The invention relates to a raw material preparation machine for concrete preparation, in particular to the raw material preparation machine for the concrete preparation. The invention aims to solve the technical problem of difficultly providing the Raw material preparation machine for the concrete preparation, which is uniform in preparation and high in preparation speed, and requires little manpower consumption. In order to solve the technical problem above, the invention provides the raw material preparation machine for the concrete preparation, which comprises a collecting frame and the like; the top end of the left wall of the collecting frame is connected with a preparation frame; the left side of the collecting frame is connected with the bottom of the preparation frame; the top of the preparation frame is connected with a preparation mechanism; and the preparation mechanism is connected with a driving mechanism. According to the raw material preparation machine for the concretepreparation, the effects of uniform preparation, high preparation speed and little manpower consumption are achieved; the driving mechanism is arranged, so that the high preparation speed of concreteraw materials is facilitated; the preparation mechanism is arranged, so that the uniform preparation is facilitated; and a cylinder body, a piston, a second spring, a pull rod and a pull ring, so thatmulti-stage preparation is facilitated.
