Definitions

  • the present invention relates to improvements made to liquid spreading devices and more particularly, although not exclusively, to those installed on the boom of a spraying apparatus for the purpose of projecting fillets of liquid loaded with fertilizer onto the ground. .
  • the subject of the present invention is a device for spreading liquid in the form of threads which can be added to a conventional nozzle, without transformation of the latter.
  • the nozzles in question which are mainly produced in three different forms, are assembled to a threaded nozzle holder by means of a wing nut which acts on a flange. This nut presses against the end of the nozzle holder, either a pellet having a central perforation, or an element generating a helical movement of the liquid, or even a slot nozzle for producing a flat jet.
  • means are associated with the outlet from one of the above three nozzles for reducing the pressure of the jet in order to transform it into at least one liquid stream. It is understood that it is first necessary to reduce the pressure, then pass the liquid through an orifice long enough so that no spraying takes place at its outlet in the atmosphere. Firstly, a throttle valve is used, placed immediately at the outlet of the nozzle, its bore opening into an expansion chamber; there is then provided a thick transverse wall intended to close said chamber.
  • a spreading ramp 1 in the form of a pipe in which a pressurized liquid is sent.
  • the ramp is provided with a number of nozzles 2 which generate a jet of sprayed liquid, for example by means of a slit nozzle as will be better explained below.
  • a device according to the invention referenced 3 intended for the production of three threads 4, 5, 6 ending in parallel planting lines after having traversed a path of the parabolic kind whose direction is perpendicular to the ground at the end of this path. This avoids variations in the spacing of the outer threads 4 and 6 in the event of different ramp heights.
  • Each of the nozzles 2 is composed of a threaded end piece 7 (fig. 2) integral with the ramp 1 and whose bore 7a communicates with that of this ramp.
  • a slot nozzle 8 is pressed by its flange 8a against the end of the end piece 7.
  • the upper face of this flange is provided with two lugs 8b intended to engage in longitudinal grooves 7b formed in bore 7a. So thanks to the orientation of these grooves the slot of the nozzle is oriented in the desired direction, for example parallel to the geometric axis of the ramp 1.
  • This assembly which is well known in the art, will not be described further of the flange 8a being effected by means of a wing nut such as that 9 shown in FIG. 2 and provided with a shoulder 9a which comes to bear against the underside of the collar 8a.
  • a stepped sleeve 10 with two bores, one upper 10a surrounding the nozzle while the other 10b of smaller diameter determines with the first an annular part 10c .
  • the bottom of the sleeve 10 is closed by a thick transverse partition 10d.
  • a throttle 11 provided with a peripheral collar lla which bears against the annular face 10c of this sleeve.
  • This throttle further comprises a central bore 11b whose diameter is determined so that the pressure of the liquid leaving the nozzle is greatly reduced.
  • the length of the choke 11 is less than the depth of the bore 10b of the sleeve 10 so as to determine at the bottom of the latter an expansion chamber 12.
  • the wall 10d is crossed by a central orifice 13 and by two others oriented obliquely and that have been referenced respectively 14 and 15. Said orifices give rise respectively to threads 5, 4 and 6. It will be noted that said orifices are located in the same diametrical plane of the wall 10d.
  • the sleeve 10 is pressed against the collar 8a of the nozzle 8 by means of the shoulder 9a of the nut which comes to bear under an annular flange 10f formed at the periphery of this sleeve.
