Description
Technical field
The utility model belongs to sieving machine technical field, and in particular to a kind of vibratory sieve assembly of united reaper.
Background technology
Nowadays, the agricultural economy output value is growing, agricultural machinery modernization high speed development, the use of farm machinery with energetically
The agriculture business work that promoting makes field heavy has switched to mechanization by manpower, greatly reduces mass peasants in the arduous work in field
Workload.As agricultural machinery is to more efficient, more facilitation direction development, farm machinery has obtained the heat of the vast farmerses masses
Strong to welcome, market prospects are very considerable, further promoted the development of mechanization of agriculture.In the total output of grain that China is annual
In, the yield of paddy rice and wheat has exceeded the half of total output, and its cultivated area, throughout all parts of the country, is China most important two
Generalized grain crop, because the harvest of paddy rice and wheat relies primarily on united reaper, therefore determines united reaper in agricultural
The very important status of mechanical field so that its production scale also expands year by year.
The sieving machine of wherein harvester is the special equipment for being screened and being classified to bulk granular material in engineering, and its is main
Function be bulk granular material is classified, is dehydrated, desliming, de-mediated and by quality sorting.The result of screening operation is not only affected
The efficiency of next step operation, and also contribute to the commodity value that directly or indirectly produces.Motion of the bulk granular material on compass screen surface
State has the extremely complex mechanical characteristic similar to fluid, to improve design level, the synergy consumption reduction of sieving machine, urgently
Need to understand in depth motion state of the bulk granular material on compass screen surface and sieve rule thoroughly.Vibratory sieve is the groundwork of united reaper
Part, is also the most frequently used sieving machine in current engineering.Sieve performance is to need to consider in the design and application of vibratory sieve
Major issue, but existing Screening theory can not satisfactorily solve these problems, because existing Screening theory is for examination
The dependence tested is very big, and it so not only wastes time and energy with generally requiring to combine substantial amounts of experiment, often cannot also ideal
Result.
In recent years, as the research to sieving machine deepens continuously, in screen box structure, compass screen surface movement locus and compass screen surface material
In terms of carry out substantial amounts of research work so that it is developed rapidly and perfect.Its development trend has following several respects：
(1) develop to standardization, generalization, seriation.This is easy for designing, organizes Virtual production, ensure quality and
Reduce the approach of cost.The width of USL, USK screen(ing) machine of German KHD companies is using 200mm as one grade.Length is using 750mm as one grade
Constitute two serial 45 kind specification products.Its screen cloth, crossbeam, power transmission shaft, feedboard, reclaiming plate are realized standardization, led to
With change, vibrator also only has three kinds.The Carl Schenck AG of Germany is cold and hot simultaneously sinters jig and equal thick screen only general two kinds of vibrators,
It can be seen that three change the height of degree.
(2) develop to maximization, the maximization of sieving machine is conducive to improving treating capacity, expands the scale of production, and improves life
Efficiency is produced, convenient management improves the economic benefit of enterprise.In recent years, large-scale sieving machine development both domestic and external is swift and violent.It is so-called big
Its specification limit is not provided in type screening machine, design specification.General width is in more than 2.4m, and area is in 15m2With
On, it is believed that it is large-scale screening machine.The width of German Shen gram (SCHENCK) company manufacture is 4m, and length is 8.5m, area
For 34m2Coke screening machine, disposal ability reach 800m3/h.The single shaft of German sieve technology company (SIEBTECHNIK) manufacture
The effective width of vibratory sieve is 2.4m to the maximum, and length is 6m；And the effective width of dual-axis vibration sieve is 5.5m to the maximum, length is
11m.The maximum specification of the HLW type linear vibrating screens of day Benshen's steel development is width 3.6m, and long 7.5m, area is 24m2's.Japan
Kawasaki Heavy Industries have also been developed wide 4m, and long 9.5m, area is 38m2Linear vibrating screen.Mine building materials are held in the U.S. within 2003 to set
The width for the three shaft vibrations sieve put on display in standby exhibition is all in more than 2m.
(3) develop to ideal movements track vibrating screen, screening machine unit area disposal ability under certain screening efficiency,
Depend greatly on the movement locus of screen cloth.Achievement in research for decades is largely reflected in the motion of screen cloth
In the change of track.The movement locus of screen cloth develops into a variety of curves from straight line；Developed from linear to non-linear；From plane
Curve is to spatial complex curve, to adapt to handle the requirement by sieve material of various different qualities.
(4) vibration mechanism of vibratory sieve will break through traditional vibration shape, and take new vibration mode, fundamentally solve
Certainly vibratory sieve at present some insoluble subject matters.From the aspect of the Theory of Vibration used, traditional determination can be broken through
Property linear oscillator it is theoretical, and use the stationary linear random vibration theory more tallied with the actual situation and Nonlinear Random Vibration reason
By.
(5) motor synchronizing technology is applied, it is same to realize that synchronous self-synchronizing vibrating screen need not install gear using mechanics principle
Device is walked, structure can be simplified, noise is reduced, equipment fault is reduced, maintenance cost is saved.Motor synchronizing formula vibratory sieve will be obtained further
Development.
(6) develop to difficult screening materials carrying screen(ing) machine, moisture content 7%~14%, granularity exist in below 6mm fine moist material
Agglomerating, blocking screen cloth is easily bonded in screening process, difficulty is sieved very big.Domestic and foreign scholars are successively designed for difficult screened material
Polytype screening plant, mainly there is rotary probability screen, flip flop screen, equal thick screen extension set, piano wire screen etc..By decades not
Disconnected to explore, the material sieving technology of fine moist material has been made significant headway, but still needs to preferably solve the machinery of screening machine
Contradiction between intensity and technological effect.
(7) noise is further reduced because vibration screening machinery operating noise is big, is worked under hard conditions.How improved structure,
Using more reasonably kinetic parameter, still one important topic of research of noise is reduced.
(8) high reliability, the development of reliability, maintainability, safety and human factors vibratory sieve.
It is contemplated that continuous ripe and perfect with vibrosieve technology, the structure of vibratory sieve can more rationally can be entered
One-step optimization and standardization, making the production cost and maintenance cost of product further reduces, and screening efficiency and productivity ratio can enter one
Step is improved.
