Abstract

The invention discloses a material metering device, relates to the technical field of measurement, and solves the technical problems of the prior art that overshoot is large and the valve is easy to damage. The material metering device comprises a metering container, a support and a controller, wherein the metering container is arranged on the support, a feeding channel of the metering container is provided with a first valve, and the first valve is used for controlling the conduction area of the feeding channel of the metering container; a weighing sensor is arranged between the metering container and the support, and the weighing sensor is used for real-time metering the weight value of the metering container; the controller is electrically connected with the weighing sensor through a line or a wireless signal transmit-receive unit; and the controller is used for obtaining the weight value of the metering container, and can control the conduction area of the feeding channel of the metering container through adjusting the size of the opening of a first valve according to a corresponding relation between the prestored conduction area and the weight value of the metering container. The material metering device provided by the invention is used for improving the metering accuracy of the admixture metering container.

Description

technical field [0001] The invention relates to the technical field of metering, in particular to a material metering device. Background technique [0002] Admixture is a powdery mineral that can be added to improve the performance of concrete in order to improve concrete performance, save water, adjust the strength level of concrete, and can be added during concrete mixing. It generally refers to powder such as mineral powder or fly ash. [0003] figure 1 A traditional concrete batching plant admixture metering device is schematically shown. Such as figure 1 as shown, figure 1 The illustrated screw conveyor 120 is a tubular conveyor that pushes material (the material is an admixture) through rotating screw blades for screw conveying. The admixture is stored in the powder silo 6, the manual butterfly valve is opened, and the admixture is transported to the powder metering hopper through the screw conveyor 120. When the metering value is reached, the sensor transmits an a...
