Raw material screening device for building concrete processing

The raw material screening device for building concrete processing comprises a machine base and a screening disc, supports are installed on the two sides of the top of the machine base, a guide rod is connected between the two supports in a butt joint mode, springs are connected to the two ends of the guide rod in a sleeved mode, one end of each spring is fixed to the corresponding support, the screening disc is arranged above the machine base, and the screening disc is arranged on the machine base. And clamping seats are fixed on the two sides of the sieve tray. According to the raw material screening device for building concrete processing, C-shaped butt joint grooves in the inner sides of the clamping bases and guide rods are clamped and limited, a screening disc can be conveniently and rapidly assembled, on the contrary, the screening disc is pulled upwards, the clamping bases on the two sides of the screening disc are rapidly separated from the guide rods, and the screening device can be conveniently cle
