Description

[0002] Currently, traditional artificial feeding relies on experience to allocate milk amounts, making it difficult to accurately match the nutritional needs of fawns at different growth stages. While mechanized feeding equipment can achieve basic quantitative feeding, it lacks the ability to identify individual fawns, resulting in weaker fawns not getting enough milk or stronger fawns overfeeding, highlighting the problem of uneven development within the group.

[0003] Conventional feeding devices generally suffer from poor milk temperature control and uneven mixing. Open heating systems are prone to localized overheating and spoilage, and insufficient mixing can cause fat separation. Furthermore, the pipes and containers have many hard-to-clean areas, leaving milk residue that breeds bacteria, significantly increasing the risk of digestive tract diseases in fawns.

[0004] Existing semi-automatic equipment requires manual operation for tasks such as ear tag verification, milk temperature adjustment, and residual liquid cleaning, with a single feeding taking more than 20 minutes. Mechanical valves are prone to clogging and failure, sensors have weak anti-interference capabilities, frequent maintenance interrupts continuous operation, and the equipment is poorly suited for large-scale farming scenarios.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] like Figure 1 and Figure 2 As shown, this embodiment provides a fully automatic fawn feeding device, including a housing 1;

[0039] The top of the box 1 is provided with a milk adding pipe 3 and a water adding pipe 4, at least two side walls are equipped with multiple ear tag readers 7, and a touch screen display 5 is installed on the front. A PLC controller 6 is fixedly installed on the inner side below the touch screen display 5.

[0040] The box 1 is equipped with a milk mixing chamber. The top of the milk mixing chamber is equipped with a liquid level sensor 12, and a stirrer 2 is vertically installed in the center.

[0041] The sidewall of the milk mixing chamber is covered with a heater 13, and the bottom is connected to an integrated flow meter solenoid valve 8;

[0042] like Figure 3 As shown, the integrated flow meter solenoid valve 8 includes a flow meter core 8-1, a solenoid valve core 8-2, a connecting pipe 8-3, a flow meter external connecting pipe 8-4, and a solenoid valve external connecting pipe 8-5;

[0043] A temperature sensor 11 is installed at the end of the flow meter external connector 8-4, and a silicone nipple 9 is connected to the solenoid valve external connector 8-5.

[0044] The bottom of the milk mixing chamber is laterally connected to a wastewater discharge pipe 10;

[0045] The PLC controller 6 connects to and controls the stirrer 2, the touch screen display 5, the ear tag reader 7, the integrated flow meter solenoid valve 8, the temperature sensor 11, the liquid level sensor 12, and the heater 13.

[0046] This device eliminates individual nutritional imbalances through automated identification and quantitative feeding, eliminates milk hygiene risks through constant temperature mixing and closed-loop clean delivery, and significantly reduces the burden of manual operation through intelligent control of the entire process, ultimately achieving scientific, healthy, and efficient management of fawn farming.

[0047] The following provides a further detailed description of each structure of the aforementioned device;

[0048] In this embodiment, the housing 1 is made of food-grade 304 stainless steel with a thickness of 3-5mm, and the inner surface is mirror-polished to meet food hygiene standards; the touch screen 5 is an IPS capacitive touch screen with a resolution of 800×480, which communicates with the PLC controller 6 through an RS232 interface for parameter setting and feeding monitoring display.

[0049] like Figure 4 As shown, the stirrer 2 includes a base 2-1, a drive motor 2-2, and a stirring paddle 2-3;

[0050] The drive motor 2-2 is fixed on the base 2-1. It is a 57BYG stepper motor and equipped with a TMC2209 silent drive chip. The output shaft is coaxially connected to the stirring paddle 2-3. The stirring paddle 2-3 has a spiral blade structure, and its end is 5-10mm away from the bottom of the milk mixing chamber.

[0051] In this embodiment, both the milk adding pipe 3 and the water adding pipe 4 are silicone flexible tubes, and both have a filter screen with a pore size ≤0.5mm at the inlet end.

[0052] In this embodiment, the PLC controller 6 adopts the Siemens S7-1200 series programmable logic controller, which includes an analog input module, a digital output module, a communication module and control logic, and is used to collect and control various sensors and actuators in real time.

[0053] Specifically, the extended configuration of PLC controller 6 includes: an analog input module SM1231 for connecting temperature sensor 11 and liquid level sensor 12, supporting PT1000 signal input; a communication module CM1241 for connecting ear tag reader 7 via RS485 interface using Modbus-RTU protocol; and a digital output module SM1223 for driving stirrer 2-2, integrated flow meter solenoid valve 8-2, and wastewater pipeline electric butterfly valve, with an output response time ≤2ms.

[0054] Furthermore, the PLC controller 6 is sealed in an IP54-rated electrical control box and has a built-in PID temperature control algorithm and individualized feeding logic program.

[0055] In this embodiment, the ear tag reader 7 is an RFID reader with an effective identification distance of 10-30cm and an identification response time of ≤0.5s. A specific model can be MFRC-522, operating at a frequency of 13.56MHz, and its matching ear tag is a passive electronic tag.

[0056] In this embodiment, the flow meter core 8-1 and the solenoid valve core 8-2 of the integrated flow meter solenoid valve 8 are integrated in series via a connecting pipe 8-3. The flow meter core (8-1) can be a Coriolis mass flow meter, and the solenoid valve core (8-2) can be a normally closed direct-acting valve.

[0057] The specific process of the solenoid valve 8 of the volumetric flow meter includes:

[0058] When the PLC controller 6 calculates the precise amount of milk required for the fawn based on the fawn identification information obtained by the ear tag reader 7, it sends an opening command and target flow value to the integrated flow meter solenoid valve 8. The solenoid valve core 8-2 is energized and opened upon receiving the digital output signal from the PLC. Milk then flows from the bottom of the milk mixing chamber into the flow meter core 8-1 through the external flow meter connector 8-4. The flow meter core 8-1 measures the mass flow rate of milk flowing through the connecting pipe 8-3 in real time with high precision and continuously feeds the flow signal back to the PLC controller 6. The PLC dynamically compares the received real-time flow data with the preset target value. Once the cumulative flow reaches the set value, the PLC immediately sends a closing command to the solenoid valve core 8-2, and the solenoid valve quickly de-energizes and closes, precisely terminating the milk output.

[0059] Meanwhile, a temperature sensor installed at the end of the flow meter external connector 8-4 continuously monitors the temperature of the milk about to flow out, providing final temperature assurance. Finally, a measured amount of milk at the appropriate temperature is delivered to the silicone nipple 9 through the solenoid valve external connector 8-5 for the fawn to suckle.

[0060] In this embodiment, the silicone nipple 9 is detachably connected to the external pipe 8-5 of the solenoid valve via a quick-release connector, and its surface is provided with an anti-slip texture.

[0061] In this embodiment, the wastewater discharge pipe 10 is equipped with an electric butterfly valve, which can be a VTON VF3300 series valve, driven by a gear reduction motor, and electrically connected to the PLC controller 6.

[0062] In this embodiment, the temperature sensor 11 is a PT1000 platinum resistance temperature sensor, and the liquid level sensor 12 is a capacitive liquid level sensor.

[0063] like Figure 5As shown, the heater 13 includes a housing 13-1, a ceramic sealing layer 13-2, a PTC heating element 13-3, and a wire 13-4; wherein, the housing 13-1 is covered with a corrosion-resistant coating made of polytetrafluoroethylene.

[0064] Specifically, the outer shell 13-1 is made of aluminum alloy 6061-T6, the PTC heating element 13-3 is made of barium titanate ceramic, the rated power is 800W, and the surface temperature is automatically controlled below 150℃; the anti-corrosion coating 13-1 adopts a spraying process and meets the GB / T 1771-2007 salt spray resistance test; and the wire 13-4 is a silicone rubber insulated high temperature resistant wire.

[0065] The heater 13 heats the sidewalls of the milk mixing chamber via its PTC heating element 13-3. Upon startup, the PLC controller 6 sets a target temperature value based on a preset optimal feeding temperature for fawns. A PT1000 platinum resistance temperature sensor 11, installed inside the milk mixing chamber, monitors the milk temperature in real time and transmits an analog signal to the PLC. The PLC's built-in PID temperature control algorithm continuously calculates the deviation between the sensor's measured value and the target setpoint, and dynamically adjusts the power output to the heater 13 accordingly.

[0066] The PTC heating element 13-3 has a positive temperature coefficient; its resistance increases sharply as the temperature approaches its Curie point, automatically limiting power and achieving self-limiting temperature protection for the surface. The aluminum alloy housing 13-1 and the PTFE anti-corrosion coating ensure the heater's corrosion resistance in humid environments containing milk vapor. The wire 13-4 safely transmits electrical energy. Through precise PID control by the PLC and the self-limiting temperature characteristics of the PTC material, the milk is efficiently and stably heated and maintained at the set constant temperature.

[0067] The following provides a further explanation of the specific working process and principle of the aforementioned fully automatic fawn feeding device;

[0068] 1) Work process;

[0069] When a fawn wearing a passive RFID ear tag approaches the feeding device, an ear tag reader mounted on the side wall quickly reads the ear tag information within its effective range and transmits the identified individual number to the PLC controller via an RS485 interface (Modbus-RTU protocol). The PLC determines the corresponding milk requirement for that fawn based on a pre-set individualized feeding logic program. Subsequently, the PLC controls the actuators on the milk and water supply pipes to inject milk powder and water into the milk mixing chamber inside the stainless steel tank according to a set ratio. A level sensor monitors the liquid level in the mixing chamber in real time.

[0070] After injection, the stirrer is activated to mix thoroughly. At the same time, the PTC heater covering the side wall of the mixing chamber starts working under the precise adjustment of the PLC's built-in PID temperature control algorithm. The PT1000 platinum resistance temperature sensor continuously monitors the temperature of the mixing chamber and feeds the signal back to the PLC to ensure that the milk is heated and maintained at the set suitable breastfeeding temperature.

[0071] 2) Working principle:

[0072] The core working principle of this device lies in the closed-loop intelligent control and integrated precise execution of the entire process by the PLC controller. Once the milk reaches the set temperature and uniformity, the PLC sends an opening command and target flow value to the integrated flowmeter solenoid valve based on the identified individual fawn information. The flowmeter core measures the milk flowing through the connecting pipe in real time with high precision and feeds the flow signal back to the PLC. The PLC compares the actual flow rate with the set target flow rate and immediately closes the solenoid valve core when the precise feeding amount is reached, achieving individualized quantitative feeding. The milk is fed to the fawns through a silicone nipple with a quick-release connector. A PT1000 temperature sensor installed on the external pipe of the flowmeter provides final temperature monitoring of the milk to be fed, offering double protection.

[0073] After feeding or periodically, the PLC controls the opening of the electric butterfly valve on the wastewater discharge pipe. Utilizing the residual liquid in the mixing chamber or the injected cleaning water, a self-cleaning process is completed through stirring and discharge. The entire process is monitored and displayed via a touchscreen, ensuring transparent and controllable operation. Ultimately, this achieves the scientific and healthy aquaculture goal of eliminating individual nutritional imbalances, preventing hygiene risks, and reducing labor burden.

Similar or identical parts between embodiments can be referred to interchangeably. For the systems disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the descriptions are relatively simple; relevant parts can be referred to the method section.
