DE2126394A1 - FIELD HARVESTER WITH A CORN PICK ATTACHMENT - Google Patents

Description

Forage harvester with a maize header The invention relates to a Forage harvester with a picking attachment in which the lizards are chopped up with the pistons will.

With such a picking chopper, a picked corn cob can be crushed to maize silage in a single operation. To a proper To achieve fermentation, the crude fiber content is allowed to have a certain proportion Do not exceed dry weight. There is also a large proportion of raw fibers Harmful for digestibility and utilization e.g. in pig fattening.

The problem preceding the invention is therefore the To reduce the proportion of crude fiber.

The object of the invention is achieved in that in the open at the bottom The forage harvester's discharge spout is a number of parallel spaced rows next to each other perpendicular to the manhole cover wall and aligned in the spout axis triangular plates with their acute-angled corners - seen in the direction of ejection - are attached at the front.

The panels according to the invention are made up of fleece components The shredded clippings ejected by the picker are lifted and slide along the cathet side of the adjoining the spout cover wall Panels to the outside.

The sorting out and distraction of the Lizzie is at the same time lowest loss of crushed grain is best achieved with plates, whose Cathets describe a partial circle that is located on the cover wall of the discharge spout nestles best and then narrows in a spiral path.

A very effective defrosting is achieved in an embodiment of the invention achieved by adjoining a row of panels, further panel groups, in which the individual plates are offset from those of the preceding plate group are arranged. The next group of plates can be moved into the front intervene.

Of course, the mouth of the spout is made of plates kept free so that the fleeces are sorted out in front of the wall to be filled Box z-.B. that takes place on a forage wagon.

The invention is shown in the drawing using an exemplary embodiment explained and described in more detail: FIG. 1 shows a picking chopper with a subsequent one Forage wagons; Figure 2 shows a detail of the invention; FIG. 3 shows a section A. - B by the arrangement according to Figure 2.

In Figure 1, a picking chopper 1 is shown with a picking attachment 2, which is attached to the three-point linkage 4 of a tractor 5 via a mounting device 3 is.

A cutting drum 6 of the picking chopper 1 is in the manner of a Hammer mill trained beater bars containing basket plate 7 equipped, where the grains and lizards are further crushed. At the cutting drum 6 closes an ejection chute 8 at the top. This opens into a completely or partially open at the bottom Ejection chute 9. 10 is a chopping wagon attached to the tractor 5.

The discharge spout 9 is - as in detail from Figures 2 and 3 to be seen - with two rows 12 a and 12 b aligned vertically downwards Plates 12 standing parallel to one another are provided.

As can be seen in Figure 1, the panels 12 are so with respect to the end wall 13 of the chopping wagon 10 arranged that the Lieschen - as sketched - in front of the End wall 13 are removed.

i, 7ie can be seen in FIG. 2, describes the one opposite the hypotenuse a Cathete b of the plates 12 has a circle of curvature which is too spiral towards its end narrowed. At the acute-angled corners facing the ejection direction - arrow a - of the plates 12, fleece components are lifted from the grain meal and retained on the cathetus side of the plates 12 a corresponding shortened curvature course Trajectory.

In Figure 3, the lateral offset of the plates 12 b to the plates 12 a to recognize.
