Material conveying device for sand making from building solid waste garbage

Abstract

The invention relates to the technical field of material conveying equipment, and discloses a material conveying device for sand making from building solid waste garbage. The material conveying device comprises a fixed support, supporting main shafts I are fixedly installed on the two sides of the top of the fixed support through a set of connecting fixing plate correspondingly, the two sets of supporting main shafts I are in transmission connection through a material conveying belt, the two sides of the top end of the fixed support are each fixedly provided with a set of supporting main shaft II, the two sets of supporting main shafts II are in transmission connection through an extrusion air bag, and the supporting main shafts I and the supporting main shafts II are in transmission connection through a transmission gear set. According to the material conveying device for sand making from the building solid waste garbage, the extrusion air bag is arranged, when the material conveying belt is used for conveying the building garbage, the building garbage in various shapes and sizes can be extruded on the material conveying belt through the elasticity of the extrusion air bag so as to extrude and fix the building garbage on the material conveying belt, it is effectively ensured that the circumstances of slipping and rolling are not prone to occurring in the conveying process, and the stability and the safety are high.

Description

technical field [0001] The invention relates to the technical field of material conveying equipment, in particular to a conveying device for sand making from construction solid waste. Background technique [0002] Construction waste is an important part of urban waste, and because of the waste concrete and masonry structures contained in it, it is difficult to be treated and incinerated for secondary use like domestic waste. For construction waste, It is crushed, graded and mixed according to a certain proportion to form a concrete aggregate structure, which can be used in engineering construction instead of natural sand and gravel aggregate, which can not only form secondary utilization of construction waste, but also effectively avoid its harmful The pollution problems caused by water, soil and atmospheric environment have become an important development trend of construction waste treatment. [0003] Among them, transportation is an important part in the process of crush...

AI Technical Summary

Problems solved by technology

[0007] The invention provides a conveying device for sand making of construction solid waste, which has the advantages of small floor space, large drop in conveyable height, and no loosening and rolling of construction waste on the conveyor belt due to slipping of construction waste. The advantages of safety and reliability solve the serious limitation of the existing belt conveyor mechanism on the conveying height of materials. In order to improve the conveying height of materials, it is necessary to continuously extend the length of the conveyor belt to reduce its slope. size, which in turn causes the existing belt conveying mechanism to occupy a large area and require high power for the driving equipment. Moreover, construction waste is different from ordinary materials, and the difference between its volume, weight and shape is relatively large. Large, in the process of transporting it to a certain height by the belt conveyor mechanism for crushing, especially some construction waste with a cubic structure, it is very easy to cause the construction waste on it to loosen and roll due to slipping
