Abstract

The Parallelogramsäscharanlenkungen used in the seeding technique have different coulter pressures and deflection characteristics, which can lead to blockages of the coulter bar in difficult ground conditions. The new KLW Hybrid Schar should increase the service life, increase the coulter pressure range downwards and improve the release angle and thus the self-cleaning. To improve the parallelogram array in the direction, the upper rocker of the parallelogram has been provided with a split rocker (3, 12) and a lockable (13) pivot (14). This change allows operating in 2 states the crowd. The first is as a normal high pressure parallelogram saechar for dry sowing conditions. If it comes to problems due to moisture, the lock can be removed and the coulter runs with less coulter pressure and with a different angle in the ground, so that a clogging of the coulter bar is omitted. The KLW Hybrid seed coulter is suitable for all common parallelogram scrubbers on the market and increases the operating times and the operational safety of the seed drills.

Description

The invention relates to a coulter suspension for agricultural coulters in the form of a lockable three-arm swing in both a rigid and mobile state, umzeugzeuglos convertible, can be driven.

State of the art:

In agricultural engineering, coulters are working on a single-arm swingarm 1 or on a two-arm swing also parallelogram crowd 3 called used. These pulled coulters ( 1 Pos 6 ) are on the arms (pos 3 ) and are by means of springs, rubber or Silentblöcke / bellows, air pressure or hydraulic (pos 5 ) so that the crowd is pulled or pushed into the ground. Please refer 1 ,

Also describes the crowd (pos 6 ) when triggering a radius and the pressure roller (pos 7 ) dodges upwards. Please refer 2

When dodging an obstacle, the position to the neighboring flock changes significantly with a radius. This gives a better self-cleaning of the coulter.

One-arm swing is pulled or pressure loaded in the 1 with the numbered positions 1 Bracket; 2 Pivot point; 3 rocker; 4 Pivot point; 5 Feather; 6 Disc Plow; 7 Depth control wheel; 8th Schar camp; 9 Roller bearings; 10 Floor top edge; 11 deposited seed; 12 Foreign body shown. 2 shows the Einarmschwinge by a foreign body upwards in the radius of the articulation point evasive.

The designations correspond to the 1 ,

On the droves with a two-arm swing / parallelogram rocker 3 there is a lower (pos 2 ) and upper rocker (pos 3 ) on the Schararm. The group gives way in severe conditions or foreign bodies ( 4 ) only upwards and does not describe a radius. For heavy soils self-cleaning is low. The smaller the row spacing the lower the self-cleaning of the coulters and thus an increased risk of clogging.

Task:

Both types of wings on the droves whether tow or disc coulters have conditions that are advantageous for field safety. But it is not yet possible to use them together in the field.

The invention aims to improve the safety of use and to place the seed according to the appropriate conditions in the soil

This goal of achieving 2 states is possible by adding an additional rocker to the upper or lower rocker / arm. If the 3 rocker with the second rocker rigid, that both act as a rocker, the crowd is equipped with a parallelogram. As a result, it has the same properties as a parallelogram crowd. Exact depth control, high coulter pressure, parallel excavation.

When the 3 arm is released (either through a pivot point in the rocker arm or a telescoping strut), the squad changes from a parallelogram / 2 arm swing arm to a three arm swing arm with a special release characteristic. This increases the deflection of the share and ensures operational safety without clogging of the seed rail. Reduced coulter pressure, avoiding radius, increase self-cleaning

5 Rigid state Parallelogrammschar with locked 3 arm / rocker (Pos 12 ). Pivot point (pos 14 ) with the bolt (pos 13 ) arrested. The spring or other pressure load can also be attached to the rear as in the normal parallelogram suspension.

9 Triggered telescopic spring

It is possible to install all variants as far as possible. Variable telescopic swingarm integrated below or above. The printing mechanism for the coulter pressure is also possible in several positions.

The changes in the linkage also change the coulter pressure and the tripping characteristic.

With a movable third swingarm, the flock follows a radius when encountering an obstacle and the coulter pressure can be shifted down to a range of 10-15 kilograms of deployment force.

The radius that describes the crowd when triggering brings solid earth out of the rail and thus leads to a better self-cleaning. Clogging is thus reduced.

With the rigidly mounted third swingarm, the crowd is a parallelogram crowd and can transfer more forces to the ground. The evasion takes place only by lifting almost vertically upwards. No radius is traversed. The depth guide and pinch roller can re-solidify the soil to a maximum in dry conditions.

Through these two states, the crowd can be adapted to the circumstances.

Drawn pack with movable third swingarm up or down for:
Wet conditions less coulter pressure, radius when triggered by an obstacle releases the adhering earth and the coulter bar does not close.

Drawn parallelogram with rigid third swingarm for:
Dry conditions with high coulter pressure, good depth and fast working speed.

Claims (1)

Agricultural coulter holder with a single-arm swing arm / Hebelarmführung or a two-arm swing / parallelogram guide to place the seed in the ground are state of the art. This starting point is known. The invention is now characterized in that by the new design of a coulter suspension with 3 wings as described below, new black states can be realized. If the third built-in swingarm is locked, you get back to the swing arm suspension / parallelogram suspension. There will be both suspension types two-arm swing and three-arm swing in the field and use. This is done without tools on site. With this technical new development, the complete kinematics of the coulters changes and a wider range of coulter pressures is available. Especially the avoidance of the coulters upwards over an obstacle is facilitated by the fulcrum of the 3 rocker. The deflection angle of the coulters in foreign bodies and in humid conditions changes and the self-cleaning of the coulters is increased. This results in a higher operational safety of the seed drills and the range of applications is increased.
