[0029] Embodiment 2

[0030] As Figure 1As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the adjustment device includes a fixed frame 601, which is fixedly connected to the surface of the fixed frame 1. A motor B602 is fixedly connected to the side of the fixed frame 601. A threaded rod 603 is fixedly connected to the output end of the motor B602. The other end of the threaded rod 603 is rotatably connected to the inner wall of the fixed frame 601 through a bearing.

[0034] The working principle of this sand screening device for construction will be explained in detail below.

[0035] like Figures 1-3 As shown, in use, first start the motor A504 to drive the connecting plate 505 to rotate, which in turn drives the fixed rod 506 to rotate around the output end of the motor A504. At the same time, the fixed rod 506 will slide inside the slide groove 512, thereby causing the rotating plate 502 to swing outside the fixed column 501. Then, the end of the rotating plate 502 away from the fixed column 501 will drive the fixed sleeve 507 to move back and forth left and right. Then, the fixed sleeve 507 will drive the movable rod 509 to move back and forth left and right.

The side rollers 514 slide inside the chute 512, thereby reciprocating through the action of the screen frame 511 to screen sand. When it is necessary to adjust the angle of the rectangular frame 3, the motor B602 is started to drive the threaded rod 603 to rotate. Then, the moving block 604 connected to the outer wall threadedly moves closer to the fixed frame 1. Then, the connecting rods 605 fixedly connected on both sides of the moving block 604 move simultaneously. Then, under the action of the support rod 606, the rectangular frame 3 will rotate around the rotating rod 2, thereby raising one side of the rectangular frame 3, thus realizing the adjustment of the tilt angle of the rectangular frame 3.
