By arranging the second pulley 14, the spring 15, the vibration block 16, the third pulley 17 and the stop block 18, the ground powder can be screened and spread for the second time, thereby avoiding the accumulation of powder in the device.

[0022] See also Figure 1 and Figure 4 A linear motor 19 is connected to the left side of the box body 2 by bolts, and the moving end of the linear motor 19 is fixedly connected to the baffle 12. By setting the linear motor 19 and the baffle 12, the function of grinding sand and gravel of different sizes in batches is achieved, which is beneficial to improving the grinding efficiency. The output end of the controller 13 is electrically connected to the linear motor 19 in one direction.

[0023] See also Figure 1 The inner cavity of the box body 2 is fixedly connected with a guide block 20. By setting the guide block 20, large particles of sand and gravel can enter the box body 1 from the box body 2 for grinding.
