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 difficulty of controlling the process of surface treatment of the part and the unsafe use of it due to the large amount of suspended particles and abrasive.

A device is known, consisting of a body, a removable nozzle, a tip, a container for abrasive placed in the body 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, a feed channel air 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 (RF Patent for utility model No. 191260, application No. 2018133058, publ. 31.07.2019).

The disadvantage of the known device is the difficulty of controlling the process of surface treatment of the part and the unsafe use of it due to the large amount of suspended particles and abrasive.

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

1) a protective cover is installed on the body of the device for cleaning agricultural machinery, covering the removable nozzle and the treated part of the surface of the part, which improves safety when working with the device by limiting the spread of suspended particles formed during the operation of the device and abrasive;

2) the protective cover contains a viewing window with a fixed glass, which allows you to safely control the process of cleaning the surface of the part during operation of the device;

3) the protective cover in the lower part contains a channel for collecting abrasive waste material, which allows you to remove the waste abrasive from the device operation area, reducing its concentration and increasing the convenience of monitoring the cleaning process of the treated surface.

The purpose of the utility model is to improve the safety and usability of the device for cleaning agricultural machinery.

The technical result consists in the convenience of monitoring the cleaning process and the safety of the device by eliminating the spread of a large amount of suspended particles and abrasive material in the treated surface area.

The specified technical result is achieved through the use of a device for cleaning agricultural machinery, containing a body, a removable 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 a trigger, wherein a protective cover is installed on the body, covering the removable nozzle and the treated part of the workpiece surface, containing a viewing window with a fixed glass, and the protective cover in the lower part contains a channel for collecting abrasive waste material.

The utility model is illustrated by the graphic material presented in the figure - a longitudinal section of a device for cleaning agricultural machinery.

The claimed device (figure) 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 supplying 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, and a protective cover 13 is installed on the body 1, covering the removable nozzle 2 and the treated part of the surface parts 14, containing a viewing window with fixed glass 15, and the protective casing 13 in the lower part contains a channel 16 for collecting abrasive waste material.

The device works as follows.

Before the start of 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.

In the process of starting to clean the surface of the part 14, the protective cover is leaned against the surface to be treated as tightly as possible. Visual control of the process and quality of cleaning is carried out through a viewing window with a fixed glass 15 installed in a protective casing 13.

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. pressure that contributes to the ingress of the abrasive into the mixture supply channel 7. Suspended particles formed during the operation of the device and the abrasive are in the volume limited by the protective casing 13 and the workpiece surface 14. The spent abrasive falls into the channel 16 to collect the abrasive waste material and is disposed of or cleared for reuse.

The application of the proposed utility model will improve the safety and ease of use of the device for cleaning agricultural machinery.
