TECHNICAL FIELD
[0001] The application relates to the technical field of cattle and sheep feed processing, and more particularly to a multi-stage screening device integrated in a cattle and sheep feed processing flow. BACKGROUND
[0002] Cattle and sheep feed refers to nutrients specially provided for ruminants such as cattle and sheep, aiming to meet the nutritional needs in the processes of growth, maintenance, production (such as milk production and meat production), etc. The selection and use of feed have an important influence on the health, growth performance and breeding benefits of cattle and sheep. When selecting cattle and sheep feed, the particle size grading and impurity cleaning of the crushed raw materials or the finished feed after granulation and cooling need to be performed to ensure the purity and safety of the feed.
[0003] When screening the feed, the drawer type vibrating screen or the drum screen is usually used for screening. However, the drawer type vibrating screen is prone to cause the crushing of puffed feed or granular feed with a crisp surface due to the strong vibration and the collision between materials during screening, thereby increasing the powder content of the finished product. The screen of the drum screen is easy to be blocked by materials with slightly high moisture content or high fiber content, which seriously affects the screening efficiency. Meanwhile, when crops such as corn, wheat and soybeans are harvested as cattle and sheep feed, agricultural machinery such as a combine harvester may be worn, parts may fall off or crack, thereby causing screws, nuts, iron fragments and the like to be mixed into the grains. The feed raw materials may use old, damaged woven bags or containers during transportation. During open-air drying or storage, metal fragments, iron wires and the like on the ground may also be mixed in. Since cattle and sheep are ruminants, they eat fast and chew insufficiently, and are very likely to swallow metal foreign matters together with the feed. After the foreign matters enter the rumen, due to the rhythmic contraction of the heavy reticulum (the second stomach), the sharp metal objects are likely to pierce the stomach wall, causing a series of serious diseases.
[0004] Therefore, the multi-stage screening device integrated in the cattle and sheep feed processing flow is proposed for the above problems. SUMMARY

[0016] The technical effects and advantages of this application are as follows: Compared with existing technologies, this multi-stage screening device integrated into the cattle and sheep feed processing flow utilizes a drum screen, a vibrating screen, and a cleaning mechanism. The drum screen gently separates most of the qualified finished feed pellets while separating obviously oversized particles. The gentle movement of the drum screen ensures that the finished feed pellets are not crushed, and it completes the initial, large-scale grading process. The "qualified" feed after the initial screening by the drum screen is then conveyed to the vibrating screen, where the most uniformly sized and best-looking feed pellets are discharged from the second outlet, while smaller pellets are removed. Particles and powders are sieved through a vibrating screen, ensuring that the final product has extremely high particle size uniformity and purity, with the powder content minimized. At the same time, when the scraper moves in the drum screen, if there are metal foreign objects mixed in the feed, these metal foreign objects may get stuck on the screen holes of the drum screen as it rotates, or they may rotate with the feed in the drum screen. As the scraper moves the connecting frame, the metal foreign objects mixed in the feed and stuck on the screen holes of the drum screen will be firmly attracted by the electromagnetic rod when they pass through the strong magnetic field area, so that the metal foreign objects are adsorbed on the connecting frame, preventing the metal foreign objects from remaining in the feed and causing harm to cattle and sheep.

A first gear 407 is fixedly connected to the surface of the fixed rod 406, and a ring rack 408 is fixedly connected to the surface of the drum screen 3. The first gear 407 and the ring rack 408 cooperate. Starting the first drive motor 401 can drive the reciprocating screw 402 to rotate. The reciprocating screw 402 can drive the first pulley 403 to rotate, so that the first pulley 403 drives the second pulley 405 to rotate through the belt 404. Then, the second pulley 405 drives the first gear 407 on the fixed rod 406 to rotate, so that the first gear 407 drives the drum screen 3 to rotate through the ring rack 408.
[0022] In a preferred embodiment, the connecting mechanism 5 includes an annular sleeve 501, an annular groove 502, ball bearings 503, and an annular block 504. Two sets of annular sleeves 501 are fixedly connected inside the screening machine 1. Annular grooves 502 are formed on the surface of the two sets of annular sleeves 501. Multiple sets of ball bearings 503 are rotatably connected to the inner wall of the annular grooves 502. The ball bearings 503 allow the annular block 504 to rotate in the annular grooves 502. Two sets of annular blocks 504 are fixedly connected to the surface of the drum screen 3. The annular grooves 502 cooperate with the annular blocks 504. The annular sleeves 501 and the annular grooves 502 can limit the annular blocks 504, making the drum screen 3 more stable when rotating.
[0023] In a preferred embodiment, the cleaning mechanism 6 includes a fixed plate 601, a connecting block 602, a scraper 603, a brush 604, a connecting frame 605, an electromagnetic rod 606, a first rack 607, and a control button 608. One end of the fixed plate 601 is fixedly connected to the screening machine 1, and the other end is fixedly connected to the fixed frame 2. The surface of the reciprocating screw 402 is threadedly connected to the connecting block 602, and the surface of the connecting block 602 is fixedly connected to the scraper 603. The surface of the scraper 603 is provided with multiple sets of brushes 604. When the reciprocating screw 402 rotates, the connecting block 602 drives the scraper 603 to move left and right. When the scraper 603 drives the brushes 604 to move in the drum screen 3, the inside of the drum screen 3 can be cleaned. The brushes 604 can clean the screen holes on the inner wall of the drum screen 3, thereby preventing the drum screen 3 from being blocked and affecting the screening effect.
[0024] In a preferred embodiment, the surface of the scraper 603 is provided with a connecting frame 605, and the surface of the connecting frame 605 is provided with multiple sets of electromagnetic rods 606. When the scraper 603 moves in the drum screen 3, if there are metal foreign objects mixed in the feed, these metal foreign objects may be caught on the screen holes of the drum screen 3 or rotate with the feed in the drum screen 3 as the scraper 603 drives the connecting frame 605 to move. When the metal foreign objects mixed in the feed and caught on the screen holes of the drum screen 3 pass through the strong magnetic field area, they will be attracted by the electromagnetic rods 606. 06 firmly attracts and adsorbs the metal foreign object onto the connecting frame 605. The surface of the scraper 603 is fixedly connected to the first rack 607. One end of the first rack 607 is provided with a control button 608. The electromagnetic rod 606 cooperates with the control button 608. The control button 608 can control the opening and closing of the electromagnetic rod 606. When the electromagnetic rod 606 is open, it can attract the metal foreign object. When the electromagnetic rod 606 is closed, the magnetic force on the surface of the electromagnetic rod 606 disappears, and the metal foreign object attracted onto the connecting frame 605 will fall off.
[0025] In a preferred embodiment, the storage mechanism 7 includes a connecting groove 701, a second gear 702, a connecting rod 703, a third gear 704, a second rack 705, a first collection box 706, and a first handle 707. The surface of the fixing frame 2 is provided with the connecting groove 701. The second gear 702 is rotatably connected inside the fixing frame 2. The second gear 702 cooperates with the first rack 607. The surface of the second gear 702 is fixedly connected with the connecting rod 703. One end of the connecting rod 703 is fixedly connected with the third gear 704. When the first rack 607 is inserted into the connecting groove 701, the first rack 607 can drive the second gear 702 to rotate, so that the second gear 702 can drive the third gear 704 to rotate through the connecting rod 703.
[0026] In a preferred embodiment, a third gear 704 is rotatably connected inside the fixing frame 2, and a second rack 705 is meshed with the surface of the third gear 704. A first collection box 706 is fixedly connected to the surface of the second rack 705, and the first collection box 706 is slidably connected to the inner wall of the fixing frame 2. When the third gear 704 rotates, it can drive the second rack 705 to move, so that the second rack 705 drives the first collection box 706 to move out of the fixing frame 2. A first handle 707 is fixedly connected to one end of the first collection box 706. When the first collection box 706 is full of metal foreign objects, the first collection box 706 can be pulled out of the fixing frame 2 through the first handle 707 for the treatment of metal foreign objects.
[0027] In a preferred embodiment, the vibration mechanism 9 includes a limiting groove 901, a limiting block 902, a baffle 903, a first spring 904, a first rotating rod 905, a first protrusion 906, a fixing block 907, a second drive motor 908, a second rotating rod 909, and a second protrusion 910. The screening machine 1 has two sets of limiting grooves 901 inside. The inner walls of the two sets of limiting grooves 901 are slidably connected to the limiting block 902. A vibrating screen 8 is fixedly connected to one side of the limiting block 902. Two sets of baffles 903 are fixedly connected to the surface of the vibrating screen 8, and two sets of baffles 903 are fixedly connected to one end of the vibrating screen 8. The first spring 904, one end of two sets of first springs 904 are fixedly connected to the screening machine 1, one end of the vibrating screen 8 is fixedly connected to the first rotating rod 905, the surface of the first rotating rod 905 is rotatably connected to the screening machine 1, the bottom of one end of the vibrating screen 8 is fixedly connected to the first protrusion 906, one side of the screening machine 1 is fixedly connected to the fixed block 907, the inside of the fixed block 907 is fixedly connected to the second drive motor 908, one end of the second drive motor 908 is fixedly connected to the second rotating rod 909, one end of the second rotating rod 909 is rotatably connected to the screening machine 1, the surface of the second rotating rod 909... Two sets of second protrusions 910 are fixedly connected to the surface. The first protrusion 906 cooperates with the second protrusion 910. When most of the qualified finished pellet feed is gently screened by the drum screen 3, while obviously oversized particles (such as unformed lumps) are separated, the "qualified" feed after preliminary screening by the drum screen 3 will be conveyed to the vibrating screen 8. The second drive motor 908 is started, causing the second rotating rod 909 to rotate. When the second rotating rod 909 rotates, it drives the second protrusion 910 to rotate. When the second protrusion 910 rotates, the protrusion at the top pushes the first protrusion 906 to vibrate. As the screen 8 moves upward, one end of the vibrating screen 8 presses against the first spring 904. When the protrusion at the top of the second protrusion 910 passes the first protrusion 906, the pressed first spring 904 resets, and the rear end of the vibrating screen 8 can move up and down, allowing the vibrating screen 8 to vibrate. This process is repeated to achieve the screening effect of the vibrating screen 8, thereby discharging the feed particles with the most uniform size and perfect appearance through the vibrating screen 8 from the second discharge port 12. At the same time, small particles and powder in the feed particles are screened out through the vibrating screen 8 for subsequent recycling.
[0028] In a preferred embodiment, the collecting mechanism 13 includes a groove 1301, a spring groove 1302, a second spring 1303, a locking pin 1304, a second collecting box 1305, a locking pin groove 1306, and a second handle 1307. The surface of the screening machine 1 has a groove 1301. One end of the inner wall of the groove 1301 has a spring groove 1302. The inner wall of the spring groove 1302 has a second spring 1303. One end of the second spring 1303 is fixedly connected to the spring groove 1302, and the other end is fixedly connected to the locking pin 1304. The inner wall of the groove 1301 is slidably connected to the second collecting box 1305. One side of the second collecting box 1305 has a locking pin groove 1306, and the locking pin 1304 mates with the locking pin groove 1306. The second collection box 1305 is fixedly connected to a second handle 1307 at one end. The second handle 1307 allows the second collection box 1305 to be easily pulled out of the screening machine 1 and inserted into the groove 1301. The surface of the second collection box 1305 will compress the spring 1303 and the locking pin 1304. When the second collection box 1305 is in the correct position, the second spring 1303 returns to its original position and pushes the locking pin 1304 into the locking pin groove 1306, so that the second collection box 1305 can be locked in the screening machine 1. When small particles and powder in the feed pellets are screened out by the vibrating screen 8, these small particles and powder will fall into the second collection box 1305 for collection and subsequent unified processing.
[0029] In a preferred embodiment, the top of the screening machine 1 is provided with a feed inlet 10 so that the feed to be screened can be added into the drum screen 3 through the feed inlet 10. One end of the screening machine 1 is provided with a first discharge outlet 11 and a second discharge outlet 12. The drum screen 3 gently screens out most of the qualified finished pellet feed, while separating obviously oversized particles. These oversized particles will be discharged through the first discharge outlet 11. Through the screening of the vibrating screen 8, the feed particles with the most uniform size and the most perfect appearance can be discharged from the second discharge outlet 12.
[0030] The working process of this application is as follows: The feed to be screened is added into the drum screen 3 through the feed inlet 10. Starting the first drive motor 401 can drive the reciprocating screw 402 to rotate. The reciprocating screw 402 can drive the first pulley 403 to rotate, which in turn drives the second pulley 405 to rotate via the belt 404. The second pulley 405 then drives the first gear 407 on the fixed rod 406 to rotate, which in turn drives the drum screen 3 to rotate via the ring rack 408. The rotation of the drum screen 3 can gently screen out most of the qualified finished pellet feed, while separating out obviously oversized particles. These oversized particles will be discharged through the first discharge outlet 11. At the same time, when the reciprocating screw... When rod 402 rotates, connecting block 602 drives scraper 603 to move left and right. Scraper 603 drives brush 604 to move within the drum screen 3, cleaning the interior of the drum screen 3. Brush 604 cleans the screen holes on the inner wall of the drum screen 3, preventing clogging and ensuring proper screening. When scraper 603 moves within the drum screen 3, if there are metal foreign objects mixed in the feed, these objects may become stuck on the screen holes or rotate with the feed. As scraper 603 drives connecting frame 605 to move, metal foreign objects mixed in the feed and stuck on the screen holes are firmly attracted by the electromagnetic rod 606 when passing through a strong magnetic field area, preventing the metal foreign objects from being trapped. Adsorbed on the connecting frame 605, as the connecting block 602 moves the scraper 603, the first rack 607 inserts into the connecting groove 701. The first rack 607 drives the second gear 702 to rotate, which in turn drives the third gear 704 to rotate via the connecting rod 703. The third gear 704 then moves the second rack 705, causing it to move the first collection box 706 out of the fixing frame 2. At this point, the connecting frame 605 is above the first collection box 706. As the first rack 607 moves, the inner wall of the connecting groove 701 presses against the control button 608, turning off the electromagnetic rod 606. The magnetic force on the surface of the electromagnetic rod 606 disappears, and the metal foreign object adsorbed on the connecting frame 605 falls into the groove. In the first collection box 706, after the connecting block 602 moves to its farthest distance on the reciprocating screw 402, the connecting block 602 will start to move in the opposite direction, causing the first rack 607 to move out of the connecting groove 701. The first rack 607 drives the second gear 702 to rotate in the opposite direction, and the third gear 704 rotates in the opposite direction, driving the second rack 705 to move, so that the first collection box 706 is retracted into the fixed frame 2 to avoid affecting the discharge of the drum screen 3. When most of the qualified finished pellet feed is gently screened out by the drum screen 3, while obviously oversized particles (such as unformed lumps) are separated, the "qualified" feed after preliminary screening by the drum screen 3 will be conveyed to the vibrating screen 8, and the second drive motor 908 will be started to rotate the second rotating rod 909.When the second rotating rod 909 rotates, it drives the second protrusion 910 to rotate as well. As the second protrusion 910 rotates, its top protrusion pushes the first protrusion 906, causing the vibrating screen 8 to move upwards. Simultaneously, one end of the vibrating screen 8 compresses the first spring 904. When the top protrusion of the second protrusion 910 passes the first protrusion 906, the compressed first spring 904 returns to its original position, allowing the rear end of the vibrating screen 8 to move up and down, thus enabling it to vibrate. This process is repeated to achieve the screening effect, allowing the most uniformly sized and perfectly shaped feed particles to be discharged from the second discharge port 12. At the same time, smaller particles and powder are separated from the feed particles and fall into the second collection box 1305 for collection and subsequent processing. This is the working principle of a multi-stage screening device integrated into the cattle and sheep feed processing flow.
