Description

1
"LOAD AND UNLOAD SYSTEM APPLIED TO THE DOUBLE FLOW CONVEYOR"
[0001] The current invention is consisting of an innovative system utilized in
the
transportation, load and unload of grains, fruits or seeds for silos of
storage,
dryers and industrial units, providing attributes that enlarge the
possibilities of load
and unload of the products utilizing the same conveyor.
[0002] At present, the transporting systems of grains and fruits in more
efficient
silos, like the conveyors of circular section or drag chain conveyors of
square or
rectangular section, generally act in closed circuit or cyclic in an only
sense among
the bases, walls and height of the silos presenting, in strategic points of
the
assembly, loading places and unload openings of the bulk products. Then, the
other
systems consist in jugs elevators, transporting threads and conveyor belts,
being
able to operate together or independent, varying to each disposition utilized
or to
each need of the rural or industrial producer.
[0003] Those types of conveyors are employed to displace the agricultural
products
from trucks toward the interior of the silos, transportation of the products
from one
silo to another, conduction for bagging, among others processes, always
needing a point of load and another for unload to produce such a movement.
[0004] The difficulty found in the conveyors, without distinction, consists of
the
limitation of the points of load and unload, restricted along the diversity of
products to be moved, that is to say, during the transportation or movement of
a
type of agricultural product, the conveyors do not offer possibilities that a
second
product is displaced or transported simultaneously without contact with the
first
one, having to obligatorily wait to the end of the first proceeding so that it
is
possible to initiate a new procedure.
[0005] The following proposal presents an innovative version in the
transportation
of agricultural products and industries, seeking to soften and to expand
points of
load, transportation and unload of bulk products, returning to the efficient

DETAILED DESCRIPTION OF THE INVENTION
[0015] The system of load and unload applied to the conveyor with double flow
4
offers diverse forms of installation, in this case, as an illustrative example
only, the
disposition can be installed directly in the vertical silos 1 and 2 (FIG. 1)
or adapted
in other conventional principles of transportation of grains, fruits or seeds
3 (FIG. 2),
like conveyors of circular section (PI0301803-2 and MU8801337-5), drag chain
conveyors or any type of conveyor that allows the cluster of the double system
of
transportation. The ornamental representation of the pointed arrows refers to
the
entrance and exit of various products that always accompany the sense of
movement of the conveyors (represented by dark arrows).
[0016] The structural configuration of the loading and unloading system
applied to the conveyor with double flow includes direction changes limits 5
and 6 (FIGS. 3 and 4) of the chain 11 with draggers 12 which are generally
established in the extremities of the assembly, wherein said limit of
direction
change 5 compounds by gears, which is moved 7 and loading point 9 of the
bulk products, and the limit of direction change 6 provided with gear which
moves the system 8 and unloading point 10 of bulk products. The function of
the direction change limits consists on the movement of the chain with
draggers integrated in a cyclic process, enabling the entrance, the exit or
the
displacement of the products of one point to another, according to the need
of the process.
[0017] Due to the double flow of the conveyor, a specific type of hopper was
developed for reception of products directly on the secondary pipe 16 of the
equipment (FIGS. 5, 6 and 7) looking at to expand the odds of utilization of
the
circuit so that it is possible to transport more than one product
simultaneously
utilizing the same conveyor. The loading hopper 13 is made up of upper opening
14,
CA 2771515 2017-07-10

4
top tube opening 15 provided with plate shaped in "V" inverted 18 in its outer
wall
and the secondary tube interval 16 featuring channel 17 for the product enter
in
bulk.
[0018] The loading hopper 13, indicated in the FIGS. 5, 6 and 7, can be
installed
instead of the system that better complies the needs of the process without
being limited in barely one hopper. Its principle begins with the entrance of
the
product by the upper opening 14 of the apparatus through the conveyors with
circular section or drag chain conveyors with square or rectangular section,
transferring the product launched by the sides of the interval of the upper
pipe
15 (indicated in the arrows) until reaching the interval of the secondary pipe
16
provided by a channel in its upper part 17, from where the product enters and
continues its path to the next point of unload. Also it is presented a plate
shaped
in "V" inverted 18 in the external wall of the interval of the upper pipe 15
as a way
to avoid the wear by abrasion of the pipe and to elevate the inclination of
the wall,
guaranteeing a total unload without occurring a stop or accumulation of
products in
the high part of the pipe, eliminating thus possible residues.
[0019] For reception of products directly in the upper pipe 15, a conventional
hopper is employed 19 that does not wrap the secondary pipe (indicated in the
FIGS. 1 and 2).
[0020] Beyond the loading hopper 13, it was likewise developed the double
unload
system 20 (FIG. 8) that interconnects other intervals of both pipes 15 and 16
to an
unload mouth 21 optionally adapted directly in the silos, in a second conveyor
of
circular section or drag chain conveyor with square or rectangular section 3
of bulk
shipment, or even in an industrial equipment. The double discharge system 20
is
composed of plates in form of drawers or sluices 22 and 22.1 arranged on the
lower periphery of both intervals of the tubes 15 and 16, moved by the rack-
and-
pinion method 23 and 23.1 and gears 24 and 24.1, passages or channels 25 and
25.1 directly produced in the intervals of the tubes 15 and 16 and a plate
shaped
in "V" inverted 18 bound on the outside section of the secondary pipe interval
16.

The quantity of double unload systems in the conveyor does not present
limitations, being able to vary according to the need of the project.
[0021] The working procedure of the double unload system 20, illustrated in
FIG. 9,
occurs when is necessary the transfer or unloads of some type of product
without
limiting the process of other products, that is to say, during the
transportation of
certain grain or seed in the secondary pipe 16 (indicated in the arrows), it
is
possible to unload another type of grain transported in the upper pipe 15
impeding the contact of both products or vice-versa (FIG. 10), taking
advantage
of the same system of chain with conveyor draggers for various possibilities
of
employment, seeking to soften the system as an all.
[0022] Internally, the double unload system 20 (FIG. 11) counts with plates in
the
shape of drawers or floodgates 22 arranged in the lower periphery of both
intervals
of the pipes 15 and 16, acquiring movement through a rack-and-pinion 23 and
gears
24 connected with the principle of pulleys and known electric motors. The
function
of the floodgates 22 is to free the product for unload and to control its flow
through
the adjustment of the opening of the conducts or channels 25 produced directly
in
the intervals of the pipes 15 and 16. In the external upper section of the
interval of
the secondary pipe 16 it is introduced likewise a plate shaped in "V" inverted
18
(indicated in the FIG. 9 and in detail in the FIG. 12 with an identical
function of the
plate shaped in "V" inverted related to the hopper 13, avoiding the wear of
the
pipe and improving the unload of the products. Upon arising the need of unload
the grains, fruits or seeds transported in the upper pipe 15, its floodgate 22
is
driven, causing the product to flow through outer side of the secondary tube's
interval 16, exactly on the surface of the plate shaped in "V" inverted 18
linked
(indicated in the arrows of the FIG. 12) until reaching the mouth of unload 21
responsible for directing the product for storage or charge. During this
process, a
second different product can continue through the secondary pipe 16 for
storage
or any another end. Ina contrary situation, the contained product in the upper
pipe
15 continues toward its destiny, as soon as the product of the interior of the
secondary pipe 16 is drained toward the mouth of unload 21 (in the FIG. 13)

through the operation and opening of its above-mentioned floodgate.
[0023] The main components belonging to the double flow transportation system,
as the limit of change direction that move the system 6, the loading hopper 13
and
double unload 20, still allow independent transportation on the conveyors of
the
circular section or drag chain conveyor with the square or rectangular section
3,
preferentially to the MU8801337-5 (FIGS. 14 and 15) through simple adapta-
tions. In this particular case, it uses the direction change edge 6 provided
with gear 8,
which moves the system, and unloading point 10 as purely illustrative example,
but
depending on the design to be developed, it is possible to use the threshold
change
of direction 5 composed of gear 7, which is moved, and loading point 9, to
ease the
equipment application possibilities and meet the specific needs of each user.
[0024] Of this conclusive form, the advantages related to this configuration
related to the conventional systems of agri-cultural transportation determine
the
load points increase and unload of the products reducing the busy time with
move-ments, loads or unload, enabling the process of two or more types of
different products in the same system without risks of contamination or mixes
of
such products and its installation does not require large adaptations to the
usual
conveyors, transforming this invention in a highly influential instrument for
the
agricultural segment.
