, uniformly collecting the remaining feed forward. This method allows for the centralized collection of small amounts of leftover feed after feeding, preventing it from scattering within the troughs and reducing the likelihood of large-scale contact with environmental moisture and dust. This effectively lowers the risk of feed spoilage and mold, while also reducing feed loss, improving feed utilization, and contributing to energy conservation and emission reduction. Furthermore, the entire feeding process is automated and interconnected, eliminating the need for frequent manual adjustments to the trough angle and point-to-point feeding, significantly reducing labor intensity and meeting the application needs of large-scale, intelligent livestock and poultry farming. Detailed Implementation

[0024] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0025] In this invention, the use of terms such as "first," "second," etc., 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 that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] This invention provides a first embodiment of a feeding linkage control method for chickens. In this embodiment, the feeding linkage control method for chickens of this invention includes the following steps:

[0027] To obtain information on the feeding status of chickens and the amount of feed remaining in the feed trough;

[0028] Specifically, feeding status and the amount of feed remaining can be obtained manually or by setting up different sensors. For example, photoelectric sensors, infrared sensors, or weight sensors can be used to detect whether chickens are standing in front of the feed trough through photoelectric signals or weight changes. If so, it means the chickens may be feeding; if not, it means they are not feeding. Weight sensors can be used to obtain the amount of feed remaining by measuring the weight of the feed in the trough. The specific steps for detecting whether chickens are standing in front of the feed trough and detecting the amount of feed remaining in the trough using the above sensors are existing technologies and will not be described in detail here.

[0029] When it is detected that the chicken has finished feeding, adjust the feed trough to a preset angle no greater than the preset maximum angle according to the amount of feed remaining in the feed trough, so that the feed in the feed trough gathers in front of the chicken standing.

[0030] Understandably, chickens will feed multiple times. A preset time can be set after a chicken leaves the feed trough to indicate the end of a single feeding session. This preset time can be set as needed, for example, five minutes. The tilt angle of the feed trough is adjusted based on the remaining feed amount. The less feed remains, the greater the tilt angle, causing the feed to move forward and gather due to gravity, reducing the probability of feed sticking to hard-to-reach areas and facilitating feeding. Setting a preset maximum angle prevents the tilt angle from exceeding the feed's angle of repose, avoiding feed falling and improving the reliability of the invention. Furthermore, adjusting the feed trough's tilt angle only after the chickens have finished feeding avoids stress caused by adjusting the tilt angle while the chickens are feeding, further enhancing the reliability of the invention.

[0031] Once the feed trough reaches the preset maximum tilt angle, before the next feeding, keep the feed trough tilted at the preset maximum angle and add fresh feed into the feed trough from the position near the rear of the feed trough. During the feeding process, simultaneously reset the feed trough from the preset maximum angle to a horizontal position, so that after the reset, the remaining feed is in front of the newly added fresh feed. The execution time of the feed trough reset action is set to correspond to the execution time of the feeding action.

[0032] Specifically, when the tilt angle of the feed trough reaches the preset maximum angle, it indicates that the amount of feed remaining in the trough is relatively small. Therefore, after the chickens finish eating, feed should be added before the next feeding. During the feeding process, the feed trough is initially tilted at the preset maximum angle, with the remaining feed positioned towards the front. Fresh feed is added to the feed trough from near the rear. Due to gravity and the resistance of the remaining feed, the fresh feed moves to the rear of the remaining feed and comes into contact with it, forming a front-side arrangement of the remaining feed. Simultaneously, the feed trough is slowly returned to a horizontal position, gradually reducing the horizontal force. This prevents excessive fresh feed from increasing the horizontal force beyond the resistance of the remaining feed, thus avoiding feed falling off and improving the reliability of the invention. When the feed trough returns to a horizontal position, the feeding is essentially complete.

[0033] Understandably, chickens, based on their feeding habits, typically eat the feed at the front of the trough first. This invention, by adding fresh feed from the rear of the trough while maintaining a preset maximum angle, and controlling the feeding action and trough resetting action to be synchronized and corresponding in duration, ensures that after the trough resets, the remaining feed at the front and fresh feed at the rear are arranged in a layout that prioritizes the chickens' feeding habits, preventing leftover feed from remaining in the trough for extended periods. This reduces the probability of feed spoilage and mold growth due to prolonged retention, ensuring normal chicken development and improving the economic efficiency of poultry farming. This invention eliminates the need for additives to inhibit mold, reducing feed costs and avoiding the potential negative impact of additives on chicken development, further improving the economic benefits of poultry farming. Furthermore, by monitoring the chickens' feeding status and the amount of feed remaining in the trough, this invention adjusts the trough angle back to the preset maximum angle after each feeding, uniformly collecting the remaining feed at the front. This method allows for the centralized collection of small amounts of leftover feed after feeding, preventing it from scattering within the troughs and reducing the likelihood of large-scale contact with environmental moisture and dust. This effectively lowers the risk of feed spoilage and mold, while also reducing feed loss, improving feed utilization, and contributing to energy conservation and emission reduction. Furthermore, the entire feeding process is automated and interconnected, eliminating the need for frequent manual adjustments to the trough angle and point-to-point feeding, significantly reducing labor intensity and meeting the application needs of large-scale, intelligent livestock and poultry farming.

[0034] The multiple technical features of this invention support each other functionally, together producing the overall effect of leftover feed on the front and fresh feed on the back, guiding chickens to naturally prioritize the consumption of leftover feed. This overcomes the limitations of existing technologies that only solve the problem of leftover feed retention by stirring and mixing feed and adding anti-mold agents.

[0035] In one embodiment, multiple sets of feed remaining amount ranges in the feed trough are preset, and the same number of preset tilt angles are set accordingly; the less feed remaining, the larger the corresponding preset tilt angle, and the preset tilt angles of each set increase in a step-like manner, with the preset tilt angle corresponding to the last set of feed remaining amount ranges being the preset maximum angle.

[0036] Understandably, when there is a large amount of feed remaining, only a small angle is needed to move and gather the remaining feed forward. Conversely, the smaller the amount of feed remaining, the larger the tilt angle required to move it forward. Therefore, this step-by-step increasing strategy avoids the drawbacks of a fixed angle, which may lead to feed spillage when there is a large amount of feed remaining or ineffective movement when there is very little feed remaining. Furthermore, compared to continuous stepless adjustment or adjusting to the maximum angle all at once, step-by-step adjustment only triggers the next angle increase when the remaining feed drops to a specific threshold. This reduces the frequency of the feed trough adjustment mechanism's operation, lowers the load on the servo motor or electric actuator, and thus extends the equipment's lifespan. Moreover, chickens are sensitive to sudden changes in the environment; the step-by-step gradual increase in tilt angle makes the change in the feed trough's posture smoother, resulting in a smaller change in the angle the chicken faces each time it returns to the feed trough, which helps reduce stress and maintain normal feeding behavior.

[0037] Furthermore, the remaining feed in the last set of feed troughs is typically 5% to 12% of the total feed fed in this feeding session. Setting the threshold for triggering the preset maximum tilt angle at 5% to 12% of the total feed is a critical window optimized based on chicken feeding behavior patterns and feed physical properties. Activating the preset maximum angle within this range effectively concentrates and pushes the thin layer of remaining feed to the front of the feed trough, placing it in a priority contact position for the chickens in the next feeding round, ensuring priority consumption of the remaining feed. This threshold range, while ensuring priority consumption of remaining feed, reduces equipment wear and feed spillage risks caused by excessive adjustment, and is an optimal range determined by those skilled in the art based on breeding experience. Moreover, when the remaining feed is below 5%, the remaining feed is usually cleaned up directly during feeding, eliminating the need to adjust the trough tilt angle again, avoiding meaningless actions, and saving energy and reducing emissions.

[0038] In one embodiment, during the feeding step, fresh feed is added to the trough at a uniform speed, with the feeding speed linearly matched to the trough's resetting speed, ensuring that the thickness deviation of the fresh feed layer in the trough does not exceed a preset value. By linearly matching the feeding speed with the trough's resetting speed, it is ensured that as the trough gradually returns to a horizontal position from its tilted state, the newly added feed is evenly distributed on the rear side of the trough, forming a stable and repeatable layered structure with remaining feed on the front and fresh feed on the rear. The thickness deviation is controlled within the preset value, avoiding uneven feed distribution caused by excessively thick or thin areas. This uniform distribution not only facilitates the natural consumption sequence of fresh and remaining feed during chicken feeding but also reduces feed waste and the risk of mold growth caused by localized accumulation. Simultaneously, the speed matching control synchronizes the end of feeding with the trough's return to a horizontal position, making the entire feeding process smooth and efficient. Specifically, the preset value can be set so that the thickness deviation of the fresh feed layer in the trough does not exceed ±10%.

[0039] In one embodiment, the feeding linkage control method for chickens of the present invention further includes selecting a preset maximum angle range based on the average age of the flock, wherein the preset maximum angle range decreases as the average age of the flock increases.

[0040] Understandably, the feed form used by chickens of different ages differs significantly. Chicks typically use powdered or crushed feed, which has a large angle of repose and poor flowability, requiring a larger tilt angle to move leftover feed forward. Adult chickens, on the other hand, use pelleted feed, which has a small angle of repose and good flowability, requiring only a smaller tilt angle to move it. This solution introduces age parameters to automatically adjust the preset maximum angle range, matching the trough tilting strategy to the actual feeding characteristics of the chickens and the physical properties of the feed. This adaptive adjustment avoids the inappropriateness of a fixed angle: using too small an angle for chicks will result in ineffective collection of leftover feed, while using too large an angle for adult chickens will cause pellets to spill. Therefore, it achieves optimal collection of leftover feed at different growth stages, improving the practicality and intelligence of the solution.

[0041] Furthermore, image recognition and spectral recognition can be linked to identify the morphological composition of the feed, accurately determining the proportion of powder and pellets to calculate the preset maximum angle range. Specifically, an image acquisition device (such as a CCD industrial camera) and a spectral sensor (such as a near-infrared spectrometer) are installed at the feed inlet of the feeding module or above the feed trough. Before or during each feeding, the system automatically acquires images and spectral data of the feed sample.

[0042] The image acquisition device obtains the particle size distribution of the feed pellets. An image segmentation algorithm identifies pellets larger than a first threshold (e.g., 2 mm) and powders smaller than a second threshold (e.g., 0.5 mm), calculating their respective pixel area ratios or particle count ratios. A spectral sensor acquires the reflectance spectrum of the feed in a specific wavelength range (e.g., 950-1650 nm). Using a pre-established partial least squares (PLS) or neural network model, it predicts the protein, starch, and moisture content of the feed, as well as the overall powder / particle ratio. The central controller weightedly fuses the particle morphology ratios obtained from image recognition with the component ratios obtained from spectral analysis to obtain the final powder and pellet ratios.

[0043] The preset maximum angle is determined based on the ratio of powder to pelleted feed. Specifically, the preset maximum angle varies linearly between the minimum preset angle and the maximum allowable angle; for example, the minimum preset angle can be set to 8°, and the maximum allowable angle can be set to 20°. When the powder content is higher, the preset maximum angle is closer to the maximum allowable angle to ensure that powdered feed with a large angle of repose can slide forward smoothly under gravity; when the pelleted feed content is higher, the preset maximum angle is closer to the minimum preset angle to prevent pelleted feed from rolling off the front of the trough due to excessive tilt angle, resulting in feed waste.

[0044] This embodiment enables real-time adjustment of the preset maximum angle range based on the morphological composition of different batches of feed, eliminating the need for manual calibration or experience-based settings, thus significantly improving the practicality and intelligence of the invention.

[0045] Based on the same inventive concept, this invention also proposes a feeding linkage control device for chickens, including: a feed trough, a feeding status acquisition module, a remaining feed acquisition module, a feed trough angle adjustment module, and a feeding module; the feeding status acquisition module is used to acquire the feeding status of the chickens; the remaining feed acquisition module is used to acquire the remaining amount of feed in the feed trough; the feed trough angle adjustment module is connected to the feed trough and is used to adjust the tilt angle of the feed trough so that after a single feeding, the tilt angle of the feed trough is adjusted to a corresponding preset angle not greater than the preset maximum angle according to the current remaining feed, so that the feed gathers towards the front side where the chickens are standing; the feeding module is located near the rear side of the feed trough and is used to feed fresh feed into the feed trough; the feeding module and the feed trough angle adjustment module are communicatively connected, and the two cooperate to realize the synchronous execution of the feeding action and the feed trough reset action, and the execution time of the reset action and the feeding action are set accordingly.

[0046] The technical solution of this embodiment, through the cooperation of various modules, enables the feed trough to be reset, forming a layout where the remaining feed is placed at the front and the fresh feed at the back. Based on the chickens' feeding habits, this prioritizes the consumption of leftover feed, avoiding the problem of leftover feed remaining in the feed trough for extended periods. This reduces the probability of feed spoilage and mold due to prolonged retention, ensuring the normal development of the chickens and improving the economic benefits of farming. This invention eliminates the need for additives to inhibit mold, reducing feed costs and avoiding the negative impact of additives on the normal development of chickens, further improving the economic benefits of farming. Furthermore, by acquiring the chickens' feeding status and the amount of feed remaining in the feed trough, this invention adjusts the feed trough's tilt angle to a preset maximum angle after each feeding, uniformly collecting the remaining feed forward. This method can centrally collect small amounts of leftover feed after feeding, preventing it from scattering within the feed trough and reducing the probability of large-scale contact with environmental moisture and dust, effectively reducing the risk of feed spoilage and mold. It also reduces feed loss, improves feed utilization, and is more energy-efficient and emission-reducing. In addition, the entire feeding process is automated and linked, eliminating the need for frequent manual adjustments to the feed trough angle and fixed-point feeding, which greatly reduces the intensity of manual labor and meets the application needs of large-scale and intelligent livestock and poultry farming.

[0047] In one embodiment, the feeding status acquisition module is a photoelectric sensor, an infrared sensor, or a weight sensor, with the detection end of the module positioned on the side of the feed trough facing the chickens. The photoelectric sensor, infrared sensor, or weight sensor can detect whether there are chickens in front of the feed trough. If chickens are present, it can be determined that the chickens are feeding; if they are not present, it can be determined that they are not feeding. This achieves the acquisition of the feeding status, and the structure is simple, reasonable, and highly practical.

[0048] In one embodiment, the remaining feed acquisition module is a weight sensor, and the detection end of the remaining feed acquisition module is located inside the feeding trough. The weight sensor enables the detection of the remaining feed in the feeding trough, and calculating the remaining feed by weight provides higher accuracy compared to other methods.

[0049] In one embodiment, the feeding trough angle adjustment module includes a servo motor or an electric actuator, with the drive end of the module correspondingly connected to the feeding trough. The feeding module is communicatively connected to the servo motor or electric actuator, enabling the servo motor or electric actuator to drive the feeding trough angle adjustment while feeding, ensuring the even distribution of newly added material and improving the reliability of the invention.
