(54) DEVICE FOR DESTRUCTION OF MOUNTAINS

The invention relates to gene, mining and chemical and chemical technologies, namely devices for the destruction of gene rocks, and can be used in dynamic structures, tapoxoic combines and installations for the crushing of oversize. A device is known for the operation of mountain psfods, including, a firing pin, a platoon slab, a drain and melody chamber, and a pneumatic accumulator. Fucking the piston with the drain and valoric chambers, the maola is drained and the water is subsequently divided by the action of a pneumatic accumulator to combine the 1J stroke. The closest to 1Pep agam is a rock dumping device, including a housing, a firing pin with a piston and a rod, an overflow channel is made, a drain into the pressure chamber, a battery and a working tool 2. A disadvantage of the known devices is that the firing pin has a slight displacement amplitude, as a result of which it has a low single impact. The purpose of the invention is to increase the efficiency of destruction by increasing the single impact. The goal is achieved by the fact that the rod has a sleeve coaxially mounted on it and located in the drain chamber with the possibility of periodically blocking the flow channel and is accumulated in the form of a pneumatic chamber, this housing has damping stops located on the front sides of the sleeve. FIG. 1 shows a device for rock mining, a general view; and FIG. 2 - position of the striker at the platoon stage; in fig. 3 - the same, at the stage of the strike. The device consists of a housing 1, inside of which are mounted a drainage chamber 2 with a channel 3, a pressure chamber 4 with a channel 5 to the battery in the form of a pneumocamera 6, and also a firing pin 7 with a piston 8, a rod 9 and an overflow channel 10. In the drain chamber 2 A sleeve 11 is located coaxially with the rod 9 between the oeyMia damping supports 12 and 13. A working tool 14 with a shank 15 is installed in the box 16. In case I, there is a compensation channel 17. The device works as follows. The channel 5 feeds oil into the pressure chamber 4, which, acting on 8, moves the head 7 to the right, compressing the gas in the pneumatic chamber 6 until the sleeve 11, resting on the shock absorber 13, opens the drain part of the overflow channel 1O. When the drain part of the channel 10 is opened, the pressurized oil from the pressure chamber 4 through the overflow channel 10 penetrates the gap between the shock absorber 13 and the sleeve 11, enlarges this gap and flows into the drain chamber 2 and then enters the channel 3. In this case, the striker 7 moves to the left under the action of expanding gas pneumatic chambers 6. As soon as the firing head 7 begins to move to the left, the drain part of the overflow channel 10 opens to the full cross section and the oil flows out at a speed that does not prevent the movement of the striker 7. Reaching the maximum speed ek 7 blows on the shank of the working tool. During the impact, the hammer 7 slows down its movement, and the sleeve 11, moving by inhibition, compresses the air gun 12 and under its effect returns to its original position.

And 14 marriages, i.e. closes the drain part. channel 10. Further, the cycle is repeated. Thus, the movable sleeve 11 and the depreciation stops 12 and 13 will increase the movement of the striker, and thereby increase the energy of a single shock at the same initial pressure or less in the battery. The use of the invention in dynamic structures, executive bodies of combine harvesters and installations for crushed non-dimensions will increase the productivity of these machines. The scope of the invention. A device for rag rock formations, comprising a housing, a firing pin with a piston and a rod, in which an overflow channel is made, a drainage chamber and a pressure chamber, a battery and a working tool, characterized in that, in order to increase the efficiency of destruction by increasing energy unit impact, the stem has a sleeve installed coaxially on it and located in the drain chamber with the possibility of periodically blocking the overflow channel, and the battery is made in the form of a pneumatic chamber, while the body has shock absorption stops located on the front side of the sleeve.
