FR2797146A1 - Irrigation device, for storing and supplying water to plants, consists of tube with series of holes, inclined upwards, at lower end, just behind point - Google Patents

Abstract

The irrigation device consists of a tube (1), which has one of its extremities (6) fitted with a point (4) and is pierced with a series of holes (3) just above the point. The holes are pierced at an angle to incline upwards away from the point, to prevent them being blocked as the point is inserted in to the ground

Description

The present invention relates to a device for maintaining and supplying plants with water. The device meets two basic requirements - to be installed by pressing into all the floors, - to ensure, by holes drilled in the direction of the top, a supply of coolant in the right place and in an amount equal to each supply.

Before their rooting, plants, trans-plants, trees, vegetable or ornamental vegetable crops, need a stake to maintain their verticality and watering, with or without fertilizer, to facilitate the development of the roots and thus ensure its development autonomy.

Certain current devices make it possible to make a tutor by watering on the surface, as described in application FR 2 761 573 comprising a supply from the network, with a "filter" holder and a filter, the emptying taking place in its lower part via a drip distribution system with adjustable flow. Similarly, in application FR 2 761 572, where the device is identical to the previous one, the emptying takes place at the bottom via a "emptying" system which is provided with a "needle valve".

The same applies to application FR 2 758 044, where the supply of liquid is made at the surface and by adjustable drip.

As for the device described in application FR 2 735 653, the supply is made below the level of the roots by an orifice blocked by compacted earth introduced at the insertion of the device. Furthermore, penetration into the ground is random or even impossible, the stones located in the ground remaining trapped in the bevelled section of the mouthpiece not blocked.

The device as described in application FR 2 654 301 cannot be put in place by pressing in because of its "plug" at the bottom and of the "threading cuff". In application FR 2 374 843, there is no no plant maintenance function, the device being connected to a pressurized network.

The device W 09727735, sprinkles on the surface and cannot be planted, because it requires a "tip of insertion". Furthermore, it does not keep plants out of the ground for their growth.

As for the device described in application FR 2 709 400, the water arrives by a drop formation device ". 11 is connected to a distribution pipe, the water being able to exit by a system known as:" by self-tapping screwing " There is also no device that can keep plants out of the ground for its growth.

The dispositiffaisant the object of the invention and described below allows - to be implemented by pressing without damage to the water diffusion system. - make a water supply in the right place (level of the roots) underground and therefore avoid excessive evaporation (water spreading by gravitation and capillarity) - build up a reserve of liquid always equal to each intake (volume of the tube).

- to serve to maintain the plants during their growth using fasteners. The accompanying drawings illustrate the invention. FIG. 1 represents in section, the device of the invention.

Figure 2 shows the drilling of water drainage holes (drilled upwards) Figures 3a and 3b show the device in section at the level of the holes.

Figure 4 shows, in section, a reinforced tube. The device consists of a simple tube (1), one end (6) of which is equipped with a tip (4), and the other end (2) of which is open.

Holes (3) are drilled on the tube (1) just above the tip (4) The holes (3) have bevelled sections (7), oriented upwards, in the opposite direction to the tip (4 ), to avoid blocking the holes (3) when the device is driven into the ground. The holes (3) can be of variable number and distributed on the periphery of the tube (1) see FIG 3a or be grouped see FIG 3b These hole arrangements (3) allow to have different waterings either distributed uniformly or centered on a zoned. In addition, the tube (1) can be reinforced by an internal spider (8), housed inside said tube (FIG 4).

To make filling faster, an independent funnel (S) can be added to the end (2) of the tube (1). The liquid thus introduced into the tube (1) spreads in an amount equal to the level of the roots.

Claims (5)

CLAIM 1) Device for maintaining and supplying plants with water, characterized in that it consists of a tube (1) one of its ends (6) of which is equipped with a point (4) and is pierced with holes ( 3) just above the tip (4). 2) Device according to claim 1 characterized in that the holes (3) have bevelled sections (7) oriented upward in the opposite direction of the tip (4) to avoid their obstruction when sinking into the ground . 3) Device according to claims 1 and 2 characterized in that the holes (3) are distributed uniformly on the periphery of the tube (1), or grouped to allow different waterings distributed uniformly or centered on an area. 4) Device according to claim 1 characterized in that the tube (1) is reinforced by an internal spider (8) housed inside said tube. 5) Device according to claim 1 characterized in that the tube (1) is provided with a funnel (5) at its end (2) to allow faster filling of said tube.
