The JÄGER Group has developed improved interchangeable rubber inserts for the automatic dosing unit. In the unit, the seeds are correctly dosed via rotors. The individual rotors have the same internal structure, via which the connection to the drive shaft is made. On the outside they are adapted to the respective seed in size and shape, which makes it easy to change the inserts. Contractors and farmers need this quick exchange on site so that the machines can be retrofitted for different purposes and service life is kept low.
Together with the seed drill manufacturers, we develop the metering wheels in such a way that they meet the respective chemical and climatic requirements. Sowing at ten degrees outside temperature may require a different rubber compound than sowing in a hot environment. The rubber can be adapted by selecting the compound. Here we can draw on our wealth of knowledge from product development with rubber and plastic. The JÄGER Group has sophisticated test methods and test procedures at its disposal to determine the right rubber compound for the application.
The seed is usually supplied with a suitable fertilizer addition, the fertilizing of the sowing is thus completed. When selecting the material, we pay particular attention to ensuring that the chemically aggressive fertiliser used is neutral in relation to the polymer mixture used in the rotors. Further important criteria of our customers are the abrasion resistance of the mixture as well as durability in agricultural use. Here you benefit from our many years of experience in compound development and optimisation!
