Description
Technical field
The utility model relates to a kind of belt conveyors, more specifically, it relates to which a kind of be used for belt conveyor roller
On protective device.
Background technique
Concrete mixing plant is more and more at present, and in concrete whipping process, the materials such as sandstone easily fall into Belt Conveying
Roller is worn at the roller both ends of machine, reduces belt life, increases production cost, when serious even can stuck roller, influence normal
Production；The objects such as sandstone wear roller in order to prevent, fix in the shaft of general conveyer by shield, but this shield and rolling
Between cylinder or there is very big gap, the objects such as sandstone still can fall into roller both ends and cause to wear to roller, and if anti-
Gap is too small between shield and roller, and shield inevitably rubs between roller, causes to wear to roller.
Utility model content
In view of the deficienciess of the prior art, being not easy to fall into rolling the purpose of this utility model is to provide objects such as a kind of sandstones
Cylinder both ends and the protective device that is used for belt conveyor roller on good to roller protection effect.
To achieve the above object, the utility model provides following technical solution: one kind is for belt conveyor roller
Protective device, including shaft and with shaft rotation connection roller, roller two sides in shaft be equipped with not higher than conveyer it is defeated
Send the shield in face, shield include with the axle sleeve of rotation axis rotation connection, the rotating disc being slidably connected with axle sleeve and with rotation
The cover of disk connection, cover are in hollow cylindrical, and rotating disc is placed in cover, and cover is coaxial with rotating disc, the outer wall of axle sleeve in
It is opened on length direction there are three sliding slot, three sliding slots are arranged in positive triangle shape, and rotating disc is equipped with three to be slidably connected with sliding slot
A fastener, sliding slot is interior to be equipped with the first elastic component, and first elastic component one end is connect with axle sleeve, and the first elastic component other end is supported with fastener
Touching.
Further, cover end is equipped with movable part and connects the second elastic component of movable part and cover, and movable part is in
Circular and movable part and cover are coaxial, and movable part is equipped with elastic cushion, and elastic cushion and roller contradict.
Further, rotating disc is placed on cover length direction at half.
By using above-mentioned technical proposal, when conveyer works, when the objects such as sandstone fall to roller both ends, cover is by sandstone
Equal objects block, and the objects such as sandstone slide from cover, and the objects such as sandstone is prevented to be caught between roller and shaft, protect the normal fortune of roller
Turn, simultaneously, it is ensured that roller is not easy to be worn；Cover and shaft are rotatablely connected, when roller and cover generate friction, roller and cover
For rolling friction, the frictional force of roller and cover is substantially reduced, so that roller is not easy to be worn；Rotating disc is placed in two in cover
At/mono-, so that the objects such as sandstone are not easy to fall into the junction of rotating disc and shaft, prevent the objects such as sandstone from influencing the rotation of cover,
And then ensure that roller is not easy to rub due to rotating disc is stuck with shaft with cover；Three sliding slots, the first elastic component and fastener
Setting reduce the frictional force of cover and roller so that cover is not easy stuck with roller, while making the cooperation of cover and shaft
It is more stable.
The setting of movable part and the second elastic component, elastic cushion and roller on movable part contradict, so that band when roller rotates
Dynamic cover rotation, and elastic cushion plays the role of sealing, sealed chamber will be formed between cover and roller, prevents the objects such as sandstone
Roller both side ends are fallen into, to influence the rotation of roller, the protection dynamics of roller is further enhanced；Second elastic component is then prevented
Only roller and cover, which are formed, is interference fitted, and roller is stuck, meanwhile, so that elastic cushion and roller contradict more closely sealing
Effect is more preferable, more efficiently to prevent falling into for the objects such as sandstone.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment
Fig. 2 is the structural schematic diagram of shield.
Fig. 3 is the schematic cross-sectional view of shield.
Specific embodiment
The utility model embodiment is described further referring to figs. 1 to Fig. 3.
A kind of objects such as sandstone be not easy to fall into roller both ends and to roller protection effect it is good for belt conveyor roller
Protective device.
The specific embodiment of the utility model: including shaft 1 and the roller 2 being rotatablely connected with shaft 1,2 two sides of roller
In shaft 1 be equipped with not higher than conveyer conveyor surface shield 3, shield 3 include with rotation axis rotation connection axle sleeve 4,
The rotating disc 5 being slidably connected with axle sleeve 4 and the cover 6 connecting with rotating disc 5, cover 6 are in hollow cylindrical, and rotating disc 5 is placed in
In cover 6, cover 6 and rotating disc 5 are coaxial, and for the outer wall of axle sleeve 4 in being opened on length direction there are three sliding slot 7, three sliding slots 7 are in just
Triangular shape arrangement, rotating disc 5 are equipped with three fasteners 8 being slidably connected with sliding slot 7, and the first elastic component 9 is equipped in sliding slot 7, the
One elastic component, 9 one end is connect with axle sleeve 4, and 9 other end of the first elastic component and fastener 8 contradict；Rotating disc 5 is placed in 6 length side of cover
At upward half.
6 end of cover is equipped with movable part 10 and connects the second elastic component 11 of movable part 10 and cover 6, and movable part 10 is in
Circular and movable part 10 and cover 6 are coaxial, and movable part 10 is equipped with elastic cushion 12, and elastic cushion 12 and roller 2 contradict.
Conveyer work when, when the objects such as sandstone fall to 2 both ends of roller, cover 6 blocks the objects such as sandstone, the objects such as sandstone from
It is slid on cover 6, the objects such as sandstone is prevented to be caught between roller 2 and shaft 1, protect the normal operation of roller 2, simultaneously, it is ensured that rolling
Cylinder 2 is not easy to be worn；Cover 6 and shaft 1 are rotatablely connected, and when roller 2 and cover 6 generate friction, roller 2 and cover 6 are to roll
Friction, substantially reduces the frictional force of roller 2 Yu cover 6, so that roller 2 is not easy to be worn；Rotating disc 5 is placed in two in cover 6
At/mono-, so that the objects such as sandstone are not easy to fall into the junction of rotating disc 5 Yu shaft 1, prevent the objects such as sandstone from influencing turning for cover 6
It is dynamic, and then ensure that roller 2 is not easy to rub due to rotating disc 5 and shaft 1 are stuck with cover 6；Three the 7, first elasticity of sliding slot
The setting of part 9 and fastener 8 so that cover 6 is not easy, the frictional force of reduction cover 6 and roller 2 stuck with roller 2, while making cover
Body 6 and the cooperation of shaft 1 are more stable.
The setting of movable part 10 and the second elastic component 11, elastic cushion 12 and roller 2 on movable part 10 contradict, so that roller
Cover 6 is driven to rotate when 2 rotation, and elastic cushion 12 plays the role of sealing, will form seal chamber between cover 6 and roller 2
Room prevents the objects such as sandstone from falling into 2 both side ends of roller, so that the rotation of roller 2 is influenced, it is further to the protection dynamics of roller 2
Enhancing；Second elastic component 11 then prevents roller 2 and cover 6 forms interference fit, and roller 2 is stuck, meanwhile, so that elastic cushion 12
It is contradicted more closely with roller 2, sealing effect is more preferable, more efficiently to prevent falling into for the objects such as sandstone.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, the skill of this field
Art personnel carry out common variations and alternatives within the scope of technical solutions of the utility model should be included in the guarantor of the utility model
It protects in range.
