A connecting sleeve 13 is rotatably connected to the center of the surface of the first inclined support plate 2. One end of the connecting sleeve 13 passes through the first inclined support plate 2 and is fixedly connected to a screening roller 4. The surface of the screening roller 4 has several filter holes. The top end of the connecting sleeve 13 is rotatably connected to the top of the second inclined support plate 3.

The drive pulley 11 and the outer wall of the driven pulley 15 are connected by a transmission belt 12. A rotating shaft 14 is rotatably connected to the inner wall of the connecting sleeve 13. One end of the rotating shaft 14 penetrates into the interior of the screening drum 4. A second connecting plate 19 is fixedly connected to the end of the rotating shaft 14 that penetrates into the inner wall of the screening drum 4. Pushing vortex blades 8 are fixedly connected to both sides of the second connecting plate 19. The pushing vortex blades 8 are concentrically arranged with the screening drum 4. A second drive motor 17 is fixedly connected to the center of the bottom of the outer side of the first inclined support plate 2. A drive bevel gear 18 is fixedly connected to the output end of the second drive motor 17. A driven bevel gear 16 is fixedly connected to one side of the bottom of the rotating shaft 14. The drive bevel gear 18 and the driven bevel gear 16 are meshed together.
[0023] As an optional technical solution of this utility model, a first connecting plate 5 is fixedly connected to the top of the second inclined support plate 3, and a feeding pipe 6 is fixedly connected to the center of the bottom of the first connecting plate 5. The center of the feeding pipe 6 corresponds to the center of the screening drum 4, and the bottom end of the feeding pipe 6 is located at the bottom of the screening drum 4. The feeding pipe 6 can send the added material to the bottom of the screening drum 4 so that the material can be pushed by the pushing vortex blade 8, which can push the material upward along the screening drum 4, so that the material can be fully screened through the screening drum 4, thereby improving the screening effect.
[0024] As an optional technical solution of this utility model, a discharge hopper 7 is fixedly connected to the top of the outer side of the second inclined support plate 3. The discharge hopper 7 is located at the bottom of the top outlet of the screening drum 4. The width of the discharge hopper 7 is greater than the diameter of the screening drum 4. The discharge hopper 7 is inclined downward so that it can completely receive the material pushed upward by the screening drum 4, so as to guide the material out.
[0025] As an optional technical solution of this utility model, a discharge ramp is fixedly connected to the top surface of the bottom plate 1. The width of the discharge ramp is greater than the diameter of the screening drum 4, and the length of the discharge ramp is greater than the distribution length of the screening drum 4, so that the discharge ramp can receive the material screened off by the screening drum 4 and guide the material to slide to the bottom.

[0027] The raw material screening device for this repair material requires the following steps when in use:
[0028] 1) The material can be fed into the bottom of the screening drum 4 through the feeding pipe 6;
[0029] 2) Then the first drive motor 10 drives the screening drum 4 to rotate. The screening drum 4 can perform rolling screening of raw materials. At the same time, the inclined structure of the screening drum 4 prevents raw materials that are not screened out in time from slipping off.
[0030] 3) The second drive motor 17 drives the rotating shaft 14 to rotate, which in turn drives the pusher vortex blade 8 to rotate. This can gradually push the large particles screened out of the screening drum 4 upward along the inner wall and finally push them out, thus realizing the automatic ejection of the material.
[0031] In summary, the rolling of the screening drum 4 allows for the screening of raw materials. The inclined structure of the screening drum 4 prevents unscreened materials from slipping off. Furthermore, the rotating shaft 14 drives the pusher vortex blades 8 to rotate, gradually pushing large particles screened into the screening drum 4 upwards along the inner wall until they are discharged, achieving automatic material ejection. The feeding pipe 6 delivers material to the bottom of the screening drum 4, where it is pushed upwards by the pusher vortex blades 8, ensuring thorough screening and improving the screening effect.
