FR3041500A1 - BRUSHCUTTER PROTECTION FOR HEIGHT ADJUSTABLE HEIGHT AND BORDER - Google Patents

Abstract

The invention relates to a brushcutter housing as an accessory and can be attached to most brushcutters called "angular gear" without modifications, fixed on the brushcutter removably, and adjustable for the height of mowing. This crankcase comes as an addition to the existing protections on brushcutters, mowers or rotary cutting head clippers by angle.

Description

This invention is based on the so-called brush cutting machines with angular head (8) fig.3 and rotary cutter. The set of commercial brushcutters has a housing positioned behind (9) fig.3 of the section so as to protect the user from the projections made during cutting by the rotation of the cutting device, wire teeth or disc.

The current and known brushcutters have plastic protective housings injected about one-third of the mowing diameter (9) fig.3 and this on the rear part to provide protection for the user but nothing stands in the way. the front (front) and on the sides (side) of the machine, projections of elements on the ground such pebbles, vegetation, or other. . Unlike the mower and rotary cutting system and traditional mower tractor, brushcutters are not provided with full or frontal protection, or side.

As a result, there are significant potential risks of injury to people on the periphery of the machine as well as the risk of damage to nearby material goods such as vehicles, buildings, glass or other, within a radius of up to twenty meters. by the projection of elements when using the brushcutter.

It is indeed difficult to be able to have full protection of its brushcutters because the evacuation of the mowing in the rotary system and difficult to channel through an exhaust outlet that can be traditionally on a mower or a tractor that then are concentrated in a collection bin.

The current decks of the brushcutters are minimized so as to have a significant projection of the cutting waste.

The brushcutters must also be as light as possible because they are generally worn by the user and non-rolling like lawnmowers and tractors.

Integral protection of the trimmers would therefore be feasible only by a heavy and complicated system that can be found in part in the patent application EP0 756 814 A1.

The innovative housing is composed of connecting adapters (2) fig. 1 or connecting pieces fixed by tightening screws on the arm of the brushcutter. These same link adapters hold a tube (3) fig.1 by lights for clipped fastening and for height adjustment according to the positioning on the lights between the tube (3) fig.1 and the connecting adapter (2). ) fig. 1. The housing (1) fig.2 is fixed to the tube by a screw (10) fig. 1 which allows a pivotal connection to the turn of this screw.

Optionally the housing (1) fig.2 can receive one or hinges (4) fig.2 for tilting one side of the housing. In the case of this option a latch (5) fig.2 makes it possible to lock the tilt in order to maintain the casing in its original and closed form.

The present invention is therefore to have an adaptive projection protection system while keeping the possibility of having an efficient mowing on grasses or brush and, a protection that allows the evacuation of the mowing while keeping an environmental protection of the user and an efficient mowing system.

The device of the invention is adaptable to different models but above all is removable by the connecting adapters (2) fig. 1 and does not change the conformity of the brushcutters.

It is important to note that any modifications of the approved systems would remove the conformity of the device and / or the device. The invention therefore provides additional protection on the front and side faces unlike other devices and also allows the extraction of the elements of clippings, grasses or brush.

Clipper casings or tractors of clippings are generally made of steel sheet and presents the evacuation and the extraction by a routing either towards an outside side or towards a collecting tank.

The decontactor casings are generally on the back of the mowing as we can find it on the patent FR 2 572 247.

In the case of the invention, the evacuation is conveyed by a volume and a lateral clearance (7) fig.7 and rear output. The advantage of this device is that it does not make use of many heavy and expensive systems but that it is obtained solely by the rotation and the speed of rotation of the wire (11) fig.6 to drive in this space and this clearance (7) fig.7 the residue of mowing to extract them outside the protection This reduced space located between the original protective cover and the housing of the invention allows its radius greater than the radius of the housing of the brushcutter, to extract the residues of clippings in a laminar flow by this lateral clearance (7) fig.7. It allows among other things to obtain the same extraction function that we can find on lawnmowers or lawn tractors.

The present case of innovation has on all its periphery a skirt (6) fig. 1 raised allowing the use in lateral as in frontal.

When using the brushcutter, it frequently happens that the angled head (8) fig.3 abuts on the ground. The shape of this skirt (6) fig.1 makes it possible to make a ski to the whole of the brushcutter and thus allows it to slide on the ground, even irregular when it is a movement forward as on the rated because of its continuity on the whole housing (1) fig.2.

The housing can, optionally, receive one or more hinges (4) fig.2 on the side part. This hinge option allows the crankcase to raise a lateral part in order to use the rotary cutter on the side fig.5 and fig .6 with the brush cutter, while keeping the protection and the extraction by the side clearance (7) fig .7 the opposite of this device.

This cutting process by the side allows among other things to make a cut along a wall, a sidewalk or a tree.

The tube (3) fig. 1 upper that connects the housing to the brushcutter ensures effective maintenance of the product and prevent rotation by the lights and slots created especially on the tube (3) fig. 1.

These lights also allow following the clipping on the link adapters (2) fig. 1 a setting of the height of mowing to achieve. The higher the assembly is positioned on the openings of the tube and the higher the height of the mowing.

By associating the skirt (6) fig. 1 on the periphery and the connection of the tube (3) fig. 1 adjustable in height, the trimmers can be used as a traditional mower and allows to have a constant support on the ground keeping a height determined by the positions of the tube (3) fig. 1 on the adapter adapters (2) fig.1 of the innovative housing.
