When the conveyor belt transports sand and gravel into the water body of the filter pool, the wood chips, plastic paper and beverage bottles in the sand and gravel are affected by buoyancy and float or suspend on the water surface or in the water body. The sand and gravel continue to be transferred with the conveyor belt due to its large mass, thereby realizing the separation of the impurities in the sand and gravel from the sand and gravel.

[0013] Compared with the prior art, the environmentally friendly sand and gravel fine screening device provided by the utility model has the following beneficial effects:
[0014] 1. When screening sand and gravel, the sand and gravel breaking component in the funnel will break up the dumped sand and gravel, so that it will be evenly distributed and fall on the sand and gravel screen plate, which can screen the sand and gravel more fully and carefully. With the reciprocating push and pull of the sand and gravel screen plate, the stones in the sand and gravel will be screened out, and the fine sand will fall to the lower end of the mounting frame through the sand and gravel screen plate.

While the push-pull plate swings, the sector-shaped half teeth on its lower surface mesh with and drive the transmission rack, causing the rack to slide back and forth in the guiding frame. A U-shaped plate fixedly installed at one end of the rack is fixedly connected to the sand and gravel sieve plate, thus achieving the effect of driving the sand and gravel sieve plate to reciprocally screen the sand and gravel.
[0017] 3. While the motor drives the connecting column to rotate, the connecting column also drives the rotating column to rotate together through the second transmission belt sleeved on its outer surface. The rotating column drives the dispersing rod to rotate in the funnel, agitating the sand and gravel poured into the funnel and breaking up the sand and gravel clumped together. The broken-up sand and gravel are evenly distributed and fall on the sand and gravel sieve plate, so that the sand and gravel can be screened more fully and meticulously.
