DE1012771B - Arrangement of combine harvesters provided with a shredding device for the straw - Google Patents

Description

The invention relates to an arrangement on combine harvesters provided with a shredding device for the straw. The invention is mainly characterized in that the shredding unit for the straw about a substantially vertical axis at or near the one. Long side of the combine is pivotably mounted so that the unit, hanging in the warehouse, can pivot sideways outward from its working position under the straw outlet. Compared to known shredding devices for the straw carried by the combine harvester, the new arrangement according to the invention makes it possible to make the straw walkers easily accessible through the straw outlet and parts required for control of the cleaning device, the sieve plates of which are usually closed by a rearward opening flap are exposed.

The invention and other advantages associated therewith are noted below described on an embodiment illustrated in the drawing.

1 shows a combine harvester provided with a shredding unit according to the invention in FIG a view against the straw outlet;

Fig. 2 shows, seen from the side, the rear part of the combine harvester with the arranged thereon Shredding device for the straw;

Fig. 3 shows on a larger scale a locking device visible on the right side in Fig. 1, while

Fig. 4 the same locking device seen in the direction against the side wall of the combine harvester shows.

In the drawing, 1 denotes the frame of the combine harvester, while 2 denotes running wheels, which in the example shown also serve as steering wheels. The straw shaker of the combine harvester is denoted by 3 and the straw outlet by 4 and the mouth of the latter with 4 ', while 27 denotes the space occupied by the cleaning device. 5 with a box-shaped, upwardly open housing for the comminuting members is referred to, which housing has a downwardly and rearwardly directed outlet 6. The crushing members for the straw can consist of rollers 8 provided with knives or the like, which are arranged on shafts 7 which, in the housing, for. B. in a reinforcing beam 9 which surrounds the latter, are stored. Arranged on one shaft 7 is a belt pulley 10 for a belt 11 driven by a drive mechanism of the combine harvester, which belt also runs over a tensioning roller 12 which is also carried by the housing 5, 9.

The shredding unit is by means of bearing pins 14, 15 in on one long side of the combine harvester frame provided bearing tubes 16 or the like. The: formed by the cones The pivot axis for the unit 5 to 9 is arranged essentially vertically, so < that the unit can swivel backwards and outwards from the straw outlet. During this pivoting movement, the slackens Belt 11, so that it can be removed or in case it is ineffective to prevent accidents. In this pivoted-out position, the straw outlet is completely exposed, so that the cleaning device becomes accessible. The straw walker can now be overlooked and any straw blockages removed, with the rear one Control members and bearings provided at the end of the shaker corrected or overlooked and lubricated can be.

If required, there can be: s unit 5 to 9 in the swiveled out position are lifted by the pins 14, 15 are only loosely guided through the bearing tubes.

In his grappling position under the straw spout the shredding unit is operated by means of a bearing pin on the opposite side arranged locking device set, which in the example shown consists of a on the housing 5 attached flange 18 as well as from an angle iron 20 attached through this and an angle iron 20 attached to the straw outlet guided locking pin 21 consists.

Stroha, outflow attached tongue 19 with a recess for the flange 18 is provided behind the pin.

The pivot pins 14,15 are in the example shown with the housing 5, 9 of the Zerklemerungsvorrichrung connected by diagonal struts. A pair of such struts, designated 22 and 23, extend in the position of use mainly in the longitudinal direction of the combine, while a another pair of struts 22 ', 23' sloping rearwardly inward towards the central part of the housing 5.9 extend. An upper strut 24 can are provided, which when attaching a screwed nut 25 for setting the Height of the rear edge of the housing 5, 9 can serve.

Claims (3)

Patent claims: 1. Arrangement of combine harvesters equipped with a shredding device for the straw, characterized in that the shredding unit for the straw about a substantially vertical axis at or near the one long side of the combine is pivotably mounted so that the unit, hanging in the warehouse, can swivel sideways outward from its working position under the straw spout to the rear of the straw walker and the cleaning device are easily accessible do. ■ 2. Arrangement according to claim 1, characterized in that the shredding unit on Pin is suspended in such a way that it is only in the pivoted-out position from Combine can be lifted off. 3. Arrangement according to claim 1 or 2, characterized in that the pivot bearing on that Side is on which a driving pulley is provided for the shredding links so that the belt can be slackened and lifted when the unit is in swiveled out position.
