Abstract

The combination consists of a tubular rod (1) whose internal cavity acts as a water and/or nutrient reservoir. The filling of this cavity is made through the top whereas its emptying is through the bottom via an adjustable flow rate drop by drop distribution system (7). The rod internal space is subdivided into two chambers by a transverse partition (4). The upper chamber (14) contains the water and nutrient and the lower chamber (15) discharges into the drop by drop distribution system. The partition has a valve (4) able to control the flow of liquid from the upper to the lower chamber. This valve comprises a needle obturator (6), which is fixed to a float (5) located in the lower chamber, engaging an orifice (40) in the partition.

Description

THE TUTTER-SPRINKLER FOR SHRUB AND MASSIVE TREE
The present invention relates to a guardian-sprinkler device making it possible to effectively maintain any tree, shrub, ornamental plant and vegetable farmer requiring support.

In addition, this device allows sparse and regular watering according to the needs of each plantation, which can range from a few hours to a few days, without requiring a bulky and expensive installation (pump, buried pipe, electricity, drip pipe or d 'watering).

Indeed, many trees, shrubs and plants cannot benefit from correct and regular watering due to their isolation or remoteness.

- The purpose of this device is to replace the traditional wooden stake with a fairly limited lifespan by a hollow plastic stake much more solid, resistant and aesthetic. n can be produced in several forms, diameters, thicknesses, colors, this in order to best blend with the environment where it will be used. The device allows significant savings in irrigation water, due to the very low flow rate and evaporation of water (small irrigation area, maximum use of water for the needs of the plant). This results in financial savings, due to the installation, its longevity allowing several uses over many years and a reduced footprint.

- The second function of Invention is a water reserve whose drain rate will be adjustable which will allow watering from a few hours to several days depending on the need.

A financial saving due to the installation, its longevity allowing several use over many years and a reduced space requirement.

Aesthetic because this sprinkler stake can be produced in several forms, diameters, thicknesses,
colors, this in order to best confuse it with the medium where it will be used. It will be lighter, more
handy, cleaner and eliminates any risk of injury during handling (splinters,
spikes etc ...).

It is a simple system without risk of wear or breakdown due to its manufacture without organs
mechanical.

It can be fitted with permanent fixing straps but replaceable if necessary, but
also a removable liquid fertilizer tank.

It can be dressed in stones and this will reveal a very decorative element in a massif
DESCRIPTION OF THE GUARDIAN
Figures "1""2""3" illustrate the invention.

With reference to the latter, the device comprises:
It will consist of a plastic tube "the body" (1) of sufficient thickness for good rigidity. The tutor's "head" (2) will also be plastic, but full, of identical size to the "body" (1), of sufficient height to be able to strike it with a hammer, in order to firmly sink the tutor-sprinkler into the ground. hard. In the case of a manufacture in several elements a shoulder will complete the "head" (2) allowing it to enter the body or it will be screwed or glued according to the manufacturing method used. The "foot" (3), of the tutor-sprinkler will be in solid plastic also of the same size as the body and will end in a point at the other end.

According to the manufacturing method used, the largest part of the "foot" (3) will also be equipped with a shoulder allowing its insertion into the body, but must nevertheless be strong enough to allow a very resistant fixing of the whole. The point will be long enough for good support on the ground and may be conical, smooth or with more or less pronounced fins depending on the manufacturing method used, but must prevent the rotation of the stake once in place. At the upper part of the "body" (1) a "filter" holder (4) and a "filter" (5) will be inserted in an "orifice" (6) made low enough not to prevent the possible installation of head, obstructing the sprinkler-guardian. fi will be fine enough to trap the maximum amount of impurities in the water. It will be of sufficient diameter for easy filling. The lower end of the "body" (1) will also be provided with an "orifice" (7) but threaded in order to receive a "drain" device (8), this will be offset by a quarter of a turn, or even opposite the "orifice" (6), thus allowing not to have the filling in front of the trunk to which the stake will be fixed. "The orifice" (7) will also be made high enough to possibly receive "the foot" (3), and allow to have a reservoir in order to collect impurities not trapped by the filling "filter" (5). .

The "drain plug" (8) will be provided in its center with a "needle valve" (9) allowing precise adjustment of the flow rate. The thread pitch of the needle will be large enough to limit the number of turns between the opening and closing of the "tap" (9). A "tubing" (10) placed after the tap will allow the reception of a pipe. A "washer" (11) engraved from 1 to 7 will define the setting.

The "body" (1) is formed at the base of a chamber with a reserve of water at constant level to allow a regularity of the flow of the drip thereby eliminating the pressure drop caused by the drop in the level d in the "body" (1).

This chamber with reference to Figure 2))>, consists of a "calibrated diaphragm" (12), a "needle" (13) and a "float" (14).

The diaphragm separates the chamber from the body. The needle obstructs the orifice of the diaphragm.

The float allows the needle to be raised in order to maintain a constant level of water in the chamber. The assembly is guided vertically to avoid possible malfunction.

An "orifice" (15) is made in the upper part of the chamber to bring the latter to atmospheric pressure.

The end of the "tap" (10) will be made of reaction material
hygrometric and will change color, therefore, will indicate when the tutor will be empty.

This type of watering can have other applications, so for the massive more or less important, it can then be simply a reserve of water but of greater capacity. It will then be of a greater diameter and a height adapted to that of the shrubs found in the massif, it will also have several sprinkler systems distributed around the circumference to irrigate the maximum of shrub, it can then land on the ground simply. Equipped with a suitable system and a particular ornament it can serve as a very appreciable support and of great use for outdoor lighting or as a support for a basin and many other uses.

In the case of online use (tomato hedge etc ...), connected to several by a hose, filling the first will allow the filling of the others.

By way of nonlimiting example; a sprinkler-tutor who would have the following dimensions:
Body height = 200 cm and diameter = 10 cm would have a capacity of approximately = 15 liters of water, set at a flow rate of two liters per day, (daily need for a medium tree) will allow constant watering of seven days.
