The invention is an agricultural tillage implement. It is suitable for both sand - pebble loam soil processing, and soil structure under no damaging effect (dust formation, compression .... etc.) is changed.

The milling cutter types known up to now require cohesive soils a very high horsepower, so they are not on these floors Economical enough. In dry soils, the formation of dust is too great, in sandy soils a rapid wear and tear takes place and with With today's knife types, there is a risk of deformation when working on cohesive soils. On the code structure via the L and J-shaped work elements have a harmful effect. The rotation of the work elements causes a compaction of the lower floor barracks, something of agro-technical inspection points is very unfavorable from the point of view, because the soil water and precipitation can no longer penetrate quickly enough and remains that way it on the surface and causes waterlogging and soil erosion.

The aim of my invention is such a new knife system, which avoids the disadvantages mentioned above.

This system is superior to previous ones, both in terms of performance and of all types of milling cutters.

The energy consumption required is low because of the special features Knife profile.

This new knife profile can be used in all known milling machines and build in cultivators.

The age of the elements is long, even after several years of operation they are not used up. This new system can
also replace the work of the plows. With this invention, the disadvantages of the milling machine and cultivator can be avoided and the applicability of the rotary milling machine is expanded. This invention can be used for fruit and vegetable growing, viticulture, forestry and arable farming.
The invention is described with the following schematic representations.

Structure of the cutting elements.

The holder of the individual work elements is on a
closed roller-shaped steel plate (1) bewerkparteiligt. The knife elements (2) are mounted in a helical arrangement on the closed rollers (1) and consist of two steel parts with the unwinding (P,) and unwinding (2).

The components P, unri P "are created by cutting (V,)
brought together, the welding night is partly designed as a cutting edge (C) of hard metal.

Be on the closed roller-shaped steel plate (1) the knife elements (2) attached with welding processes.

Claims (3)

The knives (2) are used up on the closed, roller-shaped steel plate (1) with a deviation (B) of 15 degrees. The declination (D) of the two knives (2) is 6o to the roller. The cutting (C) element has a declination (F} 45 °. If the cutting A - A (Figure II.) Is also the mounting of the rotating part is safe. 1. / Soil milling cutter, cultivator milling system characterized that on a cylinder in equal division and in Schlekonlinien knives with curved profiles and high strength Cutting attachments are attached which are at an angle (C) to the longitudinal axis of the cylinder of Io - 25, advantageously of 15 ° (B) and which are twisted to the cylinder surface So - 6o ° (D), advantageously 6o ° (D) are inclined. 2. / Soil milling cutter, cultivator milling system according to 1 thereby identify, The knife (2) consists of two different curved parts that are used when the two parts are varied A high-strength material is applied, the rotor has a cutting edge with a cutting angle of 4o - 55 ° (F) is. 3. / Soil milling cutter, cultivator milling system according to 1 and 2 thereby identify that the milling cylinder is attached to two axles mounted in the machine structure by means of detachable screw connections is bound. 7415239 11/06/75 Protection claims: 1. / Soil milling cutter, cultivator milling system characterized that on a cylinder in equal division and in Schlekenlinien knives with a curved profile and high strength Cutting edge attachments are attached which are at an angle (C) to the longitudinal axis of the cylinder of Io - 25 °, are advantageously twisted by 15 ° (B) and which are twisted to the cylinder surface 5o - 6o ° (D), advantageously 6o ° (D) are inclined. 2. / Soil milling cutter, cultivator milling system according to 1 thereby identify, The knife (2) consists of two different curved parts that are used when connecting the two parts A high-strength material application is provided, rotor has a cutting edge with a cutting angle of 4o - 55 ° (F) is. 3. / Soil milling cutter, cultivator milling system according to 1 and 2 thereby identify, that the milling cylinder is attached to two axles mounted in the machine structure by means of detachable screw connections is bound. 7415239 11/06/75 This invention Schütz · * ·, not only the species described here and details ι but also other types and deviations. © ela Tassy
