Abstract

The invention provides a method for controlling a bucket-wheel reclaiming machine with material measurement and calculation, comprising the steps as follows: a current detection module (2) detects corresponding weak alternating current voltage signal from the line current of a bucket-wheel motor current circuit (1); the weak alternating current voltage signal is transmitted to a current / voltage signal conversion module (3) so that the rectification, voltage-stabilization and amplification treatment of the signal is carried out; the voltage signal which is processed by rectification, voltage-stabilization and amplification is input to a reclaiming automatic control module (6) which controls the actions of a revolving mechanism (19) and a truck feeding mechanism (20) according to the change of the voltage signal; and the actions of the revolving mechanism (19) and the truck feeding mechanism (20) cause the bucket-wheel motor current circuit (1) to change. The invention also relates to a reclaiming automatic control device. As the reclaiming automatic control method of the invention is adopted and the reclaiming automatic control device of the invention is installed, the functions of automatic control of reclaiming, flux display and alarming when the flux exceeds the arranged value can be quickly and simply realized at low cost.

Description

technical field

[0001] The invention relates to a control device and a control method for a bucket-wheel reclaimer, in particular to a control device and a control method for a cantilever-type bucket-wheel reclaimer. The cantilever-type bucket-wheel reclaimer is equipped with material measurement. Background technique

[0002] The bucket wheel stacker-reclaimer is mainly used for storage, excavation and equalization of bulk materials, and it plays an important role as the core of the continuous bulk material loading and unloading system. It can not only take materials away from the storage yard through the rotating bucket wheel, but also stack the materials to the storage yard by reversely running the bucket arm belt conveyor, which belongs to the continuous and efficient combination of stacking and taking. Loading and unloading equipment. Stackers and reclaimers are widely used in large bulk cargo ports, coal storage yards of thermal power plants, large earthwork engineeri...
