Drill rod feeding device of cement mixing pile driver
The invention relates to a drill rod feeding device of a cement mixing pile driver. By means of the drill rod feeding device, the problem that feeding is not even when an existing cement mixing pile driver drills holes is solved. The drill rod feeding device comprises a sealed distribution box, at least two distribution runners and at least two through holes. Each through hole is internally provided with at least two distribution holes. Drill rods capable of rotating in the circumferential direction are arranged in the through holes in a penetrating mode. Each drill rod is internally provided with at least two conveying pipes axially extending to a conveying pipe at the lower end of the drill rod. The conveying pipes are arranged in a staggered mode in the vertical direction and correspond to the distribution holes in a one-to-one mode. The conveying pipes are connected with the distribution runners through communicating structures. The drill rod feeding device has the advantages that additives can be conveyed to the conveying pipes in the multiple drill rods at the same time in the construction process and are distributed evenly; supply is even, and insufficient slurry supply is avoided; the drilling difficulty is reduced, and holes with larger cross sections can be drilled each time.
