Abstract:
1. A composite continuous feeder, which is arranged above a growth furnace, comprising: a primary feeder which is coupled with the growth furnace and includes a feeding chamber, a first material holder and an elevator mechanism; wherein the feeding chamber communicates with the growth furnace; wherein the first material holder holds a plurality of material bits; and wherein the elevator mechanism is coupled to the feeding chamber and the first material holder and used to lift or lower the first material holder in the feeding chamber; and a secondary feeder which is coupled with the growth furnace and includes a second material holder, a buffering discharger and a material discharging guide tube; wherein the second material holder holds a plurality of material bits; wherein the buffering discharger is arranged at an outlet of the second material holder to receive the material bits output by the second material holder; and wherein the material discharging guide tube is corresponding to a buffering discharge opening of the buffering discharger and communicates with the feeding chamber, wherein the feeding chamber includes a positioning block; herein the first material holder includes a hollow casing to hold the material bits, an output opening for discharging the material bits, a positioning slot corresponding to the positioning block for latching, and a material stopper corresponding to the output opening; wherein the positioning slot is arranged on an outer surface of the casing and coupled thereto, and latches the positioning block to restrict movement of the first material holder; and wherein the material stopper functions as a switch of the output opening to control the output of the material bits.
