SU107040A1 - Executive body of rotary impact machines - Google Patents

Description

The subject of the invention is a pulsatile body of percussion-rotary machines designed to locate workings of different sections in sedimentary mountain norons of medium and the gain of medium strength, made in the form of freely suspended pas using a camshaft with independent drive of multi-tooth workers. .

In known machines designed for the passage of mine workings, the executive bodies work as cutters or cone cutters, which, without turning through the shafts, destroy the rock.

A distinctive feature of the proposed executive body of the hinges is the landing of multi-tooth working elements to give them the functions of the strikers on the axes with a large gap, as a result of the rotary shaft, due to the eccentricity created by the centrifugal forces, the impactors acquire the necessary kinetic energy spent on time | Breeding of the rock in contact with the bottom.

With such an execution of the percussion organ of machines of percussion action, the working multi-tooth elements do not mill the rock, but cut it, as a result of which more () efficient passage of the workings can be achieved.

An ulpnte; the 1st organ of the machines receives the trajectory of the movement of the strikers on the surface of the slab in the form of an elongated cycloid (trochoid).

Ma FIG. 1 shows the executive body in two projections; in fig. 2 - diagram of the machine with the executive bodies of the impact-vap1, its action in the face.

The executive body consists of one or more paired

drives / inside which, with nOMOHlblO

BTyvioK 2 spacer and fingers 3, a few impactors 4 and 5 are freely suspended, made in the form of a multi-tine cymbal milling cutter, reinforced with a hard alloy 6. The multi-tooth milling cutters are suspended so that a gap 7 and

cutters start working as drummers. When the disks are rotated, the cutters, under the action of their own centrifugal forces, select a gap and acquire the necessary kinetic energy, which it gives back to the face.

Due to the free suspension of the udracks, the working body has no recoil and allows one to obtain any frequency of strikes.

According to the scheme., On the shaft of the 8 shafts 8, each of the individual drives from the electric motor I have fixed the disks 10, with which the impactors are driven freely. //.

The radial shafts 8, in addition to the woundaround around its own axis, receive wrenching in the bottomhole around the axis after T, which with the help of the driving drive shaft 12.

The subject is invented and
