Abstract

Agriculture. Harrow of the type comprising a framework 1 supporting a series of teeth 9, characterised in that the framework 1 comprises a series of channels 4 extending substantially vertically, each channel receiving a sleeve 5 of flexible and elastic material in which a tooth 9 is engaged, means being provided to hold the teeth in the said corresponding sleeves 5.

Description

La présente invention vise une nouvelle herse. The present invention relates to a new harrow.

On connait différents types de herses qui sont généralement constituées d'un bâti qui est attelé à l'arrière d'un tracteur et qui comportent des dents qui en pénétrant dans le sol permettent d'ameublir la couche superficielle de celui-ci. Les dents s'usent rapidement et leur remplacement constitue une opération longue et onéreuse. We know of different types of harrows which generally consist of a frame which is hitched to the rear of a tractor and which have teeth which, penetrating into the ground, make it possible to loosen the surface layer thereof. The teeth wear out quickly and replacing them is a long and expensive operation.

On connaît, également, différents types de herses vibrantes, ce qui évite le bourrage et dont les dents sont, soit, montées sur une lame de ressort, soit, mues d'un mouvement de vibration engendré mécaniquement. De telles herses, sont complexes, chères et le remplacement des dents usées est compliqué. Also known are different types of vibrating harrows, which avoid jamming and the teeth of which are either mounted on a spring leaf or moved by a mechanically generated vibration movement. Such harrows are complex, expensive and the replacement of worn teeth is complicated.

L'un des buts de la présente invention est de réaliser une herse qui remédie aux divers inconvénients ci-dessus. One of the aims of the present invention is to provide a harrow which overcomes the various drawbacks above.

La herse selon l'invention est du type comprenant un bâti supportant une série de dents et est caractérisée en ce que le bâti comporte une série de canaux s'étendant sensiblement verticalement, chaque canal recevant un manchon de matière souple et élastique dans lequel est engagée une dent, des moyens étant prévus pour maintenir les dents dans lesdits manchons correspondants. Grâce à cette disposition, on réalise une herse d'une conception particulièrement simple et d'un faible prix de revient et, dans laquelle les dents sont vibrantes, peuvent facilement être réglées, changées etc.. The harrow according to the invention is of the type comprising a frame supporting a series of teeth and is characterized in that the frame comprises a series of channels extending substantially vertically, each channel receiving a sleeve of flexible and elastic material in which is engaged a tooth, means being provided for holding the teeth in said corresponding sleeves. Thanks to this arrangement, a harrow of a particularly simple design and a low cost price is produced, in which the teeth are vibrating, can easily be adjusted, changed, etc.

Suivant une caractéristique particulière, le manchon comporte à chacune de ses extrémités un bourrelet en saillie, chaque bourrelet étant destiné à prendre appui sur l'extrémité correspondante du canal. According to a particular characteristic, the sleeve comprises at each of its ends a protruding bead, each bead being intended to bear on the corresponding end of the channel.

Suivant une caractéristique de détail, les moyens pour maintenir les dents dans les manchons comprennent deux bagues engagée sur chaque dent de part et d'autre des manchons et comportant des vis pointeaux et des contre écrous. On réalise ainsi, un moyen simple et peu onéreux de fixation des dents par rapport au bâti.  According to a characteristic of detail, the means for holding the teeth in the sleeves comprise two rings engaged on each tooth on either side of the sleeves and comprising needle screws and lock nuts. This produces a simple and inexpensive means of fixing the teeth relative to the frame.

Suivant une caractéristique constructive, les canaux, les dents, les trous des manchons et des bagues ont une section rectangulaire. According to a constructive characteristic, the channels, the teeth, the holes of the sleeves and of the rings have a rectangular section.

Enfin, suivant une dernière caractéristique, le bâti de la herse est formé de barres présentant des enfoncements et fixées par paires de manière que les parties concaves des enfoncements se fassent vis à vis pour former les canaux.  Finally, according to a last characteristic, the frame of the harrow is formed of bars having recesses and fixed in pairs so that the concave parts of the recesses face each other to form the channels.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté à la figure unique. The invention will now be described in more detail with reference to a particular embodiment given by way of example only and shown in the single figure.

La herse représentée aux figures comprend un bâti désigné par la référence générale 1 constitué de barres 2 convenablement pliées pour présenter des enfoncements angulaires 3. The harrow shown in the figures comprises a frame designated by the general reference 1 consisting of bars 2 suitably folded to present angular recesses 3.

Les barres 2 sont fixées deux à deux, par exemple par soudure de manière que les parties concaves des enfoncements angulaires soient situées en regard l'une de l'autre afin de former des canaux 4 à section carrée. The bars 2 are fixed two by two, for example by welding so that the concave parts of the angular recesses are located opposite one another in order to form channels 4 of square section.

Dans chaque canal 4 est logé un manchon de matière souple et élastique 5 qui présente à chaque extrémité en saillie un bourrelet 6, les bourrelets venant porter contre les bords des canaux 4. In each channel 4 is housed a sleeve of flexible and elastic material 5 which has at each projecting end a bead 6, the beads coming to bear against the edges of the channels 4.

Les dents de la herse portent la référence 9 et sont constituées d'un barreau de section carrée engagé dans le manchon corres?ondant 5 et fixé par deux bagues 10 et 11. The harrow teeth bear the reference 9 and consist of a square section bar engaged in the corresponding sleeve 5 and fixed by two rings 10 and 11.

La bague 10 vient s'engager sur l'extrémité supérieure de la dent 9 et comporte un toron taraudé dans lequel se visse une vis pointeau 12, destinée à se ficher dans la dent, un contre écrou de blocage 13 étant prévu. The ring 10 engages the upper end of the tooth 9 and includes a threaded strand into which a needle screw 12 is screwed, intended to be inserted in the tooth, a locking nut 13 being provided.

La bague ll est montée sur la dent 9 de manière à venir buter contre le bourrelet 6 correspondant du manchon et comporte, comme la bague 10, une vis pointeau 12 et un contre écrou de blocage 13. The ring ll is mounted on the tooth 9 so as to abut against the corresponding bead 6 of the sleeve and comprises, like the ring 10, a needle screw 12 and a locking nut 13.

Les dents 9 ont une longueur importante de manière qu'on puisse rattraper l'usure en les faisant coulisser après avoir desserré les bagues 10 et 11. The teeth 9 have a long length so that wear can be caught by sliding them after having loosened the rings 10 and 11.

Comme le manchon 5 est élastique, lorsque la herse est passée sur le sol, les dents 9 seront animées d'un mouvement de vibration ce qui évite le bourrage. As the sleeve 5 is elastic, when the harrow is passed over the ground, the teeth 9 will be animated with a vibration movement which avoids jamming.

On a représenté les dents avec une section carrée, rris bien entendu elles peuvent avoir ainsi que les manchons 5 et les canaux 4 une autre section.  The teeth are shown with a square section, of course they can have as well as the sleeves 5 and the channels 4 another section.

Bien entendu, l'invention n'est pas limité au mode de réalisation qui vient d'être décrit et représenté. Of course, the invention is not limited to the embodiment which has just been described and shown.

On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention. Many modifications of detail can be made without departing from the scope of the invention.
