OBJECT OF THE INVENTION

The present invention relates to a mechanical machine-

hydraulic, which is coupled to the arms of an agricultural or industrial shovel,

capable of clearing through weeds the weeds accumulated on the ground

cultivated fruit or omamental trees.

Known brushcutters are large capacity machines

they engage behind the tractor vehicle to the tripunta and are driven by the

PTO of the tractor. To work they are mounted on one arm

Hydraulic motor driven. In its back goes the turret and the box

of gears. There are three types: chains that rotate clearing

Kills and hammers that crush the grass.

Brushcutters are increasingly used due to a

Significant increase in ecological farms. good for

market demand, or by impulse of policies and subsidies of

the European Unit, being in these cases totally prohibited the

herbicide application. Therefore, an increase in demand is expected

of this type of large area brushcutter.

Currently, the market for these machines is supplied

exclusively of rear brushcutters, whether fixed or articulated.

They present many difficulties when working in tree cultivation cellars, due to the difficult maneuverability offered by the tree trunk when the cellar is attacked from the rear of the tractor. Often you have to go around very difficult execution, difficult maneuvers and

In addition, the driver does not directly see the work that develops the brushcutting, but must continually look back to control it.

For all the above, the problem is novelly resolved

10 by the present invention, placing the machine in the front of the towing vehicle, coinciding the direction of its clearing work with that of the direction of the vehicle, coupling to the arms of the blade and accommodating the hydraulic arm of the blade to allow any maneuver without damaging the tree, as well as work even on very steep slopes

15 steep terrain. Among its main advantages, the following stand out: The clearing is now located in the front of the tractor vehicle, allowing the condUlotor to see the work he is doing in front and being able to undertake the task without difficult maneuvers

It is quick hitch

The hydraulic arm allows movement in all directions and

slopes, clearing the cellars without having to do as many maneuvers as with the desb, rear brush. BACKGROUND OF THE INVENTION

5 Although no identical invention has been found to the

described by the inventor, we present below the documents found that reflect the state of the art related to it.

Thus, document ES1 017001 U refers to a brushcutter, which includes a horizontal front axle, supported on a frame provided with two wheels and a maneuvering lance, said being

shaft connected to a motor to print rotation movement and being

bearer of a plurality of hammers distributed along it and in an angular direction, whereby the cutting is carried out in front of the machine, having provided that the shaft and hammers are protected by

15 an upper housing and two plates. acting side supports

Bearing for said shaft and that at the same time determine means of support and stabilization of the machine by having two lower skates. The

The main difference with the proposed brushcutter is that the comparator rests on wheels. being therefore less manageable than 20 with the hydraulic arm of the desbrolzadora object of this invention.

The document ES1017123U describes a machine brushcutter of plant debris, of the type of the cClnstituted by a frame in which

Rides a transmission that receives the movement of the tractor vehicle and

whose transmission puts into operation an angular multiplier that at

in turn, and by means of a transmission, rotates a longitudinal shaft of

the machine in which some hammers are mounted by means of appropriate supports in solidarity with the tree, and also the machine has rolling means consisting of a rotating cross roller and an inter-tree plate, in addition to which it is fixed to the rear detachable frame a retainer OR last point of shock provided with supports on which the rakes of a rake are coupled and regulated, and also a baffle rotatably fixed to the frame and to its

10 and the crushed matter; while the inter-tree plate transmission system consists of a horizontal transverse axis driven by

belts which connects to an angular transmission case from which

a pulley for the control of the plate comes out and in addition this transmission makes the plate itself fully exposed and positioned so that it is peripherally effective in the cut, with the horizontal tree at its ends, and on the inside, about Bearing supports of the axis of rotation, so that in case of breakage of said axis the shaft d and the machine cannot be detached. Its constitution, in addition to being very complex, is rear-wheel drive, which makes the difference quite

20 of the proposed invention.

ES1064235U proposes an improved brushcutter,

of the type that, destined to mow or clear weeds or harmful plants of a land, or the roadsides and roads, incorporates a small engine, and through a tubular body incorporates a

gimbal mechanism, ensures the rotation of the lower circular body in which

S 10

it has a plurality of threads that by means of such rotation act as a blade, which rotates the lower Gircular body existing at its distal end and that is provided with 2, 4, 6 or 8 threads, being joined, by means of an coupling configured by an arm articulated, to a tractor vehicle, said arm being preferably located, on the right side of the tractor, so that it can rotate on said side forward until it reaches the front wheel thereof, without limiting its placement on the opposite side ,: It is a brushcutter of threads for shoulders and slopes in roadways, very different from that which is the subject of the present invention with the exception of the articulated arm.

ES1068295U describes an improved hydraulic brush cutter adapted to potato harvesting, taking advantage of the hydraulic power coming from the tractor itself, according to a support provided with articulation that is fixed to the rigs, existing on the front of a tractor and the brush cutter itself. In fact, more than a brushcutter, it is a potato picker, so it is quite separated from the brushcutter object of the present invention.

Conclusions: As can be seen from the research carried out, none of the documents found solves the problems raised as the proposed invention does.

DESCRIPTION OF THE INVENTION

The front brushcutter for tree and woody caves

For tractors of medium and long-term power, the object of the present invention is constituted from a projecting central front arm of the hydraulic structure of the shovel of the tractor vehicle, once the 5 bucket of the shovel of said hydraulic structure has been removed, engaging the two hydraulic arms of said structure by means of two hooks. Said front arm rotates horizontally around its articulation point moved by a hydraulic piston and has at its end a turret on which a hydraulic motor is located which, through a gearbox, rotates a disc coupled to said box by means of a hook. fast, to whose head the chains are attached that turn when brushing the weeds horizontally, also being able to hook to said head blades that cut the weed, being the tractor vehicle the one that provides the energy of the arms of the blade, of the piston and of the hydraulic motor on turret. The

The position of the disc can be regulated through a mechanical articulation of the end of the front arm, which can optionally be hydraulic through a piston.

In a different embodiment, a tractor is incorporated into the tractor vehicle.

auxiliary pressure pump with oil tank for feeding the

20 hydraulic motor for the case where said tractor vehicle did not have

sufficient flow to move the hydraulic motor.
