Abstract

Device for spraying plants, comprising an inverted "U" shape, the plant being able to remain between both wings of the "U", characterized in that it comprises a fan (1.1, 2.1) located on the upper part of the "U", to absorb the drops not deposited in the plant, which includes separate air outlets in connection with separate air ducts (1.2, 1.3) located on the wings of the "U" and which are attached to separate ducts (5) that transport the liquid to be sprayed comprising, at the lower ends of the "U" wings, two upwardly oriented sprayers.

Description

Device for spraying plants.

Object of the invention

The present invention relates to a device for spraying a fluid material, Generally for the treatment of plants.

The device object of the invention comprises inverted "U" shape so that the plant would be located between both wings of the "U", it also includes means that allow to absorb the powdered drops but that have not been deposited in the plant, as well as some material exits pulverized that allow a better access of this one to the leaves of the plants to be sprayed

Background of the invention

Spraying devices are known that they comprise an inverted "U" shape so that the plant would be between both wings of the "U". These devices they comprise a reservoir in which the mixture is generally made 3 of water and the fluid with which you want to treat the plant, this tank is attached to a distribution conduit of the same that is extends on both wings of the "U" and that finally has some means for spraying the treatment liquid on the plant. These spray means D are normally located on the wings of the "U" so that the flow leaves the sprayer perpendicular to the wings of the "U" attacking horizontally to the floor. Two "U" wings can understand a recovery system of those drops that leave Vegetation during treatment. These usually consist of some recovery panels located internally on both wings of the "U" comprising slots that allow collecting said drops that are recovered and sprayed again.

However these devices present the inconvenient that the sheets do not get wet conveniently wasting a lot of product even with mentioned recovery panels.

The present invention solves the previous one technical problem by means of a device comprising means spray and recovery that result in greater application effectiveness.

Description of the invention

The present invention relates to a device for spraying a fluid material on plants, usually for treatment.

The device object of the invention comprises inverted "U" shape, leaving the plant between paths wings of the "U", further comprising a fan located in the top of the "U" to absorb the drops not deposited in the plant comprising at least two departures from air in connection with at least two air ducts located in the wings of the "U" and that join two ducts that they transport the liquid to be sprayed that they understand at their ends bottom of two wings of the "U" two sprayers oriented upwards.

The fact that the sprayers are located at the bottom of both wings of the "U" and not in the intermediate part of them, makes the material flow pulverized attack the plant from the bottom of the leaves of so that there is greater contact between the sprayed liquid and the same.

Also the fan located in the part top of the "U" along with the conduits that redirect these drops caught back to the sprayers manages to create a kind of closed circuit of that material that does not reach leaves and that is reabsorbed and sprayed again.

Preferred Embodiment of the Invention

An example of embodiment in which there are two spray devices of plants (1, 2), both united, through two arms telescopic (4), to a tractor that has a tank (3). In the embodiment shown the reservoir (3) of the fluid to be sprayed it is placed on the tractor and is delivered to each device spraying (1, 2) through two ducts (5).

Each spray device (1, 2) is it places around a plant (6) or a row of plants (6).

Each spraying device (1, 2) it comprises a fan (1.1, 2.1) located at the top of the "U" to absorb the drops not deposited in the plant. From this way an upward suction current is created that attracts the drops towards the fan (1.1, 2.1).

The fan (1.1) comprises two outputs of air in connection with two air ducts (1.2, 1.3) located on the wings of the "U". In the embodiment shown the ducts of air (1.2, 1.3) are joined by their lower end to the ducts (5) of liquid to be sprayed, the lower ends being (1.2.1, 1.3.1, 5) oriented towards the top of the "U" and They finally have some sprayers.

The fan (1.1, 2.1) can be centrifugal and it can have a metal or plastic mesh (7) below that prevents leaves from the plant from accessing the fan (1.1, 2.1).

In the exemplary embodiment shown in the figures both in the front and in the back of the "U" comprises a frame (8) whose purpose is to reduce the section of the "U" and thus increase turbulence. This frame (8) It includes soft plastic ribbons that have cuts cross-sections that reduce the possible damage to the leaves of the plant (6).

For better material distribution sprayed on the floor (6) the air ducts (1.2, 1.3) no They face each other.

In the case where the plant (6) has a considerable height is also possible the existence of at least an outlet of the pulverized material at medium height of both wings of the "U". This exit will preferably be oriented towards the top of the wings of the "U" in order to achieve a better spray on the leaves.

Claims (9)
