[0003] During use, a device for evenly spreading mixture for road construction disclosed in this patent application uses a second frame to rotate inside a first frame, so that the material drop holes are blocked by misalignment or the size of the holes is adjusted, so as to facilitate the control of the amount of gravel dropped. At the same time, the telescopic activities of the first frame and the second frame can be adjusted to adapt to the construction of roads of different widths. However, during such use, when the telescopic activities of the first frame and the second frame are adjusted, the material drop holes located at the left and right edge positions will not be blocked by misalignment or the size of the holes will not be adjusted, so that the gravel drop in the middle and on both sides of the equipment is uneven, which reduces the practicability of the equipment. For this reason, we propose a device for evenly spreading mixture for road construction. Utility Model Content
