Description

L'invention concerne des appareils de motoculture-du genre Motohoue
Motobineuse ou Motofraise, ctest à dire destinés à effectuer des opérations de fraisage de binage ou de sarclage du sol.
The invention relates to garden equipment of the Motohoue type.
Power hoe or Power mill, that is to say intended to perform hoe milling operations or weeding the soil.

Les appareils de ce type comportent des outils rotatifs montés aux 2 extrémités d'un arbre horizontal et entrainé en rotation par un moteur, l'avan- cement de l'appareil s'effectuant soit par.les outils eux-memes, retenu par un éperon soit par-une roue avant motrice. Devices of this type include rotary tools mounted at the two ends of a horizontal shaft and driven in rotation by a motor, the advancement of the device being effected either by the tools themselves, retained by a spur either by a front wheel drive.

Ces machines qui conviennent parfaitement dans bien des domaines d'uti- lisation ne permettant cependant pas d'effeetuer des travaux de précision ou de nombreux changements de direction doivent 4tre effectués, passage d'un rang à un -autre entre 2 planta, sarclage dans des plantations très étroit étroites en serre par exemple', binage'des fleurs, des bordures d'allées, éct. These machines, which are perfectly suited in many fields of use, do not, however, allow precision work or many changes of direction to be made, switching from one row to another between 2 plants, weeding in very narrow, narrow greenhouse plantations, for example ', hoeing' of flowers, aisle edges, etc.

Pour effectuer ces travaux il est nécessaire de disposer d'un appareil très léger et très maniable; le but de l'invention est de réaliser cet appareil. To carry out this work it is necessary to have a very light and very handy device; the object of the invention is to produce this device.

A cet effet l'appreil de motoculture suivant l'invention est composé d'un chassis tubulaire sur lequel est fixé en partie centrale, un moteur, en partie arrière un carter de transmission étroit comportant les outils rotatifs, en partie avant 1 roue porteuse de grand diamètre, le prolongement vers le haut et vers l'arrière du chsssis tubulaire forme la potence de guidon, le guidon étant fixé sur la dite potence par l'intermédiaire du support guidon ét de 3 silentbloc, afin d'attenuer les vibrations des outils rotatifs et du moteur. To this end, the garden equipment according to the invention is composed of a tubular chassis on which is fixed in the central part, a motor, in the rear part a narrow transmission housing comprising the rotary tools, in the front part 1 load-bearing wheel. large diameter, the upward and rearward extension of the tubular frame forms the handlebar stem, the handlebar being fixed on said stem via the handlebar support and 3 silentbloc, in order to attenuate the vibrations of the tools rotary and motor.

Le principe de fonctionnement est le suivant : dans une motobineuse classique l'avancement de la machine est assuré. par les outils rotatifs qui en pene-.The operating principle is as follows: in a conventional hoe the advancement of the machine is ensured. by the rotary tools which do.

trant dans la terre propulse l'appareil vers l'avant. La vitesse d'avancement est limité par un éperon solidaire de la partie arrière qui freine cette vitesse plus ou moins en fonction de la pression exercée sur l'éperon. Dans une motofraise la vitesse d'avancement est règlés par la roue avant motrice dont le régime de rotation est calculée en fonction du travail a effectuer. @
Dans le cas de l'invention la vitesse d'avancement est assure par les outils rotatifs du carter arrière comme dans une motobineuse classique mais ré- gulée par un frein manuel agissant sur la roue porteuse avant.Ce frein peut autre soit à tambour agissant dans le moyeu de la roue, soit par l'intermédiaire d'un doigt venant frotter sur le bandage pneumatique ou par tout autre moyeu approprié.
trant in the ground propels the device forward. The forward speed is limited by a spur secured to the rear part which brakes this speed more or less depending on the pressure exerted on the spur. In a milling machine the forward speed is regulated by the driving front wheel whose rotation speed is calculated according to the work to be done. @
In the case of the invention, the forward speed is ensured by the rotary tools of the rear casing as in a conventional hoe but regulated by a manual brake acting on the front carrying wheel. This brake can be either drum acting in the wheel hub, either by means of a finger rubbing against the tire or by any other suitable hub.

Dans le cadre de l'invention on dispose donc d'un appareil très léger puisqu'il n'y a pas de transmission mécanique sur la roue avant motrice, d'ou une grande simplicité de fabrication, et extrement maniable puisque çette roue sert à diriger l'appareil et à lui faire prendre toutes les prientations dési rées.  In the context of the invention, therefore, a very light device is available since there is no mechanical transmission on the driving front wheel, hence great simplicity of manufacture, and extremely handy since this wheel is used for direct the device and make it take all the desired prientations.

L'invention a également pour objet des mo modes de réalisation comportant l'une au moins des caractéristiques suivantes :
- - Le support de guidon qui est le prolongement du chassis tubulaire est articulé au point de rencontre dans, le sens horizontal, permettant un déplacement du guidon de part et d'autre de l'axe longitudinal.
