Batching device with crushing and screening functions for concrete production

Abstract

The invention relates to a batching device with crushing and screening functions for concrete production, in particular to the technical field of concrete production equipment. The batching device comprises a first support, a second support, a screening channel, a first crushing rotating wheel set, a second crushing rotating wheel set, a third crushing rotating wheel set, a transmission mechanismand a batching mechanism; and a first sorting area is arranged between the first crushing rotating wheel set and the second crushing rotating wheel set, a second sorting area is arranged between the second crushing rotating wheel set and the third crushing rotating wheel set, a third sorting area is arranged between the third crushing rotating wheel set and a first discharging opening, and a firstscreen, a second screen and a third screen are correspondingly arranged at the bottom of the first sorting area, the bottom of the second sorting area and the bottom of the third sorting area respectively. Crushing and screening of production raw materials of different particle sizes can be achieved at a time to mix and produce concrete of different specifications, the production process is simplified, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of concrete production equipment, in particular to a batching device for concrete production with the function of crushing and screening. Background technique [0002] Concrete, referred to as "concrete" for short: refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. [0003] In the production process of concrete, it is necessary to use raw materials of different particle sizes (such as stones) to achieve batching according to different needs to produce concrete of different specifications. The existing operation method is to...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a batching device for concrete production with the function of crushing and screening, which overcomes the existing operation method of producing concrete with different specifications, which is to place the production raw materials in a crusher for crushing and then transfer them to a screening machine for screening. The production raw materials of different particle sizes are screened out, and then the production raw materials of different particle sizes are put into each batching box to realize mixing. The process is extremely complicated and cumbersome, and requires huge manpower and material resources.
