Abstract

The invention discloses a building sand stone screening device, and relates to the technical field of building construction machines. A fixing frame is included and fixedly provided with a screening groove. An incomplete gear is rotationally arranged on the fixing frame and is in driving connection with a reciprocating pushing mechanism for transmission of vertical lifting of a sieve plate. Through an arranged forward and reverse rotation mechanism, the vertical reciprocating type moving effect can be achieved on a threaded sleeve I, the threaded sleeve I achieves the purpose that a sliding block drives a vertical plate to transversely reciprocate through an arranged traction mechanism, accordingly, an overturning mechanism transversely reciprocates, the overturning effect on sand stone atdifferent positions in the screening groove is achieved, and the sieve plate is promoted to sufficiently screen sand stone. Through the arranged reciprocating pushing mechanism, a threaded sleeve IIcan be driven to vertically reciprocate, under the thread meshing action of a threaded rod, the sieve plate vertically ascends and descends in a reciprocating manner while the sieve plate rotates, sufficient rotating dispersing and vibrating of the sand stone on the sieve plate are promoted, and the sand stone screening efficiency is obviously improved.

Description

technical field [0001] The invention relates to the technical field of building construction machinery, in particular to a sand and gravel screening device for construction. Background technique [0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. It includes basic engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where the construction works is called "construction site" or "construction site", also called construction site. [0003] The authorized notification number is CN206392400 U patent discloses a kind of sand and gravel screening equipment, this kind of sand and gravel screening equipment is provided with material guide plate be...
