9. The construction waste sorting device according to claim 1, wherein: the scraper conveyor comprises: the second rotates motor, second from driving wheel, second action wheel, second belt and scrapes the strip, the second rotates motor fixed connection on the shell of bar casing, the second from the driving wheel with the second action wheel all rotates the inside of connecting at the bar casing, the second belt is twined the second from the driving wheel with on the second action wheel, the second rotate the motor the output shaft with the one end middle part fixed connection of second action wheel, the figure of scraping the strip is a plurality of, a plurality of scrape the even fixed connection of strip in the length direction of second belt, the bottom inboard and the electro-magnet contact of second belt, the electro-magnet is located the top of silo under the fine soil.

10. The use method of the construction waste sorting device according to any one of claims 1 to 9, wherein: the using method comprises the following steps:

the method comprises the following steps that firstly, coarse crushing is carried out, building garbage is poured into the space between a first compression roller and a second compression roller from the top of a coarse crushing mechanism, a first driving motor and a second driving motor drive the first compression roller and the second compression roller, the first compression roller and the second compression roller respectively rotate clockwise and anticlockwise to roll the garbage, crushing is carried out, and the crushed garbage falls onto a magnetic belt conveyor from the bottom of a first protection shell;

step two, collecting coarse soil, wherein a first rotating motor in a magnetic belt conveyor provides drive, a first belt drives the crushed garbage to move towards a material receiving frame, the crushed concrete falls into the material receiving frame for collection, and reinforcing steel bars are adsorbed by magnet blocks, attached to the first belt and moved to the top of a fine crushing mechanism through conveying;

scraping and blanking the reinforcing steel bars, wherein the reinforcing steel bars are moved by a first belt and are blocked by a scraper during movement, so that the reinforcing steel bars are scraped and fall into the top of the fine crushing mechanism;

step four, fine crushing, namely, enabling the steel bars to fall between a second compression roller and a third compression roller, enabling a third driving motor and a fourth driving motor to provide driving for the third compression roller and a fourth compression roller, enabling the third compression roller and the fourth compression roller to rotate clockwise and anticlockwise respectively, rolling the steel bars, further crushing, crushing concrete attached to the surfaces of the steel bars to form fine soil, separating the fine soil from the steel bars, and discharging the steel bars and the fine soil from the bottom of a second protective shell after crushing to fall into a receiving hopper;

step five, the separation of fine soil and reinforcing bar, fine soil enters into the bar casing through connecing the hopper with the reinforcing bar together, fall on scraping the strip conveyer, the second rotates the motor and provides the drive, thereby provide the drive for fine soil and reinforcing bar, move to the top of electro-magnet, the electro-magnet sees through the second belt, adsorb the reinforcing bar, and fine soil falls down through the silo under the fine soil through the action of gravity, can accept the collection through outside container, continue to carry, the reinforcing bar moves the top of silo under the reinforcing bar, carry out the unloading through the silo under the reinforcing bar, fall down.
