Description
Technical field
A kind of Cereals Processing Machines equipment is the utility model is related to, more particularly to a kind of screen drum of cylindrical pre-cleaning screen.
Background technology
Cylindrical pre-cleaning screen is for removing the big miscellaneous Cereals Processing Machines equipment in raw grain, traditional cylindrical pre-cleaning screen sieve
Cylinder is that the parts such as screen frame, sieve plate, helical blade are welded into an entirety, the position of sieve plate and helical blade be it is fixed, no
Can assembly and disassembly.When cylindrical pre-cleaning screen works, material flows into one end of screen drum along tremie pipe, former under the turning effort of screen drum
The sieve aperture that grain can be penetrated on sieve plate is fallen into hopper, more than the paper of sieve diameter, polybag, stalk, the rope made of hemp, brick on sieve plate
The big miscellaneous other end that screen drum can be flowed to along the guiding of helical blade such as block, will be big miscellaneous from raw grain so as to realize into big miscellaneous bucket
The purpose of middle separation.But material along tremie pipe flow into screen drum when, material can form one very big impulsive force to screen drum, because
The same position of material long-time repeated stock screen drum sieve plate, sieve plate can be caused damaged, screen drum can be caused to be rushed in material when serious
Place's fracture is hit, damages machine.Just as this damage parts of sieve plate and whole screen drum must be changed, cause human and material resources and
The waste significantly of financial resources.Furthermore helical blade is welded on position fixed in screen drum, pitch can not be adjusted, and it is clear to reduce equipment
The technological effect of reason.
The content of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, there is provided a kind of sieve of cylindrical pre-cleaning screen
Cylinder, is dismountable assembly type screen drum, and it can not only effectively remove big miscellaneous in raw grain, and sieve plate, sieve plate press strip, spiral
Blade is all interconnected with bolt, and detachable and replacing, the pitch of helical blade can adjust.
The purpose of the utility model, is achieved by the following technical measures：A kind of screen drum of cylindrical pre-cleaning screen, including circle
Shaft screen frame, punching sieve plate, sieve plate press strip and helical blade；The cylinder screen frame is by three disc flanges being equidistantly spaced from and company
Some main linings being connected between disc flange are welded, and main lining is vertical with disc flange, and main lining is set at equal intervals along disc flange
Put, whole cylinder screen frame is separated out to the section of the sizes such as some, one piece of punching sieve plate, the disc flange are arranged in each section
Inner ring be welded with annulus for fixing stamped sieve plate, be connected with sieve plate press strip, cylinder screen frame front end on the inside of the main lining
Disc flange on be welded with screen drum reinforcement and strengthen reel flanges；The helical blade is looped around the inwall of cylinder screen frame, spiral shell
It is connected between vane piece and punching sieve plate.
In the above-mentioned technical solutions, the disc flange of composition cylinder screen frame, main lining, annulus, screen drum reinforcement, stopping-off piece method
The positioning using tenon and mortise in the form of at blue interconnection, it is ensured that cylinder screen frame size it is accurate.
In the above-mentioned technical solutions, it is bolted between the annulus on the punching sieve plate and cylinder screen frame, can be with
When dismantle and change, can arbitrarily be exchanged between sieve plate and sieve plate, individual sieve plate up and down, right position relation can also adjust at any time
Change.
In the above-mentioned technical solutions, it is bolted between the sieve plate press strip and main lining, can dismantles and change at any time,
Can arbitrarily it be exchanged between sieve plate press strip and sieve plate press strip, the upper and lower of single sieve plate press strip, right position relation can also be adjusted at any time
Change.
In the above-mentioned technical solutions, the helical blade of the drum sieve inframe is joined end to end by several pieces forms, helical blade
It is bolted between punching sieve plate, can dismantles and change at any time, or the pitch of change helical blade.When needing to increase
Whole helical blades is pulled down during pitch first, removes several helical blades therein, widens the pitch of remaining helical blade
Afterwards, then again through bolt by remaining helical blade join end to end fixed on punching sieve plate.When needing to reduce pitch, behaviour
Make opposite.
The screen drum of the utility model cylindrical pre-cleaning screen uses dismountable modular construction, sieve plate, sieve plate press strip, helical-blade
All interconnected between piece and cylinder screen frame with bolt, detachable and replacing, the pitch of helical blade can adjust.This practicality is new
Type design is unique, and structure is novel, and it can not only effectively remove big miscellaneous in raw grain, and only need to more renew sieve after damages of screen deck
Plate, without changing whole screen drum, save human and material resources and financial resources.To prevent the same of material long-time repeated stock sieve plate
Damages of screen deck is caused in position, can often reverse end for end to use by sieve plate, can also exchange leading portion sieve plate and back segment sieve plate using after 1 year
Use, make sieve plate uniform wear so as to reach to improve the purpose of screen drum service life.Meanwhile by adjusting the spiral shell of helical blade
Away from the needs that can also meet different treating capacities and cleaning technology.
