Combined metering device and combined metering method thereof

Abstract

The invention discloses a combined metering device which comprises a main vibration disk, a plurality of material processing units, a material collection mechanism and a central processing unit, wherein the main vibration disk is arranged on the upper part of the middle seat of a main body; the material processing units are arranged on the circumstance of the middle seat of a main body at equal interval; the material collection mechanism is configured below the material processing units and comprises an assembled chute and a baiting disk; the central processing unit controls the relevant action of the combined metering device; each material processing unit is correspondingly provided with a wire vibration disk, a buffer bucket and a weighting bucket provided with two weighting bunkers; each material processing unit is also provided with a weighting sensor; the weighting sensor is connected with the weighting hopper and the central processing unit; each material processing unit is also provided with an unit processor; the weighting sensor sends obtained information to the unit processor; and the information is sent to the central processing unit after being primarily processed by the unit processor. The invention also discloses a combined metering method which can improve the precision of combined metering.

Description

technical field [0001] The invention relates to the field of metering and weighing, in particular to a combined metering device and a combined metering method. Background technique [0002] The combined metering and discharging process of the combined metering device is a rapid and uninterrupted process. When the material to be weighed has residues such as sticky material in the weighing hopper, it will not only affect the actual weighing and discharging weight of the current time, but also affect the subsequent series of combined metering and discharging weights, resulting in the actual weight of the discharging material being too small, seriously affect the weighing accuracy. Therefore, the zero-setting operation is particularly important in the application of combined metering devices. [0003] A common combined metering device refers to a weighing device composed of multiple material processing units with independent feeding and discharging structures. Each material pr...

Problems solved by technology

[0006] Disadvantage: Such a zero-setting method will directly reduce the weight values ​​of the two participating combined discharges, greatly reducing the combined measurement accuracy;

[0008] Defect: The two silos are emptied in two material processing cycles and the material in one of the weighing silos is forced to participate in combined discharge, which will extend the impact to the actual discharge weight value of at least 3 material processing cycles, seriously affecting the combination Measurement accuracy
