DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an irrigation system comprising on one hand a self-propelled irrigation carriage provided with drive wheels and a spraying boom or high-volume discharge sprayer and, on the other hand, a pipeline which is laid on the ground and along which the carriage is movable back and forth and from which water can be transferred, via a transfer unit connected to said carriage and movable together therewith, to a fluid motor or the like which also is mounted on the carriage and adapted to drive the drive wheels, and from there to one or more spray nozzles on the spraying boom or discharge sprayer.
In a known irrigation system of the above-mentioned type, the transfer unit of the irrigation carriage is formed of an elongate chamber which sealingly encloses a portion of the pipe-line during its movement therealong. Thus, the chamber more or less slides along the pipe-line which, therefore, must have an entirely smooth outer surface without obstructing joints. As a result, the pipe-line will be unnecessarily expensive in manufacture and, furthermore, must be laid absolutely straight. A further disadvantage is that the pipe-line, because of the sliding engagement with the chamber, is subjected to wear, and the removal and replacement of a damaged or worn pipe-like section is both time-consuming and expensive.
The present invention has for its object to obviate the above-mentioned disadvantages, which is accomplished in a manner which is as ingenious as it is simple in that the pipe-line is provided on its outer surface with equidistantly spaced apart clamps each having a valve extending through the pipe-line wall, and that the transfer unit comprises at least one chain or the like which is passed over guide pulleys and on which there are mounted, at intervals corresponding to the interspaces between the clamps, connectors which are successively movable into correct position opposite an adjacent clamp and are provided each with one actuator which opens the respective valve when the connector is in correct position.
In this manner, the pipe-line may be manufactured of commercially available quickly coupled light-metal pipes or hoses, thereby reducing the costs for making and laying the pipe-line. Moreover, the pipe-line need not be anchored in the ground and thus is readily moved from one field to another.
During movement of the carriage along the pipe-line, the connectors are stationary relative to the pipe-line which thus is not subjected to wear, and consequently there is no risk of any leakage between the connectors and the clamps.
A further advantage is that a defective pipe-line is readily repaired simply by replacing the damage pipe section or clamp.
The features of the present invention may best be understood by reference to the following description taken in connection with the accompanying drawings which illustrate an embodiment which, at present, is especially preferred.
FIG. 1 is a schematic lateral view of a self-propelled irrigation carriage and a pipe-line associated therewith.
FIG. 2 is a further schematic view of a part of the carriage and the pipe-line as shown in FIG. 1 on a larger scale.
FIG. 3 is a section substantially along line III--III in FIG. 1.
FIG. 4 shows a part of FIG. 3 on a larger scale.
The self-propelled irrigation carriage shown in the drawings and generally designated 1 comprises a frame 3 which is supported by drive wheels 2 and on which a spraying boom or high-volume discharge sprayer (not shown) of more or less conventional design is mounted.
The self-propelled irrigation carriage 1 is movable back and forth between the ends of the area to be irrigated, along a pipe-like 4 which is laid on the ground and preferably consists of commercially available quick-coupled standard-type light-metal pipes or hoses which can be laid directly on the ground and thus are readily moved from one location to another.
A transfer unit generally designated 5 is connected with the irrigation carriage 1 and movable together therewith. The transfer unit 5 serves to transfer wat
