comprises a case (1), a support frame (2) arranged at the bottom of the case (1), a feeding hopper (3) arranged at the top of the case (1) and used for feeding materials, a sieve plate assembly (4) obliquely arranged in the case (1) and positioned at the output end of the feeding hopper (3) and used for sieving the materials into 3D objects, fine objects and 2D objects, a swing mechanism arranged in the case (1) and used for driving the sieve plate assembly (4) to swing in a reciprocating manner, a first discharging hopper (6) arranged at the bottom of the case (1) and positioned on a 3D object channel and used for outputting the 3D objects, a second discharging hopper (7) arranged at the bottom of the case (1) and positioned on the fine object channel and used for outputting the fine objects, and a third discharging hopper (8) arranged at the bottom of the case (1) and positioned on the 2D object channel and used for outputting the 2D objects,
the swing mechanism adopts the swing mechanism of any one of claims 1 to 4.
6. The bounce screen of claim 5,
the machine case (1) is provided with a wind power auxiliary climbing device (9) which is used for generating airflow to drive the 2D object to climb to the 2D object channel along the sieve plate component (4);
a coaming (11) for preventing materials from being thrown to the outside of the case (1) is arranged at the top of the case (1);
and a damping device (12) for damping is arranged between the case (1) and the support frame (2).
7. The bounce screen of claim 5,
the screen plate assembly (4) comprises a screen plate (41) with a screen hole in the middle, a first mounting seat (42) arranged at one end of the screen plate (41) and used for being hinged to a first swing arm (52) of the swing mechanism, and a second mounting seat (43) arranged at the other end of the screen plate (41) and used for being hinged to a second swing arm (54) of the swing mechanism.
8. The bounce screen of claim 7,
the top of the sieve plate (41) is provided with first flanges (44) positioned at two sides of the sieve plate (41), and the top of the first flanges (44) is wavy or toothed, so that the first flanges (44) hook 2D objects to enable the 2D objects to climb along the sieve plate (41);
and second flanges (45) which are positioned at two sides of the sieve plate (41) and used for preventing materials from being thrown are arranged at the bottom of the sieve plate (41).
9. The bounce screen of claim 7,
the two ends of the sieve plate (41) are provided with parting beads (46) for assisting the material to bounce;
and a baffle (47) for distinguishing a screening channel is arranged at the bottom of the screen plate (41).
10. The bounce screen of claim 7,
the sieve plate assemblies (4) are arranged into a plurality of groups, the sieve plate assemblies (4) are arranged in a staggered mode, and a connecting rod mechanism and a crank rocker mechanism of the swing mechanism are respectively arranged in one-to-one correspondence with the sieve plate assemblies (4).
