Detailed Description

As shown in fig. 1 and 2, a roadway coal dust cleaning conveyor comprises a frame 1, a power source 2, a coupling 3, a driving shaft 4, a flexible shaftless helical blade 5, a discharging pipe trough 6, a rubber hose 8 and a self-excited vibration type feeding head 10; wherein, the self-excited vibration type feeding head 10 consists of a connecting pipe 12, a connecting rod 13, an outer sleeve 15, an inner end transparent cover 14, an end shaft 19, an eccentric block 16, a flat key 17 and an outer end transparent cover 18; one end of the flexible shaftless helical blade 5 is fixedly connected with an end shaft 19 of the self-excited vibration type feeding head 10 by a U-shaped clamp 21, and the other end is fixedly connected with the driving shaft 4 by a U-shaped clamp 22; the rubber hose 8 is sleeved outside the flexible shaftless helical blade 5, and two ends of the rubber hose are fixedly connected with the discharge pipe chute 6 and a connecting pipe 12 of a self-excited vibration type feeding head 10 by a hoop 7 and a hoop 9 respectively.

The power source 2 can be a power device such as an electric motor, a hydraulic motor or a pneumatic motor, the power source 2 is connected with the driving shaft 4 through the coupling 3, and the driving shaft 4 penetrates into the discharging pipe chute 6 through a hole on the side wall of the discharging pipe chute 6; the power source 2 and the discharge pipe groove 6 are respectively fixed on the frame 1.

The connecting pipe 12 and the outer sleeve 15 of the self-excited vibration type feeding head 10 are fixedly connected by a connecting rod 13; the end part of the outer sleeve 15 close to the side of the connecting pipe 12 is fixedly connected with an inner end transparent cover 14, and the end part of the other side is fixedly connected with an outer end transparent cover 18; the eccentric block 16 is fixedly connected to the end shaft 19 by a flat key 17; an end shaft 19 is supported on the inner end transparent cover 14 and the outer end transparent cover 18.
