EXCAVATION AGITATION DEVICE
To provide an excavation agitation device which reduces wear applied between an anti-corotation blade and an excavation shaft.SOLUTION: Excavation shafts 2 are provided so as to be separated into a first excavation shaft 2a, a second excavation shaft 2b and a third excavation shaft 2c in this order from above, and an agitation blade 3 is provided on the first excavation shaft 2a, an anti-corotation blade 4 is provided on the second excavation blade 2b, and an excavation blade 5 is provided on the third excavation shaft 2c. The second excavation shaft 2b is provided with a convex part 24 formed of a first convex part 24a and a second convex part 24b, and a thrust bearing 61 is provided so as to be brought into contact with the upper surface and the lower surface of the second convex part 24b. A radical bearing 62 is provided so as to be brought into contact with the outer periphery of the first convex part 24a, is covered with a bearing part 41, a housing case 7 and a gun metal cover 82, and allows a grease to be injected.SELECTED DRAWING: Figure 3
【課題】供回り防止翼と掘削軸との間にかかる摩耗を低減させるようにした掘削撹拌装置を提供する。【解決手段】掘削軸２を上から順に、第一掘削軸２ａ、第二掘削軸２ｂ、第三掘削軸２ｃに分離可能に設け、第一掘削軸２ａに撹拌翼３、第二掘削軸２ｂに供回り防止翼４、第三掘削軸２ｃに掘削翼５を設ける。この第二掘削軸２ｂには、第一凸状部２４ａや第二凸状部２４ｂからなる凸状部２４が設けられており、この第二凸状部２４ｂの上面と下面に接するようにスラストベアリング６１を設ける。一方、第一凸状部２４ａの外周に接するようにラジアルベアリング６２を設け、これらを軸受部４１やハウジングケース７、砲金カバー８２で覆い、グリスを注入できるようにする。【選択図】図３
