Abstract
A front attachment for use with combine-harvesters when used to harvest rape or horse beans or similar crops comprises a separate cutter bar and a bridge plate, which extends between the cutter bar and 9 covered cutting mechanism of the combine-harvester and constitutes a collecting trough. To provide a higher safety of travel and an improved travel performance and particularly to reduce the loss of grains, a guard plate or slide plate, which is preferably adjustable in height, is provided under the bridge plate. Additionally, the bridge plate has at least two steps which are gently rearwardly and upwardly inclined and sharply decline at their rear end.
Description
This invention relates to a front attachment for use with combine-harvesters when used to harvest rape or horse beans or similar crops, comprising a separate cutter bar and a bridge plate which extends between the cutter bar and the covered cutting mechanism of the combine-harvester and constitutes a collecting trough.
Because the cutting mechanism of a conventional combine-harvester intended for harvesting grain is not fully satisfactory for harvesting rape or horse beans or crops having a similar structure, front attachments have been developed, which have a separate cutter bar, which can effectively cut rape or the like. A bridge plate ensures a satisfactory transfer of the cut crop to the combine-harvester, particularly needed because the cutting mechanism of the combine-harvester is shielded and cannot restrain the cut crop. However, the known front attachments are not fully satisfactory.
It is known (U. S. Patent 4,011,709) to provide, under the bridge plate, a guard plate or slide plate, and to provide the bridge plate on a much higher level. The guard plate or slide plate, serves to protect the means for driving the cutter bar and does not extend over the overall length of the bridge plate, measured in the direction of travel. Additionally, the guard or slide plate is connected to the cutting mechanism, is adjustable and does not have a function with respect to the bridge plate.
Rape plants are highly felted during the harvesting season and their pods tend to burst easily so that the grains then fall out of the pods. The previously used bridge plate is designed to constitute a trough for collecting the grains which have prematurely fallen out.
i _2-i However, operation~o~
a combine-harve ter with the previous bridge plate and a~tachmeut time in which the for a lon attachment was not~lifted in an accumulation would resul of an excessive amounts of grains at the tep between the cutter bar of the attachtn~nt ate so that grains and the bridge would fall over tojthe be lost. It has ground and woul also been found that plants which remain the stumps of the on the ground may to and that material damage the bridge p1 may build up under bridge plate, i.e_, jthe rear end o~
the at the front erid er proper and such of, the combine-harves built-up material a considerable mast be removed with expenditure of time~and r operation is to work if a prop be continued. !
For this ~eaeon, it ct of the invention is an obj to improve the knowr~ that the loss of Front attachment grains will be minim i.zed, damage to transfer plate will I the be prevented, and ~build-up of rnateriaunder the transfer a plate will be avoided.
The objects set forth l.ished in accordance ~.B acco Zo with the invention or slide plate is i~ that. a guard plat provided below the bridge plate bridge plate and the comprises at least steps, which tyro rearwardly risin sharply decline from, their rear edges.
In particular according present invention to th there is provided use With combine-a front attachment fo harvesters when used~to harvest rape or ~or~ae beans or similax crops, comprising a separate cut er bar and a bridge plate, which extends'Ibetween the cutter ar and a covered cutting mechanism of the combine-harvest r and constitutes a collecting trough, characterized in that a guard plate or -2a-slide plate is pr ided below the bri ge plate and the bridge plate cotapr ses at xeast two r arwardly rising steps, which sharply decl~~.ne from theix rear edges.
The guar. plate or glide p1 to wiil prevent damage to the bridge plat by plant stumps w ich remain oa the .. ground and, becausl the guard plate o slide plate Can be adjusted in height, it can be adapted o the current conditions and thellguard glate or slid plate may even slide on the plant stumpsl. The, guard plate r slide plate wzll also ensure that a retention of crop r sidues, which may occur in front of t a combine-harvests props= and may i I
I
i ~ CA 02083540 2002-03-19 obstruct the travel, will be avoided. Owing to the special design of the bridge plate with steps, several spaces for collecting the grains which have fallen out of the burst pods will be provided in front of the sharply declining rear surfaces of the steps so that an excessive accumulation at a single point, as occurred in the previous practice, will be prevented and the loss of grains fallen from the bridge plate will be minimized.
According to a further feature of the invention, the bridge plate is provided with ribs, which extend in the direction of travel and divide the space in the trough.
Such ribs also constitute retaining walls, which when the bridge plate assumes an inclined position owing to an uneven ground will prevent a rolling of all grains to one side, with the described consequences.
To permit an adaptation to the working width of various combine-harvesters without the need for manufacturing special attachments for each combine-harvester, the guard plate, and optionally also the bridge plate, is composed of two or more juxtaposed plate segments having selectable widths.
The subject matter of the invention is strictly schematically shown by way of example in the drawing, in which the cutter bar, cutting mechanism, reel and the like have been omitted for the sake of clearness and in which:
Figure 1 is a sectional view taken on a plane extending in the direction of travel and shows those parts of a front attachment which are essential for the invention, Figure 2 is an associated partial transverse sectional view taken on line II-II in Figure 1 and ~ CA 02083540 2002-03-19 Figure 3 is a top plan view showing a bridge plate.
A bridge plate 3 extends between the cutter bar 1 of the front attachment and the combine-harvester 2, which has a covered cutting mechanism, not shown. The bridge plate 3 comprises three gently rearwardly and upwardly inclined steps 4, which sharply decline at their rear edges.
The bridge plate 3 is obviously limited on either side by a side wall to form a trough. It is apparent from Figures 1 and 3 that ribs 5 extending in the direction of travel, are provided on the bridge plate 3, and divide the tray space.
A guard plate or slide plate 6 is provided below the bridge plate 3 and is vertically adjustably mounted on the finger guard 7 for the grain-cutting mechanism by means of a plurality of fixing screws extending through superposed bore 9 for fastened by fixing lugs. The guard plate or slide plate 6 is stiffened by beads 8. As is apparent from Figure 3 the cutting mechanism and the bridge plate 3 may be composed of a plurality of juxtaposed plate segments 3b, 3a, 6b, 6a and plate segments differing in widths may be kept in stock by the manufacturer to permit an adaptation to different working widths of different combine-harvesters.
Because the cutting mechanism of a conventional combine-harvester intended for harvesting grain is not fully satisfactory for harvesting rape or horse beans or crops having a similar structure, front attachments have been developed, which have a separate cutter bar, which can effectively cut rape or the like. A bridge plate ensures a satisfactory transfer of the cut crop to the combine-harvester, particularly needed because the cutting mechanism of the combine-harvester is shielded and cannot restrain the cut crop. However, the known front attachments are not fully satisfactory.
