Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a highly efficient sand and gravel filtering device for construction engineering. Background Art

[0002] Construction engineering refers to the process of designing, building, maintaining and improving buildings, structures and infrastructure. This field covers the construction and management of various structures from residential and commercial buildings to infrastructure projects such as bridges, roads and pipelines. Sand and gravel are often used in the construction process. Sand and gravel are often mixed with impurities such as large stones or long branches, so sand and gravel need to be filtered. At this time, sand and gravel filtering devices are needed to quickly filter sand and gravel.

[0003] An efficient sand and gravel filtering device for construction projects disclosed in the Chinese utility model patent application disclosure CN114308623B, through the combined action of a shaking mechanism, a rotating mechanism and a breaking mechanism, allows workers to pour sand and gravel into a feed frame, and then intermittently squeeze the first slide bar through the convex block, so that the three shaking bars move left and right, and the agglomerated sand and gravel are easily broken up, thereby overcoming the problem that the existing filtering devices cannot handle agglomerated sand and gravel. However, the sand and gravel filtering device has low flexibility in use, and the branches and debris after filtering remain inside the device, which is not convenient for quick cleaning. Long-term use will cause internal blockage, thereby affecting the stability of the sand and gravel filtering device in subsequent use. Utility Model Content
