It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1: Refer to Figures 1-5 As shown: A pellet screening machine for chicken feed production includes a frame 5. A discharge mechanism is provided on the top of the frame 5. The discharge mechanism includes a hopper 6, a scraper 14, and a lead screw 17. A sealing cover 7 is fixedly connected to the bottom of the hopper 6. A screening chamber 1 is bolted to the sealing cover 7. The bottom of the screening chamber 1 is fixedly connected to the frame 5. A second screen 13 is installed inside the screening chamber 1. The bottom of the scraper 14 is slidably connected to the second screen 13. Connecting frames 21 are bolted to both sides of the scraper 14. One end of the connecting frame 21 penetrates the side wall of the sealing cover 7 and connects to... The connecting frame 21 is slidably connected to the sealing cover 7. The connecting frame 21 is threadedly connected to the lead screw 17. One end of the lead screw 17 is rotatably connected to the sealing cover 7. A protective strip 16 is provided above the lead screw 17. One side of the protective strip 16 is fixedly connected to the sealing cover 7. A synchronous belt assembly 11 is fixedly connected to one side of the sealing cover 7. A motor 12 is fixedly connected to one side of the synchronous belt assembly 11. The output shaft of the motor 12 is fixedly connected to one synchronous pulley of the synchronous belt assembly 11, and the synchronous pulley of the synchronous belt assembly 11 is fixedly connected to the end of the lead screw 17.

[0020] The frame 5 is fixedly connected to the bottom of the screening chamber 1, providing stable support for the entire screening mechanism and preventing equipment shaking during screening. The bottom of the hopper 6 is fixedly connected to the sealing cover 7, which is connected to the screening chamber 1 by bolts, forming a closed screening space to prevent feed dust leakage or material spillage. The screening chamber 1 has a built-in screen 13. After the feed enters from the hopper 6, it falls onto the screen 13. The vibrating motor mounted on the side of the screening chamber 1 provides vibration power to achieve preliminary classification. Small particles pass through the screen 13, while large particles / impurities remain on the surface of the screen 13. The lead screw 17 is threadedly connected to the connecting frame 21, and the connecting frame 21 is fixed to both sides of the scraper 14 by bolts. The screw 17, which penetrates the side wall of the sealing cover 7 and slides in contact with it, is converted into linear motion of the connecting frame 21 when it rotates, driving the scraper 14 to slide along the guide of the sealing cover 7. The bottom of the scraper 14 is slidably connected to the screen 13, and scrapes away large particles / impurities remaining on the screen 13 during the sliding process, so that they enter the feed pipe 8 on the side of the screening chamber 1 and are finally discharged from the bottom of the feed pipe 8. The protective strip 16 above the screw 17 is fixedly connected to the sealing cover 7 to prevent feed or dust from directly contacting the screw 17 and avoid thread jamming. The synchronous belt assembly 11 enables the two screws 17 to rotate synchronously, ensuring that the scraper 14 moves smoothly and scrapes without dead corners, avoiding clogging of the screen 13 and improving the initial screening efficiency.

[0021] Example 2: Figures 1-4 As shown, a motor 20 is fixedly connected to one side of the hopper 6. A bevel gear 19 is fixedly connected to the output shaft of the motor 20. A bevel gear 18 meshes with one side of the bevel gear 19. An auxiliary roller 15 is fixedly connected to the shaft of the bevel gear 18. The auxiliary roller 15 is rotatably connected to the hopper 6. A discharge pipe 8 and a discharge pipe 9 are fixedly connected to one side of the screening chamber 1. An extension cylinder 2 overlaps the outer wall of the discharge pipe 9. A vibrating screen 3 is fixedly connected to the bottom of the extension cylinder 2. A screen 10 is installed on the inner wall of the vibrating screen 3. The screen 10 is inclined. A discharge port is provided on one side of the screen 10. The discharge port is opened on one side of the vibrating screen 3. A sealing plate 4 is installed on one side of the discharge port. The sealing plate 4 is connected to the vibrating screen 3 by bolts.

[0022] Motor 20 is fixedly connected to one side of hopper 6. After starting with an external power supply, its output shaft drives bevel gear 19 to rotate. Bevel gear 19 meshes with bevel gear 18, transmitting power to the shaft of bevel gear 18, which in turn drives auxiliary roller 15 to rotate inside hopper 6. Auxiliary roller 15 and the inner wall of hopper 6 form a gap. After the feed enters this gap, it is crushed by the rotating auxiliary roller 15, thus crushing agglomerated feed and preventing agglomeration from affecting subsequent screening accuracy. The crushed feed enters screening chamber 1, and after initial screening by screen 13, small particles are discharged through feed pipe 9 and then guided into vibrating drum 2. Vibrating screen 3; The vibrating motor mounted on the side of the vibrating screen 3 starts, driving the screen 10 installed on the inner wall to vibrate, realizing secondary fine screening. After opening the sealing plate 4, the residual particles can be automatically discharged from the feed port along the inclined surface by utilizing the inclined angle of the screen 10, without the need for manual cleaning. The motor 20 drives the auxiliary roller 15 through bevel gear 18 and bevel gear 29 to crush the lumpy feed, solve the problem of incomplete screening caused by lumps, and improve the uniformity of feed particles. The inclined setting of the screen 10, together with the sealing plate 4, realizes the automatic discharge of residual particles, reduces the intensity of manual labor, and the bolted sealing plate 4 is easy to maintain.

[0023] The usage and working principle of this device are as follows: First, all electrical components mentioned in this application are externally connected to a power supply and control switch. Chicken feed to be processed is fed into hopper 6, allowing it to enter the gap formed by auxiliary roller 15 and the inner wall of hopper 6. Motor 20 drives bevel gear 2 19 to rotate, which in turn drives bevel gear 1 18 and auxiliary roller 15 to rotate. Auxiliary roller 15 crushes any clumps of feed. The crushed feed enters screening chamber 1 and falls onto screen 2 13. A vibrating motor installed on one side of screening chamber 1 assists in screening the feed. Smaller particles are discharged through discharge pipe 2 9 and enter vibrating screen 3 through extension cylinder 2. The vibrating motor installed on one side of vibrating screen 3 starts, vibrating the feed above screen 1 10. The particles are screened, and smaller particles are discharged from the bottom of the vibrating screen 3, while larger particles remain on the top of the screen 10. The screen 10 is inclined. By opening the sealing plate 4, the particles remaining on the top of the screen 10 can be discharged. The synchronous belt assembly 11 includes two synchronous pulleys, a tensioning pulley, and a synchronous belt. During the initial screening, larger particles or impurities inside the feed remain on the screen 2 13. The motor 12 drives one of the synchronous pulleys to rotate, and the other synchronous pulley rotates under the drive of the synchronous belt. At this time, the two lead screws 17 can rotate synchronously, driving the scraper 14 to slide along the sealing cover 7. The scraper 14 scrapes off the material remaining on the screen 2 13, allowing the material to enter the feed pipe 8 and be discharged from the bottom of the feed pipe 8.
