PROBLEM TO BE SOLVED: To provide a mixer which can adjust a blade angle of a mixing blade easily and surely. SOLUTION: An arm 8 with a mixing blade 7 is installed to be penetrated mixing shafts 3, 3'. Then, the arm 8 has a gear 10 and also a baffle implement 11, which is engaged with the gear 10 to prevent the arm 8 from moving around its shaft, is fastened to the mixing shafts 3, 3'. Then, when the blade angle of the mixing blade 7 is adjusted, a fixation of the arm 8 is released to pull out the arm 8 a little, and the arm 8 is pivoted around its shaft to adjust the blade angle of the mixing blade 7, thereafter the arm 8 is inserted into the mixing shafts 3, 3' while the gear 10 of the arm 8 and the baffle implement 11 are engaged, and a nut 9 is screwed to prevent the arm 8 from falling out. This can easily adjust the blade angle of the mixing blade 7 in one pitch unit of gears of the gear 10 installed to the arm 8. COPYRIGHT: (C)2007,JPO&INPIT
