Working method of a bucket wheel stacker and reclaimer

Abstract

The invention discloses a working method of a bucket wheel stacker-reclaimer. The bucket wheel stacker-reclaimer comprises a portal frame, a pulley, a steel wire rope, a counterweight, a counterweightarm, a counterweight driving cylinder, a base, trundles, a round base, a pitching mechanism, a crawling ladder, a driver cabin, a rotation mechanism, a bucket wheel, a motor frame, a sliding member,a sliding groove, a storage type flattening rod, a conveyor belt, a bracket, a flattening plate and a flattening motor; the bucket wheel comprises a wheel bucket, a wheel bucket frame, spokes, a rotating shank and a rotating ring; the wheel bucket comprises a large wheel bucket, a small wheel bucket, gear teeth and a hoop; and the hoop comprises a main body layer and a sealing layer. The working method comprises a material reclaiming preparation method, a digging method, an adjustment method and a maintenance method. The material reclaiming preparation method comprises the steps that the bracket is lifted by the pitching mechanism to form a 30-degree included angle with respect to the horizontal direction, so that the counterweight arm is lifted by the counterweight driving cylinder to form a 30-degree included angle with respect to the horizontal direction; and the bucket wheel stacker-reclaimer is moved to the position directly above stacked materials, and the bracket and the counterweight arm are enabled to fall and start to dig materials.

Description

technical field [0001] The invention relates to the fields related to conveyors and bulk material transportation, in particular to a working method of a bucket wheel stacker and reclaimer. Background technique [0002] With the development of science and technology and economic development, the transportation of materials is becoming more and more frequent. At present, the transportation of existing bulk materials such as coal, iron ore, grain, gravel, etc. is generally realized by conveying machinery. Commonly used machinery includes long-heavy machines, bucket wheel stackers, belt conveyors, and turntable conveyors. Machines, etc., through which the materials are transported to the destination to achieve normal industrial production. The material transportation process includes multiple links, among which the equipment that excavates and transports materials from the stockyard to the next link includes bucket wheel stackers and reclaimers. The bucket wheel stacker and re...

AI Technical Summary

Problems solved by technology

However, manual leveling endangers the health of workers and has potential safety hazards. The baffle plate is not effective in overcoming heavy loads, and the problem of collapse cannot be completely avoided by inclined excavation.

[0006] 3. In the specific excavation process of the bucket wheel in the prior art, it will face the problem that the bottom material or corner material cannot be effectively excavated. The relatively small volume of the material is not suitable for the size of the bucket wheel and the excavation circumference, and the bucket wheel is not suitable for the design. Too small, affecting mining efficiency

[0007] 4. The wheel buckets in the prior art are basically completely fixed and cannot be flexibly adapted to various excavation occasions

[0008] 5. The bucket wheels in the prior art are basically completely fixed and cannot be flexibly adapted to various excavation occasions

[0009] 6. The cockpit of the bucket-wheel stacker-reclaimer in the prior art is set on the slewing platform, but it is difficult to have a good view due to its low position

[0010] 7. The counterweight of the bucket-wheel stacker-reclaimer in the prior art is fixed, which cannot achieve dynamic balance with the movable bucket wheel
