Sand removing integrated plant based on environment-friendly highway engineering and used for highway pavement

The invention provides a sand removing integrated plant based on environment-friendly highway engineering and used for a highway pavement. The sand removing integrated plant comprises square conic hoppers, a dust collector, electric push rods, L-shaped guide rods and brush discs. The tops of the square conic hoppers are connected with corrugated hoses, connecting pipes penetrate through the top ofa plant body upwards to be connected to a dust suction pipe at the top of the dust collector, the front end and the rear end of the outer side of each square conic hopper are each provided with threeupper clamping boards, each upper clamping board located on the middle portion is connected with the corresponding electric push rod, the bottoms of the other two corresponding upper clamping boardsare connected with the corresponding L-shaped guide rods, the L-shaped guide rods penetrate through a bottom board outside square holes downwards to be connected to the top sides of lower supporting boards, rotary shafts sequen
