[0008] Beneficial effects of the utility model:
[0009] The utility model combines a sand screening mechanism with a stirring mechanism, and the sand can be directly fed into the mixer after being screened. The sand screening process does not affect the stirring work, and the two can be carried out at the same time. After the sand screening mechanism screens a certain amount of sand, the sand can be directly dropped into the stirring mechanism, eliminating the need for transportation after screening the sand, thereby improving efficiency.

A hopper 10 is fixedly connected between the opposite side walls of the four support columns 9. A plate valve 19 is installed at the bottom outlet of the hopper 10. The top ends of the two right support columns 9 are fixedly connected to a fixing rod 11, and the top ends of the two left support columns 9 are fixedly connected to a fixing column 12. The top ends of the fixing column 12 are fixedly connected to a spring 15. A screen 13 is provided just above the hopper 10. The screen 13 is inclined to the lower right. Both ends of the front and rear side walls of 13 are vertically fixedly connected with connecting shafts 14, the two right connecting shafts 14 are rotatably connected to the tops of the two fixed rods 11, and the two left connecting shafts 14 are fixedly connected to the tops of the two springs 15. A slide plate 16 is fixedly connected in the extension direction of the right side wall of the screen 13, and baffles 17 are fixedly connected to the tops of the front and rear side walls and the left side wall of the screen 13. The front and rear baffles 17 extend to the right to the top of the right end of the slide plate 16, and a vibrator 18 is fixedly connected to the left side wall of the left baffle 17.
