Definitions

  • the present invention relates to an agricultural machine for soil cultivation having the features of the preamble of claim 1.
  • the invention further relates to a method for the variable adjustment of the agricultural machine having the features of the preamble of claim 7.
  • Discs for soil cultivation are available in various arrangements, such as e.g. in classic disc harrow in so-called X or Y arrangement.
  • the discs i.d.R are mounted side by side on shafts, the entire waves each at min. 2 points are stored.
  • Disc arrangements in which individually mounted discs are arranged next to one another are known as so-called short disc harrows. These are used in tillage machines as well as in seed drills.
  • suspensions of entire disc shafts are mainly used with the aid of e.g. Leaf spring systems used.
  • each individual disc is suspended from a frame.
  • the suspension takes place by means of spiral spring systems, rubber spring elements or leaf springs.
  • the depth adjustment of the pulley systems takes place on complete pulley shafts via an adjustable chassis or an adjustable support roller.
  • the object of the invention is to provide a compact disc harrow element, a so-called disc harrow, for heavy, deep tillage.
  • a cultivation of the soil is to be possible to about 25 cm depth.
  • the discs must not move during work. However, the discs must be able to avoid stones or other obstacles.
  • the depth In order to enable as universal a use as possible, the depth must continue to be infinitely adjustable.
  • the invention describes an agricultural machine in the form of a disc harrow, in particular a short disc harrow.
  • the disc harrow comprises a main frame and at least one carrier, wherein a plurality, ie at least two, of discs are attached to the carrier.
  • the discs are arranged side by side on the carrier and form with this a rigid unit, the so-called disc system.
  • This unit is rotatably mounted on this via firmly connected to the main frame connecting elements and the depth adjustment of the Schei- ben can be adapted to the requirements of the soil or adjusted accordingly
  • the support may be, for example, a pipe, a rod, an axle, etc.
  • the individually mounted discs are firmly / rigidly connected to each other.
  • the rigid element may also be designed in the form of a disk shaft.
  • the rigid element is rotatably supported by a connecting element on the base frame of the disc harrow.
  • a connecting element on the base frame of the disc harrow.
  • Several rigid elements can be connected together to form a larger unit.
  • various arrangements are possible in which the elements are joined together next to each other or in any number and / or arrangement.
  • the individual elements can be made individually adjustable here.
  • the base frame consists of frame struts along the direction of travel and stabilizing cross connections. Between such a transverse frame member and a rigid element may be a spring mechanism. About this, the rigid element can be mounted resiliently rotatable.
  • the spring mechanism is, for example, a spring package.
  • the suspension may be hydraulic or mechanical, e.g. Hydraulic cylinders with a pressurized bladder, spiral springs by means of a steel spring or similar, rubber springs etc. can be used.
  • the spring assembly may be biased.
  • the bias ensures that the discs do not move uncontrollably while working.
  • a change of movement is possible when external forces act. For example, a rotational movement of the disk carrier and thus an evasion of the disks is triggered by stone load. This is important so that the discs are not damaged by stones or other hard obstacles in the ground.
  • the spring pressure i. the release pressure for the discs is fixed.
  • the spring pressure can also be adjustable.
  • a disk encounters a solid obstacle, for example a stone
  • the entire disk element is influenced due to the coupling of several disks to a carrier, so that all disks avoid the obstacle as a result of the forced rotational movement of the carrier. If there is no obstacle, this will be reversed Disc element due to the preset bias back to the starting position.
  • a change in the spring length causes a rotation of the disk carrier. This will change the position of the discs relative to the ground.
  • an extension of the spring causes lifting of the discs, while a shortening of the spring rotates the carrier so that the discs attached thereto penetrate deeper into the ground.
  • the discs may also be arranged on the carrier so that, when the spring is extended, the discs penetrate deeper into the ground and, when the spring is shortened, lift the discs off the ground accordingly.
  • each element is assigned its own spring mechanism.
  • These spring mechanisms can be set differently.
  • the release force of the spring element of the front could differ from the release force of the spring element of the rear row.
  • the release force of the rear row could be set larger, because the floor has already been pre-machined using the front row of windows.
  • the various disk elements in height can be set independently or dependent on each other.
  • both the depth adjustment, the excavation of the working setting of the discs and the Federvorspan- voltage can be adjusted by means of the spring element.
  • the functions height adjustment and spring preload of the disc elements can be designed independently or coupled together.
  • the depth adjustment or the excavation from the working setting of the discs is carried out as already described above by an extension or shortening of the spring in the spring mechanism.
  • the disk system can be combined with various elements such as tines, rollers, harrows, etc. or used as a disc harrow as a solo.
  • the pulley system can be used in three-point devices or in towed devices in various working widths.
  • the disk carrier and the main frame and the main frame and the chassis form a rigid unit.
  • no adjustment is made to the depth setting.
  • the depth adjustment takes place in this case via the rear hydraulics of the tractor or is completely omitted. If the chassis and frame form a rigid unit, the excavation takes place from the ground via a rotation of the rigid units.
  • Fig. 1 shows a side view of a drawn short disc harrow
  • Fig. 2 shows a perspective view of a pulled short disc harrow from obliquely behind
  • FIG. 3 shows a representation of a pulled short disc harrow from above.
  • a short disc harrow with disks 20 connected via a carrier is illustrated with reference to FIGS. 1 to 3.
  • the short disc harrow 10 consists of a base frame 40, 42, on which the disc harrows 20 are suspended via a rotatably mounted carrier 22 and form a rigid element 18.
  • a plurality of disks 20 are fastened to the carrier 22.
  • the individually mounted discs 20 are fixed / rigidly connected together.
  • the base frame consists of frame members 40 along the direction of travel of the machine and of transverse struts 42 for stabilization and attachment of other functional elements.
  • the disk carrier 22 may, for example, have the form of a pipe, a rod or an axle.
  • the discs 20 may be mounted within the disc elements 18 in the form of a disc shaft.
  • the rigid element 18 is rotatably supported via a connecting piece 31 in FIG. 32.
  • a spring mechanism 30 via which the rigid element 18 is mounted torsionally sprung.
  • This is, for example, a spring assembly, which may be designed as a hydraulic cylinder with a pressure bladder, a spiral spring by means of a steel spring or the like, a rubber spring or the like.
  • the spring pack 30 may be biased.
  • the bias causes the discs 20 to not move during work. A movement change or rotational movement is triggered only by stone load.
  • the spring pressure, i. the trigger pressure for the discs 20 is fixed. According to a further embodiment, the spring pressure can be adjustable or adjustable.
  • a complete element 18 is sprung such that the spring mechanism 30 causes a rotational movement of the element 18.
  • the carrier 22 With an extension of the spring, the carrier 22 is rotated so that the discs 20 are pushed away upwards.
  • a shortening of the spring causes a deeper penetration of the discs 20 in the ground.
  • a plurality of elements 18 can be joined together next to each other or one behind the other in any number and / or arrangement.
  • the release force for the various elements 18 can be set different from each other.
  • the release force of the spring element 30 of the first can differ from the release force of the spring element 30 of the second row.
  • the disc elements can also be adjusted in height (the angle of rotation) independently or dependent on each other.
  • the functions height adjustment and spring preload of the disk elements can be designed independently of each other.
  • the disc elements 18 may be cantilevered, wherein the rotation axis 22 itself forms the frame.
  • discs 20 can be mounted in any shape or size. Furthermore, the distances between the discs 20 and the angle settings are arbitrary selectable and adjustable. Thus, the system can be optimally adapted to the soil and work requirements.
