Description
Technical field
The present invention relates to a kind of grain machinery equipment, and in particular to a kind of double screen banks of packaged type close dressing machine.
Background technology
After reform and opening-up, China's premodern agriculture science and technology is developed rapidly, and grain yield increases considerably, while
Show the diversified trend of grain variety.As people's living standard improves constantly, grain processing quality is increasingly by big
Many concerns.It is just different in different region grain qualities because harvest machinery, harvesting method are different, there are many dopants to go out
Now in grain after harvesting, many difficulties are caused for follow-up grain purchases, storage, processing.So current grain adds
It is very big to the demand of dressing machine during work.Dressing machine is called grain cleaner, is one kind of grain sieving machine, it be according to
The equipment for carrying out classification screening removal of impurities to grain and other industrial crops by equipment blower fan and built-in vibration screening.Early stage it is reciprocal
Reciprocating sieve dressing machine, widest a kind of cleaning machinery in cereal cleaning operation is applied to, is mainly used for clearing up in cereal
Large, medium and small impurity, and carry air draft system, therefore have the effect of clear removing light impurities concurrently.Into in the 1990s, by improving
Self-balancing vibratory sieve, its main function be clear up raw grain in large, medium and small impurity, if configuration air draught separator, also
Selection by winnowing can be carried out, with clear removing light impurities and dust.Itself is driven using vibrating motor, simple in construction, superior performance, is not only cleaned
Efficiency high, yield is big, and compass screen surface is not easily blocked, and the amplitude of compass screen surface, direction etc. can facilitate regulation as needed in production.
Although improved self-balancing vibratory sieve dressing machine superior performance, the production technology of equipment is more complicated, can not meet Pang
The cleaning demand in big raw grain market, and because the mounting means of the equipment, operating method etc. can not all adapt to various differences
Clear grain work on the spot environment, limitation is larger.
For the above situation, the double-sieve type dressing machine used on the market at present has carried out substantial amounts of improvement, such as using double
The structure design of layer screen cloth, two layer screen body acupuncture carry out distribution removal to the debris of different volumes, subtract while improving impurity-eliminating effect
Floor space when skinny device works；Train transfer is set in the bottom of dressing machine, is easy to dressing machine in different fields
Ground moves.
But found in practical work process, although this double-sieve type dressing machine solves asks existing for conventional dressing machine
Topic, but many deficiencies still be present：Such as because conveyer feeding flow is not easy to be precisely controlled, the 1/ of cover surface is gone up sometimes
3, which are stacked material, occupies, and causes upper sieve sieving area to reduce and then screening occur and enrichment phenomenon occurs, causes material in upper sieve
Upper skewness influences screening effect, and then influences lower floor's screening effect；It is gun iron link that ship, which is sieved, with screen frame (unit), sieve ship inclination angle warp
It can not be adjusted after crossing setting according to practical condition；The discharge of impurity is that the side dumped downwards is taken in natural environment
Formula, easily swept along by natural wind, ascension diffuses in atmosphere, causes staff's working environment severe but also can cause environment
Pollution.
The content of the invention
