Abstract

Invention m. used in the mining industry and is intended for the selective extraction of gangue deposits. The goal is to simplify the design and increase the efficiency of the device by reducing the loss of impact energy. In the central channel of the device case, there is a spacer wedge, a drummer, a striker acceleration system with a piston and a cylinder with a piston, and a holding unit in the initial position and the descending drummer are arranged consistently and coaxially along its length. The latter is made in the form of a mechanical fixer installed on the body. To the bevels of the spacer wedge with internal surfaces, face sliding cheeks with transverse pinning elements on the external surfaces abut. A compression spring is installed between the impactor and the piston with an emphasis on their ends. The compression of the spring is controlled by the supply of fluid pressure to the charging cylinder chamber of the ram. The striker's locking device operates, and without loss, it transmits an impulse of force to the wedge, which splits the cheeks. The breed is destroyed. 1 silt (Ls

Description

The invention relates to mining, in particular to devices for the destruction of rocks, and can be used in the mining industry.

The purpose of the invention is to simplify the design and increase the efficiency of the device by reducing the loss of impact energy.

The drawing shows a device for the destruction of monolithic objects.

The device includes a housing 1 in which the drummer 3 is placed in the centrifugal channel 2, the compression spring 4, the piston 5, the return spring 6, the charging cylinder charging chamber 7, the channel 8, the expansion valve

a wedge 9, face sliding cheeks 10, a mechanical clamp 11.

The spacer wedge 9, the drummer 3, the power cylinder with the piston 5 are sequentially and coaxially located the length of the body, the spring 4 is located between the piston 5 and the drummer 3 with an emphasis on their ends. The latch 11 is a holding unit in the initial position and the descent of the striker. This mechanism with the power cylinder, piston and spring 4 forms the acceleration system of the striker. The cheeks 10 have transverse pinning elements on the outer surfaces and abut the inner surfaces on the slopes of the wedge 9.

The device works as follows.

A liquid is pumped into the charging chamber 7 through the channel 8, which, when the piston 5 is moved, performs the work of deforming the springs: the springs 4 for compression and the springs 6 for stretching. Moreover, the compression of the spring 4 is regulated by the supply of fluid pressure to the platoon chamber 7. After the necessary charging of the spring 4, the channel 8 is closed. The mechanical latch 11 in the form of an ejected trigger actuates and releases the drummer 3. The drummer 3 under the action of the spring 4 accelerates in the channel

2 without friction, since the canal and the drummer have no seals. After acceleration drummer

3 transfers the impulse to the force wedge 9. The wedge 9 under the action of the striker 3 moves and pushes the cheeks 10, which destroy the rocks. The piston 5 and the striker 3 return to their initial position due to the spring 6 after the fluid 7 has been drained from chamber 7..

Claims (1)

Formula invented A device for destruction of monolithic objects, comprising a housing with a wedge, a striker, a striker acceleration system with a power cylinder with a barrel and a holding unit in the initial position and a striker descent, sequentially and coaxially located along its length, end cheeks with transverse pinning elements on the outer surfaces, adjacent inner surfaces to the bevels of the expansion wedge, characterized in that simplifying the design and improving the efficiency of the device by reducing the loss of impact energy, it is equipped with a compression spring installed between the hammer and the piston with an emphasis on their ends, in this case, the holding unit in the initial position and the descent of the impactor is made in the form of a mechanical lock mounted on the housing.
