Description

The invention relates to mining machines for the development and excavation of rocks and minerals and can be used for the development of frozen soils in the construction of various objects.

The purpose of the invention is to increase the efficiency of destruction of hard rock and minerals, productivity, reliability of the cutting tool and the executive body by ensuring the constancy of the cutting angle

The drawing shows the kinematic scheme of the proposed executive body, a longitudinal section in the vertical plane.

The mining machine contains a cutting disk 1 with a cutting tool 2, the axis of which is movably fixed in the support 3, a double spherical joint

4 with weekend VSHSHOM 5, INPUT 6 and

drive 7 shafts, arrows 8 of the executive body. Bearing 3 cutting. The disk 1 is movably connected by spherical hinges 9 to the rods of 10 jacks, and the cylinders 11 of jacks are movably connected by spherical hinges 12 to the body of the combine, forming a parallelogram.

The combine works as follows.

From the engine, the rotational drive is transmitted to the telescopic drive shaft 7, which rotates the input. Editor M. Blanard Order 3074/33

Noah shaft 6 double spherical hinge A and the output shaft 5 with a cutting disk 2, equipped with cutting tools 2, which destroy the array. When the boom 8 rotates in a vertical or horizontal plane, the jacks, consisting of the rods 10 and cylinders 11, are kinematically connected with the support 3 and the combine body with spherical hinges 9 and 12, simultaneously rotate with it, and the support 3 of the cutting disk 1 moves progressively along the bottom of the chest at a fixed position of the axis X of the cutting disc relative to the axis of the combine and the breast of the bottom in any position of the boom 8. For effective drilling, the length of one of the jacks is changed, while bearing 3 is rotated with the axis X of the cutting disc in either direction on the necessity 1 & the angle is Y (shown by a dotted line), and the double spherical hinge ensures the transmission of torque to the resisting disk independently at what angle relative to one another the axes of the input 6 and output 5 of its shafts are located, ensuring their constant angular speed.

The turn of the support with the cutting disc can be carried out both in the vertical and in the horizontal planes. After the lengths of the jacks are drilled, they are removed.
