Definitions

  • the present invention relates to a root cutter with a horizontal knife-holding plate and, more particularly, such a root cutter intended to cut into fodder roots, such as beets, rutabagas, Jerusalem artichokes, etc.
  • a root cutter comprising a cylindrical hopper, a horizontal knife-holder plate provided with openings respectively associated with the knives, the knife-holder plate being carried above the bottom of the hopper and being able to rotate around a vertical axis, a member for driving said axis, and a chute for ejecting the chips opening tangentially between the knife-carrying plate and the rotating bottom of the hopper.
  • this root cutter is designed to cut waste and fragments of sugar beets, which are therefore relatively small.
  • a compression ramp is provided in the hopper.
  • Such a ramp is obviously not usable when it is necessary to cut whole fodder beets.
  • the evacuation of the pods is ensured by a lower turntable onto which the pods fall.
  • Such an evacuation means first projects the pods against the lower part of the side wall of the hopper where they agglutinate before exiting through a chute. In practice, this means does not allow the use of two discharge chutes ensuring equal flow therein.
  • modern barns most often have a central corridor bordered by two longitudinal troughs and it is advantageous to be able to pour pods in a single pass into these two troughs.
  • An object of the invention is to provide a root cutter provided with two chutes in which the flows can be equalized.
  • Another object of the invention is to provide a root cutter capable of cutting large whole roots, such as whole fodder beets.
  • Yet another object of the invention is to provide a root cutter transportable in particular by an agricultural tractor, whether the root cutter is stopped or in operation.
  • a root cutter comprising a cylindrical hopper, a horizontal knife holder plate provided with openings respectively associated with the knives, the knife holder plate being carried by a vertical axis above the bottom of the hopper, a vertical axis drive member and an ejection chute opening into the side wall of the hopper between the knife holder plate and the bottom of the hopper, a plurality of scrapers being suspended under the knife-holder tray with their lower edges practically scraping the bottom of the hopper.
  • the knife-holding plate comprises two knives and two associated openings, as well as two squeegees also respectively associated with the knives.
  • the horizontal angle between the blade of a knife and the radial direction of the associated squeegee is of the order of 150 °.
  • a stop bar just above the knife-holding plate, is fixed at two diametrically opposite points on the side wall of the hopper, a stop bar whose height is of the order of magnitude of the diameter of the roots to debit.
  • the root cutter is provided with two troughs located inside almost diametrically opposite sectors.
  • the root cutter of Fig. 1 comprises a cylindrical hopper 1 provided with a bottom 2, a knife-carrying disc 3 supported and driven in rotation by a shaft 4 passing through the bottom 2, a drive member 5 of the shaft 4 located under the bottom 2, a frame 6 supporting the bottom 2 and the drive member 5, and three feet 7 to 9 supporting the frame 6 above the ground.
  • the shaft 4 rotates around the axis of revolution X-X 'of the hopper 1.
  • the disc 3 is, inside the hopper, located a few centimeters, for example 10 cm, above the bottom 2.
  • the diameter of the disc 3 is, apart from the necessary clearance, equal to the inside diameter of the hopper 1
  • the disc 3 comprises two radial slots 10 and 11, diametrically opposite, in which knives 12 and 13 are mounted, the mounting of which will be described in more detail in relation to FIG. 4.
  • the disc 3 carries, under its lower face, two flat squeegees 14 and 15, the respective lower edges of which are a few millimeters from the bottom 2.
  • the squeegees 14 and 15 are, in the example of embodiment described, vertical rectangular plates whose vertical external edges project onto the cicular edge of the disc 3 and whose internal edges allow them to rotate around shaft 4 and its hub 16.
  • the frame 6 has the shape of a horizontal U, the two branches of which consist of parallel angles 17 and 18, and the base of an angle 19.
  • the bottom 2 of the hopper 1 is welded to the horizontal wings of the angles 17 to 19.
  • the distance between the branches 17 and 18 is such that the drive member is directly fixed thereon.
  • the branches 17 and 18 are bent diverging and carry hooks 20 and 21 which allow the attachment of the root cutter on the attachment bar of a tractor.
  • the feet 7 to 9 are respectively fixed under the front parts of the angles 17 and 18, and under the central part of the angle 19.
  • the frame has a ground clearance which allows the passage of a drive shaft articulated 22 between the member 5 and the PTO of the tractor.
  • the drive member 5 operates as a bevel gear and, optionally, as a speed reducer between the shaft 22 and the shaft 4.
  • the mounting of the disc on the shaft 4 will not be described in detail since this mounting is within the competence of the skilled person.
  • a vertical and diametral plate 23 whose height is of the order of the diameter of a beet or a little less.
  • the ends of the plate 23 are welded to the cylindrical inner face of the hopper 1.
  • the plate 23 is intended to serve as a stop to prevent the roots from rotating with the disc 3.
  • a oblique bar 24 located in the same diametral plane of the hopper 1 as the plate 23.
  • the bar 24 has its upper end which passes through the cylindrical wall of the hopper 1 and which ends in an eyelet 25. Its lower end is welded to the wall of the hopper, just above the plate 23.
  • the bar 24 can be round and serves as a tie to distribute the forces when the root cutter is worn the three-point attachment system of a tractor to which the root cutter can conventionally be attached by hooks 20 and 21 and the eyelet 25.
  • the plate 23 is on this axis, as well as the projection of the shaft 4, and the branches 17 and 18 are parallel to it.
  • the root holder is completed by two troughs 26 and 27 whose entrances are, as shown in FIG. 1 for the trough 26, located in the cylindrical wall of the hopper 1 between the underside of the disc 3 and the bottom 2.
  • the troughs 26 and 27 are not symmetrical with respect to the axis Y-Y ', which will be explained below.
  • the blade of the knife 12 which protrudes slightly above the level of the disc 3, cuts the bottom of a beet 28 which is wedged against the plate 23, while the disc 3 rotates in the direction of the arrow F.
  • the gap between the bottom of the plate 23 and the disc 3 is obviously sufficient for the knife 12 to pass freely.
  • the cap 29, which will be detached by the blade of the knife 12, will fall on the bottom 2.
  • a reversible knife 12 has been shown with two blades which can be fixed obliquely to the disc in one edge of the slot 10 by means of screw-nut systems, but it should be understood that this is not that of an exemplary embodiment and that variants are possible without departing from the scope of the invention.
  • the mounting of the knife 13 is obviously similar to that of the knife 12.
  • arrow F indicates the direction of rotation of the disc 3. It appears there that the strip 12 is cutting pods in the beets which rest on the disc between itself and the rear part of the plate 23 while the knife 13 is in the process of cutting chips in the beets which rest on the disc between itself and the front part of the plate 23. knives under the plate 23, their roles are exchanged.
  • the cut pods fall on the bottom 2 where we can distinguish a first angular sector going from the end - seen in the direction of rotation of the disc - of the opening of the chute 26 and the end of the chute 27 and a second sector going from the end of the chute 27 until the end of chute 26.
  • the squeegee 14 ejects the chips towards the chute 27 while in the second sector the squeegee 15 ejects them towards the chute 26.
  • the squeegee which follows a knife is behind him by more than 100 ° for example. This allows the pods to have fallen to the bottom before being scraped off.
  • the angles of the two sectors are not equal. Indeed, the orientation of the chute 26 makes with the direction of advance of the root cutter an angle of 135 ° while that of the chute 27 makes an angle of 270 °, the disc rotating in the trigonometric direction. As a result, the drop points on the ground of the pods ejected from the chutes are practically symmetrical with respect to the axis Y-Y '.
  • FIG. 5 shows how the pods 29 are pushed into the chute 26 by the squeegee 15 in order to fall into a trough 30.
  • the outlets from the troughs 26 and 27 can be orientable so as to eject the pods more or less far laterally.
  • they are provided with means allowing them to be closed selectively when it is desired to feed only one side of the root cutter.
  • the root cutter is loaded with beets, for example, when it is placed on the ground on its feet 7 to 9, by means of a bucket mounted at the front of a tractor.
  • the root cutter is hooked to the three-point system of the tractor by the hooks 20 and 21 and the eyelet 25, and the shaft 22 is connected to the PTO of the tractor.
  • the PTO is engaged, which causes the beets to be cut.
  • the tractor moves forward to distribute the pods evenly. Note that the spacing between the drop points of the pods can be, to a certain extent, adjusted by raising the root cutter more or less.
