Material conveying seal box for cement mixing pile driver
The invention relates to a material conveying seal box for a cement mixing pile driver. The material conveying seal box solves the problems that materials are unevenly fed when an existing cement mixing pile driver is used for drilling holes. The material conveying seal box comprises a main seal box body, a main rod penetrating hole, at least two auxiliary rod penetrating holes, a main drill rod, auxiliary drill rods, a movable seal box body and a main rod installation hole. At least two main rod conveying pipes are arranged in the main drill rod. At least two main rod feeding inlets are formed in the movable seal box body, and a main rod feeding mechanism is arranged in the movable seal box body. At least two auxiliary rod conveying pipes extending downwards in the axial direction are arranged in each auxiliary drill rod. At least two auxiliary rod feeding inlets are formed in the main seal box body, and an auxiliary rod feeding mechanism is arranged in the main seal box body. The material conveying seal box has the advantages that slurry is evenly distributed; a distributor does not need to be lifted up along with the drill rods which are lifted up; additives can be conveyed into the conveying pipes in the drill rods at the same time in construction, material feeding is smooth, and the additives in the conveying pipes in the drill rods are evenly distributed.
