[0002] In modern large-scale pig farms, traditional disinfection methods mainly face the following challenges:

[0027] Please see Figures 1 to 3 This embodiment provides a disinfectant atomizing spraying device for pig farms, comprising:

[0028] The first parallel guide rail 1 is located above the pig pen in the pig farm; the first parallel guide rail 1 includes two parallel first guide rails 2, which are connected to the top beam of the pig farm.

The second parallel guide rail 3 includes two second guide rails 4 perpendicular to the first parallel guide rail 1, with first connecting rods 5 at both ends of the second guide rails 4, forming a square frame shape. The first driving mechanism includes multiple first guide wheels 6 disposed on the lower side of the first connecting rods 5 and cooperating with the first guide rails 2, allowing the second parallel guide rail 3 to slide along the first parallel guide rail 1; it also includes a first rack 7 disposed on the lower side of the first guide rail 2, first servo motors 8 disposed at both ends of the first guide rail 2, and a first gear 9 disposed on the output shaft of the first servo motor 8, the first gear 9 meshing with the first rack 7, the four first servo motors 8 being controlled by a first servo motor driver to form four synchronous motors, the first servo motor driver being controlled by a controller.

[0030] The mobile trolley 10 is slidably connected to the second parallel guide rail 3 via a second drive mechanism and moves along the Y direction on the second parallel guide rail 3. The second drive mechanism includes: several second guide wheels 11 disposed below both ends of the mobile trolley 10 and cooperating with the second guide rail 4; second racks 12 respectively disposed above the second guide rail 4 and parallel to the second guide rail 4; second servo motors 13 disposed on both sides of the mobile trolley 10; and second gears disposed on the output shafts of the second servo motors 13 and meshing with the second racks 12. The two second servo motors 13 are synchronous motors controlled by a second servo motor driver.

[0031] A first magnetic scale 14 is provided on the first guide rail 2, and a second magnetic scale 15 is provided on the second guide rail 4. The moving trolley 10 is provided with a first magnetic scale reading head corresponding to the first magnetic scale 14 and a second magnetic scale reading head corresponding to the second magnetic scale 15. The above-mentioned device is used to provide feedback to the controller for executing displacement control commands.

[0032] The spraying device 16 is fixed on the mobile cart 10 and includes: a medicine storage tank 17 fixedly connected to the mobile cart 10, a peristaltic pump 18 located at the bottom of the medicine storage tank 17, and an atomizing nozzle 19 located on the liquid outlet pipe of the peristaltic pump 18.

[0033] The controller controls the first drive mechanism, the second drive mechanism, and the spraying device 16, and also includes a path planning module 20.

[0034] The path planning module 20 includes: a map building unit 21 for acquiring pigsty spatial layout information, a path generation unit 22 for generating a disinfection path based on the spatial layout information, and a path execution unit 23 for controlling the first drive mechanism and the second drive mechanism to move according to the disinfection path.

[0035] The solution for map building unit 21 uses a Hokuyo UST-10LX type two-dimensional LiDAR, which is installed on the mobile cart 10. The real-time point cloud acquisition module scans the fence structure and uses a rasterization processing algorithm to convert the point cloud into a two-dimensional occupancy grid map.

[0036] The path generation unit 22 is implemented based on the Hokuyo UST-10LX two-dimensional LiDAR. Hardware support also includes a Raspberry Pi CM4 (quad-core Cortex-A72, 4GB RAM) for running SLAM algorithms (such as Gmapping / Cartographer) to build grid maps; real-time path planning (A / D algorithm); processing sensor data fusion (LiDAR+IMU); the communication module uses a CAN bus interface to connect to the motor controller and send speed / steering commands; a Wi-Fi / 4G module for remotely uploading map data or receiving commands; the position of the mobile cart 10 is determined by the first magnetic scale 14 and the second magnetic scale 15.

[0037] The path generation unit 22 further includes a region marking unit for marking region types on a digital map, wherein the region types include: pigpen region, passageway region, sewage outlet region, and feed delivery region. The hardware of the path generation unit 22 also includes an RGB-D camera (such as an Intel RealSense D455). The two-dimensional LiDAR identifies region types through differences in point cloud density (e.g., sparse point clouds in passageway regions, dense point clouds with regular intervals in pigpen regions), and the RGB-D camera identifies region features.

[0038] The path execution unit 23 is executed by the controller.

[0039] The controller further includes a spray volume control module that controls the spray volume based on the area type. The spray volume control module includes the peristaltic pump control module 24 and a liquid flow meter 25 mounted on the outlet pipe. By presetting the spray volume for different areas, the controller, upon reaching a specific area, controls the motor of the peristaltic pump 18 via the peristaltic pump control module 24, and controls the spray volume of the pesticide solution in conjunction with the flow rate of the liquid flow meter 25.

[0040] The medicine storage tank 17 is equipped with a medicine liquid stirring mechanism inside. The stirring mechanism is located on the lid of the medicine storage tank 17, and a third servo motor 26 is installed on the lid. The output shaft of the third servo motor 26 is connected to a transmission shaft 27, which passes through the medicine storage tank 17 and has a stirring paddle 28 mounted on it. The medicine liquid stirring mechanism maintains the uniformity of the medicine liquid, and the third servo motor 26 is equipped with a third servo motor driver.

[0041] The mobile cart 10 is equipped with a driving device 30 controlled by the controller. The driving device 30 includes a variable frequency sound wave generator 29 and an infrared thermal imaging sensor 31 for detecting the pig's position. When the infrared thermal imaging sensor 31 detects a pig at the spraying location, the variable frequency sound wave generator 29 emits a driving sound wave to drive the pig away from that location, thus preventing the disinfectant from spraying onto the pig and affecting its health, and also preventing the pig from blocking the spray and causing any missed disinfection.

[0042] In this embodiment, the controller model used is Advantech UNO-2484G.

[0043] When using the disinfectant atomizing spraying device for pig farms according to this utility model:

[0044] First, the controller constructs a map and plans the path for the pig farm. Then, it fills the medicine storage tank 17 with disinfectant and starts the device, which sprays disinfectant water along the planned path.

[0045] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
