The ground material is filtered through a filter 5 and then conveyed to an extension barrel 7 to prevent the mixing of ore powders of different sizes. The rotation of the eccentric disk 10 drives the pull rod 11 to rotate and displace, thereby pulling the piston 12 and the one-way valve 13 to slide in the discharge pipe 14, so that the ore powder in the extension barrel 7 and the transfer barrel 6 can be ejected through the one-way valve 13. The specific structural arrangement of the assembly is as follows;
