X Международная студенческая научная конференция Студенческий научный форум - 2018

AGRITECHNICA, the leading trade fair for agricultural machinery, has established itself as the most prominent platform for the introduction of innovations. This innovation leadership is underlined by the AGRITECHNICA Innovation Award, which is handed to the winners at the show every two years.

An independent expert committee appointed by the DLG (German Agricultural Society) determined the winners of the Innovation Award AGRITECHNICA from among 320 approved applications for product innovations, based on stringent criteria.

CEMOS AUTO THRESHING - the autonomous threshing system for CLAAS straw-walker and hybrid combine harvesters

Currently operators have to find out by themselves which settings strike the best balance between the optimum drum speed, the optimum concave gap, the suitable aggressiveness of threshing and the quality of the grain. Some operators find this complexity too difficult to come to terms with, and find setting up the combine a chore. Consequently, very often a combine is not set up perfectly to suit the current harvest conditions.

Cemos Auto Threshing is the first system that sets the tangential threshing system on straw walker and hybrid machines automatically. As such, it makes a significant contribution to optimizing the quality of work and performance. Depending on the strategy entered into the system by the operator, it sets the drum speed and the concave gap for optimum results in the current harvest conditions. The USP of the entire system is the fact that all controllers communicate with each other. For example, the throughput controller operates via a special communication module to control the throughput relative to the threshing controller, as well as the separation and cleaning controllers.

Another module in the system is Auto Threshing, which for the first time completes the enormous complex technical step to implement fully automated threshing. On such a harvester, users no longer need to know which settings they have to make to get the desired results. Instead, they enter the harvesting strategy, which is then used by the auto-learning system to optimize all parameters. This innovative automation technology allows combine harvesters to continuously combine at maximum efficiency.

Stalk Buster

Since the corn borer spread across Germany about 15 years ago, it has become the most notorious pest in silage maize crops in the country. It causes losses in yield and quality, because the cobs do not develop well, and they become infested with Fusaria which may then spread to the following wheat crop. One of the most important methods to fight the pest, along with chemical and biological options, is to chop the maize stubble thoroughly and immediately after the crop is harvested. The Kemper StalkBuster is the first stubble-destroying technology that forms an integral part of a maize header. It is the only machine on the market that destroys all the stubble before it is driven on by the forager or the tractor and trailer. Usually about 30% of the stubble remains intact, and as the corn borer winters inside it, a high percentage of undestroyed. Stubble offers them a haven so they can infest the area again the following year. The corn borer pupates in the stubble in spring and the moth starts infesting the new crop after that.The topper is integrated in the header, is relatively lightweight and has a relatively low power input requirement. This means no extra limitations apply for legal road transport. The Kemper StalkBuster is a technical solution that offers great benefits for users, their productivity and the environment.

The working width on ploughs has increased constantly in recent years. These wider widths, however, leave a Z-shaped ploughing pattern on the headland when the bodies are retracted and the plough is raised. This makes it difficult to plough the headland neatly, while crop residues and volunteers are not properly incorporated, leading to volunteer growth in the following crop.

Kuhn’s “Section control” is an electro-hydraulic control system that uses the hydraulic, non-stop break-back system to control the individual bodies based on GPS positioning data, raising and lowering them automatically. The system leads to an absolutely straight furrow edge were there used to be a “Z”. The straight edge is a boon for the following work, such as headland ploughing, drilling, spreading and spraying, and ensures crop residues are effectively incorporated – an enormous plus for field hygiene.

Overall, the system reduces operator fatigue and takes load off the rear axle, the rear wheels and the couplers. Added to this, it can also varies the number of plough bodies in work to suit individual tractor powers and soil conditions.

Landmaschinen Wienhoff GmbHLevel Tuner

The center of gravity varies greatly on slurry tankers when they are fitted with different applicators of different weights. This also affects the drawbar load. As a result, drawbar load may quickly become negative in empty runs – a fact that has accounted for serious accidents on public roads in the past, where ball hitches worked lose after operators forgot to secure them.

On multi-axle slurry tankers, the LevelTuner automatically alters the air pressure inside the bellows on the front axle, thereby adjusting the pressure relative to the drawbar load that is measured by the drawbar suspension system. This way, the drawbar load is always good and road stability is better. In addition, the system ensures field traction is always sufficient during spreading as the tank is being emptied.

Unlike existing options (for example variable-width axles), this center-of-gravity shifting system operates automatically without operator input.

Lechler GmbHESV Electric Shut-off Valve

The best solution in precision spraying is currently an individual nozzle control system that operates the closely spaced nozzles relative to their current GPS position. Pneumatic valves are technically very difficult to make and require an extra air system on the tractor.

The Lechler ESV (Electric Shut-off Valve) unit comprises a valve, an electric line and a connector for straightforward and fail-safe installation on all regular single- and multi-nozzle holders. The nozzle opens and closes rapidly, and CANbus controlled. Its responsiveness and great application accuracy allows ESV to be easily integrated in smart farming systems, and used on 25 cm sections with uniformly spaced nozzles, for example.

Fitted by connecting the electric lines, ESV offers easy and fast installation. Lechler ESV valves offer reliable and profitable operation and thus great user benefits.

Claas-Vertriebsgesellschaft mbH DeutschlandCEMOS for tractors – operator assist system optimizing tractor/implement set-up

The complexity of a modern tractor can be overwhelming to uninitiated operators. This applies especially when a software menu is not very intuitive to navigate, but rather suits the development requirements of the manufacturer.

Claas CEMOS is an interactive system that offers a user-friendly approach to optimize the setting-up of traditional tractor-implement combinations. The system guides the operator through the settings menu – before and during work – using every-day farming language. The system takes into account both the settings entered by the operator and the settings recommended by the manufacturer. In work, it is constantly working to optimize the current settings of the tractor and the implement. To do that, it makes suggestions to the operator after validating the various options. The operator is free to accept or reject the suggestions in line with the targeted quality of work.

The expertise that is built into CEMOS allows unexperienced operators to utilize the combination to its optimum potential with respect to the quality of work, work rate and fuel efficiency. In addition, the system is ready to plug into future automated-and-assist systems.
