Description

Technical Field

[0001] The invention relates to the technical field of intelligent breeding, and in particular to an automatic feeding system for boar liquid feed. Background Art

[0002] Pig farms have a kind of pig house specially used for raising boars, which are divided into boar house and boar station according to their size and purpose. General boar house is mainly used to provide pig semen for artificial insemination of sows in the pig farm, commonly known as boar house. Boar station is larger in scale, used to provide pig semen for artificial insemination of sows under the group company, and even directly package and sell pig semen.

[0003] For the latter, the general breeding scale is about 300 boars. At the same time, it has the strictest biosafety level among all pig farms. Because boars are expensive, the male-female ratio in general pig farms is 1:100. The loss of one boar will result in 100 sows being unable to obtain semen. At the same time, considering the export or delivery of semen, the semen product itself needs to be of high quality and high biosafety.

[0004] High-quality semen generally comes from the feeding and conditioning of boars, which is mainly determined by feed, drinking water and environment. In terms of feed, most boar stations currently use artificial feeding or dry feed line system for feeding. Both methods have certain problems:

[0005] 1. Although artificial feeding can achieve individual feed configuration for each boar to meet individual requirements, physical fitness and weight control can be improved by adding individual nutrients, but artificial feeding and manual mixing of feed may face the risk of infection. Relevant studies have shown that the main way for various swine fevers to spread between pig farms is through pig farm personnel;

[0006] 2. It is difficult to configure individual ingredients and feed them individually if the dry feed line is fed uniformly. Weight control can only be achieved by adjusting the feeding amount.

[0007] The above problems reduce the pertinence and safety of boar feeding, and thus affect boar feeding. Summary of the invention

[0045] The basic principles and advantages of this solution: 1. This solution includes a transport unit, a feeding unit, a collection unit and a management terminal; the transport unit is used to transport the feed to the troughs of each pig house through a transport pipeline, and an electric control valve is provided on the transport pipeline above each trough; the electric control valve is connected to a controller; the controller is used to control the opening and closing and opening size of the electric control valve, so as to achieve different feed amounts. Although the feed is transported and distributed after centralized mixing, different feed amounts can be delivered to pigs in different pig houses by controlling the opening and closing time and opening size of the electric control valve, so as to meet the different feeding requirements of different pigs and facilitate weight control by adjusting the feed amount;

[0046] In addition, a feeding unit is provided above the trough of each pig house for feeding the trough. Specifically, the feeding unit includes: a tank body, a delivery pump, an electric-controlled water valve and a stirring device; the tank body is used to store the materials to be fed, such as medicines or nutrients; the discharge port of the tank body is connected to a discharge pipeline to transport the materials to the trough; a delivery pump and an electric-controlled water valve are provided on the discharge pipeline; the delivery pump is used to pump the materials in the tank body into the trough through the discharge pipeline; the electric-controlled water valve is also connected to a water pumping pipe, and the other end of the water pumping pipe is connected to a water source. The electric-controlled water valve extracts water from the water source and adds it to the mixed materials in the tank body, and then transports the mixed materials to the trough, and the stirring device mixes the materials and feed in the trough evenly to ensure the material intake of the pigs when eating, and at the same time realizes the separate configuration of feed for each boar, which meets individual requirements, is convenient for adding separate nutrients to improve physical fitness and control weight, and reduces artificial feeding, isolates the source of infection or transmission to a certain extent, and improves the safety of boar feeding;

The staff can obtain the boar's feeding time through the management terminal, and then determine whether it is sick or abnormal. If sick or abnormal, the staff can deal with it in time and adjust its feed through the feeding unit, thereby further improving the targetedness and safety of feeding.

[0048] 2. The water source connected to the electric water valve is a hot water source. After the hot water is pumped in and mixed with the materials stored in the tank, it is cooled and then pumped into the feed trough through a delivery pump, thereby sterilizing and disinfecting the added materials to ensure the safety of the boars' eating.

[0049] 3. The collection unit of this scheme is also used to collect the boar's feed intake and send it to the management terminal for storage. The management terminal will also judge whether the boar's feeding time is in line with the preset feeding time range based on the feeding time. If not, it will issue an abnormal feeding time reminder. It also judges whether the boar's feed intake is in line with the preset feed intake range based on the feed intake. If not, it will issue an abnormal feeding amount reminder, thereby promptly reminding the staff that the boar may be sick or abnormal, which is convenient for management personnel to deal with it in time and improve system security.

[0050] 4. The collection unit completes the collection of feeding time and feeding amount through the pressure detection device, timer and controller, with simple structure and low cost.

[0051] 5. The stirring device is provided with a rotating shaft on the notch of the trough, and a number of semicircular rings are evenly arranged on the rotating shaft. The motor drives the rotating shaft to rotate, thereby stirring the feed in the trough to mix the medicine and the feed. The number of semicircular rings evenly arranged can be set according to demand. When there are multiple pigs in a pig house, the semicircular rings divide the trough into several small troughs, so that the pigs can feed separately when eating, prevent scramble, and ensure that every pig can eat.

[0074] The feeding unit is arranged above the feeding trough 1 of each pig house and is used for feeding the feeding trough 1 .

[0075] Specifically, the feeding unit includes: a tank, a delivery pump, an electric-controlled water valve and a stirring device;

[0076] The tank body is used to store the added materials, wherein the materials may be medicines or nutrients, etc.; the discharge port of the tank body is connected to a discharge pipeline to transport the materials to the feed tank 1;

[0077] The discharge pipeline is provided with a delivery pump and an electric-controlled water valve, both of which are electrically connected to the controller;

[0081] A stirring device is used to mix the materials and feed in the trough 1 evenly; Figure 3 As shown, the stirring device includes: a rotating shaft 2 and a motor 3;

[0082] The motor 3 is electrically connected to the controller, and the controller is also used to control the start and stop and the speed of the motor 3; the output shaft of the motor 3 is connected to the rotating shaft 2, and the rotating shaft 2 is transversely arranged on the notch of the trough 1;

[0083] Several semicircular rings 4 are evenly spaced on the rotating shaft 2; and the diameter of the semicircular ring 4 is smaller than the inner diameter of the trough 1, and the surface is smooth, so that it can rotate in the trough 1; when stirring is required, the controller starts the motor 3, and the motor 3 drives the rotating shaft 2 to rotate, and then drives the semicircular ring 4 to rotate, and stirs the feed and medicine in the trough 1, so that the feed and medicine are evenly mixed to ensure the feeding effect of the medicine; when stirring is not required, the semicircular ring 4 is above the trough 1, and the trough 1 is divided into several small trough 1 areas, so that the boars can feed separately when feeding, prevent looting, and ensure that each boar can feed.

In addition, in other embodiments, a spiral stirring blade is also provided on the rotating shaft 2, and the radius of the stirring blade does not exceed 3cm, and the surface is smooth, so that the mixing and stirring effect can be enhanced.

[0084] A collection unit is used to collect the boar's feeding time and feeding amount, and send them to the management terminal for storage;

[0085] Specifically, the acquisition unit includes: a pressure detection device and a timer;

[0086] The controller is electrically connected to the pressure detection device and the timer respectively;

[0087] The pressure detection device is arranged at the bottom of the trough 1, and is used to detect the pressure of the trough 1, and generate a pressure signal, and send it to the controller; in this embodiment, the pressure sensor is used, and in other embodiments, the pressure detection device can use a weighing sensor, so that the pressure signal can be directly converted into a weight value;

[0088] The controller is connected to the management terminal and is also used to determine whether the pressure value belongs to the first preset pressure range according to the pressure signal. If so, the timer is started, and the timer is also determined according to the pressure signal whether the pressure value belongs to the second preset pressure range. If so, the timer is turned off; the timing of the timer is obtained as the feeding time, and the feeding time is sent to the management terminal; wherein the first preset pressure range is the corresponding amount of feed fed to the boar at a time and its error range, for example: the amount of feed fed to a boar at a time is 2000g. Considering that there is a certain error in feeding, the feed amount range can be set to 2000g±100g, which is converted into a corresponding pressure range, and the pressure range of the deadweight of the feed trough 1 is added to determine the first preset pressure range; the second preset pressure range is the pressure corresponding to the deadweight of the feed trough 1 and its error. Considering that there may be a small amount of feed residue in the feed trough 1, the second preset pressure range is the pressure corresponding to the deadweight of the feed trough 1 and its error;

[0089] In other embodiments, the controller is also used to determine whether the timing of the timer exceeds a preset timing range. If so, an abnormal feeding signal is generated and sent to the management terminal; the management terminal issues an abnormal feeding reminder based on the abnormal feeding signal, thereby facilitating the staff to timely monitor whether the boar is eating normally, wherein the preset timing range is confirmed based on the corresponding boar and the historical collection time.

[0090] The controller is also used to identify the total feed amount according to the pressure signal, and to identify the total feed reduction according to the changes in the total feed amount and the pressure signal, and to use the total feed reduction as the feed intake, and to send the feed intake to the management terminal; specifically, the pressure value of the total feed amount is obtained by subtracting the pressure value corresponding to the feed trough 1 from the pressure signal, and then the weight corresponding to the pressure value is obtained by conversion; the total feed reduction is identified according to the changes in the total feed amount and the pressure signal, and the pressure signal decreases as the pig eats. When the pressure signal does not change within a preset time, the current feed amount is obtained according to the current pressure signal, and then the total feed reduction is obtained by subtracting the current feed amount from the total feed amount; the preset time is set according to demand, and is set to 20 minutes in this embodiment. If the boar does not continue to eat within 20 minutes, it is determined that the boar has completed eating, so the total feed reduction can be obtained.

[0091] The management terminal is also used to determine whether the boar's feeding time is within the preset feeding time range according to the feeding time. If not, an abnormal feeding time reminder is issued; the preset feeding time range is selected according to the corresponding boar's historical feeding time data; for example, if the average value of the corresponding boar's historical feeding time data is 10 minutes, and the overall data fluctuates within this range by no more than 5 minutes, the preset feeding time range is set to 5-15 minutes;

[0092] It is also used to judge whether the boar's feed intake meets the preset feed intake range according to the feed intake. If not, an abnormal feed intake reminder is issued. The preset feed intake range is selected according to the corresponding boar's historical feed intake data, which is the same as the preset feeding time range setting, and will not be repeated here.

[0095] Embodiment 2

[0096] This embodiment is basically the same as the above embodiment, except that: it also includes: an electronic ear tag and a weak electric shock device;

[0097] The electronic ear tag and the weak electric shock device are both set on the piglet; in this embodiment, the electronic ear tag is set on the pig's ear, the weak electric shock device is set on the pig's buttocks, and the weak electric shock device is connected to two elastic bands, which are respectively sleeved on the two hind legs of the pig.

[0099] A weak electric shock device comprises: a shell, wherein electrodes, a switch, a power supply and a main control module are arranged in the shell; the power supply is connected with the electrodes and the main control module, and a battery arranged in the power supply shell and a solar cell are also arranged on the top surface of the shell; a through hole is arranged at the bottom of the shell, and the electrode contacts the pig's back through the through hole; the electrode is connected with the power supply, and a resistor and a switch are connected in series on the connection line, and the switch is connected with the main control module; the main control module is also used to control the opening and closing of the switch; wherein when the electrode is applied, it is a weak electric shock, which will not cause harm to the pig, and the maximum voltage of the weak electric shock is 8V, and the maximum voltage of the weak electric shock to the piglet is 4V;

[0100] With the trough 1 as the center, a receiving device is arranged within the second preset range, which is used to receive the radio frequency signal within the second preset range centered on the trough 1; specifically, in this embodiment, the receiving device is arranged on the side wall of the trough 1, and the second preset range is set according to user needs, but needs to cover the trough 1; the receiving device is electrically connected to the controller; in this embodiment, the electronic ear tag adopts an RFID electronic ear tag, and the receiving device adopts an RFID receiving device;

[0101] The controller is also used to start the receiving device and control the start of the drain valve when the central liquid material conveying subsystem and the material trough 1 are disinfected; when the receiving device receives the radio frequency signal emitted by the electronic ear tag of the pig within the second preset range, it triggers the controller to generate an expulsion signal and sends it to the main control module of the electronic ear tag of the corresponding pig; in other embodiments, the controller is also used to identify the strength of the radio frequency signal received by the receiving device, and control the voltage during the electrode electric shock according to the strength of the radio frequency signal. Specifically, a variable resistor is provided in the circuit between the electrode and the power supply, and the voltage is controlled by controlling the size of the variable resistor.

[0102] The main control module controls the switch to start (close) according to the driving signal, and the electrode is energized to apply weak current electrode to the pig, which is painful but will not harm the pig; and the control switch is started at intervals, and the time of a single start does not exceed the preset start time, which is 2s in this embodiment, and the interval time is 10s, to prevent long-term electric shock from harming the pig;

[0103] Disinfectant and clean water are introduced to disinfect the central liquid material conveying system and the feed trough 1, and the disinfectant and clean water are discharged through the drain valve. At the same time, in order to prevent pigs from accidentally ingesting disinfectant and clean water, when the pigs approach the second preset range centered on the feed trough 1, weak electric shocks are performed to drive the pigs away, thereby preventing the pigs from approaching the feed trough 1 and accidentally ingesting disinfectant and clean water, thereby protecting the safety of the pigs and completing the disinfection of the central liquid material conveying system and the feed trough 1 at the same time.

[0104] Embodiment 3

[0105] This embodiment is basically the same as the above embodiment, except that: during the feeding process, the controller is also used to start the pressure detection device and the receiving device;

[0106] According to the pressure signal transmitted by the pressure detection device, the feed amount and the feed reduction amount are identified; wherein the feed amount is the total feed amount, and the feed reduction amount is the amount of feed put in minus the current feed amount; in addition, in other embodiments, the total feed amount can also be calculated according to the flow rate corresponding to the time and size of the controller controlling the opening of the electronically controlled valve;

[0107] Identify pigs eating based on radio frequency signals;

[0108] Based on the identified feeding pigs, feed amount and feed reduction, it is determined whether the pigs are overeating or eating alone. If so, a driving signal is generated and sent to the main control module of the electronic ear tag of the corresponding pig; specifically, during the feeding process, after the currently feeding pigs are obtained, the feed reduction amount is obtained, and the feed reduction amount is evenly distributed to the currently feeding pigs, so as to record the feed intake of each pig and determine whether the pigs are overeating; after the currently feeding pigs are obtained, the number of currently feeding pigs and the feed intake of each pig in the pig house are determined. If the feed intake of each pig in the pig house does not meet the preset feed intake requirement and the number of pigs is one, it is determined that the pig is eating alone;

[0109] The main control module controls the switch to start (switch off, line on) according to the expulsion signal, and the electrode is energized to conduct weak current to the pig, which is painful but will not harm the pig, thus expelling the pig that eats too much or eats alone, preventing the pig from eating too much and causing gastrointestinal burden and illness, and also preventing the pig from eating alone and affecting the eating of other pigs, thus ensuring the healthy breeding of pigs.

[0110] In addition, in other embodiments, the controller is also used to control the voltage of the electrode during electric shock, and the voltage of the electric shock during the disinfection of the central liquid material delivery system and the feed trough 1 is greater than the voltage of the electric shock during the feeding process, because the harm of accidentally ingesting disinfectant and clean water is far greater than overeating and eating alone, so a higher intensity electric shock is used to prevent pigs from accidentally ingesting. And as a domesticated creature, pigs will form inertia after multiple electric shocks, which is more conducive to the domestication of pigs.

[0112] This embodiment is basically the same as the above embodiment, except that it further includes: an environment indicating device;

[0113] The environment indicating device is electrically connected to the controller;

[0114] The controller is also used to start the environment indication device to indicate the pigs when the central liquid material delivery subsystem and the feed trough 1 are disinfected;

[0115] Specifically, the environment indicating device includes: a player and a blowing device, both of which are connected to the controller; in this embodiment, the player is set on the fence of the pig house, and the blowing device is set on the fence contacted by the trough 1 of the pig house to blow air into the pig house, and a hot air blower is used in this embodiment to prevent the pigs from getting sick due to the blowing of cold air;

[0116] The controller starts the player and the blowing device when the central liquid material conveying subsystem and the material tank 1 are sterilized;

[0117] A player, used to play dispersing music and instruct the pigs not to approach the feed trough 1;

[0118] The blowing device is used for blowing air to instruct the pigs not to approach the feeding trough 1.

[0119] Every time the central liquid material conveying subsystem and the feed trough 1 are disinfected, the environmental indication device is activated, the sound environment and airflow environment in the pig house change, and when the pigs approach the feed trough 1 in the changed environment, a weak electric shock will be triggered, thereby domesticating the pigs and making them develop the habit of not approaching the feed trough 1 in the changed environment, thereby reducing the number of times they are shocked by weak electric shocks. However, during daily eating, the environment in the pig house will not change as described above, and the pigs can approach the feed trough 1 to eat without being shocked by weak electric shocks.

[0120] In addition, in other embodiments, the receiving device is further used to receive radio frequency signals within a third preset range and a fourth preset range centered on the material tank 1; the diameter of the fourth preset range is greater than the diameter of the third preset range, and the diameter of the third preset range is greater than the diameter of the second preset range;

[0121] The controller starts the receiving device when the central liquid material conveying subsystem and the material tank 1 are sterilized. If the receiving device receives a radio frequency signal within a fourth preset range, the controller is triggered to start the player;

[0122] If the receiving device receives a radio frequency signal within the third preset range, the controller is triggered to start the blowing device;

[0123] If the receiving device receives the radio frequency signal emitted by the electronic ear tag of the pig within the second preset range, the controller is triggered to generate a driving signal;

[0124] Thus, a multi-level expulsion is formed. First, voice instructions are given. If the pig continues to approach the trough 1, hot air instructions are given; if the pig continues to approach the trough 1, weak electric shock is given. The number of expulsions of pigs is reduced as much as possible to prevent harm to the pigs due to expulsion, and it is also easier to domesticate the pigs.
