The construction method of the road construction device according to any one of claims 1-9, characterized in that it comprises the following steps:

S1. Prepare the site and the stones that need to be screened;

S2. Put stones into the primary screen pipe in batches, and the rotating mechanism drives the primary screen pipe to rotate horizontally, so that larger stones are rotated to the edge of the primary screen pipe, and at the same time, the vibration mechanism drives the The primary screen pipe vibrates up and down to break up the stones and promote the sieving of the stones. The larger stones will come out from the discharge port. After the larger stones basically go out from the discharge port, the The electromagnet is powered off, and the telescopic mechanism is manipulated at the same time to move the sealing plate downward. The sealing plate is tilted during the downward movement, and the stones on the sealing plate fall into the multiple screen tube. Since the vibration of the primary screen tube will drive the vibration of the secondary screen tube, the stones entering the secondary screen tube will be further screened, and the smaller stones will fall out of the sieve holes of the secondary screen tube, and the larger stones will The stones slide out from the bottom of the secondary screen pipe, and after the stones on the sealing plate slide, the telescopic mechanism is operated to move the sealing plate upwards to contact with the bottom of the primary screen pipe, and the The electromagnet is energized, and the sealing plate and the magnet are sucked together to seal the bottom of the primary screen, and the next batch of stones can be screened;

S3. Collect the stones falling from the sieve hole of the compound screen to obtain smaller stones, and collect the stones that slide out from the discharge port and the bottom end of the compound screen, namely Get larger stones.
