Description

The invention relates to mechanical engineering, in particular, to the design of percussion machines, and can be used in construction, mining, as well as in riveting hammers during assembly operations.

The purpose of the invention is to increase the impact power.

Fig. I depicts a percussion machine; longitudinal section; in fig. 2 is a section A-A in FIG. 1 (on a curved surface).

The percussion machine comprises a housing 1 with a single-arm lever 2, one end of which is fixed on the axis of rotation 3, and the other is connected to a jet nozzle 4 and a spherical element 5, and a working tool 6. In housing 1 there is a cavity 7 with a curved surface with opposing its ends are 8-reverse chambers interacting with the surface of the jet nozzle 4, the latter is hinged to the lever 2, and the machine is equipped with 6 strikers 9 spring-loaded to the working tool, alternately interacting with one end them the tools 6, and the other - with spherical element 5,

Percussion machine work as follows.

If the working tool 6 is not in contact with the object to be broken, then the strikers 9 are recessed towards the working tool 6 and do not touch the spherical element 5, and the jet nozzle 4 is at the bottom of the reverse chamber, which cannot be turned 180 ° (Fig. 1) The liquid flowing from the reactive sol 4 is discharged through the nozzle 10 of

cavity 7 into the atmosphere. The percussion machine is in idle mode.

In contact with the working tool 6 with the destructible object, the firing pin 9 moves to the stop in the direction of the spherical element 5 and lifts the lever 2 from the bottom of the chamber 8 of the reverse. Jet nozzle 4, articulated

connected to the lever 2, turns 180, contacts its surface with the surface of the cavity 7 (Fig. 2) and under the action of the reactive force moves in the cavity 7

from one extreme to the other. When moving jet nozzle

4 with lever 2 and spherical element

5 accelerating, and the latter, striking the head 9, transfer the stored

energy to the working tool 6, which destroys the object. The jet nozzle 4, being at this time in the chamber of the reverse, is rotated by 180 ° under the action of reactive force and,

coming into contact with the curved surface of the cavity 7, rushes into the opposite wing of the cavity 7, where the element 5 of the lever 2 also contacts

with the striker 9, which, in turn, transmits the impact energy through the working tool 6 to a destructible object. The process repeats, the percussion machine does work to destroy the object.

In order to take the machine out of the operating mode, its working tool 6 should be torn off from contact with the object being destroyed.

Thus, the invention contributes to an increase in the shock power of the machine.
