the supporting rod is vertically arranged on the ground, and one side of the top of the supporting rod is rotationally connected with the axis of the cam;

6. A road construction device according to claim 1 wherein the material lifting assembly is a winch cage which is rotated by a drive motor located above the top of the feed channel.

7. The construction method of a road construction device according to any one of claims 1 to 6, comprising the steps of:

s1, preparing a field and stones to be sieved;

s2, placing stones into the primary screen pipe in batches, driving the primary screen pipe to horizontally rotate by the rotating mechanism, enabling larger stones to be rotated to the edge of the primary screen pipe, driving the primary screen pipe to vibrate up and down by the vibrating mechanism, playing a role of breaking up the stones, promoting the stones to be screened, enabling the larger stones to come out of the discharge port, powering off the electromagnet after the larger stones substantially come out of the discharge port, simultaneously operating the telescopic mechanism, enabling the sealing plate to move downwards, enabling the sealing plate to incline in the downward movement process, enabling the stones on the sealing plate to fall into the secondary screen pipe, enabling the stones entering the secondary screen pipe to be further screened due to the vibration of the primary screen pipe, enabling the smaller stones to fall out of the screen holes of the secondary screen pipe, and enabling the larger stones to slide out of the bottom end of the secondary screen pipe, after the stones on the sealing plate slide, the telescopic mechanism is operated to enable the sealing plate to move upwards to be in contact with the bottom of the primary sieve tube, the electromagnet is electrified, and the sealing plate and the magnet are attracted to seal the bottom of the primary sieve tube, so that the next batch of stones can be screened;
