Abstract

PURPOSE: To get easy and swift exchanging works for abraded sliding mouth piece by uniting sliding mouth piece of valve, valve, its tenon and boss for accepting tenon, and composing this unit outside of feeding chamber in a condition of free take out.
CONSTITUTION: Hopper 1 is composed of mixing chamber 2 in upper part and feeding chamber 3 in under part and thus can divide in two-upper and lower part. Moreover, feeding pipe 6 is connected with back wall part 5 of feeding chamber 3 and a pair of pump cylinder 8, 8 are parallely connected with front wall part 7. It is constructed that sliding mouth piece 23 which is attached at front opening end 21 of guid hole 15 of valve 14, valve 14 and projected tenon 24 which is provided in valve 14 and boss 30 which accept this tenon 24, all in one unit and composed to be in free for take out at out side position of feeding chamber 3.
