The utility model has low wear degree and long service life. The fault rate is low, spare parts do not need to be replaced frequently, the working efficiency is improved, and the operation cost of enterprises is reduced.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Fig. 2 is an enlarged view of the shaft end of the present utility model.
In the figure: 1. a screen shaft; 2. a screen plate; 3. a mesh plate hole; 4. a shaft sleeve is arranged on the screen plate; 5. a lower shaft sleeve of the screen plate; 6. a roller; 7. a link plate; 8. a baffle; 9. circlips for shafts; 10. a gasket; 11. a shaft sleeve; 12. a circlip for the first shaft; 13. the second shaft is provided with a circlip.
Detailed Description
The utility model is further described below with reference to the accompanying drawings:
as shown in figure 1, the utility model comprises a plurality of net plates 2, a plurality of net plates 2 are connected together by net plate shafts 1 from left to right, and net holes 3 are uniformly distributed on the surface of the net plates 2. The top and the bottom of the screen plate 2 are provided with a section of screen plate upper shaft sleeve 4 and two sections of screen plate lower shaft sleeves 5, the screen plate upper shaft sleeve 4 is positioned between the two sections of screen plate lower shaft sleeves 5, and the inner diameters of the screen plate upper shaft sleeve 4 and the screen plate lower shaft sleeve 5 are the same and coaxial with the screen plate shaft 1. The screen plate forms a chain wheel transmission system through the roller 6 and the chain plate 7.
As shown in figure 2, the baffle plate 8 is directly arranged along the edge of the screen plate, prevents dirt from entering through the edge of the screen plate, and limits the axial deflection of the screen plate through the elastic retainer ring for the side shaft, thereby improving the stability of the screen plate in the operation process. The gaskets 10 are arranged on two sides of the roller 6, so that the elastic retainer ring 9 is isolated from the shaft sleeve 11 and the roller, and side abrasion of the roller in the use process is reduced. The chain plate 7 is connected with the shaft sleeve 11 in a thickening mode and rotates flexibly to replace the plastic chain plate structure adopted in the original design, so that the strength is improved, and the chain plate is not easy to damage. The shaft sleeve 11 is arranged on the screen plate shaft 1, and the axial deflection of the chain plate 7 is limited by the elastic retainer ring 12 for the shaft, so that the consistency of the roller 6 and the track direction is improved.
