[0002] Pig feed is made by crushing and pressing grains and straw into pellets, which facilitates digestion and absorption by pigs. Existing pig feed production equipment with sterilization functions relies on high-temperature steam to sterilize the feed through penetration and agitation, resulting in poor sterilization effectiveness, slow processing speed, and reduced practicality.

[0003] A search revealed a Chinese patent document (authorization announcement number CN222468813U) for a pig feed processing device with sterilization function. The device includes a support frame, a processing chamber rotatably connected to the inner side of the support frame, and a connecting frame fixedly connected to the upper end of the support frame. Processing components are mounted on the connecting frame and the processing chamber.

The output shaft of the drive motor is fixedly connected to a rotating rod with one end penetrating and extending into the inner side of the processing chamber. A stirring rod is fixedly connected to the outer side of the rotating rod. This device solves the problem that existing equipment cannot sterilize mixed feed. However, the device still suffers from uneven sterilization, poor effect, and slow speed due to the use of high-temperature steam and stirring for sterilization, thus reducing the device's production efficiency.

[0018] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0019] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0020] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0021] A pig feed processing device with sterilization function, such as Figures 1 to 6 As shown, include: Mounting frame 1 has two parallel barrels 6 connected to its inner wall. The ends of the two barrels 6 are rotatably connected to the inner wall of mounting frame 1. The outer sides of the two barrels 6 are provided with feed inlets 5 for feeding and discharging. The feed inlets 5 facilitate the feeding and discharging of raw materials and processed feed.

[0022] Two connecting frames 3 are welded to the outside of the mounting frame 1. The side walls of the two connecting frames 3 are screwed with drive motors 4. The output shaft of the drive motor 4 passes through the side walls of the connecting frame 3 and the mounting frame 1 and is connected to the end of the rotating shaft 12 inside the barrel 6. The end of the rotating shaft 12 is rotatably connected to the inner wall of the barrel 6. By controlling the output shaft of the drive motor 4 to rotate, the connected rotating shaft 12 is driven to rotate inside the barrel 6, thereby completing the stirring of the raw materials inside the barrel 6.

[0023] A spiral stirring paddle 13 is welded to the outside of the rotating shaft 12. The side wall of the stirring paddle 13 is slidably connected to the inner wall of the barrel 6. The spiral stirring paddle 13 can accelerate the tumbling of the raw materials inside the barrel 6 and improve the stirring efficiency. Several through-holes 14 are provided at equal intervals on the outside of the rotating shaft 12. The holes 14 are connected to the air passages provided inside the rotating shaft 12. A coupling is fixed at the end of the rotating shaft 12. The coupling is connected to the output shaft of the drive motor 4. An air passage is also provided inside the coupling. A hollow pipe 2 is welded to the side wall of the connecting frame 3. A gas pipe for conveying high-temperature steam is connected to the side wall of the pipe 2. The other side of the pipe 2 is fixed to the bushing on the outside of the coupling through a connecting pipe, thereby completing the connection between the connecting pipe and the air passage. Through the holes 14 on the outside of the rotating shaft 12, the high-temperature steam can be fully mixed with the feed inside the barrel 6 to improve the sterilization efficiency. High-temperature steam enters the air passage in the center of the rotating shaft 12 through the air passage in the coupling via pipe 2, and is finally ejected through multiple round holes 14 evenly distributed around the outer circumference of the rotating shaft 12. As the rotating shaft 12 rotates continuously and the stirring paddle 13 constantly agitates the feed, the ejected high-temperature steam can achieve dynamic and multi-dimensional full mixing with the feed particles, avoiding sterilization dead zones and greatly improving sterilization uniformity and efficiency.

[0024] A drive gear 7 is rotatably connected to the side wall of the mounting frame 1. A rotary motor 8 is screwed to one side of the drive gear 7. The output shaft of the rotary motor 8 is connected to a fixed shaft welded to the side wall of the drive gear 7. The fixed part of the rotary motor 8 is welded to the side wall of the mounting frame 1 through a connected fixed bracket, thereby ensuring that the rotary motor 8 drives the drive gear 7 to rotate when it rotates. The side wall of the fixed shaft is rotatably connected to the side wall of the mounting frame 1, and the end of the fixed shaft is also fixed to the end of the barrel 6. Thus, the rotation of the rotary motor 8 completes the driving of the barrel 6. The drive gear 7 is also meshed with the driven gear 15. The drive gear 7 and the driven gear 15 have the same module and number of teeth, and are precisely meshed to ensure that the two barrels 6 can be driven to rotate synchronously, at the same speed, and in opposite directions by a single rotary motor 8. The transmission is stable and reliable. The driven gear 15 is also fixed to a fixed shaft connected to the barrel 6. Thus, the barrel 6 is rotated inside the mounting frame 1 by the drive of the rotary motor 8. With the help of the drive motor 4, the barrel 6 and the rotating shaft 12 rotate in opposite directions, which further improves the efficiency of feed mixing inside the barrel 6 and the uniformity of contact between high-temperature steam and raw materials, making it easy to use.

[0025] During equipment operation, all motors are coordinated and controlled by a central controller: the rotary motor 8 starts, driving the two barrels 6 to rotate in opposite directions at the same speed via the drive gear 7 and driven gear 15; simultaneously, the drive motor 4 starts, driving the rotating shaft 12 and the stirring paddle 13 to rotate in the opposite direction relative to the barrels 6, forming a strong shear mixing field. The high-temperature steam supply system starts synchronously, and steam is evenly sprayed into the feed through the channels inside the rotating shaft 12. This collaborative working mode greatly enhances the mixing and sterilization effects. During discharge, the rotary motor 8 and drive motor 4 stop, and the linear motor 9, electric push rod 19, and linear motor 18 start in sequence to complete the positioning of the discharge plate 11 and the rapid ejection of the feed.

[0026] To accelerate the discharge speed, a linear motor 9 is fixed to the side wall of the mounting frame 1. The moving part of the linear motor 9 is welded to a mounting block 10 that is slidably connected to the inner wall of the mounting frame 1. An electric push rod 19 is embedded inside the mounting block 10. The telescopic part of the electric push rod 19 is movably connected to the discharge plate 11. The other end of the discharge plate 11 is slidably connected to a connecting shaft 16. The end of the connecting shaft 16 is fixed to the inner wall of the mounting frame 1. A fixing plate is also welded to the inner wall of the mounting frame 1. The side wall of the fixing plate is connected to the other end of the connecting shaft 16. Thus, the horizontal and angular adjustment of the discharge plate 11 can be completed by the linear motor 9 and the electric push rod 19, thereby accelerating the discharge speed. Furthermore, a linear motor 18 is installed on the inner wall of the discharge plate 11. The moving part of the linear motor 18 is fixed with a moving plate 17. The end of the moving plate 17 slides against the inner wall of the discharge plate 11. The moving plate 17 is driven to move by the linear motor 18, thereby increasing the discharge speed of the feed inside the discharge plate 11. The discharge plate 11 is located at the lower end of the feed inlet 5, and the moving plate 17 is located behind the feed inlet 5, which can prevent the feed from accumulating on the top of the moving plate 17 during discharge, making operation easier. To ensure the safe and stable operation of the equipment, key rotating sealing parts (such as the joint between the rotating shaft 12 and the barrel 6, and the connection between the fixed shaft and the mounting bracket 1) adopt a combination structure of high-temperature wear-resistant sealing rings and mechanical seals, which effectively prevents high-temperature steam leakage and feed powder spillage.

[0027] The drive motor 4, rotary motor 8, linear motor 9, linear motor 18, and electric push rod 19 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. In order to facilitate the inspection, maintenance, and parts replacement of the device, the parts inside a single device are usually from the same manufacturer and of the same model, function, and batch. Therefore, even if there is a certain difference between two or more electrical control devices, the synchronous movement of the electrical control devices can still be maintained under the action of the controller. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail in this utility model. All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology.

[0028] Working principle When using this pig feed processing device with sterilization function, the raw materials for producing pig feed are first conveyed through the feed inlet 5 to the inside of the barrel 6 by the conveying device, and then the feed inlet is closed. At this time, the generated high-temperature steam is transported to the inside of pipe 2 through the air pipe. Pipe 2 is then transported to the air passage set inside the rotating shaft 12 through the connecting pipe, and output through the through-hole 14 of the drag rod set on the side wall of the rotating shaft 12 to complete the sterilization of the raw materials inside the barrel 6. Then, the output shaft of the rotary motor 8 is controlled to rotate, which drives the connected drive gear 7 to rotate. The drive gear 7 is meshed with the driven gear 15. The drive gear 7 and the driven gear 15 are connected to the end of the barrel 6 through the fixed shaft. This drives the barrel 6 to rotate on the inner wall of the mounting frame 1. Then, the output shaft of the drive motor 4 is controlled to rotate, which drives the rotating shaft 12 connected to the output shaft of the drive motor 4 to rotate. A spiral stirring paddle 13 is welded to the outside of the rotating shaft 12, which completes the stirring of the raw materials inside the barrel 6. The opposing movement of the barrel 6 and the stirring paddle 13 further accelerates the stirring of the device. Finally, after the feed production is completed, the feed is discharged through the feed inlet 5. The linear motor 9 is controlled to drive the mounting block 10 to move. An electric push rod 19 is installed inside the mounting block 10. Through the cooperation of the electric push rod 19 and the linear motor 9, the discharge plate 11 is adjusted. The discharge plate 11 is also equipped with a linear motor 18. The linear motor 18 drives the moving plate 17 to move, thus completing the feed discharge.
