[0032] In the embodiment, the feeding passage 72 facilitates pouring of the metal silicon powder stored in the storage barrel 71 into the discharging assembly 8.

[0033] As a preferred embodiment, on the basis of the above structure, further, the discharging assembly 8 comprises a vertical shaft 81, a third taper tooth 82, a discharging disc 83 and a discharging groove 84, the vertical shaft 81 penetrates the fixed pipe 73 and is bearing-connected with the fixed pipe 73, the third taper tooth 82 is fixedly sleeved to the top end outer side of the vertical shaft 81, the discharging disc 83 is fixedly connected to the bottom end of the vertical shaft 81, two discharging grooves 84 are symmetrically formed on the upper end face of the discharging disc 83, and the two discharging grooves 84 correspond to the two feeding passages 72 and have equal widths.
