Intermittent discharging type multi-stage screening device for building

Abstract

The invention relates to the technical field of building equipment, in particular to an intermittent discharging type multi-stage screening device for a building. The device comprises a housing, wherein a feeding box is fixedly connected to the top of the housing, a discharging mechanism is arranged at the bottom of the feeding box, a plurality of screening mechanisms are arranged on the lower side of the discharging mechanism, the screening mechanism is connected to the discharging mechanism through a transmission mechanism, and a collecting box is arranged at the bottom of the inner side ofthe housing. According to the device, as the discharging mechanism is arranged, intermittent discharge of the device is achieved as a baffle plate moves repeatedly left and right by means of an incomplete gear and a first spring, so that a condition that the screening efficiency is affected as meshes of a filter screen are blocked due to excessive discharge at one time is avoided. By arranging thetransmission mechanism, a motor drives a transmission bar to rotate, the transmission bar drives a cam to rotate, and under interaction of the cam and a second spring, a placing frame vibrates, so that the sand screening efficiency is improved. By arranging the multiple screening mechanisms, the device can screen various sand of different grain sizes, thereby meeting the demand of different workof people.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to an intermittent feeding type multi-stage screening device for construction. Background technique [0002] Architecture is the general term for buildings and structures, and it is an artificial environment created by people using the material and technological means they have mastered, and using certain scientific laws, feng shui concepts, and aesthetic principles to meet the needs of social life. Building is a kind of space for people to live and use that people use soil, brick, tile, stone, wood; (reinforced concrete, profiles) and other building materials, such as residences, bridges, factories, gymnasiums, caves, water towers, Temples and more. Broadly speaking, landscape and gardens are also part of architecture. In a more general sense, the consciously constructed nests of animals can also be counted as buildings. [0003] Sand is an essential basic raw mat...

Problems solved by technology

Therefore, it is necessary to screen the sand before using the sand. The existing sand screening equipment generally only performs one screening, which cannot meet different work needs. Hole blockage reduces the screening efficiency. Therefore, in view of the above status quo, it is urgent to develop a construction intermittent feeding multi-stage screening device to overcome the deficiencies in current practical applications.
