[0029] In view of the above problems, the screening structure of the large crushing vibrating screen provided by the embodiments of the present application is described in detail below in combination with the drawings.

[0030] As shown in Figure 1 , Figure 2 and Figure 3 , the screening structure of the large crushing vibrating screen comprises a screen plate frame 1 and a dust cover 3, and the dust cover 3 is arranged on the screen plate frame 1. In the present application, the large crushing vibrating screen generally refers to a vibrating screen with a screen plate of 1800mmX1250mm or above. The screen plate of these vibrating screens is integrally arranged, thus the technical problems proposed in the background art appear. The present application is improved in view of this. Specifically, the present application further comprises a screen plate frame 2, a screen plate 4, and a caulking strip 5. The caulking strip 5 is composed of at least three abutting metal strips, and is used to fill the gap between the screen plates 4.

[0031] Different from the existing whole screen plate 4, in order to avoid hoisting the screen plate 4, the height of the dust cover 3 is set to be at least the width of 1.5 screen plates 4 to facilitate the turning direction of the screen plate 4 in the dust cover 3. One side of the dust cover 3 is provided with a hinge-mounted opening and closing door 31, and the screen plate 4 enters the screen plate frame 1 from the opening and closing door 31 for installation or replacement operation. The bottom of the opening and closing door 31 is provided with an operation platform 32 on the dust cover 3 for workers to work on during maintenance or installation. The screen plate frame 2 is fixedly arranged on the inner side of the screen plate frame 1, the screen plate 4 is arranged in multiple pieces and fixedly arranged on the screen plate frame 2 by screws, and the caulking strip 5 is embedded in the gap between the screen plates 4.

[0032] Specifically, the present application improves the 1800mmX1250mm screen plate, which is divided into six screen plates 4. Each screen plate 4 is provided with a plurality of holes 41, and the caulking strip 5 is embedded in the gap between the screen plates 4. Figure 4The screen plate 4 is designed to be 600mm x 600mm x 30mm in size. The screen plate 4 is surrounded by a screen frame 41 for easy placement on the screen plate frame 2. The screen frame 41 is embedded with a screen 42. The four corners of the screen frame 41 are provided with screw holes 44 for easy screw fastening to the screen plate frame 2. A reinforcing beam 43 is provided on one side of the bottom of the screen plate 4 to increase the support strength during the laying process. The reinforcing beam 43 is designed in a grid shape and is located in the center.

[0033] In order to use the sieve plate 4, the sieve plate frame 2 of this application is used to place the sieve plate 4, such as Figure 3 As shown, the sieve frame 2 is welded and fixed by crossbeams 21 and vertical beams 22 to facilitate the placement of the sieve plate 4. Three crossbeams 21 are provided, welded to the two side walls and the middle position of the sieve frame 1 respectively; four vertical beams 22 are provided, two of which are welded to the two side walls of the sieve frame 1 and simultaneously welded between the crossbeams 21 and the middle crossbeam 21 on the side walls of the sieve frame 1, and the other two vertical beams 22 are welded between the crossbeams 21 and the middle crossbeam 21 on the side walls of the sieve frame 1. Figure 2 As shown, six sieve plates 4 are arranged on the sieve plate frame 2 along both sides of the sieve plate frame 1. Sealing strips 5 are positioned along the length of the sieve plate frame 1, with one sealing strip 5 spanning between two sieve plates 4. This ensures that when replacing a sieve plate 4, prying up any single sealing strip 5 guarantees that at least half of the sieve plate 4 remains restrained. Only when the sealing strip 5 at the desired location is pried up can the corresponding sieve plate 4 be easily disassembled and reassembled, while the steps of adjacent sieve plates 4 remain unobstructed.

[0034] This application divides the original single screen plate into six pieces, which are then laid on a specific screen plate frame 2 in a floor-like manner and secured with screws. Gaps are then filled with sealant strips 5. Simultaneously, to facilitate access of the screen plates 4 into the screen plate frame 1, the dust cover 3 is modified. The height of the dust cover 3 is set to allow passage of at least 1.5 times the width of the screen plates 4. An opening door 31 is provided on one side of the dust cover 3, and an operating platform 32 is provided on the bottom of the dust cover 3. Thus, during use, the screen plate, which previously required hoisting as a whole, is divided into six pieces. Maintenance and replacement personnel can directly hold the screen plates 4 and enter the screen plate frame 1 for replacement work, eliminating the need for hoisting and avoiding hoisting risks. Furthermore, the wear and tear on the screen plates 4 varies at different locations. When wear or damage occurs, only a single worker needs to replace the worn or damaged screen plate 4, saving both material and labor costs.

[0035] In one embodiment, to facilitate the fastening of the sealant strip 5, each sealant strip 5 is provided with a screw hole in the middle and is fastened to the crossbeam 21 by screws.

[0036] In one embodiment, such as Figure 5 As shown, after the screen plate 4 and the gap-filling strip 5 are installed and fastened on the screen plate 4, the gaps are filled by the gap-filling strip 5, and it vibrates during equipment operation. Therefore, it is inconvenient to pry out a single screen plate 4 when replacing it individually. Thus, this application sets four gap-filling strips 5, one of which must span between two screen plates 4. Furthermore, the gap-filling strips 5 are marked as front gap-filling strip 51 and rear gap-filling strip 52 according to the screening infeed / outfeed sequence. A pry hole 53 is constructed between the front gap-filling strip 51 and the rear gap-filling strip 52. In this way, because the gap-filling strip 5 is relatively small, it is easier to pry it open through the pry hole 53. Opening the gap-filling strip 5 reveals a gap groove, through which the screen plate 4 can be easily pried up.

[0037] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
