Cleaning device; for combine harvesters

The innovation concerns a combine harvester, in particular self-propelled Combine harvester, with an upper sieve and an adjoining one Upper sieve extension, a guide plate being arranged below the upper sieve extension to which a the goods falling through the upper sieve extension Tailings snow adjoins the guide floor, and a further guide floor is arranged above this guide floor is the material that falls through the upper sieve Grain snail heads.

For combines that have an upper sieve, an upper sieve extension and a lower sieve are provided, for example When threshing rye, barley or wheat everything that falls through the upper and lower sieve into the grain auger and from there into the grain tank, because the material that has fallen through is all clean grain. Everything that falls through the upper sieve extension gets into the returns auger and is used for another threshing process subject, because at this point the grain is still mixed with parts of the ear and chaff.

Should other grains be threshed instead of rye, wheat, barley or oats, such as beans, peas, for example or corn, it is found that only the grain falls through the upper sieve extension because the holes in the upper sieve extension are so small that the pods of beans and peas or the cobs of corn do not fall through be able. This grain would now be fed to the returns auger and then passed through the threshing system again,

as a result of which the goods, which have already been threshed out cleanly, are considerably damaged and the machine is unnecessarily dirty.

To avoid this, it is common to conduct a available as an additional part ^s sheet falling through the Obersiebverlängerung crop flow instead of tailing auger directly to the grain auger.

Apart from the fact that the Gutleitblech in known combine types is only supplied as an accessory for the maize threshing and therefore for the standard combine harvesters The pea and bean shower is not available at all, the time required for installation and removal such baffles considerably.

The present innovation is therefore based on the Aufgate, to create a combine harvester of the type described in more detail at the outset, which meets the requirements to be placed on it, in particular with a view to a practicable possibility dsr optional supply of the falling through the upper sieve extension Good things for the returns or grain tank auger.

This is achieved in a combine harvester of the type described in more detail in that the guide plate is attached to both the lower and is also connected to the upper guide floor. on The baffle plate is structurally simple at its end facing away from the lower guide base via a hinge pivotally attached to the combine. Aaderenends is the baffle about a. Actuating linkage with one of the two guide floors for the purpose of pivoting the guide plate from the lower one Guide floor connected to the upper guide floor. To ensure a clean connection of the swiveling guide plate to the To reach the guide floor, the guide plate is stepped at one end. According to a different design proposal is everyone Guide bottom a transverse to the direction of travel of the combine harvester attached to the rear frame part guide for assigned to one-end storage of the guide plate. With one like that

trained combine, it is possible to move the baffle gradually to be adjusted in height so that it is supported on the one hand in the lower guide and on the lower guide base and in the other position on the upper guide floor and in the upper guide.

In the following, the innovation is to be explained in more detail using an exemplary embodiment and a single figure that shows it schematically. The actual threshing elements, which consist of the concave, the threshing drum and the turning drum, are denoted by 1. The more or less clean threshed crop arrives on the preparation floor 2 and from there to the upper sieve 3. Here the threshed crop is sifted out. Light chaff particles are blown away by the fan 4 and the clean material falls onto the lower sieve 5, where it is subjected to another cleaning process by the air from the fan 4. The upper guide floor 6 then conveys the grain to the grain auger 7 »from where it arrives in a grain tank (not shown). Crop material mixed with impurities, which neither fell through the upper sieve 3 nor was blown away by the blower wind, migrates from the upper sieve 3 to the upper sieve extension 8 connected to it and is sieved out one more time. The sieved part then slides over the guide plate 10 and the lower guide floor 9 to the tailings auger 11, the rest falls onto the arable soil. Rye, barley, oats and wheat, for example, are threshed in the manner described here. However, if corn, peas or beans are to be threshed, the guide plate 10, which is attached to the frame part 13 via a hinge 12, is pivoted to the upper guide base 6 and thus completely blocks access to the tailings auger 11. The pivoting itself takes place via a hand lever 14 which is welded onto a shaft 15, which in turn is fastened in two to the guide base 9

Consoles 16 stores. With the shaft 15, a link 17 is also firmly connected, which is facing away from the shaft 15 at its The end is in communication with the guide plate via a lever 18. In the, in the drawing with dashed The position of the guide plate 10 shown in the lines, the combine harvester is switched to beans, peas or corn threshing. The This means that the crop that falls through the upper sieve extension is also not, as is the case with rye threshing, for example but fed directly to the grain auger 7 to the return auger 11. By means of this innovation in accordance with the design of the guide plate 10 eliminates the cumbersome and time-consuming assembly of a cover plate for the returns auger 11, such as this has been common practice with maize, beans and pea threshing.
