Description

Изобретение относитс к области распылени жидких дохимикатов в сельском хоз йстве и может быть использовано в наземных и авиационных опрыскивател х ,The invention relates to the field of spraying of liquid dochemicals in agriculture and can be used in land and aerial sprayers,

Целью изобретени вл етс снижение пусковых нагрузок и повышение качества распьта.The aim of the invention is to reduce the starting load and improve the quality of the drive.

На фиг, 1 - 3 схематически изображен механизм подачи жидкости во вращающийс распылитель соответственно при закрытом, промежуточном и полностью открытом положени х клапана; на фиг, 4 - разрез А-А на фиг. 3.Figures 1 to 3 schematically depict the mechanism for supplying a liquid to a rotating atomizer, respectively, with the valve closed, intermediate and fully open; FIG. 4 is a section A-A in FIG. 3

Механизм подачи жидкости во вра- щаюпщйс распылитель состоит из размещенной в приемной камере 1 распылител полой оси 2, в выходном центральном отверстии 3 которой размещен клапан 4, прикрепленный к штоку 5 управлени . За клапаном 4, на штоке управлени 5 размещён и закреплен к последнему наконечник 6, посадочной поверхностью 7 установленный на наружной поверхности полой оси 2 с возможностью осевых перемещений, В посадочной поверхности 7 выполнено несколько , например, два, сквозных отверсти 8 и 9 в виде пазов, размер максимального из которых в осевом направлении не превьш1ает ход штока 5, причем при открытом клапане 4, т.е. при максимально выдвинутом штоке 5, ближние к выходному отверстию 3 попаном 4 полой оси 2 полость не сооб щаетс с полостью приемной камеры. После некоторого перемещени штока вместе с ним перемещаетс наконечни 6, приоткрыва большее из отверсти 8, сквозь которое жидкость начинает поступать в приемную камеру 1, Даль нейшее перемещение штока приводитThe mechanism for supplying fluid to the rotational sprayer consists of a hollow shaft 2 placed in the receiving chamber 1 of the sprayer, in the output central opening 3 of which a valve 4 is attached to the control rod 5. Behind the valve 4, on the control rod 5, the tip 6 is placed and fixed to the last, the mounting surface 7 mounted on the outer surface of the hollow axis 2 with the possibility of axial displacements. There are several, for example, two mounting holes 7 and 9 through holes in the seating surface 7 , the size of the maximum of which in the axial direction does not exceed the stroke of the rod 5, and with the valve 4 open, i.e. With the maximum stem 5 extended, the cavity closest to the outlet 3 popana 4 of the hollow axis 2 does not communicate with the cavity of the receiving chamber. After some movement of the rod, the tips 6 move with it, slightly opening the larger of the hole 8 through which the liquid begins to flow into the receiving chamber 1. Further movement of the rod leads

Claims

1. The mechanism of fluid supply

rotating sprayer including a hollow hollow placed in the receiving chamber

the axis, in the central outlet of which a valve is mounted, connected to the control rod, is located. the fact that, in order to reduce the starting loads and to improve the quality of the spray, by uniformly distributing the liquid

axle 2, the edges of the holes 8 and 9 are equal to the length of the working body of the sprayer.

2 from the end 10 of the axis. One of the holes (for example, the hole 8) is longer than the hole 9. In the area of the holes 8 and 9, the tip 6 is provided with baffle plates 11, inclined sideways. on the walls of the receiving chamber 1 and directed to the zone of location in the latter of the bypass openings feeding directly the spraying working bodies of the sprayer.

During operation, when the stem 5 is advanced, an annular gap is created between the valve 4 and the end face 10 of the hollow axis, into which fluid flows. At the initial moment, the cavity formed by the walls of the tip 6, the end face 10 and the valve 4 of the hollow axis 2 does not communicate with the cavity of the receiving chamber. After some movement of the rod, the tip 6 moves along with it, slightly opening the larger of the holes 8, through which the liquid begins to flow into the receiving chamber 1. Further movement of the rod leads

first, to increase the supply by increasing the flow area of the hole 8, and then to the accelerated growth of the supply due to the joint operation of both holes 8 and 9, Escaping from the last jet, hitting the reflective plates 11, change the path of movement and, being directed obliquely into side of the walls of the receiving chamber, help to increase the uniform distribution of the fluid along the length of the receiving chamber 1 and, therefore, along the working bodies of the spacer.
