[0028] As a further implementation of this scheme, one end of the motor main shaft 4 is rotatably connected to the inner side of the L support rod 2, the conveyor belt 5 is inclined, and the number of partitions 6 is a certain number, and the partitions 6 have the effect of blocking the basalt to prevent the basalt from falling;

The conveyor belt 5 rotates to transport the basalt upward. When the basalt is at the top, the basalt falls onto the feed port 9 and enters the spiral buffer tube 8 from the feed port 9.

The basalt falls from the discharge port 24 onto the extrusion component body 1. At this time, the basalt can be processed to achieve the effect of buffering the fall of the basalt and protect the service life of the extrusion component body 1.
