Definitions

  • the invention relate to a method for whole straw reaping of corn or other crops, that is to say the reaping of grain and straw and husks o the corresponding growth components of crops which do not comprise cereals, in which a machine is provided to cut the corn which is fed into a chopper, in which the corn is chopped up into short lengths.
  • the invention also relates to a reaping machine for the carrying out of the method.
  • the corn is cut off by a cutting device and transported across a cutting table via an elevator to a cylinder with beater shoes.
  • the grain is threshed out, after which the grain is separated from the straw and husks in straw shakers and cleaning mechanisms.
  • the straw can be processed in different ways, e.g. it can be laid back on the field, possibly after fine chopping, or packed into bales.
  • the purpose of the invention Is to provide a method and a reaping machine which largely eliminate the problems mentioned above and the restrictions imposed by existing methods and machines.
  • this can be achieved in that the majority of the grains, when the corn is threshably is threshed out immediately prior to chopping the corn into small pieces.
  • the corn may be chopped into pieces by means of a nu ber of knives on a rotating cylinder against a fixed cutter blade, while the majority of the grains are threshed out by means of a number of beater shoes on the same cylinder, the corn without cutting being beaten against the fixed cutter blade by the beater shoes.
  • the reaping machine herein comprises a rotatably cylinder with an horizontal axes, a number of knives and at least the same number of beater shoes distributed around the periphery of the cylinder such that at least one beater shoe and preferably several beater shoes are provided between each of adjacent knives, and wherein the beater shoes extend in the radial direction slightly less then the knifes do, and a fixed cutter blade is provided as a counter knife for the knives as these by shering cut the corn and as a dolly as the beater shoes beat the corn in the direction of rotation of the cylinder.
  • the knives are conveniently arranged in replaceable holders on the cylinder, such that they arranged in their holders may be reground to the desired knife height outside the machine.
  • Fig. 1 gives a side view which illustrates the machine in accordance with the invention
  • Fig. 2 gives a side view of a threshing and chopping cylinder forming part of the machine
  • Fig. 3 shows on a larger scale and in sectional view a portion of the said cylinder viewed the axial direction
  • Fig. 4 provides a view IV-IV in Fig. 3.
  • a machine housing is generally designated as 1.
  • the machine housing 1 there is a cylinder 2 with horizontal rotating shaft, the cylinder hub being designated as 3.
  • the cylinder hub On the underside of the cylinder 2 there is a piece of plate 4 which forms the base of the machine housing.
  • Two girders for mounting the machine housing 1 on a working vehicle have been designated as 5 and 6.
  • the feeder portion 7 of the machine housing 1 two feeder rolls 8 and 9 are provided.
  • the upper roll 8 is provided with teeth whilst the lower roll 9 has a smooth surface, all with the objective of providing more efficient feeding.
  • an elevator 10 of conventional design.
  • a base plate in the elevator 10 is designated as 11, a number of endless chains provided with fingers are designated 12 and a guide roll is designated 13.
  • the cylinder 2 is divided up into a number of sections A-F , which are separated by end plates 14 and intermediate walls 15, Fig. 2.
  • the plates 14, 15 are welded to the hub 3.
  • six knife holders 16 are provided in each section A-F between the end plates 14 and the adjacent intermediate walls 15, or between adjacent intermediate walls 15, six knife holders 16 are provided.
  • the knife holders 16 are screwed to lugs 17 on the sides of the intermediate walls 15 of end plates 14 by means of bolted connections 18, Fig. 3 and Fig. 4.
  • the knife holders 16 consist of an element of essentially parallel-epipedic shape and with a length which extends over the length of the cylinder section.
  • the knife holders 16b in the section B are somewhat displaced in relation to the knife holders 16 in section A.
  • the knife holders 16c are displaced in a corresponding manner with respect to the knife holders 16b etc., as indicated in Fig. 2.
  • the location of the knife holders 16 in the cylinder 2 is defined by reference planes 31 and 32 which are plane surfaces in pairs of common planes on lugs 17 which are related pair-wise.
  • the location of the knives is governed by threaded holes provided for the screws 18.
  • the line of intersection 34 is parallel with the axis of rotation of cylinder 2, which signifies that also the reference planes 31 and 32 and the corresponding surfaces of the lugs 17 are so machined that they are parallel with the axis of rotation of cylinder 2.
  • a dash-dotted line symbolises an imaginary plane 33 which includes the line of intersection 34 and the axis of rotation of cylinder 2.
  • the angles ⁇ and ⁇ in Fig. 3 are identical for all knife holders 16.
  • the angle ⁇ is the angle which is formed between the reference plane 32 and the imaginary plane 33.
  • the angle ⁇ is the angle between the reference plane 31 and the imaginary plane 33.
  • d the distance between the reference plane 31 and the edge of knives 20 is designated as d.
  • the distance d can, in conjunction with the grinding of the knives which during this are mounted in the holders 16, be maintained without difficulty so that the distance d is kept within close tolerances.
  • each section A-F there are also arranged a number of beaters or beater shoes 25.
  • the beater shoes 25 consist of radial plate sections welded between the intermediate walls 15 or end plates 14 and the adjacent intermediate wall 15 resembling fan blades in an impeller.
  • the radial extent of the beater shoes 25 is somewhat less than the radial extent of the knives 20. The difference in the radial direction has been designated as d, Fig. 3.
  • a fixed cutter blade 27, Fig. 1, is also provided which can be removed through an aperture 28 in the end wall of the machine housing 1.
  • a knife holder is designated as 29.
  • the functioning of the reaping machine is as follows.
  • the com is initially inserted in a known manner against a knife table, not shown, with an elevator and is cut off close to the ground surface by a knife.
  • the cut off corn is then fed towards the centre of the machine, which can take place using devices which form part of state of the art, after which the corn which is concentrated towards the centre is fed upwards in the elevator 10 by means of the endless chains and their fingers, which press the corn against the baseplate 11 in elevator 10.
  • the feeder section 7 the corn is fed with the ears first into the roll nip 30 between the two feeder rolls 8 and 9, and from the roll nip 30 the corn is fed, still with the ears first, outwards across the fixed knife 27.
  • the ears When the ears have passed the knife 27 in the majority of cases they meet some of the threshing shoes 25 and are beaten by this threshing shoe, the threshing effect being amplified in that the ear is also affected by the oppositely-directed impact force from the fixed cutter 27.
  • the beater shoe 25 then passes by the edge of the fixed cutter blade 27 which faces the cylinder without the grain in the ear being damaged. The cutting off of the ear and of the remaining portions of the straw then takes place only after one of the knives cuts off the ear/straw against the fixed cutter blade 27.
  • beater shoes 25 are arranged more closely together and/or by arranging a further beater shoe directly in front of each knife.
  • a knife When a knife is to be reground (sharpened) the complete knife holder 16 is released, and then a spare knife holder with a new or reground knife can be inserted immediately in place of the first knife and knife holder.
  • the arrangement of releasable knife holders facilitates the possibility of grinding the knives outside the machine to the right height relative to the fixed cutting blade and by this means pre-adjusting the cutting blade to a fixed dimension. This means that outrage times on the part of the machine can be reduced considerably, whilst at the same time the power demand can be reduced because of the high precision achievable as regards the setting of the cutters.
  • the beaters/beater shoes 25 functioning as the impelling device. Since the knives 16a, 16b, 16c, etc. in the various sections A-F are mutually displaced, the mode of opera tion of the machine is extremely smooth, which also contributes towards reducing the power demand.
