Description

The utility model relates to devices designed for jet pneumoabrasive treatment of machines and mechanisms, and can be used when cleaning agricultural machinery from corrosion and contamination.

Known design of the gun for abrasive-air surface treatment, consisting of a body with nozzles for supplying materials and a chamber in which a nozzle is installed for supplying abrasive; the inner surface of the outlet nozzle has a conical-cylindrical shape, and the abrasive supply nozzle is made in the form of a nozzle installed coaxially at the beginning of the conical part and the outlet nozzle with an annular gap relative to the critical section of the chamber, while the plane of its outlet hole coincides with the critical section (RF Patent for invention No. 2137593, application No. 98109378, published on September 20, 1999).

The disadvantage of the known device is the complexity of processing hard-to-reach areas.

A known device consists of a housing, a removable nozzle, a tip, a container for abrasive placed in the housing and containing mesh holes, a channel for supplying an abrasive-air mixture, equipped with mesh and bypass holes of different diameters, providing dual-mode operation of the device, an adjusting screw, an air supply channel into the container for the abrasive, which communicates with the channel for supplying high pressure air, a handle equipped with a channel for supplying high pressure air and a trigger (Patent of the Russian Federation for utility model No. 191260, application No. 2018133058, publ. 07/31/2019).

The disadvantage of the known device is the complexity of processing hard-to-reach areas.

The device meets the criterion of novelty as it has the following distinctive characteristics:

1. The tip of the device for cleaning agricultural machinery is made in the form of a hinge, which allows you to change the angle of inclination of the nozzle and, accordingly, the direction of the supply of the abrasive-air mixture, if necessary, processing hard-to-reach areas;

2. The channel for supplying the abrasive-air mixture in the tip of the device for cleaning agricultural machinery is made in the form of branching channels located at an angle to each other, which allows, by changing the angle of inclination of the nozzle, to ensure the supply of the abrasive-air mixture without additional resistance through the open part of the branched network channel;

3. The nozzle of the device for cleaning agricultural machinery is made with a position lock, which allows you to fix the position of the nozzle at the required angle for processing hard-to-reach areas.

The purpose of the utility model is to improve efficiency and usability.

The technical result consists in changing the direction of the abrasive-air mixture when processing hard-to-reach areas.

The specified technical result is achieved through the use of a device for cleaning agricultural machinery, containing a body, a nozzle, a tip, a channel for supplying high-pressure air with a fitting, a channel for supplying an abrasive-air mixture with mesh holes, a container for abrasive with mesh holes, an adjusting screw and trigger, and the tip is made in the form of a hinge, and the channel for supplying the abrasive-air mixture is made in the tip in the form of branching channels located at an angle to each other, and the nozzle is made with a position lock.

The utility model is illustrated by the graphic material presented in the figures:

fig. 1 - longitudinal section of a device for cleaning agricultural machinery;

fig. 2 - extreme upper position of the nozzle inclination relative to the tip;

The claimed device (Fig. 1) includes: a housing 1, a removable nozzle 2, a tip 3, and the outlet part of the housing 1 and the inner surface of the removable nozzle 2, coaxially mounted on the housing 1 by means of a threaded connection, form a mixing chamber 4, a channel 5 for supply high-pressure air with a fitting 6, a channel for supplying an abrasive-air mixture 7 with mesh holes 8, a container for abrasive 9 with mesh holes 10, an adjusting screw 11 and a trigger 12, with the tip 3 made in the form of a hinge, and the channel for supplying abrasive air mixture 7 is made in the tip 3 in the form of branching channels located at an angle to each other, and the nozzle 2 is made with a position lock 13.

The device works as follows. Before starting operation, the removable nozzle 2 is removed, and abrasive is poured into the container 9 through the outlet part of the housing 1. Then, by means of a threaded connection, the removable nozzle 2 is attached to the body 1 (in this case, the volume of the mixing chamber is regulated by the longitudinal displacement of the nozzle when it is screwed onto the body). The adjusting screw 11 is turned until the mesh holes 10 on the abrasive container 9 coincide with the mesh holes 8 in the channel for supplying the abrasive-air mixture 7. From an external source, through the fitting 6, air under pressure enters the channel 5.

When the trigger 12 is pressed, compressed air through channel 5 enters the channel for supplying the abrasive-air mixture 7. Through the mesh holes 8 and 10, the abrasive from the container 9 enters the air flow, which is directed through the channel for supplying the abrasive-air mixture 7 to the mixing chamber 4 From the mixing chamber 4, the mixture of air and abrasive through the removable nozzle 2 exits under pressure to the workpiece surface 14. Part of the air flow from the channel 5 for supplying high-pressure air passes into the container 9 where it mixes the abrasive, preventing it from caking, and also creates pressure , which contributes to the penetration of the abrasive into the mixture supply channel 7.

When processing hard-to-reach places, the position lock 13 is loosened (Fig. 2) and the nozzle 2 rotates relative to the tip 3 at an angle corresponding to the coincidence of the outlet of the open branch of the channel for supplying the abrasive-air mixture 7 and the outlet of the nozzle 2. In this case, the nozzle body 2 overlaps the rest branches of the channel for supplying the abrasive-air mixture 7 in the tip 3. After that, the angle of inclination of the nozzle 2 is fixed by the position lock 13 relative to the tip 3. Next, the operation of the device begins.

The application of the proposed utility model will improve the efficiency and usability of the device for cleaning agricultural machinery.
