Description

The double screen banks of a kind of packaged type closes dressing machine
Technical field
The present invention relates to a kind of grain machinery equipment, be specifically related to the double screen banks of a kind of packaged type and close clear grain Machine.
Background technology
After reform and opening-up, China's premodern agriculture science and technology is developed rapidly, and grain yield is significantly Increase, also present the diversified trend of grain variety simultaneously.Along with people's living standard improves constantly, Grain processing quality is increasingly paid close attention to by masses.Owing to harvest machinery, harvesting method are different, Different region grain qualities is the most different, has many alloys to occur in grain after harvesting, for rear Continuous grain purchases, store, process and cause many difficulties.So, current grain processing process In the biggest to the demand of dressing machine.Dressing machine is again grain cleaner, is the one of grain sieving machine Kind, it is dependent on equipment blower fan and built-in vibration screening and grain and other industrial crops is carried out classifying screen Divide the equipment of removal of impurities.Reciprocal reciprocating sieve dressing machine in early days, applies in cereal cleaning operation the widest General a kind of cleaning machinery, is mainly used for clearing up the large, medium and small impurity in cereal, and carries suction Wind system, therefore have the effect of clear removing light impurities concurrently.Enter the nineties in 20th century, improved from Balance vibration is sieved, and its Main Function is the large, medium and small impurity in cleaning raw grain, if inhaled in configuration Wind separator, moreover it is possible to carry out selection by winnowing, with clear removing light impurities and dust.Itself uses vibrating motor to pass Dynamic, simple in construction, superior performance, not only dust removal rate is high, and yield is big, and compass screen surface is not easily blocked, and And the amplitude of compass screen surface, direction etc. all can facilitate regulation the most as required.Although it is improved Self-balancing vibratory sieve dressing machine superior performance, but the production technology of equipment is more complicated, it is impossible to meet Pang The cleaning demand in big raw grain market, and due to the mounting means of this equipment, method of operating etc. all without Method adapts to various different clear grain work on the spot environment, and limitation is bigger.
For above-mentioned situation, the double-sieve type dressing machine used the most on the market has carried out substantial amounts of improvement, The structure such as using Double-layer screen designs, and two layer screen body acupuncture carries out distribution to the foreign material of different volumes Remove, while improving impurity-eliminating effect, reduce floor space during equipment work;Set in the bottom of dressing machine Put train transfer, it is simple to dressing machine is moved in different places.
But find in practical work process, although this double-sieve type dressing machine solves the most clear grain The problem that machine exists, but or exist many not enough: such as it is difficult to essence due to conveyer feeding flow Quasi-control, the 1/3 stacked material sometimes going up cover surface occupies, and causes upper sieve sieving area Reduce and then occur that enrichment phenomenon occurs in screening, causing material skewness impact screening on upper sieve Effect, and then affect lower floor's screening effect;Sieve ship is gun iron link with screen frame (unit), and sieve ship inclination angle is through setting Cannot be adjusted according to practical condition after Ding;The discharge of impurity be take in natural environment to Under the mode dumped, easily swept along by natural wind, ascension is filled the air in atmosphere, causes staff's work Make bad environments but also environmental pollution can be caused.
Summary of the invention
For solving above-mentioned technical problem, object of the present invention is to provide the double screen banks of a kind of packaged type Close dressing machine, with solve existing double-sieve type dressing machine easily occur sieve enrichment phenomenon, sieve ship inclination angle The defects such as the impurity effect surrounding environment cannot adjust according to actually used situation, sifted out.
