Description
SPECIFICATION
Irrigation or other machine having a rotatable drum carrying a hose or other flexible element wound thereon
The invention relates to a machine to be driven or otherwise propelled along the ground and carrying a rotatable drum, reel or other like carrier (hereinafter called a drum) on which a hose, cable, wire or like flexible element is wound in a plurality of side-by-side convolutions in at least one layer and from which the hose or other said flexible element can be unwound therefrom and rewound thereon.
The invention is particularly, but not exclusively, concerned with a hose-drum irrigation machine of the kind having a rotatably driven drum carrying a hose wound thereon in a plurality of side-by-side convolutions, in at least one layer and communicating at one end with a source of water or other liquid to be discharged through the hose while wound or partly wound on the drum and at the other end with an irrigation gun, sprinkler or other liquid discharging device.
In known hose-drum irrigation machines of this kind, the hose is wound on the drum in side-by-side convolutions in at least one layer and is unwound therefrom by a hose-laying device comprising a lead-screw driven in synchronism with the drum and having forward and reverse threads thereon and extending parallel to the axis of rotation of the hosedrum and a nut engaging the threads of the lead-screw and carrying a guide through which the hose passes, or an equivalent mechanism to provide reciprocating travel of the hose-guide, whereby as the drum is rotated, the hose-guide will be reciprocated parallel to the axis of rotation of the drum and thereby the convolutions of the hose on the drum in one or more layers will be formed thereon or removed therefrom.
It is important in such a hose-laying device that the convolutions of hose on the drum are not loose or do not become loose and therefore an object of the invention is to provide a tensioning device acting on the hose as it is unwound or re-wound on the drum.
Although the foregoing object is directed to a hose-drum irrigation machine, it may also be applied to any other machine to be driven along the ground and having a driven drum on which another flexible element, such as a cable or wire, is wound in a plurality of sideby-side convolutions in one or more layers.
According to the invention, an irrigation or other machine which is to be driven or otherwise propelled along the ground and which carries a drum, as hereinbefore defined, having a hose or other flexible element wound thereon in a plurality of side-by-side convolutions in at least one layer, includes a hoselaying devide by which a hose-guide is reciprocated parallel to the axis of rotation of the drum as the drum is rotated, and a tensioning device engaging the outer surface of the hose or other flexible element at a position adjacent the hose guide, the tensioning device including driving means therefor operable to pull or to exert a drag on the hose or other flexible element as it is being unwound or re-wound and thereby to maintain the hose or other flexible element in tension and thereby to prevent the convolutions on the drum from becoming loose with respect to the drum periphery.
The driving means in the tensioning device may be a hydraulic or other fluid-operable motor or an electric motor. The drum and the lead-screw or equivalent device may also have driving means comprising a hydraulic or other fluid-operable motor or an electric motor.
Where the driving means in the tensioning device and the drum driving means are both hydraulic or other fluid-operable motors they may be connected in a circuit including adjustable valve means, whereby the tensioning device motor creates a back-pressure on the drum driving motor, thereby to ensure that the latter cannot be operated until the backpressure has been produced by the operation of the motor of the tensioning device.
The circuit may also include a valve acting across the motor of the tensioning device which is adjustable to produce a predetermined resistance when said motor is driven by the tensioning device when the drum is being driven in the winding direction.
The machine may also include switch means positioned adjacent the hose or other flexible element as it approaches the hoseguide on being re-wound or leaves the hoseguide on being unwound, whereby deviation of the hose or other flexible element from a normal position as a result of a difference between the linear velocity of the hose or other flexible element and the ground speed of the machine will stop both a motor driving the machine and a motor driving the drum.
A hose winding and unwinding device in a hose drum irrigation machine as hereinbefore defined is now described by way of example with reference to the accompanying drawings, in which: Figure 1 is a side elevation of the hose drum and a hose-laying mechanism incorporating the hose winding and unwinding device;
Figure 2 is a detail view on the line ll-ll in
Fig. 1 of part of the device shown in Fig. 1;
Figure 3 is a view in the direction of arrow
A in Fig. 2;
Figure 4 is a fluid control circuit including two motors also shown in Figs. 1-3;;
Figure 5 is a diagram showing a pair of switches also shown in Fig. 1 for controlling the motors shown in Fig. 4 in response to deviation of a portion of the hose beneath the device as shown in Fig. 1 from a normal position during its winding or unwinding as a result of a difference in linear speed of the hose and the ground speed of the machine, and
Figure 6 is a diagram showing the use of the pair of switches shown in Fig. 1 to reverse the direction of rotation of the hose drum.
Referring first to Fig. 1, the hose-drum 1 is mounted for rotation on a shaft IA substantially parallel to the ground and to the longitudinal centre line of a chassis, not shown, on which the hose-drum is mounted; that is the axis of rotation of the shaft extends in the direction of travel of the chassis. The shaft IA is driven through reduction gearing from a hydraulic or other fluid motor 18. The hose 25 is wound on the drum in one or more layers of side-by-side convolutions by means of a hose-laying mechanism comprising a hose-guide device 8 which travels along a reversed threaded lead-screw 5, first in one direction and then in the opposite direction.
The lead-screw 5 is driven by a chain-andsprocket drive 3,4 from a chain-driving sprocket 2 mounted on the shaft IA. Thus rotation of the hose drum in the winding or unwinding direction by the motor 1 8 also moves the hose-guide device 8 in one direction or the other along the lead-screw 5 and so the hose 25 is wound on or is unwound from the drum 1 progressively along the axial length of the drum in one or more layers.
Such a mechanism is known in hose-drum irrigation machines. In Fig. 1 the hose 25 is connected at one end thereof remote from the machine to a fixed hydrant and supplies through the convolutions on the drum and the shaft IA which is hollow, an irrigation gun or boom, not shown, mounted on the machine.
In hose-drum machines as known hitherto, the hose-guide device is usually in the form of a nut which travels along the lead-screw 5 and through which the hose is guided and travels with the nut in the axial direction of the lead-screw 5. The hose-guiding device 8 illustrated in Figs. 1-3 comprises a frame 6 which includes a screw-threaded part which engages the lead-screw 5 or which is mounted on a nut engaging the lead-screw and so the hose-guiding device 8 travels bodily along the lead-screw 5. The frame 6 supports two pairs of guide rollers 24 engaging against the outside of the pipe 25 at diametrically-opposite positions and, across the diameter at 90 to the rollers 24, a further pair of guide rollers 1 6 and an endless friction belt 1 2 supported on pulleys 1 3 and 14.The belt 1 2 has external teeth thereon which are drivingly-engaged by a toothed driving pulley 15 driven by a motor 19. The hose-speed is monitored by a speed sensor 26 driven by one of the hose-engaging rollers 1 6 or 24 and may be compared with the ground speed of the machine or the speed of a motor driving the machine. The motor 18 and the machinedriving motor (not shown) may be fluid operable, e.g., they may be hydraulic motors.
Alternatively the motors may be electrical. The drum speed and the ground speed of the machine can be maintained substantially equal and thereby permit the hose 25 to be wound onto or to be unwound from the drum at the correct tension despite change in effective drum diameter as the layers of hose are formed or reduced and so the hose convolutions will normally tend to be held tight around the drum 1.
In accordance with this invention, the endless friction belt 1 2 is provided to pull the hose from the drum 1 in the hose-unwinding sense, thereby to ensure that the convolutions remain tight on the drum. Where the drumdriving motor 1 8 and the belt-driving motor 1 9 are hydraulic or are other fluid-operable motors, they are connected in a fluid circuit shown in Fig. 4. The circuit includes an adjustable valve 22. This is set to apply a back pressure created by the motor 1 9 on the motor 18. The motor 1 8 cannot function until it has been subjected to this back pressure and so ensures that the hose is pulled from the drum 1 and the convolutions of the hose on the drum are maintained tight.The circuit also includes an adjustable valve 21 which is set to create a predetermined resistance when the motor 1 9 is driven by the endless belt 1 2 as a result of winding the hose 25 onto the drum 1 when the latter is driven in the winding direction by the motor 1 8. In this way a drag is imparted to the hose and the hose is maintained taut during re-winding.
The grip on the hose 25 between the rollers 1 6 and the belt 1 2 is adjustable by making the rollers 1 6 adjustable towards and away from the pulleys 1 3 and 1 4. Instead of using the endless belt 12, the tension in the hose 25 can be produced by an equivalent roller or rollers arranged to grip the hose together with the rollers 1 6 and arranged to be driven by the motor 1 9. A proportional control valve 20 reverses the direction of rotation of the motors 18, 19.
The device 8 also carries a pair of switches 7 and 9 mounted one at each side of the hose 25 as shown in Figs. 1, 5 and 6 and having operating members engageable with the hose at a pair of diametrically-opposite positions thereon. The switches 7 and 9 which are fluid-operable or electrical operate to stop both the machine-driving motor (not shown) and the hose-drum-driving motor 18 when one or other is engaged by the hose as a result of deviation of the hose in the vicinity of the switches 7 and 9 from a normal position occupied by that part of the hose when the drum speed and ground speed are equal. The normal position of the hose 25 is indicated in Fig. 5 by full lines and in that condition neither switch 7 and 9 is engaged by the hose.Where the ground speed of the machine is the datum and the drum fails to match the required speed or ceases to rotate, continuing travel of the machine will attempt to drag the hose along the ground and the hose will deviate to a position such as position
A on one side or the other of the normal position, according to the direction of travel of the machine. Thus the appropriate switch 7 or 9 will shut down both the drum-driving and machine-driving motors. If the machine should stop while the drum continues to be driven, the hose will take up the position indicated at B in Fig. 5, at one side or the other, and so the switch 7 or 9, as appropriate, is operated to stop both the drum-driving and machine-driving motors.Where the drum speed lis the speed datum and the ground speed of the machine fails to equal the drum speed, any deviation of the hose from its normal position to the position shown at A or
B in Fig. 5 will effect operation of the appropriate switch 7 or 9, thereby shutting down the machine.
The switches 7 and 9 therefore act as failsafe devices which will protect the hose from damage during a machine malfunction.
The switches 7 and 9 may also be operated simultaneously to effect reversal of the hosedrum and machine-driving motors when the hose 25 has been fully re-wound onto the drum 1, by providing on the hose adjacent the hydrant a shoulder 28, which may be a pair of connecting flanges between the hose and the hydrant, engageable with the switches 7 and 9, as shown in Fig. 6.
Although the hose-laying device in the embodiment illustrated comprises a lead-screw and nut, an equivalent mechanism to provide reciprocating travel of the hose-guide as the drum is rotated may be employed.
Although the invention has been applied to a hose-drum irrigation machine it may alternatively be applied to a similar driven machine having a cable- or wire-winding drum thereon.
