Description

DESCRIPTION

Arms accessory and air and fumigation turbine

The present invention refers to a hydraulic accessory for agricultural machines designed for the application and dispersion of a phytosanitary product in seedbeds and crops. This folding arm system is designed for spraying narrow crop lines where conventional machinery cannot access due to its dimensions. The arms are foldable ninety degrees and have a lifting system by means of hydraulic cylinders, and they are also extensible, adjusting their length manually to the dimensions of the crop. These features facilitate the mobility and movement of the machine around the work area. An air turbine moves the leaves of the plantation facilitating the impregnation of the phytosanitary products of the crop.

Technical sector

This invention has its application within the industry dedicated to the manufacture of equipment, devices and elements applicable in agriculture in general and accessories for phytosanitary machinery in particular.

Background of the invention

Currently all the operations that are carried out in greenhouse crops and seedbeds deserve the greatest attention; Among other things, they must be adapted to the different types of greenhouse and the different types of crops and terrain.

Previously, the phytosanitary product spraying process was done manually, with pressure spray backpacks, which was tedious and inefficient for the work of the operators. Later, the hydraulic spraying machines arrived in the sector, and with it the efficiency, speed and greater control of the impregnation of the phytosanitary product in the crops. The impossibility of applying said machinery in some nurseries and greenhouses is presented in their design; when the lines or corridors are so narrow that they do not allow the passage of the machine to be used.

The extensible hydraulic arm accessory allows the phytosanitary product to reach the crop without the entire machine passing through each line of the greenhouse, but instead, as it passes through a wider aisle, several crops are treated even though they are much narrower.

In addition, the accessory has an air turbine that makes the plantation shake and allows the products used in the fumigation to adhere better to the crop.

Explanation of the invention

The hydraulic extendable arms accessory constitutes in itself a novelty in its field of application, solving the aforementioned problem. Efficiency increases considerably due to the fact that, with the machine running through a single line or aisle, the arms allow the spraying of several rows of crops at the same time, and the air turbine stirs the leaves, increasing the impregnation of the product. phytosanitary

More specifically, the arms are made up of a metal chassis that makes the whole robust, whose dimensions are adapted to the crop, and covered with a protective anti-corrosive paint.

The arms are folding, from a parallel position next to the side of the machine up to ninety degrees with it, being also extensible, increasing its length, thus allowing movement inside the greenhouse and easy storage of the machine.

The chassis is designed to easily hook up to compact hydraulic spraying machinery. The accessory has a lifting tower that moves by means of rollers through guides by the action of a hydraulic cylinder. Both the turbine and the arms are installed on the tower so that the entire assembly is raised simultaneously. The arms are foldable horizontally by the action of two other cylinders that make them rotate ninety degrees with respect to the side of the machine. Inside the arms there are guides that allow the arms to be extended manually to adapt to the dimensions of the crop.

From the horizontal arms rise other vertical ones made up of a metallic structural tube where the fumigation nozzles are located and to which other PVC tubes are attached. PVC tubes are connected via flexible tubing to the turbine so they can be easily stretched and bent. In addition, some holes are made through which the air coming from the turbine comes out to shake the leaves of the crop.

Brief description of the drawings

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part of said description, where for illustrative and non-limiting purposes, the following has been represented: Next:

Preferred embodiment of the invention

The air turbine accessory for agricultural hydraulic machinery is made up of a chassis (1) which serves as a fastening to the machine and in turn guides the lifting tower (2) so that the entire set of arms (3) and tower (2) are move vertically adapting to the crop. The lifting tower (2) supports the arms and the air turbine itself (4).

The arms (3) are subdivided into three parts, the folding arms (3.1) that rotate horizontally ninety degrees, from being parallel to the machine to move and store without problems to being perpendicular to it for fumigation work; the extensible arms (3.2) which move longitudinally to the folding arms (3.1) sliding through some guides, positioning them manually to adapt to the distance between the crop lines; and the vertical arms (3.3), which are made up of vertical metal tubes (8), which support the fumigation nozzles (5), and the PVC tubes (6) that have holes through which the air coming from the turbine (4) for agitation of the leaves of the crop, which benefits the impregnation of the same by the phytosanitary products. The PVC tubes (6) are connected to the turbine (4) by flexible tubes (7).

Both the lifting movement of the tower (3) and the folding of the arms (3) are provided by three hydraulic cylinders (9), one for lifting and two for the folding, one for each arm (3).

The system is powered by the hydraulic circuit of the agricultural machine to which the accessory is attached.

The dimensions of the accessory are adapted to the type of crop, and all the metal parts are covered with protective anticorrosive paint.
