Description

Technical Field

[0001] The present application relates to the technical field of concrete recycling, and in particular to a concrete crushing device with a separation function. Background Art

[0002] Concrete is a general term for engineering composite materials that are made of aggregates bonded together by cementitious materials. The term concrete usually refers to cement concrete that is made by mixing cement as a cementitious material, sand and stone as aggregates and water in a certain proportion. It is widely used in construction projects, and waste concrete and waste bricks and stones generated in construction projects are also common construction waste. In order to save resource waste, concrete crushing equipment is generally used to recycle and crush waste concrete blocks to produce coarse and fine aggregates for reuse.

[0003] For example, the Chinese utility model patent with publication number "CN219024586U" discloses a recycled concrete crushing and separation device, which crushes and scatters the concrete material by rotating the stirring blades inside the box. The scattered concrete material will fall down to the surface of the filter plate below and be filtered by the filter holes on the surface of the filter plate. The filter holes will drop small concrete particles smaller than their area, and intercept concrete blocks that are larger than the filter holes and need to be crushed for the second time, and send the small concrete particles that fall from the filter plate surface into the collection box, so that the staff only needs to continue to pour the concrete blocks in the collection box into the feed port for secondary crushing, and the concrete can be automatically separated.

[0004] However, in the above patent, although the structure of the prior art can realize the screening and secondary crushing of broken concrete, in the actual use of such devices, workers are often required to manually lift and place the collection box to complete the secondary crushing operation of unqualified concrete small materials. This process is time-consuming and laborious for the workers to operate, and it is easy to cause the collection box to fall off during lifting and placing, causing personal danger to the workers. At the same time, the concrete blocks that fall into the collection box are generally mixed with some steel waste, which requires manual picking by the workers for recycling, but the efficiency of manual picking by the workers is low.
