3.4 REGULATIONS
3.4.1 DOSER (Fig. 20)
The volumetric distributing device, GRINTA, is essentially
composed of three elements for seeds distribution:
A) aluminium monobloc frame;
B) agitator element;
C) dosing rollers.
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 can be disabled by simply removing the drive belt.
To disable the agitator, lift the round belt above the edge of the
drive pulley and, on the opposite side, rotate the dosing roller in
the driving direction. The belt will come off (Fig. 21).
(To fit the belt, see chapter on dosing roller)
DOSING ROLLERS
- Large diameter to reduce the number of revolutions and avoid
fertilizer load losses;
- High number of cells arranged in a steggered pattern to
guarantee uninterrupted delivery;
Assembling and disassembling the dosing roller
All the dosing rollers are compact units constructed in a single
block (except for the fine seeds dosing roller, yellow).
Never fit dosing rollers with screws loosening the handwheel!
The radial precision of the wheels, which are calibrated after
assembly, could be damaged!
Always use gloves: after calibration, the new dosing rollers
could have sharp edges that might injure the operator!
There are various types of wheels for a wide range of applications,
in three different product families (Fig. 22):
D) 2 elements, 8 chambers per wheel, (mod. G1002) distribution
of fertilizer;
E) 5 elements, 8 chambers per wheel, (mod. G1000) distribution
of seeds;
F) 5 elements, 32 chambers per wheel, (fine seeds dosing
roller) (mod. F25-125).
Use a suitable metering roller with the type of distributed seeds.
When the machine is completely empty...
1) Remove the belt from the agitator and fully disconnect the
metering roller transmission (Fig. 21).
2) Take out the bearing support of the metering roller (G, Fig. 23),
3) Take the metering roller out sideways (H, Fig. 23)....
To re-assemble, follow the steps in reverse order.
