Description

DESCRIPTION

Extendable hydraulic arms accessory

The present invention refers to a hydraulic accessory for agricultural machines conceived for the application of phytosanitary product in seedbeds and narrow crops. This system of extendable arms is used for the fumigation of agricultural lines where conventional machinery cannot access due to its dimensions. These arms are foldable in three parts by means of hydraulic cylinders, which facilitates movement within the growing area and its subsequent storage. It also has a lifting tower to save the different heights in the growing process 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 operations 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 process of spraying the phytosanitary product was done manually, with pressure spraying backpacks, which was tedious and ineffective for the work of the operators. Then the hydraulic spraying machines arrived in the sector, and with it the efficiency, speed and greater control of impregnation of 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 aisles are so narrow that they do not allow the passage of the machine to be used.

The extendable hydraulic arms accessory allows the phytosanitary product to reach the crop without having to access the machine through the line or corridor where it is located. Explanation of the invention

The extension hydraulic arms accessory constitutes in itself a novelty within 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 three or more cultivation lines, depending on the length required by the greenhouse or seedbed to be treated.

More specifically, the arms are made up of a metal tube chassis that provides robustness to the assembly, whose dimensions are adapted to different types of crops. Said chassis is covered by a protective anticorrosive paint.

The arms are foldable to allow movement inside the greenhouse and to facilitate the storage of the machine and the passage through doors and areas narrower than the treatment area.

The accessory is divided into three parts, one that allows the vertical movement of the arms (lifting tower), and two other extendable parts that we call "arm", the first folding of the structure, and "forearm", the second folding of the latter. of the attachment is achieved through hydraulic cylinders.

The cylinders that allow the opening of the forearms, in turn allow the rotation of the tubes where the spray nozzles are placed, making sure that when the arms are in a horizontal position, these tubes remain in a totally vertical position, allowing them to be inserted into the corridors of the crop so that the phytosanitary liquid remains impregnated in the plantation.

The end of said tubes is prepared to be able to connect a herbicide dispersion hood, for cleaning the center of each aisle.

The hydraulic machine to which this accessory is to be attached is fitted with a hydraulic distributor with three levers, one for controlling the lifting tower, another for activating the cylinders on the right arm and another for actuating the cylinders. of the left arm.

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

Preferred embodiment of the invention

The extension hydraulic arms accessory that can be coupled to an agricultural machine is made up of three clearly differentiated parts, the lifting tower for the arms (1), and two structures each divided into an arm (2) and a forearm (3). The left and right side structures are folded down thanks to the action of two hydraulic cylinders (4), one for each structure. The same cylinder (4) opens the arm (2) and forearm (3) consecutively.

Tubes (5) are placed in the structure, which serve as support for the spray nozzles (6), adding tubes (5) according to the lines, or corridors, to be fumigated.

These tubes (5) have a horizontal position with respect to the lateral structures of the accessory when it is folded. With the help of a mechanical system, when opening the arms (2) and forearms (3), the tubes (5) rotate until the cylinder (4) is completely open, leaving these perpendicular to the lateral structures of the accessory.

The tubes (5) are prepared to be able to attach a herbicide hood (10) for cleaning the corridors of the greenhouse or seedbed.

The lifting tower (1), moves vertically so that the arms are at the desired height for each crop. Thanks to another hydraulic cylinder (9) and a chain system this movement is achieved.

In the agricultural machine to which the attachment is coupled, a hydraulic distributor (7) is installed with three levers (8) that control, one the lifting of the attachment, another the lowering of the right frame, and the other the lowering of the left frame. .

The lateral structures can be completely folded without fumigation, remaining perpendicular to the ground, positioning the forearm (3) next to the arm (2) facilitating the movement of the machine, and opening completely, leaving these parallel to the ground to start the fumigation.

Both the lifting tower (1), as well as the arms (2) and forearms (3) are made of steel, covered by a protective anticorrosive paint.

The system is fed by the own hydraulic circuit of the agricultural machine to which the attachment is coupled.
