Movable concrete mixing plant for road and bridge construction

Abstract

The invention discloses a movable concrete mixing plant for road and bridge construction and belongs to the technical field of building construction equipment. The movable concrete mixing plant comprises a stirrer, a material weighing device and a water tank and can be arranged on transportation equipment for transferring; a screw conveyor is arranged between a feeding opening of the stirrer and the material weighing device; the water tank is connected with the stirrer through a water pump and a water inlet pipe with a flowmeter; the material weighing device comprises a material storage hopperof which the bottom is provided with a dynamic weighing and measuring module; the material storage hopper is connected with a turning mechanism; the stirrer comprises a tank body, a stirring shaft and stirring blades; the stirring shaft is vertically arranged in the tank body; a motor for driving the stirring shaft is arranged at the bottom of the tank body; and a plurality of stirring blades areradially arranged at the periphery of the stirring shaft from top to bottom. The dynamic weighing and measuring module weighs all powdery or solid materials; the flowmeter meters the water consumption for stirring; and when the materials are weighed, the turning mechanism and the screw conveyor are started for conveying the materials into the tank body for mechanically stirring and mixing. The movable concrete mixing plant disclosed by the invention can accurately meter the materials, so that the quality of concrete is ensured.

Description

technical field [0001] The invention belongs to the technical field of building construction equipment, in particular to a mobile concrete mixing station for road and bridge construction. Background technique [0002] During the concrete construction process of road and bridge construction, the requirements for concrete mixing and proportioning are very high. Since roads and bridges are long linear structures across regions, the production and construction sites of concrete projects need to be changed frequently. Therefore, concrete production needs to meet the requirements of small volume, high quality and production discontinuity. Most of the concrete production sites in the prior art are fixed and cannot be moved with the project; and before the concrete production, the cement and aggregate are weighed and mixed in advance, and then put into the mixer for mixing. However, manual feeding is used to some extent in the concrete production process, and some materials will be...
