Description

Shakerless self-propelled combine harvester

The innovation concerns a shaker-free one
self-propelled combine with threshing drum
and several behind it in the direction of transport
Separating drums arranged parallel to one another, each of which has a separating element provided below the same in the form
a perforated, trough-shaped bent sheet metal [■ is assigned. <

For self-propelled combine harvesters, more conventional:

Design, namely with a concave and p

Threshing drum existing threshing device?;

and subsequent tray shakers are grain?

Loss measuring devices known. Vie, for example, the DE-OS 15 82 656 disclosed,
are doing the grains through a back
The funnel provided for the rack shakers is collected and passed through a downpipe onto a membrane. The number of per unit of time; impinging on the membrane grains provides ι then a point of reference for the grain loss is. | Behind the last separating drum of ■ straw walker-less combine harvesters, however, such devices cannot be used,
because through it, there the straw and the grain
not falling down freely, but from the
Separation drums to the rear with high energy
is thrown out, an increased risk of clogging is to be expected.

The invention is therefore based on the problem of creating a combine harvester of the type specified in the introduction which satisfactorily fulfills the requirements to be placed on it with regard to reliable grain loss measurement. This is achieved according to the invention in that a grain loss measuring device is arranged below a separating element. This loss grain measuring device is preferably arranged below the last separating element in the conveying direction. According to a further essential feature of the innovation, the loss grain measuring device consists in a simple manner of a baffle plate extending almost over the entire width of the separating element, which on the side opposite the impact side with a large number of ^{similar elements}

Structure-borne sound microphones is occupied. It is It is recommended that the baffle plate be connected to the separation element via vibration dampers.

In practice it has proven to be advantageous

1 pointed when the baffle plate at an angle of minus 30 to plus 60 degrees, preferably 0 degrees is arranged to the vertical just below the last separating element.

\ In the following, the innovation will be based on a yyy

Embodiment and two of this schematically depicting figures explained in more detail will. It shows: |

and

Figure 2 shows the rear circled part of Figure 1 in an enlarged view.

With 1 the side walls of a combine harvester are referred to, in which both the threshing drum 2 with the associated threshing cort) 3 as well as six separating drums behind the concave 3 in the conveying direction 4 are stored. Separation elements which are curved in the shape of a trough are located below each separation drum 4 5 arranged, which consist of metal sheets provided with elongated holes 6 in their separation area, which are parallel to the axes the separation drums 4 running friction strips are occupied. The two end faces of each separation element are used for stabilization 5 firmly connected with side boundaries 8 designed as a support. The one below the last Separating drum 9 arranged separating element

has elongated holes 6 arranged in rows on its material receiving side and is connected to it formed over the entire surface towards the product delivery side. In the area of the last row of slots in the direction of crop flow a baffle plate 10 is provided below the last separation element 5, which , on its opposite side from the impact side

Side with structure-borne sound microphones 11 is occupied. About bracket 12, which is between the microphones are firmly connected to the baffle plate 10, the latter are attached to rubber spring elements 13, the rubber spring elements 13 in turn via further brackets 14 with one with the separation element 5 welded plate 15 screwed
