 In less than two weeks the world’s largest ag machinery show opens its exhibit halls. In preview of the show, the Agritechnica organizers have awarded their innovation awards including these four gold medals:

AirSep pneumatic impurities separator for potato harvest, manufactured by Grimme, Damme, Germany

GRIMME Stationaere Anlage mit AirSep

In potato harvesting the systems used for separating impurities such as stones and dirt clods are predominantly mechanical. However, these are limited in performance efficiency, and especially with multiple-row harvesting machinery frequently represent a bottleneck. By combining a perforated conveyor base and an uplift airstream flowing through from below, a pneumatic separator device in which the direction of crop flow and hence the machine-specific potato throughput are retained without restrictions. During the passage through the separation area the tubers are virtually kept gently floating above the vibrating conveyor base, while the heavier stones and clods drop down and are passed via a segmented lock to a removal belt. The quality and performance of separation can be adjusted from the tractor to the composition of the material being harvested by altering the combination of air flow rate and the inclination and frequency of the conveyor base.

 

AXMAT: Automatic spreading pattern adjustment of a twin disc fertilizer spreader, manufactured by
RAUCH, Sinzheim, Germany and MSO Measuring and Positioning, Bad Münstereifel, Germany.

RAUCH AXMAT

With AXMAT, Rauch presents the world's first solution featuring automatic online measuring of fertilizer distribution and automatic adjustment of a disc fertilizer spreader to the fertilizer type in the tank and the desired working width. For the first time high fertilizer distribution precision is achieved automatically with the aid of microwave sensors and an automatic adjustment system on the fertilizer spreader. An arm swiveling about the distributor disc of a disc fertilizer spreader provided with microwaves records the spread fan position beneath the fertilizer spread fan, without contact, and sets the spread pattern automatically to the desired working width with the aid of the rotatable tank bottom and dosing aperture. During the spreading process, the spreading pattern is monitored permanently and the discharge point of the fertilizer to the distributor disc is readjusted automatically as required. The novel, automatic self-setting of the fertilizer spreader to the required working width makes it possible to achieve higher precision than is otherwise encountered in conventional adjustment practice and achieves this without the need for any spreading test on the field. The permanent self-monitoring of the spread fan also allows automatic online readjustment of the setting system to the set working width in response to changing fertilizer batches or changes in weather conditions.
