3.4 DOSER
The doser (Fig. 7) the most important part for distribution, is
located underneath the fertilizer hopper.
Motive power is transmitted to it by the drive wheel through
gears (with ratios proportional to the width of the work to be
carried out) and chains.
The Electric Distribution Control can be supplied as an
accessory. In that event, for the metering operation and the
metering adjustment, checking and tests, please refer to the
relevant User and Maintenance Booklet.
The volumetric distributing device, GRINTA, is essentially
composed of four elements for ferilizer distribution:
A) aluminium monobloc frame;
B) agitator element;
C) dosing rollers;
D) Feeler pin.
MONOBLOC FRAME
The monobloc frame is made of aluminium and offers the following main advantages:
- realization of very high precision and high quality over time;
- resistance to the effects of UV rays or to the problems of harsh autside temperatures;
- high resistance to corrosion;
- quick simple maintenance: in a few minutes we can completely remove the components of the doser without fully unscrewing the
screws, using just one spanner.
AGITATOR ELEMENT
Guarantee of continuous feeding to the dosing rollers.
The agitator has a diameter of 85 mm and consists of 4 elements (curved pins). If the agitator is running too fast, its mixing effect can
be halved, by removing the two center pins (B, Fig. 7).
The agitator can be disabled by simply removing the drive belt.
- To disable the agitator, lift the round belt above the edge of the drive pulley (Fig. 8) and, on the opposite side, rotate the dosing roller
in the driving direction.
- Simply leave the belt on the drive shaft (Fig. 9).
(To fit the belt, see chapter on dosing roller)
