Definitions

• the invention relates to the field of disposal of small arms cartridges (PSO), and in particular, to the technology of dismantling cartridges for component parts including a sleeve, bullet, gunpowder in an automated mode with the possible reuse of individual parts of the cartridge and the processing of other parts into industrial materials destination.
• PSO small arms cartridges
• dismantling cartridges refers to fire and explosive.
• even partial scattering of gunpowder on the actuators of the equipment and cartridge elements creates an explosive condition TM.
• the removal of gunpowder from the sleeve must be carried out in containers installed in the explosion-proof cabin.
• the sleeve moves with powder in one channel, invariably covered with powder dust.
• the powder When a bullet is removed from the sleeve, the powder also splashes out, falling on the actuators.
• the objective of the present invention is to provide a highly productive, reliable in operation and providing conditions of fire and explosion safety technologies and equipment for dismantling the SAR.
• the technical result obtained from the invention is to create a method and device for dismantling a cartridge, excluding dispersion - dusting of powder and powder dust on the actuating mechanisms of the equipment and cartridge elements (sleeve, bullet) and providing an explosion-proof system for collecting powder into transported containers and removing these containers without stopping the equipment.
• the specified technical result is achieved by the fact that the extraction of the bullet from the sleeve is carried out with the vertical location of the cartridge bullet up in two stages.
• the bullet is preliminarily removed from the sleeve by an amount that allows air to pass into the sleeve, but which holds the dispersion of gunpowder from the sleeve.
• the final extraction of the bullet from the sleeve is carried out. In this case, the extracted bullet is forcibly released from the grabs and freely pushed into the receiving tank.
• the sleeve is freed from gunpowder in an explosion-proof armored cabin made with two chambers isolated from each other, in which containers for receiving gunpowder are installed.
• the latter is weighed, and the gunpowder is sent to the free tank of another insulated chamber of the armored car, which is blocked for opening. This allows you to remove the container filled with powder without stopping the machine and thereby ensure continuous operation of the equipment in compliance with safety requirements. Filled containers can also be monitored by the dose calculated.

• Instrument block 5 (Fig. 4) comprises a top housing 21 in which a movable slider 22 is mounted, freely connected to the slider nom 16 rotor. On the slider 22, freely swinging jaws 23 are fixed, a spring-loaded sleeve 24 pressing the jaws 23 and a spring-loaded ejection punch 25. A cam 26 and an abutment 27 are rigidly fixed to the housing 21. In the lower case 28 of the block, the cartridge fastens for a groove .

• the machine works as follows.
• the cartridges oriented in the loading devices 2 (FIG. 1) are transferred to the position of the feed transport rotor 3, which, as it rotates, transfers the cartridges with the bullet up into the tool blocks 5, in which the cartridge is dismantled.
• the slider 16 of the technological rotor moves, as the rotor rotates, in the drum 15 along the copy 17, and controls the movement of the slider 22 of the tool block.
• the cartridge transport rotor is installed in the lower housing 28 of the tool block (item 1).
• the slider 22 lowers down and clamps the grippers 23 bullet (pos. 2).
• the slider rises up, previously removing the bullet on a certain a second value, and stops for the purpose of air passage (item 3), excluding the splashing of gunpowder from the sleeve.
• the grips 23 slide over the cam 26 with their outer shoulder, turn around their axis and release the bullet.
• the punch 25 hits the support 27, stops, acts on the bullet remaining in the grips, and pushes it into the tray 19 (Fig. 2).
• the slider lowers down to its original position, and the sleeve is captured by the transport rotor (pos. 5) and in the armored cab zone it is rotated by an angle of 160 to 200 ° and the powder is poured into the tray 8 (Figs. 1, 2, 3), according to which the powder is poured into the rotary tray 9 and then into one of the containers 10.
• the sleeve upon further rotation of the transport rotor, is discharged into the tray 20 (Fig. 2).
• the tray As the capacity is filled by the signal of the weight control sensor of the powder 11, the tray, under the action of, for example, the drive of the electromagnet 14, rotates around its axis and is mounted above the free capacity. At the same time, the latch 12, mounted on an axis, releases the lock 13 on the doors of the chamber and locks the door of the other chamber. The filled tank is removed from the armored car without stopping the machine.
• the invention used in the machine provides fire and explosion safety, high productivity of the process of dismantling the PSO, reliability in operation during operation, simplicity of design.
