Feeding device for concrete mixing

Abstract

The invention discloses a feeding device for concrete mixing, and relates to the technical field of building material processing. The feeding device for concrete mixing comprises a supporting frame, and two rotating shafts are rotationally mounted at the top of the supporting frame. According to the feeding device for concrete mixing, a gap between a push rod and a fixing rod can block large stones in concrete raw materials, small stones can penetrate through the gap and then are driven by a conveying belt to ascend under the action of an auxiliary screening mechanism, and the push rod can move under the action of a lifting mechanism and a fixing shaft; the push rod moves to push the large stones between the push rod and the fixing rod, the push effect enables the large stones to rise and endows the large stones with certain kinetic energy, and the kinetic energy enables the large stones to be separated from the push rod and the fixing rod, then roll over on the surfaces of the small stones and penetrate through the auxiliary screening mechanism; and the small stones can always rise under the pushing action of the auxiliary screening mechanism, so that accurate screening of the large and small stones in the concrete raw materials is realized.

Description

technical field [0001] The invention relates to the technical field of building material processing, in particular to a feeding device for concrete mixing. Background technique [0002] Concrete, abbreviated as "concrete": refers to a general term for engineering composite materials that are cemented into a whole by cementing materials. The term concrete usually refers to cement concrete as cementitious material, sand and stone as aggregate; it is mixed with water (which may contain admixtures and admixtures) in a certain proportion, and the cement concrete obtained by stirring is also called ordinary concrete. Concrete, which is widely used in civil engineering. [0003] The stones in the existing concrete raw materials will be processed with similar volumes. However, during the stacking process of the existing concrete raw materials, large foreign stones may be mixed inside the stones. These stones will not only affect the performance of the concrete. The quality of the ...

[0003] The stones in the existing concrete raw materials will be processed with similar volumes. However, during the stacking process of the existing concrete raw materials, there may be foreign large stones mixed inside the stones. These stones will not only affect the quality of the concrete. quality, it may also cause damage to the concrete mixing device. The existing screening method is to directly screen stones of different sizes through a screen. Stones will also be sifted and grouped into large stones, which doesn't work well
