Description

Technical Field

[0001] The utility model belongs to the technical field of sorting equipment, and in particular relates to a bouncing screen. Background Art

[0002] The working principle of the bouncing screen is mainly to drive the screen plate to perform complex movements through the eccentric shaft to screen materials of different sizes, densities and shapes. In garbage disposal, the application effect of the bouncing screen usually depends on the degree of pre-treatment of the garbage and the adjustment and optimization of the screen itself. This technology can effectively separate 3D materials (such as plastic bottles, wood, masonry, etc.) from light and flat 2D materials (films, paper and cardboard) and fine materials under the screen (sand and food residues).

[0003] In order to prevent materials from bouncing out during the screening process and to facilitate feeding, the existing bouncing screen is generally set in a box with an open top, such as CN 117862006 A, CN104148279A... However, for materials with higher hardness such as sand and gravel aggregates, if the bouncing force is too large, it is easy to cause them to bounce out of the bouncing screen, so the screening effect is limited. Utility Model Content

[0004] Aiming at the problem in the prior art that for materials with relatively high hardness such as sand and gravel aggregates, if the bouncing force is too large, it is easy to cause them to bounce out of the bouncing screen, thus limiting the screening effect, the utility model provides a bouncing screen.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A bouncing screen comprises a base frame, a supporting frame is arranged on the base frame, one end of the supporting frame is hinged to the base frame, and the other end is hinged to a telescopic mechanism, and the telescopic mechanism is connected to the base frame, an eccentric driving system is arranged on the supporting frame, and the eccentric driving system is connected to a plurality of bouncing bridge plates which can move separately, and a bouncing screen cover is detachably connected to the supporting frame, a light material outlet and a heavy material outlet are arranged below the bouncing screen cover, and a feed inlet is arranged above the bouncing screen cover.

[0014] Preferably, each of the bouncing bridge plates is provided with a plurality of feeding holes.

[0015] After adopting this technical solution, fine materials can fall from the bouncing bridge plate through the material holes.
