Abstract

The invention discloses a gravel multi-layer screening device for building construction, and belongs to the technical field of buildings. The gravel multi-layer screening device for building construction solves the problem that caked gravel cannot be screened due to the fact that an existing device cannot conduct rolling treatment on the gravel. The gravel multi-layer screening device for buildingconstruction is technically characterized by comprising a shell and a screening cavity, the shell is internally provided with the screening cavity, the screening cavity is internally provided with ascreening assembly, the lower portion of the screening assembly is provided with a driving assembly, the driving assembly is connected with the screening assembly, the top of the screening cavity is provided with a grinding cavity used for grinding the gravel, the grinding cavity is internally provided with a grinding assembly, and a partition plate is fixedly installed in the screening cavity. According to the embodiment of the gravel multi-layer screening device, the grinding assembly is arranged, the gravel in the grinding cavity is ground through the arrangement of the grinding assembly, the problem of low gravel filtering efficiency caused by gravel caking is avoided, and meanwhile, through the arrangement of the screening assembly, multi-level sufficient screening of the gravel is realized.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a sandstone multi-level screening device for construction. Background technique [0002] Sand and gravel are common building materials. During construction, construction sand and gravel with different particle sizes need to be subdivided so that the sand and gravel can be subdivided through the sieve holes. At this stage, ordinary sieves are mainly used for subdivision of sand and gravel. For screening, when in use, the screen is supported on the ground and manually operated by construction personnel, which will not only reduce the screening efficiency, but also increase the workload of construction personnel. [0003] Chinese patent CN208695529U discloses a sand and gravel screening device for building construction, including a tank body, which is characterized in that: the top of the tank body is provided with a feed port, and a screen is installed on the inner wall of the...
