The front end in the screening feed hopper 16 is provided with a plurality of material distributing plates 18, gaps are arranged among the material distributing plates 18, and the gap distance between the adjacent material distributing plates 18 is larger than the diameter of small-particle-size materials and smaller than the diameter of large-particle-size materials. The tail end of the material distributing plate 18 is provided with a material guiding plate 19, the material guiding plate 19 is arranged in an inverted V shape, and the height of the material guiding plate 19 is higher than that of the material distributing plate 18. Moreover, two material collecting plates 17 are symmetrically arranged on the bottom plates of the screening feed hoppers 16 at two sides of the material guide plate 19, and the material collecting plates 17 are Y-shaped structures. It should be noted that the end of the screen hopper 16 is directly connected to the chute 12.
Further, the lower part of the sieving hopper 16 is provided with legs which are connected to the sieving hopper 16 by springs 23, thus damping the vibration of the sieving hopper.
During concrete implementation, vibrating feeder 20 drives screening feeder hopper 16 and carries out synchronous oscillation, and vibrating feeder 20 will treat that the broken material is sent into in the screening feeder hopper 16, and the interval material of small-size enters into on the bottom plate of screening feeder hopper 16 through the clearance between the branch flitch 18 to flow down under the effect of gravity, until the material along the middle throwing material subassembly of the passageway flow direction counterattack formula breaker between two collection flitchs 17 on.
