Description
Technical field
It the utility model is related to rotary screen apparatus field, more particularly to a kind of roller sieve apparatus with helical blade.
Background technology
During regeneration concrete recycling, roller sieve apparatus is relatively common screening plant, and it is used for will be broken
Aggregate in broken concrete and fine particle after broken are sieved.
Such as notification number be CN203737551U Chinese patent disclose a kind of roller sieve apparatus, it include charging aperture,
Discharge gate, roller, rotating shaft, driving-transmission mechanism, the support of bearing, sieve aperture, rolling device and helical blade.
The rotating shaft of this roller sieve apparatus and helical blade rotate at work and roller is fixed, when needing to coagulation
When these bigger, harder materials of native fragment are sieved, rely solely on helical blade and be difficult to promote material to discharging opening
It is mobile, the consequence that material can be caused easily to be stuck in screen drum.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of rotary screen with helical blade
Equipment so that it more preferable can must promote material to be moved to discharge bucket, and material is not easy to be stuck in rotary screen.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of roller sieve apparatus with helical blade, including frame, the screen drum and drive device with sieve aperture, the machine
Frame is fixed with the feed hopper for material to be sent into screen drum and the discharge bucket of access screen drum discharging, and the frame is fixed with casing,
The screen drum is crossed in casing and is rotatably connected with casing, and the screen drum inner surface is welded with helical blade, the drive device
Screen drum is driven to rotate by V belt translation.
Whole equipment drives screen drum to rotate by drive device, enters the broken concrete of screen drum by helical-blade by feed hopper
Piece is promoted to move forward and simultaneously overturn in screen drum, broken concrete overturn and movement forward in, fine particle is from sieve aperture
Spill, and the larger aggregate of particle then continues to overturn and move forward until being discharged to discharge bucket in broken concrete.Due to
Helical blade rotates with screen drum together in screening process, rather than screen drum is fixed, is stirred by the helical blade rotated
Actionless broken concrete, so helical blade will not be blocked by broken concrete in rotation process, decrease coagulation
Shock of the native fragment to helical blade.
The utility model is further set, and the drive device includes motor, decelerator, output shaft and belt pulley, institute
The rotating shaft connection reducer of motor is stated, the decelerator, by exporting axis connection, has timing belt with belt pulley on the belt pulley.
By the setting using motor and decelerator as the drive device of combination, the stability of rotation of output shaft, is rotated during work
Moment of torsion increase, belt pulley can drive screen drum to rotate better by V belt translation.
The utility model is further set, and the screen drum outer surface is provided with the projection around screen drum circle distribution, the projection
It is meshed with timing belt.
By the setting of projection and the timing belt being engaged with, belt pulley and screen drum realize toothed belt transmission, and then make drive
Dynamic system can drive screen drum to rotate, and synchronous belt is non-slip during work, and screen drum rotates more steady.
The utility model is further set, and the tank ends face is provided with circular open, passes through spiral shell on the circular open
Bolt is fixedly connected with three uniform support rollers centered on circular open, and the screen drum is rotatable by the support roller on circular open
Ground is placed in casing.
By the setting of support roller, screen drum is rotatably disposed in casing, because trundle screen divides material institute in screen drum during work
Caused dust falls into casing and is not easy to form diffusion.
The utility model is further set, and the lower end of the casing is provided with the first discharging opening sifted out for fine particle.
By the setting of the first discharging opening, fine particle during work in material is sifted out by sieve aperture and arranged by the first discharging opening
Go out, without being deposited in casing.
By the setting of the first discharging opening, fine particle during work in material is discharged by sieve aperture by the first discharging opening,
Without being deposited in casing.
The utility model is further set, and the projection is distributed in the outer surface that screen drum stretches out the part of casing.
By the way that projection is arranged on into the part for stretching out casing in screen drum outer surface, the timing belt engaged with projection also is located at casing
Outside, it is easy to be adjusted timing belt replacing.
In summary, the utility model drives screen drum to rotate by drive device by timing belt, enters screen drum from feed hopper
Broken concrete by helical blade promote move forward and overturn in screen drum, broken concrete is overturning and moved forward
Cheng Zhong, fine particle therein spills from sieve aperture and has the first discharging opening to discharge casing, and particle is larger in broken concrete
Aggregate then continues to overturn and move forward to be discharged to discharge bucket.Because helical blade turns with screen drum together in screening process
Move, rather than screen drum is fixed, actionless broken concrete is stirred by the helical blade rotated, so rotation process
Middle helical blade will not be blocked by broken concrete, decrease shock of the broken concrete to helical blade, and whole equipment is fitted
For sieving broken concrete these bigger, harder materials.
