Description

Technical Field

[0001] The utility model relates to the technical field of concrete raw material processing, in particular to concrete raw material crushing and screening equipment. Background Art

[0002] Concrete aggregate refers to the granular loose material that plays a role of skeleton or filling in concrete. It is a part of the raw materials of concrete. It is divided into coarse aggregate and fine aggregate. Coarse aggregate refers to pebbles, crushed stones, etc., and fine aggregate refers to natural sand, artificial sand, etc. Aggregates are mostly obtained by crushing larger rocks.

[0003] After searching, it was found that the Chinese patent with publication number CN218459645U disclosed a concrete raw material crushing and screening equipment. In this document, a filter structure is installed in the assembly bin body. The filter structure is composed of a plurality of staggered first support rods and second support rods. The second support rod adopts a plug-in structure design. By controlling the number of second support rods penetrating into the filter plate, the size of the filter holes can be adjusted to suit different types of concrete materials. Although the filter structure can adjust the size of the filter holes, the adjustment method requires controlling the number of second support rods installed, and the number of installations needs to be repeatedly adjusted according to different types of concrete materials. It is not possible to install a matching number of second support rods in the filter structure at one time to adapt to different types of concrete materials, which makes it inconvenient to adjust the size of the filter holes. For this reason, we propose a concrete raw material crushing and screening equipment. Utility Model Content
