Concrete preparation device for municipal administration

Abstract

The invention discloses a concrete preparation device for municipal administration. The concrete preparation device comprises a fixing base; supporting columns are connected to the two sides of the bottom of a preparation cylinder separately; the bottoms of the supporting columns are connected to the top of the fixing base; the two sides of the bottom of the preparation cylinder communicate with discharging pipes; spraying pipes are connected to the two sides of the bottom of a fixing plate separately; branch pipes are connected to the bottoms of one sides of the spraying pipes; the bottoms of the branch pipes communicate with water tanks; feed ports are connected to one sides of feeding trays; vibration motors are connected to the middles of the bottoms of the feeding trays through supports; supporting springs are connected to the two sides of the bottoms of the feeding trays separately; sealing covers are connected to the bottoms of through pipes in a threaded mode; inner cavities of the through pipes are provided with top plates; and electric telescopic rods are connected to the bottoms of the top plates. The concrete preparation device has the advantage that the proportion error among gravel, cement and water can be reduced, the problem that the concrete preparation quality can be reduced due to the fact that the proportion error among the gravel, the cement and the water is large can be solved.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a preparation equipment for municipal concrete. Background technique [0002] Concrete refers to the collective name of engineering composite materials that use cementitious materials to cement aggregates into a whole. The term concrete usually refers to the use of cement as cementitious material, sand and stone as aggregate, and water in a certain proportion. Cement concrete obtained by mixing, also known as ordinary concrete, is widely used in civil engineering. Concrete can be traced back to ancient times. The cementitious materials used are clay, lime, gypsum and volcanic ash. [0003] When preparing concrete, sand, cement and water need to be mixed according to a certain ratio. The existing concrete preparation equipment is very troublesome when calculating the weight of sand, cement and water. There is a large error in the ratio between them, which will reduce the quality...
