[0003] The rotating head claimed has been conceived to resolve the previously stated problem,
wherein based on a support structure formed by a hook frame and a closing lid, as
means of location and protection for the corresponding motor-reducer, it presents
the special feature that a water inlet piece with special collar flanges has been
secured to the frame between the lid and the reducer, which delivers more or less
flow and pressure to the water, with means of securing it to the lid and a clamp pertaining
to a tube wherethrough axially passes a rod, the tube whereof is finished in its lower
part in an operative head formed by the combination of a piece through which passes
a bearing axle with spraying nozzles, the head or referred to piece being connected
to the rod and being actuated by a pair of conical crown gears, with their corresponding
safeguards. With these basic characteristics, and depending on the type of elements
that are disposed on the head, pressures of up to 210 bars and flows of up to 280
I/min can be achieved, compared to the conventional pressures of 85 bars and flows
of 45 I/min.
[0005] As can be observed in the referred to figures, the head of the invention is comprised
of a hydraulic motor with the possibility of a motor propelled by water, using the
same cleaning pressure (1) associated to a reducer (2), with the interposition of
an appropriate transmission (4), so that said transmission is situated between the
motor output shaft (1) and the reducer input shaft (2), also providing a clamp (3)
for anchoring the motor (1), through legs (6) secured by its other end to a second
clamp (8), as represented in said figures, with the special feature that one clamp
(7) situated after the reducer (2) and through legs (9), which are longer than the
previous, the unit is secured to the clamp (11) pertaining to a tube (12), on whose
other end is mounted the corresponding operative head of the head. A water inlet (10)
is situated between the legs (9), finishing off in its lower part the entire unit
of motor (1), reducer (2), legs (6) and (9) and inlet (10), by a lid (13), secured
to the end of a frame (14) formed by two U-shaped, orthogonally inverted and crossed
arches, with an upper ring (14') determining a means of hooking for the raising and
lowering of the head unit. Regarding the transmission (4) between the motor (4) and
the reducer (2), it has two pieces joined therebetween, to one of which, as already
mentioned, is connected the motor output shaft (1), while the other is connected to
the reducer input shaft. For their part, both the legs (6) and the legs (9), the latter
considerably longer than the former, are formed by threaded rods for their attachment
to said corresponding clamps, also having provided that the motor (1) with the reducer
(2) are provided with means of protection to avoid possible accidents. Regarding the
water inlet piece (10), as one of the main elements of the head, it has special collar
flanges, remaining situated below the reducer (2), as already mentioned, specifically
being the piece that facilitates the entrance of the water or product that the head
uses, piece (10) which defines a water tank with small boxes for housing of the corresponding
collar, in accordance with the different pressures, flows and products to be used,
this piece being provided with tubes (15) ending in a threaded piece (16) for the
attachment of corresponding valves or tubes that transport the fluid, such as the
corresponding clamp with holes for the passing of the securing legs (9). For its part,
the lid (13) is provided for the closing of the corresponding cistern inlet, securing
the frame (14) thereto, and its attachment to the clamp (11) of the tube (12). As
previously mentioned, the operative part of the head is mounted in the lower part
of the tube (12), providing a shaft (17) axial to the said tube (12), in contact with
and connected to the interior part of the water inlet piece (19), having on the lower
end of that shaft (17), inside the tube (12), a crown (18) that gears with a second
crown (19), through a conical gear, both protected by respective safeguards (20) and
(21). The crown (18), considered the larger crown, is provided to carry out the different
movements made by the head, while the different rotations are made through the crown
(19), considered small, being anchored to a cross shaft (22) wherein the corresponding
nozzles (23) are mounted, having provided that in this unit, specifically on the lower
ends of the shaft (17), the piece or head (24), which is cylindrically configured
and has three flat faces and edges finished off at 45° is mounted, making its aspect
peculiar and its function that of determining a water tank, which, the same as the
water inlet piece (10), incorporates collar flanges and flanges for corresponding
O-rings and lids. Regarding the safeguards (20) and (21) of the crowns (18) and (19),
they are provided to avoid accidental blows to said crowns, and made of curved rods.
Regarding the shaft (22), as a piece that passes through the head (24), it supports
the small crown (19), while at its other end it secures the corresponding nozzles
(23); said shaft (22) being hollow inside and blocked up at the end where the crown
(19) is mounted, so that the water passes from the head (24) to the nozzles (23),
with bores provided for that, and it being possible for said shaft (22) to vary according
to pressure and flow, thereby varying the head model. Finally, the nozzles (23) can
be of different types; they can be standard nozzles, large and secured nozzles, or
large and movable nozzles, to achieve different flows, in accordance with the needs
of each case.
