Abstract
The invention relates to a feeding mechanism of a drill rod feeding device of a cement mixing pile driver. By means of the feeding mechanism, the problem that feeding is not smooth when an existing cement mixing pile driver drills holes is solved. The feeding mechanism comprises a sealed distribution box. The sealed distribution box comprises split sealing blocks. Each split sealing block is internally provided with a plurality of distribution runners and provided with at least one feed inlet and at least three distribution holes. At least three through holes are formed in the sealed distribution box. Drill rods are arranged in the through holes in a penetrating mode. Each drill rod is internally provided with at least two conveying pipes. 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 feeding mechanism has the advantages that additives in the conveying pipes of the drill rods 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.
