The first screen mesh 29, the second screen mesh 30, and the third screen mesh 31 are all made of manganese steel.

[0025] Specifically, a vibrator fixing plate 9 is fixedly connected to the upper end face of the screening bin 24, and a vibrator 10 is fixedly connected to the upper end face of the vibrator fixing plate 9.

[0026] In this embodiment, the vibrator fixing plate 9 is fixed to the screening bin 24 by bolts. There are two vibrators 10, and the vibrators 10 are fixed to the vibrator fixing plate 9 by welding.

[0027] Specifically, a rear support seat 20 and a front support seat 28 are fixedly installed on the upper end face of the screening box fixing seat 19. A vibration spring 21 is fixedly connected to the upper end faces of the rear support seat 20 and the front support seat 28. The upper end face of the vibration spring 21 is fixedly connected to a vibration spring fixing plate 23, and the vibration spring fixing plate 23 is fixedly connected to the side end face of the screening bin 24.

[0028] In this embodiment, there are two screening box fixing seats 19, which are made of I-beam material. The rear support seat 20, the front support seat 28, and the screening box fixing seat 19 are connected by welding. The height of the rear support seat 20 is higher than that of the front support seat 28, making the screening bin 24 at a certain inclination angle. There are two groups of the rear support seat 20 and the front support seat 28 arranged symmetrically. The vibration spring fixing plate 23 is welded to the side end face of the screening bin 24, and a reinforcing rib is provided at the welding position to prevent damage to the screening bin 24 during operation. There are four vibration spring fixing plates 23 arranged symmetrically.

[0029] Specifically, a bin fixing rod 4 is fixedly connected to the circumference of the bin 5. The lower end face of the bin fixing rod 4 is fixedly connected to a bin support rod 1. Feeding auger support rods 2 are fixedly installed on the inner end faces on both sides of the two bin support rods 1 close to the screening structure 13. A feeding auger fixing block 3 is fixedly installed on the upper end face of the feeding auger support rod 2, and the upper end face of the feeding auger fixing block 3 is fixedly connected to the feeding auger 6.

[0030] In this embodiment, four silo fixing rods 4 are provided and fixed by welding. Eight silo support rods 1 are provided, and two silo support rods 1 are symmetrically arranged on each silo fixing rod 4.

[0031] Specifically, a feed inlet 8 is fixedly installed on the upper end surface of the screening silo 24, and a material leveling plate 7 is fixedly installed inside the feed inlet 8. The material leveling plate 7 has a structure that is high in the middle and low on both sides.

[0032] In this embodiment, the material leveling plate 7 can be directly placed inside the feed inlet 8. Six through holes are symmetrically arranged on the material leveling plate 7 to achieve the function of leveling the material.

[0033] Specifically, a first discharge port 14 and a second discharge port 15 are fixedly installed on the right end surface of the screening silo 24. A bottom layer material receiving plate 32 is fixedly installed on the lower side end surface of the screening silo 24. A third discharge port 26 is fixedly installed on the lower side of the bottom layer material receiving plate 32. A crushing box 16 is arranged at the lower part of the screening silo 24.

[0034] In this embodiment, the first discharge port 14 discharges large particles such as stones screened out. The second discharge port 15 screens out non - flour processing raw materials. The third discharge port 26 screens out plump flour processing raw materials. The empty opening arranged under the material receiving plate 32 discharges the crushed flour processing raw materials into the crushing box 16.

[0035] The working principle and usage process of the present utility model: The staff turns on the power supply, and the feeding auger 6, the vibrator 10 and the air box 17 start to work. The raw materials in the silo 5 fall into the feeding silo 22 under the action of gravity, enter the feed inlet 8 through the feeding auger 6, and under the action of the material leveling plate 7, the raw materials evenly fall onto the first screen 29. Under the combined action of the vibrator 10 and the vibration spring 21, the screening silo 24 starts to vibrate, thereby driving the first screen 29, the second screen 30 and the third screen 31 to vibrate. After passing through the first screen 29, large particles such as stones and part of the dust are screened out and discharged through the first discharge port 14. Then the other raw materials fall onto the second screen 30. Most of the dust and other wastes will float between the second screen 30 and the first screen 29 and are collected and discharged successively through the upper dust suction port 27, the suction pipe 12 and the dust collection and filtration box 11 under the action of the air box 17. The remaining small - particle wastes are discharged through the second discharge port 15. Then the raw materials fall onto the third screen 31. A small part of the floating dust will pass through the lower dust suction port 27 and the suction pipe 12 and enter the dust collection and filtration box 11 for discharge. Then the plump raw materials are discharged from the screening structure 13 through the third discharge port 26. Finally, the crushed and unplump raw materials fall onto the bottom layer material receiving plate 32 and fall into the crushing box 16 under the action of gravity.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used 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 recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
