The utility model provides a dust absorption sleeve of dust exhausting fan, includes dust absorption sleeve, pivot and fixed machine sleeve, and the dust absorption sleeve is provided with 1 or 2 inlet scoop, and the inlet scoop aims at coal-winning machine cutting units, passes through the slot block between fixed machine sleeve and the dust absorption sleeve, and the middle part of the continuous department of fixed machine sleeve and dust absorption sleeve is provided with the pivot, and the dust absorption sleeve links to each other with the fan, and the position of inlet scoop still is provided with the reinforcing bar net.
Preferably, the section from the air suction opening to the rotating shaft is cylindrical, and a first bending part is further arranged and is adapted to the position of a cutting drum of the coal mining machine; and a second bending part is arranged at the mounting position of the fixed machine sleeve, which is suitable for the fan.
Preferably, the first bent portion and the second bent portion are provided with a reinforcing rib and a reinforcing plate at positions thereof.
Further preferably, the fixed sleeves are provided with mounting seats matched with the coal mining machine.
Further preferably, the dust collection sleeve is U-shaped, and the air suction openings are formed at two ends of the dust collection sleeve; the middle parts of the fixed machine sleeve and the dust collection sleeve are connected.
A dust removal fan with a dust collection sleeve is provided with the dust collection sleeve, the fan is installed below a hydraulic support, and dust generated by coal cutting of a coal mining machine is discharged into an air return roadway through the dust removal fan.
It is also preferred that the air outlet position of the fan is provided with a dust removal nozzle.
It is still preferred that the dust fall spraying nozzle is provided at the air suction opening of the dust absorption sleeve.
The utility model has the advantages that the dust absorption sleeve provided with the dust removal fan moves along with the cutting part of the coal mining machine, so that dust can be efficiently absorbed, the dust absorption sleeve is more convenient to move due to the rotation fit of the dust absorption sleeve, and the reinforcing mesh is arranged at the position of the air suction port, so that the coal blocks falling from the cutting part of the coal mining machine can be prevented from entering the dust absorption sleeve to cause plugging; in addition, the dust absorption sleeve is provided with one or two air suction openings so as to adapt to a single-drum coal mining machine or a double-drum coal mining machine.
