Description

Technical Field

[0001] This invention relates to the field of breeding pig feeding technology, specifically to an automatic feeding adjustment mechanism for breeding pig feeding stations. Background Technology

[0002] In modern, large-scale pig breeding, precise feeding and health care are core elements to ensure the health of breeding pigs and improve reproductive efficiency. In daily feeding, in addition to basic liquid feed, various nutritional supplements, health products, or therapeutic drugs need to be precisely added to the feed according to the different physiological stages (such as pregnancy and lactation) or health conditions of the breeding pigs.

[0003] Currently, existing liquid feed feeding systems generally have the following technical problems when adding trace amounts of medication:

[0004] I. Conventional feeding systems are designed for high-volume feed delivery. Their accompanying additive equipment is unable to accurately measure and control trace amounts of medication that account for only 1% to 2% of the total feed, which can easily lead to "excessive" or "insufficient" medication, affecting the health of breeding pigs and even causing waste.

[0005] Second, when changing to different types of medications, traditional pipelines and containers are prone to drug residues if not thoroughly cleaned, causing cross-contamination and posing a potential threat to breeding pigs in sensitive stages (such as pregnant sows).

[0006] Third, the process of adding medicines relies heavily on manual operation, which is not only labor-intensive, but also prone to errors due to human negligence in the selection of medicines, calculation of dosage, and timing of addition.

[0007] Fourth, the cleaning of drug delivery pipelines usually involves rinsing with a large amount of water, which not only consumes a lot of water resources, but is also time-consuming, inefficient, and difficult to guarantee thorough cleaning, especially in dead corners such as pipe bends.

[0017] As a preferred embodiment of the present invention: the smart medicine module includes a plug-in part and a medicine box;

[0018] The connector includes several mating slots fixed on the outer wall of the throat segment. The outer wall of the mating slot away from the throat segment has a USB female chip interface and a receiving groove. The inner wall of the receiving groove has a connecting pipe, and the connecting pipe is connected to the drug injection port. The USB female chip interface is electrically connected to the main control cabinet.

[0019] As a preferred technical solution of the present invention: the medicine box includes a medicine box body, a peristaltic pump motor is fixedly mounted on the outer wall of the medicine box body by screws, a three-axis rotating frame is fixedly mounted on the output end of the peristaltic pump motor, three rollers are respectively rotatably sleeved on the end of the three-axis rotating frame away from the peristaltic pump motor, a pump head housing is sleeved on the outside of the three rollers, a flexible pump tube is sleeved between the pump head housing and the three rollers, a fixing seat is sleeved on the outer wall of the flexible pump tube near the pump head housing and fixedly mounted on the outer wall of the medicine box body, a snap-fit ​​outer shell is fixedly snapped on the outer wall of the medicine box body near the peristaltic pump motor, a flexible medicine inner liner is sleeved between the snap-fit ​​outer shell and the peristaltic pump motor, and the flexible medicine inner liner is inserted and connected to the end of the infusion tubing;

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1 - Figure 11 The automatic feeding adjustment mechanism of the pig feeding station includes a feed pump 2, an electric three-way valve 3 connected to the output end of the feed pump 2, a diversion pipe 4 connected to one side of the output end of the electric three-way valve 3, and a drug injection system 6 connected to several output ends of the diversion pipe 4.

[0045] The shunt tube 4 has at least one output end, and each output end is connected to a drug injection system 6.

[0046] In a preferred embodiment, a self-cleaning unit is also included, which includes a high-pressure air pump and a high-pressure water pump. The output ends of the high-pressure air pump and the high-pressure water pump are both connected to the cleaning port of the flow meter 5. A check valve is also provided between the high-pressure air pump and the high-pressure water pump and the flow meter 5.

[0047] Flow meters 5 are installed at several output ends of the split pipe 4;

[0048] It also includes a main control cabinet 1 for controlling the self-cleaning unit and the drug injection system 6, and the main control cabinet 1 is also electrically connected to several flow meters 5.

[0049] Once a feeding task is completed, the main control cabinet 1 will automatically trigger the cleaning program. First, switch the electric three-way valve 3, disconnect the connection between the electric three-way valve 3 and the feed pump 2, connect the self-cleaning unit and the diversion pipe 4, and then sequentially activate the high-pressure air pump and the high-pressure water pump to execute the pulse cleaning process of "blowing - water mist rinsing - re-blowing". After the cleaning is completed, the system will automatically reset and wait for the next task.

[0050] It should be noted that when the electric three-way valve 3 does not have automatic connection switching, manual connection switching is required;

[0051] When the electric three-way valve 3 has automatic connection switching, it can be directly electrically connected to the main control cabinet 1, and the automatic control connection switching can be realized through the main control cabinet 1.

[0052] In a preferred embodiment: the feed pump 2 includes a base 201, a pump housing 202 is fixedly mounted on the top of the base 201, a drive motor 203 is fixedly mounted on the top of the pump housing 202, an inlet valve 204 is connected to the inlet end of the pump housing 202, and an outlet valve 205 is connected to the outlet end of the pump housing 202.

[0053] In the above structure, the drive motor 203 drives the blades located in the inner cavity of the pump housing 202 to transport the liquid feed located in the inner cavity of the pump housing 202, so that the liquid feed located in the feed bin can be transported. By setting the inlet valve 204 and the outlet valve 205, the on-off control between the feed pump 2, the feed bin and the electric three-way valve 3 can be realized.

[0054] Furthermore, the on / off control between the feed pump 2, the feed silo, and the electric three-way valve 3 can also be achieved through electrical equipment control;

[0055] It should be noted that feed pump 2 can also use other liquid feed conveying devices in the prior art.

[0056] In a preferred embodiment: the two ports of the electric three-way valve 3 are connected to the feed pump 2 and the diversion pipe 4 respectively, and the port located at the top of the electric three-way valve 3 is connected to the output ports of the high-pressure air pump and the high-pressure water pump in the self-cleaning unit.

[0057] By connecting the two ports of the electric three-way valve 3 to the feed pump 2 and the diversion pipe 4 respectively, the resistance when liquid feed is transmitted through the electric three-way valve 3 can be reduced.

[0058] It should be noted that, in addition to the common T-shaped tee, the electric three-way valve 3 can also use a Y-shaped tee. When using a Y-shaped tee, when the output ports of the high-pressure air pump and high-pressure water pump in its self-cleaning unit are connected to the port at the top of the Y-shaped tee, the flow direction of the high-pressure air pump and high-pressure water pump to the diversion pipe 4 should be consistent with the tilt direction of the top port of the Y-shaped tee.

[0059] When the flow direction is consistent with the tilt direction, the high-pressure air and water mist will merge into the main road at high speed, and smoothly change direction with minimal energy loss and enter the main channel of the diversion pipe 4, ensuring that the cleaning medium can carry its maximum kinetic energy to the entire downstream pipeline, thereby achieving the most efficient flushing and stripping effect.

[0060] In a preferred embodiment: the drug injection system 6 includes an online mixer 601, a plurality of smart drug modules 602 are arranged in a ring on the outer wall of the online mixer 601, and the outlet end of the online mixer 601 is connected to a mixture outlet 603.

[0061] In a preferred embodiment: the online mixer 601 includes a throat section 6011, with transition sections 6012 connected to both sides of the throat section 6011, and a connecting section 6013 connected to the side of the transition section 6012 away from the throat section 6011. The outer wall of the throat section 6011 is circumferentially provided with a liquid injection port 6014 corresponding to a plurality of smart medicine modules 602, and the tilt direction of the liquid injection port 6014 is consistent with the flow direction of the liquid feed located in the inner cavity of the online mixer 601.

[0062] In a preferred embodiment: the smart medicine module 602 includes a connector and a medicine box;

[0063] The connector includes several mating slots 6021 fixed on the outer wall of the throat section 6011. The outer wall of the mating slot 6021 away from the throat section 6011 is provided with a USB female chip interface 6022 and a receiving groove 6023. The inner wall of the receiving groove 6023 is provided with a connecting pipe 6024, and the connecting pipe 6024 is connected to the liquid injection port 6014. The USB female chip interface 6022 is electrically connected to the main control cabinet 1.

[0064] To further clarify how the intelligent medicine module 602 in this invention achieves automatic identification and error-proof verification of medicines, the working principle of its core USB chip identification technology is explained in detail below.

[0065] The principle is mainly based on the electrical connection and data exchange between the USB daughter chip module 60215 installed on the main body of the medicine box 6025 and the USB female chip interface 6022 fixed on the docking slot 6021.

[0066] When the operator inserts the medicine box into the docking slot 6021, the physical plug of the USB daughter chip module 60215 on the medicine box will be aligned and plugged into the USB female chip interface 6022 on the docking slot 6021, establishing an electrical path between the two. After the connection is established, the main control cabinet 1 will provide working voltage to the chip in the USB daughter chip module 60215 through the USB female chip interface 6022, activating it from the dormant state.

[0067] The main control cabinet 1 acts as the host in this communication link, while the USB sub-socket chip module 60215 on the medicine box acts as a device.

[0068] The main control cabinet 1 follows the standard USB communication protocol and sends a preset data read command to the chip module. After receiving the command, the chip module will transmit the pre-written drug data in its internal storage unit back to the main control cabinet 1 via the data line.

[0069] The data stored in the chip is structured and contains at least the following key fields: drug concentration, data check code, production batch number, expiration date, and drug name.

[0070] In a preferred embodiment: the medicine box includes a medicine box body 6025, and a peristaltic pump motor 6026 is fixedly mounted on the outer wall of the medicine box body 6025 by screws. A three-axis rotating frame 6027 is fixedly mounted on the output end of the peristaltic pump motor 6026. Three rollers 6028 are respectively rotatably sleeved on the ends of the three-axis rotating frame 6027 away from the peristaltic pump motor 6026. A pump head housing 60210 is sleeved on the outside of the three rollers 6028. A flexible pump tube 6029 is sleeved on. A fixing seat 60211, which is fixedly assembled with the outer wall of the medicine box body 6025, is sleeved on the outer wall of the flexible pump tube 6029 near the pump head housing 60210. A snap-fit ​​outer shell 60216 is fixedly snapped on the outer wall of the medicine box body 6025 near the peristaltic pump motor 6026. A flexible medicine inner liner 60217 is sleeved between the snap-fit ​​outer shell 60216 and the peristaltic pump motor 6026, and the flexible medicine inner liner 60217 is inserted and connected to the end of the infusion tubing 60212.

[0071] The end of the infusion tubing 60212 away from the flexible drug liner 60217 is connected to an outlet nozzle 60213, and a guide seat 60214 for the outlet nozzle 60213 is fixedly mounted on the outer wall of the pump head housing 60210.

[0072] A USB sub-socket chip module 60215 is fixedly mounted on the outer wall of the main body 6025 near the pump head housing 60210.

[0073] In the above structure, the internal chip of the USB daughter socket chip module 60215 stores drug information;

[0074] When the medicine box is inserted into the connector, it is electrically connected to the USB female connector chip interface 6022 via the USB daughter chip module 60215. This enables the USB to automatically identify the medicine information stored in the chip of the medicine box and send it to the main control cabinet 1. The main control cabinet 1 verifies whether the medicine matches the currently executed task and whether it is within its expiration date.

[0075] After the task begins, the main control cabinet 1 dynamically calculates the required drug injection rate based on the real-time liquid flow rate received from the flow meter 5 and the preset drug concentration.

[0076] The main control cabinet 1 sends a speed command to the corresponding peristaltic pump motor 6026.

[0077] The peristaltic pump motor 6026 drives three rollers 6028 to rotate via the three-axis rotating frame 6027. The three rollers 6028 squeeze the infusion tubing 60212 in turn to actively push the medicine into the throat section 6011 area of ​​the online mixer 601 through the outlet 60213.

[0078] By setting up multiple sets of different smart medicine modules 602, the flexible medicine liner 60217 in different smart medicine modules 602 can store different medicine solutions, thereby realizing the adjustment of medicine under different environments and requirements.

[0079] The negative pressure generated during the transfer of liquid feed in the online mixer 601 assists in the suction of the medicine liquid, enabling the medicine liquid to be uniformly mixed with the high-speed flowing liquid feed;

[0080] The negative pressure generated during the transfer of liquid feed in the online mixer 601 is based on Bernoulli's principle.

[0081] When a liquid fluid flows through a pipe whose cross-sectional area gradually decreases and then increases again, the static pressure will decrease significantly at the location with the smallest cross-sectional area and the fastest flow velocity, and may even form a negative pressure lower than atmospheric pressure.

[0082] By injecting the liquid medicine into the negative pressure zone of the online mixer 601, the negative pressure generated when the liquid feed is transferred in the online mixer 601 "pulls" the liquid medicine out, which allows the peristaltic pump to operate with lower energy consumption and less wear, and greatly extends the life of the pump tube.

[0083] Because the back pressure is counteracted or even reversed by the negative pressure, the volume of liquid pushed by the pump in each stroke is more stable and precise, and less susceptible to fluctuations in the main pipeline pressure.

[0084] When the peristaltic pump stops working, the negative pressure environment at the drug injection port 6014 can effectively prevent the liquid material in the connecting pipe 6024 from flowing back into the drug pipeline, acting as a natural "check valve" to keep the drug pipeline clean.

[0085] The 60217 flexible medicine liner uses a flexible liner, similar to the infusion bags used in hospitals. When the peristaltic pump pumps liquid out of the bag, the bag will naturally collapse and shrink, and no pressure difference will be generated inside and outside the container.

[0086] The drug injection system 6 can also employ a micro piston pump or a plunger pump. In this embodiment, the drug injection system 6 includes a pump body containing a piston or plunger driven by a stepper motor. The drug is stored in a drug container connected to the pump body inlet. The pump body outlet is connected via a pipe to the drug injection port 6014 of the online mixer 601. The stepper motor is electrically connected to the main control cabinet 1. During operation, the main control cabinet 1 calculates the required drug injection volume based on the real-time flow rate data fed back by the flow meter 5 and the preset drug addition concentration, and converts it into a drive pulse signal for the stepper motor. Each time the stepper motor receives a pulse, it rotates by a set small angle, thereby pushing the piston or plunger forward a small distance, precisely pressing out a very small volume of drug solution from the pump body outlet and injecting it into the feed in the main flow channel. By controlling the frequency of the pulse signal, the drug injection rate can be precisely controlled, achieving the same automated micro-precision addition effect as the original embodiment, which is linked to the main feed flow rate.

[0087] The drug injection system 6 can also employ an electromagnetic diaphragm metering pump. In this embodiment, the drug injection system 6 includes a diaphragm pump driven by an electromagnet. The drug in the drug container enters the pump chamber through a one-way valve, and the pump outlet is also connected to the drug injection port 6014 of the online mixer 601. The electromagnet's drive circuit is electrically connected to the main control cabinet 1. During operation, the main control cabinet 1 calculates the required drug flow rate based on the data from the flow meter 5 and sends a control signal, such as a pulse width modulation (PWM) signal, to the electromagnet drive circuit. The drive circuit controls the electromagnet to reciprocate at a specific frequency and stroke, thereby driving the diaphragm to vibrate and pumping the drug out in pulses. By adjusting the electromagnet's vibration frequency and / or stroke, the volume of drug pumped out per unit time can be precisely controlled. This method can also achieve the technical effect of dynamically adjusting and automatically and precisely injecting trace amounts of drug according to the main material flow rate.

[0088] For applications requiring extremely high precision or handling high-viscosity pharmaceuticals, the pharmaceutical injection system 6 can also employ a micro-injection pump. In this embodiment, the system includes a mounting base, a standard syringe, and a lead screw mechanism driven by a high-precision stepper motor. The syringe containing the pharmaceutical agent is mounted on the base, its outlet connected to the pharmaceutical injection port 6014 of the online mixer 601, and its push rod is held in place by the push rod end of the lead screw mechanism. The stepper motor is electrically connected to the main control cabinet 1. During operation, the main control cabinet 1 calculates the required injection rate based on data from the flow meter 5 and controls the stepper motor to rotate. The rotation of the motor is converted into uniform linear motion of the push rod through the lead screw and nut mechanism, thereby smoothly pushing the pharmaceutical agent in the syringe into the main channel at a constant rate. This method is particularly suitable for ultra-micro addition at the nanoliter or microliter level, achieving the same precise and automatic control technical objective of this invention.

[0089] Working principle: The outlet of the liquid feed storage tank is connected to the inlet of the feed pump 2 through a pipe. The outlet of the feed pump 2 is connected to the main channel inlet of the diversion pipe 4 through an electric three-way valve 3. Each outlet of the diversion pipe 4 is connected in series to the outlet of the flow meter 5. The outlets of several flow meters 5 are connected to the inlet of the medicine injection system 6. Each outlet of the medicine injection system 6 is connected to the feed trough of each pig pen.

[0090] The main control cabinet 1 issues a command to start the feed pump 2. The feed pump 2 draws liquid feed from the storage tank and provides it with conveying power. The liquid feed flows through the diversion pipe 4 to each medicine injection system 6. The flow rate is measured in real time by the flow meter 5 at the inlet of the medicine injection system 6 and this data signal is sent to the main control cabinet 1. The main control cabinet 1 controls the smart medicine module 602 at the corresponding target pig pen location to output the medicine liquid. The feed mixed with the medicine liquid finally reaches the target pig pen.
