Definitions

  • the invention relates to a disc harrow.
  • a harrow is the most widely used field implement in agriculture after plowing. It loosens the soil, mixes fertilizer and soil, crumbles the soil, covers the seeds and fights weeds that accumulate before and after sowing.
  • the original form of a harrow consists of tapered teeth pulled through the ground. Linguistically, the name is attributed to the Indo-European ok, which means "pointed.”
  • Modern harrows consist essentially of one or more, on a pull rod, the so-called harrow beam, attached, forming Eggenfelder frame with mostly from the directed, pointed teeth Teeth are preferably arranged on a gap.
  • the invention has for its object to provide a disc harrow improved effectiveness. This object is achieved by the invention defined in claim 1. Further developments of the invention are characterized in the dependent claims. As a result, an improved, increased use of a disc harrow is achieved.
  • the invention consists in a disc harrow mounted on a frame, curved, smooth or serrated hollow discs therein that the frame several disc batteries are fastened with only a few, for example, four rotatable hollow discs.
  • the disc batteries are rotatably mounted about vertical axes.
  • the pivot points of the disc batteries are directly above the axis of rotation of the shaft around which rotate the hollow discs.
  • the disc battery can be rotated by desired angle, for example, 10 ° -15 ° continuously and formed lockable in the positions.
  • the angle (s) can be adjusted according to the working conditions.
  • the frame or frames have mutually parallel frame parts, which are substantially perpendicular to Direction of travel of the harrow are arranged and are designed as support tubes.
  • disc batteries are mounted on both supporting frame parts.
  • the number and width of the adjacent disc batteries is a measure of the working width.
  • the number of consecutive and thus consecutively running support tubes and disc batteries is a measure of the length of the implement. It determines the effectiveness of the harrow on the ground.
  • the disc batteries are arranged offset in the direction of travel behind one another support tubes against each other, so that the hollow discs are effective on gap.
  • each disc battery is connected to the frame via a steel leaf spring to the frame. By attaching several disc batteries side by side, a large working width can be achieved.
  • a frame for holding the disc batteries may also have more than two parallel support tubes. On a subsequent support tube, the disc batteries can be pivoted through 180 °.
  • the front hollow discs throw the floor to the left or right and the rear discs to the right or left.
  • the front and rear disc batteries can be adjusted in their lateral position so that overall optimal soil tillage is effected.
  • the cutting angle of all disc batteries can be infinitely adjusted via a control linkage of 0 ° to 15 ° or more.
  • Such a disc harrow can be operated on the towing drive unit, the tractor, in conjunction with bar rollers or other suitable agricultural implements.
  • the disc harrow according to the invention can also be operated in conjunction with a sliding tractor as a windscreen harrow. This was previously not possible with the known disc harrows, because they did not allow a straight-ahead barrel.
  • the harrow is associated with preceding support wheels. These support wheels are height adjustable. They ensure an exact, uniform working depth. They are preferably self-steering by pulling the wheel.

  • With a windscreen harrow the pressure effect of the moving tractor on the windscreen harrow is decisive.
