Description

Extendable and retractable hydrant The invention relates to a retractable connection, ß for buried newspapers or the like. Which after use with Manual power or automatically can be sunk into the ground, 'to a ma. fast Processing of ground areas such as grassland, sports grounds, field airfields, etc. to enable and after this processing the connection or several such connections with the existing operating pressure of the water or the like. again automatically for further use to extend.

A substantial manual labor saving is achieved. Until now Movable above-ground material was used, which is provided with quick-release fasteners and requires labor and transport to operate.

The invention is illustrated, for example, in a drawing. she is that a cattail 3 in amen tubular cylinder 1, with the normal operating pressure of the water or the like 1. can be pushed up out of the ground and thus the Connection part 5 for the actual connection through the ground to the surface brings. On the upper end of the cattail 3 is an easily removable one Countersunk cap 4 put on, which through the pointed shape for better penetration serves the earth layer and also with a bore with a nozzle-like opening 6 is provided to by the jet effect of the water coming from the main line or the like. the penetration of the countersunk cap 4 to the surface is much easier. In addition, the IX.i.-se 6 is also used to drain the amount of water that is used when sinking of the connection 5 from the descending piston 2 from the lower part of the tubular cylinder 1 is displaced.

There is also a quick release fastener at the upper end of the piston rod 3 or another suitable connection option for quick attachment any nebulizer device of known design, which again after use is removed and replaced by the countersunk cap 4. The hydrant or hydrants 6 can after use by hand using a recessed bar II with a recess for the countersunk cap 4 can be pushed back into the earth. This operation can also carried out automatically by introducing pressurized water above the piston 2 will. For sealing the piston in the upper position during the operation provides a ring seal device 2. The connector 7 is used for connection of the cylinder to the one laid in the ground - indicated on the drawing - shown Main line. The main line is expediently laid so deep into the earth that Neither they nor the connections, which were sunk after four irrigation, made the processing of the Dodens, (tillage zone 9 plus safety zone 10) e.g. drarch plowing or Do not disturb the mowing of grain or grass with 1. machines, and neither do they by heavy agricultural tractors or the like. to be damaged. Preferred depths of the main line are about 70 cm below the floor surface, depending on the intended use.

To replace the attachments or the tip 4 when under pressure To enable standing line, the quick release 5 with check valve provided, which opens automatically when the seats 4 or the implement are removed or asleep.

With this device any liquids such as water, liquid fertilizers, insecticides or finely ground suspensions Solids of any kind, as well as Gases or other finely divided substances can be quickly and easily atomized over large areas.

The individual parts of the claimed device can be made of metal or completely resp. are partly made of plastic. - The metal parts can also inside and outside with a protective layer or a protective material made of plastic or other known such substances.

The great advantages of this device are, among other things, its simple construction and deep storage in the ground after use without the use of masonry or metal boxes that get in the way of working the floor, and the amount of work involved save on.

Claims (1)

PATENT CLAIM 1.) Extendable from the ground and retractable hydrant for irrigation connections, irrigation connections, etc., connected to an underground stationary feeder line by , g, Pfkl ennzei_chnefi, that in a tube cylinder 1 installed underground, a tube piston 3 with normal operating pressure through the safety zone above it 10 and the cultivation zone 9 is pushed upwards. 2.) The extendable and retractable Hydrant characterized. that the upper part of the bulrush 3 is provided with a countersunk cap 4 in a conical design to allow better penetration of the soil. 3.) Extendable and retractable hydrant dadurgh gehtnzeichn. That the countersunk cap 4 is provided with a nozzle 6 in order to facilitate an ihi.rchdringen of firmer soil through the jet effect. @ +.) The extendable and retractable Hydrant characterized characterized. that when the hydrant is lowered through the nozzle 6, a displacement of the amount of water below the cattail 3 is made possible. 5.) The extendable and retractable Hydrant characterized in that the connection part 5 is made of quick-locking with check valve, to allow a substitution of sprinklers sprinkler hoses, etc. without releasing the operating pressure. 6.) Extendable and retractable hydrant thus ggjrennzeichent. that the sinking into the ground can be done by a simple lowering rod II.
