Definitions

  • the present invention relates to a device for harvesting stalky stalks comprising a catchment area, a conveying device, a picking device and a stalk cutting device arranged in a plane below the picking device, which rotate at least one in a horizontal or at least approximately horizontal plane having circumferential knife.
  • a generic device is known from the document DE 203 03 819 U1. After a stalk of Halmguts such as a corn plant in the harvesting device run in this device, torn down by picking rollers and the Fruchtstand, such as a corncob of a corn plant, has been separated from the picking device by the corn stalk thereby picking plates, the remaining maize stalks further down.
  • a torn down stalk can thereby be cut by fixed or rotating knives, which are arranged in the region of the picking rollers.
  • the stem is cut off from the root system remaining in the ground near the ground by a separate cutting device with at least one knife rotating in an approximately horizontal plane.
  • the rotating knife can cut stalk pieces that have been transported downwards from the stalkrolls into shorter stalk pieces, which are then dropped onto the field. There, the stalk pieces can then rot.
  • the corncobs separated from the stalk are fed by the conveying device to a threshing device.
  • the cut surfaces of the stem pieces are cut smoothly by the chopping knife rotating approximately in the horizontal plane, it takes some time before moisture and bacteria penetrate from the outside into the interior of a stem piece. penetrate and accelerate the rotting process. This delays the decomposition process. This is especially true for the stubble, which still remain standing upright in the field. Insects, such as the corn borer, whose caterpillars later cause considerable damage in maize stocks, often settle in the stubble which is still standing upright. To prevent this, the stubble should be damaged more.
  • baffle element is formed on the rotating rotating blade, which rises above the thickness of the knife blade blade.
  • the knife blade is the part of the knife that carries the knife blade.
  • the knife blade has a sharpened cutting edge, which cuts the material of a plant at the interface during a cut.
  • the knife blade is normally designed to be flat in order to be able to pull the knife through the cut material with as little force as possible.
  • the knife now additionally has one or more baffle elements which project beyond the thickness of the knife blade blade and impact on the stubble body during a rotational movement of the knife and a cut of a rod.
  • the outer layers of the stem axis are ruptured, the underlying strengthening tissue of the stem is defibered and spliced along the longitudinal axis of the stopper.
  • the smooth surface is destroyed.
  • the surface is significantly increased by the destruction, which bacteria and moisture can easily penetrate into the stubble.
  • the stubble rots faster.
  • the destructive effect on the stubble can be increased if a plurality of impact elements are formed on a knife.
  • baffles The energy required to allow the knife to rotate with the baffle or baffles is indeed increased by the baffles compared to a conventional knife. Since the baffle or baffles are attached only to individual points of a knife, the additional energy expenditure, however, remains relatively low. This is especially true because the contour of the knife remains unchanged energetically favorable apart from the one or more impact elements.
  • the degree of destruction of the stubble that can be achieved by the impact elements is so high that, depending on the crop, it is possible to dispense with mulching post-processing.
  • the Stoppelzerone is possible before a stubble rolled over by the wheels of a harvester and an undamaged stubble is pressed into the ground. Such a stubble would not be attainable for stubble cultivation and could nevertheless damage subsequent growth by insect infestation and fusaria.
  • the knife is at a rotational speed of at least 1, 500 U / min. driven all around. At such rotational speed of a rotating in a picking attachment blade results in a very high impact velocity of the impact element on a stubble. The thereby acting on the stubble energy acts beyond the direct contact zone of the impact element with the stubble and also damaged adjacent areas of a stopper that does not directly reach the baffle itself.
  • the harvesting device no longer needs to be guided so close to the ground that the stubble is cut to a maximum length of 5 cm, considered critical for European corn borers. Rather, the harvesting device can be guided over the ground at a greater distance, reducing the risk of damage from foreign body contact. With such a blade speed, a single stubble is hit several times by a baffle element, which additionally increases its degree of destruction.
  • the baffle element has a cylindrical shape with a rounded tip.
  • the cylindrical shape is ideal for absorbing and distributing the impact energy into the material of the impact element without deforming or destroying the impact element itself.
  • the use-related material removal on the side of the impact element pointing in the direction of rotation is distributed uniformly over the surface, resulting in a long service life of the impact elements.
  • the impact element is massively made of a metallic material whose outer layer is additionally hardened.
  • a metallic material such as steel has a high resistance ability, resulting in long service life of the impact element. Due to the massive design, the service life increases additionally.
  • the hardening of the outer layer reduces the material removal by the constant contact with the stubble.
  • the baffle elements are arranged only on the knife side facing the ground. Since, in particular, the stubble is to be damaged, in the case of an arrangement of the impact elements, the additional expenditure of energy remains limited only on the side of the blade facing the ground.
  • the at least one baffle element is arranged in the middle region of the blade width. This arrangement is advantageous because the knife has its greatest strength in this area.
  • the at least one baffle element is screwed with a countersunk screw with the knife.
  • the countersunk screw can be countersunk in the material of the knife so that it does not project beyond the profile of the knife and can be removed by material contact.
  • the screw remains functional. If the first blade side of the blade is worn, the baffle can be screwed without much effort on the other side of the knife blade, so even with an inverted knife with an unchanged direction of rotation of the knife with the second blade side in the direction of rotation on the underside of the knife is arranged.
  • At least two picking rollers arranged along the picking gap are arranged beneath the picking plates, the enveloping circles of which overlap at least in regions.
  • the described impact elements produce a very efficient comminution system which reliably grips the corn stalks, conveys them downwards and not only minces and shreds the cut stalk parts, but also the upper ends of the stubble still standing on the field ,
  • stationary or rotating blades reaching into the enveloping circles of the picking rollers are arranged at intervals along the length of the picking gap.
  • the fixed or rotating knives cause a very efficient shredding of the plant remains, which are pulled down through the picking gap.
  • FIG. 1 is a sectional view of a part of a harvesting device
  • 2 shows a view of the assembly shown in Fig. 1 from the front
  • FIG. 3 shows a view of the underside of the assembly shown in FIG. 2 with the baffle elements on the knives.
  • a section of a device 2 for harvesting stalky stalks is shown.
  • the device has a conveying device 4, which in the exemplary embodiment consists of two opposing conveyor chains, which have on their outer side a number of carriers, with which cornsticks separated from the corn stalk 14 can be carried away.
  • the corncobs are separated from the corn stalk 14 with a picking device, which in the exemplary embodiment consists of two picking plates 6, which delimit a picking gap 8 with their mutually facing sides.
  • the corn stalk 14 slides through the length of the picking gap 8, while the picking rollers 10 arranged below the picking gap 8 grasp the corn stalk 14 and tear it downwards.
  • a cutter disk 12 additionally cooperates with the picking rollers 10 in order to comminute the corn stalks 14 captured by the picking rollers 10.
  • a rotor shaft 16 Up to the area below the picking rollers 10, a rotor shaft 16, at the lower end in the exemplary embodiment, two blades 18 are attached.
  • the two blades 18 rotate in a horizontal plane. With a rotating movement of the blades 18, these cut off the corn stalks from the stubble 20 remaining in the ground.
  • the knives 18 may also still rotate Parts of the corn stalk fall down from the picking rollers 10 and the blade disc 12 fall.
  • the two blades 18 are each equipped with three additional impact elements 22.
  • the baffle elements 22 are located on the underside of the blades 22 facing the bottom. The baffle elements 22 project beyond the cross-sectional area of the two blades 18. They thus reach lower to the bottom than the blade of the two blades 8.
  • Fig. 1 the stubble 20 is still shown in intact form. However, if the stubble 20 has been hit several times by the baffle elements 22, the stubble 20 has lost its cylindrical shape in its upper region. He is then severely damaged and splits.
  • Fig. 2 is a view of the assembly shown in Fig. 1 is shown from the front.
  • the impact element 22 has a cylindrical shape with a rounded tip 24.
  • the baffle 22 is made of a metallic material and is solid.
  • baffles 22 are arranged in the central region of the width of the blade 26.
