Description

Technical Field

[0001] This utility model relates to the field of aquaculture feeding technology, specifically a precision feeding device for laying hens based on a weight sensor. Background Technology

[0002] In egg-laying hen farming, precision feeding systems dynamically adjust key nutrients such as protein, calcium, and phosphorus in feed based on parameters such as the age of the hens, the egg-laying cycle, and changes in weight, which can improve egg production rate and optimize feed utilization.

[0003] Application No. 202021769964.X discloses an automatic feeding device for laying hens. The device incorporates a mixing tank, a second motor, a mixing roller, a gravity sensor, a PLC controller, and an alarm. When the gravity sensor detects that the feed in the mixing tank is nearly depleted, it electrically connects to the PLC controller, which in turn electrically connects to the alarm. The alarm then prompts the worker to add feed to the mixing tank. The second motor rotates, stirring the feed through the mixing roller. This design improves the situation where feed easily clumps due to prolonged storage or improper storage, or when medication is needed to treat sick laying hens, requiring manual stirring of the feed.

[0004] The weighing structure in the above application only has one set of weight sensors, and the weight distribution is uneven, which is prone to errors and makes it difficult to feed accurately. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1 to 4This utility model provides a technical solution: a precision feeding device for laying hens based on weight sensors, comprising a first base 1 and a second base 2. Two support frames 3 are installed on corresponding sides of the top of the first base 1, and two brackets 5 are installed on corresponding sides of the top of the second base 2. Feed boxes 4 and feed trough racks 6 are respectively installed on the tops of the four support frames 3 and four brackets 5. A first weight sensor 7 and a second weight sensor 8 are respectively installed inside the first base 1 and the second base 2, facilitating the weighing of the remaining and discharged feed, thus improving weighing accuracy. The four support frames 3 and four brackets 5 are respectively located in the center of the first weight sensor 7 and the second weight sensor 8, which is beneficial for the first weight sensor 7 and the second weight sensor 8 to be positioned correctly. The weight distribution sensed by sensor 8 is more concentrated, resulting in more accurate data. Feed chamber 9 and feeding chamber 10 are respectively located inside feed box 4 and feed rack 6. A cover 19 is fitted onto the top of feed box 4. A stirring shaft 20 is rotatably connected to the bottom of cover 19, located inside feed chamber 9, via bearings. Multiple stirring blades 21 are installed on both sides of the stirring shaft 20. A first motor 22 is installed on the top of cover 19. The output end of the first motor 22 is fitted with a bearing seat and fixedly connected to the stirring shaft 20 via a coupling, driving the stirring shaft 20 to rotate. This causes the multiple stirring blades 21 to stir the feed, preventing clumping. The structures of feed chamber 9 and feeding chamber 10 are gyroscope-shaped and trapezoidal, respectively, automatically concentrating the feed and its weight towards the center. This design helps to further improve the accuracy of the weight sensor in weighing feed, while also accelerating the discharge of feed from the feed chamber 9, preventing a large amount of feed residue in the feed chamber 9. A feed pipe 27 is installed on the top of the cover 19, located on one side of the first motor 22, facilitating feed input. A discharge pipe 11 is fixedly connected to the bottom of the feed chamber 9. A feeder 12 is installed at the bottom of the feed box 4, above the feed trough rack 6. A conveying trough 13 is opened inside the feeder 12. One end of the discharge pipe 11 is fixedly connected to the conveying trough 13. A solenoid valve 14 is installed on one side of the discharge pipe 11, facilitating control of the opening and closing of the discharge pipe 11 and the discharge of feed. Multiple equidistant discharge holes 28 are opened inside the feeder 12, located at the bottom of the conveying trough 13. The internal rotation of the conveying trough 13... A conveyor shaft 24 is connected, and a spiral conveyor blade 25 is installed on the outside of the conveyor shaft 24. A second motor 26 is installed on one side of the feeder 12, and the output end of the second motor 26 is fixedly connected to the conveyor shaft 24, driving the conveyor shaft 24 to rotate. While conveying the feed, the feed can be evenly discharged into the feeding chamber 10 through multiple discharge holes 28. A blower 15 is installed on one side of the feed box 4, and a reversing valve 16 is fixedly connected to the output end of the blower 15. A first air duct 17 and a second air duct 18 are fixedly connected to both ends of the reversing valve 16, respectively. One end of the first air duct 17 and the second air duct 18 are fixedly connected to the feed chamber 9 and the discharge pipe 11, respectively. Under the action of the blower 15 and the reversing valve 16, the airflow can be guided into the feed chamber 9 and the discharge pipe 11, respectively.This design helps ensure the feed in the feed chamber 9 remains dry. Simultaneously, the solenoid valve 14, which closes the discharge pipe 11 and the feed chamber 9, allows airflow to accelerate the discharge of remaining feed from the discharge pipe 11, preventing blockages. A filter screen is installed at the input end of the blower 15 to filter out impurities from the air. A PLC controller 23 is installed on the side of the feed tank 4 furthest from the blower 15, and the PLC controller 23 has a display.

[0019] In summary, this precision feeding device for laying hens based on weight sensors works as follows: During operation, the first weight sensor 7 in the first base 1 weighs the feed in the feed bin 4 and feed chamber 9. Simultaneously, the solenoid valve 14 opens the discharge pipe 11, discharging the feed into the conveying trough 13 within the feeder 12. The second motor 26 drives the conveying shaft 24 and the spiral conveying blade 25 to rotate, conveying the feed while simultaneously discharging it evenly through multiple discharge holes 28 at the bottom of the conveying trough 13 into the feeding chamber 10 within the feed trough rack 6. At the same time, the second weight sensor 8 in the second base 2 weighs the feed in the feed trough rack 6 and feeding chamber 10. This is controlled by the PLC controller 23. The first weight sensor 7 and the second weight sensor 8 weigh the remaining amount and the amount of feed discharged, respectively. The operator can judge the accuracy of the value by calculating the sum and the difference. As needed, the first motor 22 can drive the stirring shaft 20 to rotate, which drives multiple stirring blades 21 to stir the feed in the feed chamber 9. The blower 15 introduces airflow into the feed chamber 9 through the reversing valve 16 and the first air pipe 17 to dry the feed. Similarly, after the solenoid valve 14 closes the discharge pipe 11 and the feed chamber 9, the airflow can be introduced into the discharge pipe 11 through the second air pipe 18 to blow the remaining feed in the discharge pipe 11 to flow and discharge.
