[0042] The working principle of the present invention is as follows.

[0043] (i) The silicon carbide to be ground is fed into the second fixed box 211 through the feeding pipe 1, and then the first electric cylinder 216 is started, and the first electric cylinder 216 pushes the upper sealing plate 215 to slide along the first limiting rod 204, and the upper sealing plate 215 drives the first rotating plate 207 to slide along the third limiting rod 403 through the first sliding cylinder 205. When the spline hole of the first rotating plate 207 contacts the spline on the outer surface of the third limiting rod 403, the first rotating plate 207 and the third limiting rod 403 form a spline match. When the first grinding ball 208 contacts the first floor 213, the first electric cylinder 216 stops working, and the second electric cylinder 404 is started. The second electric cylinder 404 drives the second rotating plate 207 through the fixed rod 402. The sliding cylinder 410 slides along the third limiting rod 403. When the second rotating plate 413 contacts the spline hole and the spline of the fourth limiting rod 419, the first motor 201 starts. The first motor 201 drives the third limiting rod 403 to rotate through the first limiting rod 204. The third limiting rod 403 drives the first rotating plate 207 to rotate through the spline. The first rotating plate 207 drives the first grinding ball 208 and the first fixed box 209 to move. The silicon carbide in the second fixed box 211 is ground by the first grinding ball 208, and the first fixed box 209 drives the first brush 210 to move. The silicon carbide particles on the first floor 213 are cleaned by the first brush 210, thereby facilitating grinding.

[0044] (ii) The ground silicon carbide particles fall onto the second rotating plate 413 through the first leakage hole 214, and the third limiting rod 403 rotates to drive the second connecting rod 411 to move, which drives the first gear 412 to rotate through the ring gear 401, and drives the first scraper 420 and the brush on the first gear 412 to move, and the silicon carbide particles on the second rotating plate 413 are sent into the fourth leakage hole 414 through the first scraper 420 and the brush on the first gear 412 and fall into the third fixed box 407.

[0045] (III) The third limiting rod 403 drives the fourth limiting rod 419 to rotate, the fourth limiting rod 419 drives the second rotating plate 413 to rotate, the second rotating plate 413 drives the second grinding ball 416 and the fourth fixed box 417 to move, the silicon carbide particles in the third fixed box 407 are ground by the second grinding ball 416, and the silicon carbide particles on the second leakage hole 406 are cleaned by the second brush 418, so as to facilitate grinding, and the ground silicon carbide particles fall into the collecting box 502 through the second leakage hole 406.

[0046] (IV) When the first motor 201 rotates, the turntable 303 is driven to rotate through the transmission chain 301, and the turntable 303 drives the moving block 305 to move through the driving block 304, and the moving block 305 drives the driving rod 307 to slide back and forth along the second limit rod 316. At the same time, the moving block 305 drives the side block 308 to reciprocate through the transmission rod 317, and the side block 308 drives the piston rod 312 to reciprocate along the first air intake cylinder 310 through the first connecting rod 309, thereby realizing the inflation of the second fixed box 211, and inflating the third fixed box 407 through the air transmission pipe 313, thereby realizing the blowing up of silicon carbide particles, so as to better grind.
