One type of spray system is known which includes an agricultural sprayer associated with a plurality of sources of spray products, generally liquid form products. This spraying system is equipped with a plurality of spray members which are each adapted to spray at least one product from different sources. Also, the system includes multi-way valves that are actuated by the operator to connect and associate one of the product sources to one of the spray members, depending on the position of the valves selected. With this type of spraying system, there is a risk of inadvertently connecting one of the product sources with a spraying device not suitable for this product. To avoid such mishandling in particular, the present invention provides a sprayer dispensing device which aims to reliably connect at least one of the product sources on the adapted spray member. To this end, the present invention relates to a dispensing device for an agricultural sprayer, the sprayer being associated with a plurality of product sources and a plurality of spray devices, characterized in that it comprises: a supply manifold having at least two inlets and at least one outlet, each inlet being adapted to be connected to one of said product sources and each inlet cooperating with a closure valve; a distribution manifold having at least one inlet and at least two outlets, each outlet being adapted to be connected to one of said spray members and each outlet cooperating with a closure valve; a distribution duct which connects the outlet of the supply manifold to the inlet of the distribution manifold; a control mechanism which comprises at least one camshaft carrying a plurality of cams; aque cam acting on the opening and closing of one of said valves, the camshaft being rotatably mounted between several angular positions in each of which the valves allow the supply of one of said spray members by at least one of said sources of products and a means for actuating the camshaft.
    [0002] Thus, the invention avoids any risk of mishandling by mechanically linking each product source to a spraying member. According to another characteristic, the control mechanism comprises a first camshaft which carries at least two cams each acting on one of said associated valves of the supply manifold, and a second camshaft which carries at least two cams each acting on a said associated valves of the supply manifold, the first shaft being rotatably connected to the second shaft by disengageable coupling means.
    [0003] This characteristic makes it possible to drive the first camshaft in rotation independently of the second camshaft, which makes it possible in particular to change the initial allocation of the product sources to the spraying members. In addition, the dispensing duct is equipped with a circulation pump designed to allow the flow of products from said sources to said spray members. According to an alternative embodiment, the supply manifold and the distribution manifold are an integral part of the circulation pump. Also, the device comprises a safety conduit which connects the supply manifold to the distribution manifold and which is equipped with a safety valve. Finally, the device comprises at least one means for regulating the flow rate of the product. Other characteristics and advantages of the invention will become apparent on reading the detailed description which follows for the understanding of which reference will be made to the appended drawings in which: FIG. 1 is a schematic view which illustrates a dispensing device for agricultural sprayer having a camshaft for controlling the valves, according to a first embodiment of the invention; FIG. 2 is a schematic view illustrating the device of FIG. 1 comprising two camshafts for controlling the valves, according to a second embodiment of the invention. For the various embodiments, the same references 5 may be used for identical elements or providing the same function, for the sake of simplification of the description. There is shown in FIG. 1 an agricultural sprayer which comprises three sources of liquid product 12a, 12b, 12c of different nature and three spray members 14a, 14b, 14c each adapted to spray at least one of the products 12a, 12b, 12c. The sprayer 10 is equipped with a dispensing device 16 that makes it possible to select a suitable combination of a product source with an associated spray member 14a, 14b, 14c, knowing that the product sources 12a, 12b, 12c are not not all compatible with each spraying member 14a, 14b, 14c. For this purpose, the distribution device 16 comprises a supply manifold 18 which is connected to the product sources 12a, 12b, 12c, and a distribution manifold 20 which is connected to the spray members 14a, 14b, 14c. The supply manifold 18 has three inputs 22a, 22b, 22c and an output 23, the inputs 22a, 22b, 22c being connected to the product sources 12a, 12b, 12c respectively. In addition, each input 22a, 22b, 22c of the supply manifold 18 cooperates with a closure valve 24a, 24b, 24c respectively. Each valve 24a, 24b, 24c has an axial operating rod 26a, 26b, 26c which is provided with a head 28a, 28b, 28c at one end, and a foot 30a, 30b, 30c at a second. opposite end, respectively. The stem 26a, 26b, 26c of each valve 24a, 24b, 24c is axially slidably mounted on the body of the supply manifold 18, so that each valve 24a, 24b, 24c is movably mounted between an open position in which the head 28a, 28b, 28c allows the passage of the product 12a, 12b, 12c of the associated source through the associated inlet 22a, 22b, 22c of the supply manifold 18, and a closed position in which the head 28a, 28b , 28c obstructs the input 22a, 22b, 22c.
    [0004] Similarly, the distribution manifold 20 has an inlet 30 and three outlets 32a, 32b, 32c, the outlets being connected to the spraying members 14a, 14b, 14c respectively. In addition, each outlet 32a, 32b, 32c of the distribution manifold 5 cooperates with a closure valve 34a, 34b, 34c respectively. Each valve 34a, 34b, 34c comprises an axial actuating rod 36a, 36b, 36c which is provided with a head 38a, 38b, 38c at one end and a foot 40a, 40b, 40c at a second end. opposite, respectively. The stem 36a, 36b, 36c of each valve 34a, 34b, 34c is slidably mounted axially on the body of the distribution manifold 20, so that each valve 34a, 34b, 34c is movably mounted between an open position in which the head 38a, 38b, 38c allows the passage of the product through the outlet 32a, 32b, 32c of the distribution manifold 20, and a closed position in which the head 38a, 38b, 38c obstructs the outlet 32a, 32b, 32c. Complementarily, a distribution duct 42 connects the outlet 23 of the supply manifold 18 to the inlet 30 of the distribution manifold 20, to allow the products to pass from one to the other. Also, the dispensing device 16 is equipped with a control mechanism 44 which is adapted to drive the various valves in motion to combine and connect a product source with a suitable spray member. According to a first embodiment of the invention, represented in FIG. 1, the control mechanism 44 comprises a camshaft 46 which carries six cams 48. Each cam 48 cooperates with the foot of a valve 24a, 24b, 24c, 34a, 34b, 34c associated, for driving the associated valve in its open or closed position. In addition, the camshaft 46 is rotatably mounted between at least three angular positions in each of which the valves allow the supply of one of the spraying members 14a, 14b, 14c by one of the product sources 12a, 12b, 12c. For this purpose, the three cams 48 which are associated with the three valves 24a, 24b, 24c of the supply manifold 18 are arranged on the camshaft 46 in an angularly offset manner by at least one third of a turn, ie 120 degrees of angle, according to the three angular positions of the camshaft 46. Similarly, the three cams 48 which are associated with the three valves 34a, 34b, 34c of the distribution manifold 20 are arranged on the camshaft 46 angularly offset by at least one third of a turn, ie 120 degrees of angle, according to the three angular positions of the camshaft 46. More particularly, the cams 48 are arranged so that for each angular position of the cam camshaft 46, one of the three valves 24a, 24b, 24c of the supply manifold 18 is open and one of the three valves 34a, 34b, 34c of the distribution manifold 20 is open, to allow the passage of the product from one of the product sources 12a, 12b, 12c, up to one of the spraying members 14a, 14b, 14c associated. In addition, the dispensing device comprises an actuating means 50 for driving in rotation the camshaft 46, the actuating means 50 is according to the example described here a crank which is connected to the shaft with cams 46 for driving the camshaft 46 manually between its three positions. Non-limitingly, the actuating means 50 may also be motorized means, for example an electric motor which drives the camshaft 46 in rotation. As can be seen in Figure 1, the flow of the products 12a, 12b, 12c from their source to the spraying members 14a, 14b, 14c is provided by a circulation pump 52 which is mounted on the conduit 42. According to an alternative embodiment of the invention not shown, the supply manifold 18 and the distribution manifold 20 are an integral part of the circulation pump 52. According to another aspect of the invention, the device distribution 16 16 comprises a safety conduit 54 which connects the supply manifold 18 on the distribution manifold 20 and which is equipped with a safety valve 56, to limit the pressure and protect the device. In addition, a control means 58 of the product flow rate is associated with a spraying member 14c. According to a second embodiment of the invention, shown in FIG. 2, the control mechanism 44 comprises a first camshaft 46a which carries three cams 48 each cooperating with one of the three valves 24a, 24b, 24c of the collector. 18, and a second camshaft 46b which carries three cams 48 each cooperating with one of the three valves 34a, 34b, 34c of the distribution manifold 20.
    [0005] The second embodiment of the invention being similar to the first embodiment, it will be described only briefly so as not to unnecessarily burden the description. According to this second embodiment, each camshaft 46a, 46b is rotatably mounted between at least three angular positions in each of which the valves allow the feeding of one of the spraying members 14a, 14b, 14c by one of the sources of products 12a, 12b, 12c. In addition, the first camshaft 46a is rotatably connected to the second camshaft 46b by a disengageable coupling means 60. The coupling means 60 consists, for example, of a pinion gear 62 which is free to move in translation on the first camshaft 46a between an engaged engagement position of the second camshaft 46b and a disengaged position. This characteristic allows, when the coupling means 60 is disengaged, to rotate the first camshaft 46a 20 independently of the second camshaft 46b, which allows in particular to change the initial allocation of the product sources 12a, 12b, 12c to the spraying members 14a, 14b, 14c. The present description of the invention is given by way of non-limiting example.
    [0006] Likewise, simple mechanical inversions are covered by the invention as well as the number of sources of products and sputtering members. It will be understood that the valves may be replaced by any equivalent means for opening or closing an orifice such as a valve or valve.
