The specific embodiment
As shown in Figure 1, it is the structural representation of the coal screen 10 of the utility model one preferred embodiment.Coal screen 10 comprises: bracing frame 100, feeding warehouse 200, feed conveyor belt 300, cylinder 400, separating plate 500 and fines belt conveyor 600.
As shown in Figure 2, it is the structural representation of the bracing frame 100 of the coal screen 10 shown in Fig. 1.Bracing frame 100 is positioned on level ground.
Refer to Fig. 3, it is the structural representation of the feeding warehouse 200 of coal screen 10.Feeding warehouse 200 is located at bracing frame 100 away from one end of level ground, and feeding warehouse 200 has inlet point 210 and discharging opening 220.
Feed conveyor belt 300 one end are connected with level ground, and the other end is connected with the inlet point 210 of feeding warehouse 200.Feed conveyor belt 300 is by its transmission of external drive device drives, and external drive equipment adopts motor conventionally.Needs grate coal charcoal is positioned in feed conveyor belt 300, and feed conveyor belt 300 is transported coal to inlet point 210 places of feeding warehouse 200.Coal enters from inlet point 210, under the effect of gravity from discharging opening 220 out.
In the present embodiment, coal screen 10 also comprises baffle plate 700, and baffle plate 700 is located on bracing frame 100, and arranges around the inlet point 210 of feeding warehouse 200.At inlet point 210, baffle plate 700 is set around, can prevents that coal from overflowing when entering inlet point 210.
Please refer to Fig. 4 and Fig. 5, its cylinder 400 that is respectively coal screen 10 is coated with mesh screen 800 and removes the structural representation after mesh screen 800.
Cylinder 400 is connected on bracing frame 100 by elastic component 900, and the axis of cylinder 400 is provided with rotating shaft 410, and rotating shaft 410 is tilted with level ground.In rotating shaft 410, be installed with cam 412, the side of cylinder 400 is coated with mesh screen 800, and cylinder 400 is connected away from a port of level ground and the discharging opening 220 of feeding warehouse 200 at gravity direction.The barrel hole size of mesh screen 800 arranges according to the needs of actual conditions.
Wherein, in the present embodiment, elastic component 900 is spring.In other embodiments, elastic component 900 can also adopt other to have the parts of elasticity and buffer action.
As shown in Figure 6, it is the structural representation of the separating plate 500 of the coal screen 10 shown in Fig. 1.Separating plate 500 is located on bracing frame 100, and is surrounded on the side of cylinder 400.On separating plate 500, offer fines separating opening 510, fines separating opening 510 is corresponding near the side of level ground with cylinder 400.On separating plate 500, be also provided with the separated slideway 520 of coarse fodder, the separated slideway 520 of coarse fodder is connected with cylinder 400 port near level ground on gravity direction.
