This invention provides a graded crushed stone paving device for road reconstruction subgrade, comprising a support assembly, a power assembly, and a material feeding assembly. The support assembly includes a conical box, which is fixedly connected to a material pipe. The conical box is connected to a U-plate, and the U-plate is connected to symmetrical long rods, which are respectively connected to guide blocks. The U-plate is connected to a motor bracket. The power assembly includes a motor, which is connected to a motor bracket. The output shaft of the motor is connected to a drive gear, and the U-plate bearing is connected to the central shaft of symmetrical driven gears. This invention relates to the field of road reconstruction technology, and particularly to a graded crushed stone paving device for road reconstruction subgrade. Addressing the shortcomings of existing technologies, this invention develops a graded crushed stone paving device for road reconstruction subgrade. This invention disperses and spreads graded crushed stone, allowing it to fall onto the subgrade surface, then disperses, vertically compresses, flattens, compacts, and rolls it to achieve graded crushed stone paving.
