[0029] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0030] like Figure 1As shown, it is a schematic structural diagram of a vibrating screening device for nickel pig iron raw materials of the utility model, the vibrating screening device is provided with a support frame 10 and a screening device, a vibrator 20 and a driving device located on the support frame 10, wherein the screening device comprises a screen 31, a collecting plate 32, a mounting plate 33 and a folding plate 34, the number of the mounting plates 33 is two, the mounting plates 33 are located on both sides of the screen 31, the mounting plates 33 are fixed on the support frame 10, the head end of the screen 31 is higher than the tail end, the folding plate 34 is located at the head end of the higher end of the screen 31, the folding plate 34 can be rotated with the upper end edge as the central axis, and the folding plate 34 is perpendicular to the mounting plate 33 The collecting plate 32 is located below the screen 31, a waste port 60 is provided at the end of the screen 31, the vibrator 20 is located below the collecting plate 32, the driving device is connected to the vibrator 20 through a conveyor belt, and the vibrating screening device of this embodiment also includes a buffer device 70, which is located between the screen 31 and the support frame 10. The vibrator 20 drives the collecting plate 32 to vibrate, and drives the screen 31 to vibrate at the same time. Since the screen 31 and the collecting plate 32 are both high at one end and low at the other end, both the screened material and the unscreened material will fall to the lower end for collection and use, thereby achieving the screening effect.

[0031] like Figure 2 As shown, the folding plate 34 of the utility model is provided with a connecting shaft 341, a plate body 342, a pull ring 343 and two lock buckles 344. The connecting shaft 341 is axially connected to the top corners of the two mounting plates 33, the plate body 342 is connected to the connecting shaft 341, the pull ring 343 is located below the outer side surface of the folding plate 34, and the two lock buckles 344 are located on both sides of the pull ring 343. The plate body 342 can be opened by pulling the pull ring 343. If the folding plate 34 does not need to be opened, the plate body 342 can be fixed by the lock buckles 344.

[0032] See also Figure 1 and Figure 3 As shown, the number of screens 31 of the utility model is two, and there is a distance between the two screens 31 and they are arranged in parallel up and down when not subject to external force. Specifically, positioning blocks 40 are respectively provided between the two screens 31 and at the top corners, and a compression spring 41 is provided between the upper and lower adjacent positioning blocks 40, and both ends of the compression spring 41 are hinged to the corresponding positioning blocks 40, and a support column 42 is provided on the inner end surface of the positioning block 40 and inside the compression spring 41. In other words, the compression spring 41 is sleeved on the outer circumferential surface of the support column 42, and when the compression spring 41 is not subject to external force and is in a static state, the support columns 42 on the inner side surfaces of the positioning blocks 40 corresponding to the upper and lower ends of the compression spring 41 do not abut each other, thereby preventing the positioning blocks 40 in the same compression spring 41 from abutting against each other, thereby affecting the adjustment of the positional relationship between the two screens 31.

[0033] Please refer to Figure 1 , Figure 3 and Figure 4 As shown, a positioner is provided on one end of the screen 31 of the utility model near the folding plate 34, and the positioner can manually adjust the overlapping area of ​​the two screens 31. Specifically, the positioner is provided with a positioning plate 51, a rotating plate 52, a slot 53, a rotating shaft 54 ​​and a bolt 55. The positioning plate 51 is fixed to the side of the lower screen 31 by the bolt 55, and the slot 53 is located on the positioning plate 51. In other words, the slot 53 is a groove-shaped body structure embedded in the positioning plate 51, and the slot 53 is arranged in an inclined shape. The rotating shaft 54 ​​is fixed to the upper screen 31. The lowermost point of the card slot 53 is located directly below the rotating shaft 54. One end of the rotating plate 52 is axially connected to the rotating shaft 54. A handle 56 is fixed to the outer side of the other end, and a clamping member 57 is fixed to the inner side. The clamping member 57 can be movably and stably engaged in the card slot 53. Specifically, a protruding structure can be provided in the card slot 53. The protruding structure can stably engage the clamping member 57. When subjected to an external force of sufficient size in the correct direction, the clamping member 57 can also be detached from a certain position and engaged in another position. The engaging principle belongs to the prior art and will not be described in detail here.

[0034] The vibrating screening device of the utility model can adjust the number and size of the mesh holes of the screen 31, and the overlapping area of ​​the two screens 31 is adjusted by moving the position of the clamp 57 in the clamping slot 53. Specifically, when it is necessary to adjust the size of the particle size of the screen 31, the folding plate 34 is first opened, and then the handle 56 is pulled, and the position of the clamp 57 in the clamping slot 53 is driven at the same time. Since the positioning plate 51 is fixed on the lower screen 31, and the rotating shaft 54 ​​is fixed on the upper screen 31, the rotating plate 52 associated with the two rotates around the rotating shaft 54 ​​as the center, thereby adjusting the distance and overlapping area between the upper and lower screens 31, thereby adjusting the number and size of the effective mesh holes of the two screens 31. In addition, in other embodiments, the above-mentioned positioner can also be set on the other opposite side of the screen 31, that is, the lower side, so as to improve the stability of the position of the screen 31.

[0035] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
