Definitions

  • the present invention relates to an arrangement for a roller which exhibits moving roller sections , which sections are capable of actuation by means of fluid-operated piston cylinders.
  • the principal object of the present invention is in the first place to provide an arrangement of the kind indicated above which , amongst other t ings, affords the possibility of effectively achieving by simple means the desired uniform roller pressure in the various roller sections. Said object is achieved by means of an arrangement of the kind defined in the filed Patent Claim 1, which is characterized essentially in that each piston cylinder, which is so arranged as to force a roller section against the ground, is capable of being connected to a connection provided for the supply of fluid, and in that each fluid supply connection is connected to a spring arrangement provided for said fluid.
  • Fig. 1 shows a perspective view of an arrangement for a tractor-drawn three-section roller, with the roller sections folded down into the rolling position;
  • Fig. 2 shows the roller and the arrangement viewed from the rear with the roller section in the folded-up position
  • Fig. 3 shows a diagrammatic flow chart for an arrangement.
  • a previously disclosed roller 1, to which an arrangement 2 in accordance with the present invention can be applied, comprises a central roller section 4 supported by a fixed frame 3 and a moving side roller section 7, 8 situated on each side of the fixed and supported central roller section 4 and supported preferably on an articulation 5, 6, which side sections in turn each contain their own moving side arm 9, 10.
  • Each moving side roller section 7, 8 is attached to one end 11A, 12A of a fluid-operated piston cylinder 11, 12, whilst the other end 11B, 3 via an articulation 13, 14.
  • the fluid accommodating space 15, 16 in each of said piston cylinders 11, 12, which is situated on one side of the appropriate piston 17, 18, is connected in a previously disclosed fashion via a common pipe 19 to a fluid accommodating container 20A or some other source of fluid situated, for example, on a tractor or some other towing vehicle 20.
  • a fluid accommodating container 20A or some other source of fluid situated, for example, on a tractor or some other towing vehicle 20.
  • Each fluid accommodating space 21, 22 of the piston cylinders in question, which is situated on the opposite side of the appropriate piston when considered in relation to the spaces 15, 16, is so arranged in accordance with the present invention as to be capable of being connected to a connection 23 for the supply of fluid, which fluid is necessary in order to force said moving side roller sections 7, 8 against the ground 24 along which the roller 1 is so arranged as to be capable of being advanced, preferably in the form of a hydraulic fluid.
  • Said connection 23 comprises in accordance with the preferred illustrative embodiment a pipe leading from preferably the above-ment oned fluid accommodating container 20A, which pipe branches to the respective piston cylinders 11, 12.
  • the arrangement appropriately comprises pressure-sensing means, such as a manometer or some other means which permit manual and/or automatic recording of the pressure in each supply connection 23 to the piston cylinders, for example as shown in Fig. 1, with a manometer 29 capable of being connected into a circuit 30 providing a connection to a compressed fluid supply line 23 of the aforementioned kind.
  • pressure-sensing means such as a manometer or some other means which permit manual and/or automatic recording of the pressure in each supply connection 23 to the piston cylinders, for example as shown in Fig. 1, with a manometer 29 capable of being connected into a circuit 30 providing a connection to a compressed fluid supply line 23 of the aforementioned kind.
  • each fluid supply connection 23 is also connected to a spring arrangement 31 acting as a damper, which arrangement is intended for the fluid which is present in each of the aforementioned connections 23.
  • the suspension arrangement 31 includes a container 32 which is divided up internally by means of a moving device 33 or the like, preferably a wall, accommodated inside the container 32, which device is so arranged as to be capabLe of providing a seal against a volume of gas 34 or other fluid which is enclosed within a limited space 35 inside the container 32, which space 35 is limited by the wall 33 of an accommodating space 36 for the fluid in the connection 23.
  • Means can be provided for this purpose so arranged as to enable the gas volume, etc., to be varied, that is to say means for the introduction or release of gas into or from the space 35.
  • Spring devices of a kind other than the gas spring described above may, of course, be used for the arrangement 2 in accordance with the invention, for example coil springs or rubber springs.
  • the function of the arrangement described above is as follows: in order to set the desired pressure Leading for each roller section 7. 4, 8, the roller can be driven cnto separate weig i ng machines for each roller section 7, . 8, so that, by supply i . g an appropriate quantity of fLuid via each ccrnecticn frcm the container 20A_ the desired pressure Loading can be achieved for each roller section 7, 4, 8. An identical pressure may appropriately be set for all the roller sections 7, 4, 8.
  • the arrangement 2 in accordance with the present invention is such that the roller sections 7, 4, 8 will, on encountering hard lumps of soil, etc., be able to pass over the lumps of soil in question as a unit so as to be able to crush said lumps of soil, or so as to roll down hard stones, for example, into the ground.
  • All the roller sections 7, 4, 8 in this way constitute a body which is to all intents and purposes rigid. This is made possible by the fluid connections 23 for the moving sections 7, 8 of the roller being connected to a spring arrangement 31 of the kind indicated above.
  • Said connections 23 can be so arranged for this purpose that the fluid inside them will not, in the presence of rapid actuations of the roller sections 7, 4, 8, manage to transfer movements from the roller sections 7, 8 to the spring unit 31 in order to be able to swing said actuated roller section separately upwards.
  • the roller 1 When driving with the roller 1 in areas which exhibit a progressive transition from one slope of the ground to another or, as already mentioned, at low speeds, the roller 1 can be made, thanks to the invention, to behave sensitively and with identical ground pressure over the entire working width of the roller.
  • Swinging up of the moving roller sections 7, 8 is achieved in a previously disclosed fashion by the supply of fluid in the direction of the arrows 37, via the appropriate line 19.

Abstract

Agencement de rouleau présentant un certain nombre de sections de rouleau mobiles, ces sections pouvant être actionnées à l'aide de cylindres de piston actionnés par un fluide (11, 12). L'agencement permet, entre autres, de réguler la pression désirée des rouleaux de manière simple et efficace et de permettre la suspension des sections de rouleau. Chaque cylindre de piston (11, 12), destiné à appliquer de force une section de rouleau contre le sol, peut être relié à un raccord (23) d'alimentation en fluide, chaque raccord d'alimentation en fluide (23) étant en outre relié à un agencement à ressort (31) prévu pour ledit fluide.
