PROBLEM TO BE SOLVED: To provide an agitation mixing apparatus in which a clod sticking to a rotary shaft and an agitation blade and rotating together with the rotary shaft and the agitation blade can be inexpensively, easily and surely removed.SOLUTION: An agitation mixing apparatus 10 is provided that comprises: an excavation head 13 which is fitted to the tip of a rotary shaft 12 and excavates ground 8; agitation blades 14-16 which is fitted to the rotary shaft 12 and agitates and mixes excavated soil 9 and a solidification material S injected into the soil 9; and a corotation prevention plate 17 which is rotatably fitted to the rotary shaft 12 and prevents corotation of the excavated soil 9 and the agitation blades 14-16. In the agitation mixing apparatus 10, a clod shaving plate 20 for shaving the clod sticking to the rotary shaft 12 and the agitation blades 14-16 and rotating together with the rotary shaft 12 and the agitation blades 14-16 is detachably fitted to the corotation prevention plate 17, the clod shaving plate 20 is formed like a trapezoidal plate which has a horizontal leg 24 and an inclined leg 23 having a corner part 21 extending to the side where the rotary shaft 12 crosses the agitation blades 14-16 and having a corner part 22 reaching the vicinity of the corotation prevention plate 17 away from the agitation blades 14-16.SELECTED DRAWING: Figure 1
【課題】回転軸及び攪拌翼に付着して供回りする土塊を低コストで簡単かつ確実に取り除くことができる攪拌混合装置を提供する。【解決手段】回転軸１２の先端に取り付けられ、地盤８を掘削する掘削ヘッド１３と、回転軸１２に取り付けられ、掘削された土壌９と土壌９内に注入された固化材Ｓとを攪拌混合する攪拌翼１４〜１６と、回転軸１２に対して回転自在に取り付けられ、掘削された土壌９と攪拌翼１４〜１６との供回りを防止する供回り防止板１７と、を備えた攪拌混合装置１０において、供回り防止板１７に、回転軸１２と攪拌翼１４〜１６に付着して供回りする土塊を削る土塊削り板２０を着脱自在に取り付け、土塊削り板２０を、角部２１が回転軸１２と攪拌翼１４〜１６の交差する側まで延び、かつ、角部２３が攪拌翼１４〜１６から離れて供回り防止板１７の近くまで達してなる傾斜脚部２３と水平脚部２４とを有した台形板状に形成した。【選択図】図１
