Abstract

The pile feeder assembly with the replaceable pile cap comprises a dowel bar, the lower end of the dowel bar is connected with the pile cap, and a soil sealing device is arranged in the pile cap. An external thread is arranged on the outer wall of the lower end of the dowel bar; a connecting thread groove is formed in the center of the top of the pile cap in an inward concave mode, and internal threads are formed in the inner wall of the connecting thread groove; the soil sealing device comprises a sleeve with an opening in the upper end, and the upper edge of the sleeve extends outwards to form a circular-ring-shaped soil sealing plate; the sleeve can be arranged outside the connecting thread groove in a sleeving mode. The pile cap can be detached and replaced after being broken, and operation is convenient; the rod body of the dowel bar is provided with a graduated scale, so that the number of strikes can be conveniently recorded in the pile feeding process, and the rod body of the dowel bar is provided with an inclinometer, so that the inclination angle can be conveniently controlled when an inclined pile is fed; the annular pile pad is sleeved on the connecting thread groove, so that the pile pad can be conveniently fastened in the pile cap, and the pile pad can be effectively prevented from deviating and falling off; the soil sealing device can be automatically left on the pile top after pile feeding is finished, and pile top soil is effectively prevented from entering a pile core.
