Description

one

The invention is intended for use in the mining industry.

According to the main author. in II53.5I, the working body of the tunneling machine consists of two HJja milling discs with two located in parallel flat perpendicular | the chest of the chest, rotating in opposite directions and having a portable movement relative to the axis of the carrier.

In the proposed working body milling discs are made with removable norpy304HHf G blades incisors.

This facilitates the driving of the combine from the excavated output.

Figs, 1 shows the proposed working body, side view; figure 2 - the working body with the removed ogmentshly milling discs, front view; on fig.Z - milling disc (section along aa on figd), the proposed working body

Includes milling discs I with a cutter. Turned on the a and the zaburnik 4. The milling discs are made with Cyclic segments 5 The milling disc is rigidly mounted on the output shaft of a gear 6 placed in building 7, Removable segments b are attached to the milling disc, for example. by fingers 8 From production.

0 free fall fingers 8 held CTonopafviH 9 Each milling disc can have several removable segments. Removable segments have incisors 2 and loading lo5 patkn 10 in

Milling discs I make a complex movement: rotation around their axes A with the help of gear gear 6 and portable daiJJsne -

0 together with the carrier 3.

During the rotation of the milling discs drove and zaburnikov with the supply code to the bottom is carried out to develop a certain diameter d

5 Even as it is necessary for the combine to pasture out of the development of the knocking-out finger 8 and remove the segments 5 This achieves a reduction in the diameter of the entire working body to Aj,

The combine is driven out of the mine;

PRIORITY OF THE INVENTION
