Mobile concrete mixing plant for road and bridge construction

Abstract

The invention discloses a mobile concrete mixing station for road and bridge construction, which belongs to the technical field of building construction equipment, and includes a mixer, a material weighing device and a water tank, which can be placed on the transportation equipment for transfer, and the material feeding port of the mixer is connected with the material weighing A screw conveyor is arranged between the devices, and the water tank is connected to the mixer through a water pump and an inlet pipe with a flow meter. The material weighing device includes a storage hopper with a dynamic weighing and metering module at the bottom, and the storage hopper is connected to the turning mechanism; the mixer includes Tank body, stirring shaft and stirring blades, the stirring shaft is vertically arranged in the tank body, the motor driving the stirring shaft is arranged at the bottom of the tank body, and a plurality of stirring blades are radially arranged around the stirring shaft from top to bottom. The dynamic weighing and measuring module weighs various powdery or solid materials, and the flow meter measures the water consumption for mixing; when the materials are weighed, the turning mechanism and the screw conveyor are started to transport the materials to the tank for mechanical stirring and mixing. The material measurement of the invention is accurate, and the concrete quality is guaranteed.

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...
