Definitions

  • the present invention relates to a portable liquid sprayer, in particular for the treatment of vegetation.
  • the treatment of vegetation by spraying liquid is usually done, in the case of small areas or difficult routes, using portable sprayers, comprising a container which can be carried on the back of the operator and is capable of containing the suitable liquid, a lance connected to the container by a flexible conduit, and means for pressurizing the liquid from the container and sending it through the conduit to the lance.
  • portable sprayers comprising a container which can be carried on the back of the operator and is capable of containing the suitable liquid, a lance connected to the container by a flexible conduit, and means for pressurizing the liquid from the container and sending it through the conduit to the lance.
  • the simplest and most economical model includes a sealed tank, fitted with a hand pump, which can be a simple piston pump, and which pressurizes the air contained in the tank above the level some cash.
  • a hand pump which can be a simple piston pump, and which pressurizes the air contained in the tank above the level some cash.
  • the operator after putting the tank under pressure, sprays liquid through the lance until the pressure has dropped to an insufficient level. It then suffices to reactivate the pump to continue operating.
  • a more sophisticated, and therefore more expensive, model includes a liquid pump placed between the container and the conduit, and actuated by an electric motor. This pump takes liquid from the container, pressurizes it and sends it through the pipe to the lance. The tank therefore does not have to be sealed.
  • the electric motor can be powered either by a flexible conductor or by an autonomous energy source such as batteries or accumulators recharea wheat.
  • a first object of the invention is to provide a system which allows traders to keep in stock the two types of sprayers for a total size smaller than that to which current practice leads.
  • a second object of the invention is to provide a sprayer having a lower cost price compared to current techniques, while retaining a good presentation.
  • the invention provides a sprayer comprising a container capable of containing a liquid, a lance connected to the container by a flexible conduit, and removable means for putting the liquid in the container under pressure and sending it into the conduit, this sprayer having the following features: - Two means are provided for pressurizing the liquid and sending it into the conduit, these means being able to be alternated one in place of the other, one of the means comprising a hand pump capable of pressurize the interior of the container, and means for sealingly sealing this pump in the container, while the other means comprises an electric pump capable of taking the liquid from the container and sending it under pressure into the liquid, and means for fixing this pump in the container, - the tank is capable of withstanding the pressure generated by the hand pump.
  • the electric pump carries an electric motor with rechargeable batteries or accumulators.
  • the trader no longer has to keep in stock more than one set of tanks corresponding to the different capacities provided, and sets of hand pumps or electric pumps, interchangeable , of much smaller volume.
  • the saving on the necessary storage capacity is therefore around 50%.
  • the container associated with a hand pump comprises, in addition to an orifice into which the hand pump is inserted, a pressure gauge or a venting valve and sometimes a second filling orifice closable by a tight plug.
  • the pressure gauge or the venting valve are mounted on the plug of the filling orifice.
  • it is associated with the hand pump a plug capable of sealing and equipped with a pressure gauge or a venting valve, while it is associated with the pump. electric plug without a pressure gauge and vent valve, and preferably having a vent to allow air to enter the tank.
  • the cost price of the assembly comprising the electric pump is reduced by the fact that the corresponding filling plug can be of a very reduced price. Moving from one version to another is easy, however.
  • the assembly comprising a hand pump can however be improved from the point of view of safety by providing that the plug associated with the hand pump is a screwed plug and comprises a venting valve and means so that this valve must be actuated before unscrewing the cap.
  • said venting valve comprises a piston loaded by spring and moving in a cylinder opening in the lower part into the interior of the container and having in the upper part a widening of the atmosphere, and the cap is provided with a cap which surrounds it and which is connected to the cap by a helical cam, the cap being provided with means for moving said piston upwards, so that, if the cap is turned in the unscrewing direction, it raises d 'first the piston for venting before driving the cap for its unscrewing.
  • said venting valve comprises a piston loaded by spring and moving in a cylinder opening in the lower part inside the container. and having, in the same lower part, a widening for its venting, the piston rod carrying a cap which covers a large part of the upper surface, and the cap is a screw cap, which requires, to be unscrewed , that is exerted on him, first, a significant downward force, this force can only be exerted by pressing on the cap of the valve stem, which causes the atmosphere to be placed in the container.
  • the piston rod is a molded part, whose cross section has an outer contour of circular shape, and which has two or more parallel longitudinal grooves between them, of sufficient depth to exceed the axial plane perpendicular to their transverse direction.
  • FIG. 1 shows a tank 1, with a lower tank 2 made of transparent plastic, on which is welded an upper part 3, made of more rigid plastic, which carries two orifices 4 and 5, each provided with an internal thread, either outside, indifferently.
  • FIG. 2 shows a schematic section of the hand pump in its preferred form.
  • a base 6, provided with a thread, is intended to be mounted in the hole 5. It carries on the one hand the cylinder 7 of the hand pump and, on the other hand, the outlet 8 of a tube 9 d evacuation of the liquid.
  • This outlet 8 has a nozzle 10 for connection with the flexible conduit 11 which leads to the ramp 12, terminated by a nozzle 13.
  • the other end of the conduit 9 comprises a filter 14.
  • an expulsion valve At the lower end of the cy lindre 7 of the pump, there is shown at 15 an expulsion valve.
  • the piston 16 of the pump is connected by a rod 17 to a handle 18 which is used for its actuation in the vertical direction.
  • FIG. 3 shows the section through the preferred shape of the electric pump.
  • the casing 20 carries, at its lower end, a filter 25 placed on the supply of the pump. This filter is optional.
  • the outlet of the pump is connected by a conduit 26 to a connector 27 identical to the connector 10 in FIG. 2.
  • a handle 28 is mounted on the upper end of the casing 20. It is used only for handling. There is shown at 29 and 30, respectively, a motor control switch 23 (which may possibly be carried by the handle 28), and a socket for connecting the charger 21 to the sector, for recharging the accumulators 22.
  • the electric pump is fixed in the tank 1 by means of a nut which is screwed onto the thread of the collar.
  • This nut can be integral with the pump or independent.
  • Figures 4 to 6 show a plug 31, intended to close the loading hole 4 of the tank in the case of the "hand pump” version.
  • An inner plug 32 is screwed onto a thread 33 surrounding the hole 4.
  • a seal 34 is placed between the inner plug 32 and the edge of the hole 4.
  • the central part of the inner plug 32 has an axial bore in three successive parts : an inner part 35 of small diameter, an intermediate part 36 of larger diameter, and an outer part 37 of even larger diameter.
  • a piston 38 can move in the bore. Its diameter is such that it cannot penetrate into the narrow part 35, that it flows without play, and forms a seal in the intermediate part 36, and that it gives free passage to air in the widened part 37.
  • a compression spring 39 held by a nut 40 pushes the piston 38 downwards.
  • the rod 41 of the piston carries a cap 42 whose utility will be explained below.
  • the inner plug 32 is covered by an outer plug 43, the connection between the two plugs being made by a helical screw 44 which extends over approximately a quarter of a turn.
  • the upper part of the plug 43 is flat, it has a recess in its central part, this recess having a diameter slightly greater than that of the cap 42.
  • FIG. 5 shows the situation when the reservoir is under pressure: the pressure of the reservoir acts on the piston 38 against the spring 39 and raises the latter, as well as the cap 42 which is attached to it, so good that ci protrudes above the upper surface of the outer cap 43. Graduations 45 traced on the lateral face of the cap 42 make it possible to judge the degree of lifting thereof, and therefore to know the pressure inside the tank. If this pressure becomes such that the piston 39 reaches part 37 of large diameter of the bore, the seal being no longer ensured, the air escapes. So there is a safety valve, or if you want, a pressure relief valve.
  • FIG. 6 shows how the tank is decompressed before opening.
  • the rotation of the outer plug 43 on the inner plug 32 produces, due to the helical screw 44, a lifting of the outer plug relative to the inner plug.
  • the outer plug has, on the sides of the cavity which receives the cap 42, a flange 46, which passes under the cap 42, and lifts it up, thus driving the piston 38 until it reaches the part of large diameter 37 of the bore. At this time, the interior of the tank is vented, and therefore, any overpressure disappears.
  • the end of the helical screw 44 is reached, and from this moment, the inner plug 32 is driven, thereby causing it to be unscrewed.
  • Figures 7 to 9 show a variant of the arrangement of Figures 4 to 6.
  • the same references representing the similar elements.
  • the internal plug 32 is kept more or less identical, however, in the bore, the part of smaller diameter 36 is replaced by a part of large diameter 47, that is to say that the bore comprises, from bottom to top, a large diameter part 47, a smaller diameter part 36, this diameter corresponding to that of the piston 38, and again a large diameter part 37.
  • the piston 38 is held in the rest position , in the relatively small diameter portion 36, thanks to the action of two opposing springs 39 and 48 which act on its two sides.
  • the cap 42 has, at its upper part, a flange 49, of large diameter, which extends above the upper part of the plug 32.
  • FIG. 10 shows the plug 49 which is used in the "electric pump” version. As we can see, it is a stopper whose external shape is similar to that of the inner stopper 32 described above, but there are no bores with several diameters, no pistons, no caps. simply represented at 50 a vent hole. Of course, a seal such as 34 is unnecessary here. We can see that this is an extremely inexpensive piece.
  • Figure 11 is a cross section of the piston rod 17 of the hand pump.
  • This section is derived from a solid circular shape by the fact that there are two wide and deep longitudinal grooves 60, 61 which deeply cut the rod. These grooves are, in section, with parallel sides, if one neglects the bodies necessary for the molding process. The sides of these grooves are mutually parallel, and therefore parallel to a median plane 62 of the section. They extend well beyond the axial plane 63 perpendicular to the plane 62, and stop only at a distance e from the opposite side of the periphery of the section.
  • the distance between the two grooves is also equal to this distance e , and the width of the grooves is calculated so that the same distance e is found between the groove and the end of the corresponding perpendicular diameter.
  • a general S-shape is thus obtained with a substantially constant section of material.
  • the outlet of the two grooves, taken together corresponds approximately to a quarter of the periphery of the section. This shape ensures great lightness, for good resistance mechanical, and at the same time effective guidance because practically three-quarters of the circular periphery of the rod are retained. If we want to describe more precisely the shape of the cut, we can consider that it has a central core 64, with parallel faces, ert substantially parallel to the plane 62.
  • the two faces of the core 64 make with the plane 62 an angle equal to the draft angle, for example 1 degree.
  • the central core is connected, at each of its ends, to a part 65, forming an arc of a circle of 90 degrees, and of thickness e equal to that of the central core.
  • Each part 65 is extended by an end part 66, bounded on one side by an arc of a circle which forms the periphery of the rod, and on the other side by a flat surface forming the side of the slot 60 or 61 which is opposite the central core 64.
  • This terminal part the thickness of which is therefore decreasing, extends over approximately 45 degrees, and ends in a rounded radius.
  • FIG. 12 shows a variant of the embodiment of FIG. 11, in which there are three grooves, 67, 68 and 69, the grooves 67 and 68 being arranged symmetrically on either side of a plane of symmetry 70, and the groove 69 being, for its part, coaxial with said plane 69.
  • Figure 13 relates to another variant, in which there are, this time, four grooves 71, 72, 73 and 74, mutually parallel and alternately opening in opposite directions.
  • the principles of design and construction described in connection with FIG. 11 are also valid for FIGS. 12 and 13.
