Specifically, when the dusty air stream flows into the branch pipe 42, the flowing air entrains the soot particles at the free end of the branch pipe 42, and the soot particles are carried into the dust suction pipe 4 to form the dusty air stream.
S4: the dust removal assembly 3 separates and stores the smut particles in the dusty gas stream from the air. Specifically, under the drive of fan 5, dusty air current flows through dust removal component 3, and when dusty air current was flowing through dust removal component 3, the coal dust granule in the dusty air current was separated and was stored by dust removal component 3 to improve the cleanliness factor of the air current of fan 5 of flowing through, avoided the dusty air current that contains a large amount of coal dust to pollute the environment of ground conveying roadway mouth department.
S5: the coal dust particles stored in the dust removal assembly 3 are mixed into the coal storage bin 1. Specifically, the coal dust particles are stored in the dust removal component 3 in a standing mode to reduce dust, and when a set amount of coal dust particles are stored in the dust removal component 3, the coal dust particles stored in the dust removal component 3 are discharged into the coal storage bin 1 to be recycled.

s3: the free end of the branch pipeline is close to the coal dust, and the air near the free end of the branch pipeline and the coal dust are pumped into the dust absorption pipeline by negative pressure in the dust absorption pipeline to form dust-containing airflow;
s4: the dust removal assembly separates and stores coal dust particles in the dusty airflow from air;
s5: and mixing the coal dust particles stored in the dust removal assembly into the coal storage bin.
