[0002] The multi-functional cleaning and screening device for corn feed processing is a core piece of equipment used in the corn feed production and processing flow. It integrates multiple functions such as cleaning and screening. Utilizing mechanical, pneumatic, and other technologies, this device effectively removes impurities from corn raw materials, such as stones, metal objects, and straw fragments. Simultaneously, it can precisely grade and screen corn kernels according to different feed production needs, screening them into materials that meet specific particle size specifications. This provides high-quality, pure raw materials for subsequent feed processing steps such as crushing and mixing, greatly improving the efficiency and quality of corn feed production, ensuring the quality stability and safety of the finished feed product. It is widely used in modern feed processing plants, feed production workshops in livestock farms, and other similar locations.

[0003] In traditional corn feed processing screening equipment, the crushed corn falls directly onto a screen plate for screening. When the screen plate becomes clogged, the operator must first stop the equipment, then open the processing box, remove the screen plate for cleaning.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1 , Figure 2 This utility model provides an embodiment of a multifunctional cleaning and screening device for corn feed processing, including a processing box 1. Two support plates are fixedly connected to the bottom of the processing box 1 to support the entire device, ensuring its stability during operation and preventing shaking from affecting the processing effect of the corn feed. A feed inlet 3 is provided at the top of the processing box 1, serving as a channel for corn to enter the processing box 1, facilitating the operator to feed corn into the equipment for processing. A collection box 2 is movably connected to the left side of the processing box 1, used to receive the corn feed after screening by the sieve plate 15, facilitating subsequent collection and processing. A handle is fixedly connected to the left side of the collection box 2, allowing the operator to easily pull the collection box 2 out of or push it into the processing box 1, making operation convenient. The top of the collection box 2 is open, allowing the screened corn feed to fall smoothly into the collection box 2.

[0029] Reference Figure 3 , Figure 4A motor 4 is fixedly mounted on the front of the processing box 1. The output shaft of the motor 4 is fixedly connected to a rotating rod A. The rotating rod A transmits power from the motor 4, driving the drive gear 8 and the crushing roller 12 to rotate. The end of the rotating rod A is fixedly connected to the drive gear 8 through the inner wall of the processing box 1 via a bearing A. The bearing A ensures stable rotation of the rotating rod A and reduces friction. The drive gear 8 transmits the power of the rotating rod A to the driven gear 9, enabling the two crushing rollers 12 to rotate in opposite directions. A rotating rod B is fixedly connected to the inner wall of the processing box 1 via a bearing B. The bearing B ensures that the rotating rod B can rotate flexibly, working in conjunction with the rotating rod A to drive the crushing roller 12. Crushing rollers 12 are fixedly fitted onto the surface of rotating rod B. The two crushing rollers 12 cooperate with each other and crush the corn into feed by rotating in opposite directions. The crushing rollers 12 are configured to cooperate with each other. A driven gear 9 is fixedly fitted onto the surface of rotating rod B. The driven gear 9 meshes with the driving gear 8 and receives the power transmitted by the driving gear 8 to drive rotating rod B and crushing rollers 12 to rotate. The driving gear 8 meshes with the adjacent side of the driven gear 9. A cleaning component and a replacement component are provided below the processing box 1. The cleaning component is used to clean the blocked screen plate 15. The replacement component allows the unblocked part of the screen plate 15 to be used, ensuring the continuity of screening work.

[0030] Reference Figure 3 , Figure 4 , Figure 5The replacement component includes a threaded rod A6, which converts rotational motion into linear motion of the screen plate 15, thereby changing the position of the screen plate 15. A strip plate 24 is movably connected to the left side of the processing box 1. One end of the threaded rod A6 is threaded through the left side of the strip plate 24 and extends into the processing box 1. The top of the strip plate 24 is fixedly connected to an extension plate, which is bolted to the left side of the processing box 1. Simply removing the bolt from the extension plate releases the locking of the strip plate 24. When there are still residues after screening, it is convenient to remove the strip plate 24 and the screen plate 15 from the processing box 1 for cleaning. One end of the threaded rod A6 is rotatably connected to the screen plate 15 via a bearing C. C ensures that the screen plate 15 does not rotate when moving with the threaded rod A6, thus guaranteeing stable movement of the screen plate 15. Limiting blocks 20 are fixedly connected to both sides of the screen plate 15. The limiting blocks 20 cooperate with the limiting grooves 19 to restrict the movement direction of the screen plate 15, allowing it to slide horizontally within the processing box 1. Limiting grooves 19 are respectively opened on the inner walls of both sides of the processing box 1. The two sides of the screen plate 15 are slidably connected to the inner walls of the limiting grooves 19 through the limiting blocks 20. A partition 16 is fixedly connected to the middle of the screen plate 15, dividing the screen plate 15 into two parts that can be used alternately to improve screening efficiency. When one side is blocked, the other side can be switched to the working position. A knob A14 is fixedly connected to the other end of the threaded rod A6, allowing the operator to manually rotate the threaded rod A6 to adjust the position of the screen plate 15.

[0031] Reference Figure 3 , Figure 4 , Figure 6The cleaning assembly includes a movable groove that provides space for the lifting plate 10 to move up and down, thus cleaning the screen plate 15. The lifting plate 10 is movably connected to the inner wall of the movable groove. As the lifting plate 10 moves up and down within the groove, it drives the top column 11 to clean the screen plate 15. The bottom of the lifting plate 10 is fixedly connected to the top column 11, which engages with the screen holes of the screen plate 15. By moving downwards, the top column pushes out the corn clogging the screen holes, thus cleaning the screen plate 15. A fixing plate 5 is fixedly connected to the front of the processing box 1. The fixing plate 5 is used to fix the threaded rod B13, ensuring its rotational stability. The top of the fixing plate 5... A threaded rod B13 is rotatably connected via bearing C, allowing the threaded rod B13 to rotate flexibly. A knob B is fixedly connected to the top of the threaded rod B13, allowing the operator to manually rotate the threaded rod B13. A threaded sleeve 7 is threadedly connected to the surface of the threaded rod B13. When the threaded rod B13 rotates, the threaded sleeve 7 moves up and down along the threaded rod B13, driving the lifting plate 10 to move. A connecting plate 18 is fixedly connected to the back of the threaded sleeve 7, transmitting the movement of the threaded sleeve 7 to the lifting plate 10, enabling the lifting plate 10 to move synchronously with the threaded sleeve 7. The back of the connecting plate 18 is fixedly connected to the front of the lifting plate 10.

[0032] Reference Figure 3 , Figure 5 , Figure 6 The size of the top column 11 is equal to the number of sieve holes opened on the sieve plate 15. The top column 11 and the sieve holes are longitudinally aligned and the size of the top column 11 and the sieve holes are matched. This design ensures that the top column 11 can be accurately inserted into the sieve hole to push out the blockage and achieve efficient cleaning. The inner wall of the movable groove is provided with an arc-shaped sliding groove 21. The arc-shaped sliding groove 21 cooperates with the ball bearing 22 to guide the lifting plate 10 to move up and down smoothly, while limiting its movement trajectory. The back of the lifting plate 10 is fixedly connected with the ball bearing 22. The ball bearing 22 is slidably connected to the inner wall of the arc-shaped sliding groove 21 to reduce the friction when the lifting plate 10 moves and make the lifting process smoother. The front of the processing box 1 is provided with a sliding hole 17. The sliding hole 17 provides a sliding track for the connecting plate 18 to ensure the stability when the connecting plate 18 drives the lifting plate 10 to move. Both sides of the connecting plate 18 are slidably connected to the inner wall of the sliding hole 17.

[0033] Working Principle: Before use, place the device on a stable surface, with two support plates ensuring stable support. In use, first start the motor 4. The output shaft of the motor 4 drives the rotating rod A to rotate, which in turn drives the drive gear 8, which is fixedly mounted on its surface, to rotate synchronously. Since the drive gear 8 and the driven gear 9 mesh on adjacent sides, the rotation of the drive gear 8 drives the driven gear 9 to rotate, thus causing the two crushing rollers 12, respectively fixedly mounted on the surfaces of rotating rods A and B, to rotate in opposite directions. At this time, corn is fed into the processing box 1 through the feed inlet 3 at the top. After entering the processing box 1, the corn passes through the two opposing rotating crushing rollers 12, where they are crushed through their interaction. The crushed corn feed falls onto the screen plate 15.

[0034] A partition 16 fixedly connected to the middle of the sieve plate 15 divides the sieve plate 15 into left and right parts, allowing feed to be screened using one half of the sieve plate 15. If one half of the sieve plate 15 becomes clogged during screening, it can be cleaned. First, rotate the two knobs B in sequence. Knob B drives the threaded rod B13 fixedly connected to it to rotate. Since the threaded rod B13 has a threaded sleeve 7 threadedly connected to its surface, the threaded sleeve 7 moves upward along the threaded rod B13 when it rotates. The threaded sleeve 7 drives the connecting plate 18 fixedly connected to its back to slide upward along the inner wall of the sliding hole 17 on the front of the processing box 1. The connecting plate 18 then drives the lifting plate 10 movably connected to the inner wall of the movable groove and the top column 11 fixedly connected to the bottom of the lifting plate 10 to move upward. During the upward movement of the lifting plate 10, the ball bearings 22 fixedly connected to its back slide along the arc-shaped groove 21 on the inner wall of the movable groove, ensuring the stability of the lifting plate 10's movement.

[0035] After completing the above operations, rotate knob A14. Knob A14 drives the threaded rod A6, which is fixedly connected to it, to rotate. The threaded rod A6 passes through the left side of the strip plate 24 and moves along the inner wall of the strip plate 24. The limiting blocks 20, which are fixedly connected to both sides of the screen plate 15, slide along the inner wall of the limiting grooves 19 opened on both sides of the processing box 1, so that the screen plate 15 moves as a whole. When the unblocked half of the screen plate 15 moves to below the two crushing rollers 12, the blocked half of the screen plate 15 moves to below the lifting plate 10 and the top column 11. At this time, reverse knob B, which drives the threaded rod B13 to reverse, so that the threaded sleeve 7, connecting plate 18, lifting plate 10 and top column 11 move downward. The top column 11 enters the screen hole opened on the screen plate 15. Since the size of the top column 11 is equal to the number of screen holes opened on the screen plate 15, longitudinally aligned and matched in size, the corn blocked in the screen hole is pushed downward and falls out of the screen hole, thus completing the cleaning work of the screen plate 15.

[0036] During the entire process, if it is necessary to collect the sieved corn feed, the handle on the left side of the collection box 2 can be pulled to remove the collection box 2 from the left side of the processing box 1 and collect the corn feed in the collection box 2. Afterwards, the bolts can be removed from the extension plate to unlock the strip plate 24. When there is still residue after screening by the screen plate 15, it is convenient to remove the strip plate 24 and the screen plate 15 from the inside of the processing box 1 for cleaning.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
