Gravel multi-stage screening device for building construction

Abstract

The invention discloses a gravel multi-stage screening device for building construction. The gravel multi-stage screening device for building construction structurally comprises a bottom plate, a shell, a vibration device, a vibration cavity, a supporting column, a conveying belt, a guide plate, a first hopper, a first through hole, an opening and closing device, a stone outlet, a discharging plate, a sand aggregate outlet, a discharging trolley, a second hopper, a first supporting plate, a partition plate, a second supporting plate, a second through hole, a discharging opening, a third through hole and a sliding groove; the bottom plate is vertically mounted at the bottom of the shell through a welding connection manner. According to the gravel multi-stage screening device for building construction, the vibration device is arranged on a left side plate of a screening frame, a motor in the vibration device moves at the high speed, the rack is driven to do reciprocated motion, under theeffect of the rack, the screening frame does the left and right reciprocating motion, shaking between gravel on a screen net can be accelerated, separation between the gravel can be accelerated, stone and sand aggregate are discharged from different outlets, the separation manner is efficient, operation is easy and convenient.

Description

technical field [0001] The invention relates to a sandstone multistage screening device for building construction, which belongs to the field of sandstone multistage screening equipment for building 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. During the construction of construction projects, after the sand is transported from the river or other places, it often contains a lot of large particles of gravel, etc., whi...
