Abstract
The utility model relates to a cylindrical preliminary cleaning sieve which is cleaning equipment provided with double sieve cylinders with equal diameters, the inclination angle is adjustable, the assembly is in a segmented way, and raw grain can be winnowed and purified. The utility model has the advantages of novel structure, convenient maintenance, low energy consumption, low noise, high impurity eliminating efficiency, high processing capacity and wide adaptive range; a winnowing device can further separate parts of residual blended impurities in the net grain and the impurities in fine impurities; the axis inclination angles of the two layers of rotary sieve cylinders are adjustable, the outer cylinder and the inner cylinder can freely rotate with different angles synchronously under the action of an adjusting ring, which can screen different materials, and the transmission bearing capacity of the chain is high. The utility model has technical progress, and is indeed a novel preliminary cleaning apparatus with multiple functions.
Description
This experiment is novel to relate to a kind of cylinder receiving sieve, is cleaning, purifies the special equipment of raw grain.
Mostly existing cylinder receiving sieve is a kind of conical screen drum structure of fixed angle, must guarantee the axiality of conical screen drum and the depth of parallelism and the axiality that driving member is supported at the conical sieve tube two ends separately when making, use and keeping in repair.To the consumable accessory that uses in scene as the replacing driving member,, cause the service life of shortening equipment because the difference of technical conditions is difficult to assurance repair installation accuracy.
The purpose of this utility model provides the adjustable knotter screen tube of a kind of bilayer selection by winnowing combination receiving sieve.It can effectively reduce makes and installation accuracy, effectively improves service life, effectively improves cleaning, purifies the effect of raw grain, and can give to make and safeguard provides certain convenience and supremacy clause.
The purpose of this utility model is achieved in that double-deck cylindrical screen drum is the segmentation combining structure.Satisfying internal layer screen drum adjusting angle mechanism adopts power to shaft coupling and rubber riding wheel; The angle modulation scope that makes the internal layer screen drum is between the 0-10 degree.Satisfy the free inclination angle of outer screen drum and with internal layer screen drum synchronous rotating mechanism, adopt adjustable ring: outer screen drum nationality helps adjustable ring to rotate synchronously with the internal layer screen drum, simultaneously nationality helps adjustable ring driven with internal layer screen drum angle adjustment, the angle modulation scope of outer screen drum (be in the free inclination angle of outer screen drum adds screen drum be adjusted back rake angle be outer screen drum inclination angle) between the 4-14 degree.This machine transmission mechanism is made up of universal coupling, double-deck screen drum, rubber riding wheel, frame, adjustable ring, pneumatic separator.Adopting planet cycloid pin reductor is power: by chain drive, make the screen drum uniform rotation.Because this machine internal layer screen drum has adopted universal coupling, rubber riding wheel angle modulation structure and outer screen drum adjustable ring structure, thus realized screen drum and sieve sheet segmentation combination assembling.Surface configuration of bringing for manufacturing and site error all do not influence its screen drum and freely rotate normally, thereby manufacturing and installation accuracy have been reduced, reduced cost, significantly reduced noise, provide for manufacturing and working service and necessarily make things convenient for condition and supremacy clause.Thereby owing to adopted screen selection by winnowing unification structure and double-deck cylindrical screen barrel structure to dwindle machine volume, and improved raw grain cleaning purification level.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the complete machine structure figure according to the just clear rotary strainer of double-deck adjustable knotter screen tube selection by winnowing combination that the utility model proposes.
Be to describe in detail according to specific structural details and the working condition that the utility model proposes below in conjunction with Fig. 1.
This machine structure is by putting into pin gear speed reducer (4) through transmission mechanism (2) and the outer screen drum of universal coupling (1) transmission internal layer screen drum (3) (5) adjustable ring (8) rotation.The height and position distance of adjustment and change rubber riding wheel (10) can change the inclination angle of adjusting the internal layer screen drum.Adjustable ring (8) is positioned between internal layer screen drum (3) front end and outer screen drum (5) front end, and it is moving to form the cross axle transmission, the universal adjustment effect.Because outer screen drum (5) other end is the rear end is not have the free state of support, rearward end is sagging naturally under itself deadweight effect, point is attached to point on the inner layer screen tube rear end garden Zhou Tongyi all the time naturally on the screen drum circumference of its rear end, and under the gearing of adjustable ring, rotates synchronously.Thereby realized the purpose of outer screen drum (5) inclination angle greater than internal layer screen drum (3) inclination angle, the material that has promptly increased outer screen drum (5) is along compass screen surface downglide motion speed, therefore satisfied the cleaning amount of outer screen drum (5) simultaneously, greater than the purpose of the cleaning amount of internal layer screen drum (3).Raw grain enters the front end of internal layer screen drum (3) from feeding mechanism (9), the screen drum rotation, big impurity slips out the rear end along the internal layer compass screen surface and enters big assorted outlet (15), raw grain then passes the internal layer compass screen surface large aperture of gathering and falls into outer compass screen surface (5) around here, in the screen drum rotation, clean grain slip out along outer compass screen surface rear end enter clean grain outlet (13) but this moment the clean grain behind the outer sieve cover cleaning also contain big-and-middle impurity about 2% and about 40% light small impurities (mainly contains broken grain grain, sand grains, soil face and chaff skin) carry out the removal of impurities of secondary wind-force through pneumatic separator (14), thus improved the purity of clean grain.Light little thin impurity then passes the outer compass screen surface aperture of gathering and falls into the tiny assorted outlet of particle (12), the a large amount of light small impurities that is gone out is clearly discharged the gently assorted outlet (11) of chaff skin under wind action, the dust that is produced in this machine running cleaning raw grain process is through dust flue (6) sucking-off.Complete machine structure comprises frame (7).
The utility model is applicable to the clear general labourer's prefaces of industry raw grain slubbing such as grain depot storage, grain and oil processing, feed processing, system wine, flour processing, and the big assorted rate 98.5% of cleaning is cleared up little assorted rate and is not less than 70%, treating capacity 50-170 ton/hour.
The technical progress of the utility model is reasonable, satisfies the requirement of raw grain cleaning technology more widely, is the novel just clear equipment of multi-functional machine.
Claims (5)
1, a kind of cylinder receiving sieve comprises that screen drum, frame, dust flue, universal coupling, chain spoke circle, adjustable ring, colloid support roller, selection by winnowing blow material pipe, it is characterized in that screen drum one end has universal coupling, and adjustable ring is housed.
2, according to the just clear rotary strainer of the described combination of claim 1, it is characterized in that screen drum is the segmentation assembly.
3, according to the just clear rotary strainer of the described combination of claim 1, it is characterized in that support roller and universal coupling.
