Description

[0001] The present invention relates to a device used for moving harvested crops lying on the ground, according to the preamble of claim 1.

[0002] In general, a rake is an agricultural implement used to gather harvested crops such as hay and / or straw, as well as green fodder, into uniform swaths, also known locally as windrows, rows, or lines. These can then be picked up by a forage harvester, such as a baler, a loader wagon, a forage harvester, or similar equipment.

[0003] In addition, the harvested crop is also shaped in this way in the evening to better protect it from the night dew and to allow the ground to dry better in the morning before the harvested crop is then evenly distributed on the ground again with the hay turner so that it can continue to dry.

[0004] Such devices, insofar as they are known from the prior art, have the disadvantage that the rakes are generally very maintenance-intensive, damage the crop, and contaminate it. The belt rake significantly reduces forage contamination and crop damage, but is uneconomical for many farms because the price is very high and a great deal of technology is incorporated; this combination makes these belt rakes very expensive.

[0005] It is therefore an object of the invention to provide a device for moving harvested crops which is designed in an alternative or better way compared to the prior art, for example by using a lower-maintenance technique or by having a cleaning effect on the harvested crop.

[0006] This is achieved according to the invention by a device according to claim 1. Advantageous embodiments are claimed in the dependent claims.

[0007] The invention relates to a device for moving harvested crops. The device is pulled or pushed by a tractor or similar vehicle and is used for moving harvested crops located on the ground surface. The device essentially consists of a conveying unit arranged transversely to the direction of travel and close to the ground, an adjoining enclosed interior space, which serves in particular for lateral conveying, and a suction-pressure blower. The components described are all attached to or mounted on a support frame. The support frame achieves its ground-adaptability through the sliding shoe support frame. According to the invention, the harvested crop is conveyed within the enclosed interior space by the pressure conveying function, the suction conveying function, or a combination of the pressure conveying and suction conveying functions of the suction-pressure blower.The pressure conveying function works by transporting compressed air from the suction-pressure blower to a point on the housing, for example, above the conveying device, and blowing it into an interior space. The suction conveying function works by the suction-pressure blower drawing air and crop material out of the interior space through an opening on the interior, for example, at the suction air inlet.

[0008] Using such a device, a gentle, efficient, and clean harvesting process can be achieved. The suction-pressure blower ensures that the forage is transported gently and effectively. This is particularly important during haymaking, as the crop is very dry and brittle. The gentle conveying action of the suction-pressure blower minimizes the risk of damaging the crop and thus prevents any loss of quality.

[0009] A conveying device can be, for example, a pick-up. The pick-up conveys the harvested crop using rotating spring tines.

[0010] The conveying device transports the harvested crop lying on the ground surface, for example in a field, into the interior. From there, the harvested crop is conveyed to the harvested crop outlet by means of incoming compressed air and the suction effect of the suction-pressure blower.

[0011] According to one embodiment, the device is equipped with a crop separation device, which can be, for example, a perforated plate. This device separates the crop contained in the airflow, which flows from the interior into the suction-pressure blower, and releases this crop, preferably as a swath, onto the ground surface, for example, a field, via a crop outlet. This creates and utilizes a continuously circulating airflow. This swath can then be loaded, for example, with a forage wagon.

[0012] According to another version, the suction-pressure blower does not require a precisely defined position on the housing, as both the compressed air outlet and the suction air inlet of the blower can be connected to the interior, for example, via hoses. This is particularly advantageous for maintaining flexibility and avoiding obstructions when working at larger widths.

[0013] Preferably, mounting brackets are provided on the support frame to attach the device to a tractor or similar vehicles. These brackets allow for installation on almost all vehicles in this category.

[0014] According to one embodiment, one or more sliding shoes are provided on the support frame. This ensures the device's ability to adapt to the ground.

[0015] Preferably, the device features a swivel joint, a sliding shoe conveying mechanism, and a floating position for the hydraulic cylinder to ensure optimal ground contour following and crop pickup. This combination allows the crop to be picked up cleanly and with minimal residue.

[0016] It should be noted that the device incorporates one or more suction-pressure blowers. For example, several small suction-pressure blowers can be installed to save space.

[0017] For example, one or more conveying devices may be provided on the device.

[0018] A variety of narrower conveying devices results in better ground contour following.

[0019] It should also be mentioned that the device includes one or more interior spaces.

[0020] This can be achieved, for example, by partitions when multiple suction-pressure blowers are installed.

[0021] A hydraulic motor, for example, can be used to drive the conveying device and the suction-pressure blower. This allows, for instance, a power supply from a tractor or towing vehicle.

[0022] The mechanical drive power of the tractor can be used, for example, to power the conveying device and the suction-pressure blower. This can be achieved, for instance, via drive shafts, commonly known as power take-off shafts.

[0023] An electric motor can be used to drive the conveying device and the suction-pressure blower. This allows, for example, an electrical supply from a towing vehicle.

[0024] According to one embodiment, gauge wheels are provided instead of the sliding shoe support frame and the sliding shoe conveyor device. These gauge wheels are then mounted, for example, so that they can rotate laterally.

[0025] According to another design, an intermediate piece is attached to the support frame, which is fitted with, for example, a compression spring, thus compensating for shocks and vibrations caused by the operation of the device for moving harvested crops. This has a positive effect on the device's longevity.

[0026] One idea of ​​the invention can be seen as the construction of a device that, with low-maintenance and low-cost technology, ensures the gentle and clean handling of harvested crops, thus making the full quality of the harvested crop available to, for example, farm animals that eat the harvested crops.

[0027] The individual features can of course also be combined with each other, which can sometimes result in advantageous effects that go beyond the sum of the individual effects.

[0028] Further features, details and advantages of the invention will become apparent from the wording of the claims and from the following description of exemplary embodiments with reference to the drawings. The drawings show: Fig. 1: a side or profile view of the device Fig. 2: a three-dimensional drawing of an exemplary embodiment of the device Fig. 3: Example of harvest crop separation Fig. 1: Description of the device

[0029] Various components of the device can be seen here. The crop is described as 1, which is then taken into the interior 10 by the conveying device 6.

[0030] As a conveying device 6, a pick-up is described here, for example, based on the prior art. The crop is picked up by rotating tines. The roller hold-down 5 is used in many applications of the pick-up in combination with the pick-up to ensure smooth crop pickup. The pick-up is rotatably mounted on the pivot 20 and can adapt to the ground surface 2 by means of the floating position of the hydraulic cylinder 13 and the sliding shoe of the conveying device 12, thus cleanly picking up the crop 1. The housing 8 is shown here as an example in this embodiment and can certainly have a different shape. The interior 10, in which the crop is transported, is largely enclosed so that the compressed air and suction air can act and operate optimally. The support frame 9 extends, for example, from the underside of the housing 8 as well as over its rear.Mounting brackets for tractors or towing vehicles, or attachments for large working widths, can be mounted here. The sliding shoe support frame 3 is connected to the support frame by means of an intermediate piece, thus allowing the device to adapt to the terrain. Fig. 2: Fig. 2 describes the function and relationship of the device.

[0031] The crop 1 lies on a ground surface 2, for example, on a meadow. This crop is then picked up by the conveying device 6 and transported into the interior 10. This conveying device is, for example, a pick-up. The pick-up has rotating tines that ultimately pick up the crop 1.

[0032] Once the harvested crop 1 has arrived in the interior 10, it is moved in an airflow to the [unclear text] by means of incoming compressed air from the compressed air duct 7 and suction air from the suction air inlet 16. Fig. 3 described harvest material separation device promoted. Fig. 3: Fig. 3 shows an embodiment of the crop separation.

[0033] The interior 10 and the suction-pressure blower 14 are primarily visible. These are connected by a crop separation device.

[0034] The suction-pressure blower 14 draws the airflow, in which crop 1 and air are located, through which it is in Fig. The air enters the intake 16 described in section 2 and thus reaches the point where the air and the crop 1 must be separated. This occurs at the crop separation device 17. The crop separation device 17 therefore has the function of allowing air to flow through it but preventing the crop from passing through. This can be achieved, for example, by a sloping perforated plate. The crop 1 falls onto the ground surface 2, and the majority of the air continues to flow through the suction-pressure blower and is returned as compressed air via the [unclear - possibly referring to a specific component or device]. Fig.The compressed air described in section 2 is fed into the interior 10, and the cycle begins again. Since this is a closed loop and these suction-pressure blowers meet the required specifications, it is in no way a negative aspect that small particles of harvested crop 1 are transported further in the cycle.
