Description

DESCRIPTION

Retractable fumigation arms accessory with air 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 system of retractable and folding arms is designed for spraying narrow crop lines where conventional machinery cannot access due to its dimensions. The arms are foldable ninety degrees and retractable, allowing their size to be increased to adapt to the growing conditions and the characteristics of the farm or greenhouse, they also have a lifting system by means of hydraulic cylinders. 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 rather, with the passage of the machine through a wider central aisle, several crops are treated even though they are narrower than the others. the machine itself. Sometimes, there is a metal structure in greenhouses that would make it impossible for the vehicle to pass with the arms fully open, so the arms are hydraulically retractable, which allows you to save it by closing them without having to get off the machine.

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 retractable hydraulic arms accessory constitutes in itself a novelty in its field of application, solving the aforementioned problem. Efficiency is greatly increased because, with the machine traversing through a single line or aisle, the arms allow the spraying of several rows of crops at the same time, and the air turbine shakes the leaves, increasing the impregnation of the phytosanitary product.

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 collapsible, being able to open from a vertical position to a horizontal one, and retractable, increasing or decreasing the total length of the arms to adapt to the obstacles of the plantation.

The chassis is designed to easily hook up to compact hydraulic spraying machinery. The accessory has a lifting tower with a mobile support 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 mobile support of the tower so that the entire assembly is raised simultaneously. The arms are foldable from the vertical by the action of two other cylinders that make them rotate 90 degrees to a horizontal position. Inside the arms there are some guides that allow them to be extended hydraulically, by the action of two other cylinders, to adapt to the dimensions of the crop. At the end of each arm another smaller cylinder allows to pick up the last nozzle support or "hand" of the machine, which also has a torsion spring that allows the hand to rotate in case of colliding with an obstacle.

The air circuit begins with the movement of a hydraulic motor that activates a turbine, and this sends the air to the outside through a rigid and flexible pipe channel through PVC mittens directed at the crop.

Some fumigation nozzles fed by a circuit of hoses that are connected to the machine to which it is installed are installed near the air outlet.

The circuit is also hydraulically powered by the machine itself, to which it is installed as an accessory.

Preferred embodiment of the invention

The air turbine accessory for agricultural hydraulic machinery is made up of a fixed metallic chassis lifting tower (1) which serves as a fastening to the machine and in turn guides the mobile support of the lifting tower (2) so that the entire set of arms and tower (2) moves vertically adapting to the crop, driven vertical movement by a hydraulic cylinder (9). The mobile support of the lifting tower (2) supports the arms and the air turbine itself (10).

The arms are subdivided into three parts, the folding arms (3) that rotate vertically ninety degrees, from being perpendicular to a horizontal position with it, by the action of a hydraulic cylinder (6); the extensible arms (4) which move longitudinally inside the folding arms (3) sliding through guides, being able to position themselves hydraulically to adapt to the distance between the crop lines and avoid obstacles, also by activating another cylinder (7); and some final "hands" (5), which have another small cylinder (8) that make it possible to collect them hydraulically, and also have a torsion spring so as not to suffer damage in the event of a collision with any object or brace of the farm, allowing it lower without having to activate the small cylinder (8).

The turbine with its hydraulic motor (10) is installed on the mobile support of the lifting tower (2) which rises and falls together with the set of arms by the action of a lifting cylinder (9). When the motor is activated, the turbine (10) generates air that is transported through a pipeline of flexible and rigid PVC tubes to PVC mittens (11) through which it exits directionally to move the leaves of the crop and to better impregnate the phytosanitary liquid that comes out of some fumigation nozzles (12) placed near the PVC mittens (11).

Both the hydraulic circuit to move the turbine motor (10) and the water circuit for crop spraying are powered by the machine to which the retractable arms accessory will be attached.

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