Anti-blocking waste concrete recycling screening device with good crushing effect

Abstract

The invention relates to an anti-blocking waste concrete recycling screening device with the good crushing effect. The anti-blocking waste concrete recycling screening device with the good crushing effect comprises a main body, a feeding pipe, a discharging pipe and screen cloth, and further comprises an unchoking mechanism and two crushing mechanisms. The unchoking mechanism comprises a mobile plate, two mobile assemblies and a plurality of unchoking rods. Each mobile assembly comprises a first motor, a wire spool, a pull wire, a fixed plate and a first spring. Each crushing mechanism comprises a driving assembly and a crushing assembly. Each crushing assembly comprises a connecting block and a crushing plate. Each driving assembly comprises a second motor, an eccentric wheel, a supporting plate, a lifting rod, a second spring and a lantern ring. According to the anti-blocking waste concrete recycling screening device with the good crushing effect, because the unchoking mechanism canbe used for carrying out unchoking work on screen meshes on the screen cloth, it is avoided that the screening effect is affected because the screen meshes are blocked by concrete; and because the crushing mechanisms can be used for carrying out crushing work on concrete chunks, and it is avoided that the screening work cannot be carried out because concrete is large in size.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a recycling and screening device for waste concrete with good crushing effect and anti-clogging. Background technique [0002] The waste concrete recovery and screening device uses sieves with different sieve sizes to separate solid materials according to the required particle size. [0003] After the existing waste concrete recovery and screening device works for a long time, concrete is easy to accumulate in the sieve holes on the screen, which affects the screening effect of the screen. Not only that, but the existing waste concrete recovery and screening device is performing screening work Previously, it was necessary to artificially pulverize large agglomerated concrete, which increased the workload of the staff, and the pulverization effect was poor, which reduced the practicability of the waste concrete recycling and screening device.
