VINE TREATMENT DEVICE WITH SPRAY CELL FIXED TO TRACTOR AND TANK
DETACHABLE ROLLER.

 The present invention relates to a spray treatment device attachable to a self-propelled vehicle of the tractor type, in particular for the treatment of the vine.

A device of the prior art represented in FIG. 1, comprises a spraying cell and a reservoir carried by the same chassis rolling on two wheels and coupled to the coupling device of a towing vehicle.

 The spraying cell comprises a turbine and means for supplying treatment product contained in the reservoir which are actuated by a shaft connected to the power take-off of the towing vehicle.

 The spraying cell also comprises spraying means which can be either ramps perpendicular to the axis of the chassis, or a protective barrel which can be oscillating, or a system with several outputs.

The problem lies in the principle of realization of the coupling, coupling between spraying device and towing vehicle. In fact, to be able to turn or maneuver, the shaft must be uncoupled in order to avoid breakage of its end gimbals.

 The invention solves this problem by proposing a spraying device of the above type, characterized in that the spraying cell is detached from the tank, said cell being fixed to a support structure which is itself fixed to the rear of the towing vehicle. , while the tank is carried by a movable or detachable chassis of the carrying structure by means of a coupling means provided at the rear of the carrying structure.

 More particularly, the carrying structure comprises two low attachments and a high attachment which can be joined to the three-point hydraulic coupling of the towing vehicle.

The invention will be better understood using the description below, given with reference to the following appended figures: - Figure 1: side view of a mobile spraying device of the prior art coupled to a tractor vehicle, - Figure 2: side view of a mobile spraying device according to the invention coupled to a tractor vehicle, - Figure 3: general view of a spraying cell according to the invention, without its spraying means.

 To solve the problem of the prior art, the inventive idea consisted in going against the habits according to which all the elements constituting the spraying device were carried by the same rolling chassis, and consisted in separating the chassis and tank spray cell.

 According to FIGS. 2 and 3, given by way of nonlimiting example of the invention, the spraying cell 1 is fixed on a carrying metallic structure 7, itself integral with the hydraulic coupling at three points (two low points Sa, 8b and 1 high point 8c) of the towing vehicle, by two low fasteners 9a, 9b, and a high fastener 9c.

The embodiment of the supporting structure 7 can have different shapes such as for example that of FIG. 3 which mainly comprises: - a horizontal lower frame 7a serving to support the various elements of the spraying cell 1 including the turbine 10, and both side rails each carry at their front end a fastener 9b, 9a, the spacing between the two fasteners 9a, 9b

<Desc / Clms Page number 3>

 corresponding to the spacing between the two low hydraulic coupling points 8a and 8b.

 - Two rear uprights 7b partially shown and on which spraying means 6 can be fixed (not shown in Figure 3 but visible in Figure 2).

 - a frame structure 7c of the turbine 10, - a front structure 7d for positioning the upper attachment 9c opposite the high point 8c of the hydraulic coupling of the towing vehicle.

We also provide: - on the supporting structure 7, a mechanical transmission assembly
11 allowing the connection to the shaft 5 connected to the power take-off of the towing vehicle and allowing the transmission of the movement to the turbine 10 by system of returns and belts; - And at the rear of the frame 7a of the structure 7, a coupling means 12 for a rolling trailer, for example of the ball-hitch caravan type.

According to the invention, the spray cell 1 is secured to the rear of the tractor vehicle 4 by fixing its three fasteners 9a, 9b, 9c to the three coupling points 9a, 9b, 9c of the vehicle, while the tank 2 carried by a rolling chassis or a rolling trailer 13 can be hitched or unhitched from the spraying cell by means of a coupling means 12.

- le réservoir peut être utilisé seul pour d'autres applications, - le dispositif de pulvérisation dans son ensemble est plus maniable que ceux de l'art antérieur notamment lorsqu'il faut tourner en bout de rang de vigne, With a cell and tank device separable according to the principle of the invention, the following advantages are obtained:

the tank can be used alone for other applications, the spraying device as a whole is more manageable than those of the prior art, in particular when it is necessary to turn at the end of the vine row,

<Desc / Clms Page number 4>

- il n'est pas nécessaire de désaccoupler l'arbre 5 pour manoeuvrer puisque la cellule de pulvérisation reste dans l'axe du tracteur et que l'articulation se fait au niveau du moyen d'attelage 12 et les risques de casse de cardans n'existent plus.

- It is not necessary to uncouple the shaft 5 to maneuver since the spray cell remains in the axis of the tractor and that the articulation is made at the level of the coupling means 12 and the risks of cardan breakage n 'no longer exist.
