Weighing device and method

Abstract

The invention relates to the field of metering, and in particular relates to a weighing device and a method, which can improve weighing capacity, increase dosing capacity, satisfy production demands and weigh the weight of materials more accurately at the same time. The weighing device comprises a plurality of discharging devices, a plurality of weighing machines; a plurality of weighing sensors and a controller, wherein a valve for discharging materials is respectively arranged on the plurality of discharging devices; each weighing machine is used for placing the materials discharged by each discharging device; one weighing sensor is arranged on each weighing machine; and the weighing sensors are used for weighing the materials in the weighing machines; and the controller is respectively connected with the valve at each discharging device and each weighing sensor at each weighing machine and is used for simultaneously receiving a plurality of weighing data sent by the plurality of weighing sensors, matching with a preset proportioning of multiple materials according to the plurality of weighing data, and respectively controlling the switch on and off of the valve at each discharging device according to a matched result.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a weighing device and a weighing method. Background technique [0002] With the growing demand of animals and plants for various nutrients, the compound fertilizer industry is developing more and more rapidly. The mixed fertilizer industry mixes various fertilizers according to a predetermined ratio (mostly follow the ratio of the needs of animals and plants for various nutrient elements during the growth process), so as to obtain compound fertilizers that meet the needs of use. In order to make multiple fertilizers meet the predetermined ratio, each fertilizer needs to be weighed separately. [0003] The traditional mixed fertilizer industry generally uses a belt scale as a mixing weighing device. The belt scale is a device that puts the material on the belt, makes the material pass continuously along with the belt, and automatically weighs the material during the passing process. ...

AI Technical Summary

Problems solved by technology

When the mixed fertilizer that needs to be prepared contains several kinds of fertilizers, it is necessary to use a belt scale to weigh several times, which makes the weighing efficiency low, especially when the mixed fertilizer contains dozens or more kinds of fertilizers. The weighing capacity is even lower, which makes the batching capacity low and cannot meet the production needs
