"Hydraulic cylinder with water-bearing piston rod as a sprinkler carrier for an irrigation system "

The Heiieriing concerns a hydraulic cylinder with a water-bearing Kolfeen rod as an Eegneransch ^ a sprinkler system. The supply line is below the Plur. Cylinders of this type are known, but so far they have always been arranged close to the surface of the earth, so that it was not possible to carry out soil cultivation or other field work unhindered, in particular to plow the soil allowing uitten in '& en _cylinder: opens a water supply pipe whose upper end protrudes beyond the cylinder surface and JLbschluB to: as above the cylinder, preferably entspreehend of; soils machining depth cm more than 40 under the soil surface, -verlaufende water feed line is formed and -that is the Kolbenausfahrlänge according to the Bodenbearbeitungstiefi ^u Very than 40 cm.

The piston has a hole in its center for the water supply into the basket rod · A profile seal, optional with additionally built-in spiral spring for preload, closes the basket against the cylinder wall «

The piston rod consists of a water-carrying ear. she is firmly connected to the piston at the lower end · The piston rod has a stop that, when fully extended, * · -. - ■ ■. - .-. ■ -'- ..

Optionally, a G-compression spring can be used for automatic lowering the piston rod must be installed in the cylinder. You load

can be found between the lower side of the cylinder cover and the top of the piston · The counter-pressure spring pushes when the piston is deflated Sprinkler line the piston with the piston rod up to & back the stop on the cylinder base.

A plastic pipe -connects the sprinkler pipe with the

* hydraulic cylinder. It is attached to the built-in parts of the cylinder connected to the sprinkler line and to the lower one Side of the cylinder attached below the piston during its lowest position. ■

The overall length of the cylinder is essentially determined by the length of the piston rod, which in turn depends on the required underground installation depth of the system. The diameter of the cylinder depends on the sum of the

♦ Resistance to be overcome, around the water-bearing piston rod by the water pressure required for the sprinkler to bring the earth's surface.

I ^{1 For} the irrigation system with underground control lines and retractable rain shutters, the following installation

systems of sprinkler pipes:

Underfloor sprinkler cable for field widths of up to 120 m in the center of the field relocated. Irrigation hoses are attached to the retractable sprinkler connections connected, at the end of which you can see the sprinklers on slide stands. Allow the irrigation hoses several sprinkler setups from one sprinkler connection. This system with fully stationary pipeline, supplemented by

_ Zj. _

the viewing pleasure requires for its acquisition a relatively low capital expenditure «.

Underfloor sprinkler line, as described above, with buried Side lines made of PE pipes instead of the irrigation hoses · All sprinkler positions are on the irrigation surface a permanent connection. Is see a fully inpatient System in which only the sprinklers are moved must * This piping system is suitable for large 3-line lengths * :

Underground sprinkler line according to the already known network system, i.e. in / this case to be laid underground PE tubes of the smallest possible diameter with a Number of opponents connections, but only simultaneous operation from one or two opponents pe ßohrleitungsstrang. It is also a fully stationary system in which only the sprinklers are to be moved · This drilling pipe system suitable for short 3-field lengths.

Underfloor opponents lines with retractable opponents connections can also be used for sprinkling gardens, parks and sports fields as well as the irrigation of industrial wastewater are used

When commissioning the irrigation system with underground rain pipes and retractable Eegneransehlüsse the slide on the emptying device of the sprinkler line is closed and the Streekensehieber between the main line

and the sprinkler line open. Compartment, - switching on the pump unit fill see the sprinkler pipe, and the water is pushed into the hydraulic cylinders «

The water pressure created on the underside of the pistons increases the piston rods with the plug-in valves to the surface of the earth »

The sprinklers are then connected to the plug-in valves by hand and start working immediately.

Hoses can also be connected to the plug-in valves at the other ends of which see the sprinklers on sleigh stands condition" . -

The retractable sprinkler connections are shut down the system is returned to its original position by after switching off the pump unit, clamp the strainer valve The main line and the sprinkler line are closed and the drainage valve of the sprinkler line is opened. The piston rods After removing the sprinkler, the hydraulic cylinders are pushed to the bottom with a special stick key pressed into the earth in the cylinder. Unless see the Cylinder G-compression springs are located when the pump unit is running the slide valve closed, the sprinklers removed and then the emptying slide of the sprinkler line geöff £ gi <3t · Then the piston rods sink automatically to to the lower stop of the cylinder. The piston rods can also be brought into their sunk position by generating a negative pressure in the sprinkler line.

The main advantages of the underfloor sprinkler line with retractable sprinkler connections compared to the previously known ones Irrigation systems consist in eliminating the physically demanding and time consuming work of installing quick release tubing in the fields during irrigation not applicable · The 3 plant stocks are largely

protects, as no more pipelines are laid in the cultures

vi the »By countersinking. the kegner connections can also during the required field work without hindrance during the irrigation season be carried out by irrigation material. The opponents lines, which are preferably made of plastic, are subject to this no wear and tear and do not require any maintenance. the Storage of pipe material outside of the irrigation season ent falls. The installation of the negative pipes can be done by farmers or
