Weigh cloth, vibrating motor on the screen box.
Advantageous effect：
1, traditional guipure sieve yield is big, but can only clear up big miscellaneous, and the utility model uses new screening process technology mode,
The amount of exercise that screening object is increased by vibration sieves mesh density by densification network band, and making originally can only the big miscellaneous guipure of screen
Sieve, it is miscellaneous in cleaning up also while together and to clean up part by delivery board small miscellaneous.
2, the utility model is by increasing vibration so that the treatment process of grain changes ----originally fall on compass screen surface
Static state straight trip passes through compass screen surface by static weight, falls into sieve pore in the moving ahead of the jump that becomes to jolt and passes through compass screen surface, promotes processing energy
Power several times, and material penetrance is increased, it has overturned traditional mistake porosity for being sized substance and has reduced because mesh size reduces
Idea, there is a kind of removal of impurities machinery of completely new grain.This makes the utility model while having large-mesh screen amount big
Advantage and screen in the good advantage of small miscellaneous effect, a kind of new grain machinery is createed in the same industry, in big yield premise
Large, medium and small miscellaneous efficient receiving sieve can be cleared up simultaneously down.
If 3, reducing operation miscellaneous during sieve pore is removed using traditional receiving sieve, in miscellaneous be easy to be embedded in mesh
In can not remove so that effective sifting area reduce, cause screen effect undesirable.The utility model is sieved by vibration and guipure
Linear motion sieved, realize grain great-jump-forward move ahead sieving technology, screen effect have is obviously improved.
4. traditional guipure sieve yield is big, but can only handle big miscellaneous.And traditional plane rotation receiving sieve is no matter as at
Reason it is big miscellaneous or in it is miscellaneous, effect is all undesirable, and the utility model makes it by changing the structure and sieving technology that traditional guipure sieves
Ensure large-tonnage advantage, under the premise of hardly increasing equipment cost, land area and height, increases place
Medium and small miscellaneous function is managed, small miscellaneous sieve sifting surface is increased by delivery board, while for conventional planar roto-siofter in first clear mistake
Undesirable situation is handled in journey, increases sieve cover for small impurities, and effectively increases screen number and screening length, plays vibrating screen
Advantage forms a kind of new sieving technology and new sieve-type.Compared with completing the traditional equipment of usual screening quality and weight, this practicality
Novel construction cost lowers more than half, has significant economic effect and technological progress.
4, multigroup transmission belt in the utility model screen box is housed, share vibrosieve, significantly improve impurity-eliminating effect, is improved
Equipment disposal ability.Due to reducing the usable floor area of building, the utility model is only built into originally less than half of
It can originally build up, form new large-scale grain impurity-removing machinery, fill up industry blank.
5, the parallel chain sprocket structure of the utility model, 2 pairs or 2 pairs of above-described sprocket wheels connect to be formed by chain respectively
Chain drive, parallel drive metallic screen piece, smooth working, strong shock resistance can be in even running under relatively high power.
6, traditional guipure sieve is by the grain of upper layer compass screen surface, directly falls and by lower layer's compass screen surface, only big miscellaneous forward,
Grain diffusion is poor, and the very short distance of process, mask work does not just continue to, so traditional guipure sieve length all compares
It is short, larger impurity can only be removed, so only just clear.And since traditional guipure sieves no diffusion function, addition is big
When be very easy to block.The compass screen surface of the utility model drives the function that grain is moved and jumped along its length, makes to fall above
The cutting including grain spread rapidly, and along compass screen surface movement forward, increasing the processing energy for shakeouing diffusion
Power.Meanwhile compass screen surface remote position is transported to by delivery board across the grain of compass screen surface, effectively increase screening process process
Length, be effectively increased processing yield.
7, the metal sieve of the utility model includes 2 kinds, and wherein sieve pore is more than the big-and-middle miscellaneous sieve of the size of grain,
Big or middle miscellaneous, and higher treatment effeciency can effectively be cleared out.The screen box has the support roller or bracket of one group of chain,
The waist that collapses is prevented, ensures the rolling flow direction of grain.
8, the delivery board of the utility model may be used conveying sieve plate, and compass screen surface gathers sieve pore, according to the particle of screening grain
Corresponding screen size is arranged in size, can sift out in time it is small miscellaneous less than grain, it is small it is miscellaneous into sieve plate lower part install sieve fall
Object accommodating case, the accommodating case connect impurity removal mechanism, and in the case where not increasing height and the place area of plane, this practicality is new
Type increases primary small miscellaneous cleaning machine between big miscellaneous screening twice, and after the bonding material for clearing out small miscellany, reducing bonding makes
Big miscellaneous screen effect has greatly improved, and significantly improves impurity-eliminating effect.The sieve plate inclination angle is 6-10 degree, and special angle was both
It ensure that the movement of grain and can realize maximum screening length.
9, the metal sieve of the utility model may be used metal mesh, handling ease, low cost, seamless, but be easy to become
Shape is solved by rigid cage in the utility model.
10, the utility model uses reciprocating screen division technique, is located between the sprocket wheel of grain-entering mouth side or on sprocket shaft,
There is impurity to exclude mechanism or chute impurities removal mechanism for the lower section for being connected with the impurity-discharing screw either sprocket wheel, will back and forth transport
Move tail end it is big it is miscellaneous clear out, completely eliminate the impurities accumulation and blockage problem among the annular space of two layer screen face, no
It needs often to shut down again, it is no longer necessary to which the manual cleaning process after dismantling, realization are worked continuously.
11, for the utility model by vibration so that screen end grain layer is thinning, screen is cleaner, is not easy to run grain, improves grain
The impurity-eliminating effect of food.It will be embedded in the sieve pore of particular size in some impurity motion processes.The utility model setting cleaning
Mechanism is removed, and the utility model is installing cleaning mechanism with the tangent position of the conveyer belt, is typically mounted at transmission
One end of band so that the metal sieve of conveyer belt is obtained for cleaning update in the motion process of each circumference.
12, the utility model additionally provides stacked scheme, the conveyer belt described in one group be fixed in screen box and on
Lower arrangement, homonymy enter grain, by tripper into the compass screen surface of different height balancing distributing, form parallel processing structure, simultaneously
The conveyer belt of different height can share a set of vibrating mechanism, improve workshop utilization rate, improve treatment effect.It is national continuous several
The bid project of the large-scale sieving machine of year publication, the utility model fully achieves treating capacity, energy-efficient requirement, and takes up an area face
Product and height are much smaller than the combination of existing equipment, are the developing direction of sieving machine.
