Definitions

  • This invention relates to a spraying assembly which is suitable for market garden spraying, and agricultural row crops such as cotton.
  • the Applicant herein has identified a need to combat the overspray problem which exists, wherein for example a row of cabbages could be destroyed if weedicide sprayed between that and an adjacent row was carried by the wind or other means from the target area to the cabbages, or vice versa, the weeds between the rows of cabbages could benefit from overspray of fertiliser. It is common practice to produce a spray which has small sized droplets, even into the micron range, and this spray is very susceptible to any air movement which will cause drift of the spray. Even forward movement of the vehicle on which the spraying apparatus is mounted will cause air movements around the spray head and cause drift or movement of the spray outside the desired area. Applicant has also identified a need to have adjustment means so that the spacing between the sprays can match the rows of plants, and also the width of the spray pattern can be varied, some rows of plants requiring much wider spray patterns than others.
  • a plurality of transversely spaced spray hoods each having an aspect ratio when viewed in plan of at least 3, each being carried by clamp means to a bar arranged to be secured to a vehicle and each being rotatable so that the narrow dimension can be either orientated to the direction of travel to produce a narrow spray pattern, or can be orientated to present any variation of width up to the wide dimension to provide a wide spray pattern.
  • a spraying assembly comprising at least one spray head, each spray head comprising a spray nozzle with a spray hood, each spray hood having an aspect ratio of at least 3, clamp means attaching each said hood to a vehicle such that each hood can be orientated relative to the direction of travel of the vehicle to provide either a wide or narrow spray width, whereby each hood protects the spray from the influence of wind or air movements.
  • a spraying assembly comprising at least one spray unit mounted in a hood, said hood having an aspect ratio of at least 3, said spray unit delivering a discoid shaped spray pattern and being mounted in a major wall of the hood whereby the spray pattern does not contact the interior surface of the hood to any extent, the hood protecting the spray pattern from the effect of any air movement or wind.
  • Fig 1 is a view of the spray assembly attached to a vehicle
  • Fig 2 is a cross-sectional view along the lines 2-2 of Fig. 1 ;
  • Fig 3 is a side elevation of the portion show in Fig. 2;
  • Fig 4 is an illustration of the spray pattern within a hood
  • Figs 5, 6 and 7 are illustrations of the various positions of the spray heads.
  • Fig 8 is another embodiments of the invention.
  • a motor vehicle 10 is shown in Fig 1 and is of the type commonly used by market gardeners, being provided with a mounting frame 11 , the mounting frame 11 having attached to it a transverse bar 12, which in this embodiment is of square tube cross-sectional shape as illustrated in Fig 2, the transverse bar 12 being attached to mounting frame 11 by means of a mounting bar 13 which is illustrated only in fragmentary end elevation in Fig 2, the transverse bar 12 and the mounting bar 13 being welded together.
  • Fig 3 does not illustrate the transverse bar 12 but it merely serves to illustrate the clamping arrangement for vertical suspension bar 15.
  • Vertical suspension bars 15 each carry a spray head 16, the spray head 16 comprising a spray unit 16(a )contained within a hood 17.
  • the hood 17 contains the nozzle which is fed from a hose 18 (Fig 1 ) and the lower end of hood 17 terminates in a peripheral skirt 20 as shown in Fig 1.
  • the spray unit used is preferably a so-called "constant drop applicator" wherein droplet size lies mostly in a small range of sizes, and has a horizontal axis of rotation. The curvature of the hood is sufficient that most droplets will fall to the open mouth of the hood without being intercepted by the hood.
  • the spray unit delivers a spray pattern which is generally of vertical discoid shape, whereby the droplets fall to the target area in a hood having a shape that it has an aspect ratio of at least 3.
  • the spray unit is positioned in the hood in a position such that in operation the spray droplets do not contact the sides or walls of the hood but fall from the lower end of the hood. In this way all of the spray may be in the small or micron sized droplet form for most effective coverage. If the spray contacted the wall of the hood, then large ineffective sized drops of the spray material would fall from the lower edge of the hood thus not giving effective coverage and also wasting spray material.
  • the aspect ratio of 3 is a preferred ratio, but it will be realised that this can vary depending on the type of spray unit used.
  • the spray unit delivers a spray pattern which is discoid in shape and if it has a greater or lesser thickness in relation to the diameter of the spray pattern, then the aspect ratio of the hood can vary, it being a requirement that the hood be matched to the discoid spray pattern produced by the spray unit such that the spray produced does not contact the internal walls of the hood.
  • the aspect ratio be at least 3, it is to be realised that the invention is not to be limited thereto.
  • each vertical suspension bar 15 is of circular cross-sectional shape, and is firmly clamped to bar 12 by means of saddles 21 , such that the rotational position and height of each hood 17 can be adjusted.
  • the width of a spray pattern can be varied by rotating the hoods 17 about their respective vertical axes and the maximum width of a spray pattern can be equal to or even slightly greater than the width of the hood 17 if the hood 17 lies in the same direction as the transverse bar 12.
  • width W2 being the width of the spray pattern in the illustrated embodiment, but this can be reduced down to width W3 by rotation of the respective hoods 17 about their vertical axes, until the narrow widths of hoods 17 is presented in the direction of travel.
  • the width W2 is an intermediate width which can of course be varied by rotation of the hoods.
  • each spray head is mounted by a parallel motion linkage 20 to the bar 12.
  • Each spray head thus trails behind the bar, and includes a wheel 21 supporting the spray head, so the spray head is self levelling as it passes over uneven ground.
  • U-shaped locating strips 33 locate the bolts 24, and the front flanges 34 extend across the outer surface of the front wall 35 of transverse bar 12.
  • the flanges of saddles 21 then bear against the front flanges 34 of the locating strips 33 to thereby clamp the flanges firmly against those strips and at the same time clamp portion of the surface of each respective transverse bar 12 against the front wall 35.
  • the hoods effectively shield the spray from any undesirable air currents, such as wind or that caused by the forward movement of the vehicle on which the spray assembly is mounted.
  • the number of spray heads 16 is indefinite and can be extended from the three shown up to say twenty in some cases.
  • the height and orientation of the spray hoods 17, and the spacings are all readily variable to position the hoods where required, and in some instances both weedicide and fertiliser can be sprayed in a single pass of the vehicle 10 between row crops.

Abstract

Système de pulvérisation conçu pour l'arrosage de jardins maraîchers et comprenant plusieurs têtes de pulvérisation (16) dont chacune contient une buse de pulvérisation, recouverte d'une cloche (17); vue d'en haut, chaque cloche de pulvérisation (17) possède un rapport de forme égal ou supérieur à 3. Les têtes (16) sont montées sur un véhicule (10) de manière à pouvoir être réglées et orientées par rapport au sens du mouvement dudit véhicule (10) pour modifier la largeur de couverture de chaque tête (16). La buse de pulvérisation est montée sur une paroi principale de la cloche (17) de façon que la bouillie de pulvérisation n'entre pas en contact avec la surface intérieure de la cloche (17); la cloche (17) permet de réduire au minimum la formation d'embruns de pulvérisation en protégeant la bouillie de pulvérisation contre le vent et les courants d'air.
