Front cover header

description

The invention relates to a header with a support frame which comprises a central part and two articulated on the central part, each movable by a hydraulic cylinder between a horizontal working position and a raised transport position, and on the central part and on the side parts attached elements for receiving and conveying plants.

State of the art

On self-propelled harvesters, harvesting attachments are used to harvest and bring in crops. Due to recent increases in the performance of harvesting machines, ever wider harvesting heads are used. While harvesters for combine harvesters are usually rigid and separated from the combine harvester for road transport and placed on a trolley, corn harvesters for combine harvesters and corn headers for forage harvesters are usually designed to be foldable. However, there are also foldable cutting units for combine harvesters. For road transport, outer side parts of the harvesting attachments are pivoted into a transport position, usually upwards or inwards. The foldable harvesting attachments remain attached to the front of the harvester during road transport.

EP 20 20 172 A1 describes a harvesting attachment with side covers which are drivingly coupled to the upwardly pivotable side parts of the harvesting attachment, so that the pivoting drive of the side parts brings the side covers into a rest position behind the side parts when the side parts are in their lowered harvesting position in a forward-facing position that covers the crop header to the side when the side parts are raised to their transport position.

However, in the case of road transport, it is also sensible to cover the header from the rear in order to warn road users and to protect them from contact with the relatively pointed elements, in particular mowing devices of the header. In the prior art, devices covering the crop header towards the front are attached to separate undercarriages (EP 1 668 972 A1), which serve to support the header during a road trip and are to be removed again before harvesting, or they are removed from the

BE2016 / 0051

The driver of the harvesting machine is attached and removed manually, which is relatively time-consuming since the driver has to get out of his cabin to do this (see the film http: // m. Youtube. Com / watch? V = 47C982cV7lg).

task

The object on which the invention is based is seen in providing a harvesting attachment with side parts which can be moved into a transport position and a front cover which can be easily attached.

According to the invention, this object is achieved by the teaching of patent claim 1, features being listed in the further patent claims which further develop the solution in an advantageous manner.

A harvesting attachment comprises a support frame which comprises a central part and two side parts articulated on the central part and each movable by a hydraulic cylinder between a horizontal working position and a raised transport position and on the central part and on the lateral parts for receiving and conveying plants. A cover is movably attached to the middle part, which is coupled to a drive which is set up to position the cover on the rear of the header when the side parts are in the working position and on the front of the middle part when the side parts are in the transport position.

In this way it is achieved that the driver of the harvester no longer has to get down from his workplace in order to attach the cover. Rather, this is powered by a drive between a protected position on the back of the middle part, which does not adversely affect the harvesting operation, which it occupies when the side parts are in the working position, and a position covering the middle part which it occupies when it is in the working position the side parts are in the transport position.

Embodiments

In the drawings, two exemplary embodiments of the invention described in more detail below are shown. It shows:

BE2016 / 0051

1 is a plan view of a header according to a first embodiment, the left half of which has a side part in the transport position and the right half of which has a side part in the working position,

2 shows a top view of the header of FIG. 1, the left half of which has a side part in the transport position and the right half of which has a side part in an intermediate position,

Fig. 3 is a plan view of a header according to a second embodiment, the side parts are in the transport position, and

4 shows a rear view of the header of FIG. 3.

FIG. 1 shows a first embodiment of a harvesting attachment 10 according to the invention. It comprises a support frame 12 which has a central part 14 and at the outer ends of the central part 14 pivotable articulated side parts 16 about axes 20 running in the forward direction. The middle part 14 and the side parts 16 each carry a number of elements 18 for receiving and conveying plants in the form of mowing and feeding devices, which in the embodiment shown are suitable for harvesting stalk-like crops (maize). By means of hydraulic cylinders, not shown, the side parts 16 can be pivoted upward from the horizontal working position, as shown in the right half of FIG. 1, into the transport position shown in the left half of FIGS. 1 and 2. The right half of Figure 2 shows an intermediate position between the working and transport position. The swivel angle can be 90 ° or more. The harvesting attachment 10 then remains fastened to the front of the harvesting machine carrying it (e.g. combine harvester or forage harvester) on the road.

For safety reasons, a cover 22 is provided, which is located in the working position on the back of the header 10, namely on the back of the side part 16 and is positioned in the transport position on the front of the middle part 14 in front of the mowing and feeding devices attached to it covers them towards the front. The cover 22 can be equipped with doublets. The cover 22 is attached to the central part 14 of the support frame 12 by means of a first, outer arm 24 and a second, inner arm 26. The first arm 24 is in each case about a vertical pivot axis 28

BE2016 / 0051

Middle part 12 and pivoted about a vertical pivot axis 34 on the cover 22 and carries at its outer end a warning lamp 36. The second arm 26 is pivoted about a vertical pivot axis 30 on the middle part 12 and about a vertical pivot axis 32 on the cover 22 . The arms 24, 26 form a kind of parallelogram guide for the cover 22, so that when the arms 24, 26 are pivoted by approximately 90 °, the arms 24, 26 essentially cause the cover 22 to be displaced forwards and backwards in parallel, as in the figures 1 and 2 is shown. The arms 24, 26 can be pivoted by a separate, power-operated drive or by coupling to the hydraulic cylinder, which pivots the side parts 16 about the axes 20, comparable to the arrangement described in EP 20 20 172 A1. The arms 24, 26 and the cover 22 remain below the side parts 16, i.e. they are only moved forward when the side parts 16 are at a sufficient height to avoid a collision.

FIGS. 3 and 4 show a second embodiment of a header 10. Elements which correspond to the first embodiment are provided with the same reference symbols. The cover 22 'is designed as a flexible material (e.g. as used for truck tarpaulins), provided with warning markings and wound on a reel 40. The reel 40 extends vertically and is attached to two arms 44, 46 which are rotatably mounted about a vertical axis 42 in the middle of the middle part 14 of the support frame 12. The lower arm 46 is located below the middle part 14 of the support frame 12 and is connected to the lower end of the reel 40 via an extendable actuator 48. The upper arm 44 is located above the middle part 14 of the support frame 12 and is connected to the lower end of the reel 40 via an extendable actuator 48. The upper arm 44 is cranked or curved in an S-shape, so that its pivot bearing is located lower than its actuator 48. The upper arm 44 is connected by a further support 54 to brackets 50 which are attached to the middle part 14. The carrier 54 is used to hang the header 10 on the feed housing of the harvesting machine, which moves the header 10 across a field. FIGS. 3 and 4 show the header 10 with the side parts 16 brought into the transport position. At the front, outer edges of the side parts 16, corner profiles 52 are attached, which can be equipped with warning lights in their upper areas.

One end of the cover 22 'is fixedly connected to the central part 14 by a vertically extending holder (not shown). If the side parts 16 are in the working position,

BE2016 / 0051, a separate power-operated drive (not shown) brings the arms 44, 46 into a position in which the reel 40 is located directly adjacent to the holder mentioned. The actuators 48 are retracted. The cover 22 'is then wound on the reel 40 and is in a position which is not disruptive during harvesting. If, however, the header 10 is to be transported on a road, the actuators 48 are extended synchronously and uniformly after the side parts 16 have been swung up, and then the arms 44 and 46 are rotated together and simultaneously by 180 ° around the front of the header 10 by the power-operated drive mentioned . Eventually the

Arms 44, 46 are retracted by actuators 48 to tighten cover 22 '. The sides and front of the header 10 are thus wrapped by the cover 22 '. The changeover for a harvesting process takes place in reverse. The cover 22 'is wound onto the reel 40 by a spring (not shown) or a further drive (not shown).
