Abstract

The utility model is aimed at increasing efficiency, reducing drug drift and improving the quality of the atomizer. The specified technical result is achieved in that the liquid atomizer includes a housing with a rotating conical bowl located in it with an annular gap relative to its inner conical surface with an opening in its upper part. An additional second rotating cup is located in the housing, having a cylindrical part turning into a cone and made as a unit with a drive roller mounted in the housing on bearing bearings. The cylindrical part of the second rotating bowl, as well as the fluid supply pipe, rigidly fixed in the housing, the internal cavity of which is in communication with the air supply pipe, fixed in the housing, pass through the opening of the rotating conical bowl. The rotating conical bowl and the conical part of the second rotating bowl coaxially with the annular gap are interconnected by means of fixing pins. 1 ill.

Description

The utility model relates to mechanical engineering, namely to devices for spraying liquids and can be used as part of sprayers to protect crops from pests and diseases of crops.

Known sprayer, including a transverse rod with vertical uprights mounted on them with rotary nozzles, each of which has an individual drive, a housing, a rotating conical bowl and a fan impeller, mounted on a common shaft, as well as pipelines for supplying fluid to the sprayer (SU No. 581914, M. CL A01M 7/00, publ. 11/30/1977.).

A disadvantage of the known device is the presence of one annular gap for the exit of the air flow, which reduces the deposition rate of an airborne droplet jet on the treated object, and reduces the quality of the spray torch.

The technical result consists in increasing efficiency, reducing drug drift and improving the quality of the atomizer.

The technical result is achieved by the fact that the liquid atomizer includes a housing with a rotating conical bowl located in it with an annular gap relative to its inner conical surface with an opening in its upper part. An additional second rotating cup is located in the housing, having a cylindrical part turning into a cone and made as a unit with a drive roller mounted in the housing on bearing bearings. The cylindrical part of the second rotating bowl, as well as the fluid supply pipe, rigidly fixed in the housing, the internal cavity of which is in communication with the air supply pipe, fixed in the housing, pass through the opening of the rotating conical bowl. Rotating conical bowl and

the conical part of the second rotating bowl coaxially with the annular gap are interconnected by means of fixing pins.

Figure 1 shows the structural diagram of the device. The liquid atomizer includes a housing 1, on which a pipe 2 for supplying a working fluid and a pipe 3 for supplying air are rigidly fixed. The internal cavity of the housing 1 is in communication with the pipe 3 for supplying air. Inside the housing 1 there is a rotating cup 4, which has a cylindrical part, turning into a conical one, and made integrally with a drive roller 5 mounted in the housing 1 on the bearings 6. On the conical part of the rotating cup 4 is mounted coaxially with an annular gap 7 on the fixing pins 8 rotating conical bowl 9 with a hole 10 in its upper part, through which the cylindrical part of the rotating bowl 4 and one of the ends of the pipe 2 for supplying the working fluid. The rotating conical bowl 9 and the inner conical surface of the housing 1 are separated by an annular gap 11.

The device operates as follows. The electric motor drive is turned on, the fluid is supplied through the pipe 2, and the air is supplied under overpressure through the pipe 3. The fluid through the pipe 3 enters the inner wall of the rotating conical bowl 9 and is sprayed by centrifugal forces. The air flow supplied from an external source leaves the atomizer in two ways: the first path is through an annular gap 7 formed by a rotating bowl 4 and a rotating conical bowl 9, together with the working fluid, thereby increasing the rate of fluid outlet. The second way is through the annular gap 11 formed by the conical surface of the housing 1 and the surface of the rotating conical bowl 9. At the exit, these flows are connected, forming an air-drop mixture directed to the crown of plants. The size of the droplets can be adjusted by the speed of rotation of the drive roller 5 and the flow of air through the pipe 3 for air supply.

Compared with the known solution, the proposed solution allows to increase the spraying efficiency, reduce the drift of the working fluid and improve the quality of the sprayer due to the additional annular gap between two rotating bowls. The specified annular gap allows you to increase the rate of deposition of particles of the working fluid, while reducing the drift of the particles, thereby reducing the flow rate of the working fluid and environmental pollution.
