Description

Field of application of the invention

The invention relates to a wide-cutting attachment for introducing Halmfutter, in particular of silage maize, which is connected to the feeder of a forage harvester or a combine harvester.

Characteristic of the known state of the art

For introducing Halmfutter various attachments (adapters) are known. On the one hand there are attachments with frontal alternating mowing, which are e.g. in the HU-PS 162549 or in the CH-PS 426432 are explained. On the other hand, the multi-row implements are to be mentioned, among which the following different types can be distinguished:

- Attachments in which the cutting with rotating or alteni nierendem Schneid "verk made and while the Erntegutförderung done in rows arranged chain pairs (eg, the attachment according to the HU-PS 171413).

- attachments where trimming is carried out with rotary trimmers, while the crop is conveyed in rows, each with a chain,

- Attachments in which the cutting is done with a cutting unit with each counter-blade for each row, while the crop is conveyed with a special conveying element (eg HU-PS 188 005).

- attachments in which alternate crop cutting or per row is done with a special cutter mounted on a screw, while crop feeding takes place with a screw conveyor (e.g., HU-PS 175650 and 178941).

A particular group of frontal cutting attachments are those attachments where the cutting is done with a rotary cutter high speed and without counter blade, while the Emteugutförderung with special (possibly controlled) low-speed conveyor elements is an example of this can DE-OS 3406551 and DE-OS 3340820 may be mentioned.

The advantage of the attachments with frontal alternating mower is in crop cutting the full width, making this attachment to the Reihenabs'andsänd vungen the crop is not sensitive and the problems with the exact consequences of the rows do not occur.

However, this attachment has the disadvantage that as a result of the simultaneous application of a Zufördergurtes and a transverse auger the cut crop randomly gets into the chaff, whereby the Häckselmaß (chop length) is uneven, which in turn is disadvantageous in livestock feeding. Another disadvantage of this design is that its mower deck and its drive are complicated and the specific gravity of such an implement is too great due to additional elements (eg reel).

The advantage of the möiirreihige attachments (row adapter) bes'eht that as a result of the row-wise Erntegutförderung after cutting, dis homogeneity of emerging from the shredder shredded material is cheaper. In addition, the multi-row attachments with rotary cutter have the added advantage that they are simple and can be manufactured with a low specific weight.

However, all previously known multi-row implements have the fundamental disadvantage that their cutting is sensitive to the changes in the row spacing of the crop, which requires a precise consequences of the rows durcn the harvester. If these conditions are violated, the technological reliability of the attachment is severely impaired.

There are implements that tried to combine the advantages of the two types of attachments (multi-row or frontal cutting), but only partially succeeded.

These solutions have the advantage that they allow a frontal cutting, but they also have significant disadvantages or lack due to their structural design.

Cutting without a counter knife requires a high speed, while the Ernteguiförderung requires a deviating, low speed, as a result, the gear used is quite complicated. Another disadvantage arises from the high specific energy requirements, which is generally characteristic of the rotary trimmers without counter knife.

These solutions can be used primarily on suspended and towed base machines.

Object of the invention

The aim of the invention is to increase the utility properties of implements of the generic type in a cost effective manner.

Explanation of the essence of the invention

The object of the invention is to develop a wide-cutting attachment for introducing Halmfutter, in particular silage maize, which is insensitive to the changes in Erntegutreihenabstandes and the inaccuracies of the series connection, at the same time ensures a favorable direction of the feed of the cut crop in the transverse screw conveyor a uniform Hächselmaß (chop length) can be achieved and that the attachment is structurally simple and therefore can be made with low specific weight.

The above object is achieved in an attachment that has cutters, Halmteiler, Harvest "An'lou with crop conveyor elements and a crop cross auger, according to the invention thereby solved, the cutting units of the attachment dais provided with cutting elements rotating-cutting discs and These discs associated, each disc two or more interfaces forming counterblades and this associated Halmzuleitelementen and special arcuate channels consist, the crop conveying elements in the cutting zone are synchronous with the respective rotating cutting disc, the cutting elements are guided and driven below.

embodiment

The solution according to the invention will be explained in more detail in an embodiment with reference to the accompanying drawings ί. Show it:

Fig. 1 shows a typical embodiment of the invention A nbaugerätes, which is connected to the Einzugss / stem, ie to the feeding device 1 of a self-propelled forage harvester.

The attachment has in a conventional manner Halmteiler 2, a crop cross auger 3 and a drive 4. It is characteristic of the attachment according to the invention that his reapers from ienten with 5 Schneckenier provided rotating cutting wheels 6 and this associated, each disk two or more interface η forming counter blades 7 are made. At each cutting the Gcyciiklingen 7 a apt Halmzuleiteiemeite 8 and special arcuate channels 9 are provided, their training in particular in Fig. <. jut is evident. Fig. 2 shows the assembly of a pair of cutting units according to the invention, while Fig. 1 represents the possibility of expansion of the working width dui on demand.

From Figs. 1 and 2 it is clear that the cutting elements 5 are followed at a certain distance on the same track v.n crop conveyor elements 10 at the same speed.

The operation of the wide-cutting attachment according to the invention is as follows:

The straw feed to be introduced is ordered and guided by the straw feeders 8, and in the case of the tall crop, the crops are supported by the straw dividers 2 and tilted in the direction of material flow. The crop is by the arranged in the width of the attachment cutting units whose direction of rotation is indicated in the drawing with arrows, with the aid of the rotating cutting blades 6 mounted cutting elements 5 unci the associated, each disk two or more interfaces forming counter blades 7th cut off in the entire width of the attachment.

The same speed with the rotating cutting disc having crop conveying elements 10 promote the crops cut through the special arcuate channels 9 in the crop cross auger 3. The rotating the cutting discs 6 associated special arcuate channels 9 are designed so that the direction of The crop material exiting from these channels almost coincides with the conveying direction of the crop cross conveyor screw 3, so that the crop passes in an ordered state into the feeding device 1 of the following basic machine denoted by arrows.

In the illustrated embodiment, the attachment according to the invention is shown with a straight Reiherizahl and following by a crop cross auger to the basic machine, but in suspended or towed basic machines with odd number of rows is also such a variant vorsteNbar, in which the attachment with its cutting directly to the feeding device of the basic machine is connected.
