Embodiment
As shown in figure 1, a kind of existing feeder, include the body 40 of tubular, be provided with charging aperture 41 on body 40, go out
Material mouth 42 and the rotary shaft 9 conveyed to coal dust, blade 44 are provided with rotary shaft 9, the rotating band movable vane piece 44 of rotary shaft 9 is transported
Dynamic, coal dust is delivered to discharging opening 42 by blade 44 from charging aperture 41.One end of rotary shaft 9 can connect force piece 43, other end meeting
Connection is arranged on the bearing block of body 40, is provided with bearing 10 in bearing block, under normal circumstances.Bearing 10 supports rotary shaft 9 same
When do not influence rotary shaft 9 and rotate.
The work of rotary shaft 9 is influenceed to solve the problems, such as that coal dust penetrates into bearing 10, shown in Fig. 2, there is provided one kind is used for feeder
Bearing block, include the body 1 of connection feeder, body 1 can be square or cylinder, and body 1 with feeder with being bonded
Plane, body 1 and feeder poor sealing are avoided, coal dust is dispersed to feeder exterior space, cause environmental pollution.
Axis hole 2 is provided with the plane that body 1 is bonded with feeder, axis hole 2 is used for the rotary shaft 9 for supporting feeder, changed
Yan Zhi, body 1 are provided with the axis hole 2 of the rotary shaft 9 of accommodating feeder.
The bearing 10 for being set in rotary shaft 9 is provided with axis hole 2, bearing 10 rotates freely rotary shaft 9.
Axis hole 2 is provided with the bearing hole 4 of accommodating bearing 10 backwards to one end of feeder, namely for installing the axle of bearing 10
Bearing bore 4.The distance of bearing 10 and coal dust is increased, reduces the coal dust of infiltration bearing 10, while reduce coal dust and passed to bearing 10
The heat passed.
