Detailed ways

The utility model's waste soil screening device for hydropower station waste dump will be further described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in Figure 1, the utility model hydropower station waste dump muck screening device includes a fixed frame 1. The fixed frame 1 is provided with a muck feeding box 2, a screen plate group, a collection box group, a bottom collection box 9 and a large Shaker 10. The sieve plate group includes a first sieve plate 3 , a second sieve plate 5 and a third sieve plate 7 , and the collection box group includes a first collection box 4 , a second collection box 6 and a third collection box 8 . The above arrangement sequence from top to bottom on the fixed frame 1 is: soil feeding box 2, first screen plate 3, first collection box 4, second screen plate 5, second collection box 6, third screen Board 7, third collection box 8, bottom collection box 9 and large shaker 10.

Among them, as an embodiment, the sieve hole diameters of the first sieve plate 3, the second sieve plate 5, and the third sieve plate 7 decrease sequentially from top to bottom. In this embodiment, the muck is placed on the muck conveyor belt 12 and transported into the muck feeding box 2 through the muck conveyor belt 12. The muck passes through the first sieves with different mesh apertures from top to bottom. Plate 3, the second sieve plate 5, and the third sieve plate 7, thereby achieving separation of muck.

When screening the waste in the waste dump, the utility model's waste screening device in the hydropower station waste site drives the large shaker 10 through the drive motor 11, so that the large shaker 10 makes a reciprocating linear motion, so that the waste moves from top to bottom.
