When flour raw materials need to be cleaned and screened, the material is first put into the machine body from the feeding seat, then water is injected into the machine body, the power is turned on, and the switch is turned on. The first motor starts to work, driving the first threaded rod to rotate, which in turn drives the first rotating rod to rotate synchronously. Under the action of the thread, the first screw sleeve moves, driving the second rotating rod to move synchronously. At the same time, the second motor starts to work, driving the second rotating rod to rotate synchronously, which in turn drives the stirring blade to rotate synchronously. The material is separated by the partition holes, increasing the contact area between the material and the water flow, and improving the cleaning effect. Then, the partition plate is pulled out of the machine body, and the material is filtered and screened through the screening holes opened inside the screening plate. At the same time, the first threaded rod drives the third rotating rod to rotate synchronously, which in turn drives the second threaded rod to rotate. Under the action of the thread, the second screw sleeve moves synchronously, realizing the reciprocating motion of the screening plate, which better screens the material. Through this design, when cleaning flour processing raw materials, the moving stirring can increase the contact area between the raw materials and the cleaning water flow, improving the cleaning effect and the practicality of the device.

[0015] 2. The raw material cleaning and screening device and method for flour processing are equipped with a stable moving structure.

When the device needs to be placed stably, the support rod is pulled downwards to make the support block contact the ground. The limiting rod is then inserted into the second limiting hole to complete the stable support when the device is placed. At the same time as the support rod moves, the second limiting block moves synchronously inside the second limiting groove to limit the support rod, thereby improving the stability of the device. The limiting bolts can be used to easily disassemble the support rod and the connecting block, making it convenient to replace the connecting block and the support block. Through this design, the device can be moved easily and can be stably supported when placed in operation, improving the practicality and convenience of the device. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-6 One embodiment provided by the present invention: A raw material cleaning and screening device and method for flour processing includes: a machine body 1, a first motor 21, a second motor 22, casters 23, a feed seat 24, and a discharge seat 25. The machine body 1 has a first motor 21 fixedly connected to the side wall of the machine body 1, a second motor 22 installed inside the machine body 1, a universal wheel 23 fixedly connected to the bottom of the machine body 1, a feed seat 24 fixedly connected to the air vent of the machine body 1, and a discharge seat 25 fixedly connected to the bottom of the machine body 1. Cleaning structure 3 includes a first threaded rod 32, which is fixedly connected to the output shaft of a first motor 21. A first rotating rod 31 is fixedly connected to the end of the first threaded rod 32 away from the first motor 21. A first threaded sleeve 33 is threadedly connected to the surface of the first rotating rod 31. A second rotating rod 34 is located at the bottom of the first threaded sleeve 33. A second motor 22 is fixedly connected to the upper end of the first threaded sleeve 33. The output shaft of the second motor 22 is fixedly connected to the second rotating rod 34. A stirring blade 35 is fixedly connected to the side wall of the first threaded sleeve 33. A partition hole 36 is provided inside the stirring blade 35. The machine body... An internal partition 43 is provided. A third rotating rod 37 is connected to the surface of the first threaded rod 32 via teeth. A second threaded rod 38 is fixedly connected to the bottom end of the third rotating rod 37. A second threaded sleeve 39 is connected to the surface of the second threaded rod 38 via threads. A screening plate 41 is fixedly connected to the side wall of the second threaded sleeve 39. Screening holes 42 are opened inside the screening plate 41. Through this design, the rotation of the first threaded rod 32 drives the third rotating rod 37 to rotate synchronously. Then, the second threaded rod 38 rotates, and under the action of the threads, it drives the second threaded sleeve 39 to move synchronously, and finally drives the screening plate 41 to move. The forward and reverse rotation of the first motor 21 drives the screening plate 41 to reciprocate, thereby automatically filtering the flour raw materials. A first limiting block 46 is fixedly connected to the side wall of the third rotating rod 37. The first limiting block 46 is inserted into the first limiting groove 47, which is located inside the machine body 1. This design ensures that the first limiting block 46 rotates synchronously within the first limiting groove 47 while the third rotating rod 37 rotates, thus limiting the movement of the third rotating rod 37 and improving the stability of the device. A slider 48 is fixedly connected to the side wall of the second screw sleeve 39. The slider 48 is inserted into the slide groove 49. 9 is located inside the body 1. Through this design, under the action of slider 48 and slide groove 49, when the second threaded rod 38 rotates, the second threaded sleeve 39 is prevented from rotating synchronously with the second threaded rod 38. A third limiting block 59 is fixedly connected to the bottom side wall of the second threaded rod 38. The third limiting block 59 is inserted into the third limiting groove 61, which is located inside the body 1. Through this design, while the second threaded rod 38 rotates, the third limiting block 59 rotates synchronously inside the third limiting groove 61, thereby limiting the second threaded rod 38 and improving the stability of the device. The stable moving structure 5 includes a support rod 51, which is inserted inside the body 1. The bottom end of the support rod 51 is inserted into the connecting block 52, and the bottom end of the connecting block 52 is fixedly connected to the support block 53. A first limiting hole 54 and a second limiting hole 55 are provided inside the body 1. The support rod 51 has a limiting hole. This design allows the device to be easily moved. When placed, pulling the support rod 51 downwards causes the support block 53 to contact the ground. Then, the limiting rod is inserted into the second limiting hole 55, providing stable support for the device during placement. A second limiting block 56 is fixedly connected to the wall and inserted into a second limiting groove 57. The second limiting groove 57 is opened inside the body 1. With this design, while the support rod 51 moves, the second limiting block 56 moves synchronously inside the second limiting groove 57, thereby limiting the support rod 51 and improving the stability of the device. A limiting bolt 58 is provided inside the support rod 51 and is located inside the connecting block 52. With this design, the support rod 51 and the connecting block 52 can be easily removed using the limiting bolt 58, making it convenient to replace the connecting block 52 and the support block 53.

[0020] Working principle: When it is necessary to clean and screen the flour raw materials, the material is first put into the machine body 1 through the feed seat 24. Then, water is injected into the machine body 1, the power is turned on, and the switch is turned on. The first motor 21 starts to work, driving the first threaded rod 32 to rotate, which in turn drives the first rotating rod 31 to rotate synchronously. Under the action of the thread, the first threaded sleeve 33 moves, driving the second rotating rod 34 to move synchronously. At the same time, the second motor 22 starts to work, driving the second rotating rod 34 to rotate synchronously, which in turn drives the stirring blade 35 to rotate synchronously. The material is separated by the partition hole 36, increasing the contact area between the material and the water flow and improving the cleaning effect. Then, the partition plate 43 is pulled out of the machine body 1, and the material is filtered and screened through the screening hole 42 opened in the screening plate 41. At the same time, the first threaded rod 32 drives the third rotating rod 37 to rotate synchronously, which in turn drives the second threaded rod 38 to rotate. Under the action of the thread, the second threaded sleeve 39 moves synchronously, realizing the reciprocating motion of the screening plate 41, which better screens the material.

[0021] When the device needs to be moved, the casters 23 can be used to move the device easily. When the device needs to be placed stably, the support rod 51 is pulled down to make the support block 53 contact the ground. The limiting rod is then inserted into the second limiting hole 55 to complete the stable support when the device is placed. At the same time as the support rod 51 moves, the second limiting block 56 moves synchronously in the second limiting groove 57 to limit the support rod 51 and improve the stability of the device. The limiting bolt 58 can be used to easily remove the support rod 51 and the connecting block 52, making it easy to replace the connecting block 52 and the support block 53. The operation is now complete.

[0022] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
