Description

Technical Field

[0001] This utility model relates to the field of livestock breeding equipment, specifically to a feed dispensing device. Background Technology

[0002] In modern aquaculture production, group medication has become an important means of disease prevention and treatment. Currently, farms commonly use methods such as injection, feed mixing, drinking water administration, aerosol spraying, and fumigation. Among these, drinking water administration is widely used due to its simplicity, labor-saving, and high efficiency. However, this method also has significant drawbacks: First, drugs have poor stability in water and are easily rendered ineffective by temperature, light, or water composition; second, drug utilization is low, with some drugs being wasted with the water flow and not being fully absorbed by the animals; third, different drugs are prone to chemical reactions in water, leading to interactions, reduced efficacy, or even adverse reactions.

[0003] In contrast, feed mixing improves drug-feed contact efficiency and prolongs the duration of drug efficacy. However, traditional manual drug administration or simple feed mixing equipment suffers from insufficient precision. Manual operation is time-consuming and labor-intensive, making it difficult to achieve precise, stable, and uniform additive effects in large-scale pig farms. Furthermore, traditional equipment relies heavily on experience to control feed volume, often estimating additive dosage based on auger speed, lacking real-time weighing feedback, leading to unstable drug dosages. In addition, existing devices have shortcomings in sealing, protection, and automation. For example, the feed inlet and observation port lack protective measures, making them susceptible to moisture or contamination; the electrical control system has a low protection level, making the equipment prone to damage in humid environments; and the equipment is bulky, making it inconvenient to move and maintain.

[0004] Therefore, there is an urgent need for a device that can automate and precisely administer medication, and integrate with the pig farm's feed delivery system. This device should balance the uniformity, stability, and efficiency of medication delivery, while also possessing excellent structural protection and a user-friendly design to address the shortcomings of traditional drinking water medication and feed mixing equipment in terms of dosage control, protection, and efficiency, thereby improving the overall profitability of pig farms. Utility Model Content

This device achieves precise dosing, automatic linkage, and structural protection by setting up a filling device and filling components, thereby improving drug utilization and breeding efficiency, reducing labor costs, and demonstrating good practicality.

[0006] Specifically, this utility model provides a feed dosing device, which includes a packing assembly, a packing device, and a measuring device. The packing device is disposed inside the packing assembly, and the measuring device is disposed below the packing device. The packing assembly includes a packing box, a storage box, a control box, and a protective cover. The packing box and the control box are arranged side by side, the storage box is located below the packing box and the control box, and the protective cover is located at the discharge port of the packing box. The packing device includes a packing motor, a packing rod, a discharge tee, a mixing hopper, and a feed line stopper. The packing motor is located inside the control box, and its output end passes through the control box and is fixedly connected to the first end of the packing rod. The second end of the packing rod is rotatably connected to the inside of the protective cover via a bearing. The inlet of the discharge tee is located below the second end of the packing rod and is connected to the outlet of the packing box. The outlet of the discharge tee is located above the mixing hopper and the feed line stopper. The outlet of the feed line stopper is connected to the dry material feed line.

[0013] Preferably, the control box has an electrical control box door on its side.

[0014] Preferably, the measuring device is a weighing sensor.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention's filling device combines a filling motor drive with an auger structure, and utilizes a weighing sensor for real-time monitoring, enabling precise drug or additive dispensing. Compared to traditional methods that rely on auger speed to estimate dosage, this device automatically corrects motor operating parameters based on weighing data, ensuring stable and accurate dispensing rates each time. This precise control significantly improves drug utilization, avoids waste and risks associated with over- or under-dosing, and guarantees livestock receive appropriate drug dosages at different growth stages.

[0016] This utility model enhances overall protection and ease of operation through the rational configuration of the top cover, protective cover, storage box, and observation port. The top cover, combined with a nitrogen spring design, allows a single person to easily open or close the hopper, preventing rainwater and debris from entering. The protective cover and electrical control box door effectively improve waterproof and dustproof performance, ensuring long-term stable operation of the equipment.

Detailed Implementation

[0019] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0020] This utility model provides a feed dosing device, such as... Figures 1-4 As shown, the system comprises three main parts: a packing assembly, a packing device, and a measuring device. The packing assembly provides material containment and initial protection; the packing device delivers and dispenses medications or additives; and the measuring device weighs, detects, and calibrates the entire dosing process. These three parts work collaboratively through a well-designed layout to ensure that medications are added to the feed evenly and accurately.

[0021] The packing assembly consists of a packing box, a storage box 5, a control box, and a protective cover 4. The packing box and control box are arranged side-by-side, making the overall device compact and facilitating installation and subsequent maintenance. The storage box 5, located below the packing box and control box, is used to store commonly used drug packaging bags, tools, or maintenance parts, increasing the device's practicality. The protective cover 4 is located at the discharge port of the packing box, effectively preventing external dust and moisture from entering the equipment, while also protecting the safe operation of the packing rod end.

[0022] The filling box, serving as the main container for medicines and feed additives, is equipped with a screen 10 at its inlet. When feeding, operators pour the medicine into the inlet; the medicine first passes through the screen, blocking larger impurities or residual packaging material, preventing them from entering the auger conveyor channel and causing blockages or damage. The screen 10 is fixed to the filling box with a snap-fit ​​structure, facilitating disassembly and cleaning.

[0023] The stuffing box is equipped with an inclined plate inside, with one end higher than the other, forming an incline. Under gravity, the medication automatically slides down the inclined plate to the lowest point. This lowest point corresponds precisely to the starting position of the packing rod, causing the medication to accumulate and ensuring that the auger structure 12 can continuously and evenly deliver the medication to the outlet. The packing rod is located on the bottom surface of the stuffing box and is fixed to the box body by bearings. A material level observation port 6 is provided on the side wall of the stuffing box, allowing operators to visually assess the current remaining material level through the transparent window without opening the top cover.

[0024] In addition, a top cover 1 is provided above the filling box, which is connected to the filling box via a nitrogen spring 9. When adding chemicals, the operator only needs to gently open the top cover 1, which will remain open under the action of the nitrogen spring 9, preventing injury from falling due to gravity. After adding chemicals, the top cover 1 can be tightly closed to prevent external rainwater or impurities from entering the hopper, ensuring internal cleanliness and dry storage of the chemicals.

[0025] Structure and operation of the packing device: The packing device consists of a packing motor 11, a packing rod, a discharge tee 13, a mixing hopper 14, and a feed line stopper 15. The packing motor 11 is installed inside the control box and fixed by a motor bracket. The output end of the packing motor 11 passes through the control box wall and is connected to the first end of the packing rod by a key or bolt. When the packing motor 11 is running, it directly drives the packing rod to rotate.

[0026] The packing rod is horizontally arranged at the bottom of the stuffing box, with spiral auger blades welded or cast onto its outer wall. The drug is continuously pushed forward by the auger structure and ultimately delivered to the stuffing box outlet. The end of the packing rod passes through the interior of the protective cover 4, where bearings provide stable support and low-resistance rotation. This structure prevents the packing rod from vibrating due to its cantilevered state during high-speed operation.

[0027] A discharge tee 13 is installed below the end of the packing rod. The inlet of the discharge tee 13 is connected to the outlet of the packing box, ensuring that the medicine pushed by the auger structure 12 can smoothly enter the discharge tee 13. The discharge tee 13 is designed with a "Y" or "T" shape. The outlet end of the discharge tee 13 is connected to the mixing hopper 14, and the mixing hopper 14 is connected to the feed line stopper 15. In actual operation, the medicine falls into the mixing hopper through the discharge tee 13, and then connects to the main feed line (i.e., the transport feed line) through the feed line stopper 15 to achieve synchronous mixing and conveying of medicine and feed.

[0028] The mixing hopper 14 is located directly below the feed tee 13 and is used to receive the medication and initially mix it with the feed from the feed line to be added. The bottom of the mixing hopper 14 is connected to the feed line stopper 15, which has a valve structure inside to adjust the discharge rate as needed, maintaining a reasonable ratio of medication to feed. Finally, the medication is transported to the pigsty along with the feed through the dry feed line 8 for the pigs to consume.

[0029] Operation of the control box: The control box is located on the side of the stuffing box and integrates electrical components such as a motor drive module, a weighing sensor interface, a power supply module, and a circuit breaker. An electrical control box door 2 is installed on the outside of the control box, and the door 2 is equipped with a sealing strip to ensure good sealing and prevent the ingress of humid air and dust.

[0030] In terms of operation, this device supports both manual and automatic modes: Manual mode: Operators can directly control the start and stop of the packing motor via buttons or the touchscreen on the control box, and can manually set the motor speed for small-scale or short-term drug dosing. Automatic mode: When the feed line system starts, the device automatically links, the packing motor 11 runs synchronously, and the drug is added to the feed according to the set ratio. The weighing sensor 3 collects the drug weight data in real time and feeds it back to the host computer. The system automatically corrects the speed of the packing motor 11 to ensure accurate and stable drug dosing.

[0031] The touchscreen, a 7-inch color LCD screen, is located on the surface of the control box. The screen displays the current drug weight, cumulative dosage, operating status, and historical records. Operators can set parameters via the touchscreen, such as inputting the target dosage, adjusting the speed range of the packing motor 11, and selecting manual / automatic operation modes.

[0032] In addition, the touchscreen is connected to an IoT module, enabling it to upload operational data to a cloud platform. Farm managers can remotely view equipment status, adjust medication plans, and track data via computer or mobile phone.

[0033] Measuring device and calibration function: In this embodiment, the measuring device is a weighing sensor 3, which is installed at the bottom of the stuffing box or below the mixing hopper 14 to detect changes in material weight in real time. The weighing data is transmitted to the control system via a signal line. The host computer compares the data with the set value and automatically adjusts the motor speed and running time to ensure that the dosage is consistent with the target value.

[0034] For example, when the weighing sensor 3 detects that the set dosage has been reached, the control system immediately issues a command to stop the packing motor 11 to prevent overdose. If the dosage rate is too low or abnormal, the system will also issue an alarm to remind the operator to check the remaining material in the hopper or the motor's operation.

[0035] Operation process description: In actual operation, the operator first opens the top cover 1, pours the medicine into the filling box, filters it through the screen 10, and then it enters the hopper. The medicine slides down the inclined plate to the lowest point. The operator selects the operating mode and sets the parameters via the touch screen.

[0036] When in automatic mode and the feed line system is started, the control system receives a start signal and automatically activates the packing motor 11. The auger structure 12 rotates, continuously pushing the medication to the feed tee 13. The medication falls into the mixing hopper 14 and mixes with the passing feed, then is conveyed to the main feed line by the feed line stopper 15, and finally distributed to each pigpen. The weighing sensor 3 detects the dosage in real time, and the system dynamically adjusts the speed of the packing motor 11 based on the feedback data to achieve precise dispensing. Throughout the process, the operator can view the medication dispensing status in real time via the touchscreen and intervene or switch to manual mode when necessary.

[0037] If the operator selects manual mode, they can directly press the control button to start the packing motor 11, or input parameters such as running time and motor speed via the touchscreen to add the drug. This mode is suitable for small-scale trials or special circumstances.

[0038] To enhance user experience and extend equipment lifespan, this invention also incorporates various auxiliary structures. The nitrogen spring 9 supports the top cover 1, making operation safer and more convenient; the storage box 5 provides additional storage space; the drug dosing observation port 7 is located above the protective cover 4, allowing operators to directly observe the mixing effect of drugs and feed; the electrical control box door 2 features a waterproof design, ensuring stable operation of the control system in humid environments.

[0039] In summary, this utility model, through the coordinated design of the filler assembly, filler device, and measuring device, achieves precise drug or additive delivery and automated management. Combined with a user-friendly interface and excellent protective performance, it effectively solves the problems of inaccurate dosage, complex operation, and inconvenient maintenance found in traditional devices, and has high practical value and promising prospects for promotion.

[0040] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
