Definitions

  • the invention relates to a pick-up attachment for a preferably self-propelled forage harvester, comprising a pick-up rotor with pick-up tools for picking up crops from the ground.
  • Forage harvesters are agricultural machines used for harvesting and collecting crops, cutting crops into short parallel lengths, and conveying the chopped crops into containers or separate vehicles.
  • Typical crops are grasses, legumes, mixtures and/or crops in row crops, such as maize or millet.
  • the chopped material can either be stored by silage or drying, or it can be fed directly to the livestock.
  • the forage harvester can harvest the crop directly by cutting it across the full width or from single or multiple rows or by collecting it from the windrow.
  • Forage harvesters can be tractor-mounted, tractor-towed, or self-propelled.
  • a header is a device, usually detachable, for receiving the crop into the forage harvester.
  • a pick-up attachment as a harvesting attachment is specifically a device for receiving previously cut crops. The harvested crop can be deposited in rows or windrows.
  • Known pick-up attachments for self-propelled forage harvesters include a rigid roller-type pickup rotor with pickup tools for picking up crop from the ground.
  • the rigid receiving rotor is here fixed, that is to say likewise rigid, or connected in a swinging manner to the machine frame of the pick-up attachment or attached to it.
  • Such receiving rotors are guided over the ground by guide elements arranged laterally next to the receiving rotor, in particular feeler wheels or feeler skids.
  • the roller-like pickup rotor describes a rigid straight line that extends between the two guide elements.
  • the pick-up rotors can have a controlled or an uncontrolled tine guide.
  • pick-up attachments with a rigid or a foldable machine frame, which has a pickup rotor arranged thereon are known.
  • Self-propelled forage harvesters have now achieved an engine output of over 1000 hp.
  • the throughput of the forage harvester has increased in parallel to the engine output.
  • the harvesting capacity is also an important factor for high forage quality in grass silage. After mowing, the meadows and fields must be cleared within a short time window, e.g. B. to be able to ensile the green fodder with optimal dry matter content.
  • the pick-up attachment In order to take account of the above, the pick-up attachment must be run higher than usual, with the pick-up tools, especially rake tines, no longer reaching up to the turf, which leads to crop losses because crop material is not collected in depressions in the terrain, or the pick-up attachment must be lower than are usually guided, with the pick-up tools, in particular the rake tines, aggressively combing through the ground or the turf, which leads to massive forage contamination and thus a reduction in forage quality, damage to the turf and increased machine wear on both the pick-up attachment and the forage harvester , since a lot of dirt, especially sand and soil, is picked up.
  • the pick-up rotor On the pick-up attachment itself, the pick-up rotor has to rotate faster at higher forward speeds in order to be able to reliably pick up the crop mat. In turn, increasing the speed leads to increased wear on the tines and scrapers, especially in the case of controlled tine systems. This in turn increases the risk of broken tines and higher operating costs.
  • the object of the invention is to provide an improved pick-up attachment which, in particular, overcomes the aforementioned disadvantages and the increasing throughput of forage harvesters operated without having to accept losses in operating costs and forage quality.
  • the pick-up attachment according to the invention for a preferably self-propelled forage harvester comprises a pick-up rotor with pick-up tools for picking up crops from the ground and is characterized in that the pick-up rotor is composed of a plurality of segments which are at least partially articulated to one another in order to adapt to the contours of the ground.
  • the pickup rotor of the pick-up attachment is composed of several segments that are at least partially connected to one another in an articulated manner, it is achieved that the pickup rotor is flexible, as a result of which it can adapt to the ground contour. It is thus possible for the pickup rotor to at least partially adapt to the contour of the depression when driving over a depression or, conversely, when driving over an elevation, to the contour of the elevation.
  • the receiving rotor sags downwards at the relevant point or, conversely, arches upwards at the relevant point.
  • the pickup rotor of the pick-up attachment is designed to be flexible, it is possible to increase the working width of the pick-up attachment to increase the pickup capacity.
  • Pick-up attachments designed in this way are also suitable for larger working widths in hilly terrain. Because the pick-up rotor adapts to the contour of the terrain, the pick-up rotor and thus the pick-up tools, in particular rake tines, can be guided at an optimum distance from the turf for picking up the harvested crop. This means that there are no harvest losses, since the harvested material is reliably collected even in depressions in the terrain. In addition, it prevents the pick-up tools, especially rake tines, from combing aggressively through the turf.
  • Flexible intake rotors are known per se in the so-called belt rakes from RT Engineering GmbH, in which the flexible intake rotor is rigidly connected to a transverse conveyor belt.
  • the picked-up material is conveyed onto a conveyor belt, which moves at right angles to the direction of travel.
  • the conveyor belt then deposits the swath on the desired side.
  • the swath can then be picked up and processed further, for example with a forage harvester that has the pick-up attachment according to the invention.
  • the unit consisting of the intake rotor and cross conveyor belt is connected to the machine frame in a pendulum manner in the aforementioned belt rake.
  • the pick-up rotor has uncontrolled and degressive tines.
  • a cross conveyor belt would be unsuitable for the pick-up attachments according to the invention for self-propelled forage harvesters.
  • the pick-up attachment according to the invention preferably has a transverse auger behind the pickup rotor, ie pointing towards the forage harvester, in order to bring together the crop picked up via the pickup rotor and transfer it to the forage harvester.
  • the pick-up rotor is flexible over the entire working width. That is articulated by numerous connected segments ensured.
  • the flexibility of the pick-up rotor across the entire working width enables optimum harvested crop pick-up, even if the pick-up attachment is simultaneously guided over at least one depression and/or at least one elevation of the hilly terrain. This ensures a high forage quality overall with low harvest losses
  • a plurality of guide elements distributed over the working width of the pick-up attachment are provided, which guide the pick-up rotor and/or guide it to the ground.
  • not providing such guide elements arranged laterally next to the receiving rotor is advantageous even for smaller working widths of up to 3 m.
  • the guide elements are arranged below and/or directly behind the pickup rotor and/or within its effective working width. This allows the pick-up rotor to adapt to the ground contours of the terrain over its entire working width.
  • the guide elements are at least partially designed as sliding plates.
  • the flexibility of the pick-up rotor together with the guide elements designed as sliding plates also supports the height control of the forage harvester. This ensures that there is always an optimal distance between the pick-up tools, in particular the tines, the exception rotor and the turf.
  • the machine frame of the pick-up attachment can be folded up to a specified transport width and unfolded to a specified working width.
  • the legally permissible transport widths specified in different countries can be observed.
  • much larger working widths can be achieved than with previous pick-up attachments for forage harvesters.
  • the broadening or increase in the working width of the pick-up attachment serves the increasing throughput of the forage harvester without having to accept losses in operating costs and forage quality.
  • the combination of a larger working width and a flexible intake rotor supports higher forward speeds and the increased throughput of modern forage harvesters.
  • the machine frame of the pick-up attachment can advantageously have a two-part or multi-part folding mechanism.
  • the flexible receiving rotor is separated accordingly when folding at the folding couplings provided for this purpose.
  • the previously separate parts of the flexible receiving rotor are reunited and connected via the folding couplings in such a way that the flexible receiving rotor can be driven via only one central drive.
  • the pick-up attachment has a transport width that corresponds to the working width, which is 3 m to a maximum of 4.50 m.
  • the pick-up attachment has a transport width when folded up that is the maximum legally permissible, preferably 3 m, and when unfolded it has a working width that is greater than the transport width, preferably 6 m.
  • the pick-up rotor is designed as an uncontrolled pick-up rotor with preferably degressively arranged pick-up tools, preferably degressively arranged tines.
  • the tines extend along a circular path and can rotate around a fixed axis of rotation.
  • the tines would be able to tilt and/or move in and out in addition to the orbital movement, with the said orbital path often deviating from the circular shape.
  • the tines are spring tines that have the shape of a torsion spring with long legs as a distinguishing feature.
  • the spring tines can be designed as double torsion springs.
  • Degressive means that the legs of the tines or spring tines are angled or bent counter to the direction of rotation.
  • the speed or peripheral speed of the receiving rotor can also be significantly increased when the feed rate is increased massively.
  • the degressively arranged tines ensure that little dirt gets into the forage, thereby increasing the quality of the forage. Furthermore, the degressive tines are not prone to picking up stones and other debris compared to the aggressive tines in steered pickup rotors. This reduces downtime and minimizes machine wear. In other words, the uncontrolled tine connection and the resulting degressive alignment of the tines have a positive effect on the quality of work at higher feed speeds, since this allows higher speeds of the pick-up rotor with less wear and offers greater protection against picking up foreign bodies and dirt.
  • the flexible receiving rotor is firmly or rigidly connected to the machine frame.
  • the adaptation to the contours of the floor then takes place virtually only via the flexibly designed receiving rotor.
  • the flexible pickup rotor or the machine frame of the pick-up attachment can be combined or combined with a transverse pendulum frame, which is arranged on the attachment side, i.e. on the pick-up attachment, or on the chopper side, i.e. on the forage harvester .
  • the flexible receiving rotor is connected to the machine frame with an additional oscillating movement relative to it.
  • the flexible pickup rotor is connected to the machine frame of the pick-up attachment in a pendulum or swinging manner.
  • the additional oscillating relative movement can allow a type of vertical movement between the pickup rotor and the machine frame of the pick-up attachment, so that the ground adaptation of the pick-up attachment is significantly improved.
  • This combination can be particularly advantageous in very hilly terrain and at high feed rates, as the known chopper-side guidance systems for pick-up attachments, which are designed as ground pressure controls, reach their limits at high feed rates.
  • the oscillating relative movement adapts the pickup rotor directly and reactively to the bottom docking.
  • the guide on the chopper side only has to hold the pick-up attachment in a kind of neutral position in relation to the pickup rotor.
  • the flexibility of the receiving rotor is supplemented by the oscillating or oscillating up and down movement of the connection. This leads to even better ground tracking of the pick-up attachment, especially in very hilly or alpine areas. Especially at high feed speeds, the oscillating relative movement adapts the pick-up rotor directly and reactively to the bottom docking.
  • At least one swinging arm is preferably provided, which is in operative connection with the flexible receiving rotor or with a guide element connected to the receiving rotor.
  • the swing arm is connected to the pickup rotor of the pick-up attachment at one end pointing towards the pickup rotor, i.e. the end pointing forwards, and to the machine frame of the pickup attachment at the other end pointing towards the forage harvester, i.e. the end pointing backwards.
  • the pickup rotor can advantageously be relieved, for example via the swing arm, by means of relief elements, such as tension or compression springs.
