Large block removing device for bucket wheel machine

Abstract

The invention relates to a large block removing device for a bucket wheel machine. The large block removing device for the bucket wheel machine comprises a bearing support seat assembly, a driving shaft assembly, impellers, a driving device assembly, a plurality of floating moment arms, an outer casing, an elastic automatic sweeping device, a plurality of elastic buffer seat body and an electric control cabinet. The impellers adopted by the large block removing device are arranged on driving shafts in a spiral curve shape, so the driving shafts rotate at a high speed, large blocks can be favorably discharged out, and the sieve passing rate is increased. The elastic automatic sweeping device of the large block removing device can be used for clearing sundries pasted on the impellers in time. When the large blocks are clamped between the adjacent driving shafts, the elastic buffer seat body and the floating moment arms can generate certain displacement, the force balance is damaged, and the clamping is eliminated. The large block removing device adopts the electric control cabinet, and can realize the remote on-site control conversion.

Description

technical field [0001] The invention relates to a bucket wheel machine in the field of loading and unloading machinery, in particular to a bucket wheel machine removing large pieces. Background technique [0002] At present, in order to save production costs, some domestic thermal power plants, steel mills, and coking plants purchase low-quality coal and other fuels. There are many large pieces in the fuel, which pose a threat to equipment such as coal crushers and belts, and accelerate the wear of the hammerhead of the coal crusher. It is easy to scratch the belt, which increases the maintenance workload and capital investment; although some devices are equipped with large block removal devices, they cannot remove the large block from the source, and there are still cases where the cantilever belt of the bucket wheel machine and the trestle belt are scratched . [0003] In view of the defects of the above-mentioned existing bucket wheel machine, through continuous research...
