Definitions

  • the invention relates to a forage harvester with a receiving device for the material to be chopped and an ejector tube connected to a chopper and / or conveying device with an ejector opening, and a secondary comminution device.
  • the task of the re-shredding device is to subsequently shred components of the chopped material that have undergone the chopping process without the desired shredding prior to being ejected. For example, in the case of the silage maize harvest, whole chopped corn should no longer be present in the chopped material ejected.
  • a re-crushing device in particular for corn kernels, is known, which is attached to the retaining wall in the chopper housing, the plate-shaped friction base interacting with strip-shaped counter tools.
  • a number of similar solutions with non-driven shredding tools also show how the device according to DE-U 77 23 116 has only a small comminution effect, while constructions with driven comminution tools, such as squeeze rollers, allow good grain comminution, but require a lot of construction, have the risk of clogging and have a high energy requirement, as well as squeezing the entire chopped material and thus destroying the forage structure of the stalks and lies. If the chopper is not self-propelled, it can only be operated in conjunction with a very powerful tractor due to the high energy requirement.
  • a chopper is known, the shredding arrangement of which is located in a bulge in the chopper housing, into which only the maize kernels enter after deliberate separation after the chopping process. Since the chopped material is strongly mixed with one another, especially at high throughput, stem parts enter the secondary shredding device, where their structure is destroyed by the squeeze roller and their residues can clog the squeeze roller in such a way that the grains are no longer squeezed because of the elasticity of these residues.
  • the invention is based on the object of designing a forage harvester of the type mentioned at the outset in such a way that it has a structurally simple and clog-proof secondary shredding device which does not adversely affect the energy consumption of the forage harvester and enables optimal grain size reduction while largely maintaining the cut structure of the other chopped material.
  • the secondary comminution device consists of more than one group of profiles arranged in the impact area of the material which is accelerated or to be accelerated by the chopping and / or conveying device with spaces in such a way that the spaces of each group on the end approximately in the conveying direction end of each group and the profiles of each group are offset from the profiles of the following group in such a way that the mouths of the gaps each face a profile of the following group.
  • the crushing e.g. Corn kernels occur when the profiles and the grains collide, without the need for a counter tool assigned to the profiles, which would cause an additional energy requirement to carry out a crushing or rubbing process.
  • a self-cleaning effect is achieved by the opening of the gaps in the conveying direction, because no residues can accumulate and press firmly into the gaps.
  • stems and the like are not held or crushed in the area of the secondary shredding device. Grains, which may pass through a group of the profiles without being crushed, meet one of the profiles of the following group due to the staggered arrangement of the spaces and the profiles, and are crushed by this, so that an optimal degree of crushing is achieved.
  • the profiles preferably rise like strips in a base area.
  • a particularly advantageous embodiment consists in the fact that the following group is lowered relative to the group arranged in front of it to form a step running transversely to the conveying direction, whereby according to a further expedient embodiment the individual groups are arranged to rise in the conveying direction.
  • the apexes of the profiles are preferably narrower than the base thereof, it being possible for the apexes to also have a cutting shape. Flattening or rounding the bottom of the space should prevent residues from wedging at the bottom of the space.
  • the intermediate space can widen in the conveying direction in such a way that the profiles diverge like rays.
  • At least the profiles of a group are expediently arranged on a common base plate.
  • the successive groups are preferably combined on a common base plate to form a secondary comminution unit.
  • the profiles are attached to the circumference of a roller which is rotatably mounted about a horizontal axis arranged transversely to the conveying direction.
  • the axis of the roller is preferably arranged approximately in the region of the outer wall of the ejection tube in relation to the radius of curvature.
  • the roller can be rotated loosely or driven in such a way that the roller surface facing the delivery cross section of the ejection tube is moved against the delivery direction.
  • the secondary comminution device is arranged on the outer wall of the discharge tube in relation to the radius of curvature in the section following the start of the deflection of the conveying direction.
  • the secondary comminution device is preferably arranged in the region of the discharge opening, because this results in a particularly long path of the chopped material from the chopper device to the secondary comminution device and thus optimal separation of the chopped material. In this way e.g.
  • the grains which are heavier than the stalks and Lieschen, under the effect of centrifugal force in the curved discharge tube and hit the secondary shredding device, while the lighter, more elastic parts of the plant are mainly conveyed in the radially inner area.
  • the grains hit unhindered and undamped from elastic plant parts on the profiles of the post-shredding device, tear and splinter, while the light lining parts are retained in their structure.
  • the secondary comminution device can be pivotable about a horizontal axis running transversely to the conveying direction, whereby on the one hand the impact angle is adjustable and on the other hand the secondary comminution device can be pivoted into an ineffective position if its effect such as grass or green corn, is not desired or required.
  • the post-shredding device can be arranged so that it can be pushed in and pushed out through an opening in the outer wall of the discharge tube.
  • the secondary comminution device can be arranged on the deflection flap and can be adjustable with it.
  • the downstream section of the discharge pipe can be arranged so as to be adjustable about a hinge joint with a horizontal axis attached to the outer wall of the discharge pipe. This can also change the throw range.
  • FIG. 1 shows a schematic side view of a forage harvester designed according to the invention, the downstream section of which is shown in two different positions
  • FIG. 2 shows a section through part of the discharge pipe with different variants of the positioning of the secondary shredding device
  • FIG. 3 shows an end view of part of a secondary shredding device partially broken off 4 shows a section along the line IV-IV in FIG. 3
  • FIG. 5 shows a section similar to FIG. 4 through a welded embodiment of a post-shredding device and
  • Fig. 6 shows a curved embodiment of a
  • a field chopper 10 for example designed as a disc wheel chopper, is provided with an attachment 12, here a maize header, and essentially consists of a chopper housing 14 with cutting and throwing organs arranged around it and the subsequent ejection tube 16.
  • the ejection tube 16 has a curved course and is provided with an ejection opening 18 at the end.
  • an adjustable ejector flap designated overall by 20, which is connected to the ejector tube 16 so as to be adjustable about a horizontal axis 22 running transversely to the conveying direction and in turn consists of two sections 20a which are adjustable relative to one another about an axis 24 parallel to the axis 22 and 20b.
  • the ejection tube 16 is divided into two sections 16a and 16b, which are connected by a horizontal axis 26 which runs transversely to the conveying direction and which is arranged in the outer wall 28 with respect to the radius of curvature of the ejection tube 16. This allows the throwing distance to be changed and the separation of the chopped material to be influenced by the discharge tube during the flight.
  • a schematically illustrated adjusting spindle 30 is provided, which is one is supported on section 16a via a nut 31 and on the other hand on section 16b.
  • At least one secondary comminution device is arranged, on which crushing forces are obtained by the impact from the kinetic energy, which are particularly effective for comminuting the grains still in the chopped material.
  • FIG. 3 An embodiment of a secondary comminution device 32 is shown in FIG. 3, the view in the conveying direction being directed against the device 32.
  • the secondary comminution device 32 consists of spaced-apart, rib-like profiles 34, which run in the conveying direction and rise somewhat in the conveying direction, so that their apex surfaces 36 project into the trajectory of the chopped material.
  • the profilings 34 can, for example, also be designed in the form of a knife or a knife.
  • the apex surfaces 36 can also be provided with a toothing, for example in the shape of a saw tooth, or the knife-like profiles can have a serrated edge. It is important to have a sufficient distance between the profiles, the space 38 between the individual profiles 34 having a flattened or rounded sole 40 so that no residues can wedge in this space.
  • a first group 42a of profiles 34 is followed by another Groups, for example two further groups 42b and 42c, the groups being offset from one another in such a way that a profile 34 of a subsequent group is aligned with an intermediate space of the preceding group. This also comminutes the parts which do not meet a profile 34 in the first group 42a, but rather an intermediate space 38.
  • a further possibility of the arrangement consists in the fact that within the individual groups the spacing of the profiles from one another increases in the conveying direction, so that overall a radial arrangement of the profiles 34 is created. As a result, in particular the self-cleaning effect is promoted under the influence of the chopped material that passes through the spaces 38.
  • the individual groups 42a to 42c are arranged so that the profiles 34 each
  • the individual groups 42a to 42c can be manufactured separately and then welded together in the desired number to form a secondary comminution device 32, as shown in FIG. 4.
  • secondary shredding devices 32 can also be manufactured in one piece with the desired number of groups, Eg cast or milled, as shown in FIG. 5.
  • the re-shredding device 32 itself can also be curved in the conveying direction, as shown in FIG. 6.
  • a still further possibility is to combine the individual groups 42a to 42c interchangeably on a common base plate to form a secondary shredding device, so that the most favorable number of profiling groups or the most favorable form of profiling can be selected depending on the type of chopped material, positioning of the secondary shredding device or similar creteria.
  • the plate-shaped secondary comminution device 32 is fixedly connected to the outer wall 28 of the ejection tube 16 or the corresponding wall of the sections 20a or 20b of the ejection flap 20. This fastening option is shown in FIG. 2 in the area of these sections 20a and 20b.
  • Another possibility is to have the secondary comminution device 32 protrude obliquely into the interior of the ejection tube 16 from the outer wall 28 at an angle which is favorable for the impact effect, as is shown in the example of a plate-shaped secondary comminution device 32a which at the same time ver in its longitudinal direction is displaceably displaceable in a guide 45 formed in the wall 28, so that the secondary comminution device 32 can optionally be retracted into an ineffective position if this is desired, for example when chopping grass or green corn.
  • Another possible arrangement is to arrange the secondary shredding device 32b so as to be adjustable about an axis 46 which is arranged in the region of the wall 28 and runs transversely to the conveying direction, so that the most favorable impact angle can be classified.
  • the impact angle can also be adjusted by adjusting the discharge flaps 20a or 20b when the secondary comminution device 32 is located at this point.
  • the secondary comminution device 32c is formed in the form of a roller, the profiles running in the circumferential direction of the roller.
  • the roller-shaped secondary comminution device 32c is mounted on the ejection tube 16 such that it can be rotated about an axis 48 which extends approximately in the region of the wall 28 transversely to the conveying direction and horizontally, the gradation of the profiles being selected such that on the peripheral portion of the roller surface facing the interior of the ejection tube 16 the profiles rise in the conveying direction of the chopped material out of the roller surface.
  • the roller-like shredding device 32c can either be loosely rotatably mounted, or else be provided with a drive, for example in the form of an electric or hydraulic motor, the direction of rotation of which is selected such that the circumferential section of the roller located within the ejection tube 16 moves counter to the conveying direction in order to intensify the impact effect.
  • a tube extension 50 can optionally be pushed over the end of the ejection tube, which, if necessary, picks up and forwards parts of the chopped material falling out of the ejection opening 18.
  • the arrangement of the secondary comminution device 32 in the region of the discharge flap 20 has proven to be particularly advantageous because, on the one hand, through the
  • Adjustment of sections 20a and 20b can be adjusted particularly easily, i.e. the most favorable impact angle, and results in optimal grain size reduction with a good throwing distance.
  • the sections 20a and 20b of the discharge flap can be easily removed if, for example, the effect of the secondary shredding device 32 is not required or desired when harvesting grass or green corn.
  • the invention preferably relates to a forage harvester, because the relatively low drive power requirement with optimal shredding has a particularly advantageous effect on the latter, the invention is also suitable for stationary shredders. So that the grains can be broken with the least effort, the width of the apex surfaces 36 of the profiles 34 should be less than the grain size. As a rule, the side edges of the apex surfaces will act on the grains.
