Definitions

  • the invention relates to a corn harvesting device according to the preamble of claim 1.
  • Such corn harvesting devices with a cutting device separating the corn stalks are already known and used in various designs.
  • complete vehicles which are only suitable for the harvest of plants, such as corn, and on the other hand, stems, which can be connected to an agricultural vehicle.
  • DE 103 50 302 B4 describes a corn harvesting device with a cutting device separating the corn stalks down to stubble height, wherein the cutting device is arranged downstream of at least one stubble separation device separating the stubble into the region near the ground.
  • the underside of the cutting device has an additional, rotating cutting blade.
  • the disadvantage here has been found that the cutting blades are very susceptible to interference and often subject to damage.
  • DE 10 2010 012 686 A1 proposes an additional device which has a erecting tool which has a rotatably mounted rotary body with a number of prongs.
  • the mechanical and the processing costs for the erection of the maize stubble here is considerable and therefore not economical.
  • Fusarium is a genus of the ascomycete fungi. These preferentially grow in plant tissue. The disease caused by Fusaria is called fusariosis. Often it affects the root or stem area of the corn plant. The attachment of the Fusaria to their host plant is often very close. Fusariums produce toxic metabolic products (mycotoxins), so that contamination in the percentage range (for example for feed grain) is already fatal for some animals.
  • the Fusaria are still one of the great unresolved problems of agriculture today and are one of the world's most important harmful fungi in cereals and maize.
  • the released poisons can spoil whole harvests.
  • Amazing is the great variety of Fusarium.
  • the invention has for its object to provide a corn harvesting device that allows simple means, with economically justifiable effort and in the most environmentally friendly manner, a very effective control of the corn borer.
  • a corn harvesting device with a cutting device separating the stalks of corn up to stubble height has been further developed according to the invention such that the cutting device is arranged downstream of at least one pressing element depressing the stubble.
  • the decisive advantage is achieved that the stubble left on the field after harvesting the corn plants kinked and flat on pressed the ground. This causes a complete death of the stubble up to the root of the plant and thus deprives the corn borer any death.
  • An energy and labor intensive plowing of the field can thus be completely eliminated, which ultimately also makes a contribution to environmental protection.
  • the pressure element is therefore not only very effective in its application. It also represents a structurally simple design, for which no additional drives or cutting blades are required.
  • the invention has also provided a cost-effective and less susceptible to interference solution, which even allows retrofitting already existing corn harvesting devices without any problems.
  • a further advantage of the invention is the fact that at the same time as the harvest of the maize plants, the destruction of the population of the European corn borer in a natural, environmentally friendly manner is possible.
  • a first embodiment of the invention is to be seen in that the corn harvesting device is designed as a whole as a stem of a vehicle. This solution has the advantage of having to use the stem only in case of need and otherwise to use the agricultural vehicle for other purposes.
  • a further proposal according to the invention is to releasably connect the corn harvesting device to the vehicle.
  • the Corn harvesting device can be completely disassembled from the vehicle when it is no longer needed.
  • the main advantage of a detachable embodiment of the corn harvesting device is the more flexible handling of the agricultural vehicle and, moreover, because of the saving of fuels has an energy saving potential, which in turn reduces the operating costs.
  • the entire corn harvesting device can be detachably connected to the agricultural vehicle, according to a further aspect of the invention, it is also possible to releasably connect the pressing element to the corn harvesting device.
  • the detachable mounting of the pressure element allows its replacement, simplified cleaning and possibly a repair of individual components or the entire pressure element with little effort.
  • the pressure element has a profiled surface on its underside facing the bottom.
  • the profiled surface is understood any form of surveys and introduced into the pressure element structures, which means in a broader sense, an uneven surface and causes the stubble of maize plants are partially or slightly kinked into the soil or broken off. The profiled surface thus significantly improves the quality of the post-processing of the harvested corn plants.
  • a “profiled surface” can also be understood to mean a reinforced edge in the edge area, ie in the immediate area of contact with the floor
  • a rake-type structure of the end section of the pressure element also has the advantage that the surface of the floor is smoothed after the stubble is bent and in this way freshened for a new introduction Seed is prepared.
  • the pressure element has sawtooth-like or cutting-like elevations on its bottom side facing the bottom.
  • Such elevations can be used to not only press the stubble by means of the pressure element to the ground, or to press them into the ground. Rather, these Erbungen simultaneously serve to achieve additional comminution or additional cutting of stubble, which significantly improves the overall effectiveness of the pressure element.
  • the maize harvesting device should have at least one pressure element whose width corresponds to a corn line width. So for example, it is conceivable that a corn harvesting device has a plurality of pressing elements next to each other according to the arrangement of the rows of corn plants.
  • the width of the pressure element corresponds to the width of the entire corn harvesting device. In this case, therefore, only one pressure element is used, which extends over the entire width of the corn harvesting device.
  • the decision for one or the other variant is also largely determined by the ease of installation of such a pressure element.
  • the weight plays a crucial role.
  • a further proposal according to the invention is to provide at least one pressure device pressing the pressure element against the ground between the corn harvesting device and the pressure element.
  • the additional printing device an increased contact pressure of the pressure element is achieved against the ground.
  • a printing device various technical devices are suitable, only by way of example a coil spring, a leaf spring, a rubber spring, a gas spring or a hydraulic device are mentioned.
  • the pressure devices generate on the one hand the already mentioned contact pressure of the pressure element against the ground and on the other hand permit evasive movements of the pressure element, if this is performed, for example, on uneven floors.
  • the invention will be explained in more detail with reference to the accompanying drawings. The embodiments shown are not limiting to the variants shown, but merely serve to explain a principle of the invention.
  • FIG. 1 shows a first embodiment variant of a corn harvesting device with a pressure element
  • Figure 3 a detail of the view in the direction of arrow II of Figure 1 to a further variant of a pressure element
  • Figure 4 a second embodiment of a corn harvesting device with a pressure element.
  • the corn harvesting device 1 shown in FIG. 1 is designed as a stem mounted detachably on an agricultural vehicle 6.
  • the corn harvesting device 1 is designed finger-like for receiving a plurality of maize rows planted parallel to one another in their front region.
  • the maize stalks 2 are picked up in this finger-like front region of the corn harvesting device 1 and separated in the following, only schematically illustrated cutting device 3 up to the height of the stubble 4.
  • the inventive feature of the corn harvesting device shown in Figure 1 is that the cutting device 3 is a pressure element 5 downstream.
  • This pressure element 5 forms a detachable and connectable to the corn harvesting device 1 substructure, which has a curved, contrary to the direction of travel of the vehicle 6 the ground 7 approaching geometry.
  • the pressure element 5 is in this case designed as a equipped with a profiled underside 8, stable sheet.
  • FIG. 2 permits a view in the direction of the arrow II in FIG. 1. It can be seen that the underside 8 of the pressure element 5 has a large number of elevations 10 extending in the form of a fishbone. This special embodiment of the profiled underside 8 of the pressure element 5 is of course not to be understood as limiting. Likewise, any other form of profiled surface can be used. It is only important that an improved kinking of the stubble 4 of the corn stalks 2 takes place through the elevations 10.
  • FIG. 3 shows a view in the direction of the arrow II from FIG. 1 of another possible variant of a pressure element 5.
  • This pressure element 5 has a multiplicity of sawtooth-like elevations 10 on its underside 8 facing the bottom 7, which next to the already described pressing of the stubble 4 additionally cause comminution or cutting of the stubble 4. In this way, the effectiveness of the destruction of the corn borer and also of the fusarium can be significantly improved.
  • FIG. 4 shows a further embodiment variant of a corn harvesting device 1 according to the invention.
  • the design of the otherwise identical corn harvesting device 1 differs from that shown in FIG. 1 in that between the underside of the corn harvesting device 1 and the end section of the pressure element 5
  • Printing device 9 is arranged, which in the present case is a gas spring.
  • This printing device 9 causes in particular that the end portion of the low elasticity having pressure element 5 is pressed with increased force against the bottom 7 and at the same time evasive movements when driving over bumps are possible. As a result, premature wear of the pressure element 5 is prevented.
