    • Grower experience, with poor disease control of grape vines, has suggested that, despite overspraying, actual spray coverage was poor, failing to penetrate the dense outer foliage, so that parts of the tree, particularly the top, were inadequately sprayed. Consequently, there was a requirement to ensure that spraying materials were deposited more efficiently and effectively upon targeted foliage, thereby reducing the volume of liquid carrier and therefore the amount of chemical required for a particular crop. This problem has been overcome by directing two fan-driven spray units (14) upward and into the foliage canopy, so as to displace the leaves in upward and outward directions, in co-operation with at least one further spray unit (16) downwardly directed, so as to spray into and partly through the canopy. The spray units are mounted on an inverted U-frame (21), which in turn is mounted on a mobile chassis or tractor (10) for transport through the crop area. For preference, two upper spray units (16) are employed, with a further option for a fifth spray unit (17), adjacent the apex (22) of the inverted U-frame (21). Multiple frames (21) may also be exploited, by suspension from an overhead boom (12). The operation is enhanced by automatic sensing and control, regulating the distance of the spray units (15, 16, 17) from the canopy, adjusting the spray rate to the canopy volume, the surface area of the leaves and produce, careful adjustment of the positions and directions of the spray units (15, 16, 17), and relating the speed of the spraying equipment to the volume of liquid sprayed. Liquids sprayed include insecticides, herbicides, oils and fertilisers.

    • An apparatus for independent voltage, air pressure, and/or fluid pressure control of multiple material or coating applicators, such as paint spray guns (16), includes a multiple gun control board (11) that allows a single power supply (10) to provide voltage to a plurality of paint guns and an independent gun control board that can output a different voltage signal for each gun to generate different gun operating voltages, different air pressures, and/or different fluid pressures. The independent gun control board includes a separate relay and potentiometer (32) for each gun to be controlled. The potentiometer (32) is adjustable so that the output voltage of the independent gun control board can be varied. The output voltage can be used to control the paint spray gun operating voltage and/or be sent to a pressure transducer to adjust the air and/or fluid pressure at which the triggered gun operates. The present invention therefore allows independent voltage and/or pressure control of each gun without requiring each gun to have its own separate power supply and pressure regulator, greatly reducing space and the number of components needed to operate multiple guns.
    • 为独立的电压,空气压力,和/或多个材料或涂层施用器,:如油漆喷枪(16)的流体压力控制的装置包括多枪控制基板(11)做了允许一个单一的电源(10),以 提供电压到喷漆枪的多个部分并加以独立的喷枪控制电路板那样可输出用于每个枪产生不同的枪的工作电压,不同的空气压力,和/或不同的流体压力不同的电压信号。 独立喷枪控制电路板包括用于将被控制各喷枪一个单独的继电器和电位器(32)。 电位计(32)是可调节的,从而没有独立的喷枪控制电路板的输出电压可以变化。 输出电压可用于控制所述喷漆枪的工作电压和/或被发送到一个压力换能器,以调节其中的枪触发操作的空气和/或流体压力。 因此,本发明允许独立的电压和/或每个枪的压力控制,而不需要每个枪具有其自己的单独的电源和调压,大大减少空间和操作多个枪所需的部件的数量。
