DEVELOPMENTS FOR QUIETER
AND FASTER HARVESTING
Modern combine harvesters are the giants of agriculture. At harvest time they are in continuous operation and ensure that grain, corn, rape and other field crops can be harvested efficiently. To do this, the combine separates the valuable grain from the stalks fully automatically and in several integrated operations.
In the development of combine harvesters, the goal of efficient harvesting is paramount. Due to the given dependency on the weather, certain time windows arise which must be used intensively, especially during the harvesting season. Current combine harvesters can weigh over 30 tonnes and achieve a working width of over twelve metres, which significantly increases harvesting performance. A considerable increase in efficiency has been achieved by increasing the cutting width. Nevertheless, the question remains open as to whether there are any technical innovations in combine harvesters and forage harvesters in addition to changes in size.
In the prototype development of combine harvesters, the replacement of the materials used in the machine opens up a lot of unused potential. New thinking in material selection and the replacement of entire modules or components lead to many advantages:
Durability and durability of components and modules reduce the risk of failure and make harvesting more predictable.
For the various work steps, the harvested crop must be transported in the combine harvester. “Silentium Drive”, the new innovative conveyor system for combine harvester feeder channels with rubber fabric belts and cam drive eliminates one of the main sources of noise in the combine – the unpleasantly loud clashing of chain and box-shaped conveyor shaft, which is commonplace in conventionally equipped combines, has come to an end thanks to our innovation. The Silentium Drive system can be installed in any combine harvester.
There is much more potential in combine harvesters for optimisation through appropriate material selection. Our companies Broekema, Artemis and Jäger Gummi und Kunststoff presented a new solution for the elevator in the grain tank area at Agritechnica 2017. A rubber belt with high-strength reinforcing inserts and very low elongation replaces the previously used steel chain when transporting the grain into the grain tank. This has made higher speeds and increased throughput possible. Thanks to the synchronous properties of the system, more than 30 kW of power can also be transmitted with this belt solution to downstream units such as distribution augers in the grain tank.
Engineers from various agricultural machinery manufacturers work every day to optimise their machines for the various applications and climatic conditions. As experts in the use of rubber and plastics, we actively support development projects within the framework of development partnerships. Individual development and the development of prototypes for combine harvesters is the rule here. We start product optimisations or new developments as a joint project and lead them to success together with you!
Our newly developed components and modules made of rubber or plastic for combine harvesters are clearly superior to the previously used steel solutions in terms of durability and flexibility. Often the respective component is completely redesigned according to the current requirements of the industry.
The reliability of the machines is ensured by the assemblies we have developed through high abrasion resistance as well as durability.
For this purpose, the JÄGER Group develops individual prototypes together with the combine harvester manufacturers. Within the scope of field tests, these pre-series models prove under the usual harvesting conditions that they are clearly superior to the combine harvesters used so far. We regularly analyse how the new components and modules perform in direct comparison with the previous versions. In the practical tests, the laboratory results of the material testing are validated once again under typical operating conditions.
Our holistic development approach includes the entire life cycle of products, modules and components. This also includes the availability of spare parts and the replacement time of assemblies. Even the installation and assembly of spare parts are tested and evaluated. A lot of time can be saved here by developing installation sets with a well thought-out combination of individual parts.
