Description

Technical Field

[0001] This invention belongs to the field of piglet feeding technology, specifically relating to a piglet feeding device and feeding method. Background Technology

[0002] Piglet feeding is a crucial step in pig farming, and porridge feeding has become a commonly used method in recent years. Porridge feeding is widely used in actual production due to its high palatability, good digestibility and absorption, and promotion of piglet growth. However, it still suffers from problems such as low feeding efficiency, high diarrhea rates, and difficulty in manual cleaning, which further affect fattening stage pig farming and severely restrict the profitability of pig farms. Specific manifestations are as follows.

[0003] (1) The nutritional and feed intake requirements of piglets cannot be organically combined with the feeding equipment, resulting in low feeding efficiency. At present, porridge feeding equipment has been launched in the market for piglet feeding stage, but most of them rely on manual experience and mechanical feeding and watering, which cannot meet the nutritional and feed intake requirements based on the age or weight of piglets. The actual operation is not organically combined with the porridge feeding equipment, and the feeding and watering cannot be intelligently adjusted as the piglets get older. There is a lot of manual intervention in the feeding process, resulting in low management efficiency and feeding efficiency. (2) It is not possible to quickly identify pigs that eat little or no feed. Piglets in the nursery stage have low disease prevention ability. After the onset of diseases such as diarrhea, the main manifestations are reduced feed intake and reduced feeding behavior. Piglets urgently need treatment, but in actual production, most rely on manual inspection of sick pigs, which is time-consuming and laborious. It is not possible to quickly determine the feeding status of piglets, and it is easy to miss the best time to take isolation and treatment measures, resulting in slow growth of pigs, or even stunted pigs and dead pigs being culled. (3) The feed and water lack heating and heat preservation measures, and low temperature weather increases the probability of piglets getting sick. In the south, the indoor temperature in winter is around 15℃ and the drinking water temperature is as low as 5℃, which cannot reach the suitable environmental temperature and drinking water temperature for piglets. Piglets are very sensitive to temperature changes. Low temperature feed and water feeding stimulates the piglets' intestines, increasing the chance of diarrhea and other diseases, further increasing the difficulty and cost of feeding. (4) Manual cleaning of feed trays is difficult and heavy. At present, the feed trays of porridge feed equipment do not have the function of cleaning leftover feed in actual application. Especially in summer, the temperature is high and the leftover feed is prone to deterioration and bacterial growth, which seriously wastes feed and affects the health of piglets. Generally, manual cleaning with high pressure water gun is used, which wastes a lot of water and is a heavy cleaning task. (5) It is impossible to judge the weight of leftover feed, resulting in serious feed waste. The overall daily weight gain and daily feed consumption of piglets are important indicators for measuring their growth. At present, the piglet feeding equipment lacks the function of accurately judging the weight of leftover feed, and cannot change the subsequent feeding settings in time according to the specific leftover feed situation, resulting in feed waste.

[0004] Furthermore, the previously developed intelligent feeding device can convert dry feed into liquid feed / porridge, enabling smooth porridge delivery. It allows for flexible, efficient, and selective delivery of porridge to specific feeding areas frequented only by pigs. However, it is primarily designed for fattening pigs and is not suitable for piglet feeding. More importantly, it struggles to ensure successful feeding for piglets and balanced feeding among different piglets. Summary of the Invention

[0005] At least in view of the technical problems mentioned in the background art, the present invention aims to provide a piglet feeding device and feeding method.

[0006] The present invention adopts the following technical solution.

[0007] A piglet feeding device includes a feed cylinder, a feeding trough below the feed cylinder, a spiral stirring mechanism inside the feed cylinder, a stirring shaft of the spiral stirring mechanism coaxially arranged with the feed cylinder, spiral stirring blades on the stirring shaft located in the discharge channel at the bottom of the feed cylinder, a constant temperature water tank on the side of the feed cylinder, a water outlet pipe of the constant temperature water tank extending to the top of the feeding trough or inside the feeding trough, a rotating component inside the feeding trough, a drive motor of the rotating component located at the bottom of the feeding trough, the rotation center of the rotating component located in the middle of the feeding trough and arranged directly below the discharge channel, and the rotating component being able to be submerged inside the feed body after each feeding.

[0008] To better ensure that piglets can eat smoothly and that different piglets can eat in a balanced way, the rotating component includes a vertical shaft with a conical surface at the top and a horizontal connecting rod at the bottom. One of the walls of the horizontal connecting rod is a vertical surface, and the wall opposite the vertical surface on the horizontal connecting rod is an inclined surface. The bottom of the horizontal connecting rod is a rubber component, and the upper part of the horizontal connecting rod has multiple protrusions arranged at intervals.

[0009] To make it easier for piglets to eat, the root of the transverse connecting rod is thicker than the tip; all the protrusions are arranged in a curved structure.

[0010] To reduce the difficulty of cleaning the feeding trough and improve cleaning efficiency, a strip-shaped through hole is radially provided on the bottom wall of the feeding trough. A baffle that can block the strip-shaped through hole is fitted inside the through hole. The first leaf of the hinge is used as the baffle, and the second leaf of the hinge is fixed to the bottom surface of the feeding trough. The first leaf of the hinge is connected to an electric push rod. When the electric push rod is extended, the first leaf just blocks the strip-shaped through hole. When the electric push rod is retracted, the first leaf moves away from the strip-shaped through hole, and the strip-shaped through hole is opened.

[0011] Furthermore: a weighing sensor is installed on the bottom of the feed trough, a temperature sensor and a liquid level sensor are installed inside the feed trough, and a pig identification element is installed above the feed trough; the weighing sensor, temperature sensor, liquid level sensor, pig identification element, spiral stirring mechanism, drive motor of rotating parts, electric push rod, and constant temperature water tank are all connected to the control system.

[0012] A feeding method using the aforementioned piglet feeding equipment, wherein the control system's storage module stores a program that can run on the processor module, and the processor module executes the program to perform at least the following steps:

[0013] S1, During the feeding period, when the piglets approach the feed trough and stay for a preset time, the piglets' identity information is identified and matched with their age information;

[0014] S2, control the electric push rod to extend so that the first leaf just blocks the strip-shaped through hole;

[0015] S3, Match the corresponding feed and water amounts on the feeding model according to the age information, and then control the spiral stirring mechanism and constant temperature water tank to operate according to the feed and water amounts until the feed and water amounts in the trough meet the requirements.

[0016] S4 controls the operation of the drive motor of the rotating component, so that the rotating component runs according to the set mode one until some of the food is close to the edge of the inner cavity of the feeding trough and then stops; the set mode one includes repeated and intermittent operation in the manner of "rotating component running forward for T1 minutes - rotating component running in reverse for T2 minutes";

[0017] S5, after the piglets finish eating, control the electric push rod to retract, so that the strip-shaped through hole is opened, and then continue to control the drive motor of the rotating part to run according to the set mode two until the weight of the feed trough reaches the initial value and stops.

[0018] Furthermore, it also includes step S21:

[0019] Before executing step S3, the constant temperature water tank is pre-controlled to operate, and a preset amount of water is placed into the feeding trough. Then, the drive motor of the rotating component is controlled to operate, so that the rotating component rotates for a set time T3 minutes. Then, the electric push rod is controlled to retract, so that the strip-shaped through hole is opened and the preset amount of water is discharged. Finally, the electric push rod is controlled to extend, so that the first leaf block the strip-shaped through hole.

[0020] As a preferred option, when piglets are 21 to 40 days old, the amount of feed given at one time should be controlled at 300 to 400g, the feeding interval should be controlled at 5.5 to 6.0 minutes, 4 to 6 feeding time periods should be set every day, and the feed-to-water ratio should be set at 1:3.5 to 1:5.

[0021] To minimize the waste of feed in the trough by piglets, step S41 is also included: During the feeding process, when the top surface of the feed is not lower than 1 / 3 of the maximum height of the transverse connecting rod, the rotating component is always controlled to run forward at a set speed V1, with the set speed V1 controlled at 5-10 revolutions / minute; when the top surface of the feed is lower than 1 / 3 of the maximum height of the transverse connecting rod, the rotating component is always controlled to run in the reverse direction at a set speed V2, with the set speed V2 controlled at 2-4 revolutions / minute.

[0022] Beneficial Effects: This invention incorporates a feed intake model based on piglet age changes, automatically adjusting daily feed and water intake according to piglet age. It facilitates remote data collection, display, and setting, reducing manual labor. The invention can identify pre-feed water heating, post-feed feed warming, and whether piglets are eating and the duration of feeding, helping to reduce the impact of low temperatures, especially in winter, on piglet health. It allows for timely identification of pigs that are eating little or not at all, enabling appropriate measures to be taken to reduce the likelihood of disease. The invention also features leftover feed weighing and feed tray cleaning functions. Real-time weighing of leftover feed in the tray provides a strategy for the next feeding time, facilitating the implementation of "more leftovers, less feed; less leftovers, no feed; no leftovers, more feed," reducing feed waste while meeting the growth requirements of pigs. Cleaning leftover feed in the trough ensures fresh piglet feed and reduces the risk of disease. This invention employs a rotating component with the aforementioned specific structure and feeding method, making it particularly suitable for feeding piglets. More importantly, it ensures that piglets can eat smoothly and that different piglets can eat evenly. During use, after the feed and water are added from the feed hopper and fall into the feeding trough, the rotating component enables the feed and water to mix thoroughly and accumulate along the transverse connecting rod towards the inner edge of the feeding trough. The feed in the inner edge of the entire feeding trough is also more uniform, making it easier for piglets to eat smoothly. When the feed in the feeding trough is lower than 1 / 3 of the maximum height of the transverse connecting rod, the rotating component is always controlled to run in the opposite direction at a set speed V2, which ensures that the remaining feed continues to accumulate, making it easier for piglets that are still eating to eat, while also helping to avoid feed waste.

[0027] The technical solutions of this invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention. Example

[0028] A piglet feeding device includes a feed cylinder 1, a feeding trough 2 below the feed cylinder 1, a spiral stirring mechanism inside the feed cylinder 1, the stirring shaft of the spiral stirring mechanism being coaxially arranged with the feed cylinder 1, the spiral stirring blades on the stirring shaft being located in the discharge channel 5 at the bottom of the feed cylinder 1, a constant temperature water tank 11 being arranged on the side of the feed cylinder 1, the water outlet pipe of the constant temperature water tank 11 extending to the top of the feeding trough 2 or inside the feeding trough 2, a rotating component being arranged inside the feeding trough 2, the drive motor of the rotating component being located at the bottom of the feeding trough 2, the rotation center of the rotating component being located in the middle of the feeding trough 2 and arranged directly below the discharge channel 5, and the rotating component being able to be submerged inside the feed body after each feeding.

[0029] In this embodiment, the rotating component includes a vertical shaft 21 with a tapered surface at its top. A transverse connecting rod 22 is located at the bottom of the vertical shaft 21. One wall of the transverse connecting rod 22 is a vertical surface 23, and the wall of the transverse connecting rod 22 opposite to the vertical surface 23 is an inclined surface 24. The bottom of the transverse connecting rod 22 is a rubber component, and the upper part of the transverse connecting rod 22 has multiple protrusions 25 arranged at intervals. The protrusions 25 are made of silicone. The root of the transverse connecting rod 22 is thicker than the tip of the transverse connecting rod 22; all the protrusions 25 are arranged in a curved structure.

[0030] In this embodiment, a strip-shaped through hole 6 is radially provided on the bottom wall of the feeding trough 2. A baffle capable of blocking the strip-shaped through hole 6 is fitted inside the strip-shaped through hole 6. The first leaf 9 of the hinge 7 is used as the baffle, and the second leaf of the hinge 7 is fixed to the bottom surface of the feeding trough 2. The first leaf 9 of the hinge 7 is connected to the electric push rod 8. When the electric push rod 8 extends, the first leaf 9 just blocks the strip-shaped through hole 6. When the electric push rod 8 retracts, the first leaf 9 moves away from the strip-shaped through hole 6, and the strip-shaped through hole 6 is opened.

[0031] In this embodiment, a weighing sensor 10 is installed on the bottom surface of the feeding trough 2, and a temperature sensor and a liquid level sensor are installed inside the feeding trough 2. A pig identification element is installed above the feeding trough 2. The weighing sensor 10, temperature sensor, liquid level sensor, pig identification element, spiral stirring mechanism, drive motor of rotating component, electric push rod 8, and constant temperature water tank 11 are all connected to the control system. The temperature sensor and liquid level sensor are installed at the lower end of the telescopic rod of the telescopic device 12 to facilitate flexible adjustment of the monitoring height of the temperature sensor and liquid level sensor, which is suitable for pigs of different ages.

[0032] A feeding method using the piglet feeding equipment in this embodiment, wherein the storage module of the control system stores a program that can run on the processor module, and the processing module executes the program to perform at least the following steps:

[0033] S1, During the feeding period, when the piglet approaches the feed trough 2 and stays for a preset time, the piglet's identity information is identified and matched with the piglet's age information;

[0034] S2, control the electric push rod 8 to extend so that the first leaf 9 just blocks the strip-shaped through hole 6;

[0035] Step S21: Before executing step S3, the constant temperature water tank 11 is pre-controlled to run, and the preset amount of water is put into the feeding trough 2. Then, the drive motor of the rotating component is controlled to run, so that the rotating component rotates for a set time T3 minutes. Then, the electric push rod 8 is controlled to retract, so that the strip-shaped through hole 6 is opened and the preset amount of water is discharged. Finally, the electric push rod 8 is controlled to extend, so that the first leaf 9 blocks the strip-shaped through hole 6.

[0036] S3, Match the corresponding feed amount and water amount on the feeding model according to the age information, and then control the spiral stirring mechanism and constant temperature water tank 11 to operate according to the feed amount and water amount until the feed amount and water amount in the feeding trough 2 meet the feeding requirements.

[0037] The general principles of the feeding model are as follows: When piglets are 21-40 days old, the single feed intake should be controlled at 300-400g, the feeding interval at 5.5-6.0min, and 4-6 feeding periods per day should be set, with a feed-to-water ratio of 1:3.5-1:5. The specific linear relationship (data) of this model should be set by those skilled in the art based on the piglet breed. Taking a three-way crossbred pig as an example, the feeding model is y=27.5x-452, R... 2 =0.9945, where x represents age in days, ranging from 21 to 40 days, and y represents daily feed intake in grams. When x = 40 days, y = 648 g.

[0038] S4 controls the drive motor of the rotating component to run, so that the rotating component runs according to the set mode one until some of the food is close to the edge of the inner cavity of the feeding trough 2 and then stops; the set mode one includes repeated and intermittent operation in the manner of "rotating component running forward for T1 minutes - rotating component running in reverse for T2 minutes";

[0039] In this invention, the forward operation of the rotating component refers to the transverse connecting rod 22 operating in the forward direction, such as... Figure 4 In the state shown, clockwise rotation and reverse rotation of the rotating parts refer to the transverse connecting rod 22 rotating in the same direction. Figure 4 Rotate counterclockwise as shown in the diagram;

[0040] Step S41: During piglet feeding, when the top surface of the feed is not lower than 1 / 3 of the maximum height of the transverse connecting rod 22, the rotating component is always controlled to run forward at a set speed V1, which is controlled at 5-10 revolutions / minute; when the top surface of the feed is lower than 1 / 3 of the maximum height of the transverse connecting rod 22, the rotating component is always controlled to run in the reverse direction at a set speed V2, which is controlled at 2-4 revolutions / minute; where the maximum height of the transverse connecting rod 22 refers to the height of the thickest part of the transverse connecting rod 22.

[0041] S5, after the piglets finish eating, control the electric push rod 8 to retract, so that the strip-shaped through hole 6 is opened, and then continue to control the drive motor of the rotating part to run according to the set mode two until the weight of the feed trough 2 reaches the initial value and stops.

[0042] During use, when the rotating component is running in the forward direction, the feed will be fully stirred under the action of the transverse connecting rod 22. At the same time, the feed will roll over the transverse connecting rod 22 along the inclined surface 24 and move from the root (thicker part) of the transverse connecting rod 22 to the tip (thinner part), thereby realizing the circumferential rolling, radial outward movement and accumulation of the feed on the edge of the inner cavity of the feeding trough 2. When the rotating component is running in the reverse direction, the feed will be scraped by the vertical surface 23 of the transverse connecting rod 22, thereby realizing the circumferential accumulation of the feed.
