The present invention relates to agricultural machinery, mainly to sprayers for processing of field crops and perennial plantings small doses of the working fluid.

Known ultra-low volume sprayer according to patent RU 2058740 C1, A01M 7/00, 1996, consisting of frame, tank, piping, duct, spray in the form of streammessage device with a slit nozzle and feeding tube connected to the tank.

The disadvantage is the large local resistance at the entrance of the air in the slit nozzle, causing pressure loss in the nozzle, and the small width of the jet at the exit and limited fluid flow from the feed tube atomizer.

Also known ultra-low volume sprayer (patent RU 2275022 C1, A01M 7/00, 2006, prototype) containing frame, tank, balance tank, piping, duct and a nozzle comprising an air tube, the upper plate and the base are separated by a spacer, forming a slit nozzle, to which is installed a feeding tube.

The technical solution is to save the consumption of the working fluid increases the width of the grip, performance and extend the range of doses of fluid flow and obtaining the required quality of processing.

The technical problem is solved in that the sprayer ultra is Alabyana, containing frame, tank, balance tank, piping, duct and a nozzle comprising an air tube, the upper plate and the base are separated by a spacer, forming a slit nozzle, to which is installed a feeding tube, an air tube mounted coaxially delavau the nozzle and the seal is made of two parts which are output form the radial curve, with a feeding tube installed horizontally, has an arched shape and at the bottom of the hole.

The ultra-low volume sprayer has a set of nutrient tubes with different number of holes and diameter depending on the flow rate of the working fluid.

The novelty of the claimed proposal due to the fact that, compared with the prototype has a more economical design, so as to decrease the pressure loss at the air inlet of the air supply through an air tube in a slit nozzle, increases the width of the dispenser extends the range of fluid flow, improving the quality of dispersion and uniformity of its distribution width.

According to scientific, technical and patent information not revealed the claimed combination of features, clearly stemming from the current level of technology that allows to make a conclusion about the electoral level proposed izaberete the Oia.

The invention is illustrated by drawings, where figure 1 is a flow diagram of the sprayer, figure 2 - a view a-a jet element.

The sprayer includes a frame (not shown)on which is mounted the tank 1 with the working fluid, hydrobromide 2, a balance tank 3 with the valve 4, the duct 5 and the spray air tube 6, screwed into the base 7 and the upper plate 8 streammessage device coaxially delavau the nozzle formed by the two parts of the strip 9 with the output form of the radial curve. In front of the nozzle set replacement feeding tube 10 arcuate form with the required number and diameter of holes, depending on the flow rate of the working fluid.

Streamresult device and a feeding tube is mounted in the cylindrical housing 11.

Works sprayer as follows.

Air from a compressor or other source (not shown) is supplied under pressure through the duct 5 in the tube 6 of the spray, where to expire through a slit nozzle, formed by the base 7, the upper plate 8 and the parts of the strip 9 with the outlet radial form, where the form of plane-parallel jet injects and disperses the liquid stream flowing from the tank 1 via line 2 through the balance tank 3, tap 4 coming in nutrient T. the pipe 10 in the arcuate form with the required number and diameter of holes depending on the flow rate of the working fluid.

For example, processing of perennial plants, when you need a large flow rate of the working fluid, installed a feeding tube, where the diameter and number of holes maximum (3...5 mm and the number 4, 5, 6), for processing the series of field crops (corn, sunflower), requiring less fluid flow, number of holes 1 to 3 with a diameter of 1...3 mm

The sprayer can be used to manipulate various objects, including soil, field and perennial crops.

The ultra-low volume sprayer containing frame, tank, balance tank, piping, duct and a nozzle comprising an air tube, the upper plate and the base are separated by a spacer, forming a slit nozzle, to which is installed a feeding tube, wherein the air pipe is mounted coaxially delavau the nozzle and the seal is made of two parts which are output form the radial curve, with a feeding tube installed horizontally, has an arched shape and at the bottom of the hole.
