Automatic detection and alarm method for material shortage of silo and silo discharging device applied to automatic detection and alarm method

Abstract

The invention relates to an automatic detection and alarm method for material shortage of a silo and a silo discharging device applied to the automatic detection and alarm method. The device comprises at least one silo; a first conveying belt which receives and conveys materials of the silo is arranged below the discharging opening of the silo; a material shortage detector for detecting whether material falls or not is mounted at the discharging opening of the silo; a vibrator which vibrates and makes the materials which are attached to the inner wall drop is mounted on the outer wall of the silo; a multi-layer alarm lamp is mounted at the top of the silo; a belt motor of the first conveying belt, the material shortage detector, a vibrating motor of the vibrator and the multi-layer alarm lamp are all electrically connected to a PLC (Programmable Logic Controller); the PLC is electrically with an industrial computer; the industrial computer is electrically connected with a display. When the material shortage happens to the silo, the automatic detection and alarm method can respond automatically; the field scheduling can be based on the signals of the multi-layer alarm lamp; the giving sequence of the feeding of the silo is arranged reasonably; the production efficiency and the sustained stability of production are guaranteed.

Description

technical field [0001] The invention relates to an automatic detection and alarm method for material shortage in a silo and a silo unloading device used therein. Background technique [0002] The silo is an important part of the plant mixing equipment, which undertakes the conveying function of various sand and gravel materials. The batching silo of a set of plant mixing equipment is generally composed of multiple silos, and each type of sand and gravel material needs to be transported with a certain proportion of flow. The process is bound to be affected. SUMMARY OF THE INVENTION [0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an automatic detection and alarm method for material shortage in a silo and a silo unloading device used therefor, which can automatically make corresponding alarm actions when material shortage occurs, greatly reducing the need for Improve production efficiency and ensure product...
