"Seed Cleaner"

The innovation "relates to a seed cleaner with a separate Suction fan and with an adjustable crop infeed device as well as with acting alternately one after the other on the crop Air separators and reciprocally driven vibrating screens as well as with trieurs below or next to them.

In the following, the cleaning of seeds is to be understood in such a way that not only impurities, like weed seeds, ear scraps, clods of earth and sand, stones or dglo, are removed but it will go beyond that Also, a sorting of the freed of impurities, essentially pure of foreign additions, is carried out, in such a way that the seed from the grain released by the machine or the cleaner is almost uniform Size and of almost uniform grain weight. The cleaning is therefore also largely with a sorting connected"

Known seed cleaners are, as already mentioned, equipped with air separators, and they have vibrating sieves on. Together, the wind sifter and the shuttling

sieve a good duration run, when passing the good is alternately subjected to the influence of the air classifier and vibrating sieve. Seed cleaners generally exhibit Sohüttelsiebe inclined in the same direction, although it is already known to combine these vibrating sieves in groups and to drive the individual groups in opposite directions for the purpose of balancing the masses. The known seed cleaners have a disadvantage the relatively large space requirement, which in some known designs is increased by the fact that the suction fan in the cleaner is included. The performance of a seed cleaner, i.e. the amount of material that the cleaner per The unit of time that can be recorded and processed in seeds of a given purity is compared to the size of the in Occupied space is relatively small. The performance of the known seed cleaners cannot be achieved without considerable Increase construction and space requirements.

The task of the innovation is to design a seed cleaner of the type mentioned at the beginning so that it can be compared to known Versions with small structural dimensions, i.e. with a compact design, have a significantly higher performance.

To solve this problem, the said seed cleaner is newly designed so that the crop inlet device a container with a roof-shaped, height-adjustable and pivotable base held about its longitudinal center line has adjustable roof pitch, which is equipped with two arranged in separate Windiohtern Gutlaufkanteη, and

that on each of the two air classifiers at least two V-shaped superimposed vibrating screens and one on each of them Hauptsteigsiohter is connected, being similar Vibrating sieves are arranged in pairs on top of one another and the main ascenders are arranged next to one another, so that two are known per se parallel good treatment lines are created.

With the new seed cleaner, two streams of material are generated by the inlet device. It is possible, under all given conditions, to produce two fine, but closed veils of material from the material inlet device, which are necessary to carry out a careful and economical cleaning. This is done by adjusting the roof-shaped bottom of the inlet device accordingly. An air sifter is assigned to each runoff edge of the roof-shaped floor and a pre-screen to each of the two air sifters. In the new design, the two pre-sieves are arranged parallel to each other and one above the other in a common vibrating screen box, and the clean material they dispense enters another sieve box, which contains sorting sieves arranged in a V-shape to the first or pre-sieves, which in turn are arranged parallel to one another are. The transfer of the material from the pre-sieve to the sorting sieve takes place in such a way that the two material flows are not mixed, ie a specific sorting sieve is assigned to each pre-sieve. After passing through the sorting sieves, the material passes through so-called main ascending separators, which are arranged parallel to one another, each sorting sieve being assigned a main ascending sifter so that the flows of material leaving the sorting sieve

are fed to the separate ascending separators without mixing «This maintenance of separate streams of material in the parallel treatment sections guarantees high machine performance with little space requirement because U ₀ a« ensures a covered, but thin-layer loading of the sieves. A reduction in dimensions also promotes the V-shaped arrangement of the individual screens in relation to one another.

In order to keep the performance of a seed cleaner large with small structural dimensions, it is also necessary that the sieves will not become ineffective due to clogging. The innovation therefore provides in a further embodiment that each Sieve an automatically continuously or discontinuously operating cleaning device is assigned to the Coarse sieve is formed by a vibrator and the sorting sieve is mechanically moved in the longitudinal direction of the sieve perforation Has brushes.

A high performance with small dimensions is also dependent on a seed cleaner that the supplied Good electricity does not cut off, but is constantly maintained «, With known seed cleaners, this requirement does not always have to be met because, as is well known, in containers and Very easy to create grain bridges and congestion, which cause blockages, so that the flow of material is interrupted. In a preferred implementation of the new Cleaner is therefore provided that the container and / or the bottom of the material inlet device mechanically with a vibrating Component is connected, and that standing upright on the ground, in

the inside of the container protruding needles are attached, which under the Influence of the introduced vibrations cause a loosening of the material in the container. It is useful if the floor the material inlet device held by a vibrating screen box is.

To complete the seed cleaner is still planned that two high-performance Sohalentrieure -f3ö) ·, which can be operated either jointly or independently of one another, the jacket of which is in two semicircular shells are divided, of which at least one is formed divided along the length, as respective Extension of the two material flow paths behind the main ■ Elevators are arranged side by side under the vibrating sieves.

It is useful if a goods transfer device is on the two main ascenders are connected and connected to the two trieurs, the transfer device being a Adjusting organ and a crop discharge opening, so that the goods optionally with switched off trieurs from the handover equipment removed or optionally with working trieurs can be fed to both or only one trieur »

Due to the new training of the cleaner, high performance can be achieved with a small space requirement of the cleaner. It is by equipping it with trieurs, all work programs that come into being in the preparation of seeds are possible, to meet, especially since the Guteinlaufvorriohtung also a deburrer

can be connected upstream, which carries out a pretreatment of the goods, if this is necessary. There is also the possibility that in practice small amounts of seeds, especially special seeds, have to be treated in the meantime, A particular advantage results from the adjustability of the crop inlet device. Conducive to the versatility The effect is that all air classifiers are equipped with independently adjustable control flaps.

The crop inlet device for special seeds is set in such a way that that only one runoff edge of the roof-shaped floor is effective, while the other by pivoting the floor is pressed against the lower edge of the container. In this way, there is only one of the crop inlet device A veil of goods is released and thus only a single material passage of the cleaner is acted upon with good and in action set. It is thus possible to treat special seeds quickly and carefully without great effort, so that the new seed cleaner can be used in a variety of ways under all circumstances.

An embodiment of the new seed cleaner is shown in the drawings.

The vibrations are from rotating or shaking parts of the cleaner generated and via a mechanical connection, for example by the Frame or the housing, transferred to the bottom 5 and the container 4, so that a constant loosening of the material causes and a constantly uniform veil of material on the Run-off edges 8 is released »

The runoff edges 8 of the base 5 of the inlet device 3 are each arranged in an ascending sifter 10, 11, that is to say a vertical sifter 10 or 11 is assigned to each runoff edge 8. A coarse sieve 12, 13 is attached to each ascending separator 10, 11,

The two coarse screens 12, 13 are arranged parallel to one another, in a shared shaker box and become together driven. The goods falling through them are collected separately in bins 14 and 15 and fed to sorting sieves 16, 17. The sorting sieves 16, 17 run parallel to one another and one above the other in a common sieve box (which is in the Drawings is not shown). The inclination of the two sorting sieves 16, 17 runs in the opposite direction to the inclination of the preliminary sieves 12, 13, so that the two pairs of sieves 12, 13 and 16, 17 are V-shaped to one another, but are housed in separate sieve boxes. To drive the vibrating screens 12, 13 and 16, 17 is a shaft 19 equipped with eccentrics 18, which is connected to a suitable Motor is connected. The eccentric 18 is connected to the individual vibrating screen boxes (not shown) via rods 20 The eccentricity and thus the shaking stroke as well as the speed and thus the number of vibrations of the shaking screen boxes is continuously adjustable within wide limits.

From Fig. 1 it can be seen that the sieve throughput of the pre-sieve 12 is collected in the box 14 and passed over baffles 21 is fed to the sorting sieve 17 in the direction of arrow 22. The sieve throughput of the pre-sieve 13, which is collected in the box 15 is, follows a path in the direction of arrow 23 and arrives

so on the sorting sieve 16. Small ' Impurities, grain too small, but also sand excreted. Each sieve of the two sorting sieves 16, 17 has its own collecting box 24 and 25 for the sieve failure or the impurities on »the sieves 16 and 17 leaves thus largely cleaned seeds with an almost uniform grain size.

Sorting sieves 16 and 17 are used to keep the sieves free equipped with automatically mechanically driven cleaning devices 26, which run in the longitudinal direction of the sieving direction (the arrow 27) are moved back and forth and have brushes that keep the sieves clean. The pre-sieves 12 and 13 have vibrators 28 ', which can be operated continuously or discontinuously work and can optionally be controlled by the cleaning device 26.

The seed that leaves the sorting sieves 16 and 17 still contains so-called. Schmacht- or lesser grain, which is essentially has the required grain size, but not the required grain weight »This grain, but also slight impurities, which have the same size as the grain, are separated from the estate in main ascenders 28,29 » These main ascending separators, which are connected downstream of the sorting sieves 16, 17 are arranged parallel to each other. The main ascender 29 is connected downstream of the sorting sieve 16 is, the material is fed via a chute 30, to which a sieve tray 31 is attached under the wind opening Shaking sieve 17 is followed by a slide 32, which is below

the main ascender 28 merges into a sieve bottom 33. from the cleaned material falls through the sieve bottom 31 or 33 into discharge devices 34 or 35 and is fed from these to a transfer device 36. The transfer device 36 is like this designed that the material optionally through a discharge opening 37 can be withdrawn or fed in together or while maintaining the separation into two material streams trieurs 38 which are arranged lying next to each other under the vibrating sieves. It is in Mg, 1 as a result of the sectional view only one of the two existing trieurs 38 can be seen. The doors can either be switched off or operated together will. The two trieurs can also be operated individually Companies to take into account. In connection with the already described material inlet device 3 can thus be a very cause extensive versatile use of the cleaner. The cleaner can be operated with high power if the material inlet device has the position of the bottom 5 shown in solid lines in Mg. 4, so that two partial material flows can be generated, i.e. two veils of crop are delivered into the ascending separators 10 and 11. Through the cleaning devices 27.28 * sieves are kept free in such an operation, and it very large quantities can be carefully cleaned. A follow-up treatment in the trieurs 38 is appropriate Adjustment of the transfer device 36 possible. Should small amounts of special seeds be treated in the meantime and thus the high performance is not required, then the crop inlet device 3 is changed over, i.e. the

Bottom 5 is transferred into the inclined position shown in dashed lines, so that only one runoff edge 8 is effective can be, while the other comes to the plant on the container 4 and does not allow a delivery of goods. It will be among these Circumstances only the wind sifter 11, the pre-screen 12, the sorting screen 17 and the wind sifter or main ascender 28 are claimed. All other facilities of the seed cleaner are not loaded with material »It is therefore under special circumstances operation at half power is possible.

In the pig. 2 are the ends of the sorting sieves 16, 17 and those connected to these ends or connected downstream of these ends Main ascender 28,29 with the associated facilities shown in an enlarged scale in section »It can be seen that the main ascender 29 connects directly to the sorting sieve .1.6 via the chute 30. But to that Sieve bottom 31 of the main ascender 29 to be able to supply air, must the vibrating chute or the chute bottom 32, which is on, the sorting screen 17 connects to be air-permeable. This is necessary because the two screens 16 and 17 are on top of one another are arranged. For this purpose, a guide device 38 'is switched into the chute 32, which provides unimpeded guidance of the seeds as well as an unhindered guidance of the wind.

In Figo 3, the guide device 38 ^{1 is} shown in plan view. It can be seen that the material can slide in the direction of the arrows 39 over the bottom of the guide device 38 *, but that
