Le dispositif est constitué d'un support (1) présentant une butée (2) et une bielle (3) dont l'extrémité inférieure est fixée à l'outil. L'extrémité supérieure comporte un anneau soudé fixé à un ressort (5). Le ressort (5) est attachée au support (1) à l'aide d'une tige filetée (6) maintenue grâce à un ensemble écrou / contre écrou (7) et rondelles (8). La tension du ressort et la vitesse d'avancement de l'élément tracteur détermine le pivotement et la pénétration de l'outil dans le sol. Ce dispositif est particulièrement destiné à la fixation d'un outil rotatif mécanique pour le travail des sols sur des plantations agricoles.The invention relates to a device for: 1) working the soils at a high rate between the rows of agricultural plantations; 2) reduce the risk of damage to plantations; 3) increase the penetration of the tool in the soil. The device consists of a support (1) having a stop (2) and a connecting rod (3) whose lower end is fixed to the tool. The upper end has a welded ring attached to a spring (5). The spring (5) is attached to the support (1) by means of a threaded rod (6) held by a nut / nut assembly (7) and washers (8). The tension of the spring and the speed of advance of the tractor element determines the pivoting and penetration of the tool into the ground. This device is particularly intended for the attachment of a rotary mechanical tool for tillage on agricultural plantations.

Description

DESCRIPTIONDESCRIPTION

La présente invention concerne un dispositif ajustable de porte-outil rotatif mécanique permettant le travail des sols à cadence élevée sur des plantations agricoles.The present invention relates to an adjustable rotary mechanical tool holder device for working high-speed soils on agricultural plantations.

Le travail des sols entre les rangs de plantations est traditionnellement effectué à l'aide d'outils mécaniques et/ou hydrauliques, comme les outils à lames (sarcleuse) ou les outils à socs (décavaillonneuses). Le pivotement de ces outils autour d'un obstacle (ex. : cep de vigne, tronc d'arbres fruitiers, etc.) est commandé par une tige nommée pare-cep dans le domaine agricole. Lorsque l'élément tracteur avance, la tige vient en appui contre l'obstacle et déclenche le mécanisme de pivotement de l'outil autour de l'obstacle. Les inconvénients de ce type de fonctionnement sont les suivants : (1) le travail des sols à de faibles vitesses (1.5 à 5 km/h) pour éviter d'endommager les plantations, (2) l'arrachement occasionnel des plantations, et (3) le déclenchement en continue du pare-cep lorsque la végétation est dense.Soil work between rows of plantations is traditionally carried out using mechanical and / or hydraulic tools, such as blade tools (sarcleuse) or plow tools (decavaillonneuses). The pivoting of these tools around an obstacle (eg a vine, a fruit tree trunk, etc.) is controlled by a stem named ceps in the agricultural field. When the tractor element advances, the rod bears against the obstacle and triggers the pivoting mechanism of the tool around the obstacle. The disadvantages of this type of operation are: (1) tillage at low speeds (1.5 to 5 km / h) to avoid damage to plantations, (2) occasional wrecking of plantations, and ( 3) the continuous release of the vine guard when the vegetation is dense.

Une alternative proposée est le travail des sols agricoles plantés par une houe à doigt. Une houe à doigt est un outil mécanique rotatif muni d'extensions (ex. : plastique, caoutchouc, fer, etc.) qui s'écartent par friction autour de l'obstacle lorsque l'élément tracteur avance (FIGURE 1). Ce type de fonctionnement autorise le travail des sols à cadence élevée (4 à 8 km/h) mais présente les inconvénients suivants : (1) faible pénétration dans les sols compactés et (2) absence de pivotement autour des obstacles ce qui occasionne des risques d'arrachement des plantations ou de détérioration de l'outil.A proposed alternative is the work of agricultural soils planted by a finger hoe. A finger hoe is a rotating mechanical tool with extensions (eg, plastic, rubber, iron, etc.) that slip apart around the obstacle as the tractor element moves forward (FIGURE 1). This type of operation allows the working of soils at a high rate (4 to 8 km / h) but has the following drawbacks: (1) low penetration in compacted soils and (2) lack of pivoting around obstacles which causes risks tearing of plantations or deterioration of the tool.

Le dispositif selon l'invention proposée remédie à ces inconvénients par modification du dispositif de la houe à doigt (FIGURE 2). Il comporte un mécanisme sur lequel peut être inséré un outil rotatif standard de travail des sols. Ce mécanisme est pourvu d'un levier articulé qui fait pivoter l'outil rotatif sur un obstacle à l'aide d'un ressort de rappel. Lorsque l'élément tracteur avance, la pression et la vibration exercées sur le ressort améliorent la pénétration de l'outil rotatif dans le sol et autorise le pivotement de ce même outil autour des obstacles. Ce type de fonctionnement s'effectue à cadence élevée (4 à 12 km/h).The device according to the proposed invention overcomes these disadvantages by modifying the device of the finger hoe (FIGURE 2). It has a mechanism on which can be inserted a standard rotating tool soil working. This mechanism is provided with an articulated lever that rotates the rotary tool on an obstacle using a return spring. As the tractive element advances, the pressure and vibration exerted on the spring improves the penetration of the rotary tool into the ground and allows the pivoting of the same tool around the obstacles. This type of operation is carried out at high speed (4 to 12 km / h).

Les dessins annexés illustrent le dispositif traditionnel de la houe à doigt (Figure 1) et la modification de ce dispositif selon l'invention proposée (Figure 2). Les flèches sur les dessins représentent le sens d'avancement de l'élément tracteur.The accompanying drawings illustrate the traditional device of the finger hoe (Figure 1) and the modification of this device according to the proposed invention (Figure 2). The arrows in the drawings represent the direction of travel of the tractor element.

En référence à la FIGURE 2, le dispositif est composé d'un support (1) présentant une butée (2) et d'une bielle (3). La bielle (3) possède deux perçages (4) : l'un pour l'articulation sur le support (4 ; perçage supérieur) et l'autre pour accrocher un outil standard de travail des sols (4 ; perçage inférieur). La bielle (3) est reliée au support par une liaison boulonnée comportant une bague d'usure, ce qui augmente la durée de vie de la bielle et du support. Un anneau soudé à l'extrémité supérieure de la bielle (3) est fixé à un ressort (5), ce qui fait pivoter la bielle (3) lorsque l'outil rencontre un obstacle.With reference to FIGURE 2, the device is composed of a support (1) having a stop (2) and a connecting rod (3). The connecting rod (3) has two holes (4): one for the articulation on the support (4, upper drilling) and the other for hooking a standard soil working tool (4, lower drilling). The rod (3) is connected to the support by a bolted connection having a wear ring, which increases the life of the rod and the support. A ring welded to the upper end of the connecting rod (3) is fixed to a spring (5), which pivots the connecting rod (3) when the tool encounters an obstacle.

La seconde extrémité du ressort (5) est attachée au support (1) à l'aide d'une tige filetée (6) traversant le support (1). La tige filetée (6) possède un anneau soudé à l'une de ses extrémités servant à la fixation du ressort (5). La tige filetée (6) est maintenue sur le support (1) grâce à un ensemble écrou / contre écrou (7) et rondelles (8). Le serrage (desserrage) de l'écrou (7) augmente (réduit) la tension du ressort, ce qui permet d'ajuster la pénétration de l'outil standard de travail des sols fixés au bout de la bielle (3) suivant la vitesse d'avancement de l'élément tracteur. Après ajustement, le réglage de la tension du ressort (5) est conservé en serrant le contre écrou (7).The second end of the spring (5) is attached to the support (1) by means of a threaded rod (6) passing through the support (1). The threaded rod (6) has a ring welded at one of its ends for fixing the spring (5). The threaded rod (6) is held on the support (1) through a nut / nut assembly (7) and washers (8). The tightening (loosening) of the nut (7) increases (reduces) the tension of the spring, which makes it possible to adjust the penetration of the standard tool for working the floors fixed at the end of the connecting rod (3) according to the speed progress of the tractor element. After adjustment, the adjustment of the spring tension (5) is maintained by tightening the lock nut (7).
