Description
Technical field
The utility model relates to grain conveying equipment field, especially a kind of water proof and dust proof conveying roller.
Background technique
Usual grain is sent into warehouse by inclined conveyer belt to be stored, and has rotation setting below conveyer belt
The conveying roller of support belt.
In grain output equipment, conveyer belt itself does not need to bear biggish load, and still, there are this in transport environment
A large amount of dust, also, conveying equipment would generally be exposed in open-air atmosphere in storage, transportational process, and conveying roller has larger
It is likely to be exposed rainwater, dew etc..Dust and water can damage the bearing in conveying roller, and conveyer belt transfer efficiency is caused to drop
The problems such as low.
Summary of the invention
The purpose of the utility model is to provide a kind of conveying rollers of water proof and dust proof.
In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of water proof and dust proof conveying roller comprising turns
Axis, cylindric roller and the bearing being arranged between the shaft and the roller, the both ends of the roller are provided with closure
Component, the blocking component include the support portion being fixedly connected with the roller inner wall, the sealing being arranged in the support portion
Circle, the shaft passes through the bearing and the sealing ring is arranged, and the support portion includes being fixedly connected with the roller inner wall
Fixed part, the mounting portion for installing the bearing, the connection fixed part and the mounting portion outer end interconnecting piece, with
And the sealing of pore-forming is shunk from the inner end of the mounting portion, the bearing is passed through from the sealing.
Preferably, the sealing ring includes that the inner seal ring on the inside of the bearing is arranged in and is arranged on the outside of the bearing
Exterior seal ring.
It is further preferred that the inner seal ring is close to the sealing setting.
It is further preferred that the exterior seal ring includes the first washer portion being arranged on the mounting portion and is arranged in institute
The second packing ring portion on bearing is stated, there are two sealings being bonded to each other between first washer portion and the second packing ring portion
Face.
It is further preferred that the section of the sealing surface is wavy or sawtooth state.
It is further preferred that being provided with seal grease between two sealing surfaces.
It is further preferred that being arranged with the card for stopping the second packing ring portion to be displaced outwardly in shaft.
Preferably, the support portion is mutually welded and fixed with the cylinder inner wall.
Since above-mentioned technical proposal is used, the utility model has the advantage that compared with prior art
Since blocking component is arranged at roller both ends in the utility model, can stop to enter roller from outside water and dust
Bearing, furthermore blocking component can also organize the dust in roller to enter bearing, can play preferable water proof and dust proof effect.

Bearing 3 between axis 1 and roller 2, the both ends of roller 2 are provided with blocking component, and blocking component includes solid with the welding of 2 inner wall of roller
Surely the support portion 4 connected, the sealing ring being arranged in support portion 4, shaft 1 passes through bearing 3 and sealing ring is arranged, and support portion 4 wraps
Include the fixed part 41 being fixedly connected with 2 inner wall of roller, the mounting portion 42 for installing bearing 3, connecting portion 41 and mounting portion
The sealing 44 of pore-forming is shunk in the interconnecting piece 43 of 42 outer ends and the inner end in self installation portion 42, and bearing is worn in 3 self-sealing portion 44
It crosses.
Sealing ring includes the inner seal ring 51 that 3 inside of bearing is arranged in and the exterior seal ring 52 that 3 outside of bearing is arranged in.It is interior
Sealing ring 51 is close to sealing 44 and is arranged.
Exterior seal ring 52 includes the first washer portion being arranged on mounting portion 42 and the second packing ring being arranged on bearing 3
Portion has two sealing surfaces being bonded to each other between the first washer portion and second packing ring portion.Specifically, the section of sealing surface is wave
Wave-like or sawtooth state are provided with seal grease between two sealing surfaces.
The card 6 of the annular for stopping second packing ring portion 44 to be displaced outwardly is arranged in shaft 1.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
