The design is improved to the particle discharge zone 3 of tracing to the source of traditional vibratory sieve, and the particle discharge zone 3 that will trace to the source is transformed into
One ramp type.Rectangle iron plate is welded with the reclaiming plate of ramp type.Iron plate is staggered welding according to left and right, is formed
One discharging track, while reclaiming plate is also designed to sieve-board type.So tracing to the source particle will be one along this discharging track
Individual arrangement enters conveyer belt, while can carry out regrading to not sieved complete wheat on the vibrating.Trace to the source particle
The overlooking the structure diagram of discharge zone 3 is as shown in Figure 5, front view structure illustrates as shown in fig. 6, the multiple experiment repeatedly of warp is drawn：Its
The rectangle iron bar and horizontal angle of middle welding are all a=6 degree, angle β=23 degree of whole reclaiming plate and horizontal plane, are gone out
Flitch is an isosceles trapezoid, wherein L=0.28m, M=0.248m, K=0.012m, A=0.22, C3=6mm, L3=8.5mm,
B=0.18m, C=0.12m, D=0.05m, E=0.04m, X=0.085m, W=0.13m, Y=0.065m, Z=0.07m.
(19) design of vibration sieve plate
Vibration sieve plate 2 is the main working parts of vibratory sieve, and the vibration sieve plate 2 mainly used in production at present has three
Kind, it is respectively：Grizzly, stamped sieve, wire gauze sieve.In the engineering practice of wheat processing, grizzly and wire gauze sieve are not suitable for wheat
Yielding in vibration processes, uneven surface is sieved in screening, establishment, it is difficult to ensures whole compass screen surface on the same face.Therefore local oscillator
Punching sieve plate is selected in dynamic screening.The design is that the particle that will trace to the source is as oversize using wheat as screenings.When the size of material is small
In the 0.75 of screen size, belong to easily sieve material.And then belong to difficult screened material when being more than the 0.75 of screen size.The sieve plate of design
Screen-aperture should meet wheat size be less than screen size 0.75, such wheat can be just easier as under sieve
Thing sifts.And the size for particle of tracing to the source should be more than the size of sieve aperture.Therefore, from the circular hole punching that pore size is 6mm
Sieve plate, pitch-row 2.5mm.
The aligning method of sieve aperture has square arrangement, be staggered two kinds of forms.Square arrangement is longitudinal and transverse two directions
The arrangement of sieve apertures method all alignd.Pitch-row between each hole simultaneously differs, so the intensity on compass screen surface everywhere is also not consistent.Separately
Outside, simultaneously non-mesh may cause material to walk airway between two row sieve apertures of square arrangement, reduce the sieving machine meeting of material, institute
It is relatively low with screening efficiency.Be staggered the arrangement mode for referring to that only a direction is mutually aligned.Pitch-row between each hole is equal,
Therefore the intensity everywhere on compass screen surface is consistent, and material can be walked without airway so that sieving machine can increase, and be advantageous to screening efficiency and carry
It is high.Arrangement of sieve apertures method directly influences the usage factor of compass screen surface and material falls into the chance of sieve aperture.Sieve aperture is staggered
It is better than square arrangement in the effect of screening, so in production use staggered pattern more.According to national standard GB/T 10612-
2003, for the sieve plate of the design using being staggered, schematic diagram is as shown in Figure 7.Wherein sieve wide A2=248mm, sieve long B2=752mm,
Aperture C2=6mm, pitch of holes L2=8.5mm.
(20) the saturating sieve probability theory of vibratory sieve
Saturating sieve probability differs in size in the size of screen rate, and it is the complexity that explanation material sieves thoroughly to sieve probability thoroughly,
Though there is calculated value, simply qualitatively analyze.And screen rate is to quantify explanation material to sieve complexity thoroughly, screen rate more can be accurate
The saturating sieve situation of true reflection material, but both are unified in theory.
In actual design, compass screen surface has certain inclination angle, to meet the needs of various screenings and requirement.Sweden scholar
F.Mogensen proposes single spheric granules and tilts the saturating sieve probability theory thrown and tilted on compass screen surface.Fig. 8 is inclined-plane compass screen surface.From
Fig. 8 is it can be seen that the saturating sieve probability P of single spheric granules is：
In formula：A is that the length of side of round sieve is 6mm, and b is a diameter of 2.5mm of silk screen, and d is the diameter of spheric granules,It is
Screen angle is 5 degree, and δ is that the angle of the direction of motion and gravity direction is 15 degree during particle declines.For silk screen inside portion
Divide the saturating sieve coefficient with spheric granules collision rift.Ask method as follows：
This experiment is using wheat as screenings, and wheat size is long 6.5-7.64mm, the wide 2.9-3.67mm in both sides.From
Round-hole punched plate, sieve aperture length of side 6mm, pitch of holes 2.5mm, 5 degree of screen angle, 15 degree of pan feeding deflection.Regard wheat approximation as ball
Shape particle (diameter takes 3mm) brings formula estimation sieve Probability p thoroughly into2For 14%.
(3) conveyor belt design
To meet to design needs, the height of conveyer belt 11 should be less than the height for particle discharge zone 3 of tracing to the source, same to save space
When meet transmission demand, length and width should not be too big, and length is 1.51 meters, and width is 0.155 meter.Opposite type sensor 9, air-blowing
Mouth 8, the installation site of two-dimensional bar code scanner 7 are as shown in Figure 9.Air-blowing overlong time can cause to unidentified particle of tracing to the source below
Influence, the air-blowing time too short effect for not having sorting, therefore the air-blowing time that the design is set is 300ms.Particle is traced to the source from tracing back
The time interval that source particle discharge zone 3 is entered between conveyer belt 11 former and later two particles of tracing to the source is about t=500ms, to protect
Demonstrate,prove particle longitudinal separation of tracing to the source and be more than s=5cm, then the speed of conveyer belt 11 is at least v=s/t=0.05m/0.5s=0.1m/
s.Because the scanning area of two-dimensional bar code scanner 7 is fixed, therefore in the original position of conveyer belt 11, a postive stop baffle 4 to be installed,
Effect is to ensure scanning area of the particle just by two-dimensional bar code scanner 7 of tracing to the source.Particle of being traced to the source on the right side of conveyer belt 11 is read
Take unsuccessfully at disposable box 15, the curved baffle 10 of a transverse direction need to be installed, curved baffle 10 is rectangular rubber bar, and one end is fixed

Starting point is line of demarcation on the right side of the identification region of scanner 7, and conveyer belt 11, the left side in line of demarcation are close in the right side position in line of demarcation
Position is hanging, and flying height is more than particle height of tracing to the source.The benefit so designed is：Position utilizes conveyer belt 11 on the right side of line of demarcation
And before and after the frictional force for particle of tracing to the source and adjacent particle of tracing to the source between thrust, unidentified particle of tracing to the source is eventually entered into source particle
Read in failure disposable box 15, and the particle of tracing to the source identified is directly transferred to the tail end of conveyer belt 11 without by the curved baffle 10
Block；Transverse baffle 24 is the baffle plate of a middle opening, and the width of opening is not more than the identification region of two-dimensional bar code scanner 7
Width, the particle that can play a part of preventing tracing to the source, which is blown, to move back triggering opposite type sensor 9 again and causes secondary identification.
(4) circuit control module operation principle
When opposite type sensor 9 detects that particle passes through, opposite type sensor 9 produces trailing edge signal.Mould is controlled by center
Block, gives two-dimensional bar code scanner 7 one low level signals, and two-dimensional bar code scanner 7 is started working.When the end of scan, two dimension
Bar code scanner 7 is changed into high level from low level, is again at holding state.After the end of scan of two-dimensional bar code scanner 7, a side
Scanning result is transmitted to host computer 21 by face by serial communication, and result on the other hand is fed back into Central Control Module.Work as scanning
During failure, Central Control Module makes relay start working, and relay forms path, and air compressor 16 is started working, and produces
Gas load.The particle of tracing to the source of scanning failure is changed movement locus, by tracing to the source for the right side of conveyer belt 11 by gas load
Particle reads failure disposable box 15 and collected.When scanning successfully, relay still keeps off state, and air compressor 16 does not work,
The successful particle of tracing to the source of scanning directly reads successful collection box 12 by the source particle of the tail end of conveyer belt 11 and collected.Grain is automatically separated
The circuit control module schematic diagram of retrospective device is as shown in Figure 10.
