Description

MACHINE FOR TRAINING PREPARATORY AND CUTTING PRODUCTS

It was filed on April 17, 1958 under No. 597600/22 to the Committee on Inventions and the Opening of the Council of Ministers of the USSR

For the passage of preparatory and rifled workings, machines with an executive planetary type, equipped with crowns with incisors or hemispheres and a burr, are used to destroy the middle part of the section of development. However, well-known machines do not ensure the passage of workings with a geometric shape and cross-section.

To eliminate this drawback, it is proposed to drive the crown shafts or hemispheres of the executive body to pivotally connect to the transfer gearbox and through the hinge parallelogram to the cylinder of the hydraulic jack, and to provide the main shaft with an interchangeable shaped fist. This embodiment of the drive crown creates, in addition to the planetary, the reciprocating movement of the Executive body in the direction from the axis of the main shaft to the periphery of the output.

The drawing shows the kinematic scheme of the proposed machine in two projections.

The machine's executive body has independent supports and is separated from the undercarriage device (STA 1, which makes it possible to reduce the turning radius of the machine and create a working space for fastening the excavated output directly at the bottom. The working part of the machine with the executive body is connected to the undercarriage by the hinge device 2 .

The executive body consists of two hemispherical or conical crowns 3, which, rotating around their axis at the axis of generation with a variable radius, produce a treatment of 90% of the bottom section area. The destruction of coal in the middle part of the cutting section is carried out by the drill 4. Rotation to the executive body is transmitted from the engine 5, from (staked on the undercarriage of the machine, through intermediate gearbox 6, hinged shaft 7 and distributing gearbox 8.

The valleys of crowns 3 of the organ of the organ are connected pivotally to the dispensing gear 8 and through the articulated parallelogram 9 - to qi nos. 118437-2 -

lindrom hydraulic jack W, which tells them to reciprocate in the direction from the axis of the main shaft to the periphery of the mine. The variable radius of rotation of the crowns 3 is provided by the presence of an interchangeable profile fist on the main shaft of the working body (not shown in the drawing), which synchronously with the rotation of the working body acts through the hydraulic jack 10 on the hinge parallelogram 9, increasing or decreasing the angle of deviation of the axes of the crowns.

Repulsed coal is delivered by buckets located in a plane at an angle of 90 with respect to the crowns into the chute, along which it is poured onto a scraper loader and then onto a tape trans-j

porter //. Machine control in a vertical plane carried out;

It is supported by two hydraulic jacks. and in the horizontal plane — side hydraulic jacks 13. The machine is fed to the bottomhole — driven by a undercarriage /.

Claims (2)

1. A machine for passing preparatory and rifled workings with a planetary-type executive body equipped with crowns or hemispheres, equipped with incisors for destroying the periphery of the working part of the working section and a burr for the middle part of the section that differs from -) personal geometric shape and section, shafts crowns or hemispheres | the executive body is made pivotally connected to the dispensing gearbox and via a tarnier parallelogram - to the cylinder of a hydraulic cylinder; and the main shaft is equipped with an interchangeable profiled fist acting on the hydraulic engine, which creates, in addition to the planetary one, reciprocating movement of crowns or hemispheres in the direction from the axis of the main shaft to the periphery of production. 2. The form of the machine according to claim 1, characterized in that, in order to reduce the turning radius of the machine and create a working space for the erection of the mount, the machine is made divided into two parts, the chassis and the working, interconnected by an articulated device.
