The screen 9 is conical, and the outer height of the screen 9 is higher than the inner bottom wall height of the discharge port 10. The flour enters the interior of the topmost screening cylinder 4, and the flour is initially screened through the screen 9 with the largest mesh number. The flour with larger particle size remains on the top of the screen 9 and is shaken off to the discharge port 10 under the action of the vibration motor 2 and the conical screen 9 and enters the corresponding collection bag for collection. The falling flour is screened again through the lower screen 9, so that the flour is screened into multiple groups according to the particle size and enters the corresponding collection bag through the discharge port 10. After screening, the fine flour enters the corresponding collection bag through the finished product outlet 8.

[0029] In order to realize the detachable connection between the screening drums 4 and between the screening drum 4 and the fixed drum 3, a connecting assembly is also included, which is used to connect the screening drums 4 or between the screening drum 4 and the fixed drum 3. The connecting assembly includes an annular limiting sleeve 101 and a locking piece. The ends of the screening drum 4 and the fixed drum 3 are fixedly connected with a convex ring 102. The annular limiting sleeve 101 is an open structure, which is used to wrap and limit the two adjacent convex rings 102. The locking piece is used to lock the annular limiting sleeve 101 so that it is tightly attached to the convex ring 102. The locking piece includes a locking screw 201 and a locking plate 202.

[0030] The cleaning shaft 5 is rotatably arranged on the screen 9. A cleaning pad 11 is connected to the outside of the cleaning shaft 5 for cleaning the surface of the screen 9. A rotating plate is fixedly connected to the outside of the cleaning shaft 5, and the cleaning pad 11 is fixedly connected to the rotating plate. The cleaning pad 11 is made of an elastic material, such as plastic or rubber. A plurality of through holes are formed at the bottom of the cleaning pad 11. Adjacent cleaning shafts 5 are coaxially connected by a connector. The connector includes a half clutch 301. The half clutch 301 is slidably connected to the cleaning shaft 5. A sliding rod 302 is fixedly connected to the half clutch 301. A sliding groove matching the sliding rod 302 is formed on the cleaning shaft 5. A compression spring 303 is connected between the half clutch 301 and the cleaning shaft 5. The half clutch 301 below the upper cleaning shaft 5 meshes with the half clutch 301 above the lower cleaning shaft 5. A motor 304 is installed inside the fixed cylinder 3. The output end of the motor 304 is connected to the half clutch 301 through a telescopic rod and a compression spring 303. Each half clutch 301 can be meshed. When the screening cylinder 4 is installed on the fixed cylinder 3 and when a plurality of screening cylinders 4 are connected, the half clutches 301 are first meshed, and under the action of the compression spring 303, the half clutches 301 are pressed together, realizing the connection between adjacent cleaning shafts 5 and the connection between the cleaning shaft 5 and the output shaft of the motor 304. The motor 304 drives a plurality of cleaning shafts 5 to rotate synchronously. The cleaning shaft 5 drives the cleaning pad 11 to rotate around the screen 9. The inclination angle of the cleaning pad 11 is adapted to the screen 9 and contacts the top of the screen 9. During the rotation of the cleaning pad 11, the surface of the screen 9 is cleaned, assisting in cleaning the flour at the edge of the screen 9 to the discharge port 10 for discharge, and at the same time reducing the accumulation of flour on the surface of the screen 9, thereby reducing the blockage of the screen by flour. Through the arrangement of the through holes, the flour can pass through the cleaning pad 11, avoiding the accumulation of flour between the cleaning pad 11 and the screen 9.

[0031] The knocking shaft 6 is rotatably arranged inside the screening drum 4, and the knocking shaft 6 is transmission-connected to the cleaning shaft 5. The cleaning shaft 5 can drive the knocking shaft 6 to rotate. The outside of the knocking shaft 6 is connected with a knocking block 12 for knocking the screen 9 through an elastic rod. In order to realize the transmission connection between the knocking shaft 6 and the cleaning shaft 5, the outside of the cleaning shaft 5 is fixedly sleeved with a driving bevel gear 13, and the end of the cleaning shaft 5 is coaxially fixedly connected with a driven bevel gear 14.

The driving bevel gear 13 and the driven bevel gear 14 are both located inside the protective cover 15. The cleaning shaft 5 and the knocking shaft 6 They are all rotatably connected to the protective cover 15. When the motor 304 drives the cleaning shaft 5 and the cleaning pad 11 to rotate to clean the screen 9, the driven bevel gear 13 can drive the driven bevel gear 14 and the knocking shaft 6 to rotate. The knocking shaft 6 is horizontally arranged below the screen 9. The knocking shaft 6 drives the knocking block 12 to rotate. When the knocking block 12 rises to contact with the screen 9, it can knock on the screen 9. The length of the elastic rod is slightly longer than the distance between the knocking shaft 6 and the screen 9, thereby ensuring that the knocking block 12 is in full contact with the screen 9. The elastic rod is bent to adapt to the obstruction of the screen 9 to the knocking block 12, so that the knocking block 12 can continue to rotate after knocking.

[0032] In order to reduce the adhesion of flour on the screen 9, a drying mechanism is also included. The drying mechanism is used to dry the flour inside the fixed cylinder 3 and the screening cylinder 4. The drying mechanism includes a heating bin 401 and a hot air pipe 402.

The heater 403 is energized to generate heat to heat the air in the heating bin 401, and the hot air is blown to the feed cover 404 through the hot air pipe 402 and sent into the interior of the screening cylinder 4, forming a high-speed airflow at the feed port, and the pressure decreases as the flow rate increases, thereby assisting the entry of the flour to be screened from the outside. At the same time, the hot air is blown to the surface of the screen 9, assisting the falling of the flour on the screen 9, thereby improving the screening efficiency. At the same time, the heat of the hot air and the heat transferred to the fixed cylinder 3 by the heating bin 401 heat and dry the flour, thereby reducing the adhesion of the flour caused by moisture.

[0033] The working principle or use process of the high-efficiency vibrating screen for flour processing is as follows: Select a sieve mesh 9 with appropriate mesh number and quantity according to the needs of flour screening. Arrange the screening cylinders 4 in sequence according to the mesh number of the sieve mesh 9. Connect multiple screening cylinders 4, as well as the screening cylinder 4 and the fixed cylinder 3, through the annular limiting sleeve 101. Then install the top cover above the uppermost screening cylinder 4, and dock the half clutch 301 during the installation process; Feed the flour into the interior of the screening cylinder 4 through the feed port. The flour falls onto the uppermost sieve mesh 9. Turn on the vibration motor 2 to drive the fixed cylinder 3 and the screening cylinder 4 to vibrate, thereby driving the sieve mesh 9 to vibrate. The flour with a particle size smaller than that of the sieve mesh 9 falls, and the flour with a particle size larger than that of the sieve mesh 9 remains above the sieve mesh 9 and is shaken off along the inclined surface of the sieve mesh 9 to the discharge port 10 for collection. The flour is subjected to multi-stage screening through multiple sieve meshes 9, and the screened fine flour is discharged through the finished product port 8 at the bottom for collection; During the screening process, the motor 304 drives the cleaning shaft 5 to rotate. The cleaning shaft 5 drives the cleaning pad 11 to clean the surface of the sieve mesh 9. At the same time, the cleaning shaft 5 drives the driving bevel gear 13 to rotate. The driving bevel gear 13 drives the driven bevel gear 14 and the knocking shaft 6 to rotate. The knocking shaft 6 drives the knocking block 12 to knock on the sieve mesh 9, shaking off the flour in the sieve holes of the sieve mesh 9 and reducing the blockage of the sieve mesh 9 caused by the flour.
