ARTICULATED TRACTION GROUP WITH ACCESSORIES

The present invention relates to an articulated traction group to which certain accessories can be attached, in order to carry out different tasks on farmland along narrow aisles defined between rows of plantations. It consists of a front structure for driving this, where the engine and maneuvering mechanisms are arranged, and a rear structure where, in addition to a 500 liter tank, according to each type of use, there is a treatment equipment Phytosanitary products (formed by phytosanitary treatment bars or an atomizer) or a rake. This equipment is essentially characterized in that the front and rear structure are coupled to each other by means of an articulation mechanism and assistance means for the maneuvering commands of the traction equipment, while said mechanisms and said assistance means are capable of act together, allowing to achieve very small turning radius easily by the driver.

SECTOR OF THE TECHNIQUE

This invention has its application within the industry dedicated to the manufacture of equipment, devices and elements applicable in agriculture in general and, according to the accessory in question, phytosanitary or cleaning machinery in particular.

STATE OF THE TECHNIQUE

Currently all operations carried out in greenhouse crops deserve the greatest attention; among other things you have to adapt them to different types of greenhouse and different types of crops.

In this way, some problems of great interest arise when it comes to mechanizing the crops, so the machines must have smaller dimensions to be able to enter through their narrow aisles or their low entutorados.

The agricultural machinery is really attractive in this sector, since the high levels of temperature and humidity that are reached in the greenhouse make working conditions for operators more difficult and exhausting. The development

of machines that facilitate the work and even perform a large number of the functions that are found daily in a greenhouse will be of vital importance for an increase in production and efficiency.

The advantages of this articulated group with respect to other machines used in greenhouses is its versatility to adapt to any type of greenhouse or crop, where thanks to its articulation mechanisms allow very small turning radii inside the greenhouse, where the spaces of maneuvers are reduced in most of them.

In addition, thanks to its phytosanitary equipment, it is able to offer a high quality in the distribution of phytosanitary products, which is essential to achieve good biological efficiency and to minimize the risk to the environment during application. The use of appropriate techniques and technologies for the application of these products is a requirement of the utmost importance to achieve the desired efficacy in the control of pests, diseases and weeds, while reducing the risk of environmental impact of phytosanitary treatments .

A good application provides important advantages: greater efficiency, since the product is distributed evenly and with its correct dose over the entire surface to be treated; a better environmental performance, since it is possible to deposit the maximum quantity of product where it is necessary, minimizing the dispersion in the environment; a reduction of the remains of culture broth, since the more precise the application is, the more accurate the calculation of the broth necessary to perform the treatment is, reducing the remaining broth to be eliminated; and greater security for the operator, since it is not so close at the time of application.

DESCRIPTION OF THE INVENTION

The articulated traction group with accessories constitutes in itself a novelty within its field of application, being a versatile machine for greenhouses with soil crops, since it reduces the human presence inside the greenhouse during the tasks to be performed , such as cleaning in leaf and waste aisles or the application of phytosanitary products, thus achieving an improvement in the working conditions of the operator.

More specifically, the articulated traction group is constituted by a front structure for driving it, where the engine and maneuvering mechanisms are arranged, and by a rear structure where the accessories are arranged, whose dimensions are adapted to the of any type of greenhouse. Said chassis is made of st-37 steel, which provides the entire assembly with great robustness, in addition to being covered by two layers of paint, the first primer to consolidate and equalize the absorption of the paint over the entire surface, and achieve thus a better finish that protects the entire product.

Said chassis is supported on four off-road wheels, and the front structure (driving structure) and the rear structure (accessory carrier structure) are coupled to each other by means of an articulation mechanism and assistance means of the maneuver commands of the traction equipment during their movement, which are capable of acting together, allowing turning radius of 1.20 meters.

The articulation mechanism is defined by a hinge-like coupling comprising a fork fixed to the drive structure and articulated connected to the accessory holder structure and to said assistance means of the maneuver commands. The fork is a double fork that has a longitudinal and a transversal section.

The longitudinal section consists of two parallel arms that represent respective holes for mounting a through bolt through a bushing fixed to the accessory holder structure. The bushing is housed between the upper and lower arms of the longitudinal section. The command assistance means include a hydraulic piston articulated to the accessory carrier structure, while the free end of its piston has a bushing fixed through which a bolt fixed to the end of the transverse section passes. The piston is connected to a hydraulic pump for its operation and for its displacement during the turning maneuvers.

The equipment is moved by a driving system that moves the assembly, being a diesel or electric motor, which gives the team a greater torque, and therefore a greater power when working at low revolutions.

For the vehicle's traction system, four hydraulic motors are driven, each coupled to a wheel to achieve total hydraulic traction independently. The system is controlled through a variable flow pump.

AND! Spray system consists of a reservoir, a treatment bar and a spray pump. Both the pump and the bar are driven by a hydraulic motor, which is regulated by solenoid valves and driven through the pump. The vertical treatment bar is fixed to a support bar by means of rods, and they are equipped with flat or conical jet nozzles. The system can also have an atomizer attached, consisting of a fan with a large air turbine.

The spraying system can have extensible horizontal arms that move by means of a hydraulic system composed of cylinders. The extendable arms are attached to the support thanks to an extension, and can move vertically through the support.

The sheet cleaning system consists of a rake, composed of a support with a vertical extension, attached to the frame with the spikes or brushes by means of some arms, which are moved by three cylinders that generate three types of hydraulic movement: ascent , inclination and approximation.

The electrostatic spray system consists of an electronic device, a boiler, electric diffusers and electrostatic nozzles.
