10. The utility model provides a use method of anti-blocking sand screen that building engineering prefabricated component used which characterized in that: the method comprises the following steps:
s1: stirring the sand body: when the sand body is screened and conveyed, firstly, the sand body is infused into the feeding hopper (1) for scattering and discharging treatment, when sand enters the feeding hopper (1), a first driving motor (13) is started, the first stirring body (14) is driven to rotate by the rotation of the first driving motor (13), two second stirring bodies (15) are also driven to rotate by the connection of a chain (16), the loose sand or the block sand is scattered and conveyed by a plurality of rotating stirring sheets (18) which are arranged in a staggered way and a second stirring sheet (20), when the scattered sand needs to be discharged through the discharge end, the rotating rod (25) and the plurality of material pushing plates (26) are driven to rotate by utilizing the rotation of the second driving motor (24), thereby pushing the sand into the first screening drum (7) and the second screening drum (8) for screening treatment;
s2: screening and stirring sand bodies: when sand is screened, a support connecting rod (35), a first gear (36) and a first roller (37) are driven to rotate by the rotation of a fourth driving motor (34), so that a first screening roller (7) connected with the support is driven to rotate, a closed disc (31) is driven to rotate by the rotation of a third driving motor (32) while the first screening roller (7) rotates, so that a second screening roller (8) connected with the closed disc (31) is driven to rotate in the first screening roller (7) in the opposite direction, and sand can be screened more thoroughly by the simultaneous rotation of the first screening roller (7) and the second screening roller (8) in the opposite directions;
s3: conveying sand: the sand is screened by the first screening roller (7) and the second screening roller (8) and then falls to the surface of the first conveyer belt (10) to be conveyed, the sand on the surface is conveyed to the second conveyer belt (11) by the first conveyer belt (10), and finally the screened sand is discharged by the second conveyer belt (10) which is obliquely arranged upwards.
