Metering method and device and feeding system with metering device

Abstract

The invention discloses a metering device. The metering device comprises a stocker and weighing devices, and further comprises a conveying machine arranged below the stocker. The conveying machine is used for driving materials to be discharged, and when the reduction value of the weight, weighed by the weighing devices, of materials on the convening machine is equal to the preset weight value, discharging is stopped. When the metering device is applied, discharging is even, impacting is small, adjusting and controlling of discharging are convenient, and the accuracy of the metering device is increased. Materials are conveyed and discharged through the conveying machine, impacting of the following device is small, on one hand, abrasion of the following device is not prone to being caused, and the service life of the following device can be prolonged; on the other hand, splashdown of materials is not prone to occurring during discharging, the influence on the environment is reduced while the metering accuracy is further increased, and the labor intensity of cleaning persons is reduced. Multiple materials can be discharged at the same time, and production efficiency is effectively improved. The invention further discloses a feeding system comprising the metering device and a metering method.

Description

technical field [0001] The present invention relates to the technical field of metering, more specifically, to a metering device, a metering method, and a feeding system including the metering device. Background technique [0002] The weighing scale is an important part of the feeding equipment, and the weighing scale can be used to feed materials according to the preset material weight requirements. The equipment used for the measurement and temporary storage of aggregates (medium stones, small stones, coarse sand, fine sand) in the mixing plant generally adopts electronic weighing scales. [0003] The ground bin metering device in the prior art weighs the weight of the material in the metering hopper through a load cell when the storage hopper discharges material to the metering hopper. When the weight of the material reaches the preset weight value, the cylinder of the storage hopper drives the fan-shaped discharge door to close, and then the weighed material is discharg...
