SK347992A3 - Extension of reaping table of combine for collection of rape or bean - Google Patents

Abstract

A front-mounted accessory for combine harvesters (2) for the harvesting of rape or broadbeans has its own cutter bar (1) and a transfer plate (3) which is provided between the latter and the covered cutting unit of the combine harvester (2) and which forms a catching pocket. In order to achieve greater driving safety or driving capability and, above all, a reduction in the grain loss, a preferably vertically adjustable guard plate or sliding plate (6) is arranged underneath the transfer plate (3). Furthermore, the transfer plate (3) has at least two steps (4) which ascend gently rearwards and descend sharply at their rear end.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overhung attachment for rapeseed or horse-bred combine harves, provided with a knife-bar and a transfer plate, a three-way collecting tray and arranged between it and the covered cutting device of the combine.

Since the chopping mechanism of conventional combine harvesters for grain crops does not fully correspond to the plant structure of rapeseed and equine beans, such an offset attachment has been developed * whose own knife beam meets the prerequisites for flawless rapeseed harvesting and the like. As is apparent from its name, it is by means of the transversal transfer of the cut material to the threshing apparatus, whereby the cutting device overlaps it and thus does not cause the cut material to swell on it. However, the piston attachment does not completely satisfy the attached attachments.

It is already known to place a sliding skin under the protective skin (US-PS 4 0 11 709). However, it is used for beveled drive parts for the mowing beam and is not long enough over the entire length of the transfer plate, measured in the direction of travel and is located substantially higher, while additionally protecting, eventually sliding skin associated with the mowing device and adjustable. it has no function.

The rape stalks are largely felted to each other at the time of harvest and the pods burst very easily, so that the seeds then look. Although the existing transfer plate is formed to a certain extent as a trap for premature dropping of seeds, however, during prolonged operation, without raising the attachment, excessive seed accumulation occurs at the step between the blade carrier of the attachment and the transfer plate. results in the dropping of seeds to the ground and thus the loss of seeds. The same applies if the attachment is tilted laterally due to soil unevenness, so that the seeds roll from one side to the other on the transfer plate and then fall off at a larger accumulation. However, it has turned out that the remains of the plants left on the ground can damage the guide plate, thereby causing trenches at the rear end of the transfer plate, i.e. at the beginning of the actual threshing combine, which has to be time-consuming and working. eliminate costs if no overhaul is to be called into question,

The object of the invention has therefore been to improve the oversized attachment so as to minimize seed loss and prevent the transplantation from becoming damaged, and no jamming under the transfer plate should also occur.

The invention has solved the problem by providing, under the transfer plate, a height-adjustable protective, possibly slippery skin, which is known per se, known per se, and that the transfer skin is provided with at least two gradual, steeply descending and descending hind legs.

The protective, eventually sliding plate prevents damage to the transfer plate, plant residues remaining on the ground, while good adaptation to the current conditions is achieved by the height adjustment of the protective, eventually sliding plate and thus even sliding on plant remains. With the help of a protective, eventually sliding plate, it is also possible to prevent emergence and driving of the mowing material by sweeping off the remains of the cut material in front of the actual threshing machine. By the special arrangement of the sliding plate in the shape of a constriction, a greater number of seed collecting spaces already fallen out of the pods are formed in front of the sharp falling back surfaces of the constrictions, thus avoiding too much accumulation of seeds in only one place than hitherto. sheet metal ·

According to a further embodiment of the invention, planes lying in the direction of travel and dividing the space of the cup are placed on the transfer plate. These planes also form a thrust wall in order to eliminate the rolling of all seeds to one side at an inclined position of the transfer skin due to soil unevenness with the above mentioned consequences.

In order to adapt to the current working width of the different mowing machines without making special adjustments to the type of mowing machine, the protective plate and, if necessary, the plate is composed of two or wholly-weaved partial skin pieces of voltable width.

Overview of the drawing in the drawing

BRIEF DESCRIPTION OF THE DRAWINGS The invention is illustrated in the drawing by way of example and in a completely schematic manner, wherein the knife beam, the winch cutting device and the like are omitted for clarity. In the drawing, FIG. 1 shows the parts of a pre-plant attachment essential for the invention in a section lying in the direction of travel, FIG. 2 shows a respective partial cross-section along the line TI-Π in FIG. 1 and FIG. 3 part of the transfer plate r in plan view.

An example of an embodiment of the invention, with the aid of a cutter bar of a front-end attachment and a mower having a cover (not shown), is provided with a transfer plate 2 which is provided with three gradual rearwardly rising and sharp edges at its rear ends. Of course, the transfer plate 2 is bounded laterally by the dashboard and thus forms a bowl. FIG. 1 and 3 it can be seen that on the demonstration plate 2 there are rails lying in the direction of travel and dividing the space of the bowl.

Underneath the transfer plate 2 there is provided a protective or trotting plate 4, which is adjustable in height on the cutting finger guard for the cereal cutting device, since a plurality of superimposed holes for the fixing screws are provided on the fastening joints 2. Protective sliding skin, if any §. it is provided with reinforcements 8 for reinforcement. As shown in FIG. 2, the protective plate 6 and the transfer plate 6 may be composed of a plurality of guiding partial skin parts 2, 3a and 5, wherein the manufacturer stores the sub-plates with a vigorous width to accommodate the current working width of the different cutting threshers.
