[0018] The construction waste crushing device provided in this disclosure can achieve the following technical effects:

[0019] This disclosure provides a construction waste crushing device, including a crushing box, a first rotating shaft, a first circular plate, hammers, an impact liner, a second rotating shaft, a second circular plate, a chain, and impact hammers. The crushing box contains construction waste. The first rotating shaft is rotatably mounted on the crushing box along its length and can rotate relative to the crushing box. The first circular plate is mounted on the first rotating shaft and located inside the crushing box, rotating under the drive of the first rotating shaft to support the hammers. The hammers are mounted on the first circular plate along its length and are evenly distributed around the perimeter of the first circular plate, all used to crush the construction waste. The impact liner is installed inside the crushing box and is evenly distributed on the sides of multiple hammers, working in conjunction with the hammers to crush the construction waste. Furthermore, the impact liner prevents the construction waste from directly contacting the inner wall of the crushing box during crushing, reducing wear and damage to the crushing box. The second rotating shaft is rotatably mounted on the crushing box along its length and on both sides along its width. Along the height of the crushing box, both second rotating shafts are located below the first rotating shaft and can rotate relative to the crushing box. Second circular plates are evenly mounted on the two second rotating shafts and rotate under their drive, each supporting the mounting chains. Chains are connected to multiple second circular plates on both sides and evenly distributed around the perimeter of each plate, connecting to the striking hammers. The striking hammers are connected to each chain and are used to crush construction waste. The first rotating shaft and the two second rotating shafts can be controlled to rotate, driving the multiple hammer plates and the multiple striking hammers on both sides to rotate.

[0020] During operation, the first rotating shaft, driven by external force, rotates, which in turn drives the first disc to rotate, and then drives multiple hammers to rotate. Working in conjunction with multiple impact liners, this allows for primary crushing of larger construction waste, breaking it down into smaller volumes. The second rotating shafts on both sides, driven by external force, rotate, which in turn drives multiple second discs on both sides to rotate. This, in turn, drives multiple second chains on both sides to rotate, ultimately driving multiple impact cones on both sides to rotate, performing secondary crushing of the crushed construction waste into smaller volumes, reducing the risk of jamming. Furthermore, the chains installed between the hammers and the discs deform upon contact with the construction waste, further preventing jamming and ensuring optimal crushing results.
