Description
CA 02203478 1997-0~-20 "AN IRRIGATING SPRINKLING MACNINE n I . Background of the art The present invention relates to an irrigating sprinkling machine by means of which a large piece of land can be irrigated; characterized in that - apart from being relatively light - it can be folded and adapted according to the wind.
As it is known, one of the main objectives of the irrigation of crops is to provide the soil with the level of humidity that the soil has not got from rainfalls.
One of the best systems to irrigate is through sprinkling, by means of revolving sprinklers and pipes or tubes comprising a plurality of small holes, expelling the water which waters the soil like rainfall.
Related art There are many machines and devices used for sprinkling.
One of them comprises a cart or carriage on which there is assembled a revolving sprinkler tube connected to a hose which is on a rolling drum which in turn is assembled on its own portable chassis.
It works as follows: the cart moves away from the rolling drum as the hose unwinds. Then, as water flows, the sprinkler tube expels water covering a certain area, and thus covers a semicircular piece of land. Meanwhile, a hydraulic CA 02203478 1997-0~-20 turbine, makes the sprinkler tube go back towards the drum, around which the hose winds until irrigation is over.
This conventional device is effective in one aspect, but at the same time it embodies a number of drawbacks, such as the following:
* it comprises only one water expelling source, so should some malfunctioning or fault occur in the sprinkler tube all the irrigation process will become difficult.
* if the ground happens to be rough or hilly the movement of the sprinkler tube may either be stopped or blocked, and therefore, so may the direction and maximum distance of the jet.
* the wind effect, which in the case of these systems affects irrigation. Though orienting means have been included, the variations of the winds still affect the performance of the system.
Another well-known irrigation device is a long watering duct, which forms a series of arcs comprising structural reinforcement, which at least in the joints, have a supporting base with a wheeled gear. The set of these carts/carriages enables the whole device to move, so that it either rotates around one of its ends, or it moves straight ahead.
In this case, irrigation is accomplished successfully, but said device is complex and expensive, and CA 02203478 1997-0~-20 above all, it is very heavy. Therefore, it is difficult to move along some kinds of ground, and it is difficult to store.
Moreover, said structure needs engines to drive both the tower and the cart/carriage.
In brief, this is a highly expensive device which does not solve all the operation drawbacks.
But, the irrigating machine of the present invention overcomes all the limitations and drawbacks of the irrigation systems known in the art. It comprises two watering wings that support the watering ducts. Each of these wings, which extend from one of the sides of the cart, comprises a meshed structure/framework of blocks joined by hinges or joints.
Both long wings are supported by a main tower by means of a plurality of arms that shape triangular supports that secure the resistance of the structure, and support the set by means of main and secondary reins. In this way, the structure becomes significantly light and balanced, and does not require wheels or additional supporting carts.
One of the most important aspects is the relationship among the joined blocks, and the many reins that enable the wings to move even when winds are strong; and among said blocks there are washers o stretching means acting as separators.
CA 02203478 1997-0~-20 Furthermore, because of its features, this machine can be placed in a fixed location, and can cover a large piece of land, which reduces operative costs.
Finally, it should be underlined that the whole set of this machine is not sophisticated at all; for this reason it can be produced at a very low cost.

CA 02203478 1997-0~-20 III. Main objective AN IRRIGATING SPRINKLING MACHINE of the kind intended for irrigating a large area, comprising: a supporting structure (3) assembled on a tractor (t), a rotating drum (a), for winding a hose (4), which on the one hand is connected to a water supply (4") and on the other hand is connected to sprinkling ducts (4') of the machine, comprising sprinkling nozzles which can be oriented towards the soil; characterized in that said sprinkling ducts (4') are assembled along two wings (c) and (c'), which are joined in relation to tractor (t) against which they can be folded, and are projected from the sides of said tractor (t); each of wings (c) and (c') is a meshed triangular bar structure (12), that forms a long arm which is the support of said sprinkling ducts (4'), and comprises blocks (12') joined by joining means (9), and is supported form the top by the vertexes of supporting arms (8) in a triangular arrangement which in turn is stretched by main reins (11), and stabilizing reins (13) and secondary reins (13'); said main reins (11) are stretched form top (6) of tower (b) built on said tractor (t).
IV. Description In general terms, the irrigating sprinkling machine comprises a device for the irrigation of a large piece of land. For this reason it comprises a supporting structure (3) CA 02203478 1997-0~-20 which can be assembled either on a tractor (t) [figure 1], or on a cart with wheels, drawn by the tractor [embodiment of figure 10]. On said structure (3) of the embodiment represented in figure 1, there is a main tower (b), and at the sides of the tractor there are two irrigating wings (c) and (c') on which there are sprinkling ducts (4'). The latter are connected to a hose (4) wound around a rolling drum (a)., which continues in a hose or rigid duct assembled on irrigating wings (c) and (c').
In the embodiment shown in figure 10, the main tower is identified as (b'), the main bars of the tower as (5'), and the stretchers as (6"').
From now on, for the sake of brevity, reference will be made to the assembling shown in figure 1. It should be taken for granted that said assembling is equal to the one shown in figure 10, except for the fact that in the latter the device forms a cart, instead of being assembled directly on tractor (t).
More particularly, water supply (4") is connected to a rolling duct (4) rolled in a groove (1) of the rotating drum (a) . The latter can rotate around its own axis (2) which is assembled on structure (3) of tractor (t).
The other end of water duct (4) is connected to sprinkling ducts (4') comprising sprinkling nozzles (10) oriented to the soil.
CA 02203478 1997-0~-20 Said sprinkling ducts (4') comprise a plurality of sprinkling nozzles (10) arranged along two joint irrigating wings (c) and (c'), each of which projects from its corresponding side of tractor (t), against which they fold.
Then tightness of the cables that support said watering or irrigating wings (c) and (c') is achieved by means of a winch (m) or similar, represented schematically in figure 2.
Each of these wings (c) and (c') comprises a triangular meshed structure (12) - especially as shown in figure 9 - which comprises blocks (12') jointly related by means of joints (9), such as shown schematically in figure 8.
In said figure 8, two blocks of structure (12) are shown which correspond to the same wing (c), from which terminal complementary and punched pieces (15) are projected.
Said pieces are linked to an axis (16) which performs as a braking link, and a rubber washer (14) is inserted which performs as a shock absorber (figure 8).
It is noted that the way joint (9) is built is not relevant; it could also be a bolt, projected from one of the blocks (not shown), which fits loosely inside the other, plus the use of said rubber washer (14) acting both as a separator and shock absorber.
The link between both pipes is achieved by means of the tightness of the reins, driven from winch (m), whereas there are terminal caps which serve as the beginning of said CA 02203478 1997-0~-20 bolt and also as insertion means of said bolt, and are wide enough to limit the folding of the structure, therefore performing as stops; in this case, the lower reins and the supports indicated as (8'), (12') and (13") in figure 7.
In this way, each wing (c) and (c') forms a long arm that is a support for the sprinkling ducts (4) , together with their nozzles (10) [figures 1, 2, 3, 6, 7 and 9].
Moreover, part of blocks (12') of the structure (12) can have any appropriate resistant shape, such as in the case of supporting arms (8), arranged in a triangular fashion, whose low vertex is in one of the ends of each block (12).
From the top vertexes of the arms there is a pair of converging low secondary reins (13') which end clamped to the low vertex of the next triangular support (8), arranged in such a way that they converge towards the free end of the corresponding irrigating arm (c) and (c').
Also from the top vertexes of the triangular support of arms (8), there is another pair of stabilizing reins (13). In this case, said reins (13) cross to finally get clamped the top vertexes.
The clamping of the set is complemented by means of two main reins (11) - which link the two top aligned vertexes of all the triangular supports (8) of each wing (c) and (c')- and finally get clamped by means of the CA 02203478 1997-0~-20 corresponding stretching bars (6') to the top ends (6) of bars (5) of main tower (b).
Supporting arms (8) end in latches (8') which hold on to a top crossbar (figure 11), and get latched to a sleeve (17') which is rotatably assembled on a crossbar (17) provided by the triangular frame of the winds (c), [figures 4 and 11]. In this way, once said arms are unlatched, they fold once again such as shown in figure 11, so that the system gets smaller and folds completely for storage.
Also, in order to put up bars (5) of the main tower (b), the device can comprise a winch (not shown) which tightens o loosens the supporting or stabilizing cables, o preferably, hydraulic arms as those illustrated schematically in figure 1 on the same device; said hydraulic means comprise hydraulic devices whose plunger projects outside of the cylinder together with a rod or shank joint to the bars of said main tower so that depending on the driving force said rod or shank projects more or less, thus enabling the complete building of the main tower (b), or partial building of main tower (b) (in case of strong winds).
In another embodiment, the irrigating wings (c) and (c') comprise complementary triangular detachable supports (8') held by means of corresponding lower reins (13") and arranged in the opposite lower part of main supports (8) [see figure 7J.
CA 02203478 1997-0~-20 As for the frame itself of the corresponding blocks of each wing (c) and (c'), it can be a resistant triangular structure of blocks (12) or (12') as shown in detail in figure 9, in which each lower pipe (4) is, as shown, the rigid duct along which water flows which is connected to the hose described above, and comprises sprinkling nozzles (10) which are in fact the sprinklers, oriented up or down o in the direction the machine moves.
The set works as follows:
When tractor (t) advances, the rolling drum (a) unrolls the hose or flexible pipe, which allows the permanent connection between hose (4) and the wings (c) and (c') with the water supply (4").
Said wings (c) and (c') are perfectly open and balanced because of the connection between main tower (b) and triangular supporting arms (8) and the main and secondary reins (13'), tightening by means of winch (m), or loosening if necessary (even reaching the soil) if necessary because of strong winds.
More particularly, while converging lower secondary reins (13') are affected by the tension because of the corresponding block weight (12') the arms forming triangular supports (8) are affected by compression.
With the arrangement described above, the tensions go directly to main reins (11) tightened in the main tower CA 02203478 1997-0~-20 (b).
Moreover, if the machine is subjected to the action of winds of different intensity, wings (c) and (c') are not rigid (as said above) since the joints (9) enable the partial rotation of blocks (12') which form the meshed structure (12), starting from the final wing block (c)-(c') to continue with the lower block. (as shown in figure 5.) Besides, each of blocks (12') rotates partially , the tightness of said lower secondary reins (13') decreases, blocks (12') diverge, whereas the tightness in those reins (13') decreases. (se figure 4.) Also, there is a certain movement of the arms forming the triangular supports (8) limited by stabilizing reins (13).
Under these conditions and in spite of strong winds, the machine can advance with its wings (c) and (c') in perfect balance.

Said pieces are linked to an axis (16) which performs as a braking link, and a rubber washer (14) is inserted which performs as a shock absorber (figure 8).
It is noted that the way joint (9) is built is not relevant; it could also be a bolt, projected from one of the blocks (not shown), which fits loosely inside the other, plus the use of said rubber washer (14) acting both as a separator and shock absorber.
The link between both pipes is achieved by means of the tightness of the reins, driven from winch (m), whereas there are terminal caps which serve as the beginning of said CA 02203478 1997-0~-20 bolt and also as insertion means of said bolt, and are wide enough to limit the folding of the structure, therefore performing as stops; in this case, the lower reins and the supports indicated as (8'), (12') and (13") in figure 7.
In this way, each wing (c) and (c') forms a long arm that is a support for the sprinkling ducts (4) , together with their nozzles (10) [figures 1, 2, 3, 6, 7 and 9].
Moreover, part of blocks (12') of the structure (12) can have any appropriate resistant shape, such as in the case of supporting arms (8), arranged in a triangular fashion, whose low vertex is in one of the ends of each block (12).
From the top vertexes of the arms there is a pair of converging low secondary reins (13') which end clamped to the low vertex of the next triangular support (8), arranged in such a way that they converge towards the free end of the corresponding irrigating arm (c) and (c').
Also from the top vertexes of the triangular support of arms (8), there is another pair of stabilizing reins (13). In this case, said reins (13) cross to finally get clamped the top vertexes.
The clamping of the set is complemented by means of two main reins (11) - which link the two top aligned vertexes of all the triangular supports (8) of each wing (c) and (c')- and finally get clamped by means of the CA 02203478 1997-0~-20 corresponding stretching bars (6') to the top ends (6) of bars (5) of main tower (b).
Supporting arms (8) end in latches (8') which hold on to a top crossbar (figure 11), and get latched to a sleeve (17') which is rotatably assembled on a crossbar (17) provided by the triangular frame of the winds (c), [figures 4 and 11]. In this way, once said arms are unlatched, they fold once again such as shown in figure 11, so that the system gets smaller and folds completely for storage.
Also, in order to put up bars (5) of the main tower (b), the device can comprise a winch (not shown) which tightens o loosens the supporting or stabilizing cables, o preferably, hydraulic arms as those illustrated schematically in figure 1 on the same device; said hydraulic means comprise hydraulic devices whose plunger projects outside of the cylinder together with a rod or shank joint to the bars of said main tower so that depending on the driving force said rod or shank projects more or less, thus enabling the complete building of the main tower (b), or partial building of main tower (b) (in case of strong winds).
In another embodiment, the irrigating wings (c) and (c') comprise complementary triangular detachable supports (8') held by means of corresponding lower reins (13") and arranged in the opposite lower part of main supports (8) [see figure 7J.
CA 02203478 1997-0~-20 As for the frame itself of the corresponding blocks of each wing (c) and (c'), it can be a resistant triangular structure of blocks (12) or (12') as shown in detail in figure 9, in which each lower pipe (4) is, as shown, the rigid duct along which water flows which is connected to the hose described above, and comprises sprinkling nozzles (10) which are in fact the sprinklers, oriented up or down o in the direction the machine moves.
The set works as follows:
When tractor (t) advances, the rolling drum (a) unrolls the hose or flexible pipe, which allows the permanent connection between hose (4) and the wings (c) and (c') with the water supply (4").
Said wings (c) and (c') are perfectly open and balanced because of the connection between main tower (b) and triangular supporting arms (8) and the main and secondary reins (13'), tightening by means of winch (m), or loosening if necessary (even reaching the soil) if necessary because of strong winds.
More particularly, while converging lower secondary reins (13') are affected by the tension because of the corresponding block weight (12') the arms forming triangular supports (8) are affected by compression.
With the arrangement described above, the tensions go directly to main reins (11) tightened in the main tower CA 02203478 1997-0~-20 (b).
Moreover, if the machine is subjected to the action of winds of different intensity, wings (c) and (c') are not rigid (as said above) since the joints (9) enable the partial rotation of blocks (12') which form the meshed structure (12), starting from the final wing block (c)-(c') to continue with the lower block. (as shown in figure 5.) Besides, each of blocks (12') rotates partially , the tightness of said lower secondary reins (13') decreases, blocks (12') diverge, whereas the tightness in those reins (13') decreases. (se figure 4.) Also, there is a certain movement of the arms forming the triangular supports (8) limited by stabilizing reins (13).
Under these conditions and in spite of strong winds, the machine can advance with its wings (c) and (c') in perfect balance.
