Combined injection wheel
SUBSTANCE: combined injection wheel consisting of airbrush fixed on a tube, into which the working fluid may be fed through a pipe. The airbrushes have lids with output ports for fluid spraying and a dabber airbrush with a spherical inlet and a screw-type channel at the outlet. The combined injection wheel contains stream separator, which is connected with a distributor of the stream separators. The distributors are constricted by a wire nail and a presser and form a general pressure distribution chamber, which is isolated by weatherstrips. The stream separator is screwed to a tubular nipple fixed on a rack-and-pinion gear. The airbrushes are fixed on the sides opposite to the separator and may be rotated about the transversal axes of the holes of fluid passing from the upper part of the separator to the lower part of the airbrushes for increasing the spray cone. The dabber airbrush is installed inside of the outlet port of the lid.

The invention relates to a device for processing fruit trees, berry bushes, vegetables for chemical protection against pests and diseases, as well as foliar feeding, economical watering with a wide dispersion in the conditions of farms and garden plots.
Known used in private gardens and even farmers portable sprayers, consisting of a reservoir for the working fluid from the filler neck filter, hand pump and outlet tube hose (see SU # 246207, IPC AM 7/00).
Known portable sprayers, which are filled with fluid and pumped up in her air-operated actuator (smatest Ukraine UA No. 23404, CL AM 7/00, the Federal Republic of Germany patent DE No. 19511885, CL AM 7/00). The spray liquid flows in these sprayers are driven by compressed air from the foot or hand pumps.
The disadvantage of these hand and foot sprayers: low pressure spray, weakening as emptying the tank, hard work during the swing of the air, a short tubular arm, a single spray head. As a result, they are not suitable for spraying tall fruit trees and have low productivity. Combined spray heads for hand-held sprayers impractical because of the loss of pressure during emptying of the tank. Pressure fluid barely hatena one spray head at the beginning of evacuation.
Known machines for chemical protection of plants - machinery sprayers pumps. Working bodies of these sprayers consist of tanks, pumps, filters, pressure regulators, nozzles, spraying systems, and fuel devices (See. Tutorial Wemhoener, Ipharmacy "Agricultural machinery", str...223. Moscow, "Colossus", 2004 (1)).
In the engine sprayers establish a powerful piston, centrifugal, gear, diaphragm, roller and rotary pumps. The main characteristics of the pump flow (l/min) and fluid pressure (MPa).
From pumps, machinery sprayers working fluid enters the distribution system, which serve to move the sprayed fluid flow and applying it to the object of treatment through spray heads installed on hose spray systems.
Key performance indicators of the spray tips - quality spray angle spray α (see (1), .VI.3, str) and the flow rate per unit time. The quality of the spray is determined by the diameter of the droplets, which are determined depending on droplet size (degree of dispersion). There are globular (more than 300 μm), atomized (150...300 µm), fine (50...150 μm) and aerosol (less than 50 microns) raspily.
Diameter to the drops decreases with increasing pressure and decreasing the hole diameter of the nozzle. For fine spray apply the spray with a small hole, and the operating pressure is increased. Globular get spray for large holes and small pressure in the pressure line.
Circular saw trimming tips (nozzles) form a stream of liquid into a solid or hollow cone, fan, solid film. Sprayers - the most important part of the sprayer, from the correct selection of which depends on the uniformity of application of chemical plants. They are placed on the pipe collector distribution systems machinery sprayers, in which the pump pumps the working fluid. In reservoirs with holes through which the liquid flows into the cavity of the spray head (see (1), .VI.3, a, b, C, str)attached to the pipe manifold. The head cap is attached liners nozzles with openings for the fluid spray. The spray head is provided with a shut-off valve. At normal pressure in the pressure line fluid lifts the valve, passes through the filter, liner dispenser and dispergirovannom as applied to the processing object.
At the time of turning off the flow of fluid in the pressure line (on the edge of the field or stops) the pressure in the reservoir decreases, the valve under the action of the spring closes the passage of liquid to the atomizer and predotvraschaya the spontaneous leakage of fluid and environmental pollution.
Single spray head (see (1), VI.3, and str) has one atomizer, and combined (see (1), .VI.3, b, str)) - two, three, or four. Turn the clip on the housing, one atomizer is installed in the lower (working) position to align its channel with the outlet of the housing. The use of such heads reduces the time for reconfiguration of the sprayer in the new mode of operation.
Design of liners and the principle distinguish the spray field, centrifugal, fricatives, deflector, ejection, a centrifugal disk and disk with electrotheraphy drops.
Closest to the claimed spray head of the field sprayer machine sprayers.
Field sprayer (see (1), .VI.3,, str) made of plastic cap from the outlet and core with a spiral groove. The diameter of the hole cap of 1.5 and 2 mm Helical grooves formed by the liquid flow.
Known dispensers machine sprayers, high-performance, but it is inconvenient and uneconomical in private gardens.
Machine sprayers work under great pressure pressure on many dispensers and in them there is no need to save jet and be safe in the work of the pump when the clogging of one or two sprays. In a combined spray head textile the sprayer in the work always one atomizer, while others set up one for the other mode.
The technical result, which directed the present invention is the creation of nozzles on the basis of cheap, lightweight sprayers, economical and fairly high vibration electromagnetic pumps.
