  ROLLER ROD WITH BAR, FOR TREATMENT APPARATUS

SOIL IN AGRICULTURE

  The invention relates to a bar trimming roller for soil treatment apparatus and

  its combination with equipment for sowing

  planting, manuring and plant protection, comprising a roll wrapper in parallel bars,

  fixed by support discs on the roller axis.

  Bar Rotating Rollers are used in agriculture for surface treatment of the soil after plowing, before seedbed preparation and, increasingly, simultaneously also as an auxiliary element for the combination of apparatus.

Scrolling rollers with bars

  simultaneously working the soil surface for the final

  seedling, which assist the combination of apparatus and should be used for apparatus worn by

  tractors must be light, stable

  high level and should not tend to jam.

  The bar-moving rollers consist of a roll casing, formed of a number of parallel bars, secured by means of

  support discs on the roller axis.

  Other support discs are arranged between the end discs, depending on the length

of the bar trimming roller.

This limits on one hand the defor-

  bars on the stones, but on the other hand increases the stuffing disk. The support discs are as far as possible formed of flat discs, planes, to oppose the stuffing, which nevertheless has

  resulting in limited stability.

  To: achieve high stability,

  it is known to have inside the roll

  2), or fix the intertwined bars against the beams on the support discs (SU certificate of the invention 1 094 585). We also know very large support discs, profiles, but which lead yet again to the stuffing of the

  roller because the penetrating earth adheres to i-iux profiles.

  In order to be able to move further the bearings of the bar ramming roller in the roller body, it is known to

  hollow printed end discs (FR 2 405 628).

  The support of the bars inside the roll is carried out at

  again by flat support discs.

By patent GB 1,600,278,

  connatt a disc harrow the discs are free-

  crossed in the central work area by parallel-axis bars. The disc harrow retains its basic function. It can not be used in the sense of a bar trimming roller. The bars prevent the normal flow of soil from the angled disc harrows, result in high consumption of tensile force and can not be fixed durably

  on disks that are usually soaked.

The invention aims to

  extend the time limit for using the emot-

  rider by increasing its stability.

  The object of the invention is to configure the support discs of the bar-shaped rotary roller and to arrange them so that an increase in stability, in particular of the transverse stability, the cost in material and the weight in front of it is achieved. At the same time, lowering and jams

still reduced.

  According to the invention, this is achieved in that all the support discs and the end discs, characterized in that all the support discs and the end discs are in the form of a hollow disc and disposed on the roll axis so that their hollow faces, starting at the center of the roll axis, are oriented outwards,

  in plane symmetry towards the roller bearings.

The roller bearings are dis-

  placed inside the hollow space of the end discs. To save weight, the support discs and end discs are provided with passages inside the disc opening.

  and / or recesses on the edge area.

  By this embodiment and this arrangement of the support discs has been found a simple and effective solution increasing the stability of the bar-shaped rotary roller, limiting the weight, reducing jams even for wet soils, and susceptible

  to be manufactured for a reduced cost.

  The hollow discs exhibit considerable resistance, in particular to the transverse displacement of the roll, and it is true in both directions. Hollow dicks may be of a lower material than flat discs and the same stability can also be obtained with fewer discs. Remnants of soil can barely adhere to the libse hollow disk, so there is no need to rely heavily on jams, as they are known to rely on jams, such as two known with cross rollers or transversely using profiled support discs. The increase in transverse stability also allows the limitation of the number of bars, so that other material savings and jam limitation can be achieved. The fact of housing the roller bearings in the hollow disc allows a compact alignment, next to each other, of bar-shaped rotary rollers, so that

  that can not appear any band not worked.
