When the material falls, it passes through the separation cover 21, and the jet fan 222 in the jet cover 221 is started, thereby generating wind force to blow the garbage bags mixed in the material, such as plastic bags, onto the bag hanging part 233. The jet cover 221 can realize its own disassembly and assembly through the mounting bolts 224 and the mounting bolts 224. The position of the garbage bag is fixed by the hanging needles 2332 densely distributed on the surface of the fixed needle strip 2331, and then the garbage bag attached to the hanging needle 2332 is moved under the drive of the conveyor belt 232. When the fixed needle strip 2331 moves to a suitable position, the signal receiver 2 337 receives the signal from the signal transmitter, thereby starting the exhaust pump 23353 to discharge the gas in the shrink airbag 23351, and then using the shrink airbag 23351 to move the synchronous plate 2334, and then shrink the hanging needle 2332 through the movable hole 23311 to fix the inside of the needle plate 2331. Similarly, the air pump 23352 and the connecting pipe 23354 can inject gas into the shrink airbag 23351 to achieve reset. After the hanging needle 2332 is retracted into the fixed needle plate 2331, the garbage bag falls outside the separation cover 21 under the action of gravity and the scraper 2333. At the same time, the bottom slope of the protective cover 231 can prevent the accumulation of fragments; the material falls into the crushing mechanism 3 for crushing.

[0045] In summary, the construction waste crushing and recycling device provided in this embodiment loads the material through the loading mechanism 1, so that the material is moved to the top of the crushing mechanism 3, and falls and passes through the separation mechanism 3 to the crushing mechanism 3; the material to be processed is separated by the separation mechanism 3 to separate the garbage bags mixed in the material to be processed to the outside, and the material in the material to be processed continues to fall into the crushing mechanism 3 for crushing, which can realize the automatic separation of garbage bags in construction materials, reduce labor costs and eliminate safety hazards, and solve the problem that the existing construction waste is manually selected from plastic bags in front of the crusher, which increases labor costs and has certain safety hazards next to the crusher, which can easily cause workers to be injured by flying debris.

[0046] Furthermore, the garbage bag is hung by the hanging needle 2332 and transferred to the outside of the separation cover 21, and the hanging needle 2332 can be extended and retracted on the fixed needle plate 2331, so that the garbage bag hung thereon is convenient to fall due to gravity on the outside of the separation cover 21, further improving the practicality of the device.
