9.9 - Depth adjustment and seed cover.
The seed depth placement in the soil is determined by the back press
wheel (“a”Fig.020) through drilled sheet “b” of an exclusive design and of the
locking pin “c”. The locking pin placement
in a determined hole is what will determine
as the wheel can arise, lowering in this way
the set of the double disc. So, as more high
the pin be placed higher will be depth and
the more below the pin be placed, smaller
will be the depth. There are two vertical lines
of holes for your reference. The holes in the
same line are distanced about 1, 0 cm (a
centimeter). However as the lines are offset
among a hole and another of a line for other,
the distance is of 0, 5 cm. (half centimeter),
what will allow to regulate the depth with a
lot of precision. However, should check in the field, opening the furrow, the
real depth, the one that the seeds are placed.
The seed cover is made by tow covering discs “a” (FIG.021) that are
placed at the both sides. The contact angle of these discs can be regulated
and so altering the quantity of earth that is placed above the seed. For that
it is just being enough to alleviate the screws “b” and to modify the position
of the discs. If we decrease the space among them, higher quantity of earth
will be placed on the seed and it
happen the inverse if we increase
the distance among them.
