Description

II 1

The invention relates to agricultural machinery and is intended for the chemical treatment of plants, in particular for the defoliation of cotton.

The purpose of the invention is to improve the uniformity of spraying.

Figure 1 shows a field spraying machine, a general view; Fig. 2 illustrates the principle of operation of the nozzles for spraying the liquid and air; Fig. 3 is a diagram of the formation of a spray of liquid along a rod; Fig. 4 shows a spray dispenser; figure 5 is a section aa in figure 4; nbig.b- nozzle having a mirror position of the input channel,

The field spraying machine contains mounted on the frame 1 of the vehicle 2 and connected to the pump 3 carrying pneumatic arms 4, made in the form of cones. On pneumatic consoles 4 centrifugal nozzles 5 are installed for spraying fluid. Which are placed on the console 4 in two rows with displacement one relative to another in a checkerboard pattern (FIG. 3) and with the rotation of the jets opposite in the direction. To this end, the input channels 6 of one row of dbopcyHoK 5 are set to mirror the input channels of 7 nozzles of the other row. Above centrifugal nozzles 5 for prices for spraying liquids prices are set at 222352

robust air nozzles 8 connected to pneumatic brackets 4, i.e. the air in the nozzles 8 comes directly from the consoles 4, 2 which are under excess

pressure. The direction of rotation of the airflow leaving the air nozzles 8 coincides with the direction of rotation of the centrifugal nozzles 5 (liquid). The nozzles 5 are connected via pipe 9 to the pump 3. The nozzles 5 have a cylindrical channel 10 and an outlet 11. The design of the air nozzles 8 is similar to the design of the nozzles 5.

The field spraying machine works as follows.

The jets of sprayed liquid and air of one row emitted by centrifugal nozzles 5 and 8 interact with similar jets (directed in the opposite direction) of another row (Fig. 3). As a result of this interaction, a path is formed, containing both chemical chemicals dissolved in the liquid and air jets. As a result, plants are treated not only from above, but also from the side, which greatly increases the spraying efficiency.

In addition, the placement of air nozzles 8 above the nozzles 5 helps to reduce the splashing of particles of chemicals in different directions.
