3.4 DISTRIBUTION
3.4.1 SEED DISTRIBUTOR
The doser (Fig.23) the most important part for seeder operation,
is located underneath the seed 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.
Thanks to a gearbox (A Fig. 23) it allows the distributor roller (B)
to operate with two gear ratios, by changing the position of the
red toothed wheel (C Fig. 24, 25). In position «N» (Fig. 24), the
gear ratio is 1:1, as imposed by the pair of toothed wheels Z19;
when the wheel (C) is shifted to the «M» (Fig. 25) position, the
distributor wheel halves the number of revolutions, as the drive
is then composed of the red drive wheel Z14 and the drawn
wheel Z28. When a dosing test, as described in chapter 3.4.2, is
performed, it may be observed that the quantity of product
distributed is halved (see Table 5) compared to the test using
ratio 1:1. The position «M» of the toothed wheel (C) is necessary
for the distribution of small seeds and quantities.
The screw rod (D) enables the degree to which the gate opens to
be adjusted depending on the value of the graduated scale,
calculated using the table and the distribution test (chapter 3.4.2).
The reference element for setting the gate valve opening is point
A (Fig. 28).
ATTENTION
Do not close the gate when there are seeds inside the doser:
this would result in the dosing parts being broken.
The locking spring (E Fig. 23) enables the opening range of the
gate to be modified which, in turn, modifies the capacity of the
dosing roller at the same time. The position «E1» (Fig. 26) enables
the gate to be opened on a graduated scale, ranging from 0 to
110, with maximum capacity of the dosing roller; in the «E2»
position, on the other hand, there is a gate opening range of 0 to
25 and the capacity of the roller is reduced. It is important always
to remember to close the gate completely (0 on the graduated
scale) in order to invert the position of the locking spring (E).
ATTENTION
Do not close the gate when there are seeds inside the doser:
this would result in the dosing parts being broken. When
correctly placing the locking spring a click will be heard
indicating that the operation has been completed successfully.
