Abstract

Meters for fertilizers, small seeds, and chemicals include a housing defining a loading chamber, a rotatable metering disk provided with a receiving surface and a discharge surface, the disk including metering orifices; a ring including a discharge opening, and an insulating barrier arranged in the interior of the housing, the insulation barrier forming an insulating chamber on the rotatable disk and defining an inlet region of the disk and an output region of the disk; a metering bulkhead associated with the insulating barrier in the inlet region of the rotating disk with metering orifices loaded, the metering bulkhead being arranged on the rotatable metering disk so that a lower portion of the metering bulkhead is coplanar to the receiving surface of the rotatable disk.

What is claimed is: 
     
         1 . A maintenance system for a meter for fertilizers, small seeds, and chemical products, comprising:
 a housing defined by a base, a side wall portion, and an upper inlet portion, the housing defining a loading chamber;   a counterbase positioned below the housing by at least one fixation mechanism; and   at least one closure mechanism configured to block passage of material into the loading chamber.   
     
     
         2 . The maintenance system of  claim 1 , wherein the fixation mechanism comprises:
 two ears comprising oblong apertures arranged in a housing;   at least one shoulder in the counterbase comprising an aperture; and   a rod passing through the apertures of the ears and the aperture of the at least one shoulder.   
     
     
         3 . The maintenance system of  claim 1 , wherein the at least one closure mechanism comprises at least one moving plate.
