Abstract

The invention provides a sand aggregate bucket elevator hopper control system and control method and relates to a hopper control system and control method. Through the sand aggregate bucket elevator hopper control system and control method, the problems that aggregates accumulated at the bottom of a machine case of an existing sand aggregate conveying bucket elevator damages a hopper, the maintenance cost of equipment is increased, the maintenance time of the equipment is prolonged, and the running efficiency of a production line is reduced can be solved. The sand aggregate bucket elevator hopper control system is composed of a bucket elevator, a collection hopper, a feed belt conveyor, a return belt conveyor and a PLC. The collection hopper is internally provided with a first material level gage and a second material level gage. The sand aggregate bucket elevator hopper control system can protect the hopper of the bucket elevator against abrasion, prolongs the service life of the equipment and is suitable for controlling the hopper of the bucket elevator.

Description

technical field [0001] The invention relates to a hopper control system and a control method. Background technique [0002] At present, the bucket elevator is used for lifting and conveying sand and gravel aggregates. Since there is a certain distance between the hopper of the bucket elevator and the casing, the aggregate that does not enter the hopper of the elevator will fall and accumulate for a long time. At the bottom of the bucket elevator casing, after the bucket elevator has been used for a long time, a large amount of accumulated aggregate will have contact friction with the bucket inside the bucket elevator. . The common treatment method is to stop the production line, replace the new hopper, and clean the aggregate accumulation at the bottom of the elevator. [0003] To sum up, the accumulated aggregates at the bottom of the casing of the existing bucket elevator for sand and gravel aggregate transportation will cause damage to the hopper, increase the maintenan...
