[0020] This utility model provides a feed pretreatment device for yak farming, such as... Figure 1-4 As shown, the feed pretreatment device for yak farming includes: a treatment box 1; a partition 2, which is fixedly installed inside the treatment box 1 and divides the treatment box 1 into a cleaning chamber 3 and a movable chamber 4; multiple cleaning brushes 5, which are rotatably installed inside the cleaning chamber 3; a feed inlet 6, which is opened on the treatment box 1 and is correspondingly arranged to the cleaning chamber 3; a feed hopper 7, which is fixedly installed on the treatment box 1 and is correspondingly arranged to the feed inlet 6; multiple connecting rods 8, which are respectively fixedly installed on the multiple cleaning brushes 5 and are all arranged at the bottom of the treatment box 1; a drive mechanism, which is arranged on the treatment box 1 and is used to synchronously drive the multiple cleaning brushes 5 to rotate; and a discharge mechanism, which is arranged inside the movable chamber 4 and is used to remove the raw materials from the cleaning chamber 3.

[0021] In this embodiment, the processing box 1 serves as the main structure of the entire pretreatment device, providing space for the installation and operation of various functional components such as cleaning, driving, and discharging. Its design allows for efficient feed processing in a closed environment, reducing external contamination and loss. The partition 2 effectively divides the interior of the processing box 1 into a cleaning chamber 3 and an active chamber 4, achieving physical separation of cleaning and discharging functions, ensuring the continuity of the cleaning process and the smoothness of discharging. Multiple cleaning brushes 5 are rotatably installed within the cleaning chamber 3, directly contacting and scrubbing the incoming feed materials, especially leafy greens and root vegetables, effectively removing impurities and dirt. Their number and design can be adjusted according to the type of feed and cleaning requirements to ensure cleaning effectiveness.

This automated cleaning method significantly improves the cleaning speed and effectiveness of feed raw materials, reducing the tediousness and time-consuming nature of manual cleaning. It achieves continuous operation of cleaning and discharging, simplifies the feed pretreatment process, and improves overall processing efficiency.

[0022] In a further preferred embodiment of this utility model, the driving mechanism includes a turntable 9, multiple support legs 10, two fixing plates 11, and a rotary motor 12. The multiple support legs 10 are all fixedly installed on the bottom of the processing box 1, the two fixing plates 11 are all fixedly installed on the multiple support legs 10, the rotary motor 12 is fixedly installed between the two fixing plates 11, the turntable 9 is rotatably installed on the connecting rod 8 fixedly installed on the output shaft of the rotary motor 12, and the turntable 9 is rotatably connected to the connecting rod 8 fixedly installed at the bottom of the multiple cleaning brushes 5.

[0023] In this embodiment, the turntable 9, as one of the core components of the drive mechanism, rotates to drive all the cleaning brushes 5 to rotate synchronously, thus achieving feed cleaning. Support legs 10 provide stable support for the entire pretreatment device. These support legs not only ensure the stability of the device during operation but also provide a mounting base for the drive mechanism via the mounting plates 11. The space between the mounting plates 11 is used to install the rotary motor 12 and serves as a support structure for the turntable 9 and connecting rod 8. The design of the mounting plates 11 enhances the stability of the drive mechanism, preventing swaying and deviation during rotation. The rotary motor 12, as the power source of the drive mechanism, is connected to the turntable 9 via its output shaft, providing power for the rotation of the turntable 9. The selection of the rotary motor 12 should consider the load, speed, and durability requirements of the cleaning operation to ensure cleaning efficiency and equipment lifespan. Through the reasonable layout of the support legs 10, mounting plates 11, and rotary motor 12, the drive mechanism has a compact structure, occupies little space, and is easy to install and maintain inside the processing box 1. The design of the turntable 9 ensures that all cleaning brushes 5 can rotate synchronously, avoiding unevenness in the cleaning process and improving the cleaning effect and feed quality.

[0024] In a further preferred embodiment of this utility model, the discharge mechanism includes a movable port 13, a plurality of hydraulic rods 14, a guide groove 15, a discharge port 16, and a conveying mechanism. The movable port 13 is opened on the partition plate 2. The plurality of hydraulic rods 14 are all fixedly installed in the movable cavity 4. The guide groove 15 is fixedly installed between the plurality of hydraulic rods 14. The discharge port 16 is opened on the inner wall of the movable cavity 4 and is correspondingly arranged with the guide groove 15. The conveying mechanism is arranged on the guide groove 15 and is used to transfer the raw materials in the cleaning cavity 3.

[0025] In this embodiment, the movable port 13 serves as a channel connecting the cleaning chamber 3 and the movable chamber 4. When discharge is required, the movable port 13 allows the cleaned feed material to enter the movable chamber 4 from the cleaning chamber 3 for subsequent transfer or storage. The hydraulic rod 14 controls the height of the guide trough 15 through telescopic movement to ensure that the conveying mechanism does not affect its operation when the cleaning brush is working. The guide trough 15 provides guidance for the transfer of feed material from the movable port 13 to the discharge port 16. Guided by the guide trough 14, the feed material can enter the discharge port in an orderly manner, reducing the need for manual intervention and cleaning, and improving overall work efficiency. The design of the guide trough 15 ensures that the feed material maintains a certain direction and speed during the transfer process, avoiding scattering and accumulation. The discharge port 16 is the final channel for the feed material to leave the pretreatment device, realizing continuous processing and storage of feed. The conveying mechanism is used to transfer the raw material in the cleaning chamber 3 to the discharge port 16 through the movable port 13 and the guide trough 15. The use of the conveying mechanism realizes the automated transfer of feed material, reducing the labor intensity and time cost of manual handling. Meanwhile, the conveying mechanism can adjust its speed and direction as needed to adapt to the requirements of different production scenarios.

[0026] In a further preferred embodiment of the present invention, the conveying mechanism includes two mounting plates 17, two transmission gears 18, a conveyor belt 19, and a drive motor 20. The two mounting plates 17 are fixedly mounted on the guide groove 15, the two transmission gears 18 are rotatably mounted between the two mounting plates 17, the conveyor belt 19 is sleeved between the two transmission gears 18, the drive motor 20 is fixedly mounted on the guide groove 15, and the output shaft of the drive motor 20 passes through the mounting plate 17 and is fixedly connected to any of the transmission gears 18.

[0027] In this embodiment, the mounting plate 17 serves as a base for supporting and fixing other components. It provides a stable mounting platform for the transmission gear 18 and drive motor 20, ensuring their normal operation without wobbling. The robustness and stability of the mounting plate are crucial to the overall performance of the conveying mechanism, ensuring the accuracy and reliability of the transmission gear and drive motor during high-speed operation. The transmission gear 18 transmits power through meshing. As a key component of power transmission, the transmission gear transmits the rotational power generated by the drive motor 20 to the conveyor belt 19, thereby driving its movement. The precise meshing of the transmission gear ensures the efficiency and stability of power transmission, reducing energy loss and noise generation. The conveyor belt 19 achieves its own cyclical movement through the rotation of the gears. As the core component of the conveying mechanism, the conveyor belt is responsible for transporting the raw materials in the cleaning chamber 3 from the movable port 13 through the guide groove 15 to the discharge port 16. The continuity and smoothness of the conveyor belt ensure the smooth transfer of feed raw materials, avoiding blockages and spillage. The drive motor 20 serves as the power source for the conveying mechanism. Through its output shaft, the drive motor 20 converts electrical energy into mechanical energy, driving the transmission gear 18 and the conveyor belt 19. The selection and installation location of the drive motor significantly impact the performance of the conveying mechanism. Proper selection and installation ensure efficient and stable operation while reducing energy consumption and noise. Through the cooperation of the transmission gear and the conveyor belt, rapid and stable transport of feed materials is achieved, improving overall processing efficiency.

[0028] In a further preferred embodiment of the present invention, a drain pipe 21 is fixedly installed at the bottom of the processing box 1, the drain pipe 21 extends into the cleaning chamber 3, and a solenoid valve is fixedly installed on the drain pipe 21.

[0029] In this embodiment, the drain pipe 21 is a fixed mounting component at the bottom of the processing tank 1, allowing it to directly contact the liquid or impurities in the cleaning chamber for easy discharge. A solenoid valve is fixedly mounted on the drain pipe 21. The solenoid valve regulates the flow of the drain pipe by controlling its opening and closing, thereby achieving precise control of the discharge process. The main function of the drain pipe 21 is to discharge accumulated sewage, impurities, or waste liquid generated during the cleaning process from the cleaning chamber 3. This helps maintain the cleanliness of the cleaning chamber and the hygiene of the working environment. Through its combined use with the solenoid valve, the discharge process can be automated. When discharge is required, the solenoid valve is opened to allow the sewage or impurities to be discharged smoothly; after discharge, the solenoid valve closes to prevent external impurities from entering the cleaning chamber. Regularly discharging sewage and impurities from the cleaning chamber helps maintain its cleanliness, thereby improving the cleaning efficiency of feed ingredients.

[0030] In a further preferred embodiment of this utility model, a fan 22 is fixedly installed on the treatment box 1, a three-way pipe 23 is fixedly installed at the exhaust end of the fan 22, two connecting pipes 24 are fixedly installed on the three-way pipe 23, the other ends of the two connecting pipes 24 are respectively connected to the two side walls of the treatment box 1, and valves 25 are fixedly installed on each of the two connecting pipes 24. Two exhaust pipes 26 are fixedly installed in the cleaning chamber 3, and multiple air outlets are opened on each of the two exhaust pipes 26. The two exhaust pipes 26 are respectively fixedly connected to the two connecting pipes 24.

[0031] In this embodiment, the blower 22, as a fixed component on the processing chamber 1, provides airflow power, drawing external air into the processing chamber 1 and discharging it through a pre-designed path to move the raw materials within the cleaning chamber 3. This facilitates contact between the raw materials and the conveying mechanism, ensuring smooth discharge of the cleaned materials. The three-way pipe 23 acts as an airflow distributor, dividing the airflow generated by the blower 22 into two paths, which enter the two sides of the processing chamber 1 through two connecting pipes 24, achieving uniform airflow distribution. Through the distribution effect of the three-way pipe 23, the airflow distribution is more uniform, and the movement of the raw materials within the cleaning chamber 3 is more stable and efficient. This not only improves the cleaning effect but also reduces problems caused by raw material accumulation or stagnation. The connecting pipes 24 serve as airflow transmission channels, introducing the airflow generated by the blower 22 into the processing chamber 1 and discharging it through the exhaust pipe 26. Valves 25 are fixedly installed on each connecting pipe 24 to control the on / off state and flow rate of the airflow. The valves 25 provide flexible airflow control, allowing adjustment of the airflow intensity and direction according to actual needs to meet different movement requirements. The design of the exhaust pipe 26 allows airflow to act more effectively on the surface of the raw materials, propelling them and facilitating the cleaning process. Simultaneously, this design improves airflow efficiency within the cleaning chamber 3, reducing the risk of raw material mold growth due to excessive humidity.

[0032] In a further preferred embodiment of the present invention, the guide groove 15 slides in contact with the inner wall of the movable cavity 4 on one side where the discharge port 16 is provided. The guide groove 15 is inclined. A guide plate is fixedly installed on the outside of the processing box 1. The guide plate is correspondingly provided with the discharge port 16.

[0033] In this embodiment, the design of the guide groove 15 ensures that the moving parts can smoothly run along the trajectory of the guide groove 15 when moving along the moving cavity 4. The guide groove 15 is designed to be inclined, and the inclined guide groove can guide the raw material to move towards the discharge port 16 along a certain inclination angle. When the moving parts move on the guide groove 15, they will move the raw material together, and use gravity to make the raw material flow more easily to the discharge port 16. The inclined setting of the guide groove 15 significantly improves the efficiency of the raw material moving towards the discharge port 16 and reduces the residence time of the raw material in the processing tank 1. This not only helps to improve the cleaning efficiency, but also effectively prevents the raw material from accumulating too much in the processing tank 1, thereby reducing the risk of mold and bacterial growth. The guide plate usually has a guiding function, which can further ensure that the raw material discharged from the discharge port 16 can flow out in a predetermined direction, avoiding the raw material from scattering or splashing during the discharge process. The design of the guide plate simplifies the discharge and collection process of the raw material and improves the work efficiency. At the same time, it also helps to reduce the loss and waste of raw material during the discharge process, further improving the practicality and economy of the entire equipment.

[0034] In summary, compared with related technologies, this device achieves highly efficient and automated cleaning of feed ingredients by driving multiple cleaning brushes to rotate synchronously through a drive mechanism. This significantly improves cleaning speed and effectiveness while reducing the tediousness and time-consuming nature of manual cleaning. The device's internal structure is rationally designed, with a clear separation between the cleaning chamber and the active chamber, enabling continuous cleaning and discharging operations. The discharging mechanism, through a conveyor system, orderly discharges the cleaned feed ingredients, ensuring smooth and efficient discharge. The device is equipped with control components such as solenoid valves and other valves, allowing for flexible adjustment of processes such as wastewater discharge and airflow to meet the needs of different production scenarios. Simultaneously, the design of the wastewater pipe and fan effectively removes wastewater and impurities generated during the cleaning process, maintaining the cleanliness of the cleaning chamber and the hygiene of the working environment. The entire pretreatment device, through automated control and continuous operation, simplifies the feed pretreatment process and improves overall processing efficiency. This not only reduces manual labor intensity but also improves the utilization rate of feed ingredients and product quality.
