Description

Изобретение относитс к сельскому .хоз йству , а именно к области химической защиты растений, и может быть использовано в распыливающих рабочих органах опрыскивателей .The invention relates to agriculture, in particular to the field of chemical plant protection, and can be used in sprayers working spray bodies.

Известен распылитель, включающий сообщенный с гидравлической магистралью наконечник с каналом дл прохода жидкости и распыливающим отверстием и эжекционную насадку, соединенную с наконечником 1.A sprayer is known, which includes a tip connected to the hydraulic line with a passage for the passage of fluid and a spray hole and an ejection nozzle connected to tip 1.

Недостатками известного распылител вл ютс отсутствие возможности регулировани распьгла по диаметру капли и мала щирина захвата, а также больщие по длине габариты насадки.The disadvantages of the known sprayer are the inability to adjust the spray diameter of the droplet and the small width of the grip, as well as the dimensions of the packing that are larger in length.

Цель изобретени - регулирование распыла по диаметру капель и увеличение щирины захвата.The purpose of the invention is to control spraying on the diameter of the droplets and increase the width of the grip.

Достигаетс эта цель тем, что в предлагаемом распылителе эжекционна насадка соединена с наконечником шарнирно с возможностью поворота в вертикальной плоскости и снабжена жестко св занным с ней дефлектором.This goal is achieved by the fact that, in the proposed sprayer, an ejection nozzle is connected to the tip pivotally with the possibility of rotation in a vertical plane and provided with a deflector rigidly connected to it.

С целью снижени габаритов насадки в наконечнике соосно с ним установлен вкладыш , имеющий конический-канал с цилиндрическим выходным отверстием.In order to reduce the dimensions of the nozzle, a liner having a conical channel with a cylindrical outlet opening is installed in the tip coaxially with it.

На чертеже показан продольный разрез предлагаемого распылител .The drawing shows a longitudinal section of the proposed spray.

Распылитель имеет гидравлический наконечник 1, вкладыш 2 с коническим каналом , эжекционную насадку 3 с отверстием круглого сечени и плоским пазом на торцовой поверхности со стороны выхода факела . На конце насадки жестко установлен дефлектор 4.The atomizer has a hydraulic tip 1, an insert 2 with a conical bore, an ejection nozzle 3 with a round hole and a flat groove on the end surface on the outlet side of the torch. At the end of the nozzle the deflector 4 is rigidly mounted.

Наконечник и насадка св заны поворотной осью 5 и скреплены регулировочным винтом 6 с фиксирующей гайкой 7.The tip and nozzle are connected by a rotatable axis 5 and fastened with an adjusting screw 6 with a fixing nut 7.

Распылитель работает следующим образом .The spray works as follows.

Claims

When leaving the hydraulic nozzle, the liquid formed into the jet enters the ejection nozzle, ejects air in the gap between the nozzle and the nozzle and then, striking the deflector, is thrown into the side slot of the nozzle in the form of a flat torch. Upon impact with the deflector, the jet forms a liquid film on it, which drains and crushes at the edge of the deflector. The average size of droplets of the sprayed liquid depends on the thickness of this film and its energy. These parameters can be changed. The point of contact of the jet with respect to the edge of the deflector can be changed: the disintegration of a thin film, having considerable kinetic energy to it, makes it possible to produce small droplets. The ejected air partially serves as an additional atomizing medium, partially aerates the liquid, forming a foam in the presence of minor amounts of a frother. The implementation of the spray gun according to the invention makes it possible to regulate the spray pattern over the diameter of the droplet over wide limits with constant fluid parameters in front of the hydraulic tip, suggests the possibility of using a sprayer to carry out field treatments at the time of the action of various weather factors (strong wind, high temperature, etc.) and setting hopper on the desired mode of operation. Adjusting the working width allows the same sprayer to be used for both wide-spread and tape treatments. Claim 1. Sprayer includes a tip with a fluid passageway and a spray hole and an ejection nozzle connected to the nozzle, characterized in that in order to regulate the spraying of the fluid according to the droplet diameter and increase the working width, the ejection nozzle is connected to the tip is pivotally rotatable in the vertical plane and is provided with deflector res. rigidly connected with it.

2. Sprayer according to Claim 1, characterized in that, in order to reduce the dimensions of the nozzle, a liner having a conical channel with a cylindrical outlet opening is installed coaxially with the nozzle.
