Example Embodiment

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0018] See Figure 1~3 In the embodiment of the present invention, a construction gravel screening device includes a base 1 and a screening box 8. A plurality of iron blocks 3 are arranged on the upper side of the base 1 and the iron blocks 3 are arranged on the upper side A spring 5, an electromagnet 4 is connected to the upper end of the spring 5, a support platform 2 is provided on the upper side of the electromagnet 4, and a slide rail 6 is provided on the upper side of the support platform 2, and the slide rail 6 is T A sliding rail with a font structure, the lower end of the screening box 8 is provided with a support plate 7 symmetrically, the lower end of the support plate 7 is connected with the slide rail 6, and the upper right end of the support platform 2 is provided with a motor 9, so The output end of the motor 9 is provided with a turntable 10, the front side of the turntable 10 is provided with a rotating shaft 11 on the outer periphery, and the right side of the right support plate 7 is provided with a connecting seat 12, the connecting seat 12 and the rotating shaft 11 A connecting rod 13 is provided therebetween, and both ends of the connecting rod 13 are rotatably connected with the connecting seat 12 and the rotating shaft 11. The inside of the screening box 8 is sequentially provided with a primary screen 14 and an intermediate screen from top to bottom. The screening mesh 15 and the advanced screening mesh 16, the primary screening mesh 14, the intermediate screening mesh 5 and the advanced screening mesh 16 are all inclined at a certain angle, and the lower end of the screening box 8 is provided with a first discharge pipe 17, the right side of the screening box 8 is located on the upper side of the primary screening screen 14, the intermediate screening screen 15 and the high-level screening screen 16 are all provided with a second discharge pipe 18, a motor 9, a slide rail 6 and The setting of the electromagnet 4 can make the screening box 8 move up and down by turning on and off the electromagnet 4 during operation. The rotation of the motor 9 drives the screening box 8 to move left and right. The structure design is reasonable and the screening effect is good. After a long time of use, the screen will not block the holes, which not only improves the work efficiency, but also greatly reduces the work cost.
[0019] The upper left part of the screening box 8 is provided with a feeding hopper 23, the lower left part of the feeding hopper 23 is provided with a rotating seat 24, and a threaded rod 25 is provided on the rotating seat 24. The left end of 25 is provided with an adjusting wheel 26, the threaded rod 25 is threadedly connected with a baffle plate 27, the right end of the baffle plate 27 is provided inside the hopper 23, and the right end of the threaded rod 25 rotates with the rotating seat 24 Connected, the feed hopper 23 is provided with a chute that cooperates with the baffle plate 27.
