Definitions
- the invention relates to a device for harvesting maize or the like. Cereal crops, in particular attachment for combine harvesters or forage harvesters in an embodiment in accordance with the preamble of claim 1.
- the picking rollers have axes of rotation aligned parallel to one another.
- the conicity of the working surfaces of the stalk rollers accordingly creates a passage gap which decreases in width towards the rear base end of the stalk rollers.
- the picking rollers have cylindrical working surfaces.
- the axes of rotation of the stalk rollers diverge towards the front end of the stalk rollers, so that this also forms a passage gap which decreases in width towards its rear end.
- the picking rollers have cylindrical working surfaces and axes of rotation aligned parallel to one another and, accordingly, a passage gap which is constant over its length.
- a cutting device with, for example, a rotating cutting knife can be provided below the stalking rollers.
- the invention is concerned with the problem of creating a harvesting device of the type mentioned, which reduces wear to the Picking rollers in the front area of the passage gap realize a picking process that is particularly gentle on the crop.
- the conicity of the picking rollers can be freely selected while maintaining a desired configuration of the passage gap, from the point of view of specifying a desired throughput speed for the crop through the passage gap and its increase towards the discharge end of the passage gap become. Accordingly, the picking rollers at the front inlet end of the passage gap can be given a relatively small diameter with a correspondingly low circumferential speed during operation, so that the effects on the stalks of the harvested crop begin gently at the start of the passage and the occurrence of slippage with the wear sequence on the front Ends of the picking rollers is lowered.
- the picking rollers can be given a cone angle, which results in a relatively large increase in the diameter of the working group of the picking rollers, which is accompanied by a sharp increase in the peripheral speed of the working surface of the picking rollers towards the discharge end of the passage gap.
- This increase in speed which is preferably about 50%, permits an increase in the harvesting speed with careful picking or a shorter execution of the picking rollers while maintaining the harvesting speed.
- FIG. 1 is a side view of a combine harvester with a harvesting device according to the invention as an attachment
- FIG. 2 is a plan view of the harvester of FIG. 1,
- FIG. 4 shows a picking unit of the harvesting device according to FIG. 2, seen from below,
- Fig. 5 is a side view of Fig. 4, and
- FIG. 6 shows a front view of FIG. 4.
- Fig. 1 illustrates a device 1 for harvesting corn or the like cereals, which forms a header for a combine harvester 2, but can also be combined with a forage harvester or as an independent unit, e.g. as an attachment, can be used.
- the harvesting device is arranged upstream of a conveyor 3, which guides the crop, for example corn cobs, to the processing part of the combine harvester 2, which is supported on the ground by wheels 4.
- the harvesting device 1 comprises in particular a machine frame 5, a transverse screw conveyor 6, covers 7, divider tips 8 and a number of picking units 9, of which FIG. 2 illustrates, for example, four picking units 9. 4 to 6, each picking unit 9 comprises two picking rollers 10, 11, each of which is driven by a gear 12, 13. Above the picking rollers 10, 11, picking plates 16, 17 are provided which are supported by longitudinal members 14, 15, and are rotated inwards in opposite directions above the feed chains 18, 19, which are occupied by drivers 20.
- a chopper 21 can be provided below the picking rollers 10, 11 of a picking unit 9, which chops the stalks of the crop as it is pulled through the picking rollers 10, 11.
- the chopper shown is one with rotating knives 22, but it can also have any other suitable design.
- the picking rollers 10, 11 have feed screws 23, 24 on their front ends and have a conical base body 25, 26 which is equipped with longitudinal webs 29, 30 defining working edges 27, 28.
- the picking rollers 10, 11 arranged on both sides of a picking gap 31 formed by the picking gap 16, 17 run around in the direction of the arrows 32, 33 (FIG. 6) about axes of rotation 34, 35 which point in the direction of travel F and to the front ends of the picking rollers 10,11 are aligned converging.
- the picking rollers 10, 11 can be given a taper which takes into account the desired increase in the peripheral speed of the conical working surfaces which are traversed by the working edges 27, 28 of the picking rollers 10, 11 to the end of the runout of the passage gap 36 can be selected, which is formed between the picking rollers 10, 11.
- the working edges 27 of the one picking roller 10 are each offset from the working edges 28 of the other picking roller 11, and the working edges 27, 28 define the passage gap 36 with the least amount when passing through the angular position Distance to the roller body 25, 26 of the adjacent picking roller with its outer surface.
- the width of the passage gap 36 defined in this way between the picking rollers 10, 11 can be approximately 6 to 15 mm, preferably approximately 8 to 12 mm, at the front ends and approximately 2 to 10 mm, preferably approximately 3 to 6 mm, at the base ends.
- the working edges 27, 28 of both picking rollers 10, 11 can run flush with each other when passing through the angular position with the smallest distance to the working surface of the adjacent picking roller and thereby limit the passage gap 36 between them.
- the passage gap 36 between the picking rollers 10, 11 can have a substantially constant width of approximately 1 to 10 mm, preferably approximately 3 to 5 mm.
- the base bodies 25, 26 of the picking rollers 10, 11 have a conical outer surface, and the webs 29, 30 that present the working edges 27, 28 have a height that is constant over their length, so that the working surfaces of the picking rollers 10 defined by the working edges 27, 28 , 11 surrounds the lateral surfaces of the base bodies 25, 26 conically at a distance.
- the working surface diameter at the front end of the picking rollers 10, 11 is approximately 75 to 125 mm, preferably 90 to 110 mm.
- the length of the picking rollers is generally between 400 and 600 mm.
