The invention discloses a bridge gravel foundation bed paving machine. The machine comprises a main body and a top box installed on the top of the main body, wherein the inner wall of the main body isprovided with a gravel cavity; a conical cavity communicating with the bottom of the top box is arranged on the top wall in the gravel cavity in a penetrating mode; rotationally connected stone breaking devices are correspondingly arranged on the left side and the right side in the gravel cavity below the bottom of the conical cavity; a triangular block is fixedly arranged on the inner bottom wall of the gravel cavity below the rotationally connected stone breaking devices; a first sliding connection cavity is formed in the main body at the bottom of the gravel cavity; a guide connection cavity is formed in the inner wall of the rear side of the first sliding connection cavity; stone paving cavities extending up and down are arranged in the main body on the left side and the right side ofthe first sliding cavity; and top extension ends of the stone paving cavities on the left side and the right side extend to relative positions on the left side and the right side of the bottom of thegravel cavity respectively. The bridge gravel foundation bed paving machine is simple in structure, convenient to operate, and capable of improving the paving working efficiency and the paving quality of a bridge foundation bed, reducing the labor intensity and the labor amount of workers, and improving the working efficiency.
Description
technical field [0001] The invention relates to the field of bridges, in particular to a bridge gravel bed laying machine. Background technique [0002] Crushed stone is a common material used to lay bridge foundations, and the thickness of the crushed stone plays a key role in the performance of bridge foundations. The hammer crusher currently used in the market smashes stones through a high-speed rotating hammer head, the stone particles are uneven, the hammer crusher is noisy, the stability is not good, and the structure is complex and the operation is cumbersome. Existing road paving machines are all one-side gravel sprinkling operations, which cannot be adjusted according to actual conditions, and gravel and paving are performed as two procedures, which is inefficient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bridge gravel bed laying machine, which can solve the above-mentioned problems in the prio...
