Description

DESCRIPTION OF A USEFUL MODEL. ||

1. Name of utility model.

Universal ultra-small sprayer. According to the classification, the IPC refers to section A 01 M 7/00.

The utility model relates to devices for chemical protection of agricultural plants of open ground from pests, weeds and diseases by the ultra low-volume method.

It is known to use in agriculture sucker-rod ground ultra-low-volume sprayers with rotating spray disc or drum type (V.F. Dunsky Monodisperse aerosols. Science, 1975). The working width (treatment area) of such sprayers is determined by the width of the span of the extension rods and usually lies in the range of 15 to 24 meters. This value, as well as the speed of the sprayer across the field, determines its productivity, which for the best samples is 300-500 ha per shift.

On the other hand, in recent years, aerosol generators have been used in plant protection practice, with the help of which aerosol wave treatments are carried out (see USSR author's certificate No. 950266, class A 01 M 7/00). In this method, the aerosol fog generated by the generator is blown away by the wind onto the cultivated area, providing (depending on the size of the particles formed) the grip widths from 200 to 2000 m with a productivity of 1,500-10,000 ha per shift. At the same time, the use of aerosol generators in herbicide treatments is sharply limited by the size of sanitary protection zones around fields with herbicide-sensitive agricultural crops and forest stands. As a result, uncultivated areas remain on the field, requiring additional treatments with boom sprayers. However, joint treatments of one field with an aerosol generator and boom sprayers are not currently performed due to the likelihood of burns to the treated cultivation due to the absence of visible boundaries of the treated areas on the field.

At the same time, widespread use in many areas of technology and production of receivers of satellite navigation systems (GPS and GLONASS), the development of portable and handheld computers and software make it possible to visualize on an electronic model of the terrain the boundaries of the propagation of aerosol waves on the treated field and the treated areas with sprayers.

In addition, aerosol treatments require favorable wind conditions, both in wind strength (from 1 to 3 m / s), and in its direction relative to the treated areas. As a result, out of 20-25 work shifts favorable for carrying out treatments, 5-10 fall out due to lack of necessary weather conditions. At the same time, calm night conditions are most favorable for treatments with boom sprayers.

The goals of creating a universal ultra-low-volume sprayer are to increase the productivity and quality of herbicide treatments

agricultural plants.

The goals are achieved in that the universal ultra-low-volume sprayer is an autonomous unit placed on a vehicle and includes an aerosol particle generator, folding booms with spraying devices installed on them, a tank for placing a pesticide working solution and a system for distributing and supplying liquid to nozzles aerosol generator and boom spraying devices.

The utility model is equipped with a navigation system on the Sfee receiver of a satellite navigation system (GPS or GLONASS) and a microcomputer with appropriate software that allows you to visualize the spray path when working with booms on the display screen during processing of the aerosol wave propagation boundary.

Due to the fact that the aerosol generator is included in the utility model, it is possible to conduct high-performance areal treatment of plants using the “aerosol wave method with maintaining the necessary sanitary protection: zones in front of susceptible crops and forest belts.

Due to the fact that the composition of the utility model includes remote booms with spraying devices, the subsequent possibility of carrying out herbicidal treatments near susceptible crops and forest belts is provided.

Due to the fact that the utility model includes a unified system for storing, distributing and supplying working fluid to the forcing of an aerosol generator and rod sprayers, it is possible to select a processing method directly on the field, based on existing weather conditions.

Due to the fact that the utility model is equipped with a navigation system that allows visualizing the cultivated areas, crop burns are eliminated due to reprocessing and work quality is improved.

5. The list of figures of drawings.

Pa fig. 1 shows a general view of a universal ultra-low-volume sprayer, and in FIG. 2 placement of the navigation system in the sprayer cabin.

6. Information confirming the possibility of implementing a utility model.

Pa vehicle (see figure 1) mounted aerosol generator, consisting of a power plant 1, a dispersing device 2 for crushing the working fluid, a fuel tank 3, a start-up system and control the operation of the power plant (not shown), and folding remote rods 4 with sprayers 5, a tank 6 for accommodating the pesticide solution, a filter 7, a pump 8 and a hydraulic switchgear 9 for separately supplying liquid to the dispersing device 2 of the aerosol generator or to boom racks spreaders 5. In the sprayer cabin (see figure 2) the microcomputer of the navigation system is located.

The utility model works as follows.

the current values of the wind direction and force are entered, the power plant (1, Fig. 1) of the aerosol generator is started, and the vehicle moves in the direction perpendicular to the wind direction. The aerosol generated in the dispersing device (2) is blown away by the wind onto the field being treated, while on the computer display of the navigation system inside the field contour, in accordance with the stored aerosol cloud propagation model, the treated area is drawn. For the subsequent processing of the aerosol sanitary protection zones and flaws, the arms 4 are laid out, the hydraulic distributor switches to supply liquid to the rod sprayers 5, and the field is processed by standard driving modes with the control of the capture width on the display screen of the navigation system.
