The utility model discloses a soil flora culture device with a split type bottom double-spiral belt and a reverse screw, and relates to a stirring device. The barrel bottom and the barrel body are mounted in the base; the lower end of the barrel body is communicated with the barrel bottom; the connecting cover is fixedly connected with the upper end of the barrel body; the barrel cover is connected with the connecting cover through a connecting device; the driving mechanism is fixed in the base; the stirring mechanism is mounted in the barrel body; two ends of the stirring mechanism are respectively connected with the barrel cover and the driving mechanism. According to the utility model, through the mutual matching among the outer-ring helical ribbon, the inner-ring helical ribbon and the connecting rod, the mixing and stirring of soil in the vertical direction, the cutting and mixing and stirring in the horizontal direction, the scraping of the inner wall of the barrel body and the filling of soil in a central hole in the barrel body can be realized; the stirring mechanism not only can realize rotary stirring around the central shaft, but also has upward thrust of a stirring rod and downward pressure of a helical ribbon, soil with the humidity of about 45% can be uniformly stirred, even large soil can be uniformly stirred, the stirring effect is strong, and the efficiency is high.

This utility model discloses a conical bidirectional mixing head for cement mixing pile construction, comprising a hollow outer rod, within which a hollow inner rod is nested. A vertical main shaft is fixedly connected to the end of the inner rod, which serves as the mixing shaft and is a hollow shaft with a closed conical end. The inner rod is coaxially fixedly connected to the top of the vertical main shaft, and their inner cavities are interconnected. Straight blades and a grouting pipe communicating with the inner cavity of the vertical main shaft are vertically mounted on the vertical main shaft. The straight blades are the main mixing blades. A positioning sleeve is fitted onto the vertical main shaft. The outer rod and the positioning sleeve are fixedly connected through the free end of a C-shaped mixing blade, which is a secondary mixing blade. This mixing head achieves bidirectional rotation while improving and optimizing its structural form, resulting in stronger mixing capacity and anti-drilling characteristics, which is beneficial to the stability and uniformity of pile formation and can improve construction efficiency to a certain extent.

The utility model discloses a planetary bidirectional stirring head for cement mixing pile construction, including hollow outer pole, the hollow inner pole is nested in the outer pole, the bottom fixed docking of outer pole is on the casing of gear box, and the inner pole inserts gear box inside and is fixed docking with the vertical main shaft of gear box, and the vertical main shaft is as the stirring main shaft, and is the hollow shaft of closed cone shape for the end, and the inner tube is coaxial fixed docking with the vertical main shaft top and the inner chamber is through, and the vertical main shaft is vertically provided with straight plate blade and the grouting pipe that communicates with the inner chamber of vertical main shaft, and the vertical main shaft has the auxiliary shaft through gear box switching, and the auxiliary shaft is as the auxiliary stirring axle, and is equipped with the auxiliary stirring blade on the auxiliary stirring axle. This stirring head can realize bidirectional stirring, and the structural form that the main stirring axle is combined with the auxiliary stirring axle has stronger stirring capacity and anti -bore -drill characteristic, especially when handling high water content silt, high plastic clay, contains thin sand interlayer or organic matter soil and so on complex stratum, has obvious advantage, and the quality of more guarantee is formed in a pile.
