Furthermore, a plurality of fixing holes are uniformly formed in the fixing strips and used for detachably installing the screen.

Furthermore, one end of the base, which is close to the third screen, is a feed inlet, and one end, which is close to the first screen, is a discharge outlet.

Further, the screen gaps of the first screen, the second screen and the third screen are reduced in sequence.

The utility model has the advantages that:

1. the utility model provides a reciprocating sieve for granule screening usefulness has multiple type screen cloth, can divide the echelon screening according to the granule size to effectively separate out the granule of different diameters.

2. The vibration exciters are arranged in parallel up and down, the upper vibration exciter enables the screen to vibrate in the vertical direction, the lower vibration exciter enables the screen to vibrate in a conical surface rotation mode, the effect of the combined action enables the screen to vibrate in the horizontal direction, and particles with different diameters are sequentially screened from small to large while moving forwards.

3. First screen cloth, second screen cloth and third screen cloth detachable installation design respectively are convenient for change the screen cloth according to actual need, simple structure, and the practicality is strong.
