Sow is the main production factor of centralized cultivation. The lactation period of the sow is the main production process of the farm, and the feeding capacity and the feeding level of the sow directly influence not only the self health of the sow, but also the growth of the lactating piglet. The feeding parameters of the lactating sow are obtained, and the feeding process is scientifically optimized, so that the economic output of the lactating sow can be effectively improved, and the economic value of the lactating sow can be fully exerted.
In the centralized pig farm, the environment is relatively complex, and the alkaline environment caused by high temperature, high humidity and ammonia gas discharge makes most of detection instruments and equipment difficult to directly use, or the service life is extremely obviously reduced. The intelligent feeding of lactating sows is difficult to realize, and no reliable solution with controllable cost exists at present.
Moreover, due to recent production, lactating sows are relatively weak in early physical stamina, mental state and appetite, poor in intestinal digestion, and deficient in feeding regularity. Generally, porridge materials are generally adopted for feeding sows in lactation. The porridge material is easy to feed, can improve the appetite of the lactating sows, can reduce the digestion burden of the intestinal tracts on food, and can improve the nutrient absorption of the sows. However, in centralized artificial breeding or artificial auxiliary breeding (partly automatic or semi-automatic equipment intervention), due to limited personnel configuration, it is common practice to prepare a sufficient amount of porridge (dry ingredients mixed with water) and place it in a porridge tank at a time. This amount of porridge material makes it common for sows to take multiple meals over a longer period of time before the meal is completed. The problems include at least: 1. the porridge material is spoiled and deteriorated under high temperature (especially summer) environment; 2. if the hot meal is fed, the long-term placement may lead to heat loss; 3. the feeding process of the sow cannot be known; 4. the porridge materials placed for a long time can cause the phenomenon of water separation, and the sow can have a further negative effect on appetite.

Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the actual sow feeding process, the early body physical stamina, mental state and appetite of the lactating sow are relatively weak, intestinal digestion capacity is weakened, and feeding regularity is insufficient due to recent production. Generally, porridge materials are generally adopted for feeding in the lactation period of sows. The porridge material is easy to feed, can improve the appetite of the lactating sows, can reduce the digestion burden of the intestinal tracts on food, and can improve the nutrient absorption of the sows. However, in centralized artificial breeding or artificial auxiliary breeding (partly automatic or semi-automatic equipment intervention), due to limited personnel configuration, it is common practice to prepare a sufficient amount of porridge (dry ingredients mixed with water) and place it in a porridge tank at a time. This amount of porridge material makes it common for sows to take multiple meals over a longer period of time before the meal is completed. The problems include at least: 1. the porridge material is spoiled and deteriorated under high temperature (especially summer) environment; 2. if the hot meal is fed, the long-term placement may lead to heat loss; 3. the feeding process of the sow cannot be known; 4. the porridge materials placed for a long time can cause the phenomenon of water separation, and the sow can have a further negative effect on appetite. Aiming at the problems existing in the sow feeding process, the application provides the intelligent feeder for the lactating sows, which acquires the feeding condition of the sows by collecting vibration signals generated by feeding of the sows and the material level height information of the materials in the trough 4 through the material level detection assembly, and sends a blanking signal to control the blanking module 3 to perform timing blanking by adopting a preset first control logic aiming at the feeding condition of the sows, so that the timing and quantitative accurate feeding according to the feeding condition of the sows can be realized, and the intelligent feeding of the lactating sows is realized. In order that the above-recited objects, features and advantages of the present application will become more readily apparent, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description.
Example 1:
referring to fig. 1 to 3, the embodiment provides an intelligent feeder for lactating sows, which is applied to a sow obstetric table 1. The intelligent feeder specifically includes: the material level detection assembly 2, the blanking control assembly, the vibration sensor, the material trough 4 and the material bin 5;
the blanking control assembly comprises a blanking module 3 and a control module 6;
the material level detection assembly 2 is fixed above the material tank 4, keeps a preset gap height with the material tank 4 and is used for collecting material level height information of materials in the material tank 4; the height of the preset gap is 6-12cm.
The vibration sensor is arranged on the metal pipe wall of the material level detection assembly 2 and is used for continuously collecting vibration signals generated when sows eat;
the control module 6 is respectively and electrically connected with the blanking module 3, the material level detection assembly 2 and the vibration sensor, and is used for acquiring material level height information and vibration signals, determining the appetite rule of the sow for feeding according to the material level height information and the vibration signals, and sending a blanking control signal to the blanking module 3 according to the first control logic;
the control module 6 also analyzes vibration intensity, vibration frequency, vibration starting time and vibration ending time of the vibration signals according to the vibration signals acquired by the vibration sensors, draws a vibration curve graph, and adjusts a feeding curve according to the vibration curve graph;
the blanking module 3 is arranged at the bottom of the feed bin 5 and is used for receiving a blanking control signal, quantitatively blanking materials in the feed bin 5 into the feed trough 4 according to parts at regular time, and fixing the parts of each part of materials.
Specifically, referring to fig. 4, the level detecting assembly 2 provided in this embodiment includes a metal tube 21, a metal probe movably connected to the lower end of the metal tube 21, and a current detecting module; the metal probe can be turned over along the lower end of the metal tube 21, and the distance between the lower end of the metal probe and the lower end of the metal tube 21 is a first preset height. Typically, the first preset height is 5-10cm, this height is the level of 3 parts of material in the trough 4, wherein one part of material contains about 150g of feed, and the water to material ratio of the material is 2.5:1.
Wherein, metal pipe 21 is fixed in silo 4 top, and the lower extreme of metal pipe 21 forms sealed cavity through sealed inside metal pipe 21 to improve the whole adaptability to the environment of material level detection assembly, avoid the bottom material to get into the inside of metal pipe 21, cause the corruption to the metal pipe.
The current detection module is arranged in the sealed cavity. The metal probe and the trough 4 keep a preset gap height; the current detection module is respectively and electrically connected with the control module 6 and the metal probe.
In addition, the vibration sensor may be disposed in a sealed cavity inside the metal tube 21 to improve the service life of the vibration sensor.
The bottom of the trough 4 is grounded, and when the material level of the material in the trough 4 is higher than the preset gap height, the material contacts with the metal probe to form a material level detection circuit; the current detection module is used for acquiring the material level information of the materials in the trough 4 by detecting the current signal in the material level height detection circuit.
Specifically, in this embodiment, when the lower end of the metal tube 21 is sealed, the lower end of the metal tube 21 is set to be in a watertight sealed state by adopting a watertight manner, so that the wet feed can be prevented from entering the pipeline in the sealed state, and the problem of mildew and deterioration caused further can be avoided.
In a specific practical process, the metal probe adopts the conductor hanging ring 22, and the conductor hanging ring 22 is movably connected to the lower end of the metal tube 21 to form the electrode probe. When the metal tube 21 is installed, a certain gap is kept between the conductor lifting ring 22 and the trough 4, and the gap height (namely, a preset gap height) is the threshold height of the material in the trough 4, so that the relation between the amount of the material in the trough 4 and the threshold value is reflected. In the actual use process, when the material in the material tank 4 contacts with the electrode probe, the material level detection circuit can be conducted, the current detection module detects that the current value in the circuit changes, and when the control module 6 obtains that the current value in the circuit changes, the material level height of the material in the material tank 4 reaches the preset threshold height at the moment, and then the material quantity in the material tank 4 is correspondingly obtained according to the threshold height.
Wherein the height of the bottom of the conductor lifting ring 22 from the bottom of the metal tube 21 is 5-10cm. When an external force touches the conductor lifting ring 22, the conductor lifting ring 22 can turn over and lift the bottom of the conductor lifting ring 22, so that the distance from the bottom of the conductor lifting ring 22 to the bottom of the trough 4 is increased, and the distance can be increased to 6-12cm at most. In the actual raising process, materials exist at the bottom of the conductor lifting ring 22, if the bottom of the conductor lifting ring 22 cannot move, pigs cannot eat feed under the conductor lifting ring due to shielding of the conductor lifting ring 22, and accumulated materials at the bottom of the conductor lifting ring 22 can be caused, so that the accumulated materials can be moldy and spoiled. The movable gap of 6-12cm is adopted, so that most sows can directly eat through the swine nose arch opening conductor hanging ring 22, and the phenomenon that materials are stored in the trough 4 below the conductor hanging ring 22 and are spoiled and deteriorated in a high-temperature (especially summer) environment is avoided.
Specifically, the vibration sensor in this embodiment is used to capture and acquire the vibration of the metal tube 21, and the vibration range (intensity and frequency range) captured specifically is the rotation and shake of the conductor suspension ring 22 at the end of the metal tube 21. And the vibration sensor is preferably fixedly attached to the inner wall of the metal tube 21.
Further, by integrating the hardware devices in the above embodiments, the following technical effects may be achieved in the present application: when the mixed material exists in the trough 4, the conductor hanging ring 22 can vibrate or shake along with the shaking generated by feeding action when the sow feeds in the trough 4, or the feeding sow can touch the hanging ring to shake.
