Embodiment
As shown in figure 1, a kind of existing feeder, includes being provided with charging aperture 41 on the body 40 of tubular, body 40, goes out
Blade 44 is provided with material mouth 42 and the rotary shaft 9 conveyed to coal dust, rotary shaft 9, rotary shaft 9 rotarily drives blade 44 and 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
Connect setting is provided with bearing 10 in bearing block, under normal circumstances in the bearing block of body 40.The support of bearing 10 rotary shaft 9 is same
When do not influence rotary shaft 9 to rotate.
The problem of influence rotary shaft 9 of bearing 10 works is penetrated into solve coal dust, is used for feeder there is provided one kind shown in Fig. 2
Bearing block, include the body 1 of connection feeder, body 1 can be square or cylinder, and body 1, which has, fits with feeder
Plane, it is to avoid body 1 and feeder poor sealing, makes coal dust disperse to feeder exterior space, causes environmental pollution.
Axis hole 2 is provided with the plane that body 1 is fitted with feeder, axis hole 2 is used for the rotary shaft 9 for supporting feeder, changed
Yan Zhi, body 1 is 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.
One end of the dorsad feeder of axis hole 2 is provided with the bearing hole 4 of accommodating bearing 10, namely for installing the axle of bearing 10
Bearing bore 4.The distance of bearing 10 and coal dust is increased, the coal dust of infiltration bearing 10 is reduced, passed while reducing coal dust to bearing 10
The heat passed.
Meanwhile, the internal diameter of bearing hole 4 is more than the internal diameter of axis hole 2, fixes bearing 10, it is to avoid bearing 10 is along rotary shaft 9
Axis direction vibration.
Body 1 is also provided with covering the closing cap 3 of axis hole 2, it is to avoid external dust produces influence to the operating of bearing 10.
The edge of closing cap 3 is provided with the through hole for installation bolt, and closing cap 3 and body 1 are connected through a screw thread mode and connected.
Closing cap 3 can set the annular protrusion 31 of extension in oriented bearing hole 4, the end face of annular protrusion 31 and bearing 10
Edge is abutted, and can be facilitated and be pressed bearing 10 in people's bearing hole 4.
Only reserved between the inner surface of axis hole 2 and the radially-outer surface of rotary shaft 9 and the activity of axis hole 2 is placed on rotary shaft 9
Small gaps, the gap is 1~1.5mm, and coal dust inlet is few.
Further, first axle 91 is set towards one end of body 1 in rotary shaft 9, first axle 91 is stretched into axis hole 2
Interior, end face and the body 1 of rotary shaft 9 only retain 1mm or so gap, then are formed between rotary shaft 9, first axle 91 and body 1
One labyrinth, coal dust is hardly entered in bearing 10.
As the further expansion of above scheme, the hole wall of axis hole 2 can be provided with the first annular groove 5 for revolving around it axle 9,

It is arranged between the annular groove 5 of bearing hole 4 and first.On the one hand barrier chip penetrates into bearing 10 to sealing ring, on the other hand avoids bearing
10 lubricant grease leakage, pollutes coal dust, while making bearing 10 owe lubrication.
Certainly, the setting of sealing ring is not influenceed by the first annular groove 5 setting graphite, depending on the actual conditions of feeder.
As shown in figure 4, as the further expansion of above scheme, the first recess 6 can be set towards the side of bearing hole 4
There is the second recess 7, the second recess 7 is used to store lubricant grease.Second recess 7 stores extra lubricant grease, both meets bearing
10 lubrication needs, can also absorb the heat that the operating of bearing 10 is produced, and accommodate the chip that the operating of bearing 10 is produced, make bearing 10
In normal working condition, thus extend the maintenance period of bearing 10, reduce maintenance work.
As shown in figure 5, as the further expansion of above scheme, the outer surface of body 1 can be provided with the second recess 7 of connection
Oil filler point 8, convenient filling lubricant grease simplifies the filling operation of lubricant grease, to be torn open to the addition lubricant grease of bearing 10
Unload bearing block.Oil filler point 8 can set blocking to be closed.
As shown in fig. 6, as the further expansion of above scheme, oil filler point 8 is connected with oil storage box 11, oil storage box 11 includes
The inner casing 12 and shell 13 of tubular, shell 13 are set in the outside of inner casing 12, and inner casing 12 and shell 13 are connected through a screw thread, inner casing
12 or shell 13 can be provided with the oil pipe being connected with oil filler point 8, rotational shell 13 or inner casing 12 can inject into oil filler point 8
Grease, or lubricant grease is extracted, complete the replacing to the lubricant grease of failure.
Above example is only not limited to illustrate the technical scheme of the invention, all without departing from this
Inventive spirit and any modification of scope or equivalent, it all should cover the scope in the invention technical scheme
It is interior.
