The upper surface of the mounting plate 5 is fixedly connected to the stepping motor 6. The inner wall of the top of the connecting pipe 1 is fixedly connected to a symmetrically distributed guide rod 7. The inner wall of the top of the connecting pipe 1 is located between the guide rods 7 and is rotatably connected to a screw rod 9. One end of the guide rod 7 is fixedly connected to a bottom plate 8 rotatably connected to the screw rod 9. A matching platform 12 is provided on the top of the truncated cone-shaped hollow frame 11. The upper surface of the matching platform 12 The surface is provided with a screw hole 13 threadedly connected to the screw rod 9, and the upper surface of the matching platform 12 is inlaid with a sliding sleeve 14 slidingly connected to the guide rod 7.

The lower surface of the end cover body 3 is fixedly connected with a cannula 20. The stepping motor 6 drives the screw rod 9 to rotate, and the truncated cone-shaped hollow frame 11 can move up and down under the restriction of the guide rod 7. Before the mill works, the truncated cone-shaped hollow frame 11 is first driven to move downward so that the bottom of the truncated cone-shaped hollow frame 11 extends from the insert pipe 20, and the raw material enters the insert pipe 20 from the connecting pipe 1, and then impacts the truncated cone-shaped hollow frame 11. The raw material is dispersed and sprayed out from the truncated cone-shaped hollow frame 11 and enters the interior of the sand mill. The distance that the truncated cone-shaped hollow frame 11 extends from the insert pipe 20 is adjusted, and then the opening size when the raw material is sprayed from the insert pipe 20 is adjusted, thereby adjusting the spraying speed and spraying width of the raw material.
