[0047] The working principle of the present invention is as follows: when the present invention is used, the block boron nitride raw material is placed in the placement frame 1, the motor 408 is started to drive the threaded rod 407 to rotate, the threaded rod 407 thereby drives the slider 404 and the push plate 401 to move, the push plate 401 thereby pushes the block boron nitride raw material in the placement frame 1 into the guide tube 2, and then falls into the crusher 3 through the guide tube 2, the crusher 3 is started to crush the block boron nitride raw material, and then the vacuum pump 8 is started to evacuate air, so that the crushed boron nitride raw material in the crusher 3 is drawn into the barrel 6 through the feed pipe 5, and the rotating blade 501 arranged in the feed pipe 5 can be used to When the boron nitride raw material and the gas are mixed and flowed, a swirling effect is achieved, which increases the speed of the mixed flow and allows the boron nitride raw material to enter the barrel 6 more quickly. The dust-proof net on the dust-proof net frame 1402 in the anti-blocking mechanism 14 can protect the air inlet pipe 7 to prevent the boron nitride raw material from entering the air inlet pipe 7. After the boron nitride raw material enters the barrel 6, the connecting block 1203 is pulled to drive the cross plate 1201 to move to the right, and the cross plate 1201 is separated from the discharge pipe 603. At the same time, the cross plate 1201 compresses the first spring 1206, so that the boron nitride raw material in the barrel 6 falls into the left receiving barrel 10 through the discharge pipe 603. The dust-proof mechanism 13 can prevent the boron nitride raw material from flying out of the receiving barrel 10 when it falls into the receiving barrel 10, ensuring that the boron nitride raw material enters the receiving barrel 10, avoiding the waste caused by the flying boron nitride raw material not being collected, and protecting the environment around the equipment. At the same time, when the left receiving barrel 10 is receiving the material, the right receiving barrel 10 full of boron nitride raw material is removed, and an empty receiving barrel 10 is placed. The rotating mechanism 11 can realize a cyclic operation, thereby improving work efficiency. When the vacuum pump 8 is performing the exhaust work, the fan blade 1502 can drive the A rotating rod 1501 rotates, the first rotating rod 1501 thereby drives the first bevel gear 1505 to rotate, the first bevel gear 1505 drives the second bevel gear 1506, the second rotating rod 1507 and the third bevel gear 1508 to rotate, the third bevel gear 1508 thereby drives the fourth bevel gear 1510 and the third rotating rod 1511 to rotate, the third rotating rod 1511 thereby drives the rectangular rod 1513 and the cleaning brush rod 1514 to rotate, the cleaning brush rod 1514 thereby cleans the dustproof net on the dustproof net frame 1402 to prevent the boron nitride raw material from clogging the dustproof net, thereby ensuring the normal operation of the vacuum pump 8.
