Description

Technical Field

[0001] This utility model relates to the field of feed ingredient screening technology, specifically a device for screening natural plant feed ingredients. Background Technology

[0002] Natural plant-based feed ingredients can include legumes (such as alfalfa and soybeans), corn, etc. During feed production, larger ingredients need to be screened out. A feed screening device for feed production, published in CN221983020U, uses a roller in conjunction with a fixed shell, filter holes, a second fixed shell, a second motor, a first rotating shaft, a first gear ring, and a second gear ring. This allows the device to push the feed through the filter holes to prevent accumulation, significantly improving the screening efficiency. However, the filter holes are easily clogged by the feed. This device lacks a structure to remove the blockage, leading to fewer usable filter holes and affecting the efficiency of feed screening. Utility Model Content

[0010] This utility model provides a natural plant feed raw material screening device, which has the following beneficial effects: 1. This natural plant feed raw material screening device, equipped with a hose, a spray hood, and a rotating cylinder, operates by using a servo motor to drive a drive gear when cleaning blockages inside the spray nozzles of the perforated structure. The drive gear then drives a drive gear to rotate the rotating cylinder, which in turn rotates a reflector block. When a photoelectric detector detects that the reflector block has rotated to the cleaning position, the servo motor stops. Then, the extension end of the second electric telescopic rod pushes the spray hood downwards, bringing its bottom into contact with the surface of the rotating cylinder. A pressurized air pump then draws in air and discharges pressurized gas into the hose and spray hood, spraying it through the nozzle at the bottom of the spray hood into the spray nozzle to clean out the blockages inside the nozzle, thus ensuring efficient screening of the raw materials.

The feed raw materials are poured into the storage box through the feed hopper. Then, the telescopic end of the first electric telescopic rod pushes the pusher block and the baffle to move, so that the pusher block pushes the raw materials in the storage box towards the feed valve. Then, the telescopic end of the first electric telescopic rod drives the pusher block and the baffle to reset and move. This process is repeated to continuously push the raw materials in the storage box towards the feed valve, preventing the raw materials in the storage box from falling behind the pusher block and causing the pusher block to be obstructed when it moves.

A drive gear 18 is fixedly sleeved on the output end of the servo motor 17. An active gear 19 that meshes with the drive gear 18 is fixedly sleeved on the outside of the rotating cylinder 9. Several sets of hole structures 10 are opened on the surface of the rotating cylinder 9, and each set of hole structures 10 is composed of several nozzles 15. The nozzles 15 are all opened on the outside of the rotating cylinder 9 and located on the left side of the filter hole 16. A controller is fixedly connected to the rear of the bottom box 1, and a feed hopper 3 is fixedly connected to the top of the storage box 2.

[0016] Two second electric telescopic rods 24 are fixedly connected to the bottom of the storage box 2. The telescopic ends of the two second electric telescopic rods 24 are fixedly connected to the spray hood 14. The bottom of the spray hood 14 has a nozzle. A pressurized air pump 22 is fixedly connected to one side of the storage box 2. A hose 23 is fixedly connected to the air outlet of the pressurized air pump 22. One end of the hose 23 is fixedly connected to the air inlet of the spray hood 14. Air is drawn in by the pressurized air pump 22, and then pressurized air is input into the spray hood 14 through the hose 23 and then sprayed out through the nozzle.

[0017] A feed valve 29 is fixedly connected to the bottom of the storage box 2. The bottom end of the feed valve 29 extends into the inside of the first fixed cylinder 7. A discharge valve 26 is fixedly connected to the bottom of the second fixed cylinder 8. The raw material inside the second fixed cylinder 8 is discharged through the discharge valve 26.

[0018] A first electric telescopic rod 4 is fixedly connected to one side of the storage box 2. The telescopic end of the first electric telescopic rod 4 extends into the storage box 2 and is fixedly connected to a push block 5. A baffle 6 is fixedly connected to the top of the push block 5. One end of the baffle 6 extends to the outside of the storage box 2. A pull rope sensor is fixedly connected to one side of the storage box 2, and the pull rope end of the pull rope sensor is fixedly connected to one side of the push block 5. The pull rope sensor is located below the baffle 6. The pull rope sensor detects the moving distance between the push block 5 and the baffle 6. The baffle 6 cooperates with the inner cavity of the storage box 2 to prevent the raw materials inside the storage box 2 from falling behind the push block 5 when the push block 5 moves, thus preventing the push block 5 from being obstructed. The pull rope sensor is a pull rope displacement sensor DSS-M.

[0019] A second motor 27 is fixedly connected to one side of the first fixed cylinder 7. A screw conveyor shaft 13 is rotatably connected to one side of the inner cavity of the first fixed cylinder 7 via a bearing. One end of the screw conveyor shaft 13 is rotatably connected to one side of the inner cavity of the second fixed cylinder 8 via a bearing. The output end of the second motor 27 is connected to one end of the screw conveyor shaft 13 via a coupling. The output end of the second motor 27 drives the screw conveyor shaft 13 to rotate, thereby moving the raw materials inside the first fixed cylinder 7, the rotating cylinder 9, and the second fixed cylinder 8.

[0020] A photoelectric detector 20 is fixedly connected to one side of the inner cavity of the filter hole 16. Several reflective blocks 21 are fixedly connected to the outer side of the rotating cylinder 9, and the positions of the several reflective blocks 21 correspond to the positions of several sets of hole structures 10. A collection drawer 28 is placed inside the bottom box 1. The second fixed cylinder 8 is fixedly connected to one side of the storage box 2 through the fixing frame 25. The device is operated by the controller according to the control program.

[0021] In summary, when using this natural plant feed raw material screening device, the feed raw materials are poured into the storage box 2 through the feed hopper 3. Then, the telescopic end of the first electric telescopic rod 4 pushes the push block 5 and the baffle 6 to move, so that the push block 5 pushes the raw materials inside the storage box 2 to move into the feed valve 29. When the pull rope sensor detects that the push block 5 has moved a specified distance, the telescopic end of the first electric telescopic rod 4 drives the push block 5 and the baffle 6 to reset and move. This process is repeated to continuously push the raw materials inside the storage box 2 into the feed valve 29. After the raw material enters the first fixed cylinder 7 through the feed valve 29, the output end of the second motor 27 drives the screw conveyor shaft 13 to rotate, so that the screw conveyor shaft 13 pushes the raw material inside the first fixed cylinder 7 towards the rotating cylinder 9 and the second fixed cylinder 8. Raw materials of the appropriate size fall out through the nozzle 15 on the hole structure 10 into the collection tray 28, while larger raw materials are discharged through the discharge valve 26 into the storage container placed below. When it is necessary to clean the blockage inside the nozzle 15 on the hole structure 10, the output end of the servo motor 17 drives the drive gear 18 to rotate, which in turn drives the drive gear 19 to rotate the rotating cylinder 9. This causes the rotating cylinder 9 to rotate the reflector block 21. When the photoelectric detector 20 detects that the reflector block 21 has rotated to the cleaning position, the servo motor 17 stops working. Then, the extension end of the second electric telescopic rod 24 pushes the spray cover 14 down, so that the bottom of the spray cover 14 contacts the surface of the rotating cylinder 9. Next, the pressurized air pump 22 draws in air and then discharges the pressurized gas into the hose 23 and the inside of the spray cover 14. The gas is then sprayed into the nozzle 15 through the nozzle at the bottom of the spray cover 14, cleaning out the blockage inside the nozzle 15. The blockage is then transported to the discharge valve 26 through the screw conveyor shaft 13 and discharged through the discharge valve 26. The blockage inside the other nozzles 15 can fall into the collection tray 28, which has already been used to pick up the raw materials of the correct size.
