Definitions

  • the invention relates to a method for producing high-density cylindrical compacts from loose stalk material, such as hay or straw, which is continuously taken up and compacted to form a rotating press strand which flows continuously in the axial direction, with individual press strand sections (compacts) successively ending from the front end of the press strand. be separated.
  • the invention further relates to a pick-up press working according to the winding principle for producing high-density cylindrical compacts from loose stalk material, such as hay or straw, or from other materials, in particular for carrying out the above-mentioned method, consisting of one end face formed by a plurality of pivotable press rolls open winding space to be loaded on the circumferential side to produce a press strand flowing out in axial and continuous feed on the open end face and a separating device for dividing the press strand into individual compacts.
  • the invention is thus based on the previously known briquetting presses, the term “compact” used above being used for the highly compressed stalk crop briquettes produced by a briquetting press, which usually have a diameter of 10 to 15 cm and a length corresponding to this diameter.
  • the density of such straw briquettes is between 350 and 500 kg / m3, in extreme cases even around 800 kg / m3.
  • a briquetting press of the type described in the introduction can be found, for example, in US Pat. No. 3,244,088.
  • the changing room is e.g. formed by six press rolls that can be pivoted with respect to the winding space axis.
  • the winding space is to be given a slightly conical design in order to facilitate the exit of the rotating press strand which is continuously axially conveyed out of the winding space.
  • the pressing strand emerging from the winding space is separated into individual briquettes directly behind the winding space by a separating device, the length of which in the exemplary embodiment shown can also be shorter than its diameter.
  • a comparable briquetting press can be found in DE-A-1 176 418.
  • the winding space is formed by four or five press rolls, which define a conical winding space and are subject to a positive drive.
  • the wound material is continuously rotated out of the winding space and pressed into a cylinder, where it is braked by adjustable springs. Cylinders and springs rotate in the same sense and at the same speed as the material flow.
  • Handy briquettes are then separated from the material strand, with the help of tear-off teeth, which reach through the longitudinal slots of the cylinder jacket.
  • the springs mentioned also serve the purpose in the Retain the remaining wrapping bale against the action of the tear teeth.
  • DE-A1-36 09 631 also discloses a comparable briquetting press, in which separating knives are successively pressed radially into the press strand emerging from the winding space, which protrude radially from a cutting wheel which is carried along by the knives from the feed of the press strand and thereby cuts compacts .
  • the knives With this entrainment of the cutting wheel, the knives are pressed relatively slowly into the press strand, which is carried for this purpose by two pairs of conveyor rollers.
  • the conveyor rollers thus form the abutment for the considerable pressure to be applied by the knives. This pressure is difficult to absorb by the conveyor rollers, since gaps must necessarily remain between the conveyor rollers, through which the stalk material of the press strand can be squeezed. This results in the risk of the press strand or the briquettes being dissolved.
  • roller bale presses belong to a machine category to be distinguished from the briquetting presses. These presses, which are widely used in practice, produce roller bales that usually have a diameter of 100 to 150 cm and a dry matter density of only about 100 to 120 kg / m3.
  • DE-A2-2 443 838 a discontinuously operating roller baler, in which the finished bale located in the wrapping room is wrapped several times with a binder, a thread or a mat made of net or film. The wrapped bale is removed from it by pivoting the rear part of the wrapping space housing; then the changing room is closed again. The machine must be brought to a standstill during the setting and opening and closing of the changing room.
  • EP-A3-0 268 002 discloses a continuously operating roller baler, the conical press space of which is formed by a plurality of press rolls, for example 16.
  • the baling chamber which is open on the end face of larger diameter and is to be loaded on the circumferential side, is used to produce a press strand flowing out on the open end face in axial and continuous feed, the diameter of which corresponds to that of conventional roller bales.
  • a cylindrical conveyor section Directly downstream of the exit from the press chamber is a cylindrical conveyor section, the jacket of which is formed by driven conveyor rollers, which are arranged with their axes of rotation parallel to one another and together define a conveyor channel, the diameter of which approximately corresponds to that of the press strand emerging axially from the press chamber.
  • a binding device is provided for binding the press strand, which is still under radial pressure, during its axial advance with a binding agent fed between two of the said conveying rollers.
  • a separating device followsed up the binding device Tet is a separating device, which can either be arranged in the area of said conveyor section or directly behind it.
  • the invention has for its object to develop a method and a device with which compacts, that is, highly compressed stalk briquettes can be produced, which are so dimensionally stable that the length of the compacts produced can be a multiple of their diameter.
  • the object underlying the invention is achieved with respect to the device in that the winding space has approximately the same diameter over its axial length, and that in front of the separating device in the end region of the winding space, but at least immediately behind the winding space, a binding device for tying the press strand still under radial pressure during its axial feed with a binder supplied under tension as a thread, tape, net or film, made of plastic or other, for example feedable material is arranged, with a single winding unit being able to produce dimensionally stable compacts, the length of which corresponds approximately to their diameter (straw briquettes) or is a multiple of their diameter (compact rolls).
  • a completely new product can thus be produced, which can be called a compact roll, which is also intended to be covered by the term "compact".
  • This is a product which has the high density of the previously known stalk briquettes, but can be produced in a length of several meters due to the dimensional stability which has so far not been achievable, but surprisingly achieved according to the invention.
  • the compact rolls consist of material that can be ensiled, such a compact roll can produce excellent silage as a result of the extensive opening of the straws, which is advantageous in terms of feeding technology and associated with pressing, and due to the density in the compact roll, which is about twice as high as in conventional chopped material silos.
  • the silage quality can be further improved by connecting a processing device, for example a pair of squeeze rollers, upstream of the winding unit.
  • a processing device for example a pair of squeeze rollers
  • caps for example made of film or plastic
  • machine-made "small silos" can be produced in the form of compact rolls.
  • the wrapping briquettes or the compact rolls because of the tying that takes place before they are separated from the press strand, take away the possibility of loosening up during the severing or subsequent handling or even dissolve, so that centrifugal forces and especially those when cutting or at the subsequent destructive influences that occur later are completely eliminated.
  • the stem length does not matter at all, which in the known continuously operating winding briquetting presses must not be less than a critical length because of the internal cohesion of the winding briquettes required for this, so that in particular briquetting of Grummet was practically impossible.
  • the device it is particularly advantageous that one and the same machine can be used to produce either high-density stalk briquettes or high-density compact rolls of different lengths. Both options lead to a reduction in transport and storage space requirements to 1/3 to 1/4 of the values usual for roller bales.
  • the machine according to the invention allows a continuous mode of operation with only a single wrapping unit.
  • the solution according to the invention for the device with a constant wrapping space diameter follows the opposite tendency, as is common today in the construction of roller balers. While according to the invention the size of the compacts can be varied by changing their length, the tendency has prevailed in roller baler construction with a single one Machine roll to produce bales that have different diameters with the same roll bale length.
  • the separation of a compact takes place as a function of a measurement of the extruded strand feed that is carried out continuously. It is advantageous if the feed measurement mentioned is used to control the extrusion winding.
  • the wrapping of the press strand is preferably carried out continuously helically, which is preferably designed according to the device according to the invention such that the binding device arranged fixed to the frame automatically wraps the press strand continuously with the binder through the rotation and the advance of the press strand in a helical manner.
  • the frame-fixed binding device which together with the axial advance of the press strand leads to automatic, helical wrapping of the press strand, on the one hand there is a simple construction and, on the other hand, a low binder requirement, since the individual turns of the binder have a corresponding effect, particularly when processing longer crops Can keep distance from each other.
  • a tape is used as a binder, there is the advantage that it can be wound with only a small distance in terms of its windings, so that there is practically a single-layer covering of the compact.
  • the pressing strand is wrapped discontinuously using a binder, the width of which covers a substantial part of the length of the compact.
  • the binder here can in particular be a mesh or a film. Because this is a tight over coverage of the compact with the binder, this type of wrapping is particularly advantageous for particularly short crops.
  • the binding device In order to avoid that the binding device continues to work unnecessarily in the event of failure of the press strand feed, it is advantageous if the wrapping of the press strand is interrupted if the press strand feed fails.
  • the binding device can be switched off manually or automatically.
  • the separating device In order to allow the separating device to interact harmoniously with the advance of the press strand, it is advantageous if the separating device consists of a pivotable separating element (rotating cutting disc, oscillating separating knife, double-knife cutting mechanism, chainsaw), which is coupled to the press strand during the separating process in such a way that that it participates in its feed, and its pivoting can be controlled so that compacts of different lengths (stalk material briquettes, compact rolls) can be separated. Due to this running of the separating element with the press strand, there is no axial jamming between the separating element and the press strand. The separating element cuts into the pressed strand, which is kept in shape by the binding, with simultaneous separation of the binding, the binding of the separated compact being retained on the crop.

  • a trigger wheel driven by the feed of the press line can preferably be arranged in the axial plane of the press line, which carries circumferential star wheels arranged perpendicular to its plane, which the Start rotation of the press strand.
  • a device which pivots the press rolls in dependence on the press pressure in the winding space, the control preferably taking place in dependence on the drive torque of the press.
  • a removable elevator or a removable throwing device for conveying the crop briquettes can be arranged on the frame of the collecting press.
  • These additional organs are only required if the stalk briquettes are not to be thrown directly onto the ground.
  • the pick-up press shown in the examples of FIGS. 1, 2 and 3 consists (FIG. 1) of a winding unit 1 with a plurality of press rollers 2, which form the winding space 3 represented by the dash-dotted circular line.
  • the stalk material picked up by the collector 4 is fed to the winding space 3 via the feed screws 5, the pair of pre-press rollers 6 and the feed roller 7.
  • the pressing rollers 2 are driven from the tractor PTO shaft 8, the chain drive 9 and the cardan shafts 10.
  • the pressing rollers 2 are known from the device in a known manner as a function of the pressing pressure in the winding room in Fig. 2 axis-parallel position pivoted out so that their axes are at an oblique angle to the winding space axis. For reasons of clarity, this pivoting of a few degrees is not shown.

  • the binding device 12 is arranged immediately behind the changing space 3; it has the mechanically driven or loosely rotating guide rollers 13 (FIG. 2) driven by the rotating press strand 11, to which the binding agent, a thread or a narrow band 15 made of net or film is fed from a supply reel 14.
  • the binder automatically and continuously wraps around the press strand 11.
  • the helical binding can be predetermined in dependence on the speed and feed of the press strand 11 so that the band edges slightly over rag.
  • a separating device 16 for example by a pivoting and during the cutting process participating in the advance of the extrudate 11 rotating cutting disc 33 (Fig. 6 and 7) - in any length compacts (11 a in Fig. 2 or 11 b in Fig. 4) divided.
  • the desired length of the compacts is set and measured using a release wheel 17 (see description of FIGS. 6 and 7).
  • Fig. 3 shows a pick-up press, in which the binding device 12 is not arranged outside the changing room, but in the last part of the changing room itself. As a result, the guide rollers 13 (FIG. 2) can be saved .

  • a thread provided with barbs or a narrow band 15 made of net or foil is used for binding.
  • continuous swath picking such a binder 15 wraps the press strand 11 automatically and continuously without interruption. With shorter interruptions in the crop supply and thus the extrusion feed - such. B.
  • the binder supply does not need to be interrupted, since the somewhat larger number of layers then occurring at one point of the compact does not later have a disruptive effect, and since the resulting increase in binder 15 consumption is only insignificant.
  • the tape feed is interrupted by a manually or automatically operated device; by means of the same device, the strip 15 is then fed to the press strand 11 again when the crop is supplied again.
